    This study was undertaken to determine the effects of various resuscitation regimens on lung perfusion following resuscitation from hemorrhagic shock. Fourty male Sprague-Dawley rats (250-300 g) were used. The rats were divided randomly into four groups (n=10 for each) and were sedated with intramuscular ketamine (100 mg/kg). We measured blood pressure, rectal temperature and lung perfusion using radioscintigraphy with a technetium colloid indicator. The systolic blood pressure was decreased 75% by removing blood via v. jugularis in the first three groups and group 4 was accepted as the control group, and blood volume was not diminished. Then the first three groups were resuscitated with autologous blood containing 125 units heparine/ml in group 1, saline in group 2, and hydroxyethyl starch (HES) 6% in group 3. After the correction of hypovolemia, all animals were injected 100 Bg (0.1 cc) technetium 99m macroaggregated albumin ({sup 99m}Tc MAA) via penil vein. After injection of {sup 99m}Tc MAA, 3 minutes fixed images were detected by a {gamma} camera in posterior position at 15 minutes and 5 hours. {sup 99m}Tc MMA ''wash out'' rate in lung was determined quantitatively at 5 hours. Compared to a control group, lung perfusion was decreased significantly in groups resuscitated with saline, and HES 6% while perfusion was restored with autologous blood. We conclude that heparinized autologous blood saved lung capillary circulation in hemorrhagic shock in rats. (author)

    This study was done, using a swine model of prolonged ventricular fibrillation out-of-hospital cardiac arrest, to determine the feasibility of inducing therapeutic hypothermia after successful resuscitation by giving an intraosseous infusion of iced saline. This study was IACUC approved. Liter bags of normal saline, after being refrigerated for at least 24h, were placed in an ice filled cooler. Female Yorkshire swine weighing between 27 and 35 kg were sedated and instrumented under general anesthesia. A temperature probe was inserted 10 cm into the esophagus. Ventricular fibrillation was electrically induced and allowed to continue untreated for 10 min. Animals were randomized to one of two resuscitation schemes for the primary study (N=53). One group had central intravenous access for drug delivery and the other had an intraosseous needle inserted into the proximal tibia for drug administration. Animals in which spontaneous circulation was restored were immediately cooled, for this secondary study, by means of a rapid, pump-assisted infusion of 1L of iced saline either through the intraosseous needle (n=8), the central access (n=6), or a peripheral intravenous catheter (n=7) in a systematic, non-randomized fashion. Room, animal, and saline temperatures were recorded at initiation and upon completion of infusion. The data were analyzed descriptively using Stata SE v8.1 for Macintosh. The baseline characteristics of all three groups were mathematically the same. The average ambient room temperature during the experimental sessions was 25.5 degrees C (SD=1.3 degrees C). There were no statistically significant differences between the three groups with regard to saline temperature, rate of infusion, or decrease in core body temperature. The decrease in core temperature for the intraosseous group was 2.8 degrees C (95% CI=1.8, 3.8) over the infusion period. Mild therapeutic hypothermia can be effectively induced in swine after successful resuscitation of prolonged

    The original purpose of this study was to compare initial resuscitation of hemorrhagic hypotension after traumatic brain injury (TBI) with saline and shed blood. Based on those results, the protocol was modified and saline was compared to a blood substitute, diaspirin cross-linked hemoglobin (DCLHb). Two series of experiments were performed in anesthetized and mechanically ventilated (FiO2 = 0.4) pigs (35-45 kg). In Series 1, fluid percussion TBI (6-8 ATM) was followed by a 30% hemorrhage. At 120 min post-TBI, initial resuscitation consisted of either shed blood (n = 7) or a bolus of 3x shed blood volume as saline (n = 13). Saline supplements were then administered to all pigs to maintain a systolic arterial blood pressure (SAP) of >100 mmHg and a heart rate (HR) of 100 mmHg and a HR of CO2 reactivity was preserved with blood vs. saline (all P CO2 reactivity were improved, and ScvO2 was lower with DCLHb vs. saline (P effective than saline for resuscitation of TBI, whereas DCLHb was no more, and according to many variables, less effective than saline resuscitation. These experimental results are comparable to those in a recent multicenter trial using DCLHb for the treatment of severe traumatic shock. Further investigations in similar experimental models might provide some plausible explanations why DCLHb unexpectedly increased mortality in patients.

    Secondary abdominal compartment syndrome is a lethal complication after resuscitation from burn shock. Hypertonic lactated saline (HLS) infusion reduces early fluid requirements in burn shock, but the effects of HLS on intraabdominal pressure have not been clarified. Patients admitted to our burn unit between 2002 and 2004 with burns > or =40% of the total body surface area without severe inhalation injury were entered into a fluid resuscitation protocol using HLS (n = 14) or lactated Ringer's solution (n = 22). Urine output was monitored hourly with a goal of 0.5 to 1.0 mL/kg per hour. Hemodynamic parameters, blood gas analysis, intrabladder pressure as an indicator of intraabdominal pressure (IAP), and the peak inspiratory pressure were recorded. Pulmonary compliance and the abdominal perfusion pressure were also calculated. In the HLS group, the amount of intravenous fluid volume needed to maintain adequate urine output was less at 3.1 +/- 0.9 versus 5.2 +/- 1.2 mL/24 h per kg per percentage of total body surface area, and the peak IAP and peak inspiratory pressure at 24 hours after injury were significantly lower than those in the lactated Ringer's group. Two of 14 patients (14%) in the HLS group and 11 of 22 patients (50%) developed IAH within 20.8 +/- 7.2 hours after injury. In patients with severe burn injury, a large intravenous fluid volume decreases abdominal perfusion during the resuscitative period because of increased IAP. Our data suggest that HLS resuscitation could reduce the risk of secondary abdominal compartment syndrome with lower fluid load in burn shock patients.

    Full Text Available The purpose of present study was to assess the effects of thoracic epidural anesthesia on splanchnic perfusion, bacterial translocation and histopathologic changes in experimental hemorrhagic shock in short-tailed macaques (Macaca nemestrina. Sixteen Macaca nemestrinas were randomly assigned to one of two groups i.e. the lidocaine group (n = 8, receiving general anesthesia plus lidocaine thoracic epidural anesthesia; and the saline group (n = 8, receiving general anesthesia alone as control. Hemorrhagic shock was induced by withdrawing blood gradually to a mean arterial pressure (MAP of 40 mm Hg, and maintained for 60 minutes. Animals were then resuscitated with their own blood and ringer lactate solution (RL. After resuscitation, epidural lidocaine 2% was given in the lidocaine group and saline in the control group. Resuscitation that was performed after one hour hemorrhagic shock, with hemodynamic variables and urine output returned to normal, revealed there was no improvement of splanchnic perfusion. PgCO2, P(g-aCO2, and pHi remained in critical value and tended to deteriorate in the saline group. Contrast to saline group, splanchnic perfusion in lidocaine group tended to improve. This condition was supported by the finding of less bacterial translocation and better histopathologic changes in lidocaine thoracic epidural anesthesia group than in saline group. This study concludes that lidocaine thoracic epidural anesthesia attenuates splachnic hypoperfusion in post-resuscitation hemorrhagic shock in Macaca nemestrina.

    It is not known whether naloxone is as efficacious as epinephrine during cardiopulmonary resuscitation (CPR). The aim of the study was to compare the effects of naloxone and epinephrine on the outcomes of CPR following asphyxial cardiac arrest in rats. Cardiac arrest was induced with asphyxia by clamping the tracheal tubes. Twenty-four Sprague-Dawley rats were randomized prospectively into a saline group (treated with normal saline, 1 ml intravenously, n = 8), an epinephrine group (treated with epinephrine, 0.04 mg/kg intravenously, n = 8) or a naloxone group (treated with naloxone, 1 mg/kg intravenously, n = 8) in a blind fashion during resuscitation after asphyxial cardiac arrest. After 5 min of untreated cardiac arrest, conventional manual CPR was started and each drug was administered at the same time. The rates of restoration of spontaneous circulation (ROSC) were one of eight (12.5%), seven of eight (87.5%) and seven of eight (87.5%) in the saline, epinephrine and naloxone groups, respectively. The rates of ROSC in the epinephrine and naloxone groups were equal and significantly greater than that in the saline group (P = 0.01 and P = 0.01, respectively). The administration of naloxone or epinephrine alone may increase the resuscitation rate, and both drugs are equally effective for CPR in a rat asphyxia model. However, the mechanism by which naloxone produces its efficacy during CPR remains unclear and further experimentation will be necessary.

    Context Hypertonic fluids restore cerebral perfusion with reduced cerebral edema and modulate inflammatory response to reduce subsequent neuronal injury and thus have potential benefit in resuscitation of patients with traumatic brain injury (TBI). Objective To determine whether out-of-hospital administration of hypertonic fluids improves neurologic outcome following severe TBI. Design, Setting, and Participants Multicenter, double-blind, randomized, placebo-controlled clinical trial involving 114 North American emergency medical services agencies within the Resuscitation Outcomes Consortium, conducted between May 2006 and May 2009 among patients 15 years or older with blunt trauma and a prehospital Glasgow Coma Scale score of 8 or less who did not meet criteria for hypovolemic shock. Planned enrollment was 2122 patients. Intervention A single 250-mL bolus of 7.5% saline/6% dextran 70 (hypertonic saline/dextran), 7.5% saline (hypertonic saline), or 0.9% saline (normal saline) initiated in the out-of-hospital setting. Main Outcome Measure Six-month neurologic outcome based on the Extended Glasgow Outcome Scale (GOSE) (dichotomized as >4 or ≤4). Results The study was terminated by the data and safety monitoring board after randomization of 1331 patients, having met prespecified futility criteria. Among the 1282 patients enrolled, 6-month outcomes data were available for 1087 (85%). Baseline characteristics of the groups were equivalent. There was no difference in 6-month neurologic outcome among groups with regard to proportions of patients with severe TBI (GOSE ≤4) (hypertonic saline/dextran vs normal saline: 53.7% vs 51.5%; difference, 2.2% [95% CI, −4.5% to 9.0%]; hypertonic saline vs normal saline: 54.3% vs 51.5%; difference, 2.9% [95% CI, −4.0% to 9.7%]; P=.67). There were no statistically significant differences in distribution of GOSE category or Disability Rating Score by treatment group. Survival at 28 days was 74.3% with hypertonic saline

    2010-01-01

    Full Text Available Abstract Background Traumatic brain injury (TBI initiates interrelated inflammatory and coagulation cascades characterized by wide-spread cellular activation, induction of leukocyte and endothelial cell adhesion molecules and release of soluble pro/antiinflammatory cytokines and thrombotic mediators. Resuscitative care is focused on optimizing cerebral perfusion and reducing secondary injury processes. Hypertonic saline is an effective osmotherapeutic agent for the treatment of intracranial hypertension and has immunomodulatory properties that may confer neuroprotection. This study examined the impact of hypertonic fluids on inflammatory/coagulation cascades in isolated head injury. Methods Using a prospective, randomized controlled trial we investigated the impact of prehospital resuscitation of severe TBI (GCS vs 0.9% normal saline (NS, on selected cellular and soluble inflammatory/coagulation markers. Serial blood samples were drawn from 65 patients (30 HSD, 35 NS at the time of hospital admission and at 12, 24, and 48-h post-resuscitation. Flow cytometry was used to analyze leukocyte cell-surface adhesion (CD62L, CD11b and degranulation (CD63, CD66b molecules. Circulating concentrations of soluble (sL- and sE-selectins (sL-, sE-selectins, vascular and intercellular adhesion molecules (sVCAM-1, sICAM-1, pro/antiinflammatory cytokines [tumor necrosis factor (TNF-α and interleukin (IL-10], tissue factor (sTF, thrombomodulin (sTM and D-dimers (D-D were assessed by enzyme immunoassay. Twenty-five healthy subjects were studied as a control group. Results TBI provoked marked alterations in a majority of the inflammatory/coagulation markers assessed in all patients. Relative to control, NS patients showed up to a 2-fold higher surface expression of CD62L, CD11b and CD66b on polymorphonuclear neutrophils (PMNs and monocytes that persisted for 48-h. HSD blunted the expression of these cell-surface activation/adhesion molecules at all time-points to

    Full Text Available This study was contemplated to determine the comparative beneficial effects of hypertonic saline solution and sterile saline solution in induced endotoxic shock in dogs. For this purpose, 12 healthy Mongrel dogs were randomly divided into two equal groups (A and B. All the animals were induced endotoxaemia by slow intravenous administration of Escherichia coli endotoxins 0111:B4. Group A was treated with normal saline solution @ 90 ml/kg BW, while group B was given hypertonic saline solution @ 4 ml/kg BW, followed by normal saline solution @ 10 ml/kg BW. Different parameters were observed for evaluation of these fluids including clinical and haematological parameters, serum electrolytes, mean arterial pressure, and blood gases at different time intervals up to 24 hours post treatments. After infusion of respective fluids, all parameters returned to baseline values in both the groups but group B showed better results than group A except bicarbonates, which better recovered in group A. Thus, it was concluded that a small-volume of hypertonic saline solution could be effectively used in reversing the endotoxaemia. Moreover, it provides a rapid and inexpensive resuscitation from endotoxic shock.

    Communication during resuscitation is essential for the provision of coordinated, effective care. Previously, we observed 44% of resuscitation communication originated from participants other than the physician team leader; 65% of which was directed to the team, exclusive of the team leader. We called this outer-loop communication. This institutional review board-approved qualitative study used grounded theory analysis of focus groups and interviews to describe and define outer-loop communication and the role of "event manager" as an additional "leader." Participants were health care staff involved in the medical management of resuscitations in a quaternary pediatric academic hospital. The following 3 domains were identified: the existence and rationale of outer-loop communication; the functions fulfilled by outer-loop communication; and the leadership and learning of event manager skills. The role was recognized by all team members and evolved organically as resuscitation complexity increased. A "good" manager has similar qualities to a "good team leader" with strong nontechnical skills. Event managers were not formally identified and no specific training had occurred. "Outer-loop" communication supports resuscitation activities. An event manager gives direction to the team, coordinates activities, and supports the team leader. We describe a new role in resuscitation in light of structural organizational theory and cognitive load with a view to incorporating this structure into resuscitation training.

    Hemorrhagic shock (HS) still has a high mortality rate and none of the known resuscitative regimens completely reverse its adverse outcomes. This study investigated the effects of different models of resuscitative therapy on the healing of organ damage in a HS model. Male Wistar rats were randomized into six groups: Sham, without HS induction; HS, without resuscitation; HS+Blood, resuscitation with the shed blood; HS+Blood+NS, resuscitation with blood and normal saline; HS+Blood+RL, resuscitation with blood and Ringer's lactate; EPO, erythropoietin was added to the blood and RL. Blood and urine samples were obtained 3 h after resuscitation. Kidney, liver and brain tissue samples were harvested for multiple organ failure evaluation. Survival rate was the highest in the Sham, EPO and HS+Blood+RL groups compared to others. Plasma creatinine concentration, ALT, AST, urinary NAG activity and renal NGAL mRNA expression significantly increased in the HS+Blood+RL group compared to the Sham group. There was a significant increase in tissue oxidative stress markers and pro-inflammatory cytokines in HS+Blood+RL group compared to the Sham rats. EPO had more protective effects on multiple organ failure compared to the HS+Blood+RL group. EPO, as a resuscitative treatment, attenuated HS-induced organ damage. It seems that it has a potential to be attractive for clinical trials.

    Ischaemic contracture compromises the haemodynamic effectiveness of cardiopulmonary resuscitation and resuscitability. 2,3-Butanedione monoxime (BDM) reduced ischaemic contracture by inhibiting actin-myosin crossbridge formation in an isolated heart model. We investigated the effects of BDM on ischaemic contracture and resuscitation outcomes in a pig model of out-of-hospital cardiac arrest (OHCA). After 15min of untreated ventricular fibrillation, followed by 8min of basic life support, 16 pigs were randomised to receive either 2mlkg(-1) of BDM solution (25gl(-1)) or 2mlkg(-1) of saline during advanced cardiac life support (ACLS). During the ACLS, the control group showed an increase in left ventricular (LV) wall thickness from 10.0mm (10.0-10.8) to 13.0mm (13.0-13.0) and a decrease in LV chamber area from 8.13cm(2) (7.59-9.29) to 7.47cm(2) (5.84-8.43). In contrast, the BDM group showed a decrease in the LV wall thickness from 10mm (9.0-10.8) to 8.5mm (7.0-9.8) and an increase in the LV chamber area from 9.86cm(2) (7.22-12.39) to 12.15 cm(2) (8.02-14.40). Mixed model analyses of the LV wall thickness and LV chamber area revealed significant group effects and group-time interactions. Spontaneous circulation was restored in four (50%) animals in the control group and in eight (100%) animals in the BDM group (p=0.077). All the resuscitated animals survived during an intensive care period of 4h. BDM administered during cardiopulmonary resuscitation reversed ischaemic contracture in a pig model of OHCA.

    To compare the use of polymerized stroma-free bovine hemoglobin (Hb-200) and 6% hetastarch 450/0.7 (HES 450/0.7) in 0.9% saline during fluid resuscitation of dogs with gastric dilatation-volvulus (GDV). Prospective, randomized clinical case series. Private specialty and referral clinic. Twenty client-owned dogs presenting with GDV. Dogs presenting with GDV and abnormal perfusion parameters first received rapid IV infusion of a buffered isotonic replacement crystalloid (15 mL/kg) and IV opioids. Patients were then randomized to receive either Hb-200 (N = 10) or HES 450/0.7 (N = 10). Balanced isotonic replacement crystalloids (10-20 mL/kg IV) were rapidly infused along with either Hb-200 or HES in 5 mL/kg IV aliquots to meet resuscitation end points. Resuscitation was defined as meeting at least 2 of 3 criteria: (1) capillary refill time 1-2 seconds, pink mucous membrane color, strong femoral pulse quality; (2) heart rate (HR) ≤ 150/min; or (3) indirect arterial systolic blood pressure (SBP) > 90 mm Hg. HR, SBP, packed cell volume, hemoglobin, glucose, venous pH, bicarbonate, base excess, anion gap, and colloid osmotic pressure were compared at hospital entry and within 30 minutes post-resuscitation. Compared to the HES group, the Hb-200 group required significantly less colloid (4.2 versus 18.4 mL/kg) and crystalloid (31.3 versus 48.1 mL/kg) to reach resuscitation end points (P = 0.001). Time to resuscitation was significantly shorter in the Hb-200 group (12.5 versus 52.5 min). Dogs with GDV receiving Hb-200 during initial resuscitation required smaller volumes of both crystalloid and colloid fluids and reached resuscitation end points faster than dogs receiving HES 450/0.7 (P = 0.02). © Veterinary Emergency and Critical Care Society 2012.

Hepatic oxidative (4-hydroxynonenal, 4-HNE and nitrosative (3-nitrotyrosine, 3-NT stress were significantly reduced in EtOH-gavaged rats compared to controls after H/R. Proapoptotic caspase-8 and Bax expressions were markedly diminished in EtOH-gavaged animals compared with controls 2 h after resuscitation. EtOH-gavage increased antiapoptotic Bcl-2 gene expression compared with controls 2 h after resuscitation. iNOS protein expression increased following H/R but was attenuated in EtOH-gavaged animals after H/R. Taken together, the data suggest that acute EtOH-gavage may attenuate H/R-induced oxidative stress thereby reducing cellular injury in rat liver.

    The International Liaison Committee on Resuscitation (ILCOR), with representation from North America, Europe, Australia, New Zealand, Africa, and South America, was formed in 1992 to provide a forum for liaison between resuscitation organizations in the developed world. This consensus document on resuscitation extends previously published ILCOR advisory statements on resuscitation to address the unique and changing physiology of the newly born infant within the first few hours after birth and the techniques for providing advanced life support. After careful review of the international resuscitation literature and after discussion of key and controversial issues, consensus was reached on almost all aspects of neonatal resuscitation, and areas of controversy and high priority for additional research were delineated. Consensus on resuscitation for the newly born infant included the following principles: Common or controversial medications (epinephrine, volume expansion, naloxone, bicarbonate), special resuscitation circumstances affecting care of the newly born, continuing care of the newly born after resuscitation, and ethical considerations for initiation and discontinuation of resuscitation are discussed. There was agreement that insufficient data exist to recommend changes to current guidelines regarding the use of 21% versus 100% oxygen, neuroprotective interventions such as cerebral hypothermia, use of a laryngeal mask versus endotracheal tube, and use of high-dose epinephrine. Areas of controversy are identified, as is the need for additional research to improve the scientific justification of each component of current and future resuscitation guidelines.

    Cardiac arrest has a high mortality in children. To improve the performance of cardiopulmonary resuscitation, it is essential to disseminate the international recommendations and the training of health professionals and the general population in resuscitation. This article summarises the 2015 European Paediatric Cardiopulmonary Resuscitation recommendations, which are based on a review of the advances in cardiopulmonary resuscitation and consensus in the science and treatment by the International Council on Resuscitation. The Spanish Paediatric Cardiopulmonary Resuscitation recommendations, developed by the Spanish Group of Paediatric and Neonatal Resuscitation, are an adaptation of the European recommendations, and will be used for training health professionals and the general population in resuscitation. This article highlights the main changes from the previous 2010 recommendations on prevention of cardiac arrest, the diagnosis of cardiac arrest, basic life support, advanced life support and post-resuscitation care, as well as reviewing the algorithms of treatment of basic life support, obstruction of the airway and advanced life support.

    2013-03-14

    The Fluid Expansion as Supportive Therapy (FEAST study) was an extremely well conducted study that gave unexpected results. The investigators had reported that febrile children with impaired perfusion treated in low-income countries without access to intensive care are more likely to die if they receive bolus resuscitation with albumin or saline compared with no bolus resuscitation at all. In a secondary analysis of the trial, published in BMC Medicine, the authors found that increased mortality was evident in patients who presented with clinical features of severe shock in isolation or in conjunction with features of respiratory or neurological failure. The cause of excess deaths was primarily refractory shock and not fluid overload. These features are consistent with a potential cardiotoxic or ischemia-reperfusion injury following resuscitation with boluses of intravenous fluid. Although these effects may have been amplified by the absence of invasive monitoring, mechanical ventilation or vasopressors, the results provide compelling insights into the effects of intravenous fluid resuscitation and potential adverse effects that extend beyond the initial resuscitation period. These data add to the increasing body of literature about the safety and efficacy of intravenous resuscitation fluids, which may be applicable to management of other populations of critically ill patients.

  7. Conflicting perspectives compromising discussions on cardiopulmonary resuscitation.

    Healthcare professionals, patients and their relatives are expected to discuss resuscitation together. This study aims to identify the differences in the knowledge base and understanding of these parties. Questionnaires examining knowledge and opinion on resuscitation matters were completed during interviews of randomly selected doctors, nurses and the general public. 70% doctors, 24% nurses and 0% of a public group correctly estimated survival to discharge following in-hospital resuscitation attempts. Deficiencies were identified in doctor and nurse knowledge of ethics governing resuscitation decisions. Public opinion often conflicts with ethical guidelines. Public understanding of the nature of cardiopulmonary arrests and resuscitation attempts; and of the implications of a \\'Do Not Attempt Resuscitation (DNAR)\\' order is poor. Television medical dramas are the primary source of resuscitation knowledge. Deficiencies in healthcare professionals\\' knowledge of resuscitation ethics and outcomes may compromise resuscitation decisions. Educational initiatives to address deficiencies are necessary. Parties involved in discussion on resuscitation do not share the same knowledge base reducing the likelihood of meaningful discussion. Public misapprehensions surrounding resuscitation must be identified and corrected during discussion.

    The advanced life support guidelines recommend 2min of cardiopulmonary resuscitation (CPR) and minimal hands-off time to ensure sufficient cardiac and cerebral perfusion. We have observed doctors who shorten the CPR intervals during resuscitation attempts. During simulation-based resuscitation training, the recommended 2-min CPR cycles are often deliberately decreased in order to increase the number of scenarios. The aim of this study was to test if keeping 2-min CPR cycles during resuscitation training ensures better adherence to time during resuscitation in a simulated setting. This study was designed as a randomised control trial. Fifty-four 4th-year medical students with no prior advanced resuscitation training participated in an extra-curricular one-day advanced life support course. Participants were either randomised to simulation-based training using real-time (120s) or shortened CPR cycles (30-45s instead of 120s) in the scenarios. Adherence to time was measured using the European Resuscitation Council's Cardiac Arrest Simulation Test (CASTest) in retention tests conducted one and 12 weeks after the course. The real-time group adhered significantly better to the recommended 2-min CPR cycles (time-120s) (mean 13; standard derivation (SD) 8) than the shortened CPR cycle group (mean 45; SD 19) when tested (ptraining to optimise outcome.

    Ischemic contracture compromises the hemodynamic effectiveness of cardiopulmonary resuscitation (CPR) and resuscitability from cardiac arrest. In a pig model of cardiac arrest, 2,3-butanedione monoxime (BDM) attenuated ischemic contracture. We investigated the effects of different doses of BDM to determine whether increasing the dose of BDM could improve the hemodynamic effectiveness of CPR further, thus ultimately improving resuscitability. After 16minutes of untreated ventricular fibrillation and 8minutes of basic life support, 36 pigs were divided randomly into 3 groups that received 50mg/kg (low-dose group) of BDM, 100mg/kg (high-dose group) of BDM, or an equivalent volume of saline (control group) during advanced cardiovascular life support. During advanced cardiovascular life support, the control group showed an increase in left ventricular (LV) wall thickness and a decrease in LV chamber area. In contrast, the BDM-treated groups showed a decrease in the LV wall thickness and an increase in the LV chamber area in a dose-dependent fashion. Mixed-model analyses of the LV wall thickness and LV chamber area revealed significant group effects and group-time interactions. Central venous oxygen saturation at 3minutes after the drug administration was 21.6% (18.4-31.9), 39.2% (28.8-53.7), and 54.0% (47.5-69.4) in the control, low-dose, and high-dose groups, respectively (Pfashion.

    Fluid resuscitation of burned children is challenging because of their small size and intolerance to over- or underresuscitation. Our American Burn Association-verified regional burn center has used colloid "rescue" as part of our pediatric resuscitation protocol. With Institutional Review Board approval, the authors reviewed children with ≥15% TBSA burns admitted from January 1, 2004, to May 1, 2009. Resuscitation was based on the Parkland formula, which was adjusted to maintain urine output. Patients requiring progressive increases in crystalloid were placed on a colloid protocol. Results were expressed as an hourly resuscitation ratio (I/O ratio) of fluid infusion (ml/kg/%TBSA/hr) to urine output (ml/kg/hr). We reviewed 53 patients; 29 completed resuscitation using crystalloid alone (lactated Ringer's solution [LR]), and 24 received colloid supplementation albumin (ALB). Groups were comparable in age, gender, weight, and time from injury to admission. ALB patients had more inhalation injuries and larger total and full-thickness burns. LR patients maintained a median I/O of 0.17 (range, 0.08-0.31), whereas ALB patients demonstrated escalating ratios until the institution of albumin produced a precipitous return of I/O comparable with that of the LR group. Hospital stay was lower for LR patients than ALB patients (0.59 vs 1.06 days/%TBSA, P = .033). Twelve patients required extremity or torso escharotomy, but this did not differ between groups. There were no decompressive laparotomies. The median resuscitation volume for ALB group was greater than LR group (9.7 vs 6.2 ml/kg/%TBSA, P = .004). Measuring hourly I/O is a helpful means of evaluating fluid demands during burn shock resuscitation. The addition of colloid restores normal I/O in pediatric patients.

    Full Text Available Sepsis is one of the major causes of death and is the biggest obstacle preventing improvement of the success rate in curing critical illnesses. Currently, isotonic solutions are used in fluid resuscitation technique. Several studies have shown that hypertonic saline applied in hemorrhagic shock can rapidly increase the plasma osmotic pressure, facilitate the rapid return of interstitial fluid into the blood vessels, and restore the effective circulating blood volume. Here, we established a rat model of sepsis by using the cecal ligation and puncture approach. We found that intravenous injection of hypertonic saline dextran (7.5% NaCl/6% dextran after cecal ligation and puncture can improve circulatory failure at the onset of sepsis. We found that the levels of tumor necrosis factor-α, interleukin-1β, interleukin-6 and intracellular adhesion molecule 1 levels in the lung tissue of cecal ligation and puncture rats treated with hypertonic saline dextran were significantly lower than the corresponding levels in the control group. We inferred that hypertonic saline dextran has a positive immunoregulatory effect and inhibits the overexpression of the inflammatory response in the treatment of sepsis. The percentage of neutrophils, lung myeloperoxidase activity, wet to dry weight ratio of lung tissues, histopathological changes in lung tissues, and indicators of arterial blood gas analysis was significantly better in the hypertonic saline dextran-treated group than in the other groups in this study. Hypertonic saline dextran-treated rats had significantly improved survival rates at 9 and 18 h compared to the control group. Our results suggest that hypertonic saline dextran plays a protective role in acute lung injury caused after cecal ligation and puncture. In conclusion, hypertonic/hyperoncotic solutions have beneficial therapeutic effects in the treatment of an animal model of sepsis.

    Anaphylactic shock is a rare, but potentially lethal complication, combining life-threatening circulatory failure and massive fluid shifts. Treatment guidelines rely on adrenaline and volume expansion by intravenous fluids, but there is no solid evidence for the choice of one specific type of fluid over another. Our purpose was to compare the time to achieve target mean arterial pressure upon resuscitation using adrenaline alone versus adrenaline with different resuscitation fluids in an animal model and to compare the tissue oxygen pressures (PtiO2) with the various strategies. Twenty-five ovalbumin-sensitised Brown Norway rats were allocated to five groups after anaphylactic shock induction: vehicle (CON), adrenaline alone (AD), or adrenaline with isotonic saline (AD+IS), hydroxyethyl starch (AD+HES) or hypertonic saline (AD+HS). Time to reach a target mean arterial pressure value of 75 mmHg, cardiac output, skeletal muscle PtiO2, lactate/pyruvate ratio and cumulative doses of adrenaline were recorded. Non-treated rats died within 15 minutes. The target mean arterial pressure value was reached faster with AD+HES (median: 10 minutes, range: 7.5 to 12.5 minutes) and AD+IS (median: 17.5 minutes, range: 5 to 25 minutes) versus adrenaline alone (median: 25 minutes, range: 20-30 minutes). There were also reduced adrenaline requirements in these groups. The skeletal muscle PtiO2 was restored only in the AD+HES group. Although direct extrapolation to humans should be made with caution, our results support the combined use of adrenaline and volume expansion for resuscitation from anaphylactic shock. When used with adrenaline the most effective fluid was hydroxyethyl starch, whereas hypertonic saline was the least effective.

    To investigate the fluid tolerance of hemorrhagic shock with pulmonary edema (HSPE) at high altitude in unacclimated rats and the beneficial effect of 7.5% hypertonic saline/6% dextran (HSD). One hundred seventy-six Sprague-Dawley rats, transported to LaSa, Tibet, 3,760 m above the sea level, were anesthetized with sodium pentobarbital (30 mg/kg, i.p.) within 1 week. Hemorrhagic shock with pulmonary edema was induced by bloodletting (50 mmHg for 1 h) plus intravenous injection of oleic acid (50 microL/kg). Seventy-seven rats were equally divided into 11 groups (n = 7/group) including sham-operated control group; hemorrhagic shock control group; HSPE control group; HSPE plus 0.5-, 1.0-, 1.5-, 2.0-, or 3.0-fold volumes of lactated Ringer's solution (LR) groups; and HSPE plus 4, 6, and 8 mL/kg of HSD groups. Hemodynamic parameters including mean arterial blood pressure, left intraventricular systolic pressure, and the maximal change rate of intraventricular pressure rise or decline (+/-dp/dtmax) were observed at baseline and at 15, 30, 60, and 120 min after infusion; blood gases were measured at 30 and 120 min after infusion, and the water content of lung and brain was determined at 120 min after infusion. Additional 99 rats were used to observe the effect of these treatments on the survival time of HSPE rats; 0.5 volume of LR infusion slightly increased the mean arterial blood pressure, left intraventricular systolic pressure, and +/-dp/dtmax and prolonged the survival time of HSPE animals as compared with the HSPE group (P solution infusion, 1.5, 2, and 3 volumes, significantly deteriorated the hemodynamic parameters, increased the water content of lung, and decreased the survival time of HSPE animals. Hypertonic saline/6% dextran (4 - 8 mL/kg) significantly increased the hemodynamic parameters, improved the blood gases, decreased the water content of lung and brain, and prolonged the survival time of HSPE rats. Among the three dosages of HSD, 6 mL/kg of HSD had the

    Introduction: Logistic constraints on combat casualty care preclude traditional resuscitation strategies which can require volumes and weights 3 fold or greater than hemorrhaged volume. We present a review of quantitative analyses of clinical and animal data on small volume strategies using 1) hypertonic-hyperosmotic solutions (HHS); 2) hemoglobin based oxygen carriers (HBOCs) and 3) closed-loop infusion regimens.Methods and Results: Literature searches and recent queries to industry and academic researchers have allowed us to evaluate the record of 81 human HHS studies (12 trauma trials), 19 human HBOCs studies (3trauma trials) and two clinical studies of closed-loop resuscitation.There are several hundreds animal studies and at least 82 clinical trials and reports evaluating small volume7.2%-7.5% hypertonic saline (HS) most often combined with colloids, e.g., dextran (HSD) or hetastarch(HSS). HSD and HSS data has been published for 1,108 and 392 patients, respectively. Human studies have documented volume sparing and hemodynamic improvements. Meta-analyses suggest improved survival for hypotensive trauma patients treated with HSD with significant reductions in mortality found for patients with blood pressure blood use and lower mortality compared to historic controls of patients refusing blood. Transfusion reductions with HBOC use have been modest. Two HBOCs (Hemopure and Polyheme) are now in new or planned large-scale multicenter prehospital trials of trauma treatment. A new implementation of small volume resuscitation is closed-loop resuscitation (CLR), which employs microprocessors to titrate just enough fluid to reach a physiologic target . Animal studies suggest less risk of rebleeding in uncontrolled hemorrhage and a reduction in fluid needs with CLR. The first clinical application of CLR was treatment of burn shock and the US Army. Conclusions: Independently sponsored civilian trauma trials and clinical evaluations in operational combat conditions of

    Background Both the self inflating bag and the T-piece resuscitator are recommended for neonatal resuscitation, but many health care workers are unfamiliar with using the latter. A prospective, comparative, observational study was done to determine the ease and effectiveness of training of health care personnel in the two devices using infant training manikins. Methods 100 health care workers, who had no prior formal training in neonatal resuscitation, were divided into small groups and trained in the use of the two devices by qualified trainers. Assessment of cognitive skills was done by pre and post MCQs. Psychomotor skill was assessed post training on manikins using a 10-point objective score. Acceptance by users was ascertained by questionnaire. Assessments were also done after 24 h and 3 months. Comparison was done by Chi square and paired t-tests. Results Pre-training cognitive tests increased from 3.77 (+1.58) to 6.99 (+1.28) on day of training which was significant. Post training assessment of psychomotor skills showed significantly higher initial scores for the T-piece group (7.07 + 2.57) on day of training. Reassessment after 24 h showed significant improvement in cognitive scores (9.89 + 1.24) and psychomotor scores in both groups (8.86 + 1.42 for self inflating bag and 9.70 + 0.57 for T-piece resuscitator). After 3–6 months the scores in both domains showed some decline which was not statistically significant. User acceptability was the same for both devices. Conclusion It is equally easy to train health care workers in both devices. Both groups showed good short term recall and both devices were equally acceptable to the users. PMID:25609858

Meta-analyses suggest improved survival for hypotensive trauma patients treated with HSD with significant reductions in mortality found for patients with blood pressure surgery. HSD and HSS have received regulatory approval in 14 and 3 countries, respectively, with 81,000+ units sold. The primary reported use was head injury and trauma resuscitation. Complications and reported adverse events are surprisingly rare and not significantly different from other solutions.HBOCs are potent volume expanders in addition to oxygen carriers with volume expansion greater than standard colloids. Several investigators have evaluated small volume hyperoncotic HBOCs or HS-HBOC formulations for hypotensive and normotensive resuscitation in animals. A consistent finding in resuscitation with HBOCs is depressed cardiac output. There is some evidence that HBOCs more efficiently unload oxygen from plasma hemoglobin as well as facilitate RBC

  18. Obesity-induced hepatic hypoperfusion primes for hepatic dysfunction after resuscitated hemorrhagic shock.

    Obese patients (BMI>35) after blunt trauma are at increased risk compared to non-obese for organ dysfunction, prolonged hospital stay, infection, prolonged mechanical ventilation, and mortality. Obesity and non-alcoholic fatty liver disease (NAFLD) produce a low grade systemic inflammatory response syndrome (SIRS) with compromised hepatic blood flow, which increases with body mass index. We hypothesized that obesity further aggravates liver dysfunction by reduced hepatic perfusion following resuscitated hemorrhagic shock (HEM). Age-matched Zucker rats (Obese, 314-519 g & Lean, 211-280 g) were randomly assigned to 4 groups (n = 10-12/group): (1) Lean-Sham; (2) Lean, HEM, and resuscitation (HEM/RES); (3) Obese-Sham; and (4) Obese-HEM/RES. HEM was 40% of mean arterial pressure (MAP) for 60 min; RES was return of shed blood/5 min and 2 volumes of saline/25 min. Hepatic blood flow (HBF) using galactose clearance, liver enzymes and complete metabolic panel were measured over 4 h after completion of RES. Obese rats had increased MAP, heart rate, and fasting blood glucose and BUN concentrations compared to lean controls, required less blood withdrawal (mL/g) to maintain 40% MAP, and RES did not restore BL MAP. Obese rats had decreased HBF at BL and during HEM/RES, which persisted 4 h post RES. ALT and BUN were increased compared to Lean-HEM/RES at 4 h post-RES. These data suggest that obesity significantly contributes to trauma outcomes through compromised vascular control or through fat-induced sinusoidal compression to impair hepatic blood flow after HEM/RES resulting in a greater hepatic injury. The pro-inflammatory state of NAFLD seen in obesity appears to prime the liver for hepatic ischemia after resuscitated hemorrhagic shock, perhaps intensified by insidious and ongoing hepatic hypoperfusion established prior to the traumatic injury or shock.

    Small-volume resuscitation using hypertonic saline/hydroxyethyl starch 200/0.62 (HS-HES) has been shown to be an effective alternative to the administration of crystalloids or colloids in trauma patients. All i.v. fluids cause dose-related dilutional coagulopathy and show intrinsic effects on the hemostatic system, but only few data refer to functional consequences after small-volume resuscitation. Using thrombelastometry (ROTEM), we studied 30 pigs (weighing 35-45 kg) after withdrawal of 60% of blood volume [1484 mL (1369-1624 mL)] and receiving 4 mL/kg HS-HES for compensation of blood loss or 4% gelatin or 6% HES 130/0.4 in a 1:1 ratio to lost blood volume. To compare the ROTEM variables (coagulation time, clot formation time, alpha angle, clot firmness, and fibrinogen polymerization) with bleeding tendency, a hepatic incision was made and blood loss was measured. Median (25th, 75th percentile) fibrinogen polymerization was significantly higher after HS-HES infusion [11 mm (10, 11), P = 0.0034] when compared with administration of 4% gelatin [4.5 mm (3.0, 5.8)] or HES 130/0.4 [3.5 mm (2.3, 4.0)]. Median blood loss after liver incision was 725 mL (900, 375) after HS-HES, 1625 mL (1275, 1950) after 4% gelatin, and 1600 mL (1500, 1800) after 6% HES 130/0.4 (P = 0.004). Hemodynamic stabilization was traceable in all groups but showed differences regarding filling pressures. Resuscitation from hemorrhagic shock with HS-HES 200/0.62 results in less impairment of clot formation when compared with compensation of blood loss by administering 6% HES 130/0.4 or 4% gelatin.

    Ventricular fibrillation remains the leading cause of death in western societies. International organizations publish guidelines to follow in case of cardiac arrest. The aim of the present study is to assess whether the newly published guidelines record similar resuscitation success with the 2000 Advanced Life Support Guidelines on Resuscitation in a swine model of cardiac arrest. Nineteen landrace/large white pigs were used. Ventricular fibrillation was induced with the use of a transvenous pacing wire inserted into the right ventricle. The animals were randomized into two groups. In Group A, 10 animals were resuscitated using the 2000 guidelines, whereas in Group B, 9 animals were resuscitated using the 2005 guidelines. Both algorithms recorded similar successful resuscitation rates, as 60% of the animals in Group A and 44.5% in Group B were successfully resuscitated. However, animals in Group A restored a rhythm, compatible with a pulse, quicker than those in Group B (p=0.002). Coronary perfusion pressure (CPP) was not adversely affected by three defibrillation attempts in Group A. Both algorithms' resulted in comparable resuscitation success, however, guidelines 2000 resulted in faster resuscitation times. These preliminary results merit further investigation.

    Fluid resuscitation is one of the critical treatments for the major burn patient in the early phases after injury. We evaluated the practice of fluid resuscitation for severely burned patients with the Third Military Medical University (TMMU) protocol, which is most widely used in many regions of China. Patients with major burns (>30% total body surface area (TBSA)) presenting to Southwest Hospital, Third Military Medical University, between January 2005 and October 2007, were included in this study. Fluid resuscitation was initiated by the TMMU protocol. A total of 71 patients were (46 adults and 25 children) included in this study. All patients survived the first 48 h after injury smoothly and none developed abdominal compartment syndrome or other recognised complications associated with fluid resuscitation. The average quantity of fluid infused was 3.3-61.33% more than that calculated based on the TMMU protocol in both adult and paediatric groups. The average urine output during the first 24h after injury was about 1.2 ml per kg body weight per hour in the two groups, but reached 1.2 ml and 1.7 ml during the second 24h in adult and pediatric groups, respectively. This study indicates that the TMMU protocol for fluid resuscitation is a feasible option for burn patients. Individualised resuscitation - guided by the physiological response to fluid administration - is still important as in other protocols.

    The optimal oxygen administration strategy during resuscitation from hemorrhagic shock (HS) is still controversial. Improving oxygenation and mitigating oxidative stress simultaneously seem to be contradictory goals. To maximize oxygen delivery while minimizing oxidative damage, the authors proposed the notion of gradually increased oxygen administration (GIOA), which entails making the arterial blood hypoxemic early in resuscitation and subsequently gradually increasing to hyperoxic, and compared its effects with normoxic resuscitation, hyperoxic resuscitation, and hypoxemic resuscitation in severe HS. Rats were subjected to HS, and on resuscitation, the rats were randomly assigned to four groups (n = 8): the normoxic, the hyperoxic, the hypoxemic, and the GIOA groups. Rats were observed for an additional 1 h. Hemodynamics, acid-base status, oxygenation, and oxidative injury were observed and evaluated. Central venous oxygen saturation promptly recovered only in the hyperoxic and the GIOA groups, and the liver tissue partial pressure of oxygen was highest in the GIOA group after resuscitation. Oxidative stress in GIOA group was significantly reduced compared with the hyperoxic group as indicated by the reduced malondialdehyde content, increased catalase activity, and the lower histologic injury scores in the liver. In addition, the tumor necrosis factor-α and interleukin-6 expressions in the liver were markedly decreased in the GIOA group than in the hyperoxic and normoxic groups as shown by the immunohistochemical staining. GIOA improved systemic/tissue oxygenation and mitigated oxidative stress simultaneously after resuscitation from severe HS. GIOA may be a promising strategy to improve resuscitation from HS and deserves further investigation.

    Long-term survival after cardiac arrest (CA) due to shock-refractory ventricular fibrillation (VF) is low. Clearly, there is a need for new pharmacological interventions in the setting of cardiopulmonary resuscitation (CPR) to improve outcome. Here, hemodynamic parameters and cardiac damage are compared between the treatment group (milrinone, esmolol and vasopressin) and controls (vasopressin only) during resuscitation from prolonged CA in piglets. A total of 26 immature male piglets were subjected to 12-min VF followed by 8-min CPR. The treatment group (n=13) received i.v. (intravenous) boluses vasopressin 0.4 U/kg, esmolol 250 μg/kg and milrinone 25 μg/kg after 13 min, followed by i.v. boluses esmolol 375 μg/kg and milrinone 25 μg/kg after 18 min and continuous esmolol 15 μg/kg/h infusion during 180 min reperfusion, whereas controls (n=13) received equal amounts of vasopressin and saline. A 200 J monophasic counter-shock was delivered to achieve resumption of spontaneous circulation (ROSC) after 8 min CPR. If ROSC was not achieved, another 200 J defibrillation and bolus vasopressin 0.4 U/kg would be administered in both groups. Direct current shocks at 360 J were applied as one shot per minute over maximally 5 min. Hemodynamic variables and troponin I as a marker of cardiac injury were recorded. Troponin I levels after 180 min reperfusion were lower in the treatment group than in controls (Pmilrinone, esmolol and vasopressin decreased cardiac injury compared with vasopressin alone. © 2015 The Acta Anaesthesiologica Scandinavica Foundation.

    To investigate the protective effect of oral fluid resuscitation on cardiac function in severe burn rabbits. One hundred and fifty rabbits were randomly divided into normal control group (NC group, n = 6, without treatment), burn group (B group, n = 42, without fluid therapy), immediate oral fluid resuscitation group (C group, n = 42), delayed oral fluid resuscitation group (D group, n = 30) and delayed and rapid oral fluid resuscitation group (E group, n = 30). The rabbits in B, C, D, E groups were subjected to 40% TBSA full-thickness burn, then were treated with fluid therapy immediately after burn (C group), at 6 hour after burn (D, E groups). The myocardial mechanics parameters including mean arterial pressure (MAP), left ventricular systolic pressure (LVSP), left ventricular end diastolic pressure (LVEDP), LV +/- dp/dt max were observed at 2, 6, 8, 12, 24, 36 and 48 post burn hour (PBH). Urine output was also examined. The level of LVSP, LV +/- dp/dt max in B roup were significantly lower than those in NC group. The level of LVSP, LV +/- dp/dt max in the C and E group were singnificantly increased during 24 hour after burn. The level of LV + dp/dt max and LV-dp/dt max in C group peaked at 8 PBH (892 +/- 116 kPa/s) and at 6PBH (724 +/- 149 kPa/s) respectively. The levels of LV +/- dp/dt max, LVSP in D group at each time point were similar to B group (P > 0.05). Both the levels of LV +/- dp/dt max in E group peaked at 8 PBH. The level of LVEDP was no obvious difference between B and other groups at each time point (P > 0.05). The changes of MAP and urine output on 24 PBH in each group were similar to above indices. Effective oral fluid therapy in severe burn rabbits during 24 hours after burn can ameliorate myocardial mechanics parameters. The amount of fluid resuscitation can be estimated according to relevant formula for delayed fluid resuscitation in burn rabbits.

    Full Text Available Asha R Aggarwal, Iqbal Khan Department of Medical Education, Northampton General Hospital, Northampton, UK Objectives: In the UK, cardiopulmonary resuscitation (CPR should be undertaken in the event of cardiac arrest unless a patient has a “Do Not Attempt CPR” document. Doctors have a legal duty to discuss CPR with patients or inform them that CPR would be futile. In this study, final-year medical students were interviewed about their experiences of resuscitation on the wards and of observing conversations about resuscitation status to explore whether they would be equipped to have an informed discussion about resuscitation in the future. Methods: Twenty final-year medical students from two medical schools were interviewed about their experiences on the wards. Interviews were transcribed verbatim, and thematic analysis was undertaken.Results: Students who had witnessed CPR on the wards found that aspects of it were distressing. A significant minority had never seen resuscitation status being discussed with a patient. No students reported seeing a difficult conversation. Half of the students interviewed reported being turned away from difficult conversations by clinicians. Only two of the twenty students would feel comfortable raising the issue of resuscitation with a patient. Conclusion: It is vital that doctors are comfortable talking to patients about resuscitation. Given the increasing importance of this aspect of communication, it should be considered for inclusion in the formal communication skills teaching during medical school.

    We have previously demonstrated that the administration of recombinant human interleukin-11 (rhIL-11) during resuscitation improves the blood pressure in a rodent model of hemorrhagic shock. The purpose of this study was to determine whether the effects of rhIL-11 could be reproduced in a large animal model and to elucidate the impact of rhIL-11 administration on the intravascular volume status and the degree of third space fluid loss after resuscitation. A 40% blood volume hemorrhage was induced in swine (n = 45, weight of 25-35 kg) followed by a 1-h shock period and resuscitation with 0.9% sodium chloride (three times the shed blood volume). The animals were randomized to receive sham hemorrhage (group I, sham); sham hemorrhage and 50 microg/kg rhIL-11 (group II, sham + IL-11); no drug (group III, saline); or 50 microg/kg rhIL-11 (group IV, IL-11). Blood and urine samples were obtained and analyzed at baseline, at the end of hemorrhaging, and thereafter once every hour. The pleural and peritoneal effusions were precisely quantified by using clinically accepted criteria. The mean arterial pressure (MAP) was higher postresuscitation (PR) in groups I, II, and IV (71.4 +/- 7.5 mmHg, 71.0 +/- 8.9 mmHg, and 72.9 +/- 12.3 mmHg, respectively) than in group III (59.9 +/- 10.9 mmHg), and the cardiac output of PR was higher in group IV (3.46 +/- 0.56 L/min) than in group III (2.99 +/- 0.62 L/min; P < 0.01). The difference in MAP between groups I and II became statistically significant at 40 min after rhIL-11 injection and such a difference persisted for 90 min. After resuscitation, the urine output was higher, and the urine specific gravity and third space fluid loss were lower in group IV (1434 +/- 325 mL and 1.0035, 82 +/- 21 mL) than in group III (958 +/- 390 mL and 1.0053, 125 +/- 32 mL; P < 0.05). In a porcine model of hemorrhagic shock, the administration of rhIL-11 at the start of resuscitation significantly improved the cardiac output and blood pressure. This

    Training in the modern form of cardiopulmonary resuscitation (CPR) started in Singapore in 1983. For the first 15 years, the expansion of training programmes was mainly owing to the interest of a few individuals. Public training in the skill was minimal. In an area of medical care where the greatest opportunity for benefit lies in employing core resuscitation skills in the prehospital environment, very little was being done to address such a need. In 1998, a group of physicians, working together with the Ministry of Health, set up the National Resuscitation Council (NRC). Over the years, the NRC has created national guidelines on resuscitation and reviewed them at five-yearly intervals. Provider training manuals are now available for most programmes. The NRC has set up an active accreditation system for monitoring and maintaining standards of life support training. This has led to a large increase in the number of training centres, as well as recognition and adoption of the council's guidelines in the country. The NRC has also actively promoted the use of bystander CPR through community-based programmes, resulting in a rise in the number of certified providers. Improving the chain of survival, through active community-based training programmes, will likely lead to more lives being saved from sudden cardiac arrest.

    To compare the "Bellows on Sternum Resuscitation" (BSR) device that permits simultaneous compression and ventilation by one rescuer with two person cardiopulmonary resuscitation (CPR) with bag-valve-mask (BVM) ventilation in a single blind crossover study performed in the laboratory setting. Tidal volume and compression depth were recorded continuously during 12-min CPR sessions with the BSR device and two person CPR. Six CPR instructors performed a total of 1,894 ventilations and 10,532 compressions in 3 separate 12-min sessions. Mean tidal volume (MTV) and compression rate (CR) with the BSR device differed significantly from CPR with the BVM group (1242 mL vs. 1065 mL, respectively, p = 0.0018 and 63.2 compressions per minute (cpm) vs. 81.3 cpm, respectively, p = 0.0076). Error in compression depth (ECD) rate of 9.78% was observed with the BSR device compared to 8.49% with BMV CPR (p = 0.1815). Error rate was significantly greater during the second half of CPR sessions for both BSR and BVM groups. It is concluded that one-person CPR with the BSR device is equivalent to two-person CPR with BVM in all measured parameters except for CR. Both groups exhibited greater error rate in CPR performance in the latter half of 12-min CPR sessions.

    Secondary intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are closely related to fluid resuscitation. IAH causes major deterioration of the cardiac function by affecting preload, contractility and afterload. The aim of this review is to discuss the different interactions between IAH, ACS and resuscitation, and to explore a new hypothesis with regard to damage control resuscitation, permissive hypotension and global increased permeability syndrome. Review of the relevant literature via PubMed search. The recognition of the association between the development of ACS and resuscitation urged the need for new approach in traumatic shock management. Over a decade after wide spread application of damage control surgery damage control resuscitation was developed. DCR differs from previous resuscitation approaches by attempting an earlier and more aggressive correction of coagulopathy, as well as metabolic derangements like acidosis and hypothermia, often referred to as the 'deadly triad' or the 'bloody vicious cycle'. Permissive hypotension involves keeping the blood pressure low enough to avoid exacerbating uncontrolled haemorrhage while maintaining perfusion to vital end organs. The potential detrimental mechanisms of early, aggressive crystalloid resuscitation have been described. Limitation of fluid intake by using colloids, hypertonic saline (HTS) or hyperoncotic albumin solutions have been associated with favourable effects. HTS allows not only for rapid restoration of circulating intravascular volume with less administered fluid, but also attenuates post-injury oedema at the microcirculatory level and may improve microvascular perfusion. Capillary leak represents the maladaptive, often excessive, and undesirable loss of fluid and electrolytes with or without protein into the interstitium that generates oedema. The global increased permeability syndrome (GIPS) has been articulated in patients with persistent systemic inflammation failing

    To develop a Latin American Consensus about Pediatric Cardiopulmonary Resuscitation. To clarify, reinforce, and adapt some specific recommendations for pediatric patients and to stimulate the implementation of these recommendations in clinical practice. Expert consensus recommendations with Delphi methodology. Latin American countries. Experts in pediatric cardiopulmonary resuscitation from 19 Latin American countries. Delphi methodology for expert consensus. The goal was to reach consensus with all the participating experts for every recommendation. An agreement of at least 80% of the participating experts had to exist in order to deliver a recommendation. Two Delphi voting rounds were sent out electronically. The experts were asked to score between 1 and 9 their level of agreement for each recommendation. The score was then classified into three groups: strong agreement (score 7-9), moderate agreement (score 4-6), and disagreement (score 1-3). Nineteen experts from 19 countries participated in both voting rounds and in the whole process of drafting the recommendations. Sixteen recommendations about organization of cardiopulmonary resuscitation, prevention, basic resuscitation, advanced resuscitation, and postresuscitation measures were approved. Ten of them had a consensus of 100%. Four of them were agreed by all the participants except one (94.7% consensus). One recommendation was agreed by all except two experts (89.4%), and finally, one was agreed by all except three experts (84.2%). All the recommendations reached a level of agreement. This consensus adapts 16 international recommendations to Latin America in order to improve the practice of cardiopulmonary resuscitation in children. Studies should be conducted to analyze the effectiveness of the implementation of these recommendations.

    Full Text Available This study was conducted to determine the efficacy of hypertonic saline solution (HSS along with antibiotic (ceftiofur HCl and non-steroidal anti-inflammatory drug (ketoprofen in the treatment of haemorrhagic septicaemia in buffaloes. For this purpose, 50 buffaloes suffering from haemorrhagic septicaemia were randomly divided in two equal groups A and B. Group A served as control and was treated with ceftiofur HCl (IM and ketoprofen (IV @ 6 and 2 mg/Kg BW, respectively, for five days. Buffaloes of group B were administered with rapid intravenous infusion of hypertonic saline solution (7.5% NaCl @ 4 ml/Kg BW once in combination with ceftiofur HCl and ketoprofen. Animals were monitored for 24 hours after initiation of treatment. Clinical parameters, serum electrolytes, plasma volume and survival index were recorded at different intervals after treatment. Survival rate (80% in group B was significantly higher (P<0.05 than 48% in group A. The heart rate and respiration rate recovered more effectively in the buffaloes administered with treatment protocol B. Plasma volume was 98% which was almost normal within 24 hours after the infusion of hypertonic saline solution to the animals of group B. It was concluded from the study that hypertonic saline solution as an adjunct to antibiotic and a non-steroidal anti-inflammatory drug more efficiently improved respiration and heart rates and effectively restored plasma volume in resuscitating the buffaloes from haemorrhagic septicaemia than the conventional treatment.

    Inadequate resuscitation leads to death or brain injury. Recent recommendations for resuscitation team training to complement knowledge and skills training highlighted the need for development of an effective team resuscitation training session. This study aimed to evaluate and revise an interprofessional team training session which addressed roles and performance during provision of paediatric resuscitation, through incorporation of real-time, real team simulated training episodes. This study was conducted applying the principles of action research. Two cycles of data collection, evaluation and refinement of a 30-40 minute resuscitation training session for doctors and nurses occurred. Doctors and nurses made up 4 groups of training session participants. Their responses to the training were evaluated through thematic analysis of rich qualitative data gathered in focus groups held immediately after each training session. Major themes included the importance of realism, teamwork, and reflective learning. Findings informed important training session changes. These included; committed in-situ training; team diversity; realistic resources; role flexibility, definition and leadership; increased debriefing time and the addition of a team goal. In conclusion, incorporation of interprofessional resuscitation training which addresses team roles and responsibilities into standard medical and nursing training will enhance preparedness for participation in paediatric resuscitation.

    The effect of teaching crisis resource management skills on the resuscitation performance of pediatric residents is unknown. The primary objective of this pilot study was to determine if teaching crisis resource management to residents leads to improved clinical and crisis resource management performance in simulated pediatric resuscitation scenarios. A prospective, randomized control pilot study. Simulation facility at tertiary pediatric hospital. Junior pediatric residents. Junior pediatric residents were randomized to 1 hour of crisis resource management instruction or no additional training. Time to predetermined resuscitation tasks was noted in simulated resuscitation scenarios immediately after intervention and again 3 months post intervention. Crisis resource management skills were evaluated using the Ottawa Global Rating Scale. Fifteen junior residents participated in the study, of which seven in the intervention group. The intervention crisis resource management group placed monitor leads 24.6 seconds earlier (p = 0.02), placed an IV 47.1 seconds sooner (p = 0.04), called for help 50.4 seconds faster (p = 0.03), and checked for a pulse after noticing a rhythm change 84.9 seconds quicker (p = 0.01). There was no statistically significant difference in time to initiation of cardiopulmonary resuscitation (p = 0.264). The intervention group had overall crisis resource management performance scores 1.15 points higher (Ottawa Global Rating Scale [out of 7]) (p = 0.02). Three months later, these differences between the groups persisted. A 1-hour crisis resource management teaching session improved time to critical initial steps of pediatric resuscitation and crisis resource management performance as measured by the Ottawa Global Rating Scale. The control group did not develop these crisis resource management skills over 3 months of standard training indicating that obtaining these skills requires specific education. Larger studies of crisis resource education are

    Effective resuscitation requires the integration of several cognitive, technical, and behavioral skills. Because resuscitation is performed by teams of health care professionals, these individuals must be able to work together in a coordinated and efficient manner, making teamwork a critical skill for care of patients in distress. Despite the importance of teamwork in health care, little consensus exists as to what it is, how it can most effectively be learned, and how it should be assessed. This article reviews current knowledge on the measurement, training, and importance of teamwork in pediatric resuscitation.

    To determine how training in pediatric cardiopulmonary resuscitation is provided in the Iberoamerican countries. Survey. Latin America, Spain, and Portugal. Experts in pediatric cardiopulmonary resuscitation education. A questionnaire was sent to experts in pediatric cardiopulmonary resuscitation training in 21 countries in Latin America, Spain, and Portugal; we received 15 replies. Pediatric cardiopulmonary resuscitation training is not included in medical undergraduate or nursing training in any of these countries and pediatric residents receive systematic cardiopulmonary resuscitation training in only four countries. Basic pediatric life support courses, pediatric advanced life support courses, and pediatric cardiopulmonary resuscitation instructors courses are given in 13 of 15, 14 of 15, and 11 of 15 respondent countries, respectively. Course duration and the number of hours of practical training were variable: basic life support, 5 hrs (range, 4-8 hrs); practical training, 4 hrs (range, 2-5 hrs); advanced life support, 18 hrs (range, 10-30 hrs); and practical training, 14 hrs (range, 5-18 hrs). Only nine countries (60%) had a national group that organized pediatric cardiopulmonary resuscitation training. Thirteen countries (86.6%) had fewer than five centers offering pediatric cardiopulmonary resuscitation training. Respondents considered the main obstacles to the expansion of training in pediatric cardiopulmonary resuscitation to be the shortage of instructors (28.5%), students' lack of financial resources (21.4%), and deficiencies in educational organization (21.4%). Pediatric cardiopulmonary resuscitation training is not uniform across the majority of Iberoamerican countries, with poor organization and little institutional involvement. National groups should be created in each country to plan and coordinate pediatric cardiopulmonary resuscitation training and to coordinate with other Iberoamerican countries.

  20. A novel fluid resuscitation strategy modulates pulmonary transcription factor activation in a murine model of hemorrhagic shock

    2010-01-01

    Full Text Available INTRODUCTION: Combining the hemodynamic and immune benefits of hypertonic saline with the anti-inflammatory effects of the phosphodiesterase inhibitor pentoxifylline (HSPTX as a hemorrhagic shock resuscitation strategy reduces lung injury when compared with the effects of Ringer's lactate (RL. We hypothesized that HSPTX exerts its anti-inflammatory effects by interfering with nuclear factor kappa B/cAMP response element-binding protein (NF-κB-CREB competition for the coactivator CREB-binding protein (CBP in lung tissue, thus affecting pro-inflammatory mediator production. METHODS: Male Sprague-Dawley rats underwent 60 minutes of hemorrhagic shock to reach a mean arterial blood pressure of 35 mmHg followed by resuscitation with either RL or HSPTX (7.5% HS + 25 mg/kg PTX. After four hours, lung samples were collected. NF-κB activation was assessed by measuring the levels of phosphorylated cytoplasmic inhibitor of kappa B (I-κB and nuclear NF-κB p65 by western blot. NF-κB and CREB DNA-binding activity were measured by electrophoretic mobility shift assay (EMSA. Competition between NF-κB and CREB for the coactivator CBP was determined by immunoprecipitation. Interleukin-8 (IL-8 levels in the lung were measured by ELISA. RESULTS: RL resuscitation produced significantly higher levels of lung IL-8 levels, I-κB phosphorylation, p65 phosphorylation, and NF-κB DNA binding compared with HSPTX. NF-κB-CBP-binding activity was similar in both groups, whereas CREB-CBP-binding activity was significantly increased with HSPTX. CREB-DNA binding-activity increased to a greater level with HSPTX compared with RL. DISCUSSION: HSPTX decreases lung inflammation following hemorrhagic shock compared with conventional resuscitation using RL through attenuation of NF-κB signaling and increased CREB-DNA binding activity.

    In a prospective, randomized, placebo-controlled, double-blind trial we tested the hypothesis that naloxone given during cardiopulmonary resuscitation (CPR) enhances cerebral and myocardial blood flow. Twenty-one anesthetized, normoventilated pigs were instrumented for measurements of right atrial and aortic pressures, and regional organ blood flow (radiolabeled microspheres). After 5 min of untreated fibrillatory arrest, CPR was commenced using a pneumatic chest compressor/ventilator. With onset of CPR, an i.v. bolus of 40 micrograms/kg b.w. of epinephrine was given, followed by an infusion of 0.4 micrograms/kg per min. After 5 min of CPR, either naloxone, 10 mg/kg b.w. (group N, n = 11) or normal saline (group S, n = 10) was given i.v. Prior to, and after 1, 15, and 30 min of CPR, hemodynamic and blood flow measurements were obtained. After 30 min of CPR, mean arterial pressure was significantly higher in group N (26 +/- 5 vs. 13 +/- 3 mmHg, P CPR.

    Although ATP-MgCl2 improves hepatocellular function in a nonheparinized model of trauma-hemorrhage and crystalloid resuscitation, it remains unknown whether the beneficial effects of this agent are due to downregulation of the release of the inflammatory cytokines, tumor necrosis factor (TNF), and interleukin-6 (IL-6) under those conditions. To study this, rats underwent a 5-cm laparotomy (i.e., trauma induced) and were bled to and maintained at a mean arterial pressure of 40 mm Hg until 40% of maximum bleedout volume was returned in the form of Ringer's lactate (RL). The animals were then resuscitated with four times the volume of shed blood with RL over 60 min. ATP-MgCl2 (50 mumoles/kg body weight each) or an equivalent volume of normal saline was infused intravenously for 95 min. This infusion was started during the last 15 min of RL resuscitation. Plasma levels of TNF and IL-6 were measured at 1.5 hr after the completion of resuscitation by cytokine-dependent cellular assays. Hepatic blood flow was determined by in vivo indocyanine green clearance (corrected by hepatic extraction ratio for indocyanine green), radioactive microspheres, and [3H]-galactose clearance techniques. The results indicate that the levels of circulating TNF and IL-6 increased significantly in the hemorrhaged-resuscitated animals. ATP-MgCl2 treatment, however, markedly decreased the synthesis and/or release of these cytokines to levels similar to the sham group. The markedly decreased hepatic blood flow (as determined by three different methods) and hepatic extraction ratio for indocyanine green were also restored by ATP-MgCl2 treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available Abstract Background Advanced resuscitation skills training is an important and enjoyable part of medical training, but requires small group instruction to ensure active participation of all students. Increases in student numbers have made this increasingly difficult to achieve. Methods A single-blind randomised controlled trial of peer-led vs. expert-led resuscitation training was performed using a group of sixth-year medical students as peer instructors. The expert instructors were a senior and a middle grade doctor, and a nurse who is an Advanced Life Support (ALS Instructor. A power calculation showed that the trial would have a greater than 90% chance of rejecting the null hypothesis (that expert-led groups performed 20% better than peer-led groups if that were the true situation. Secondary outcome measures were the proportion of High Pass grades in each groups and safety incidents. The peer instructors designed and delivered their own course material. To ensure safety, the peer-led groups used modified defibrillators that could deliver only low-energy shocks. Blinded assessment was conducted using an Objective Structured Clinical Examination (OSCE. The checklist items were based on International Liaison Committee on Resuscitation (ILCOR guidelines using Ebel standard-setting methods that emphasised patient and staff safety and clinical effectiveness. The results were analysed using Exact methods, chi-squared and t-test. Results A total of 132 students were randomised: 58 into the expert-led group, 74 into the peer-led group. 57/58 (98% of students from the expert-led group achieved a Pass compared to 72/74 (97% from the peer-led group: Exact statistics confirmed that it was very unlikely (p = 0.0001 that the expert-led group was 20% better than the peer-led group.

    The American Heart Association (AHA) guidelines for cardiopulmonary resuscitation (CPR) and emergency cardiovascular care (ECC) were changed in 2005. There were some key changes in the recommendations for pediatric basic and advanced life support, and neonatal resuscitation. The key changes included: emphasis on effective compressions (push hard, push fast, allow full chest recoil and minimize interruptions in compressions), a single compression-ventilation ratio (30:2) CPR for all groups of ages (except neonate), confirmation of effective ventilations, medication given and defibrillator charged without interruption of CPR, not recommended to routine tracheal suction the vigorous meconium-stained baby in newborn resuscitation, etc. We illustrate the major key changes and hope everyone is well trained to perform high quality CPR.

    Published results of dose-response effects of adrenergic drugs (epinephrine [E]) vary so much between studies because of differences in animal models and duration of ischemia before drug administration. In this investigation the effects of different doses of E on coronary perfusion pressure (CPP), left ventricular myocardial blood flow (MBF) and resuscitation success were compared during closed-chest cardiopulmonary resuscitation (CPR) after a 4-minute period of ventricular fibrillation in 28 pigs. MBF was measured during normal sinus rhythm using tracer microspheres. After 4 minutes of ventricular fibrillation CPR was performed with the use of a pneumatic piston compressor. After 4 minutes of mechanical measures only, the animals were randomly allocated into four groups of seven, receiving 0.015, 0.030, 0.045, and 0.090 mg/kg E intravenously respectively. MBF measurements were started 45 seconds after E administration; hemodynamic measurements after 90 seconds. Four minutes after the first administration, the same E dose was given before defibrillation. The CPP of animals given 0.015, 0.030, 0.045 and 0.090 mg/kg E were as follows: 16.3 +/- 6.1, 25.6 +/- 5.8, 33.2 +/- 8.4 and 30.4 +/- 6.3 mm Hg. The left ventricular MBF values were: 14 +/- 9, 27 +/- 11, 43 +/- 6, 46 +/- 10 mL/min/100 g. The differences between the groups receiving 0.015 and 0.045 mg/kg and between the groups receiving 0.015 mg/kg and 0.090 mg/kg were statistically significant (P less than .05). Resuscitation success was 14.3%, 42.9%, 100% and 86.7% respectively. A significant difference in resuscitation success was found only between 0.015 mg/kg and 0.045 mg/kg E.(ABSTRACT TRUNCATED AT 250 WORDS)

    To examine the effectiveness of a "cardiopulmonary resuscitation song" in improving the basic life support skills of secondary school students. This pre-test/post-test control design study enrolled secondary school students from two middle schools randomly chosen in Córdoba, Andalucia, Spain. The study included 608 teenagers. A random sample of 87 students in the intervention group and 35 in the control group, aged 12-14 years were selected. The intervention included a cardiopulmonary resuscitation song and video. A questionnaire was conducted at three-time points: pre-intervention, one month and eight months post-intervention. On global knowledge of cardiopulmonary resuscitation, there were no significant differences between the intervention group and the control group in the trial pre-intervention and at the month post-intervention. However, at 8 months there were significant differences with a p-value = 0.000 (intervention group, 95% CI: 6.39 to 7.13 vs. control group, 95% CI: 4.75 to 5.92), F(1,120)=16.644, p=0.000). In addition, significant differences about students' basic life support knowledge about chest compressions at eight months post-intervention (F(1,120)=15.561, p=0.000) were found. Our study showed that incorporating the song component in the cardiopulmonary resuscitation teaching increased its effectiveness and the ability to remember the cardiopulmonary resuscitation algorithm. Our study highlights the need for different methods in the cardiopulmonary resuscitation teaching to facilitate knowledge retention and increase the number of positive outcomes after sudden cardiac arrest.

  8. Family presence at resuscitation attempts.

    Jaques, Helen

    UK resuscitation guidelines suggest that parents and carers should be allowed to be present during a resuscitation attempt in hospital but no guidance is available regarding family presence when resuscitation takes place out of hospital. A new research study has suggested that relatives who were offered the opportunity to witness resuscitation were less likely to develop symptoms of post-traumatic stress disorder than those who were not given the chance. This article summarises the results of this study and provides an expert commentary on its conclusions.

    The effect of saline iontophoresis on skin barrier function and irritation was investigated in four ethnic groups (Caucasians, Hispanics, Blacks and Asians). Forty healthy human volunteers were recruited according to specific entry criteria. Ten subjects, five males and five females, were assigned to each ethnic group. Skin barrier function was examined after 4 hours of saline iontophoresis at a current density of 0.2 mA/cm(2) on a 6.5 cm(2) area in terms of the measured responses: transepidermal water loss (TEWL), skin capacitance, skin temperature and visual scores. There were significant differences in TEWL among the ethnic groups prior to patch application. TEWL at baseline in ethnic groups was in the rank order: Caucasian>Asian>Hispanic>Black. Iontophoresis was generally well tolerated, and skin barrier function was not irreversibly affected by iontophoresis in any group. There was no significant skin temperature change, compared to baseline, in any ethnic groups at any observation point. Edema was not observed. At patch removal, the erythema score was elevated in comparison to baseline in all ethnic groups; erythema resolved within 24 hours. Thus, saline iontophoresis produced reversible changes in skin barrier function and irritation in healthy human subjects.

    The purpose of this study is to compare the cardiopulmonary resuscitation (CPR) team dynamics and performance between a conventional simulation training group and a script-based training group. This was a prospective randomised controlled trial of educational intervention for CPR team training. Fourteen teams, each consisting of five members, were recruited. The conventional group (C) received training using a didactic lecture and simulation with debriefing, while the script group (S) received training using a resuscitation script. The team activity was evaluated with checklists both before and after 1 week of training. The videotaped simulated resuscitation events were compared in terms of team dynamics and performance aspects. Both groups showed significantly higher leadership scores after training (C: 58.2 ± 9.2 vs. 67.2 ± 9.5, p=0.007; S: 57.9 ± 8.1 vs. 65.4 ± 12.1, p=0.034). However, there were no significant improvements in performance scores in either group after training. There were no differences in the score improvement after training between the two groups in dynamics (C: 9.1 ± 12.6 vs. S: 7.4 ± 13.7, p=0.715), performance (C: 5.5 ± 11.4 vs. S: 4.7 ± 9.6, p=0.838) and total scores (C: 14.6 ± 20.1 vs. S: 12.2 ± 19.5, p=0.726). Script-based CPR team training resulted in comparable improvements in team dynamics scores compared with conventional simulation training. Resuscitation scripts may be used as an adjunct for CPR team training.

    We investigated the effects of dyadic training on medical students' resuscitation performance during cardiopulmonary resuscitation (CPR) training.We provided students with a 2-hour training session on CPR for simulated cardiac arrest. Student teams were split into double groups (Dyad training groups: Groups A and B) or Single Groups. All groups received 2 CPR simulation rounds. CPR simulation training began with peer demonstration for Group A, and peer observation for Group B. Then the 2 groups switched roles. Single Groups completed CPR simulation without peer observation or demonstration. Teams were then evaluated based on leadership, teamwork, and team member skills.Group B had the highest first simulation round scores overall (P = 0.004) and in teamwork (P = 0.001) and team member skills (P = 0.031). Group B also had the highest second simulation round scores overall (P training groups with those of Single Groups in overall scores, leadership scores, teamwork scores, and team member scores. In the second simulation, Dyad training groups scored higher in overall scores (P = 0.002), leadership scores (P = 0.044), teamwork scores (P = 0.005), and team member scores (P = 0.008). Dyad training groups also displayed higher improvement in overall scores (P = 0.010) and team member scores (P = 0.022).Dyad training was effective for CPR training. Both peer observation and demonstration for peers in dyad training can improve student resuscitation performance.

    Utstein-style guidelines contribute to improved public health internationally by providing a structured framework with which to compare emergency medical services systems. Advances in resuscitation science, new insights into important predictors of outcome from out-of-hospital cardiac arrest, and lessons learned from methodological research prompted this review and update of the 2004 Utstein guidelines. Representatives of the International Liaison Committee on Resuscitation developed an updated Utstein reporting framework iteratively by meeting face to face, by teleconference, and by Web survey during 2012 through 2014. Herein are recommendations for reporting out-of-hospital cardiac arrest. Data elements were grouped by system factors, dispatch/recognition, patient variables, resuscitation/postresuscitation processes, and outcomes. Elements were classified as core or supplemental using a modified Delphi process primarily based on respondents' assessment of the evidence-based importance of capturing those elements, tempered by the challenges to collect them. New or modified elements reflected consensus on the need to account for emergency medical services system factors, increasing availability of automated external defibrillators, data collection processes, epidemiology trends, increasing use of dispatcher-assisted cardiopulmonary resuscitation, emerging field treatments, postresuscitation care, prognostication tools, and trends in organ recovery. A standard reporting template is recommended to promote standardized reporting. This template facilitates reporting of the bystander-witnessed, shockable rhythm as a measure of emergency medical services system efficacy and all emergency medical services system-treated arrests as a measure of system effectiveness. Several additional important subgroups are identified that enable an estimate of the specific contribution of rhythm and bystander actions that are key determinants of outcome.

    Manual ventilation in the delivery room is provided with devices such as self-inflating bags (SIBs), flow-inflating bags, and T-piece resuscitators. To compare the effect of type of manual ventilation device on overall response to resuscitation among preterm neonates born at Apgar score. Secondary outcomes were incidence of air leaks, need for chest compressions/epinephrine, need for intubation, and surfactant use. We identified 294 resuscitations requiring ventilation. SIB was used for 135 neonates, and T-piece was used for 159 neonates. There was no significant difference between the 1-min and 5-min Apgar scores between SIB and T-piece (P = .77 and P = .11, respectively), nor were there significant differences in secondary outcomes. The rate of rise of Apgar score was higher, by 0.47, with T-piece, compared to SIB (95% CI 0.08-0.87, P = .02). Although some manikin studies favor T-piece for providing reliable and consistent pressures, our experience did not indicate significant differences in effectiveness of resuscitation between the T-piece and SIB in preterm resuscitations.

    Human serum albumin (HSA) is used as a plasma expander; however, albumin is readily eliminated from the intravascular space. The objective of this study was to establish the effects of various-sized polymerized HSAs (PolyHSAs) during small-volume resuscitation from hemorrhagic shock on systemic parameters, microvascular hemodynamics, and functional capillary density in the hamster window chamber model. Polymerized HSA size was controlled by varying the cross-link density (ie, molar ratio of glutaraldehyde to HSA). Hemorrhage was induced by controlled arterial bleeding of 50% of the animal's blood volume (BV), and hypovolemic shock was maintained for 1 hour. Resuscitation was implemented in 2 phases, first, by infusion of 3.5% of the BV of hypertonic saline (7.5% NaCl) then followed by infusion of 10% of the BV of each PolyHSA. Resuscitation provided rapid recovery of blood pressure, blood gas parameters, and microvascular perfusion. Polymerized HSA at a glutaraldehyde-to-HSA molar ratio of 60:1 (PolyHSA(60:1)) provided superior recovery of blood pressure, microvascular blood flow, and functional capillary density, and acid-base balance, with sustained volume expansion in relation to the volume infused. The high molecular weight of PolyHSA(60:1) increased the hydrodynamic radius and solution viscosity. Pharmacokinetic analysis of PolyHSA(60:1) indicates reduced clearance and increased circulatory half-life compared with monomeric HSA and other PolyHSA formulations. In conclusion, HSA molecular size and solution viscosity affect central hemodynamics, microvascular blood flow, volume expansion, and circulation persistence during small-volume resuscitation from hemorrhagic shock. In addition, PolyHSA can be an alternative to HSA in pathophysiological situations with compromised vascular permeability. Copyright © 2012 Elsevier Inc. All rights reserved.

    Out-of-hospital cardiac arrest (OHCA) is associated with a poor prognosis. As comorbidity and frailty increase with age; ethical dilemmas may arise when OHCA occur in the very old. We aimed to investigate mortality, neurological outcome and post resuscitation care in octogenarians (≥80) to assess whether resuscitation and post resuscitation care should be avoided. During 2007-2011 consecutive OHCA-patients were attended by the physician-based Emergency Medical Services-system in Copenhagen. Pre-hospital data based on Utstein-criteria, and data on post resuscitation care were collected. Primary outcome was successful resuscitation; secondary endpoints were 30-day mortality and neurological outcome (Cerebral Performance Category (CPC)). 2509 OHCA-patients with attempted resuscitation were recorded, 22% (n=558) were octogenarians/nonagenarians. 166 (30% of all octogenarians with resuscitation attempted) octogenarians were successfully resuscitated compared to 830 (43% with resuscitation attempted) patients <80 years. 30-day mortality in octogenarians was significantly higher after adjustment for prognostic factors (HR=1.61 CI: 1.22-2.13, p<0.001). Octogenarians received fewer coronary angiographies (CAG) (14 vs. 37%, p<0.001), and had lower odds of receiving CAG by multivariate logistic regression (OR: 0.19, CI: 0.08-0.44, p<0.001). A favorable neurological outcome (CPC 1/2) in survivors to discharge was found in 70% (n=26) of octogenarians compared to 86% (n=317, p=0.03) in the younger patients. OHCA in octogenarians was associated with a significantly higher mortality rate after adjustment for prognostic factors. However, the majority of octogenarian survivors were discharged with a favorable neurological outcome. Withholding resuscitation and post resuscitation care in octogenarians does not seem justified.

Due to the frequent need for resuscitation at birth, it is vital to have evidence-based care guidelines and to provide effective neonatal resuscitation training. Every five years, the International Liaison Committee on Resuscitation (ILCOR reviews the science of neonatal resuscitation. In the US, the American Heart Association (AHA develops treatment guidelines based on the ILCOR science review, and the Neonatal Resuscitation Program (NRP translates the AHA guidelines into an educational curriculum. In this report, we review recent advances in neonatal resuscitation training and practice. We begin with a review of the new 7th edition NRP training curriculum. Then, we examine key changes to the 2015 AHA neonatal resuscitation guidelines. The four components of the NRP curriculum reviewed here include eSim®, Performance Skills Stations, Integrated Skills Station, and Simulation and Debriefing. The key changes to the AHA neonatal resuscitation guidelines reviewed include initial steps of newborn care, positive-pressure ventilation, endotracheal intubation and use of laryngeal mask, chest compressions, medications, resuscitation of preterm newborns, and ethics and end-of-life care. We hope this report provides a succinct review of recent advances in neonatal resuscitation.

    Full Text Available Introduction: Respiratory failure is a common problem in emergency medicine (EM and critical care medicine (CCM. However, little is known about the resuscitation of critically ill patients prior to emergency endotracheal intubation (EETI. Our aim was to describe the resuscitation practices of EM and CCM physicians prior to EETI. Methods: A cross-sectional survey was developed and tested for content validity and retest reliability by members of the Canadian Critical Care Trials Group. The questionnaire was distributed to all EM and CCM physician members of three national organizations. Using three clinical scenarios (trauma, pneumonia, congestive heart failure, we assessed physician preferences for use and types of fluid and vasopressor medication in pre-EETI resuscitation of critically ill patients. Results: In total, 1,758 physicians were surveyed (response rate 50.2%, 882/1,758. Overall, physicians would perform pre-EETI resuscitation using either fluids or vasopressors in 54% (1,193/2,203 of cases. Most physicians would “always/often” administer intravenous fluid pre-EETI in the three clinical scenarios (81%, 1,484/1,830. Crystalloids were the most common fluid physicians would “always/often” administer in congestive heart failure (EM 43%; CCM 44%, pneumonia (EM 97%; CCM 95% and trauma (EM 96%; CCM 96%. Pre-EETI resuscitation using vasopressors was uncommon (4.9%. Training in CCM was associated with performing pre-EETI resuscitation (odds ratio, 2.20; 95% CI, [1.44-3.36], p<0.001. Conclusion: Pre-EETI resuscitation is common among Canadian EM and CCM physicians. Most physicians use crystalloids pre-EETI as a resuscitation fluid, while few would give vasopressors. Physicians with CCM training were more likely to perform pre-EETI resuscitation.

    To determine whether variables in physicians' backgrounds influenced their decision to forego resuscitating a patient they did not previously know. Questionnaire survey of a convenience sample of 204 physicians working in the departments of internal medicine, anaesthesiology and cardiology in 11 hospitals in Israel. Twenty per cent of the participants had elected to forego resuscitating a patient they did not previously know without additional consultation. Physicians who had more frequently elected to forego resuscitation had practised medicine for more than 5 years (p=0.013), estimated the number of resuscitations they had performed as being higher (p=0.009), and perceived their experience in resuscitation as sufficient (p=0.001). The variable that predicted the outcome of always performing resuscitation in the logistic regression model was less than 5 years of experience in medicine (OR 0.227, 95% CI 0.065 to 0.793; p=0.02). Physicians' level of experience may affect the probability of a patient's receiving resuscitation, whereas the physicians' personal beliefs and values did not seem to affect this outcome.

  1. Resuscitating the Baby after Shoulder Dystocia

    Full Text Available Background. To propose hypovolemic shock as a possible explanation for the failure to resuscitate some babies after shoulder dystocia and to suggest a change in clinical practice. Case Presentation. Two cases are presented in which severe shoulder dystocia was resolved within five minutes. Both babies were born without a heartbeat. Despite standard resuscitation by expert neonatologists, no heartbeat was obtained until volume resuscitation was started, at 25 minutes in the first case and 11 minutes in the second. After volume resuscitation circulation was restored, there was profound brain damage and the babies died. Conclusion. Unsuspected hypovolemic shock may explain some cases of failed resuscitation after shoulder dystocia. This may require a change in clinical practice. Rather than immediately clamping the cord after the baby is delivered, it is proposed that (1 the obstetrician delay cord clamping to allow autotransfusion of the baby from the placenta and (2 the neonatal resuscitators give volume much sooner.

    Polyethylene glycol-20k (PEG-20k) is highly effective for low-volume resuscitation (LVR) by increasing tolerance to the low-volume state. In our rodent shock model, PEG-20k increased survival and expanded the "golden hour" 16-fold compared to saline. The molecular mechanism is largely attributed to normalizations in cell and tissue fluid shifts after low-flow ischemia resulting in efficient microvascular exchange. The objective of this study was to evaluate PEG-20k as an LVR solution for hemorrhagic shock in a preclinical model. Anesthetized male Yorkshire pigs (30-40 kg) were hemorrhaged to a mean arterial pressure (MAP) of 35 to 40 mm Hg. Once lactate reached 7 mmol/L, either saline (n = 5) or 10% PEG-20k (n = 5) was rapidly infused at 10% calculated blood volume. The primary outcome was LVR time, defined by the time from LVR administration to the time when lactate again reached 7 mmol/L. Other outcomes measured included MAP, heart rate, cardiac output, mixed venous oxygen saturation, splanchnic blood flow, and hemoglobin. Relative to saline, PEG-20k given after controlled hemorrhage increased LVR time by 16-fold, a conservative estimate given that the lactate never rose after LVR in the PEG-20k group. Survival was 80% for PEG-20k LVR compared to 0% for the saline controls (p the intravascular compartment. In a preclinical model of controlled hemorrhagic shock, PEG-20k-based LVR solution increased tolerance to the shock state 16-fold compared to saline. Polyethylene glycol-20k is a superior crystalloid for LVR that may increase safe transport times in the prehospital setting and find use in hospital emergency departments and operating rooms for patients awaiting volume replacement or normalization of cell, tissue, and compartment fluid volumes.

    Resuscitation guidelines endorse unconscious and normally breathing out-of-hospital victims to be placed in the recovery position to secure airway patency, but recently a debate has been opened as to whether the recovery position threatens the cardiac arrest victim's safety assessment and delays the start of cardiopulmonary resuscitation. To compare the assessment of the victim's breathing arrest while placed in the recovery position versus maintaining an open airway with the continuous head tilt and chin lift technique to know whether the recovery position delays the cardiac arrest victim's assessment and the start of cardiopulmonary resuscitation. Basic life support-trained university students were randomly divided into two groups: one received a standardized cardiopulmonary resuscitation refresher course including the recovery position and the other received a modified cardiopulmonary resuscitation course using continuous head tilt and chin lift for unconscious and spontaneously breathing patients. A human simulation test to evaluate the victim's breathing assessment was performed a week later. In total, 59 participants with an average age of 21.9 years were included. Only 14 of 27 (51.85%) students in the recovery position group versus 23 of 28 (82.14%) in the head tilt and chin lift group p=0.006 (OR 6.571) detected breathing arrest within 2min. The recovery position hindered breathing assessment, delayed breathing arrest identification and the initiation of cardiac compressions, and significantly increased the likelihood of not starting cardiopulmonary resuscitation when compared to the results shown when the continuous head tilt and chin lift technique was used.

    This chapter aims to provide an up-to-date review of the science and clinical practice pertaining to neurologic injury after successful cardiopulmonary resuscitation. The past two decades have seen a major shift in the science and practice of cardiopulmonary resuscitation, with a major emphasis on postresuscitation neurologic care. This chapter provides a nuanced and thoughtful historic and bench-to-bedside overview of the neurologic aspects of cardiopulmonary resuscitation. A particular emphasis is made on the anatomy and pathophysiology of hypoxic-ischemic encephalopathy, up-to-date management of survivors of cardiopulmonary resuscitation, and a careful discussion on neurologic outcome prediction. Guidance to practice evidence-based clinical care when able and thoughtful, pragmatic suggestions for care where evidence is lacking are also provided. This chapter serves as both a useful clinical guide and an updated, thorough, and state-of-the-art reference on the topic for advanced students and experienced practitioners in the field. © 2017 Elsevier B.V.

    Advanced cardiovascular life support guidelines exist, yet there are variations in clinical practice. Our study aims to describe the utilization of medications during resuscitation from in-hospital cardiopulmonary arrest. A retrospective review of patients who suffered a cardiopulmonary arrest from May 2008 to June 2014 was performed. Clinical and resuscitation data, including timing and dose of medications used, were extracted from the electronic medical record and comparisons made. A total of 94 patients were included in the study. Patients were divided into different groups based on the medication combination used during resuscitation: (1) epinephrine; (2) epinephrine and bicarbonate; (3) epinephrine, bicarbonate, and calcium; (4) epinephrine, bicarbonate, and epinephrine drip; and (5) epinephrine, bicarbonate, calcium, and epinephrine drip. No difference in baseline demographics or clinical data was present, apart from history of dementia and the use of calcium channel blockers. The number of medications given was correlated with resuscitation duration (Spearman's rank correlation = 0.50, p resuscitation durations compared to that of the other groups (p resuscitation efforts for in-hospital cardiopulmonary arrests. Increased duration and mortality rates were found in those resuscitations compared with epinephrine alone, likely due to the longer resuscitation duration in the former groups.

    To predict the likelihood that an inpatient who experiences cardiopulmonary arrest and undergoes cardiopulmonary resuscitation survives to discharge with good neurologic function or with mild deficits (Cerebral Performance Category score = 1). Classification and Regression Trees were used to develop branching algorithms that optimize the ability of a series of tests to correctly classify patients into two or more groups. Data from 2007 to 2008 (n = 38,092) were used to develop candidate Classification and Regression Trees models to predict the outcome of inpatient cardiopulmonary resuscitation episodes and data from 2009 (n = 14,435) to evaluate the accuracy of the models and judge the degree of over fitting. Both supervised and unsupervised approaches to model development were used. 366 hospitals participating in the Get With the Guidelines-Resuscitation registry. Adult inpatients experiencing an index episode of cardiopulmonary arrest and undergoing cardiopulmonary resuscitation in the hospital. The five candidate models had between 8 and 21 nodes and an area under the receiver operating characteristic curve from 0.718 to 0.766 in the derivation group and from 0.683 to 0.746 in the validation group. One of the supervised models had 14 nodes and classified 27.9% of patients as very unlikely to survive neurologically intact or with mild deficits (Tree models that predict survival to discharge with good neurologic function or with mild deficits following in-hospital cardiopulmonary arrest. Models like this can assist physicians and patients who are considering do-not-resuscitate orders.

    To evaluate the effectiveness of a strategy for teaching neonatal resuscitation on the cognitive knowledge of health professionals who attend deliveries in Ghana, West Africa. Train-the-trainer model was used to train health professionals at 2-3 day workshops from 2003 to 2007. Obstetric Anticipatory Care and Basic Neonatal Care modules were taught as part of Neonatal Resuscitation Training package. American Neonatal Resuscitation Program was adapted to the clinical role of participants and local resources. Cognitive knowledge was evaluated by written pre- and post-training tests. The median pre-training and post-training scores were 38% and 71% for midwives, 43% and 81% for nurses, 52% and 90% for nurse anaesthetists, and 62% and 98% for physicians. All groups of the 271 professionals (18 nurse anaesthetists, 55 nurses, 68 physicians, and 130 midwives) who completed the course showed significant improvement (pfacilities were less likely to achieve passing post-test scores than midwives at secondary and tertiary facilities [35/53 vs. 24/26 vs. 45/51 (p=0.004)] respectively. Evidence-based neonatal resuscitation training adapted to local resources significantly improved cognitive knowledge of all groups of health professionals. Further modification of training for midwives working at primary level health facilities and incorporation of neonatal resuscitation in continuing education and professional training programs are recommended.

  8. The clinical nurse specialist as resuscitation process manager.

    The purpose of this article was to describe the history and leadership dimensions of the role of resuscitation process manager and provide specific examples of how this role is implemented at a Midwest medical center. In 1992, a medical center in the Midwest needed a nurse to manage resuscitation care. This role designation meant that this nurse became central to all quality improvement efforts in resuscitation care. The role expanded as clinical resuscitation guidelines were updated and as the medical center grew. The role became known as the critical care clinical nurse specialist as resuscitation process manager. This clinical care nurse specialist was called a manager, but she had no direct line authority, so she accomplished her objectives by forming a multitude of collaborative networks. Based on a framework by Finkelman, the manager role incorporated specific leadership abilities in quality improvement: (1) coordination of medical center-wide resuscitation, (2) use of interprofessional teams, (3) integration of evidence into practice, and (4) staff coaching to develop leadership. The manager coordinates resuscitation care with the goals of prevention of arrests if possible, efficient and effective implementation of resuscitation protocols, high quality of patient and family support during and after the resuscitation event, and creation or revision of resuscitation policies for in-hospital and for ambulatory care areas. The manager designs a comprehensive set of meaningful and measurable process and outcome indicators with input from interprofessional teams. The manager engages staff in learning, reflecting on care given, and using the evidence base for resuscitation care. Finally, the manager role is a balance between leading quality improvement efforts and coaching staff to implement and sustain these quality improvement initiatives. Revisions to clinical guidelines for resuscitation care since the 1990s have resulted in medical centers developing improved

    The Japan Resuscitation Council (JRC) Guidelines 2010 for neonatal resuscitation introduced continuous positive airway pressure (CPAP) in delivery room. The present study evaluated the effect of CPAP for pulmonary air leak at term birth. This retrospective single-centre study used the data of term neonates who were born without major congenital anomalies at our centre between 2008 and 2009, and between 2011 and 2012. Resuscitation according to the JRC Guidelines 2010. We examined the association between the JRC Guidelines 2010, CPAP by face mask and pulmonary air leak. A total of 5038 infants were analysed. The frequency of CPAP by face mask increased after the update of the JRC Guidelines in 2010 (1.7% vs 11.1%; pneonates (37 weeks: adjusted OR (aOR) 4.37; 95% CI 1.40 to 17.45; 38 weeks: aOR 2.80; 95% CI 1.04 to 8.91), but this association disappeared while adjusting for face mask CPAP additionally (37 weeks: aOR 1.90; 95% CI 0.47 to 8.71; 38 weeks: aOR 1.66; 95% CI 0.54 to 5.77). Following the update of the JRC guidelines on neonatal resuscitation, we observed an increased use of CPAP via face mask, which was associated with a higher prevalence of pulmonary air leak in early-term neonates in our centre.

    Adjustment of adrenaline (epinephrine) dosage according to cardiac arrest (CA) duration, rather than administering the same dose, may theoretically improve resuscitation outcomes. We evaluated variable effects of high-dose adrenaline (HDA) relative to standard-dose adrenaline (SDA) on resuscitation outcomes according to CA duration. Twenty-eight male domestic pigs were randomised to the following 4 groups according to the dosage of adrenaline (SDA 0.02 mg/kg vs. HDA 0.2mg/kg) and duration of CA before beginning cardiopulmonary resuscitation (CPR): 6 min SDA, 6 min HDA, 13 min SDA, or 13 min HDA. After the predetermined duration of untreated ventricular fibrillation, CPR was provided. All animals in the 6 min SDA, 6 min HDA, and 13 min HDA groups were successfully resuscitated, while only 4 of 7 pigs in the 13 min SDA group were successfully resuscitated (p=0.043). HDA groups showed higher right atrial pressure, more frequent ventricular ectopic beats, higher blood glucose, higher troponin-I, and more severe metabolic acidosis than SDA groups. Animals of 13 min groups showed more severe metabolic acidosis and higher troponin-I than animals of 6 min groups. All successfully resuscitated animals, except two animals in the 13 min HDA group, survived for 7 days (p=0.121). Neurologic deficit score was not affected by the dose of adrenaline. HDA showed benefit in achieving restoration of spontaneous circulation in 13 min CA, when compared with 6 min CA. However, this benefit did not translate into improved long-term survival or neurologic outcome. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    The ability of health care providers to work together is essential for favourable outcomes in neonatal resuscitation, but perceptions of such teamwork have rarely been studied in low-income settings. Neonatal resuscitation is a proven intervention for reducing neonatal mortality globally, but the long-term effects of clinical training for this skill need further attention. Having an understanding of barriers to teamwork among nurse midwives can contribute to the sustainability of improved clinical practice. To explore nurse midwives' perceptions of teamwork when caring for newborns in need of resuscitation. Nurse midwives from a tertiary-level government hospital in Nepal participated in five focus groups of between 4 and 11 participants each. Qualitative Content Analysis was used for analysis. One overarching theme emerged: looking for comprehensive guidelines and shared responsibilities in neonatal resuscitation to avoid personal blame and learn from mistakes. Participants discussed the need for protocols relating to neonatal resuscitation and the importance of shared medical responsibility, and the importance of the presence of a strong and transparent leadership. The call for clear and comprehensive protocols relating to neonatal resuscitation corresponded with previous research from different contexts. Nurse midwives working at a maternity health care facility in Nepal discussed the benefits and challenges of teamwork in neonatal resuscitation. The findings suggest potential benefits can be made from clarifying guidelines and responsibilities in neonatal resuscitation. Furthermore, a structured process to deal with clinical incidents must be considered. Management must be involved in all processes. Copyright © 2017 Australian College of Midwives.

    High risk deliveries are usually associated with increased neonatal mortality and morbidity. Neonatal resuscitation can appreciably affect the outcome in these types of deliveries. Presence of personnel trained in basic neonatal resuscitation at the time of delivery can play an important role in reducing perinatal complications in neonates at risk. The study was carried out to evaluate the effects of newborn resuscitation on neonatal outcome in high risk deliveries. Methods: This descriptive case series was carried out at the Department of Obstetrics and Gynecology, Jinnah Hospital, Lahore. Ninety consecutive high risk deliveries were included and attended by paediatricians trained in newborn resuscitation. Babies delivered by elective Caesarean section, normal spontaneous vaginal deliveries and still births were excluded. Neonatal resuscitation was performed in babies who failed to initiate breathing in the first minute after birth. Data was analyzed using SPSS-16.0. Results: A total of 90 high risk deliveries were included in the study. Emergency caesarean section was the mode of delivery in 94.4% (n=85) cases and spontaneous vaginal delivery in 5.6% (n=5). Preterm pregnancy was the major high risk factor. Newborn resuscitation was required in 37.8% (n=34) of all high risk deliveries (p=0.013). All the new-borns who required resuscitation survived. Conclusion: New-born resuscitation is required in high risk pregnancies and personnel trained in newborn resuscitation should be available at the time of delivery. (author)

    In contrast to the resuscitation guidelines of children and adults, guidelines on neonatal resuscitation recommend synchronized 90 chest compressions with 30 manual inflations (3:1) per minute in newborn infants. The study aimed to determine if chest compression with asynchronous ventilation improves the recovery of bradycardic asphyxiated newborn piglets compared to 3:1 Compression:Ventilation cardiopulmonary resuscitation (CPR). Term newborn piglets (n=8/group) were anesthetized, intubated, instrumented and exposed to 45-min normocapnic hypoxia followed by asphyxia. Protocolized resuscitation was initiated when heart rate decreased to 25% of baseline. Piglets were randomized to receive resuscitation with either 3:1 compressions to ventilations (3:1C:V CPR group) or chest compressions with asynchronous ventilations (CCaV) or sham. Continuous respiratory parameters (Respironics NM3(®)), cardiac output, mean systemic and pulmonary artery pressures, and regional blood flows were measured. Piglets in 3:1C:V CPR and CCaV CPR groups had similar time to return of spontaneous circulation, survival rates, hemodynamic and respiratory parameters during CPR. The systemic and regional hemodynamic recovery in the subsequent 4h was similar in both groups and significantly lower compared to sham-operated piglets. Newborn piglets resuscitated by CCaV had similar return of spontaneous circulation, survival, and hemodynamic recovery compared to those piglets resuscitated by 3:1 Compression:Ventilation ratio.

    The subjects were 88 cases of non-traumatic CPA excluding those with primary brain disease. The subjects were divided into 4 groups according to the duration of cardiac arrest: Group A (less than 15 minutes, 2 cases), Group B (15-30 minutes, 11 cases), Group C (more than 30 minutes, 40 cases), Group D (no resuscitation after cardiac arrest, 35 cases). All cases in Group A were observed to be clear consciousness after resuscitation. Not only the functional outcome but also the survivals rates were poorer as the duration of cardiac arrest increased in Groups B and C compared to Group A. The mortality rate was 85% or higher for cardiac arrest of 15 minutes or longer. Brain edema after resuscitation was examined by head CT in the basal-ganglia and thalamus regions, and in the corticomedullary junction of the cerebrum. In the cases of short duration of cardiac arrest, the basal-ganglia and thalamus regions, and the corticomedullary junction were clearly visible on CT. On the other hand, these areas were poorly or not visible (marked brain edema) in the cases of longer duration of cardiac arrest. The borders of the basal-ganglia and thalamus regions, and the corticomedullary junction were not obscured in any of the cases in Group A. However, the borders of these regions were poorly visible or not visible more frequently as the duration of cardiac arrest increased. In particular, the corticomedullary junction was not visible more frequently after cardiac arrest of long duration. Brain edema is caused and intensified by prolongation of hypoxia, but it is also reported to be caused by external cardiac massage, which increases the intracranial pressure. This was also suggested by the more notable brain edema in the corticomedullary junction than in the basal-ganglia and thalamus regions. These findings of brain edema appeared on head CT within 4 hours after CPR. Findings suggestive of vascular occlusion were also obtained. (K.H.)

    The Guidelines place emphasis on high-quality cardiopulmonary resuscitation (CPR). This study aims to measure the impact of post-resuscitation feedback on the quality of CPR as performed by ambulance personnel. Two ambulances are dispatched for suspected cardiac arrest. The crew (driver and paramedic) of the first arriving ambulance is responsible for the quality of CPR. The crew of the second ambulance establishes an intravenous access and supports the first crew. All resuscitation attempts led by the ambulance crew of the study region were reviewed by two research paramedics and structured feedback was given based on defibrillator recording with impedance signal. A 12-months period before introduction of post-resuscitation feedback was compared with a 19-months period after introduction of feedback, excluding a six months run-in interval. Quality parameters were chest compression fraction (CCF), chest compression rate, longest peri-shock pause and longest non-shock pause. In the pre-feedback period 55 cases were analyzed and 69 cases in the feedback period. Median CCF improved significantly in the feedback period (79% vs 86%, presuscitation feedback improves the quality of resuscitation, significantly increasing CCF and decreasing the duration of longest non-shock pauses.

    2018-02-01

    This review summarizes the evolution of trauma resuscitation from a one-size-fits-all approach to one tailored to patient physiology. The most dramatic change is in the management of actively bleeding patients, with a balanced blood product-based resuscitation approach (avoiding crystalloids) and surgery focused on hemorrhage control, not definitive care. When hemostasis has been achieved, definitive resuscitation to restore organ perfusion is initiated. This approach is associated with decreased mortality, reduced duration of stay, improved coagulation profile, and reduced crystalloid/vasopressor use. This article focuses on the tools and methods used for trauma resuscitation in the acute phase of trauma care. Copyright © 2017 Elsevier Inc. All rights reserved.

    Effective cardiopulmonary resuscitation saves lives. Health professionals who care for acutely unwell children need to be prepared to care for a child in arrest. Hospitals must ensure that their staff have the knowledge, confidence and ability to respond to a child in cardiac arrest. RESUS4KIDS is a programme designed to teach paediatric resuscitation to health care professionals who care for acutely unwell children. The programme is delivered in two components: an e-learning component for pre-learning, followed by a short, practical, face-to-face course that is taught using the round-the-table teaching approach. Round-the-table teaching is a novel, evidence-based small group teaching approach designed to teach paediatric resuscitation skills and knowledge. Round-the-table teaching uses a structured approach to managing a collapsed child, and ensures that each participant has the opportunity to practise the essential resuscitation skills of airway manoeuvres, bag mask ventilation and cardiac compressions. Round-the-table teaching is an engaging, non-threatening approach to delivering interdisciplinary paediatric resuscitation education. The methodology ensures that all participants have the opportunity to practise each of the different essential skills associated with the Danger, Response, Send for help, Airway, Breathing, Circulation, Defibrillation or rhythm recognition (DRSABCD) approach to the collapsed child. Round-the-table teaching is based on evidence-based small group teaching methods.

    To determine whether presenting delivery room management options as defaults influences decisions to resuscitate extremely premature infants. Adult volunteers recruited from the world wide web were randomised to receive either resuscitation or comfort care as the delivery room management default option for a hypothetical delivery of a 23-week gestation infant. Participants were required to check a box to opt out of the default. The primary outcome measure was the proportion of respondents electing resuscitation. Data were analysed using χ(2) tests and multivariate logistic regression. Participants who were told the delivery room management default option was resuscitation were more likely to opt for resuscitation (OR 6.54 95% CI 3.85 to 11.11, pmanipulation. Further, this effect may operate in ways that a decision maker is not aware of and this raises questions of patient autonomy. Presenting delivery room options for extremely premature infants as defaults may compromise autonomous decision-making.

    All rescuers trained or not, should provide chest compressions to victims of cardiac arrest. The aim should be to push to a depth of at least 5 cm at a rate of at least 100 compressions per minute, to allow full chest recoil, and to minimise interruptions in chest compressions. Trained rescuers should also provide ventilations with a compression-ventilation ratio of 30:2. ELECTRICAL THERAPIES: Much greater emphasis on minimising the duration of the pre-shock and post-shock pauses; the continuation of compressions during charging of the defibrillator is recommended. Further development of AED programmes is encouraged. ADULT ADVANCED LIFE SUPPORT: Increased emphasis on high-quality chest compressions throughout any ALS intervention paused briefly only to enable specific interventions. Removal of the recommendation for a pre-specified period of cardiopulmonary resuscitation before out-of-hospital defibrillation following cardiac arrest unwitnessed by the EMS. The role of precordial thump is de-emphasized. Delivery of drugs via a tracheal tube is no longer recommended, drugs should be given by the intraosseous (IO) route. Atropine is no longer recommended for routine use in asystole or pulseless electrical activity. Reduced emphasis on early tracheal intubation unless achieved by highly skilled individuals with minimal interruptions in chest compressions. Increased emphasis on the use of capnography. Recognition of potential harm caused by hyperoxaemia. Revision of the recommendation of glucose control. Use of therapeutic hypothermia to include comatose survivors of cardiac arrest associated initially with shockable rhythms, as well as non-shockable rhythms, with a lower level of evidence acknowledged for the latter.

    Out-of-hospital cardiac arrest has high rates of morbidity and mortality, and a growing body of evidence is redefining our approach to the resuscitation of these high-risk patients. Team-focused cardiopulmonary resuscitation (TFCPR), most commonly deployed and described by prehospital care providers, is a focused approach to cardiac arrest care that emphasizes early defibrillation and high-quality, minimally interrupted chest compressions while de-emphasizing endotracheal intubation and intravenous drug administration. TFCPR is associated with statistically significant increases in survival to hospital admission, survival to hospital discharge, and survival with good neurologic outcome; however, the adoption of similar streamlined resuscitation approaches by emergency physicians has not been widely reported. In the absence of a deliberately streamlined approach, such as TFCPR, other advanced therapies and procedures that have not shown similar survival benefit may be prioritized at the expense of simpler evidence-based interventions. This review examines the current literature on cardiac arrest resuscitation. The recent prehospital success of TFCPR is highlighted, including the associated improvements in multiple patient-centered outcomes. The adaptability of TFCPR to the emergency department (ED) setting is also discussed in detail. Finally, we discuss advanced interventions frequently performed during ED cardiac arrest resuscitation that may interfere with early defibrillation and effective high-quality chest compressions. TFCPR has been associated with improved patient outcomes in the prehospital setting. The data are less compelling for other commonly used advanced resuscitation tools and procedures. Emergency physicians should consider incorporating the TFCPR approach into ED cardiac arrest resuscitation to optimize delivery of those interventions most associated with improved outcomes.

    Full Text Available Abstract Background The International Liaison Committee on Resuscitation (ILCOR now recommends therapeutic hypothermia (TH (33°C for 12-24 hours as soon as possible for patients who remain comatose after resuscitation from shockable rhythm in out-of-hospital cardiac arrest and that it be considered for non shockable rhythms. The optimal timing of TH is still uncertain. Laboratory data have suggested that there is significantly decreased neurological injury if cooling is initiated during CPR. In addition, peri-arrest cooling may increase the rate of successful defibrillation. This study aims to determine whether paramedic cooling during CPR improves outcome compared standard treatment in patients who are being resuscitated from out-of-hospital cardiac arrest. Methods/Design This paper describes the methodology for a definitive multi-centre, randomised, controlled trial of paramedic cooling during CPR compared with standard treatment. Paramedic cooling during CPR will be achieved using a rapid infusion of large volume (20-40 mL/kg to a maximum of 2 litres ice-cold (4°C normal saline. The primary outcome measure is survival at hospital discharge. Secondary outcome measures are rates of return of spontaneous circulation, rate of survival to hospital admission, temperature on arrival at hospital, and 12 month quality of life of survivors. Discussion This trial will test the effect of the administration of ice cold saline during CPR on survival outcomes. If this simple treatment is found to improve outcomes, it will have generalisability to prehospital services globally. Trial Registration ClinicalTrials.gov: NCT01172678

    The Royal College of Anaesthetists, the Royal College of Physicians, the Intensive Care Society and the Resuscitation Council (UK) have published new resuscitation standards. The document provides advice to UK healthcare organisations, resuscitation committees and resuscitation officers on all aspects of the resuscitation service. It includes sections on resuscitation training, resuscitation equipment, the cardiac arrest team, cardiac arrest prevention, patient transfer, post-resuscitation care, audit and research. The document makes several recommendations. Healthcare institutions should have, or be represented on, a resuscitation committee that is responsible for all resuscitation issues. Every institution should have at least one resuscitation officer responsible for teaching and conducting training in resuscitation techniques. Staff with patient contact should be given regular resuscitation training appropriate to their expected abilities and roles. Clinical staff should receive regular training in the recognition of patients at risk of cardiopulmonary arrest and the measures required for the prevention of cardiopulmonary arrest. Healthcare institutions admitting acutely ill patients should have a resuscitation team, or its equivalent, available at all times. Clear guidelines should be available indicating how and when to call for the resuscitation team. Cardiopulmonary arrest should be managed according to current national guidelines. Resuscitation equipment should be available throughout the institution for clinical use and for training. The practice of resuscitation should be audited to maintain and improve standards of care. A do not attempt resuscitation (DNAR) policy should be compiled, communicated to relevant members of staff, used and audited regularly. Funding must be provided to support an effective resuscitation service.

    Full Text Available Purpose: In this study, we aimed to determine the success rate of cardiopulmonary resuscitation performed in the patients with diagnosis of cardiac arrest, and demographic characteristics of these patients. Material and Methods: The patients admitted to Adana Numune Education and Research Hospital, Department of Emergency Medicine between 01.01.2011 and 31.12.2012, and who underwent cardiopulmonary resuscitation were included to this study planned as retrospectively. The age, gender, status of judicial cases, causes and time of cardiac arrest, first observed arrest rhythm, the diseases prior to the arrest, means of arrival to emergency department, duration of cardiopulmonary resuscitation, results of cardiopulmonary resuscitation, the name of the hospitalised clinic, the existence of the operation, and outcome of the patients who underwent cardiopulmonary resuscitation in accordance with current advanced life support protocols were recorded in standard data entry form. Results: A total of 290 patients with completely accessible data were included to the study. Most of these patients were men (65.2%. The mean ages were 61 ± 19 years for men, 67 ± 14 years for women (p = 0.018. The most common diagnosis were ischemic heart disease and heart failure according to the analysis of the patient's medical history. 92 patients (31.7% were brought to the emergency department after death, and all of these patients were unsuccessful following to cardiopulmonary resuscitation. 198 patients (68.3% had cardiac arrest in the emergency department, and we determined that cardiopulmonary resuscitation application of 102 patients were successful. The most common causes of cardiac arrest were myocardial infarction and heart failure. Mostly first observed rhythm in the monitor was asystole. The response rate of cardiopulmonary resuscitation in patients with ventricular fibrillation and ventricular tachycardia was higher. Most patients were hospitalised to the

    In the Yarkon-Taninim groundwater basin, the karstic Judea Group aquifer contains groundwater of high quality. However, in the western wells of the Kefar Uriya area located in the foothills of the Judea Mountains, brackish groundwater was locally encountered. The salinity of this water is caused presumably by two end members designated as the 'Hazerim' and 'Lakhish' water types. The Hazerim type represents surface water percolating through a highly fractured thin chalky limestone formation overlying the Judea Group aquifer. The salinity of the water derives conjointly from several sources such as leachates from rendzina and grumosols, dissolution of caliche crusts which contain evaporites and of rock debris from the surrounding formations. This surface water percolates downwards into the aquifer through a funnel- or chimney-like mechanism. This local salinization mechanism supercedes another regional process caused by the Lakhish waters. These are essentially diluted brines originating from deep formations in the western parts of the Coastal Plain. The study results show that salinization is not caused by the thick chalky beds of the Senonian Mt Scopus Group overlying the Judea Group aquifer, as traditionally considered but prevalently by aqueous leachates from soils and rock debris. The conceptual qualitative hydrogeological model of the salinization as demonstrated in this study, is supported by a quantitative hydrological model presented in another paper in this volume.

    To compare gain in knowledge and skills of neonatal resuscitation using tele-education instruction vs conventional classroom teaching. This randomized controlled trial was conducted in the tele-education facility of a tertiary care center. In-service staff nurses were randomized to receive training by tele-education instruction (TI, n=26) or classroom teaching (CT, n=22) method from two neonatology instructors using a standardized teaching module on neonatal resuscitation. Gain in knowledge and skill scores of neonatal resuscitation were measured using objective assessment methods. Age, educational qualification and professional experience of the participants in two groups were comparable. Pre-training mean knowledge scores were higher in TI group (8.3±1.7 vs 6.6±1.4, P=0.004). However, skill scores were comparable in the two groups (11.7±3 vs 10.3±2.9, P=0.13). Training resulted in a significant and comparable gain in knowledge scores (4.2±2.2 vs 5.3±1.7; P=0.06) and skills scores (4.5±3.3 vs 5.0±3.1, P=0.62) in both the groups. The post-training knowledge scores (TI: 12.5±1.7 vs CT: 12.0±1.7, P=0.37) and the post-training skill scores (TI: 16.0±0.5 vs CT: 15.6±2.5, P=0.55) were comparable in the two groups. However, the post-training scores, adjusted for baseline knowledge scores, were statistically higher in the in-person group compared with the telemedicine group (knowledge: 12.46±0.03 vs 12.16±0.01, P=0.00; skills: 15.6±2.5 vs 16.0±2.8, P=0.00). The quantum of lower scores in the telemedicine group was only 2% for knowledge and 6% for skills. This difference was felt to be of only marginal importance. Satisfaction scores among trainees and instructors were comparable in the two groups. Tele-education offers a feasible and effective alternative to conventional training in neonatal resuscitation among health-care providers.

    AIM: To assess current knowledge and training in the management of contrast media reactions and cardiopulmonary resuscitation within a radiology department. MATERIALS AND METHODS: The standard of knowledge about the management of contrast media reactions and cardiopulmonary resuscitation among radiologists, radiographers and nurses were audited using a two-section questionnaire. Our results were compared against nationally accepted standards. Repeat audits were undertaken over a 28-month period. Three full audit cycles were completed. RESULTS: The initial audit confirmed that although a voluntary training programme was in place, knowledge of cardiopulmonary resuscitation techniques were below acceptable levels (set at 70%) for all staff members. The mean score for radiologists was 50%. Immediate changes instituted included retraining courses, the distribution of standard guidelines and the composition and distribution of two separate information handouts. Initial improvements were complemented by new wallcharts, which were distributed throughout the department, a series of lectures on management of contrast reactions and regular reviews with feedback to staff. In the third and final audit all staff groups had surpassed the required standard. CONCLUSION: Knowledge of contrast media reactions and resuscitation needs constant updating. Revision of skills requires a prescriptive programme; visual display of advice is a constant reminder. It is our contention all radiology departmental staff should consider it a personal duty to maintain their resuscitation skills at appropriate standards. O'Neill, J.M., McBride, K.D.(2001).

    2014-12-01

    We reviewed Greek mythology to accumulate tales of resuscitation and we explored whether these tales could be viewed as indirect evidence that ancient Greeks considered resuscitation strategies similar to those currently used. Three compendia of Greek mythology: The Routledge Handbook of Greek Mythology, The Greek Myths by Robert Graves, and Greek Mythology by Ioannis Kakridis were used to find potentially relevant narratives. Thirteen myths that may suggest resuscitation (including 1 case of autoresuscitation) were identified. Methods to attempt mythological resuscitation included use of hands (which may correlate with basic life support procedures), a kiss on the mouth (similar to mouth-to-mouth resuscitation), application of burning torches (which might recall contemporary use of external defibrillators), and administration of drugs (a possible analogy to advanced life support procedures). A careful assessment of relevant myths demonstrated that interpretations other than medical might be more credible. Although several narratives of Greek mythology might suggest modern resuscitation techniques, they do not clearly indicate that ancient Greeks presaged scientific methods of resuscitation. Nevertheless, these elegant tales reflect humankind's optimism that a dying human might be restored to life if the appropriate procedures were implemented. Without this optimism, scientific improvement in the field of resuscitation might not have been achieved.

    Although researchers in several countries have investigated patients' points of view regarding cardiopulmonary resuscitation, there has been no research investigating this issue in Greece. The present study aimed at identifying the attitude of older Greek patients regarding cardiopulmonary resuscitation. One basic questionnaire consisting of 34 questions was used in order to identify patients' opinions regarding cardiopulmonary resuscitation in five different hospitals from June to November 2011. In total, 300 questionnaires were collected. Although patients' knowledge regarding cardiopulmonary resuscitation was poor, most of them would like to be resuscitated in case they suffered an in-hospital cardiac arrest. Also, they believe that they should have the right to accept or refuse treatment. However, the legal and sociocultural norms in Greece do not support patients' choice for the decision to refuse resuscitation. The influence of several factors, such as their general health status or the underlying pathology, could lead patients to give a "do not attempt resuscitation" order. The attitudes of older Greek patients regarding resuscitation are not different from others', whereas the legal and sociocultural norms in Greece do not support patient choice in end-of-life decisions, namely the decision to refuse resuscitation. We advocate the introduction of advanced directives, as well as the establishment and implementation of specific legislation regarding the ethics of resuscitation in Greece. © 2013 Japan Geriatrics Society.

    Magnesium sulphate administration is recommended for foetal neuroprotection in pregnant women at imminent risk of early preterm birth. To evaluate the relationship between intrapartum magnesium sulphate for foetal neuroprotection and delivery room resuscitation of preterm infants less 32 weeks. A prospective observational study was conducted on preterm infants less 32 weeks exposed to magnesium sulphate for neuroprotection, and a comparison made with another historic group immediately before starting this treatment. Cases in both groups that had not reached lung maturity with corticosteroids were rejected. The rates of resuscitation, morbidity and mortality for each of the groups were analysed and compared. There was a total of 107 preterm, with 56 exposed to magnesium sulphate. Rate of advanced resuscitation were similar between the two groups. There were no other differences in mortality, invasive mechanical ventilation, time to first stool, and other comorbidities. Intrapartum magnesium sulphate for foetal neuroprotection was not associated with an increased need for intensive delivery room resuscitation and other morbidities in these cohorts of less than 32 weeks preterm infants.

    Examine the relationship between delivery room resuscitation intensity and mortality, morbidities and resource use in late preterm infants. Retrospective cohort study of inborn infants born at 33 to 36 weeks' gestation and admitted to Canadian neonatal intensive care units during 2010 to 2013. The 13 619 infants were grouped according to delivery room resuscitation intensity: no or minimal resuscitation (64.5%); continuous positive airway pressure (10.2%); bag-mask ventilation (21.7%); endotracheal intubation (3.1%); and cardiopulmonary resuscitation (CPR) (0.6%). Overall mortality, early mortality, respiratory distress, pneumothorax, late-onset sepsis and resource use increased with higher intensity resuscitation. Compared with no or minimal resuscitation, intubation and CPR were associated with increased odds of mortality (adjusted odds ratio (95% confidence interval): 50 (20 to 125) and 180 (63 to 518), respectively). Intubation or higher intensity delivery room resuscitation is associated with increased mortality, morbidities and resource use in late preterm infants. Extra intensive care is required for such infants, especially during the first week of life.

    Full Text Available OBJECTIVE: To analyze the early and late results of cardiopulmonary resuscitation in a cardiology hospital and to try to detect prognostic determinants of both short- and long-term survival. METHODS: A series of 557 patients who suffered cardiorespiratory arrest (CRA at the Dante Pazzanese Cardiology Institute over a period of 5 years was analyzed to examine factors predicting successful resuscitation and long-term survival. RESULTS: Ressuscitation maneuvers were tried in 536 patients; 281 patients (52.4% died immediately, and 164 patients (30.6% survived for than 24 hours. The 87 patients who survived for more than 1 month after CRA were compared with nonsurvivors. Coronary disease, cardiomyopathy, and valvular disease had a better prognosis. Primary arrhythmia occurred in 73.5% of the >1-month survivor group and heart failure occurred in 12.6% of this group. In those patients in whom the initial mechanism of CRA was ventricular fibrillation, 33.3% survived for more than 1 month, but of those with ventricular asystole only 4.3% survived. None of the 10 patients with electromechanical dissociation survived. There was worse prognosis in patients included in the extreme age groups (zero to 10 years and 70 years or more. The best results occurred when the cardiac arrest took place in the catheterization laboratories. The worst results occurred in the intensive care unit and the hemodialysis room. CONCLUSION: The results in our series may serve as a helpful guide to physicians with the difficult task of deciding when not to resuscitate or when to stop resuscitation efforts.

    Full Text Available Objective  To compare the effects of routine liquid resuscitation on hemorrhagic shock in uncontrolled and controlled states for exploring the strategy of liquid resuscitation. Methods  Twenty-eight healthy male SD rats were randomly divided into three groups: control (n=8, controlled hemorrhagic shock (CHS, n=10, and uncontrolled hemorrhagic shock (UHS, n=10. In the CHS and UHS groups, the rats were made to bleed from the femoral artery till the blood pressure declined to 30 mmHg within 15 minutes. Thereafter, the roots of the rat tails in the three groups were cut. The trunks of the tails were ligated to stop the bleeding in the control and CHS groups, but it was not ligated in the UHS group, and no treatment was given. Imitating war condition, the animals were divided into three phases: pre-hospital period (30–90 minutes, hospital period (90–150 minutes, and recovery period (150 minutes to 72 hours. The blood pressure was maintained at 60mmHg in the pre-hospital period by transfusion. The bleeding point was ligated in the hospital period, and the blood pressure was maintained at 90mmHg by blood and fluid transfusions. In the recovery period, the observation time was maintained up to 72 hours. The mean arterial pressure (MAP, central venous pressure (CVP, heart function, blood gas analysis, hematocrit, and blood lactic acid were determined. The amount of bleeding, quantity of infusions, and survival time of animals were observed and recorded. Results  Based on the design of the experiment, the MAP of rats in the CHS and UHS groups was maintained at 60mmHg and 90mmHg in the pre-hospital period and hospital period by liquid resuscitation, respectively. There was no significant difference in the MAP and CVP between the CHS and UHS groups. However, the hematocrit of the rats in the UHS group in the pre-hospital period was clearly lower than that in the CHS group. Starting from the pre-hospital period, blood lactic acid content increased

    This study aimed to identify the effects of interprofessional resuscitation skills teaching on medical and nursing students' attitudes, leadership, team-working and performance skills. Year 2 medical and nursing students learned resuscitation skills in uniprofessional or interprofessional settings, prior to undergoing observational ratings of video-recorded leadership, teamwork and skills performance and subsequent focus group interviews. The Readiness for Interprofessional Learning Scale (RIPLS) was administered pre- and post-intervention and again 3-4 months later. There was no significant difference between interprofessional and uniprofessional teams for leadership, team dynamics or resuscitation tasks performance. Gender, previous interprofessional learning experience, professional background and previous leadership experience had no significant effect. Interview analysis showed broad support for interprofessional education (IPE) matched to clinical reality with perceived benefits for teamwork, communication and improved understanding of roles and perspectives. Concerns included inappropriate role adoption, hierarchy issues, professional identity and the timing of IPE episodes. The RIPLS subscales for professional identity and team-working increased significantly post-intervention for interprofessional groups but returned to pre-test levels by 3-4 months. However, interviews showed interprofessional groups retained a 'residual positivity' towards IPE, more so than uniprofessional groups. An intervention based on common, relevant, shared learning outcomes set in a realistic educational context can work with students who have differing levels of previous IPE and skills training experience. Qualitatively, positive attitudes outlast quantitative changes measured using the RIPLS. Further quantitative and qualitative work is required to examine other domains of learning, the timing of interventions and impact on attitudes towards IPE.

    Patients' preferences for cardiopulmonary resuscitation (CPR) relate to their perception about the likelihood of success of the procedure. There is evidence that the lay public largely base their perceptions about CPR on their experience of the portrayal of CPR in the media. The medical profession has generally been critical of the portrayal of CPR on medical drama programmes although there is no recent evidence to support such views. To compare the patient characteristics, cause and success rates of cardiopulmonary resuscitation (CPR) on medical television drama with published resuscitation statistics. Observational study. 88 episodes of television medical drama were reviewed (26 episodes of Casualty, Casualty, 25 episodes of Holby City, 23 episodes of Grey's Anatomy and 14 episodes of ER) screened between July 2008 and April 2009. The patient's age and sex, medical history, presumed cause of arrest, use of CPR and immediate and long term survival rate were recorded. Immediate survival and survival to discharge following CPR. There were a total of 76 cardio-respiratory arrests and 70 resuscitation attempts in the episodes reviewed. The immediate success rate (46%) did not differ significantly from published real life figures (p=0.48). The resuscitation process appeared to follow current guidelines. Survival (or not) to discharge was rarely shown. The average age of patients was 36 years and contrary to reality there was not an age related difference in likely success of CPR in patients less than 65 compared with those 65 and over (p=0.72). The most common cause of cardiac arrest was trauma with only a minor proportion of arrests due to cardio-respiratory causes such as myocardial infarction. Whilst the immediate success rate of CPR in medical television drama does not significantly differ from reality the lack of depiction of poorer medium to long term outcomes may give a falsely high expectation to the lay public. Equally the lay public may perceive that the

    Resuscitation and life support skills training comprises a significant proportion of continuing education programming for health professionals. The purpose of this study was to explore the perceptions and attitudes of certified resuscitation providers toward the retention of resuscitation skills, regular skills updating, and methods for enhancing retention. A mixed-methods, explanatory study design was undertaken utilizing focus groups and an online survey-questionnaire of rural and urban health care providers. Rural providers reported less experience with real codes and lower abilities across a variety of resuscitation areas. Mock codes, practice with an instructor and a team, self-practice with a mannequin, and e-learning were popular methods for skills updating. Aspects of team performance that were felt to influence resuscitation performance included: discrepancies in skill levels, lack of communication, and team leaders not up to date on their skills. Confidence in resuscitation abilities was greatest after one had recently practiced or participated in an update or an effective debriefing session. Lowest confidence was reported when team members did not work well together, there was no clear leader of the resuscitation code, or if team members did not communicate. The study findings highlight the importance of access to update methods for improving providers' confidence and abilities, and the need for emphasis on teamwork training in resuscitation. An eclectic approach combining methods may be the best strategy for addressing the needs of health professionals across various clinical departments and geographic locales.

    2012-01-01

    Recent reviews of burn resuscitation have included the suggestion that "fluid creep" may be influenced by practitioner error. Our center uses a nursing-driven resuscitation protocol that permits titration of fluid based on hourly urine output, including the addition of colloid when patients fail to respond appropriately. The purpose of this study was to examine protocol compliance. We reviewed 140 patients (26 children) with burns of ≥20% TBSA who received protocol-directed resuscitation from 2005 to 2010. We compared each patient's actual hourly fluid infusion with that predicted by the protocol. Sixty-seven patients (48%) completed resuscitation using crystalloid alone, whereas 73 patients required colloid supplementation. Groups did not differ in age, gender, weight, or time from injury to admission. Patients requiring colloid had larger median total burns (33.0 vs 23.5% TBSA) and full-thickness burns (15.5 vs 4.5% TBSA) and more inhalation injuries (60.3 vs 28.4%; P patients had median predicted requirements of 5.4 ml/kg/%TBSA. Crystalloid-only patients required fluid volumes close to Parkland predictions (4.7 ml/kg/%TBSA), whereas patients who received colloid required more fluid than the predicted volume (7.5 ml/kg/%TBSA). However, the hourly difference between the predicted and received fluids was a median of only 1.0% (interquartile range: -6.1 to 11.1%) and did not differ between groups. Pediatric patients had greater calculated differences than adults. Crystalloid patients exhibited higher urine outputs than colloid patients until colloid was started, suggesting that early over-resuscitation did not contribute to fluid creep. Adherence to our protocol for burn shock resuscitation was excellent overall. Fluid creep exhibited by more seriously injured patients was not due to nurses' failure to follow the protocol. This review has illuminated some opportunities for practice improvement, possibly using a computerized decision support system.

    To study advanced trauma life support (ATLS) protocol adherence prospectively in trauma resuscitation and to analyse time management of daily multidisciplinary trauma resuscitation at a level 1 trauma centre, for both moderately and severely injured patients. All victims of severe blunt trauma were consecutively included. Patients with a revised trauma score (RTS) of 12 were resuscitated by a "minor trauma" team and patients with an RTS of less than 12 were resuscitated by a "severe trauma" team. Digital video recordings were used to analyse protocol compliance and time management during initial assessment. From 1 May to 1 September 2003, 193 resuscitations were included. The "minor trauma" team assessed 119 patients, with a mean injury severity score (ISS) of 7 (range 1-45). Overall protocol compliance was 42%, ranging from 0% for thoracic percussion to 93% for thoracic auscultation. The median resuscitation time was 45.9 minutes (range 39.7-55.9). The "severe team" assessed 74 patients, with a mean ISS of 22 (range 1-59). Overall protocol compliance was 53%, ranging from 4% for thoracic percussion to 95% for thoracic auscultation. Resuscitation took 34.8 minutes median (range 21.6-44.1). Results showed the current trauma resuscitation to be ATLS-like, with sometimes very low protocol compliance rates. Timing of secondary survey and radiology and thus time efficiency remains a challenge in all trauma patients. To assess the effect of trauma resuscitation protocols on outcome, protocol adherence needs to be improved.

    A compression-ventilation (C:V) ratio of 30:2 is recommended for adult cardiopulmonary resuscitation (CPR) by the current American Heart Association (AHA) guidelines. However, continuous chest compression (CCC) is an alternative strategy for CPR that minimizes interruption especially when an advanced airway exists. In this study, we investigated the effects of 30:2 mechanical CPR when compared with CCC in combination with regular ventilation in a porcine model. Sixteen male domestic pigs weighing 39±2 kg were utilized. Ventricular fibrillation was induced and untreated for 7 min. The animals were then randomly assigned to receive CCC combined with regular ventilation (CCC group) or 30:2 CPR (VC group). Mechanical chest compression was implemented with a miniaturized mechanical chest compressor. At the same time of beginning of precordial compression, the animals were mechanically ventilated at a rate of 10 breaths-per-minute in the CCC group or with a 30:2 C:V ratio in the VC group. Defibrillation was delivered by a single 150 J shock after 5 min of CPR. If failed to resuscitation, CPR was resumed for 2 min before the next shock. The protocol was stopped if successful resuscitation or at a total of 15 min. The resuscitated animals were observed for 72 h. Coronary perfusion pressure, end-tidal carbon dioxide and carotid blood flow in the VC group were similar to those achieved in the CCC group during CPR. No significant differences were observed in arterial blood gas parameters between two groups at baseline, VF 6 min, CPR 4 min and 30, 120 and 360 min post-resuscitation. Although extravascular lung water index of both groups significantly increased after resuscitation, no distinct difference was found between CCC and VC groups. All animals were successfully resuscitated and survived for 72 h with favorable neurologic outcomes in both groups. However, obviously more numbers of rib fracture were observed in CCC animals in comparison with VC animals. There was no

    The criteria for refraining from cardiopulmonary resuscitation in palliative care cancer patients are based on patients' right to refuse treatment and the duty of the treating personnel not to exacerbate their suffering and not to administer futile treatment. When is cardiopulmonary resuscitation futile in these patients? Systematic literature searches were conducted in PubMed for the period 1989-2010 on the results of in-hospital cardiopulmonary resuscitation in advanced cancer patients and on factors that affected the results of CPR when special mention was made of cancer. The searches yielded 333 hits and 18 included articles: four meta-analyses, eight retrospective clinical studies, and six review articles. Cancer patients had a poorer post-CPR survival than non-cancer patients. Survival declined with increasing extent of the cancer disease. Widespread and therapy-resistant cancer disease coupled with a performance status lower than WHO 2 or a PAM score (Pre-Arrest Morbidity Index) of above 8 was regarded as inconsistent with survival after cardiopulmonary resuscitation. Cardiopulmonary resuscitation is futile for in-hospital cancer patients with widespread incurable disease and poor performance status.

    To demonstrate the resuscitation-promoting activities of recombinant YeaZ from Vibrio harveyi SF-1. The gene of resuscitation-promoting factor YeaZ was cloned from genomic DNA of V. harveyi SF-1. The gene was expressed in Escherichia coli, and the expressed protein was purified by Ni 2+ -affinity chromatography. A yeaZ mutant was constructed by using the suicide plasmid pNQ705 with homologous recombination. Disruption of yeaZ did not affect cell growth significantly in 2216 E broth at 28°C. The wild-type and mutant viable but nonculturable (VBNC) cells could be resuscitated by temperature upshift method. In addition, the recombinant YeaZ increased the culturable counts from 1·27 × 10 4  CFU per ml and 1·99 × 10 4 CFU per ml to 2·88 × 10 5  CFU per ml and 4·59 × 10 5 CFU per ml, respectively. After the VBNC cells of wild-type and mutant cells were maintained at 4°C for 120 days, no resuscitation was obtained by temperature upshift method, but addition of the recombinant YeaZ promoted the resuscitation of the wild-type and mutant cells, with the culturable cell counts of 1·13 × 10 3 and 1·44 × 10 3 CFU per ml, respectively. Disruption of yeaZ decreased the virulence of V. harveyi in zebrafish. The lethal dose 50% of the yeaZ null mutant was more than 10-fold higher than that of the wild-type cells. The recombinant YeaZ could efficiently promote resuscitation of the wild-type and mutant cells of V. harveyi from VBNC to culturable state. The protein also promoted resuscitation of the VBNC wild-type and mutant cells, which were maintained at 4°C for 120 days and not recovered by temperature upshift method. Disruption of yeaZ decreased the virulence of V. harveyi in zebrafish. Here, we show clear evidence of a resuscitation-promoting factor YeaZ of V. harveyi and the roles in resuscitation of the VBNC cells and its pathogenicity. © 2016 The Society for Applied Microbiology.

    Recent evidence suggested that the quality of cardio-pulmonary resuscitation (CPR) during adult advanced life support training was suboptimal. This study aimed to assess the CPR quality of a paediatric resuscitation training programme, and to determine whether it was sufficiently addressed by the trainee team leaders during training. CPR quality of 20 consecutive resuscitation scenario training sessions was audited prospectively using a pre-designed proforma. A consultant intensivist and a senior nurse who were also Advanced Paediatric Life Support (APLS) instructors assessed the CPR quality which included ventilation frequency, chest compression rate and depth, and any unnecessary interruption in chest compressions. Team leaders' response to CPR quality and elective change of compression rescuer during training were also recorded. Airway patency was not assessed in 13 sessions while ventilation rate was too fast in 18 sessions. Target compression rate was not achieved in only 1 session. The median chest compression rate was 115 beats/min. Chest compressions were too shallow in 10 sessions and were interrupted unnecessarily in 13 sessions. More than 50% of training sessions did not have elective change of the compression rescuer. 19 team leaders failed to address CPR quality during training despite all team leaders being certified APLS providers. The quality of CPR performance was suboptimal during paediatric resuscitation training and team leaders-in-training had little awareness of this inadequacy. Detailed CPR quality assessment and feedback should be integrated into paediatric resuscitation training to ensure optimal performance in real life resuscitations.

    Conclusion: Although the initial resuscitation success rate was not affected by age, a longer time interval between the last medical staffs’ visit and the onset of resuscitation did result in a worse success rate in elderly patients. Our data suggest that more frequent staff visits to the elderly population during hospitalization could alter initial resuscitation results.

    Changes in cerebral glucose metabolism may be an early prognostic indicator of perinatal hypoxic-ischaemic injury. In this study dynamic 18 F-FDG PET was used to evaluate cerebral glucose metabolism in piglets after global perinatal hypoxia and the impact of the resuscitation strategy using room air or hyperoxia. New-born piglets (n = 16) underwent 60 min of global hypoxia followed by 30 min of resuscitation with a fraction of inspired oxygen (FiO 2 ) of 0.21 or 1.0. Dynamic FDG PET, using a microPET system, was performed at baseline and repeated at the end of resuscitation under stabilized haemodynamic conditions. MRI at 3 T was performed for anatomic correlation. Global and regional cerebral metabolic rates of glucose (CMR gl ) were assessed by Patlak analysis for the two time-points and resuscitation groups. Global hypoxia was found to cause an immediate decrease in cerebral glucose metabolism from a baseline level (mean ± SD) of 21.2 ± 7.9 to 12.6 ± 4.7 μmol/min/100 g (p gl but no significant differences in global or regional CMR gl between the resuscitation groups were found. Dynamic FDG PET detected decreased cerebral glucose metabolism early after perinatal hypoxia in piglets. The decrease in CMR gl may indicate early changes of mild cerebral hypoxia-ischaemia. No significant effect of hyperoxic resuscitation on the degree of hypometabolism was found in this early phase after hypoxia. Cerebral FDG PET can provide new insights into mechanisms of perinatal hypoxic-ischaemic injury where early detection plays an important role in instituting therapy. (orig.)

    For dogs and cats that experience cardiopulmonary arrest, rates of survival to discharge are 6% to 7%, as compared with survival rates of 20% for people. The introduction of standardized cardiopulmonary resuscitation guidelines and training in human medicine has led to substantial improvements in outcome. The Reassessment Campaign on Veterinary Resuscitation initiative recently completed an exhaustive literature review and generated a set of evidence-based, consensus cardiopulmonary resuscitation guidelines in 5 domains: preparedness and prevention, basic life support, advanced life support, monitoring, and postcardiac arrest care. This article reviews some of the most important of these new guidelines. Copyright © 2013 Elsevier Inc. All rights reserved.

  19. Attenuation of pancreatitis-induced pulmonary injury by aerosolized hypertonic saline.

    Shields, C J

    2012-02-03

    BACKGROUND: The immunomodulatory effects of hypertonic saline (HTS) provide potential strategies to attenuate inappropriate inflammatory reactions. This study tested the hypothesis that administration of intratracheal aerosolized HTS modulates the development of lung injury in pancreatitis. METHODS: Pancreatitis was induced in 24 male Sprague-Dawley rats by intraperitoneal injection of 20% L-arginine (500 mg\\/100 g body weight). At 24 and 48 h, intratracheal aerosolized HTS (7.5% NaCl, 0.5 mL) was administered to 8 rats, while a further 8 received 0.5 mL of aerosolized normal saline (NS). At 72 hours, pulmonary neutrophil infiltration (myeloperoxidase activity) and endothelial permeability (bronchoalveolar lavage and wet:dry weight ratios) were assessed. In addition, histological assessment of representative lung tissue was performed by a blinded assessor. In a separate experiment, polymorphonucleocytes (PMN) were isolated from human donors, and exposed to increments of HTS. Neutrophil transmigration across an endothelial cell layer, VEGF release, and apoptosis at 1, 6, 12, 18, and 24 h were assessed. RESULTS: Histopathological lung injury scores were significantly reduced in the HTS group (4.78 +\\/- 1.43 vs. 8.64 +\\/- 0.86); p < 0.001). Pulmonary neutrophil sequestration (1.40 +\\/- 0.2) and increased endothelial permeability (6.77 +\\/- 1.14) were evident in the animals resuscitated with normal saline when compared with HTS (0.70 +\\/- 0.1 and 3.57 +\\/- 1.32), respectively; p < 0.04). HTS significantly reduced PMN transmigration (by 97.1, p = 0.002, and induced PMN apoptosis (p < 0.03). HTS did not impact significantly upon neutrophil VEGF release (p > 0.05). CONCLUSIONS: Intratracheal aerosolized HTS attenuates the neutrophil-mediated pulmonary insult subsequent to pancreatitis. This may represent a novel therapeutic strategy.

    In order to enhance patient safety during resuscitation of critically ill patients, we need to optimize team communication and enhance team situational awareness but little is known about resuscitation team communication patterns. The objective of this study is to understand how teams communicate during resuscitation; specifically to assess for a shared mental model (organized understanding of a team's relationships) and information needs. We triangulated 3 methods to evaluate resuscitation team communication at a tertiary care academic trauma center: (1) interviews; (2) simulated resuscitation observations; (3) live resuscitation observations. We interviewed 18 resuscitation team members about shared mental models, roles and goals of team members and procedural expectations. We observed 30 simulated resuscitation video recordings and documented the timing, source and destination of communication and the information category. We observed 12 live resuscitations in the emergency department and recorded baseline characteristics of the type of resuscitations, nature of teams present and type and content of information exchanges. The data were analyzed using a qualitative communication analysis method. We found that resuscitation team members described a shared mental model. Respondents understood the roles and goals of each team member in order to provide rapid, efficient and life-saving care with an overall need for situational awareness. The information flow described in the interviews was reflected during the simulated and live resuscitations with the most responsible physician and charting nurse being central to team communication. We consolidated communicated information into six categories: (1) time; (2) patient status; (3) patient history; (4) interventions; (5) assistance and consultations; 6) team members present. Resuscitation team members expressed a shared mental model and prioritized situational awareness. Our findings support a need for cognitive aids to

    The quality of chest compression is a determinant of survival after cardiac arrest. Therefore, the European Resuscitation Council (ERC) 2010 guidelines on resuscitation strongly focus on compression quality. Despite its impact on survival, observational studies have shown that chest compression quality is not reached by professional rescue teams. Real-time feedback devices for resuscitation are able to measure chest compression during an ongoing resuscitation attempt through a sternal sensor equipped with a motion and pressure detection system. In addition to the electrocardiograph (ECG) ventilation can be detected by transthoracic impedance monitoring. In cases of quality deviation, such as shallow chest compression depth or hyperventilation, feedback systems produce visual or acoustic alarms. Rescuers can thereby be supported and guided to the requested quality in chest compression and ventilation. Feedback technology is currently available both as a so-called stand-alone device and as an integrated feature in a monitor/defibrillator unit. Multiple studies have demonstrated sustainable enhancement in the education of resuscitation due to the use of real-time feedback technology. There is evidence that real-time feedback for resuscitation combined with training and debriefing strategies can improve both resuscitation quality and patient survival. Chest compression quality is an independent predictor for survival in resuscitation and should therefore be measured and documented in further clinical multicenter trials.

    2000-09-01

    Full Text Available Doctors and nurses working in hospital emergency departments face ethical and moral conflicts more so than in other health care units. Traditional curricular approaches to health professional education have been embedded in a discriminatory societal context and as such have not prepared health professionals adequately for the ethical realities of their practice. Furthermore, the discourse on ethical theories and ethical principles do not provide clear-cut solutions to ethical dilemmas but rather serve as a guide to ethical decision- making. Within the arena of trauma and resuscitation, fundamental ethical principles such as respect for autonomy, beneficence, non-maleficence and justice cannot be taken as absolutes as these may in themselves create moral conflict. Resuscitation room activities require a balance between what is “ ethically" correct and what is “pragmatically required” . Because of the urgent nature of a resuscitation event, this balance is often under threat, with resultant transgression of patients’ rights. This article explores the sources of ethical and moral issues in trauma care and proposes a culture of human rights to provide a context for preserving and protecting trauma patients’ rights during resuscitation. Recommendations for education and research are alluded to in concluding the article.

    Full Text Available Currently, a limited range of biochemical tests for hypoxia are in clinical use. Early diagnostic and functional biomarkers that mirror cellular metabolism and recovery during resuscitation are lacking. We hypothesized that the quantification of metabolites after hypoxia and resuscitation would enable the detection of markers of hypoxia as well as markers enabling the monitoring and evaluation of resuscitation strategies.Hypoxemia of different durations was induced in newborn piglets before randomization for resuscitation with 21% or 100% oxygen for 15 min or prolonged hyperoxia. Metabolites were measured in plasma taken before and after hypoxia as well as after resuscitation. Lactate, pH and base deficit did not correlate with the duration of hypoxia. In contrast to these, we detected the ratios of alanine to branched chained amino acids (Ala/BCAA; R(2.adj = 0.58, q-value<0.001 and of glycine to BCAA (Gly/BCAA; R(2.adj = 0.45, q-value<0.005, which were highly correlated with the duration of hypoxia. Combinations of metabolites and ratios increased the correlation to R(2adjust = 0.92. Reoxygenation with 100% oxygen delayed cellular metabolic recovery. Reoxygenation with different concentrations of oxygen reduced lactate levels to a similar extent. In contrast, metabolites of the Krebs cycle (which is directly linked to mitochondrial function including alpha keto-glutarate, succinate and fumarate were significantly reduced at different rates depending on the resuscitation, showing a delay in recovery in the 100% reoxygenation groups. Additional metabolites showing different responses to reoxygenation include oxysterols and acylcarnitines (n = 8-11, q<0.001.This study provides a novel strategy and set of biomarkers. It provides biochemical in vivo data that resuscitation with 100% oxygen delays cellular recovery. In addition, the oxysterol increase raises concerns about the safety of 100% O(2 resuscitation. Our biomarkers can be used in a broad

    Our goal was to compare the confidence, knowledge, and performance of obstetric residents taught initial neonatal resuscitation steps in a simulation-based versus lecture-based format. Our study was a prospective randomized controlled trial of 33 obstetric residents. Baseline confidence, knowledge, and clinical skills assessments were performed. Subjects were randomized to traditional lecture (n = 14) or simulation-based (n = 19) neonatal resuscitation curriculum with a focus on initial steps. Follow-up assessments were performed at 3 and 6 months. Total confidence, knowledge, and clinical performance scores and change from baseline in these scores were calculated and compared between groups. Both the lecture-based and simulated-based groups demonstrated significant improvement in confidence, knowledge, and performance over time. However, compared with the lecture group, the magnitude of the mean change from baseline in performance scores was significantly greater in the simulation group at 3 months (2.9 versus 10.1; p < 0.001), but not at 6 months (7.0 versus 9.3; p = 0.11). Our study demonstrates the superiority of simulation in teaching obstetric residents initial neonatal resuscitation steps compared with a traditional lecture format. Skills are retained for upwards of 3-6 months. Refresher instruction by 6 months post-instruction may be beneficial.

    Full Text Available In recent years, the concept of comprehensive treatment for military trauma has been comprehensively updated. The application of damage control surgery has significantly improved the clinical outcome of severe abdominal injury. With appropriate surgical intervention, post-trauma fluid resuscitation plays an increasingly important role in the treatment of abdominal injury. The damage control resuscitation strategy addresses the importance of permissive hypotension and haemostatic resuscitation for patients with severe trauma, under the guidance of damage control surgical principle.

    Full Text Available Cardiopulmonary resuscitation (CPR is recognized as a medical procedure performed to maintain vital functions of a person whose cardiac and respiratory functions have stopped. Chest compression is the most essential component of CPR and it is performed on the lower half of the sternum. During CPR, many complications may occur because of chest compressions, especially chest injuries including sternum and rib fractures. Rarely tracheal injury, rupture of the stomach, or liver or spleen injury may also occur as complications.In this study, we present two cases of liver injury caused by resuscitation. With this article, we want to emphasize the importance of making correct chest compressions. Keywords: Resuscitation complications, Emergency service, Liver laceration, Autopsy

    Barrier precautions protect patients and providers from blood-borne pathogens. Although barrier precaution compliance has been shown to be low among adult trauma teams, it has not been evaluated during paediatric resuscitations in which perceived risk of disease transmission may be low. The purpose of this study was to identify factors associated with compliance with barrier precautions during paediatric trauma resuscitations. Video recordings of resuscitations performed on injured children (compliance with an established policy requiring gowns and gloves. Depending on activation level, trauma team members included up to six physicians, four nurses, and a respiratory therapist. Multivariate logistic regression was used to determine the effect of team role, resuscitation factors, and injury mechanism on barrier precaution compliance. Over twelve weeks, 1138 trauma team members participated in 128 resuscitations (4.7% penetrating injuries, 9.4% highest level activations). Compliance with barrier precautions was 81.3%, with higher compliance seen among roles primarily at the bedside compared to positions not primarily at the bedside (90.7% vs. 65.1%, pcompliance, while surgical attendings (20.8%) had the lowest (prole, increased compliance was observed during resuscitations of patients with penetrating injuries (OR=3.97 [95% CI: 1.35-11.70], p=0.01), during resuscitations triaged to the highest activation level (OR=2.61 [95% CI: 1.34-5.10], p=0.005), and among team members present before patient arrival (OR=4.14 [95% CI: 2.29-7.39], pCompliance with barrier precautions varies by trauma team role. Team members have higher compliance when treating children with penetrating and high acuity injuries and when arriving before the patient. Interventions integrating barrier precautions into the workflow of team members are needed to reduce this variability and improve compliance with universal precautions during paediatric trauma resuscitations.

    This study aims to explore the relationship between team-leadership skills and quality of cardiopulmonary resuscitation in an adult cardiac-arrest simulation. Factors affecting team-leadership skills were also assessed. Forty advanced life-support providers leading a cardiac arrest team in a standardized cardiac-arrest simulation were videotaped. Background data were collected, including age (in yrs), sex, whether they had received any leadership training in the past, whether they were part of a professional group, the most recent advanced life-support course (in months) they had undergone, advanced life-support instructor/provider status, and whether they had led in any cardiac arrest situation in the preceding 6 months. Participants were scored using the Cardiac Arrest Simulation test score and Leadership Behavior Description Questionnaire for leadership skills. Process-focused quality of cardiopulmonary resuscitation data were collected directly from manikin and video recordings. Primary outcomes were complex technical skills (measured as Cardiac Arrest Simulation test score, preshock pause, and hands-off ratio). Secondary outcomes were simple technical skills (chest-compression rate, depth, and ventilation rate). Univariate linear regressions were performed to examine how leadership skills affect quality of cardiopulmonary resuscitation and bivariate correlations elicited factors affecting team-leadership skills.Teams led by leaders with the best leadership skills performed higher quality cardiopulmonary resuscitation with better technical performance (R = 0.75, p resuscitation training.

    Cytotoxic properties of racemic (D-,L-isomers) lactated Ringer's solution detected in vitro and in small animal experiments, have not been confirmed in large animal models. Our hypothesis was that in a clinically relevant large animal model of hemorrhage, resuscitation with racemic lactated Ringer's solution would induce cellular apoptosis, which can be attenuated by elimination of d-lactate. Yorkshire swine (n = 49, weight 40-58 kg) were subjected to uncontrolled (iliac arterial and venous injuries) and controlled hemorrhage, totaling 40% of estimated blood volume. They were randomized (n = 7/group) to control groups, which consisted of (1) no hemorrhage (NH), (2) no resuscitation (NR), or resuscitation groups, which consisted of (3) 0.9% saline (NS), (4) racemic lactated Ringer's (DL-LR), (5) L-isomer lactated Ringer's (L-LR), (6) Ketone Ringer's (KR), (7) 6% hetastarch in 0.9% saline (Hespan). KR was identical to LR except for equimolar substitution of lactate with beta-hydroxybutyrate. Resuscitation was performed in three phases, simulating (1) prehospital, (2) operative, (3) postoperative/recovery periods. Arterial blood gasses, circulating cytokines (TNF-alpha, IL-1, -6, -10), and markers of organ injury were serially measured. Metabolic activity of brain, and liver, was measured with microdialysis. Four hours postinjury, organs were harvested for Western blotting, ELISA, TUNEL assay, and immunohistochemistry. All resuscitation strategies restored blood pressure, but clearance of lactic acidosis was impeded following DL-LR resuscitation. Metabolic activity decreased during shock and improved with resuscitation, without any significant inter-group differences. Levels of cytokines in circulation were similar, but tissue levels of TNF in liver and lung increased six- and threefolds (p < 0.05) in NR group. In liver, all resuscitation strategies significantly decreased TNF levels compared with the NR group, but in the lung resuscitation with lactated Ringer (DL

    To explore healthcare professionals' experiences around the time of newborn resuscitation in the delivery room, when the baby's father was present. A qualitative descriptive, retrospective design using the critical incident approach. Tape-recorded semistructured interviews were undertaken with healthcare professionals involved in newborn resuscitation. Participants recalled resuscitation events when the baby's father was present. They described what happened and how those present, including the father, responded. They also reflected upon the impact of the resuscitation and the father's presence on themselves. Participant responses were analysed using thematic analysis. A large teaching hospital in the UK. Purposive sampling was utilised. It was anticipated that 35-40 participants would be recruited. Forty-nine potential participants were invited to take part. The final sample consisted of 37 participants including midwives, obstetricians, anaesthetists, neonatal nurse practitioners, neonatal nurses and paediatricians. Four themes were identified: 'whose role?' 'saying and doing' 'teamwork' and 'impact on me'. While no-one was delegated to support the father during the resuscitation, midwives and anaesthetists most commonly took on this role. Participants felt the midwife was the most appropriate person to support fathers. All healthcare professional groups said they often did not know what to say to fathers during prolonged resuscitation. Teamwork was felt to be of benefit to all concerned, including the father. Some paediatricians described their discomfort when fathers came to the resuscitaire. None of the participants had received education and training specifically on supporting fathers during newborn resuscitation. This is the first known study to specifically explore the experiences of healthcare professionals of the father's presence during newborn resuscitation. The findings suggest the need for more focused training about supporting fathers. There is also

    Birth asphyxia represents a serious problem worldwide, resulting in approximately 1 million deaths and an equal number of serious sequelae annually. It is therefore important to develop new and better ways to treat asphyxia. Resuscitation after birth asphyxia traditionally has been carried out with 100% oxygen, and most guidelines and textbooks recommend this; however, the scientific background for this has never been established. On the contrary, theoretic considerations indicate that resuscitation with high oxygen concentrations could have detrimental effects. We have performed a series of animal studies as well as one pilot study indicating that resuscitation can be performed with room air just as efficiently as with 100% oxygen. To test this more thoroughly, we organized a multicenter study and hypothesized that room air is superior to 100% oxygen when asphyxiated newborn infants are resuscitated. In a prospective, international, controlled multicenter study including 11 centers from six countries, asphyxiated newborn infants with birth weight >999 g were allocated to resuscitation with either room air or 100% oxygen. The study was not blinded, and the patients were allocated to one of the two treatment groups according to date of birth. Those born on even dates were resuscitated with room air and those born on odd dates with 100% oxygen. Informed consent was not obtained until after the initial resuscitation, an arrangement in agreement with the new proposal of the US Food and Drug Administration's rules governing investigational drugs and medical devices to permit clinical research on emergency care without the consent of subjects. The protocol was approved by the ethical committees at each participating center. Entry criterion was apnea or gasping with heart rate Apgar score at 5 minutes, heart rate at 90 seconds, time to first breath, time to first cry, duration of resuscitation, arterial blood gases and acid base status at 10 and 30 minutes of age, and

    Full Text Available BACKGROUND: Perinatal hypoxia-ischemia is a major cause of mortality and cerebral morbidity, and using oxygen during newborn resuscitation may further harm the brain. The aim was to examine how supplementary oxygen used for newborn resuscitation would influence early brain tissue injury, cell death and repair processes and the regulation of genes related to apoptosis, neurodegeneration and neuroprotection. METHODS AND FINDINGS: Anesthetized newborn piglets were subjected to global hypoxia and then randomly assigned to resuscitation with 21%, 40% or 100% O(2 for 30 min and followed for 9 h. An additional group received 100% O(2 for 30 min without preceding hypoxia. The left hemisphere was used for histopathology and immunohistochemistry and the right hemisphere was used for in situ zymography in the corpus striatum; gene expression and the activity of various relevant biofactors were measured in the frontal cortex. There was an increase in the net matrix metalloproteinase gelatinolytic activity in the corpus striatum from piglets resuscitated with 100% oxygen vs. 21%. Hematoxylin-eosin (HE staining revealed no significant changes. Nine hours after oxygen-assisted resuscitation, caspase-3 expression and activity was increased by 30-40% in the 100% O(2 group (n = 9/10 vs. the 21% O(2 group (n = 10; p<0.04, whereas brain-derived neurotrophic factor (BDNF activity was decreased by 65% p<0.03. CONCLUSIONS: The use of 100% oxygen for resuscitation resulted in increased potentially harmful proteolytic activities and attenuated BDNF activity when compared with 21%. Although there were no significant changes in short term cell loss, hyperoxia seems to cause an early imbalance between neuroprotective and neurotoxic mechanisms that might compromise the final pathological outcome.

    To determine the effect of continuous limited fluid resuscitation on the hemodynamic response and survival in rats in a model of uncontrolled hemorrhage shock due to Massive Splenic Injury (MSI) and Head Injury (HI). Seventy Sprague-Dawley rats were used in this study. Group 1 rats (n=10) was sham-operated. In group 2 (n=10), only Massive Splenic Injury (MSI) was performed and untreated. In group 3 (n=10), only head injury (HI) was performed and untreated. In group 4 (n=10), HI and MSI were performed and were untreated. In group 5 (n=10), HI and MSI were performed and 15 minutes later treated with 7.5% NaCl. In group 6 (n=10), HI and MSI were performed, and rats were treated with Ringer's Lactate (RL) solution. In group 7 (n=10), HI and MSI were performed, rats were treated with 0.9 % NaCl. In groups 2,4,5,6 and 7 midline incision was reopened and splenectomy was performed at 45 minutes. In group 4 rats, Mean Arterial Pressure (MAP) was decreased from 104 +- 6.1 mmHg to 75 +- 19.5 mmHg at 15 minutes; heart rate decreased from 357+- 24.9 beats/min to 321 +- 62.1 beats/min and hematocrit decreased from 46 +- 1.3 % to 43 +- 2.5 % (p<0.01). Similar early changes in MAP, heart rate and hematocrit were observed in groups 5, 6, and 7, at 15 minutes. At 45,60 and 120 minutes, in fluid resuscitated rats (group 5,6,7) MAP, heart rate and hematocrit values were measured higher than group 2 and 4 (p<0.01 for all). At 120 min. in group 6, hematocrit was higher than group 4, 5 and 7, in group 6, total blood loss after splenectomy was calculated at 20 +- 2.4% of blood volume and was the best value compared to other fluid resuscitated group 5 and 7 (28% and 27% of blood volume) (p<0.01). Mortality was lower in all fluid resuscitated groups when compared to group 3 and 4 (p< 0.05). The median survival time was again higher in fluid resuscitated groups. Continuous infusion of 7.5% NaCl, RL and 0.9 % NaCl following uncontrolled hemorrhagic shock with massive splenic injury and

    After resuscitation, asphyxiated neonates often develop poor cardiac function with hypotension, pulmonary hypertension and multiorgan ischemia. In a swine model of neonatal hypoxia-reoxygenation, effects of epinephrine, dobutamine and milrinone on systemic, pulmonary and regional hemodynamics and oxygen transport were compared. Controlled, block-randomized study. University research laboratory. Mixed breed piglets (1-3 days, 1.5-2.3 kg). In acutely instrumented piglets, normocapnic alveolar hypoxia (10-15% oxygen) was induced for 2 h followed by reoxygenation with 100% oxygen (1 h) then 21% oxygen (3 h). At 2 h of reoxygenation, after volume loading (Ringer's lactate 10 ml/kg), either saline (placebo), epinephrine (0.5 microg/kg/min), dobutamine (20 microg/kg/min) or milrinone (0.75 microg/kg/min) were infused for 2 h in a blinded, block-randomized fashion (n = 6/group). All medications similarly improved cardiac output, stroke volume and systemic oxygen delivery (vs. placebo-controls, p milrinone maintained, mean arterial pressure over pretreatment values while placebo-treated piglets developed hypotension and shock. The mean arterial to pulmonary arterial pressures ratio was not different among groups. All medications significantly increased carotid and intestinal, but not renal, arterial blood flows and oxygen delivery, whereas milrinone caused lower renal vascular resistance than epinephrine and dobutamine-treated groups. Plasma troponin I, plasma and myocardial lactate levels, and histologic ischemic features were not different among groups. In newborn piglets with hypoxia-reoxygenation, epinephrine, dobutamine and milrinone are effective inotropes to improve cardiac output, carotid and intestinal perfusion, without aggravating pulmonary hypertension. Milrinone may also improve renal perfusion.

    Full Text Available Prolonged standard cardiopulmonary resuscitation (CPR does not reliably sustain brain viability during cardiac arrest. Pre-hospital adjuncts to standard CPR are needed in order to improve outcomes. A preliminary dog study demonstrated that surface cooling of the head during arrest and CPR can achieve protective levels of brain hypothermia (30°C within 10 minutes. We hypothesized that protective head-cooling during cardiac arrest and CPR improves neurological outcomes. Twelve dogs under light ketamine-halothane-nitrous oxide anesthesia were arrested by transthoracic fibrillation. The treated group consisted of six dogs whose shaven heads were moistened with saline and packed in ice immediately after confirmation of ventricular fibrillation. Six control dogs remained at room temperature. All 12 dogs were subjected to four minutes of ventricular fibrillation and 20 minutes of standard CPR. Spontaneous circulation was restored with drugs and countershocks. Intensive care was provided for five hours post-arrest and the animals were observed for 24 hours. In both groups, five of the six dogs had spontaneous circulation restored. After three hours, mean neurological deficit was significantly lower in the treated group (P=0.016, with head-cooled dogs averaging 37% and the normothermic dogs 62%. Two of the six head-cooled dogs survived 24 hours with neurological deficits of 9% and 0%, respectively. None of the control group dogs survived 24 hours. We concluded that head-cooling attenuates brain injury during cardiac arrest with prolonged CPR. We review the literature related to the use of hypothermia following cardiac arrest and discuss some promising approaches for the pre-hospital setting.

    Fluid creep is the term applied to a burn resuscitation, which requires more fluid than predicted by standard formulas. Fluid creep is common today and is linked to several serious edema-related complications. Increased fluid requirements may accompany the appropriate resuscitation of massive injuries but dangerous fluid creep is also caused by overly permissive fluid infusion and the lack of colloid supplementation. Several strategies for recognizing and treating fluid creep are presented. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available The purpose of the study was to analyze the Russian legislation to identify the medicolegal aspects of cardiopulmonary resuscitation, which are most significant for an intensive care anesthesiologist. Statutory acts concerning human health care, including those pertinent to cardiopulmonary resuscitation and those providing for the responsibility of medical workers in some cases were analyzed. A number of discrepancies in various legal acts concerning human death verification and resuscitative measures were identified. The analysis has revealed the aspects of cardiopulmonary resuscitation, which are, from the point of view of legislation, most important for the physician.

    It is not known whether simultaneous delivery of hydrogen and oxygen can reduce injury caused by hemorrhagic shock and resuscitation (HSR). This study investigated the therapeutic potential of hyperoxygenated hydrogen-rich solution (HHOS), a combined hydrogen/oxygen carrier, in a rat model of HSR-induced liver injury. Rats (n = 60) were randomly divided into 5 groups (n = 6 per group at each time point). One group underwent sham operation, and the others were subjected to severe hemorrhagic shock and then treated with lactated Ringer's solution (LRS), hydrogen-rich solution, hyperoxygenated solution, or HHOS. At 2 and 6 h after resuscitation, blood samples (n = 6) were collected from the femoral artery and serum concentrations of alanine aminotransferase and aspartate aminotransferase (AST) were measured. Rats were then sacrificed, and histopathological changes in the liver were evaluated by quantifying the percentage of apoptotic cells by caspase-3 immunohistochemistry and terminal deoxynucleotidyl transferase dUTP nick-end labeling. Inflammation was assessed by assessing malondialdehyde content and tumor necrosis factor-α, and interleukin (IL)-6 expression. Compared to lactated Ringer's solution, hydrogen-rich solution, or hyperoxygenated solution groups, serum AST and alanine aminotransferase levels and IL-6, tumor necrosis factor-α, and malondialdehyde expression in liver tissue were decreased by HHOS treatment. The number of caspase-3- and terminal deoxynucleotidyl transferase dUTP nick end labeling-positive cells was decreased (P < 0.05) by HHOS treatment, 2 and 6 h after resuscitation. HHOS has protective effects against liver injury in a rat model of HSR. Copyright © 2017 Elsevier Inc. All rights reserved.

    2012-02-01

    BACKGROUND: Advances in neonatal care continue to lower the limit of viability. Decision making in this grey zone remains a challenging process. OBJECTIVE: To explore the opinions of healthcare providers on resuscitation and outcome in the less than 28-week preterm newborn. DESIGN\\/METHODS: An anonymous postal questionnaire was sent to health care providers working in maternity units in the Republic of Ireland. Questions related to neonatal management of the extreme preterm infant, and estimated survival and long-term outcome. RESULTS: The response rate was 55% (74% obstetricians and 70% neonatologists). Less than 1% would advocate resuscitation at 22 weeks, 10% of health care providers advocate resuscitation at 23 weeks gestation, 80% of all health care providers would resuscitate at 24 weeks gestation. 20% of all health care providers would advocate cessation of resuscitation efforts on 22-25 weeks gestation at 5 min of age. 65% of Neonatologists and 54% trainees in Paediatrics would cease resuscitation at 10 min of age. Obstetricians were more pessimistic about survival and long term outcome in newborns delivered between 23 and 27 weeks when compared with neonatologists. This difference was also observed in trainees in paediatrics and obstetrics. CONCLUSION: Neonatologists, trainees in paediatrics and neonatal nurses are generally more optimistic about outcome than their counterparts in obstetrical care and this is reflected in a greater willingness to provide resuscitation efforts at the limits of viability.

    To summarize current available data on simulation-based training in resuscitation for health care professionals. MEDLINE, EMBASE, CINAHL, PsycINFO, ERIC, Web of Science, Scopus and reference lists of published reviews. Published studies of any language or date that enrolled health professions' learners to investigate the use of technology-enhanced simulation to teach resuscitation in comparison with no intervention or alternative training. Data were abstracted in duplicate. We identified themes examining different approaches to curriculum design. We pooled results using random effects meta-analysis. 182 studies were identified involving 16,636 participants. Overall, simulation-based training of resuscitation skills, in comparison to no intervention, appears effective regardless of assessed outcome, level of learner, study design, or specific task trained. In comparison to no intervention, simulation training improved outcomes of knowledge (Hedges' g) 1.05 (95% confidence interval, 0.81-1.29), process skill 1.13 (0.99-1.27), product skill 1.92 (1.26-2.60), time skill 1.77 (1.13-2.42) and patient outcomes 0.26 (0.047-0.48). In comparison with non-simulation intervention, learner satisfaction 0.79 (0.27-1.31) and process skill 0.35 (0.12-0.59) outcomes favored simulation. Studies investigating how to optimize simulation training found higher process skill outcomes in courses employing "booster" practice 0.13 (0.03-0.22), team/group dynamics 0.51 (0.06-0.97), distraction 1.76 (1.02-2.50) and integrated feedback 0.49 (0.17-0.80) compared to courses without these features. Most analyses reflected high between-study inconsistency (I(2) values >50%). Simulation-based training for resuscitation is highly effective. Design features of "booster" practice, team/group dynamics, distraction and integrated feedback improve effectiveness. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    Cardiac arrest is a major public health problem affecting thousands of individuals each year in both the before hospital and in-hospital settings. However, although the scope of the problem is large, the quality of care provided during resuscitation attempts frequently does not meet quality of care standards, despite evidence-based cardiopulmonary resuscitation (CPR) guidelines, extensive provider training, and provider credentialing in resuscitation medicine. Although this fact may be disappointing, it should not be surprising. Resuscitation of the cardiac arrest victim is a highly complex task requiring coordination between various levels and disciplines of care providers during a stressful and relatively infrequent clinical situation. Moreover, it requires a targeted, high-quality response to improve clinical outcomes of patients. Therefore, solutions to improve care provided during resuscitation attempts must be multifaceted and targeted to the diverse number of care providers to be successful. PMID:22107978

    Resuscitation of infants at 23 weeks' gestation remains controversial; clinical practices vary. We sought to investigate the cost effectiveness of resuscitation of infants born 23 0/7-23 6/7 weeks' gestation. Decision-analytic modeling comparing universal and selective resuscitation to non-resuscitation for 5176 live births at 23 weeks in a theoretic U.S. cohort. Estimates of death (77%) and disability (64-86%) were taken from the literature. Maternal and combined maternal-neonatal utilities were applied to discounted life expectancy to generate QALYs. Incremental cost-effectiveness ratios were calculated, discounting costs and QALYs. Main outcomes included number of survivors, their outcome status and incremental cost-effectiveness ratios for the three strategies. A cost-effectiveness threshold of $100 000/QALY was utilized. Universal resuscitation would save 1059 infants: 138 severely disabled, 413 moderately impaired and 508 without significant sequelae. Selective resuscitation would save 717 infants: 93 severely disabled, 279 moderately impaired and 343 without significant sequelae. For mothers, non-resuscitation is less expensive ($19.9 million) and more effective (127 844 mQALYs) than universal resuscitation ($1.2 billion; 126 574 mQALYs) or selective resuscitation ($845 million; 125 966 mQALYs). For neonates, both universal and selective resuscitation were cost-effective, resulting in 22 256 and 15 134 nQALYS, respectively, versus 247 nQALYs for non-resuscitation. In sensitivity analyses, universal resuscitation was cost-effective from a maternal perspective only at utilities for neonatal death permissive response to parental requests for aggressive intervention at 23 weeks' gestation.

    Cardiopulmonary resuscitation (CPR) guidelines assume that cardiac arrest victims can be treated with a uniform chest compression (CC) depth and a standardized interval administration of vasopressor drugs. This non-personalized approach does not incorporate a patient’s individualized response into ongoing resuscitative efforts. In previously reported porcine models of hypoxic and normoxic ventricular fibrillation (VF), a hemodynamic-directed resuscitation improved short-term survival compared...

    Cardiac arrest occurs at a higher rate in children with heart disease than in healthy children. Pediatric basic life support and advanced life support guidelines focus on delivering high-quality resuscitation in children with normal hearts. The complexity and variability in pediatric heart disease pose unique challenges during resuscitation. A writing group appointed by the American Heart Association reviewed the literature addressing resuscitation in children with heart disease. MEDLINE and Google Scholar databases were searched from 1966 to 2015, cross-referencing pediatric heart disease with pertinent resuscitation search terms. The American College of Cardiology/American Heart Association classification of recommendations and levels of evidence for practice guidelines were used. The recommendations in this statement concur with the critical components of the 2015 American Heart Association pediatric basic life support and pediatric advanced life support guidelines and are meant to serve as a resuscitation supplement. This statement is meant for caregivers of children with heart disease in the prehospital and in-hospital settings. Understanding the anatomy and physiology of the high-risk pediatric cardiac population will promote early recognition and treatment of decompensation to prevent cardiac arrest, increase survival from cardiac arrest by providing high-quality resuscitations, and improve outcomes with postresuscitation care. © 2018 American Heart Association, Inc.

    Full Text Available The most severe effects in amitriptiline intoxications are related with central nervous system and cardiovascular system. Amitriptiline intoxication especially with high doses has severe cardiac effects and can result in cardiac arrest. Most favorable responses can be achieved with efficient and prolonged cardiopulmonary resuscitation. We wanted to present a case ingested high dose of amitriptiline for attempt to suicide and responded to prolonged cardiopulmonary resuscitation.

    Full Text Available Birth Asphyxia is considered to be one of the leading causes of neonatal mortality around the world. Asphyxiated neonates require skilled resuscitation to survive the neonatal period. The project aims to train health professionals in a basic newborn care using a prototype with an ultimate objective to have one person at every delivery trained in neonatal resuscitation. This prototype will be a user-friendly device with which one can get trained in performing neonatal resuscitation in resource-limited settings. The prototype consists of a Force Sensing Resistor (FSR that measures the pressure applied and is interfaced with Arduino® which controls the Liquid Crystal Display (LCD and Light Emitting Diode (LED indication for pressure and compression counts. With the increase in population and absence of proper medical care, the need for neonatal resuscitation program is not well addressed. The proposed work aims at offering a promising solution for training health care individuals on resuscitating newborn babies under low resource settings.

    Intra-venous (IV) burn resuscitation is effective; nevertheless it has its disadvantages. WHO Oral Rehydration Solution (ORS) has shown high effectiveness in treating dehydration. WHO-ORS, with salt supplement, seems to be suitable for burn resuscitation, where IV resuscitation is not available, feasible or possible. The objective of the study was to evaluate acute phase efficacy and safety, as well as limitations and complications of burn resuscitation using WHO-ORS and salt tablets. This randomized controlled clinical trial was conducted in the Burn Unit, Suez Canal University Hospital, Ismailia, Egypt. The study group was given WHO-ORS (15% of body weight/day) with one salt tablet (5gm) per liter according to Sørensen's formula. The control group was given IV fluids according to the Parkland formula. Patients' vital signs and urine output were monitored for 72 hours after starting resuscitation. Both groups were comparable regarding age, sex, and percentage, etiology and degree of burns. For all assessed parameters, there were no major significant differences between the study group (10 cases) and control group (20 cases). Even where there was a significant difference, apart from blood pressure in the first hour of the first day, the study group never crossed safe limits for pulse, systolic blood pressure, urine output, respiratory rate and conscious level. WHO-ORS with 5gm salt tablets, given according to Sørenson's formula, is a safe and efficient alternative for IV resuscitation. It could even be a substitute, particularly in low resource settings and fire disasters.

    The timely administration of analgesics is crucial to the comprehensive management of trauma patients. When an emergency department (ED) pharmacist participates in trauma resuscitation, the pharmacist acts as a medication resource for trauma team members and facilitates the timely administration of analgesics. This study measured the impact of a pharmacist on time to first analgesic dose administered during trauma resuscitation. All adult (>18 years) patients who presented to this level II trauma center via activation of the trauma response system between January 1, 2009, and May 31, 2013, were screened for eligibility. For inclusion, patients must have received intravenous fentanyl, morphine, or hydromorphone in the trauma bay. The time to medication administration was defined as the elapsed time from ED arrival to administration of first analgesic. There were 1328 trauma response system activations during the study period; of which 340 patients were included. The most common analgesic administered was fentanyl (62% in both groups). When a pharmacist was participating, the mean time to first analgesic administered was decreased (17 vs 21 minutes; P = .03). Among the 78% of patients with documented pain scores, the overall mean reduction in pain scores from ED arrival to ED discharge was similar between the 2 groups. There was a 2.4 point reduction with a pharmacist versus 2.7 without a pharmacist, using a 0 to 10 numeric pain rating scale. The participation of a clinical pharmacist during trauma resuscitation significantly decreased the time to first analgesic administration in trauma patients. The results of this study supplement the literature supporting the integration of clinical ED pharmacists on trauma teams.

    To assess development of fatigue during chest compressions (CCs) in simulated neonatal cardiopulmonary resuscitation (CPR). Prospective randomized manikin crossover study. Thirty neonatal healthcare professionals who successfully completed the Neonatal Resuscitation Program performed CPR using (i) 3:1 compression:ventilation (C:V) ratio, (ii) continuous CC with asynchronous ventilation (CCaV) at a rate of 90 CC per min and (iii) CCaV at 120 CC per min for a duration of 10 min on a neonatal manikin. Changes in peak pressure (a surrogate of fatigue) and CC rate were continuously recorded and fatigue among groups was compared. Participants were blinded to pressure tracings and asked to rate their level of comfort and fatigue for each CPR trial. Compared with baseline, a significant decrease in peak pressure was observed after 72, 96 and 156 s in group CCaV-120, CCaV-90 and 3:1 C:V, respectively. CC depth decreased by 50% within the first 3 min during CCaV-120, 30% during CCaV-90 and 20% during 3:1 C:V. Moreover, 3:1 C:V and CCaV were similarly preferred by healthcare professionals. Similarly, 3:1 C:V and CCaV CPR were also fatiguing. We recommend that rescuers should switch after every second cycle of heart rate assessment during neonatal CPR.

    Utstein-style guidelines use an established consensus process, endorsed by the international resuscitation community, to facilitate and structure resuscitation research and publication. The first "Guidelines for Uniform Reporting of Data From Drowning" were published over a decade ago. During the intervening years, resuscitation science has advanced considerably, thus making revision of the guidelines timely. In particular, measurement of cardiopulmonary resuscitation elements and neurological outcomes reporting have advanced substantially. The purpose of this report is to provide updated guidelines for reporting data from studies of resuscitation from drowning. An international group with scientific expertise in the fields of drowning research, resuscitation research, emergency medical services, public health, and development of guidelines met in Potsdam, Germany, to determine the data that should be reported in scientific articles on the subject of resuscitation from drowning. At the Utstein-style meeting, participants discussed data elements in detail, defined the data, determined data priority, and decided how data should be reported, including scoring methods and category details. The template for reporting data from drowning research was revised extensively, with new emphasis on measurement of quality of resuscitation, neurological outcomes, and deletion of data that have proved to be less relevant or difficult to capture. The report describes the consensus process, rationale for selecting data elements to be reported, definitions and priority of data, and scoring methods. These guidelines are intended to improve the clarity of scientific communication and the comparability of scientific investigations.

The purpose of this study is to evaluate an innovative simulation-based IP educational module for undergraduate nursing and medical students on cardiac resuscitation skills.Methods: Nursing and medical trainees participated in a new cardiac resuscitation curriculum involving a 2-hour IP foundational cardiac resuscitation skills lab, followed by three 2-hour IP simulation sessions. Control group participants attended the existing two 2-hour IP simulation sessions. Study respondents (N = 71 completed a survey regarding their confidence performing cardiac resuscitation skills and their perceptions of IP collaboration.Results: Despite a consistent positive trend, only one out of 17 quantitative survey items were significantly improved for learners in the new curriculum. They were more likely to report feeling confident managing the airway during cardiac resuscitation (P = 0.001. Overall, quantitative results suggest that senior nursing and medical students were comfortable with IP communication and teamwork and confident with cardiac resuscitation skills. There were no significant differences between nursing students’ and medical students’ results. Through qualitative feedback, participants reported feeling comfortable learning with students from other professions and found value in the IP simulation sessions.Conclusion: Results from this study will inform ongoing restructuring of the IP cardiac resuscitation skills simulation module as defined by the action research process. Specific improvements that are suggested by these findings include strengthening the team

    This prospective longitudinal study over 6 years compared schoolteachers and emergency physicians as resuscitation trainers for schoolchildren. It also investigated whether pupils who were trained annually for 3 years retain their resuscitation skills after the end of this study. A total of 261 pupils (fifth grade) at two German grammar schools received resuscitation training by trained teachers or by emergency physicians. The annual training events stopped after 3 years in one group and continued for 6 years in a second group. We measured knowledge about resuscitation (questionnaire), chest compression rate (min(-1)), chest compression depth (mm), ventilation rate (min(-1)), ventilation volume (mL), self-efficacy (questionnaire). Their performance was evaluated after 1, 3 and 6 years. The training events increased the pupils' knowledge and practical skills. When trained by teachers, the pupils achieved better results for knowledge (92.86% ± 8.38 vs. 90.10% ± 8.63, P=0.04) and ventilation rate (4.84/min ± 4.05 vs. 3.76/min ± 2.37, P=0.04) than when they were trained by emergency physicians. There were no differences with regard to chest compression rate, depth, ventilation volume, or self-efficacy at the end of the study. Knowledge and skills after 6 years were equivalent in the group with 6 years training compared with 3 years training. Trained teachers can provide adequate resuscitation training in schools. Health-care professionals are not mandatory for CPR training (easier for schools to implement resuscitation training). The final evaluation after 6 years showed that resuscitation skills are retained even when training is interrupted for 3 years. Copyright © 2016 The Authors. Published by Elsevier Ireland Ltd..

    To describe the design and to present the results of a paediatric and neonatal cardiopulmonary resuscitation (CPR) training program adapted to Latin-America. A paediatric CPR coordinated training project was set up in several Latin-American countries with the instructional and scientific support of the Spanish Group for Paediatric and Neonatal CPR. The program was divided into four phases: CPR training and preparation of instructors; training for instructors; supervised teaching; and independent teaching. Instructors from each country participated in the development of the next group in the following country. Paediatric Basic Life Support (BLS), Paediatric Intermediate (ILS) and Paediatric Advanced (ALS) courses were organized in each country adapted to local characteristics. Five Paediatric Resuscitation groups were created sequentially in Honduras (2), Guatemala, Dominican Republican and Mexico. During 5 years, 6 instructors courses (94 students), 64 Paediatric BLS Courses (1409 students), 29 Paediatrics ILS courses (626 students) and 89 Paediatric ALS courses (1804 students) were given. At the end of the program all five groups are autonomous and organize their own instructor courses. Training of autonomous Paediatric CPR groups with the collaboration and scientific assessment of an expert group is a good model program to develop Paediatric CPR training in low- and middle income countries. Participation of groups of different countries in the educational activities is an important method to establish a cooperation network.

    Family presence during resuscitation is an emerging trend, yet it remains controversial, even in countries with relatively high acceptance of family presence during resuscitation among medical professionals. Family presence during resuscitation is not common in many countries, and medical professionals in these regions are unfamiliar with family presence during resuscitation. Therefore, this study predicted the medical professionals' intention to allow family presence during resuscitation by applying the theory of planned behaviour. A cross-sectional survey. A single medical centre in southern Taiwan. Medical staffs including physicians and nurses in a single medical centre (n=714). A questionnaire was constructed to measure the theory of planned behaviour constructs of attitudes, subjective norms, perceived behavioural control, and behavioural intentions as well as the awareness of family presence during resuscitation and demographics. In total, 950 questionnaires were distributed to doctors and nurses in a medical centre. Among the 714 valid questionnaires, only 11 participants were aware of any association in Taiwan that promotes family presence during resuscitation; 94.7% replied that they were unsure (30.4%) or that their unit did not have a family presence during resuscitation policy (74.8%). Regression analysis was performed to predict medical professionals' intention to allow family presence during resuscitation. The results indicated that only positive attitudes and subjective norms regarding family presence during resuscitation and clinical tenure could predict the intention to allow family presence during resuscitation. Because Family presence during resuscitation practice is not common in Taiwan and only 26.19% of the participants agreed to both items measuring the intention to allow family presence during resuscitation, we recommend the implementation of a family presence during resuscitation education program that will enhance the positive beliefs

    Neonatal resuscitation requires both technical and behavioral skills. Key behavioral skills in neonatal resuscitation have been identified by the Neonatal Resuscitation Program. Correlations and interactions between technical skills and behavioral skills in neonatal resuscitation were investigated. Behavioral skills were evaluated via blinded video review of 45 simulated neonatal resuscitations using a validated assessment tool. These were statistically correlated with previously obtained technical skill performance data. Technical skills and behavioral skills were strongly correlated (ρ=0.48; P=0.001). The strongest correlations were seen in distribution of workload (ρ=0.60; P=0.01), utilization of information (ρ=0.55; P=0.03) and utilization of resources (ρ=0.61; P=0.01). Teams with superior behavioral skills also demonstrated superior technical skills, and vice versa. Technical and behavioral skills were highly correlated during simulated neonatal resuscitations. Individual behavioral skill correlations are likely dependent on both intrinsic and extrinsic factors.

    Per the American Heart Association guidelines, extracorporeal cardiopulmonary resuscitation should be considered for in-hospital patients with easily reversible cardiac arrest. However, there are currently no consensus recommendations regarding resuscitation for prolonged cardiac arrest cases. We encountered a 48-year-old man who survived a cardiac arrest that lasted approximately 1.5 hours. He visited a local hospital's emergency department complaining of chest pain and dyspnea that had started 3 days earlier. Immediately after arriving in the emergency department, a cardiac arrest occurred; he was transferred to our hospital for extracorporeal membrane oxygenation (ECMO). Resuscitation was performed with strict adherence to the American Heart Association/American College of Cardiology advanced cardiac life support guidelines until ECMO could be placed. On hospital day 7, he had a full neurologic recovery. On hospital day 58, additional treatments, including orthotopic heart transplantation, were considered necessary; he was transferred to another hospital. To our knowledge, this is the first case in South Korea of patient survival with good neurologic outcomes after resuscitation that lasted as long as 1.5 hours. Documenting cases of prolonged resuscitation may lead to updated guidelines and improvement of outcomes of similar cases in future. Copyright © 2017 The Authors.

In this paper, we describe the application of simulation in pediatric resuscitation training and review the evidence for the use of simulation in neonatal resuscitation, pediatric advanced life support, procedural skills training, and crisis resource management training. We also highlight studies supporting several key instructional design elements that enhance learning, including the use of high-fidelity simulation, distributed practice, deliberate practice, feedback, and debriefing. Simulation-based training is an effective modality for teaching pediatric resuscitation concepts. Current literature has revealed some research gaps in simulation-based education, which could indicate the direction for the future of pediatric resuscitation research.

    Cardiopulmonary resuscitation (CPR) remains a cornerstone in the treatment of cardiac arrest, and is directly linked to survival rates. Nurses are often first responders and need to be skilled in the performance of cardiopulmonary resuscitation. As cardiopulmonary resuscitation skills deteriorate rapidly, the purpose of this study was to investigate whether there was an association between participants' cardiopulmonary resuscitation training and their practical cardiopulmonary resuscitation test results. This comparative study was conducted at the 2014 EuroHeartCare meeting in Stavanger ( n=133) and the 2008 Spring Meeting on Cardiovascular Nursing in Malmö ( n=85). Participants performed cardiopulmonary resuscitation for three consecutive minutes CPR training manikins from Laerdal Medical®. Data were collected with a questionnaire on demographics and participants' level of cardiopulmonary resuscitation training. Most participants were female (78%) nurses (91%) from Nordic countries (77%), whose main role was in nursing practice (63%), and 71% had more than 11 years' experience ( n=218). Participants who conducted cardiopulmonary resuscitation training once a year or more ( n=154) performed better regarding ventilation volume than those who trained less (859 ml vs. 1111 ml, p=0.002). Those who had cardiopulmonary resuscitation training offered at their workplace ( n=161) also performed better regarding ventilation volume (889 ml vs. 1081 ml, p=0.003) and compression rate per minute (100 vs. 91, p=0.04) than those who had not. Our study indicates a positive association between participants' performance on the practical cardiopulmonary resuscitation test and the frequency of cardiopulmonary resuscitation training and whether cardiopulmonary resuscitation training was offered in the workplace. Large ventilation volumes were the most common error at both measuring points.

    The purpose of this study was to determine (1) the role of emergency cardiopulmonary bypass (CPB) after prolonged cardiac arrest and failed cardiopulmonary resuscitation, and (2) the use of systemic hyperkalemia during CPB to convert intractable ventricular fibrillation (VF). Thirty-one pigs (34 +/- 2 kg) underwent 15 minutes of cardiac arrest after induced VF, followed by 10 minutes of cardiopulmonary resuscitation-advanced life support. Peripheral CPB was used if cardiopulmonary resuscitation failed to restore stable circulation. Damage was assessed by evaluating hemodynamics, biochemical variables (creatine kinase-MB, neuron-specific enolase), neurologic deficit score, and brain magnetic resonance imaging. Cardiopulmonary resuscitation alone was successful in only 19% (6 of 31 pigs). Cardiopulmonary bypass was initiated in 81% of animals (25 of 31 pigs) either for hypotension (5 of 25 pigs) or intractable VF (20 of 25 pigs). Defibrillation was successful in 7 of 20 animals during the first 10 minutes after initiating CPB. Ventricular fibrillation persisted more than 10 minutes in 13 of 20 pigs, and animals were treated either with repeated defibrillation (6 of 13 pigs) or with a potassium bolus (7 of 13 pigs) to induce transient cardiac arrest. Overall survival at 24 hours was 84% with cardiopulmonary resuscitation (100% of pigs with hypotension; 71% in CPB-VF < 10 minutes). Despite CPB, fatal myocardial failure occurred after VF duration of more than 10 minutes in all pigs treated with electrical defibrillation, whereas hyperkalemia allowed 100% cardioversion and 86% survival. Biochemical variables remained elevated in all groups. Similarly, severe brain injury was present in all animals as confirmed by neurologic deficit score (197 +/- 10) and magnetic resonance imaging. Emergency CPB after prolonged cardiac arrest improves survival and allows systemic hyperkalemia to convert intractable VF, but fails to reduce neurologic damage. 2010 The Society of Thoracic

  7. Salinization and Saline Environments

    One of the most conspicuous phenomena of water-quality degradation, particularly in arid and semi-arid zones, is salinization of water and soil resources. Salinization is a long-term phenomenon, and during the last century many aquifers and river basins have become unsuitable for human consumption owing to high levels of salinity. Future exploitation of thousands of wells in the Middle East and in many other water-scarce regions in the world depends, to a large extent, on the degree and rate of salinization. Moreover, every year a large fraction of agricultural land is salinized and becomes unusable.Salinization is a global environmental phenomenon that affects many different aspects of our life (Williams, 2001a, b): changing the chemical composition of natural water resources (lakes, rivers, and groundwater), degrading the quality of water supply to the domestic and agriculture sectors, contribution to loss of biodiversity, taxonomic replacement by halotolerant species ( Williams, 2001a, b), loss of fertile soil, collapse of agricultural and fishery industries, changing of local climatic conditions, and creating severe health problems (e.g., the Aral Basin). The damage due to salinity in the Colorado River Basin alone, for example, ranges between 500 and 750 million per year and could exceed 1 billion per year if the salinity in the Imperial Dam increases from 700 mg L-1 to 900 mg L-1 (Bureau of Reclamation, 2003, USA). In Australia, accelerating soil salinization has become a massive environmental and economic disaster. Western Australia is "losing an area equal to one football oval an hour" due to spreading salinity ( Murphy, 1999). The annual cost for dryland salinity in Australia is estimated as AU700 million for lost land and AU$130 million for lost production ( Williams et al., 2002). In short, the salinization process has become pervasive.Salinity in water is usually defined by the chloride content (mg L-1) or total dissolved solids content (TDS, mg L-1or g

    Simulation-based curriculum has been demonstrated as crucial to nursing education in the development of students' critical thinking and complex clinical skills during a resuscitation simulation. Few studies have comprehensively examined the effectiveness of a standardised simulation-based emergency and intensive care nursing curriculum on the performance of students in a resuscitation simulation. To evaluate the impact of a standardised simulation-based emergency and intensive care nursing curriculum on nursing students' response time in a resuscitation simulation. Two-group, non-randomised quasi-experimental design. A simulation centre in a Chinese University School of Nursing. Third-year nursing students (N = 39) in the Emergency and Intensive Care course were divided into a control group (CG, n = 20) and an experimental group (EG, n = 19). The experimental group participated in a standardised high-technology, simulation-based emergency and intensive care nursing curriculum. The standardised simulation-based curriculum for third-year nursing students consists of three modules: disaster response, emergency care, and intensive care, which include clinical priorities (e.g. triage), basic resuscitation skills, airway/breathing management, circulation management and team work with eighteen lecture hours, six skill-practice hours and twelve simulation hours. The control group took part in the traditional curriculum. This course included the same three modules with thirty-four lecture hours and two skill-practice hours (trauma). Perceived benefits included decreased median (interquartile ranges, IQR) seconds to start compressions [CG 32 (25-75) vs. EG 20 (18-38); p  0.05] and defibrillation [CG 222 (194-254) vs. EG 221 (214-248); p > 0.05] at the beginning of the course. A simulation-based emergency and intensive care nursing curriculum was created and well received by third-year nursing students and associated with decreased response time in a

    All infants have some degree of hypoxia and respiratory acidosis at birth, but these conditions are more profound in the asphyxiated newborn. The newborn infant is very susceptible to cooling and may require warming. Skin temperature should be maintained between 36-36.5°.2 Resuscitation of the asphyxiated newborn must include both ventilatory and metabolic correction. Newborn infants may have cardiorespiratory problems due to asphyxia, drugs given to the mother, intrathoracic disease, anemia, hypovolemia (due to antepartum hemorrhage), hypotension, etc. There is no substitute for oxygen which is the drug of choice in respiratory depression of the newborn. The use of stimulating drugs like Coramine, picrotoxin, alphalobectine, and Megamide has no place in the resuscitation of the asphyxiated newborn. Imagesp74-ap74-bp74-cp74-d PMID:20469196

    Quantitative electroencephalogram (EEG) analysis has shown promising results in studying brain injury and functional recovery after cardiac arrest (CA). However, whether the quantitative characteristics of EEG, as potential indicators of neurological prognosis, are influenced by CA causes is unknown. The purpose of this study was designed to compare the quantitative characteristics of early post-resuscitation EEG between asphyxial CA (ACA) and ventricular fibrillation CA (VFCA) in rats. Thirty-two Sprague-Dawley rats of both sexes were randomized into either ACA or VFCA group. Cardiopulmonary resuscitation was initiated after 5-min untreated CA. Characteristics of early post-resuscitation EEG were compared, and the relationships between quantitative EEG features and neurological outcomes were investigated. Compared with VFCA, serum level of S100B, neurological deficit score and brain histopathologic damage score were dramatically higher in the ACA group. Quantitative measures of EEG, including onset time of EEG burst, time to normal trace, burst suppression ratio, and information quantity, were significantly lower for CA caused by asphyxia and correlated with the 96-h neurological outcome and survival. Characteristics of earlier post-resuscitation EEG differed between cardiac and respiratory causes. Quantitative measures of EEG not only predicted neurological outcome and survival, but also have the potential to stratify CA with different causes.

    Good-quality cardiopulmonary resuscitation (CPR) is highlighted in the International Resuscitation Guidelines, but clinically the quality of CPR is often poor. Education of CPR has a major role in the primary skills imparted to students. Different methods can be used to teach CPR quality. We evaluated the current status of their usage in Finland institutes teaching students of emergency medicine at different levels. The following institutes were included in an anonymous survey: medical schools (teaching future physicians), universities of applied sciences (paramedics), colleges (emergency medical technicians) and emergency services college (fire-fighters). Hours of teaching theory lessons of CPR and hours of small group training were evaluated. In particular, we focussed on the teaching methods for adequate chest compression rate and depth. Twenty-one of 30 institutes responded to the questionnaire. The median for hours of theory lessons of CPR was 8h (range: 2-28 h). The median for hours of small group training was 10 (range: 3-40 h). The methods of teaching adequate chest compression rate were instructors' visual estimation in 28.5% of the institutions, watch in 33.3%, metronome in 9.5% and manikins' graphic in 28.5% of institutions. The methods of teaching adequate chest compression depth were instructors' visual estimation in 33.3%, in manikins light indicators in 23.8% and manikins' graphics in 52.3% of institutions. The hours of theoretic lessons and small group training vary widely among different institutes. In one-third of institutions, the instructor's visual estimation was a sole method used to teach adequate chest compression rate and depth. Different technical methods were surprisingly seldom used.

    Full Text Available Not for resuscitation in India still remains an abstract concept with no clear guidelines or legal frame work. Cardiopulmonary resuscitation is a complex medical intervention which is often used inappropriately in hospitalized patients and usually guided by medical decision making rather than patient-directed choices. Patient autonomy still remains a weak concept and relatives are expected to make this big decision in a short time and at a time of great emotional distress. This article outlines concepts around ethics and medico legal aspects of not for resuscitation, especially in Indian setting.

    Full Text Available Objectives: It is commonly known that ergonomics in emergency medical services (EMS is very important. Emergency medical services workers are exposed to different conditions and they should perform a variety of tasks. Material and Methods: The aim of the work has been to analyze the angular position of elbows and forces generated by the upper limbs during cardiopulmonary resuscitation with and without the CPRmeter based on feedback technology. Ten male paramedics and 10 male non-paramedics, in a kneeling position, performed cardiopulmonary resuscitation (CPR on an Ambu Megacode manikin placed on the ground. Measurements were taken after 1 min and 4 min following the beginning of the trial. The angular position of the elbows was evaluated with a BTS Smart DX 7000 motion capture system. Kistler platforms 9286BA were used for measuring forces. Results: In the paramedic group, one statistically significant difference was observed in the mean difference between maximal and minimal right elbow angle in the 1st min without the device vs. the mean difference in the 4th min without the device. In the paramedic group, a 25% force decrease was observed after 4 min of resuscitation in trials without the CPRmeter in comparison to the 1st min. In trials with the CPRmeter, the force parameters were similar in the 1st and 4th min and more stable. No statistically significant differences were noticed in the control group. Conclusions: The CPRmeter has influence on the magnitude of the forces applied by the upper limbs and on the optimization of the rescuer effort during cardiopulmonary resuscitation. The CPRmeter had no influence on the position of the upper part of the kinematic chain. Int J Occup Med Environ Health 2017;30(6:909–916

    To determine the effectiveness of saline-enhanced radiofrequency electrocoagulation in bovine liver tissue Saline-enhanced radiofrequency electrocoagulation (group I), hot saline injection induced by radiofrequency electrocoagulation (group II), and radiofrequency electrocoagulation (group III) were performed in ex vivo bovine liver. Radiofrequency power was 100 and 200 watts, and current was applied for 10, 20, and 30 seconds. Tissue was histopathologically examined for thermal injury. The largest diameter of thermal injury was about 41.0 mm in group I, 12.3 mm in group II and 9.3 mm in group III. The mean diameter of the injury increased with higher wattage in group I and II and with longer procedure time in group I (p<0.05). At corresponding wattage and times, group I showed a larger diameter of thermal injury and more increase in than group II or III (p<0.05). The degree of carbonization was more severe in group III than in groups I and II. Grossly, thermal injury showed a well-defined, relatively spherical configuration without extension along parenchymal interstitium. In an animal model, saline-enhanced radiofrequency electrocoagulation may effectively induce thermal injury, and may thus be another effective tool for use in the treatment of hepatic tumors. Further clinical experience is needed.

    2012-09-01

    Full Text Available Abstract Background Care of the polytrauma patient does not end in the operating room or resuscitation bay. The patient presenting to the intensive care unit following initial resuscitation and damage control surgery may be far from stable with ongoing hemorrhage, resuscitation needs, and injuries still requiring definitive repair. The intensive care physician must understand the respiratory, cardiovascular, metabolic, and immunologic consequences of trauma resuscitation and massive transfusion in order to evaluate and adjust the ongoing resuscitative needs of the patient and address potential complications. In this review, we address ongoing resuscitation in the intensive care unit along with potential complications in the trauma patient after initial resuscitation. Complications such as abdominal compartment syndrome, transfusion related patterns of acute lung injury and metabolic consequences subsequent to post-trauma resuscitation are presented. Methods A non-systematic literature search was conducted using PubMed and the Cochrane Database of Systematic Reviews up to May 2012. Results and conclusion Polytrauma patients with severe shock from hemorrhage and massive tissue injury present major challenges for management and resuscitation in the intensive care setting. Many of the current recommendations for “damage control resuscitation” including the use of fixed ratios in the treatment of trauma induced coagulopathy remain controversial. A lack of large, randomized, controlled trials leaves most recommendations at the level of consensus, expert opinion. Ongoing trials and improvements in monitoring and resuscitation technologies will further influence how we manage these complex and challenging patients.

    Although current resuscitation guidelines are rescuer focused, the opportunity exists to develop patient-centered resuscitation strategies that optimize the hemodynamic response of the individual in the hopes to improve survival. To determine if titrating cardiopulmonary resuscitation (CPR) to blood pressure would improve 24-hour survival compared with traditional CPR in a porcine model of asphyxia-associated ventricular fibrillation (VF). After 7 minutes of asphyxia, followed by VF, 20 female 3-month-old swine randomly received either blood pressure-targeted care consisting of titration of compression depth to a systolic blood pressure of 100 mm Hg and vasopressors to a coronary perfusion pressure greater than 20 mm Hg (BP care); or optimal American Heart Association Guideline care consisting of depth of 51 mm with standard advanced cardiac life support epinephrine dosing (Guideline care). All animals received manual CPR for 10 minutes before first shock. Primary outcome was 24-hour survival. The 24-hour survival was higher in the BP care group (8 of 10) compared with Guideline care (0 of 10); P = 0.001. Coronary perfusion pressure was higher in the BP care group (point estimate +8.5 mm Hg; 95% confidence interval, 3.9-13.0 mm Hg; P < 0.01); however, depth was higher in Guideline care (point estimate +9.3 mm; 95% confidence interval, 6.0-12.5 mm; P < 0.01). Number of vasopressor doses before first shock was higher in the BP care group versus Guideline care (median, 3 [range, 0-3] vs. 2 [range, 2-2]; P = 0.003). Blood pressure-targeted CPR improves 24-hour survival compared with optimal American Heart Association care in a porcine model of asphyxia-associated VF cardiac arrest.

    To assess the effectiveness of supreme laryngeal mask airway (SLMA) over face mask ventilation for preventing need for endotracheal intubation at birth. We report a prospective, randomized, parallel 1:1, unblinded, controlled trial. After a short-term educational intervention on SLMA use, infants ≥34-week gestation and/or expected birth weight ≥1500 g requiring positive pressure ventilation (PPV) at birth were randomized to resuscitation by SLMA or face mask. The primary outcome was the success rate of the resuscitation devices (SLMA or face mask) defined as the achievement of an effective PPV preventing the need for endotracheal intubation. We enrolled 142 patients (71 in SLMA and 71 in face mask group, respectively). Successful resuscitation rate was significantly higher with the SLMA compared with face mask ventilation (91.5% vs 78.9%; P = .03). Apgar score at 5 minutes was significantly higher in SLMA than in face mask group (P = .02). Neonatal intensive care unit admission rate was significantly lower in SLMA than in face mask group (P = .02). No complications related to the procedure occurred. In newborns with gestational age ≥34 weeks and/or expected birth weight ≥1500 g needing PPV at birth, the SLMA is more effective than face mask to prevent endotracheal intubation. The SLMA is effective in clinical practice after a short-term educational intervention. Registered with ClinicalTrials.gov: NCT01963936. Copyright © 2015 Elsevier Inc. All rights reserved.

    Austrian out-of-hospital emergency physicians (OOHEP) undergo mandatory biannual emergency physician refresher courses to maintain their licence. The purpose of this study was to compare different reported emergency skills and knowledge, recommended by the European Resuscitation Council (ERC) guidelines, between OOHEP who work regularly at an out-of-hospital emergency service and those who do not currently work as OOHEP but are licenced. We obtained data from 854 participants from 19 refresher courses. Demographics, questions about their practice and multiple-choice questions about ALS-knowledge were answered and analysed. We particularly explored the application of therapeutic hypothermia, intraosseous access, pocket guide use and knowledge about the participants' defibrillator in use. A multivariate logistic regression analysed differences between both groups of OOHEP. Age, gender, years of clinical experience, ERC-ALS provider course attendance and the self-reported number of resuscitations were control variables. Licenced OOHEP who are currently employed in emergency service are significantly more likely to initiate intraosseous access (OR = 4.013, p ERC-ALS provider course since 2005 have initiated more mild therapeutic hypothermia after successful resuscitation (OR = 1.670, p ERC guidelines better into clinical practice, but more training on life-saving rescue techniques needs to be done to improve knowledge and to raise these rates of application.

    The literature supports minimizing duration of invasive ventilation to decrease lung injury in premature infants. Neonatal Resuscitation Program recommended use of non-invasive ventilation (NIV) in delivery room for infants requiring prolonged respiratory support. To evaluate the impact of implementation of non-invasive ventilation (NIV) using nasal intermittent positive pressure ventilation (NIPPV) for resuscitation in very low birth infants. Retrospective study was performed after NIPPV was introduced in the delivery room and compared with infants receiving face mask to provide positive pressure ventilation for resuscitation of very low birth weight infants prior to its use. Data collected from 119 infants resuscitated using NIPPV and 102 infants resuscitated with a face mask in a single institution. The primary outcome was the need for endotracheal intubation in the delivery room. Data was analyzed using IBM SPSS Statistics software version 24. A total of 31% of infants were intubated in the delivery room in the NIPPV group compared to 85% in the Face mask group (p=rates were 11% in the NIPPV group and 31% in the Face mask group (p<0.001). Epinephrine administration was also lower in NIPPV group (2% vs. 8%; P=0.03). Only 38% infants remained intubated at 24hours of age in the NIPPV group compared to 66% in the Face mask group (p<0.001). Median duration of invasive ventilation in the NIPPV group was shorter (2days) compared to the Face mask group (11days) (p=0.01). The incidence of air-leaks was not significant between the two groups. NIPPV was safely and effectively used in the delivery room settings to provide respiratory support for VLBW infants with less need for intubation, chest compressions, epinephrine administration and subsequent invasive ventilation.

    Newborns who are compromised at birth require rapid attention to stabilize their respiration attempts. Lack of knowledge regarding basic newborn resuscitation is a contributing factor to poor newborn health outcomes and increased mortality. The purpose of this study was to explore Jordanian midwives' experiences, education, and support needs to competently perform basic newborn resuscitation. Qualitative descriptive methodology was used to analyze a convenience sample of 20 midwives. A thematic approach was used to analyze the data. Participants discussed their experiences of basic newborn resuscitation including knowledge, skills, and barriers and suggested solutions to improve practice. Four themes were revealed: lack of knowledge and skills in newborn resuscitation, organizational constraints, inadequate teamwork, and educational needs. The midwives perceived that their ability to perform newborn resuscitation was hindered by lack of knowledge and skills in newborn resuscitation, organizational constraints (such as lack of equipment), and poor co-ordination and communication among team members. © The Author(s) 2015.

    Resuscitation with polynitroxylated pegylated hemoglobin (PNPH), a pegylated bovine hemoglobin decorated with nitroxides, eliminated the need for fluid administration, reduced intracranial pressure (ICP) and brain edema, and produced neuroprotection in vitro and in vivo versus Lactated Ringer's solution (LR) in experimental traumatic brain injury (TBI) plus hemorrhagic shock (HS). We hypothesized that resuscitation with PNPH would improve acute physiology versus whole blood after TBI+HS and would be safe and effective across a wide dosage range. Anesthetized mice underwent controlled cortical impact and severe HS to mean arterial pressure (MAP) of 25-27 mm Hg for 35 min, then were resuscitated with PNPH, autologous whole blood, or LR. Markers of acute physiology, including mean arterial blood pressure (MAP), heart rate (HR), blood gases/chemistries, and brain oxygenation (PbtO 2 ), were monitored for 90 min on room air followed by 15 min on 100% oxygen. In a second experiment, the protocol was repeated, except mice were resuscitated with PNPH with doses between 2 and 100 mL/kg. ICP and 24 h %-brain water were evaluated. PNPH-resuscitated mice had higher MAP and lower HR post-resuscitation versus blood or LR (p < 0.01). PNPH-resuscitated mice, versus those resuscitated with blood or LR, also had higher pH and lower serum potassium (p < 0.05). Blood-resuscitated mice, however, had higher PbtO 2 versus those resuscitated with LR and PNPH, although PNPH had higher PbtO 2 versus LR (p < 0.05). PNPH was well tolerated across the dosing range and dramatically reduced fluid requirements in all doses-even 2 or 5 mL/kg (p < 0.001). ICP was significantly lower in PNPH-treated mice for most doses tested versus in LR-treated mice, although %-brain water did not differ between groups. Resuscitation with PNPH, versus resuscitation with LR or blood, improved MAP, HR, and ICP, reduced acidosis and hyperkalemia, and was well tolerated and effective

    Full Text Available Background: One dilemma in the end-of-life care is making decisions for conducting cardiopulmonary resuscitation (CPR. This dilemma is perceived in different ways due to the influence of culture and religion. This study aimed to understand the experiences of CPR team members about the do-not-resuscitate order. Methods: CPR team members were interviewed, and data were analyzed using a conventional content analysis method. Results: Three categories and six subcategories emerged: “The dilemma between revival and suffering” with the subcategories of “revival likelihood” and “death as a cause for comfort;” “conflicting situation” with the subcategories of “latent decision” and “ambivalent order;” and “low-quality CPR” with the subcategories of “team member demotivation” and “disrupting CPR performance.” Conclusion: There is a need for the development of a contextual guideline, which is required for respecting the rights of patients and their families and providing legal support to health-care professionals during CPR.

    Hypoxemia and tissue ischemia during hemorrhage as well as formation of oxygen and nitrogen radicals during resuscitation promote hyperinflammation and, consequently, trigger severe multiple-organ-failure (MOF). Individuals diagnosed with stress-related disorders or reporting a life history of psychosocial stress are characterized by chronic low-grade inflammation and a reduced glucocorticoid (GC) signaling. We hypothesized that exposure to chronic psychosocial stress during adulthood prior to hemorrhagic shock increases oxidative/nitrosative stress and therefore the risk of developing MOF in mice. To induce chronic psychosocial stress linked to mild immune activation and reduced GC signaling in male mice, the chronic subordinate colony housing (CSC) paradigm was employed. Single-housed (SHC) mice were used as controls. Subsequently, CSC and SHC mice were exposed to hemorrhagic shock following resuscitation to investigate the effects of prior psychosocial stress load on survival, organ function, metabolism, oxidative/nitrosative stress, and inflammatory readouts. An increased adrenal weight in CSC mice indicates that the stress paradigm reliably worked. However, no effect of prior psychosocial stress on outcome after subsequent hemorrhage and resuscitation could be detected. Chronic psychosocial stress during adulthood is not sufficient to promote hemodynamic complications, organ dysfunction, metabolic disturbances and did not increase the risk of MOF after subsequent hemorrhage and resuscitation. Intravenous norepinephrine to keep target hemodynamics might have led to a certain level of oxidative stress in both groups and, therefore, disguised potential effects of chronic psychosocial stress on organ function after hemorrhagic shock in the present murine trauma model.

    We have previously shown that the extent of traumatic brain injury (TBI) in large animal models can be reduced with early infusion of fresh frozen plasma (FFP), but the precise mechanisms remain unclear. In this study, we investigated whether resuscitation with FFP or normal saline differed in th...... in their effects on cerebral metabolism and excitotoxic secondary brain injury in a model of polytrauma, TBI, and hemorrhagic shock....

  12. Effect of Salinity on Germination and Its Relationship with Vegetative growth in Bromus danthoniae Genotypes from Saline and Non-Saline Areas of Iran

    Full Text Available Bromus danthoniae Trin. is an annual grass species that is well adapted to harsh climates and could be considered as an important genetic resources for tolerance to environmental stresses such as salinity. In this study, 24 genotypes collected from Ilam, Kurdistan, Kermanshah (non-saline areas and West Azerbaijan (saline area: shores of Uremia Salt Lake provinces of Iran were investigated at the germination stage under salt treatments with concentrations of 0, 60, 120, 180, 240 and 300 mM sodium chloride. Germination percentage, germination rate index, seed vigor, root length, shoot length and seedling fresh and dry weights were measured. In addition, the relationship between the percentage of germination in 300 mM sodium chloride and the survival rate (% after four weeks in 350 mM sodium chloride at the vegetative stage was evaluated. The results of analysis of variance showed that salinity treatments caused significant reductions in all the studied traits. Genotypic variation and the interaction of genotype × salt treatments were also significant. Genotypes USLN3 and KER4 were found to be the most tolerant and sensitive genotypes to salinity stress, with 13% and 98% reduction in germination percentage at 300 mM NaCl, respectively. Cluster analysis divided the genotypes into three groups, with one group containing only tolerant genotypes from Uremia Salt Lake, another one comprising only sensitive genotypes from non-saline regions, and the third one containing genotypes from both regions. The correlation between the germination percentage and the survival rate at the vegetative stage was not significant, indicating that different mechanisms are, perhaps, responsible for salinity tolerance at the germination and vegetative stages in B. danthoniae.

    OBJECTIVE: This study sought to determine whether hypertonic saline (HTS) infusion modulates the host response to bacterial challenge. METHODS: Sepsis was induced in 30 Balb-C mice by intraperitoneal injection of Escherichia coli (5 x 107 organisms per animal). In 10 mice, resuscitation was performed at 0 and 24 hours with a 4 mL\\/kg bolus of HTS (7.5% NaCl), 10 animals received 4 mL\\/kg of normal saline (0.9% NaCl), and the remaining animals received 30 mL\\/kg of normal saline. Samples of blood, spleen, and lung were cultured at 8 and 36 hours. Polymorphonucleocytes were incubated in isotonic or hypertonic medium before culture with E. coli. Phagocytosis was assessed by flow cytometry, whereas intracellular bacterial killing was measured after inhibition of phagocytosis with cytochalasin B. Intracellular formation of free radicals was assessed by the molecular probe CM-H(2)DCFDA. Mitogen-activated protein (MAP) kinase p38 and ERK-1 phosphorylation, and nuclear factor kappa B (NFkappaB) activation were determined. Data are represented as means (SEM), and an analysis of variance test was performed to gauge statistical significance. RESULTS: Significantly reduced bacterial culture was observed in the animals resuscitated with HTS when compared with their NS counterparts, in blood (51.8 +\\/- 4.3 vs. 82.0 +\\/- 3.3 and 78.4 +\\/- 4.8, P = 0.005), lung (40.0 +\\/- 4.1 vs. 93.2 +\\/- 2.1 and 80.9 +\\/- 4.7, P = 0.002), and spleen (56.4 +\\/- 3.8 vs. 85.4 +\\/- 4.2 and 90.1 +\\/- 5.9, P = 0.05). Intracellular killing of bacteria increased markedly (P = 0.026) and superoxide generation was enhanced upon exposure to HTS (775.78 +\\/- 23.6 vs. 696.57 +\\/- 42.2, P = 0.017) despite inhibition of MAP kinase and NFkappaB activation. CONCLUSIONS: HTS significantly enhances intracellular killing of bacteria while attenuating receptor-mediated activation of proinflammatory cascades.

    Most newborns are born vigorous and do not require neonatal resuscitation. However, about 10% of newborns require some type of resuscitative assistance at birth. Although the vast majority will require just assisted lung aeration, about 1% requires major interventions such as intubation, chest compressions, or medications. Recently, new evidence has prompted modifications in the international cardiopulmonary resuscitation (CPR) guidelines for both neonatal, paediatric and adult patients. Perinatal and neonatal health care providers must be aware of these changes in order to provide the most appropriate and evidence-based emergency interventions for newborns in the delivery room. The aim of this article is to provide an overview of the main recommended changes in neonatal resuscitation at birth, according to the publication of the international Liaison Committee on Resuscitation (ILCOR) in the CoSTR document (based on evidence of sciences) and the new 2010 guidelines released by the European Resuscitation Council (ERC), the American Heart Association (AHA), and the American Academy of Pediatrics (AAP).

    Rationale: Although current resuscitation guidelines are rescuer focused, the opportunity exists to develop patient-centered resuscitation strategies that optimize the hemodynamic response of the individual in the hopes to improve survival. Objectives: To determine if titrating cardiopulmonary resuscitation (CPR) to blood pressure would improve 24-hour survival compared with traditional CPR in a porcine model of asphyxia-associated ventricular fibrillation (VF). Methods: After 7 minutes of asphyxia, followed by VF, 20 female 3-month-old swine randomly received either blood pressure–targeted care consisting of titration of compression depth to a systolic blood pressure of 100 mm Hg and vasopressors to a coronary perfusion pressure greater than 20 mm Hg (BP care); or optimal American Heart Association Guideline care consisting of depth of 51 mm with standard advanced cardiac life support epinephrine dosing (Guideline care). All animals received manual CPR for 10 minutes before first shock. Primary outcome was 24-hour survival. Measurements and Main Results: The 24-hour survival was higher in the BP care group (8 of 10) compared with Guideline care (0 of 10); P = 0.001. Coronary perfusion pressure was higher in the BP care group (point estimate +8.5 mm Hg; 95% confidence interval, 3.9–13.0 mm Hg; P < 0.01); however, depth was higher in Guideline care (point estimate +9.3 mm; 95% confidence interval, 6.0–12.5 mm; P < 0.01). Number of vasopressor doses before first shock was higher in the BP care group versus Guideline care (median, 3 [range, 0–3] vs. 2 [range, 2–2]; P = 0.003). Conclusions: Blood pressure–targeted CPR improves 24-hour survival compared with optimal American Heart Association care in a porcine model of asphyxia-associated VF cardiac arrest. PMID:25321490

  17. Human factors in resuscitation: Lessons learned from simulator studies

    Directory of Open Access Journals (Sweden)

    Hunziker S

    2010-01-01

    Full Text Available Medical algorithms, technical skills, and repeated training are the classical cornerstones for successful cardiopulmonary resuscitation (CPR. Increasing evidence suggests that human factors, including team interaction, communication, and leadership, also influence the performance of CPR. Guidelines, however, do not yet include these human factors, partly because of the difficulties of their measurement in real-life cardiac arrest. Recently, clinical studies of cardiac arrest scenarios with high-fidelity video-assisted simulations have provided opportunities to better delineate the influence of human factors on resuscitation team performance. This review focuses on evidence from simulator studies that focus on human factors and their influence on the performance of resuscitation teams. Similar to studies in real patients, simulated cardiac arrest scenarios revealed many unnecessary interruptions of CPR as well as significant delays in defibrillation. These studies also showed that human factors play a major role in these shortcomings and that the medical performance depends on the quality of leadership and team-structuring. Moreover, simulated video-taped medical emergencies revealed that a substantial part of information transfer during communication is erroneous. Understanding the impact of human factors on the performance of a complex medical intervention like resuscitation requires detailed, second-by-second, analysis of factors involving the patient, resuscitative equipment such as the defibrillator, and all team members. Thus, high-fidelity simulator studies provide an important research method in this challenging field.

    2014-05-01

    The Trauma Hemostasis and Oxygenation Research Network held its third annual Remote Damage Control Resuscitation Symposium in June 2013 in Bergen, Norway. The Trauma Hemostasis and Oxygenation Research Network is a multidisciplinary group of investigators with a common interest in improving outcomes and safety in patients with severe traumatic injury. The network's mission is to reduce the risk of morbidity and mortality from traumatic hemorrhagic shock, in the prehospital phase of resuscitation through research, education, and training. The concept of remote damage control resuscitation is in its infancy, and there is a significant amount of work that needs to be done to improve outcomes for patients with life-threatening bleeding secondary to injury. The prehospital phase of resuscitation is critical in these patients. If shock and coagulopathy can be rapidly identified and minimized before hospital admission, this will very likely reduce morbidity and mortality. This position statement begins to standardize the terms used, provides an acceptable range of therapeutic options, and identifies the major knowledge gaps in the field.

    2012-07-01

    Guidelines for basic and advanced paediatric cardiopulmonary resuscitation (CPR) have been revised by Australian and New Zealand Resuscitation Councils. Changes encourage CPR out-of-hospital and aim to improve the quality of CPR in-hospital. Features of basic CPR include: omission of abdominal thrusts for foreign body airway obstruction; commencement with chest compression followed by ventilation in a ratio of 30:2 or compression-only CPR if the rescuer is unwilling/unable to give expired-air breathing when the victim is 'unresponsive and not breathing normally'. Use of automated external defibrillators is encouraged. Features of advanced CPR include: prevention of cardiac arrest by rapid response systems; restriction of pulse palpation to 10 s to diagnosis cardiac arrest; affirmation of 15:2 compression-ventilation ratio for children and for infants other than newly born; initial bag-mask ventilation before tracheal intubation; a single direct current shock of 4 J/kg for ventricular fibrillation (VF) and pulseless ventricular tachycardia followed by immediate resumption of CPR for 2 min without analysis of cardiac rhythm and avoidance of unnecessary interruption of continuous external cardiac compressions. Monitoring of exhaled carbon dioxide is recommended to detect non-tracheal intubation, assess quality of CPR, and to help match ventilation to reduced cardiac output. The intraosseous route is recommended if immediate intravenous access is impossible. Amiodarone is strongly favoured over lignocaine for refractory VF and adrenaline over atropine for severe bradycardia, asystole and pulseless electrical activity. Family presence at resuscitation is encouraged. Therapeutic hypothermia is acceptable after resuscitation to improve neurological outcome. Extracorporeal circulatory support for in-hospital cardiac arrest may be used in equipped centres. © 2011 The Authors.

    Current neonatal resuscitation guidelines recommend 3:1 compression:ventilation (C:V) ratio. Recently, animal studies reported that continuous chest compressions (CC) during a sustained inflation (SI) significantly improved return of spontaneous circulation (ROSC). The approach of CC during SI (CC+SI) has not been examined in the delivery room during neonatal resuscitation. It is a feasibility study to compare CC+SI versus 3:1 C:V ratio during neonatal resuscitation in the delivery room. We hypothesised that during neonatal resuscitation, CC+SI will reduce the time to ROSC. Our aim was to examine if CC+SI reduces ROSC compared with 3:1 C:V CPR in preterm infants rate of 90/min during an SI with a duration of 20 s (CC+SI). After 20 s, the SI was interrupted for 1 s and the next SI was started for another 20 s until ROSC. Infants in the '3:1 group' received CC using 3:1 C:V ratio until ROSC. Overall the mean (SD) time to ROSC was significantly shorter in the CC+SI group with 31 (9) s compared with 138 (72) s in the 3:1 C:V group (p=0.011). CC+SI is feasible in the delivery room.

    Full Text Available Objective: To study the effect of intrauterine resuscitation on umbilical cord blood parameters of fullterm fetal distress and neonatal nerve function. Methods: A total of 74 cases of women who gave birth in Gynecology and Obstetrics Department of our hospital and had fetal distress during labor from February 2008 to October 2010 were selected for study and randomly divided into two groups, observation group received intrauterine resuscitation, control group received conventional treatment, and then contents of umbilical arterial blood gas parameters and cytokines of two groups of patients, contents of serum nerve injury molecules of neonates as well as neonatal asphyxia condition and nerve function were compared. Results: pH value, PO2 and HCO3- in umbilical cord blood of observation group were higher than those of control group, and PCO2 and BE absolute value were lower than those of control group; IL-6, IL-8 and IFN-γ contents in umbilical arterial blood and umbilical venous blood of observation group of patients were significantly lower than those of control group; 1 d, 3 d, 5 d and 7 d after birth, serum NSE and S-100 protein contents of observation group of neonates were significantly lower than those of control group; neonatal asphyxia condition and nerve function were better than those of control group. Conclusion: Intrauterine resuscitation can improve intrauterine fetal anoxia and reduce acidosis while reduce neonatal nerve function injury and prevent neonatal asphyxia, and it is an ideal method to treat full-term fetal distress.

    The focused assessment with sonography in trauma (FAST) examination is an important screening tool in the evaluation of blunt trauma patients. To describe a case of a hemodynamically unstable polytrauma patient with positive FAST due to fluid resuscitation after blunt trauma. We describe a case of a hemodynamically unstable polytrauma patient who underwent massive volume resuscitation prior to transfer from a community hospital to a trauma center. On arrival at the receiving institution, the FAST examination was positive for free intraperitoneal fluid, but no hemoperitoneum or significant intra-abdominal injuries were found during laparotomy. In this case, it is postulated that transudative intraperitoneal fluid secondary to massive volume resuscitation resulted in a positive FAST examination. This case highlights potential issues specific to resuscitated trauma patients with prolonged transport times. Further study is likely needed to assess what changes, if any, should be made in algorithms to address the effect of prior resuscitative efforts on the test characteristics of the FAST examination.

    Making decision on not to resuscitate is a confusing, conflicting and complex issue and depends on each country's culture and customs. Therefore, each country needs to take action in accordance with its cultural, ethical, religious and legal contexts to develop guidelines in this regard. Since the majority of Iran's people are Muslims, and in Islam, the human life is considered sacred, based on the values of the community, an Iranian Islamic agenda needs to be developed not taking measures about resuscitation of dying patients. It is necessary to develop an Iranian Islamic guidelines package in order to don't resuscitate in dying patients.

    Both commercial aviation and resuscitation are complex activities in which team members must respond to unexpected emergencies in a consistent, high quality manner. Lives are at stake in both activities and the two disciplines have similar leadership structures, standard setting processes, training methods, and operational tools. Commercial aviation crews operate with remarkable consistency and safety, while resuscitation team performance and outcomes are highly variable. This commentary provides the perspective of two physician-pilots showing how commercial aviation training, operations, and safety principles can be adapted to resuscitation team training and performance.

    2006-12-01

    Cardiac arrest and cardiopulmonary resuscitation is an event of global myocardial ischemia and reperfusion, which is associated with severe postresuscitation myocardial dysfunction and fatal outcome. Evidence has demonstrated that mammalian hibernation is triggered by cyclic variation of a delta-opiate-like compound in endogenous serum, during which the myocardial metabolism is dramatically reduced and the myocardium tolerates the stress of ischemia and reperfusion without overt ischemic and reperfusion injury. Previous investigations also proved that the delta-opioid agonist elicited the cardioprotection in a model of regional ischemic intact heart or myocyte. Accordingly, we were prompted to search for an alternative intervention of pharmacologically induced myocardial hibernation that would result in rapid reductions of myocardial metabolism and therefore minimize the myocardial ischemic and reperfusion injury during cardiac arrest and cardiopulmonary resuscitation. Prospective, controlled laboratory study. University-affiliated research laboratory. In the series of studies performed in the established rat and pig model of cardiac arrest and cardiopulmonary resuscitation, the delta-opioid receptor agonist, pentazocine, was administered during ventricular fibrillation. : The myocardial metabolism reflected by the concentration of lactate, or myocardial tissue PCO2 and PO2, is dramatically reduced during cardiac arrest and cardiopulmonary resuscitation. These are associated with less severe postresuscitation myocardial dysfunction and longer duration of postresuscitation survival. delta-Opioid-induced pharmacologic myocardial hibernation is an option to minimize the myocardial ischemia and reperfusion injury during cardiac arrest and cardiopulmonary resuscitation.

    In-hospital, family-witnessed cardiopulmonary resuscitation of adults has been found to help patients' family members deal with the short- and long-term emotional consequences of resuscitation. Because of its benefits, many national and international nursing and medical organizations officially recommend this practice. Research, however, shows that family-witnessed resuscitation is not widely implemented in clinical practice, and health care professionals generally do not favour this recommendation. To describe and provide an initial basis for understanding health care professionals' views and perspectives regarding the implementation of an in-hospital, family-witnessed adult resuscitation practice in two European countries. An inductive qualitative approach was used in this study. Finnish (n = 93) and Polish (n = 75) emergency and intensive care nurses and physicians provided written responses to queries regarding their personal observations, concerns and comments about in-hospital, family-witnessed resuscitation of an adult. Data were analysed using inductive thematic analysis. The study analysis yielded five themes characterizing health care professionals' main concerns regarding family-witnessed resuscitation: (1) family's horror, (2) disturbed workflow (3) no support for the family, (4) staff preparation and (5) situation-based decision. Despite existing evidence revealing the positive influence of family-witnessed resuscitation on patients, relatives and cardiopulmonary resuscitation process, Finnish and Polish health care providers cited a number of personal and organizational barriers against this practice. The results of this study begin to examine reasons why family-witnessed resuscitation has not been widely implemented in practice. In order to successfully apply current evidence-based resuscitation guidelines, provider concerns need to be addressed through educational and organizational changes. This study identified important implementation

    Saline giants are vast marine evaporite deposits that currently have no modern analogues and remain one of the most enigmatic of chemical sedimentary rocks. The Mississippian Windsor Group (ca. 345 Ma), Maritimes Basin, Atlantic Canada is a saline giant that consists of two evaporite-rich sedimentary sequences that are subdivided into five subzones. Sequence 1 is composed almost entirely of thick halite belonging to Subzone A (Osagean). Sequence 2 is in unconformable contact and comprised of stacked carbonate-evaporite peritidal cycles of Subzones B through E (Meramecian). Subzone B, the focus of research herein, documents the transition from wholly evaporitic to open marine conditions and thus, preserves an exceptional window into the processes forming saline giants. Lithofacies stacking patterns in Subzone B reveal that higher-order fluctuations in relative sea level produced nine stacked parasequences interpreted to reflect high frequency glacioeustatic oscillations during the onset of the Late Paleozoic Ice Age. Each parasequence reflects progradation of intertidal and sabkha sediments over subtidal carbonate and evaporite deposits. Dissimilarities in cycle composition between sub-basins imply the development of contrasting brine chemistries from differing recharge rates with the open ocean. What the Windsor Group shows is that evaporite type is ostensibly linked to the amplitude and frequency of sea level rise and fall during deposition. True saline giants, like the basinwide evaporites of Sequence 1, apparently require low amplitude, long frequency changes in sea level to promote the development of stable brine pools that are only periodically recharged with seawater. By contrast, the high amplitude, short frequency glacioeustatic variability in sea level that controlled the accumulation of peritidal evaporites in Subzone B produce smaller, subeconomic deposits with more complex facies relationships.

    Simplifying the learning of cardiopulmonary resuscitation (CPR) is advocated to improve skill acquisition and retention. A simplified CPR training programme focusing on continuous chest compression, with a simple landmark tracing technique, was introduced to laypeople. The study aimed to examine the effectiveness of the simplified CPR training in improving lay rescuers' CPR performance as compared to standard CPR. A total of 85 laypeople (aged 21-60 years) were recruited and randomly assigned to undertake either a two-hour simplified or standard CPR training session. They were tested two months after the training on a simulated cardiac arrest scenario. Participants' performance on the sequence of CPR steps was observed and evaluated using a validated CPR algorithm checklist. The quality of chest compression and ventilation was assessed from the recording manikins. The simplified CPR group performed significantly better on the CPR algorithm when compared to the standard CPR group (p CPR. However, a significantly higher number of compressions and proportion of adequate compressions was demonstrated by the simplified group than the standard group (p CPR group than in the standard CPR group (p CPR by focusing on continuous chest compressions, with simple hand placement for chest compression, could lead to better acquisition and retention of CPR algorithms, and better quality of chest compressions than standard CPR.

    To measure the effect of a 1-day team training course for pediatric interprofessional resuscitation team members on adherence to Pediatric Advanced Life Support guidelines, team efficiency, and teamwork in a simulated clinical environment. Multicenter prospective interventional study. Four tertiary-care children's hospitals in Canada from June 2011 to January 2015. Interprofessional pediatric resuscitation teams including resident physicians, ICU nurse practitioners, registered nurses, and registered respiratory therapists (n = 300; 51 teams). A 1-day simulation-based team training course was delivered, involving an interactive lecture, group discussions, and four simulated resuscitation scenarios, each followed by a debriefing. The first scenario of the day (PRE) was conducted prior to any team training. The final scenario of the day (POST) was the same scenario, with a slightly modified patient history. All scenarios included standardized distractors designed to elicit and challenge specific teamwork behaviors. Primary outcome measure was change (before and after training) in adherence to Pediatric Advanced Life Support guidelines, as measured by the Clinical Performance Tool. Secondary outcome measures were as follows: 1) change in times to initiation of chest compressions and defibrillation and 2) teamwork performance, as measured by the Clinical Teamwork Scale. Correlation between Clinical Performance Tool and Clinical Teamwork Scale scores was also analyzed. Teams significantly improved Clinical Performance Tool scores (67.3-79.6%; p Teamwork Scale scores (56.0-71.8%; p Teamwork Scale (R = 0.281; p teamwork during simulated pediatric resuscitation. A positive correlation between clinical and teamwork performance suggests that effective teamwork improves clinical performance of resuscitation teams.

    After years of advocating ABC (Airway-Breathing-Circulation), current guidelines of cardiopulmonary resuscitation (CPR) recommend CAB (Circulation-Airway-Breathing). This trial compared ABC with CAB as initial approach to CPR from the arrival of rescuers until the completion of the first resuscitation cycle. 108 teams, consisting of two physicians each, were randomized to receive a graphical display of either the ABC algorithm or the CAB algorithm. Subsequently teams had to treat a simulated cardiac arrest. Data analysis was performed using video recordings obtained during simulations. The primary endpoint was the time to completion of the first resuscitation cycle of 30 compressions and two ventilations. The time to execution of the first resuscitation measure was 32 ± 12 seconds in ABC teams and 25 ± 10 seconds in CAB teams (P = 0.002). 18/53 ABC teams (34%) and none of the 55 CAB teams (P = 0.006) applied more than the recommended two initial rescue breaths which caused a longer duration of the first cycle of 30 compressions and two ventilations in ABC teams (31 ± 13 vs.23 ± 6 sec; P = 0.001). Overall, the time to completion of the first resuscitation cycle was longer in ABC teams (63 ± 17 vs. 48 ± 10 sec; P ABC with an earlier start of CPR and a shorter time to completion of the first 30:2 resuscitation cycle. These findings endorse the change from ABC to CAB in international resuscitation guidelines.

    Handoffs for neonatal resuscitation involve communicating critical delivery information (CDI). The authors sought to achieve ≥95% communication of CDI during resuscitation team requests. CDI included name of caller, urgency of request, location of delivery, gestation of fetus, status of amniotic fluid, and indication for presence of the resuscitation team. Three interventions were implemented: verbal scripted handoff, Spök text messaging, and Engage text messaging. Percentages of CDI communications were analyzed using statistical process control. Following implementation of Engage, the communication of all CDI, except for indication, was ≥95%; communication of indication occurred 93% of the time. Control limits for most CDI were narrower with Engage, indicating greater reliability of communication compared to the verbal handoff and Spök. Delayed resuscitation team arrival, a countermeasure, was not higher with text messaging compared to verbal handoff ( P = 1.00). Text messaging improved communication during high-risk deliveries, and it may represent an effective tool for other delivery centers.

    Cardiopulmonary resuscitation is undertaken more than 250,000 times annually in the United States. This study was undertaken to determine knowledge and opinions of the general public regarding cardiopulmonary resuscitation. Validated multisite community-based cross-sectional survey. Knowledge and opinions about resuscitative practices and outcomes, using hypothetical clinical scenarios and other social, spiritual, and environmental considerations. Among 1831 participants representing 38 states, markedly inaccurate perceptions of cardiac arrest were reported. Participants' mean estimate of predicted survival rate after cardiac arrest was 54% (median 50%, IQR 35-75%), and mean estimated duration of resuscitative efforts in the ED was 28min (median 15min; IQR 10-30). Projected age and health status were independent predictors of resuscitation preferences in a series of 4 hypothetical scenarios. Participants indicated that physicians should consider patient and family wishes as the most important factors when making resuscitation decisions. Participants considered advanced technology and physician communication to be the most important actions during attempted resuscitation. Inaccurate perceptions regarding resuscitation and survival rates exist among the lay public. Participants indicated strong preferences regarding resuscitation and advance directives.

    2014-04-01

    This multiorganizational literature review was undertaken to provide an evidence base for determining whether or not recommendations for out-of-hospital termination of resuscitation could be made for children who are victims of traumatic cardiopulmonary arrest. Although there is increasing acceptance of out-of-hospital termination of resuscitation for adult traumatic cardiopulmonary arrest when there is no expectation of a good outcome, children are routinely excluded from state termination-of-resuscitation protocols. The decision to withhold resuscitative efforts in a child under specific circumstances (decapitation or dependent lividity, rigor mortis, etc) is reasonable. If there is any doubt as to the circumstances or timing of the traumatic cardiopulmonary arrest, under the current status of limiting termination of resuscitation in the field to persons older than 18 years in most states, resuscitation should be initiated and continued until arrival to the appropriate facility. If the patient has arrested, resuscitation has already exceeded 30 minutes, and the nearest facility is more than 30 minutes away, involvement of parents and family of these children in the decision-making process with assistance and guidance from medical professionals should be considered as part of an emphasis on family-centered care, because the evidence suggests that either death or a poor outcome is inevitable.

    No study has tested a Crisis Resource Management prompt on resuscitation performance. We conducted a feasibility, unblinded, parallel-group, randomised controlled trial at one Australian paediatric hospital (June-September 2014). Eligible participants were any doctor, nurse, or nurse manager who would normally be involved in a Medical Emergency Team simulation. The unit of block randomisation was one of six scenarios (3 control:3 intervention) with or without a verbal prompt. The primary outcomes tested the feasibility and utility of the intervention and data collection tools. The secondary outcomes measured resuscitation quality and team performance. Data were analysed from six resuscitation scenarios (n=49 participants); three control groups (n=25) and three intervention groups (n=24). The ability to measure all data items on the data collection tools was hindered by problems with the recording devices both in the mannequins and the video camera. For a pilot study, greater training for the prompt role and pre-briefing participants about assessment of their cardio-pulmonary resuscitation quality should be undertaken. Data could be analysed in real time with independent video analysis to validate findings. Two cameras would strengthen reliability of the methods.

    Full Text Available Cardiopulmonary arrest is a medical emergency in which the lapse of time between event onset and the initiation of measures of basic and advanced support, as well as the correct care based on specific protocols for each clinical situation, constitute decisive factors for a successful therapy. Cardiopulmonary arrest care cannot be restricted to the hospital setting because of its fulminant nature. This necessitates the creation of new concepts, strategies and structures, such as the concept of life chain, cardio-pulmonary resuscitation courses for professionals who work in emergency medical services, the automated external defibrillator, the implantable cardioverter-defibrillator, and mobile intensive care units, among others. New concepts, strategies and structures motivated by new advances have also modified the treatment and improved the results of cardiopulmonary resuscitation in the hospital setting. Among them, we can cite the concept of cerebral resuscitation, the application of the life chain, the creation of the universal life support algorithm, the adjustment of drug doses, new techniques - measure of the end-tidal carbon dioxide levels and of the coronary perfusion pressure - and new drugs under research.

    Traumatic brain injury (TBI) and hemorrhagic shock (HS) are the leading causes of traumatic death worldwide and particularly on the battlefield. They are especially challenging when present simultaneously (polytrauma), and clear blood pressure end points during fluid resuscitation are not well described for this situation. The goal of this study is to evaluate for any benefit of increasing blood pressure using a vasopressor on brain blood flow during initial fluid resuscitation in a swine polytrauma model. We used a swine polytrauma model with simultaneous TBI, femur fracture, and HS with uncontrolled noncompressible internal bleeding from an aortic tear injury. Five animals were assigned to each of three experimental groups (hydroxyethyl starch only [HES], HES + 0.4 U/kg vasopressin, and no fluid resuscitation [No Fluids]). Fluids were given as two 10 mL/kg boluses according to tactical field care guidelines. Primary outcomes were mean arterial blood pressure (MAP) and brain blood flow at 60 min. Secondary outcomes were blood flows in the heart, intestine, and kidney; arterial blood lactate level; and survival at 6 hr. Organ blood flow was measured using injection of colored microspheres. Five animals were tested in each of the three groups. There was a statistically significant increase in MAP with vasopressin compared with other experimental groups, but no significant increase in brain blood flow during the first 60 min of resuscitation. The vasopressin group also exhibited greater total internal hemorrhage volume and rate. There was no difference in survival at 6 hours. In this experimental swine polytrauma model, increasing blood pressure with vasopressin did not improve brain perfusion, likely due to increased internal hemorrhage. Effective hemostasis should remain the top priority for field treatment of the polytrauma casualty with TBI.

    Early goal-directed therapy (EGDT) is recommended in international guidance for the resuscitation of patients presenting with early septic shock. However, adoption has been limited and uncertainty remains over its clinical effectiveness and cost-effectiveness. The primary objective was to estimate the effect of EGDT compared with usual resuscitation on mortality at 90 days following randomisation and on incremental cost-effectiveness at 1 year. The secondary objectives were to compare EGDT with usual resuscitation for requirement for, and duration of, critical care unit organ support; length of stay in the emergency department (ED), critical care unit and acute hospital; health-related quality of life, resource use and costs at 90 days and at 1 year; all-cause mortality at 28 days, at acute hospital discharge and at 1 year; and estimated lifetime incremental cost-effectiveness. A pragmatic, open, multicentre, parallel-group randomised controlled trial with an integrated economic evaluation. Fifty-six NHS hospitals in England. A total of 1260 patients who presented at EDs with septic shock. EGDT (n = 630) or usual resuscitation (n = 630). Patients were randomly allocated 1 : 1. All-cause mortality at 90 days after randomisation and incremental net benefit (at £20,000 per quality-adjusted life-year) at 1 year. Following withdrawals, data on 1243 (EGDT, n = 623; usual resuscitation, n = 620) patients were included in the analysis. By 90 days, 184 (29.5%) in the EGDT and 181 (29.2%) patients in the usual-resuscitation group had died [p = 0.90; absolute risk reduction -0.3%, 95% confidence interval (CI) -5.4 to 4.7; relative risk 1.01, 95% CI 0.85 to 1.20]. Treatment intensity was greater for the EGDT group, indicated by the increased use of intravenous fluids, vasoactive drugs and red blood cell transfusions. Increased treatment intensity was reflected by significantly higher Sequential Organ Failure Assessment scores and more advanced

    This study investigated the effect of increasing numbers of training sessions in cardiopulmonary resuscitation (CPR) on trainees' attitude and CPR quality. Cardiopulmonary resuscitation training for hospital employees was held every year from 2006 to 2010. Participants were recruited among the trainees in 2010. The trainees' attitudes toward CPR were surveyed by questionnaire, and the quality of their CPR was measured using 5-cycle 30:2 CPR on a manikin. Participants were categorized according to the number of consecutive CPR training sessions as T1 (only 2010), T2 (2009 and 2010), T3 (from 2008 to 2010) and T4-5 (from 2006 or 2007 to 2010). The trainee attitude and CPR quality were compared among the 4 groups. Of 923 CPR trainees, 267 were enrolled in the study. There was significant increase in willingness to start CPR and confidence in chest compression and mouth-to-mouth ventilation (MTMV) with increasing number of CPR training sessions attended (especially for ≥ 3 sessions). There was a significant increase in mean compression depth and decrease in percentage of chest compressions with depth of less than 38 mm in the T3 and T4-5 compared with the T1 and T2. No-flow time decreased significantly, and the percentage of MTMV with visible chest rise increased, as the number of training sessions increased. Repeated CPR training improved trainees' attitude and CPR quality. Because the number of training sessions increased (≥3), the willingness to start CPR and the confidence in skills increased significantly, and chest compression depth, no-flow time, and MTMV improved.

    We hypothesized that recent hands-on practice for cardiopulmonary resuscitation (CPR) would be strongly associated with a higher likelihood of self-efficacy in bystander CPR among laypersons according to age and gender group. We used the National Korean Community Health Survey database of 228921 representatively sampled responders from 253 counties in 2012. Laypersons who had previous CPR training were eligible. Exposure variables were having had CPR training with hands-on practice session with a manikin (Practical-CPR-Training) and CPR training within the last 2 years (Recent-CPR-Training). Primary outcome was self-efficacy in bystander CPR. Multivariable logistic regression analysis was performed. The final model with an interaction term was evaluated to compare the effects of CPR training across different age and gender groups. Of 62425 eligible respondents who have had CPR training, 20213 (32.4%) had Practical-CPR-Training. Adjusted odds ratios (AORs) for self-efficacy were 4.08 (3.78-4.41) in Practical-CPR-Training, 2.61 (2.50-2.73) in male, 1.26 (1.16-1.36) in good self-rated health, 1.19 (1.10-1.29) in high school graduate, 1.19 (1.01-1.39) in persons living with stroke patients in household, and 1.17 (1.10-1.24) in Recent-CPR-Training. In interaction models, Practical-CPR-Training showed higher self-efficacy in all age and gender groups, whereas Recent-CPR-Training was not associated with better self-efficacy in elderly group, male (AOR, 0.90 [0.69-1.18]) and female (AOR, 0.94 [0.72-1.23]). Self-efficacy in bystander CPR was higher in person with recent CPR training with hands-on practice with a manikin. Copyright © 2015 Elsevier Inc. All rights reserved.

  1. Hemostatic resuscitation is neither hemostatic nor resuscitative in trauma hemorrhage.

    Trauma hemorrhage continues to carry a high mortality rate despite changes in modern practice. Traditional approaches to the massively bleeding patient have been shown to result in persistent coagulopathy, bleeding, and poor outcomes. Hemostatic (or damage control) resuscitation developed from the discovery of acute traumatic coagulopathy and increased recognition of the negative consequences of dilutional coagulopathy. These strategies concentrate on early delivery of coagulation therapy combined with permissive hypotension. The efficacy of hemostatic resuscitation in correcting coagulopathy and restoring tissue perfusion during acute hemorrhage has not been studied. This is a prospective cohort study of ROTEM and lactate measurements taken from trauma patients recruited to the multicenter Activation of Coagulation and Inflammation in Trauma (ACIT) study. A blood sample is taken on arrival and during the acute bleeding phase after administration of every 4 U of packed red blood cells (PRBCs), up to 12 U. The quantity of blood products administered within each interval is recorded. Of the 106 study patients receiving at least 4 U of PRBC, 27 received 8 U to 11 U of PRBC and 31 received more than 12 U of PRBC. Average admission lactate was 6.2 mEq/L. Patients with high lactate (≥5 mEq/L) on admission did not clear lactate until hemorrhage control was achieved, and no further PRBC units were required. On admission, 43% of the patients were coagulopathic (clot amplitude at 5 minutes ≤ 35 mm). This increased to 49% by PRBC 4; 62% by PRBC 8 and 68% at PRBC 12. The average fresh frozen plasma/PRBC ratio between intervals was 0.5 for 0 U to 4 U of PRBC, 0.9 for 5 U to 8 U of PRBC, 0.7 for 9 U to 12 U of PRBC. There was no improvement in any ROTEM parameter during ongoing bleeding. While hemostatic resuscitation offers several advantages over historical strategies, it still does not achieve correction of hypoperfusion or coagulopathy during the acute phase of trauma

    Effective training is needed for high-quality performance of staff nurses, who are often the first responders in initiating resuscitation. There is insufficient evidence to identify specific educational strategies that improve outcomes, including early recognition and rescue of the critical patient. This study was conducted to identify perceived competence and educational needs as well as to examine factors influencing perceived competence in resuscitation among staff nurses to build a resuscitation training curriculum. A convenience sample of 502 staff nurses was recruited from 11 hospitals in a single city. Staff nurses were asked to complete a self-administered questionnaire. On a five-point scale, chest compression was the lowest-rated technical skill (M = 3.33, SD = 0.80), whereas staying calm and focusing on required tasks was the lowest-rated non-technical skill (M = 3.30, SD = 0.80). Work duration, the usefulness of simulation, recent code experience, and recent simulation-based training were significant factors in perceived competence, F(4, 496) = 45.94, p < .001. Simulation-based resuscitation training was the most preferred training modality, and cardiac arrest was the most preferred training topic. Based on this needs assessment, a simulation-based resuscitation training curriculum with cardiac arrest scenarios is suggested to improve the resuscitation skills of staff nurses.

  5. Management of foetal asphyxia by intrauterine foetal resuscitation

    Velayudhareddy, S.; Kirankumar, H

    2010-01-01

    Management of foetal distress is a subject of gynaecological interest, but an anaesthesiologist should know about resuscitation, because he should be able to treat the patient, whenever he is directly involved in managing the parturient patient during labour analgesia and before an emergency operative delivery. Progressive asphyxia is known as foetal distress; the foetus does not breathe directly from the atmosphere, but depends on maternal circulation for its oxygen requirement. The oxygen delivery to the foetus depends on the placental (maternal side), placental transfer and foetal circulation. Oxygen transport to the foetus is reduced physiologically during uterine contractions in labour. Significant impairment of oxygen transport to the foetus, either temporary or permanent may cause foetal distress, resulting in progressive hypoxia and acidosis. Intrauterine foetal resuscitation comprises of applying measures to a mother in active labour, with the intention of improving oxygen delivery to the distressed foetus to the base line, if the placenta is functioning normally. These measures include left lateral recumbent position, high flow oxygen administration, tocolysis to reduce uterine contractions, rapid intravenous fluid administration, vasopressors for correction of maternal hypotension and amnioinfusion for improving uterine blood flow. Intrauterine Foetal Resuscitation measures are easy to perform and do not require extensive resources, but the results are encouraging in improving the foetal well-being. The anaesthesiologist plays a major role in the application of intrauterine foetal resuscitation measures. PMID:21189876

    2014-07-01

    Full Text Available Introduction: The objective of our study was to estimate the incidence of prescribing medication errors specifically made by a trainee and identify factors associated with these errors during the simulated resuscitation of a critically ill child. Methods: The results of the simulated resuscitation are described. We analyzed data from the simulated resuscitation for the occurrence of a prescribing medication error. We compared univariate analysis of each variable to medication error rate and performed a separate multiple logistic regression analysis on the significant univariate variables to assess the association between the selected variables. Results: We reviewed 49 simulated resuscitations . The final medication error rate for the simulation was 26.5% (95% CI 13.7% - 39.3%. On univariate analysis, statistically significant findings for decreased prescribing medication error rates included senior residents in charge, presence of a pharmacist, sleeping greater than 8 hours prior to the simulation, and a visual analog scale score showing more confidence in caring for critically ill children. Multiple logistic regression analysis using the above significant variables showed only the presence of a pharmacist to remain significantly associated with decreased medication error, odds ratio of 0.09 (95% CI 0.01 - 0.64. Conclusion: Our results indicate that the presence of a clinical pharmacist during the resuscitation of a critically ill child reduces the medication errors made by resident physician trainees.

    INTRODUCTION Simplifying the learning of cardiopulmonary resuscitation (CPR) is advocated to improve skill acquisition and retention. A simplified CPR training programme focusing on continuous chest compression, with a simple landmark tracing technique, was introduced to laypeople. The study aimed to examine the effectiveness of the simplified CPR training in improving lay rescuers’ CPR performance as compared to standard CPR. METHODS A total of 85 laypeople (aged 21–60 years) were recruited and randomly assigned to undertake either a two-hour simplified or standard CPR training session. They were tested two months after the training on a simulated cardiac arrest scenario. Participants’ performance on the sequence of CPR steps was observed and evaluated using a validated CPR algorithm checklist. The quality of chest compression and ventilation was assessed from the recording manikins. RESULTS The simplified CPR group performed significantly better on the CPR algorithm when compared to the standard CPR group (p CPR. However, a significantly higher number of compressions and proportion of adequate compressions was demonstrated by the simplified group than the standard group (p CPR group than in the standard CPR group (p CPR by focusing on continuous chest compressions, with simple hand placement for chest compression, could lead to better acquisition and retention of CPR algorithms, and better quality of chest compressions than standard CPR.

    Full Text Available Abstract Background Children with severe malnutrition who develop shock have a high mortality. Contrary to contemporaneous paediatric practice, current guidelines recommend use of low dose hypotonic fluid resuscitation (half-strength Darrows/5% dextrose (HSD/5D. We evaluated the safety and efficacy of this guideline compared to resuscitation with a standard isotonic solution. Methods A Phase II randomised controlled, safety and efficacy trial in Kenyan children aged over 6 months with severe malnutrition and shock including children with severe dehydration/shock and presumptive septic shock (non-diarrhoeal shock. Eligible children were randomised to HSD/5D or Ringer's Lactate (RL. A maximum of two boluses of 15 ml/kg of HSD/5D were given over two hours (as recommended by guidelines while those randomised to RL received 10 ml/kg aliquots half hourly (maximum 40 ml/kg. Primary endpoint was resolution of shock at 8 and 24 hours. Secondary outcomes included resolution of acidosis, adverse events and mortality. Results 61 children were enrolled: 41 had shock and severe dehydrating diarrhoea, 20 had presumptive septic shock; 69% had decompensated shock. By 8 hours response to volume resuscitation was poor with shock persisting in most children:-HSD/5D 15/22 (68% and RL14/25 (52%, p = 0.39. Oliguria was more prevalent at 8 hours in the HSD/5D group, 9/22 (41%, compared to RL-3/25 (12%, p = 0.02. Mortality was high, HSD/5D-15/26(58% and RL 13/29(45%; p = 0.42. Most deaths occurred within 48 hours of admission. Neither pulmonary oedema nor cardiogenic failure was detected. Conclusions Outcome was universally poor characterised by persistence of shock, oliguria and high case fatality. Isotonic fluid was associated with modest improvement in shock and survival when compared to HSD/5D but inconclusive due to the limitations of design and effectiveness of either resuscitation strategy. Although isotonic fluid resuscitation did not result in cardiogenic heart

    The ideas of collaboration and formation of scientific societies and registries for cardiac arrest were developed in the 18th century. The European Resuscitation Council (ERC) was formed in 1990. Nowadays, the ERC network consists of 30 National Resuscitation Councils (NRCs), which have an obligation to ensure that effective resuscitation services are provided and to promote education, training, and research in all aspects of resuscitation science. The central role of NRCs in decreasing the incidence of cardiac arrest may be highlighted and enhanced by the incorporation and implementation of the following suggestions. NRCs should emphasize and actively participate in acute care training of healthcare professionals and of lay rescuers. Implementation of current resuscitation guidelines should be a priority of each NRC and identification of the weakest link in the chain of survival should be a priority.

    Pediatric resuscitation has been a topic of discussion for years. It is difficult to keep abreast of changing recommendations, especially for busy pediatricians who do not regularly use these skills. This review will focus on the most recent guidelines for resuscitation drugs. Three specific questions will be discussed: standard dose versus high-dose epinephrine, amiodarone use, and the future of vasopressin in pediatric resuscitation. The issue of using high-dose epinephrine for cardiopulmonary resuscitation refractory to standard dose epinephrine has been a topic of debate for many years. Recently, a prospective, double-blinded study was performed to help settle the debate. These results will be reviewed and compared with previous studies. Amiodarone is a medication that was added to the pediatric resuscitation algorithms with the most recent recommendations from the American Heart Association in 2000. Its use and safety will also be discussed. Another topic that is resurfacing in resuscitation is the use of vasopressin. Its mechanism and comparisons to other agents will be highlighted, although its use in the pediatric patient has not been thoroughly studied. Pediatric resuscitation is a constantly evolving subject that is on the mind of anyone taking care of sick children. Clinicians are continually searching for the most effective methods to resuscitate children in terms of short- and long-term outcomes. It is important to be familiar with not only the agents being used but also the optimal way to use them.

    Aortic occlusion is a potentially valuable tool for early resuscitation in patients nearing extremis or in arrest from severe hemorrhage. The American Association for the Surgery of Trauma's Aortic Occlusion in Resuscitation for Trauma and Acute Care Surgery registry identified trauma patients without penetrating thoracic injury undergoing aortic occlusion at the level of the descending thoracic aorta (resuscitative thoracotomy [RT] or zone 1 resuscitative endovascular balloon occlusion of the aorta [REBOA]) in the emergency department (ED). Survival outcomes relative to the timing of CPR need and admission hemodynamic status were examined. Two hundred and eighty-five patients were included: 81.8% were males, with injury due to penetrating mechanisms in 41.4%; median age was 35.0 years (interquartile range 29 years) and median Injury Severity Score was 34.0 (interquartile range 18). Resuscitative thoracotomy was used in 71%, and zone 1 REBOA in 29%. Overall survival beyond the ED was 50% (RT 44%, REBOA 63%; p = 0.004) and survival to discharge was 5% (RT 2.5%, REBOA 9.6%; p = 0.023). Discharge Glasgow Coma Scale score was 15 in 85% of survivors. Prehospital CPR was required in 60% of patients with a survival beyond the ED of 37% and survival to discharge of 3% (all p > 0.05). Patients who did not require any CPR before had a survival beyond the ED of 70% (RT 48%, REBOA 93%; p American College of Surgeons. Published by Elsevier Inc. All rights reserved.

    An analysis is presented of delivery room (DR) neonatal resuscitation practices in Spanish hospitals. A questionnaire was sent by e-mail to all hospitals attending deliveries in Spain. A total of 180 questionnaires were sent, of which 155 were fully completed (86%). Less than half (71, 46%) were level i or ii hospitals, while 84 were level iii hospital (54%). In almost three-quarters (74.2%) of the centres, parents and medical staff were involved in the decision on whether to start resuscitation or withdraw it. A qualified resuscitation team (at least two members) was available in 80% of the participant centres (63.9% level i-ii, and 94.0% level iii, PNeonatal resuscitation courses were held in 90.3% of the centres. The availability of gas blenders, pulse oximeters, manual ventilators, and plastic wraps was higher in level iii hospitals. Plastic wraps for pre-term hypothermia prevention were used in 63.9% of the centres (40.8% level i-iiand 83.3% level iii, PCPAP in preterm infants was applied in 91.7% of the tertiary hospitals. In last 5 years some practices have improved, such neonatal resuscitation training, pulse oximeter use, or early CPAP support. There is an improvement in some practices of neonatal resuscitation. Significant differences have been found as regards the equipment or practices in the DR, when comparing hospitals of different levels of care. Copyright © 2015 Asociación Española de Pediatría.

    Acute trauma coagulopathy (ATC) is seen in 30% to 40% of severely injured casualties. Early use of blood products attenuates ATC, but the timing for optimal effect is unknown. Emergent clinical practice has started prehospital deployment of blood products (combined packed red blood cells and fresh frozen plasma [PRBCs:FFP], and alternatively PRBCs alone), but this is associated with significant logistical burden and some clinical risk. It is therefore imperative to establish whether prehospital use of blood products is likely to confer benefit. This study compared the potential impact of prehospital resuscitation with (PRBCs:FFP 1:1 ratio) versus PRBCs alone versus 0.9% saline (standard of care) in a model of severe injury. Twenty-four terminally anesthetised Large White pigs received controlled soft tissue injury and controlled hemorrhage (35% blood volume) followed by a 30-min shock phase. The animals were allocated randomly to one of three treatment groups during a 60-min prehospital evacuation phase: hypotensive resuscitation (target systolic arterial pressure 80 mmHg) using either 0.9% saline (group 1, n = 9), PRBCs:FFP (group 2, n = 9), or PRBCs alone (group 3, n = 6). Following this phase, an in-hospital phase involving resuscitation to a normotensive target (110 mmHg systolic arterial blood pressure) using PRBCs:FFP was performed in all groups. There was no mortality in any group. A coagulopathy developed in group 1 (significant increase in clot initiation and dynamics shown by TEG [thromboelastography] R and K times) that persisted for 60 to 90 min into the in-hospital phase. The coagulopathy was significantly attenuated in groups 2 and 3 (P = 0.025 R time and P = 0.035 K time), which were not significantly different from each other. Finally, the volumes of resuscitation fluid required was significantly greater in group 1 compared with groups 2 and 3 (P = 0.0067) (2.8 ± 0.3 vs. 1.9 ± 0.2 and 1.8 ± 0.3 L, respectively). This difference was principally

    The purpose of this multicentre clinical randomized controlled blinded prospective trial was to determine whether an inspiratory impedance threshold device (ITD), when used in combination with active compression-decompression (ACD) cardiopulmonary resuscitation (CPR), would improve survival rates in patients with out-of-hospital cardiac arrest. Patients were randomized to receive either a sham (n = 200) or an active impedance threshold device (n = 200) during advanced cardiac life support performed with active compression-decompression cardiopulmonary resuscitation. The primary endpoint of this study was 24 h survival. The 24 h survival rates were 44/200 (22%) with the sham valve and 64/200 (32%) with the active valve (P = 0.02). The number of patients who had a return of spontaneous circulation (ROSC), intensive care unit (ICU) admission, and hospital discharge rates was 77 (39%), 57 (29%), and 8 (4%) in the sham valve group versus 96 (48%) (P = 0.05), 79 (40%) (P = 0.02), and 10 (5%) (P = 0.6) in the active valve group. Six out of ten survivors in the active valve group and 1/8 survivors in the sham group had normal neurological function at hospital discharge (P = 0.1). The use of an impedance valve in patients receiving active compression-decompression cardiopulmonary resuscitation for out-of-hospital cardiac arrest significantly improved 24 h survival rates.

    To compare the incidence of ventilator-associated pneumonia (VAP) with or without isotonic saline instillation before tracheal suctioning. As a secondary objective, we compared the incidence of endotracheal tube occlusion and atelectasis. Randomized clinical trial. The study was conducted in a medical surgical intensive care unit of an oncologic hospital. We selected consecutive patients needing mechanical ventilation for >72 hrs. Patients were allocated into two groups: a saline group that received instillation of 8 mL of saline before tracheal suctioning and a control group which did not. VAP was diagnosed based on clinical suspicion and confirmed by bronchoalveolar lavage quantitative culture. The incidence of atelectasis on daily chest radiography and endotracheal tube occlusions were recorded. The sample size was calculated to a power of 80% and a type I error probability of 5%. One hundred thirty patients were assigned to the saline group and 132 to the control group. The baseline demographic variables were similar between groups. The rate of clinically suspected VAP was similar in both groups. The incidence of microbiological proven VAP was significantly lower in the saline group (23.5% x 10.8%; p = 0.008) (incidence density/1.000 days of ventilation 21.22 x 9.62; p < 0.01). Using the Kaplan-Meier curve analysis, the proportion of patients remaining without VAP was higher in the saline group (p = 0.02, log-rank test). The relative risk reduction of VAP in the saline instillation group was 54% (95% confidence interval, 18%-74%) and the number needed to treat was eight (95% confidence interval, 5-27). The incidence of atelectases and endotracheal tube occlusion were similar between groups. Instillation of isotonic saline before tracheal suctioning decreases the incidence of microbiological proven VAP.

    We present the case of a 57 year old patient patient who underwent a diagnostic coronariography that showed three-vessel coronary disease. He presented cardiorespiratory arrest immediately at the end of the procedure; basic and advanced resuscitation maneuvers were started during a two hours period. During the resuscitation, primary angioplasty and stent implantation in the circumflex artery was performed. The patient recovered spontaneous circulation and was transferred to the coronary care unit. On the second day, a successful myocardial revascularization was performed and was discharged 16 days after the event without evident neurological deficit.

    To evaluate the efficacy of high (≥1:2) and low (ratio resuscitation in patients with severe trauma requiring massive blood transfusion. The databases including the Cochrane Library, Pubmed, Web of Science, and EMBASE were systemically searched for relevant studies published between January, 2009 and April, 2016. The selection of studies, assessment of methodological quality and data extraction were performed by two researchers independently according to the inclusion and exclusion criteria. The main endpoint was 24-h mortality, 30-day mortality and 24-h survival rate. Five observational studies reporting outcomes of 1024 patients were included in this meta-analysis. Four studies documented civilian cases and one study had a military setting. No significant differences were found in the Injury Severity Score (ISS) between patient groups receiving high and low plasma: RBC ratio resuscitation. Compared with the low-ratio group, the patients with high-ratio resuscitation showed a significant reduction in the 24-h mortality rate (OR=0.35, 95%CI [0.25, 0.48], Pratio resuscitation within the initial 24 h following the trauma (HR=2.34, 95%CI [1.46, 3.73], P=0.00001). Raising the plasma: RBC ratio to 0.5 or higher may decrease the mortality rate of the patients with severe trauma who need massive blood transfusion.

    This study aimed to explore the molecular mechanism of the protective effects of hydrogen-saturated saline on NIHL. Guinea pigs were divided into three groups: hydrogen-saturated saline; normal saline; and control. For saline administration, the guinea pigs were given daily abdominal injections 3 d before and 1 h before noise exposure. ABR were tested to examine cochlear physiology changes. The changes of 8-hydroxy-desoxyguanosine (8-HOdG), interleukin-1 (IL-1), interleukin-6 (IL-6), interleukin-10 (IL-10), tumor necrosis factor-α (TNF-α), intercellular cell adhesion molecule-1 (ICAM-1) and high mobility group box-1 protein (HMGB1) in the cochlea were also examined. The results showed that pre-treatment with hydrogen-saturated saline could significantly attenuate noise-induced hearing loss. The concentration of 8-HOdG was also significantly decreased in the hydrogen-saturated saline group compared with the normal saline group. After noise exposure, the concentrations of IL-1, IL-6, TNF-α, and ICAM-1 in the cochlea of guinea pigs in the hydrogen-saturated saline group were dramatically reduced compared to those in the normal saline group. The concentrations of HMGB-1 and IL-10 in the hydrogen-saturated saline group were significantly higher than in those in the normal saline group immediately and at 7 d after noise exposure. This study revealed for the first time the protective effects of hydrogen-saturated saline on noise-induced hearing loss (NIHL) are related to both the anti-oxidative activity and anti-inflammatory activity.

    Our study objectives were to explore moral distress among pediatric team clinicians within the context of resuscitation experiences, and determine whether there were any distinctively ethical perspectives on moral distress that could be conceptualized as challenges to professional integrity, rather than to previously described psychological responses of clinicians. Descriptive, exploratory qualitative study. A large tertiary pediatric academic hospital in Houston, TX. Twenty-five PICU resuscitation team clinicians were interviewed from December 2012 to April 2013. None. All clinicians reported experiencing moral distress during certain resuscitations. Twenty-one of 25 clinicians reflected and acknowledged that their sense of professional integrity had been challenged during those resuscitation events. Four main components of resuscitation experience that induced moral distress were identified: 1) experiences where there was lack of understanding of the big picture; 2) experiences where there was suboptimal team leadership; 3) experiences where there was variable meanings to the word "resuscitation"; and 4) experiences were there was uncertainty of role responsibility. The perception of moral distress exists among pediatric clinicians during resuscitations and could be conceptualized as challenges to professional integrity. This ethical framework offers an alternative approach to understanding and investigating the complex layers of moral distress.

    The new European Resuscitation Council (ERC) guidelines for cardiopulmonary resuscitation (CPR) published on October 18th, 2010, replace those published in 2005 and are based on the latest International Consensus on CPR Science with Treatment Recommendations (CoSTR). For both adult and pediatric resuscitation, the most important general changes include: the introduction of chest compression-only CPR in primary cardiac arrest as an option for rescuers who are unable or unwilling to perform expired-air ventilation; increased emphasis on uninterrupted, good-quality CPR and minimisation of both pre- and post-shock pauses during defibrillation. For adult resuscitation, the recommended chest compression depth and rate are 5-6 cm and 100-120 compressions per minute, respectively. Both a specific period of CPR before defibrillation during out-of-hospital resuscitation and use of endotracheal route for drug delivery during advanced life support are no longer recommended. During postresuscitation care, inspired oxygen should be titrated to obtain an arterial oxygen saturation of 94-98%, to avoid possible damage from hyperoxemia. In pediatric resuscitation, the role of pulse palpation for the diagnosis of cardiac arrest has been de-emphasised. The compression-to-ventilation ratio depends on the number of rescuers available, and a 30:2 ratio is acceptable even for rescuers with a duty to respond if they are alone. Chest compression depth should be at least 1/3 of the anterior-posterior chest diameter. The use of automated external defibrillators for children under one year of age should be considered.

    in prevalence of core themes by role. Rank data for the 25 statements were converted to a point system (5 points for most important, 4 points for second most important, etc), and a mixed within-between analysis of variance was used to determine the association of role and relative rank. There were 125 respondents (62% response rate) who provided 893 coded statements. The core theme of communication-in particular, closed-loop communication-was the most prevalent theme, although no differences in the proportion of themes represented were seen by PED staff of different roles (P = 0.18). There was a significant effect from the core theme (P = 0.002, partial η = 0.13), with highest priority on team leader performance (mean points out of 5 = 2.5 ± 1.9), but neither effect nor interaction with role (P = 0.6, P = 0.7). When answering open-ended questions regarding barriers to effective resuscitations, all disciplines perceived communication, particularly closed-loop communication, as the primary theme lacking during resuscitations. However, when choosing from a list of themes, all groups except physicians perceived deficiencies in team leader qualities to be the greatest barrier. We as physicians must work on improving our communication and leadership attributes if we want to improve the quality of our resuscitations.

    2016-06-01

    Cardiopulmonary resuscitation (CPR) represents the cornerstone of cardiac arrest resuscitation care. Prompt delivery of high-quality CPR can dramatically improve survival outcomes; however, the definitions of optimal CPR have evolved over several decades. The present review will discuss the metrics of CPR delivery, and the evidence supporting the importance of CPR quality to improve clinical outcomes. The introduction of new technologies to quantify metrics of CPR delivery has yielded important insights into CPR quality. Investigations using CPR recording devices have allowed the assessment of specific CPR performance parameters and their relative importance regarding return of spontaneous circulation and survival to hospital discharge. Additional work has suggested new opportunities to measure physiologic markers during CPR and potentially tailor CPR delivery to patient requirements. Through recent laboratory and clinical investigations, a more evidence-based definition of high-quality CPR continues to emerge. Exciting opportunities now exist to study quantitative metrics of CPR and potentially guide resuscitation care in a goal-directed fashion. Concepts of high-quality CPR have also informed new approaches to training and quality improvement efforts for cardiac arrest care.

    Brain injury after neonatal cardiopulmonary resuscitation in the term baby is often described as an all-or-nothing phenomenon, but little is known about possible late cognitive consequences. The aim of this study was therefore to investigate whether children who needed cardiopulmonary resuscitation because of presumed mild and moderate intra-partum asphyxia with no evidence of neurological impairments at 18 mo of age may display neuropsychological impairments later in life. A long-term follow-up of young adults was carried out. A blinded comprehensive neuropsychological assessment of the main aspects of cognitive functions was made. The subjects who were resuscitated were divided into two groups according to the clinical course: 20 cases with mild asphyxia and 11 cases with moderate asphyxia, all followed prospectively and compared with 18 healthy controls. The 31 subjects were born at term or near-term and selected randomly from 59 infants born in 1969-1978 at Sahlgren's Hospital, Göteborg. All infants with early neurological impairments were excluded. No major differences could be established between the two clinical groups and normal controls in any aspects of cognitive function or intelligence. All the groups performed within the normal range in all tests. A tendency toward minor deficits in verbal ability in the mild group compared to the controls was found. Only one subject had a clear, defined memory deficit. Infants who underwent cardiopulmonary resuscitatation at birth without neurological deficits at 18 mo of age did not show any cognitive deficits or neuropsychological impairments in adulthood even though inferior performance on some verbal subtests was observed compared to the control group.

    Optimal patterns for fluid management are controversial in the resuscitation of major trauma. Similarly, appropriate surgical timing is often unclear in orthopedic polytrauma. Early appropriate care (EAC) has recently been introduced as an objective model to determine readiness for surgery based on the resuscitation of metabolic acidosis. EAC is an objective treatment algorithm that recommends fracture fixation within 36 h when either lactate acidosis using EAC. At an adult level 1 trauma center, 332 patients with major trauma (Injury Severity Score (ISS) ≥16) were prospectively treated with EAC. The time from injury to EAC resuscitation was determined in all patients. Age, race, gender, ISS, American Society of Anesthesiologists score (ASA), body mass index (BMI), outside hospital transfer status, number of fractures, and the specific fractures were also reviewed. Complications in the 6-month post-operative period were adjudicated by an independent multidisciplinary committee of trauma physicians and included infection, sepsis, pulmonary embolism, deep venous thrombosis, renal failure, multiorgan failure, pneumonia, and acute respiratory distress syndrome. Univariate analysis and binomial logistic regression analysis were used to compare complications between groups. Sixty-six patients developed complications, which was less than a historical cohort of 1,441 patients (19.9% vs. 22.1%). ISS (p acidosis was associated with a higher complication rate. Identifying the innate differences in the response, regulation, and resolution of acidosis in these critically injured patients is an important area for trauma research. Level 1: prognostic study.

    To evaluate efficacy and safety of delivery room (DR) sustained lung inflation (SLI) in resuscitation of preterm neonates. Randomized Controlled Trial including 112 preterm infants randomized to either SLI (n = 57) using T-piece resuscitator [maximum three inflations with maximum pressure of 30 cmH 2 O for 15 s followed by continuous positive airway pressure (CPAP) of 5-7 cmH 2 O] or conventional bag/mask inflation (CBMI) (n = 55) using traditional self-inflating bag (maximum pressure of 40 cmH 2 O at a rate of 40-60 per min). Failure was defined as the need for DR or first 72 h intubation. Cord and 2-h post-resuscitation blood samples were collected to measure interleukin (IL)-1β and tumor necrosis factor-α levels before and after intervention. SLI was associated with significantly higher success rate compared to CBMI [75.4 versus 54.5%; p = 0.017], lower need for DR intubation [5.3% versus 23.6%; (X 2  =   7.7; p = 0.005)], higher 5-min-Apgar score (median 8 versus 7; p = 0.018), shorter duration on nasal-CPAP (p = 0.017), and non-significantly different air leak (7% versus 11%; p = 0.3) and bronchopulmonary dysplasia rates among survivors (2% versus 11%; p = 0.09). Post-resuscitation IL-1β plasma levels increased significantly in CBMI (p = 0.009) and not in SLI group. Delivery room SLI is more effective than intermittent bag and mask inflation for improving short-term respiratory outcome in preterm infants, without significant adverse effects.

    Emergency physicians must be masters of the airway. The patient with tracheostomy can present with complications, and because of anatomy, airway and resuscitation measures can present several unique challenges. Understanding tracheostomy basics, features, and complications will assist in the emergency medicine management of these patients. The aim of this review is to provide an overview of the basics and features of the tracheostomy, along with an approach to managing tracheostomy complications. This review provides background on the reasons for tracheostomy placement, basics of tracheostomy, and tracheostomy tube features. Emergency physicians will be faced with complications from these airway devices, including tracheostomy obstruction, decannulation or tube dislodgement, stenosis, tracheoinnominate fistula, and tracheoesophageal fistula. Critical patients should be evaluated in the resuscitation bay, and consultation with ENT should be completed while the patient is in the department. This review provides several algorithms for management of complications. Understanding these complications and an approach to airway management during cardiac arrest resuscitation is essential to optimizing patient care. Tracheostomy patients can present unique challenges for emergency physicians. Knowledge of the basics and features of tracheostomy tubes can assist physicians in managing life-threatening complications including tube obstruction, decannulation, bleeding, stenosis, and fistula.

    BACKGROUND: To assess the effectiveness of the telephone chest-compression-only cardiopulmonary resuscitation (CPR) guided by a pre-recorded instructional audio when compared with dispatcher-assisted resuscitation. METHODS: It was a prospective, blind, randomised controlled study involving 109 medical students without previous CPR training. In a standardized mannequin scenario, after the step of dispatcher-assisted cardiac arrest recognition, the participants performed compression-only resuscitation guided over the telephone by either: (1) the pre-recorded instructional audio (n=57); or (2) verbal dispatcher assistance (n=52). The simulation video records were reviewed to assess the CPR performance using a 13-item checklist. The interval from call reception to the first compression, total number and rate of compressions, total number and duration of pauses after the first compression were also recorded. RESULTS: There were no significant differences between the recording-assisted and dispatcher-assisted groups based on the overall performance score (5.6±2.2 vs. 5.1±1.9, P>0.05) or individual criteria of the CPR performance checklist. The recording-assisted group demonstrated significantly shorter time interval from call receipt to the first compression (86.0±14.3 vs. 91.2±14.2 s, PCPR. Future studies are warranted to further assess feasibility of using instructional audio aid as a potential alternative to dispatcher assistance.

    To observe the effects of mesenteric lymph drainage on the metabolism of red blood cell (RBC) in hemorrhagic shock (HS) rats following fluid resuscitation. Eighteen male Wistar rats were randomly divided into sham group (n=6), HS group (n=6), HS + drainage group (n=6). After 1.5 hours of HS model prepared, the animals were given fluid resuscitation by lost blood plus equal volume of Ringer solution within 30 minutes in HS and HS + drainage groups, and mesenteric lymph drainage was performed after 1 hour of hypotension in HS + drainage group. At 3 hours after resuscitation or corresponding time, blood samples were obtained from abdominal aorta. Membrane suspensions of RBC prepared from part of whole blood samples were used to measure the activities of adenosine triphosphate ase (ATPase) and contents of ATP and lactic acid (LA), the intracellular fluid of RBC prepared from part of whole blood samples was used to determine the concentration of 2,3-diphosphoglyceric acid (2,3-DPG), Na(+) and K(+), plasma samples isolated from blood by centrifugation were used to determine the concentration of Na(+), K(+), Cl(-) and total Ca. Compared with sham group, the content of ATP (μmol/g), activity of Na(+)-K(+)-ATPase (μmol×mg(-1)×h(-1)) and Ca(2+)-ATPase (μmol×mg(-1)×h(-1)) in RBC membrane and total Ca (mmol/L) in plasma were decreased markedly (ATP: 6.698±0.938 vs. 10.670±1.466, Na(+)-K(+)-ATPase: 0.042±0.010 vs. 0.066±0.019, Ca(2+)-ATPase: 0.054±0.015 vs. 0.081±0.017, total Ca: 2.27±0.18 vs. 2.66±0.21, P0.05). Compared with HS group, the contents of 2,3-DPG (4.459±0.900) and ATP (8.859±1.189), the activities of Na(+)-K(+)-ATPase (0.089±0.022), Ca(2+)-ATPase (0.082±0.020) of RBC were increased in HS + drainage group, and the level of LA (2.060±0.810) was decreased observably (Pdrainage plays an important role in improving the metabolism of RBC in HS rats following fluid resuscitation, subsequently, may preserve the structure and function of RBC.

    Cardiopulmonary resuscitation training is an essential element of clinical skill development for healthcare providers. The International Liaison Committee on Resuscitation has described issues related to cardiopulmonary resuscitation and emergency cardiovascular care education. Educational interventions have been initiated to try to address these issues using a team-based approach and simulation technologies that offer a controlled, safe learning environment. The aim of the study is to review and synthesize published studies that address the primary question "What are the features and effectiveness of educational interventions related to simulation-enhanced, team-based cardiopulmonary resuscitation training?" We conducted a systematic review focused on educational interventions pertaining to cardiac arrest and emergencies that addressed this main question. The findings are presented together with a discussion of the effectiveness of various educational interventions. In conclusion, student attitudes toward interprofessional learning and simulation experiences were more positive. Research reports emphasized the importance of adherence to established guidelines, adopting a holistic approach to training, and that preliminary training, briefing, deliberate practices, and debriefing should help to overcome deficiencies in cardiopulmonary resuscitation training.

    We retrospectively assessed the brain computed tomographic (CT) findings in 22 post-cardiopulmonary resuscitation (CPR) patients excluding neonatal cases. On the basis of the CT findings, the patients were divided into two groups. Eight patients (36.4 %) had bilateral abnormal lowdensity areas in the basal ganglia (Group I). The remaining 14 patients (63.6 %) had no abnormalities in that area (Group II). In Group I, the incidence of primary cardiac arrest and duration of advanced life support (ALS) was significantly different (p < 0.05) from Group II. Sex, age, duration of basic life support (BLS), time elapsed from initiation of BLS to initial CT and from initiation of ALS to initial CT was not significantly different between the two groups. Outcome was very poor in both groups and no significant difference was noted between them. We conclude that primary cardiac arrest and long duration of ALS were predictors of abnormal bilateral low-density areas in the basal ganglia in post-CPR patients. However, their appearance was not related to outcome. (author)

    This study was done to compare 2 techniques of pulse oximeter sensor application during neonatal resuscitation for faster signal detection. Sensor to infant first (STIF) and then to oximeter was compared with sensor to oximeter first (STOF) and then to infant in ≥28 weeks gestations. The primary outcome was time from completion of sensor application to reliable signal, defined as stable display of heart rate and saturation. Time from birth to sensor application, time taken for sensor application, time from birth to reliable signal, and need to reapply sensor were secondary outcomes. An intention-to-treat analysis was done, and subgroup analysis was done for gestation and need for resuscitation. One hundred fifty neonates were randomized with 75 to each technique. The median (IQR) time from sensor application to detection of reliable signal was longer in STIF group compared with STOF group (16 [15-17] vs. 10 [6-18] seconds; P signal did not differ between the 2 methods (STIF: 61 [52-76] seconds; STOF: 58 [47-73] seconds [P = .09]). Time taken for signal acquisition was longer with STIF than with STOF in both subgroups. In the delivery room setting, the STOF method recognized saturation and heart rate faster than the STIF method. The time from birth to reliable signal was similar with the 2 methods.

    Background Although international newborn resuscitation guidance has been in force for some time, there are no UK data on current newborn resuscitation practices. Objective Establish delivery room (DR) resuscitation practices in the UK, and identify any differences between neonatal intensive care units (NICU), and other local neonatal services. Methods We conducted a structured two-stage survey of DR management, among UK neonatal units during 2009–2010 (n = 192). Differences between NICU services (tertiary level) and other local neonatal services (non-tertiary) were analysed using Fisher's exact and Student's t-tests. Results There was an 89% response rate (n = 171). More tertiary NICUs institute DR CPAP than non-tertiary units (43% vs. 16%, P = 0.0001) though there was no significant difference in frequency of elective intubation and surfactant administration for preterm babies. More tertiary units commence DR resuscitation in air (62% vs. 29%, P < 0.0001) and fewer in 100% oxygen (11% vs. 41%, P < 0.0001). Resuscitation of preterm babies in particular, commences with air in 56% of tertiary units. Significantly more tertiary units use DR pulse oximeters (58% vs. 29%, P < 0.01) and titrate oxygen based on saturations. Almost all services use occlusive wrapping to maintain temperature for preterm infants. Conclusions In the UK, there are many areas of good evidence based DR practice. However, there is marked variation in management, including between units of different designation, suggesting a need to review practice to fulfil new resuscitation guidance, which will have training and resource implications.

    Although clinical and pharmacologic guidelines exist for the practice of cardiopulmonary resuscitation in children (Pediatric Advanced Life Support), the practice of extracorporeal cardiopulmonary resuscitation in pediatric cardiac patients remains without universally accepted standards. We aim to explore variation in extracorporeal cardiopulmonary resuscitation procedures by surveying clinicians who care for this high-risk patient population. A 28-item cross-sectional survey was distributed via a web-based platform to clinicians focusing on cardiopulmonary resuscitation practices and extracorporeal membrane oxygenation team dynamics immediately prior to extracorporeal membrane oxygenation cannulation. Pediatric hospitals providing extracorporeal mechanical support services to patients with congenital and/or acquired heart disease. Critical care/cardiology specialist physicians, cardiothoracic surgeons, advanced practice nurse practitioners, respiratory therapists, and extracorporeal membrane oxygenation specialists. None. Survey web links were distributed over a 2-month period with critical care and/or cardiology physicians comprising the majority of respondents (75%). Nearly all respondents practice at academic/teaching institutions (97%), 89% were from U.S./Canadian institutions and 56% reported less than 10 years of clinical experience. During extracorporeal cardiopulmonary resuscitation, a majority of respondents reported adherence to guideline recommendations for epinephrine bolus dosing (64%). Conversely, 19% reported using only one to three epinephrine bolus doses regardless of extracorporeal cardiopulmonary resuscitation duration. Inotropic support is held after extracorporeal membrane oxygenation cannulation "most of the time" by 58% of respondents and 94% report using afterload reducing/antihypertensive agents "some" to "most of the time" after achieving full extracorporeal membrane oxygenation support. Interruptions in chest compressions are common

    Mechanical ventilation via automated in-hospital ventilators is quite common during cardiopulmonary resuscitation. It is not known whether different inspiratory triggering sensitivity settings of ordinary ventilators have different effects on actual ventilation, gas exchange and hemodynamics during resuscitation. 18 pigs enrolled in this study were anaesthetized and intubated. Continuous chest compressions and mechanical ventilation (volume-controlled mode, 100% O2, respiratory rate 10/min, and tidal volumes 10ml/kg) were performed after 3 minutes of ventricular fibrillation. Group trig-4, trig-10 and trig-20 (six pigs each) were characterized by triggering sensitivities of 4, 10 and 20 (cmH2O for pressure-triggering and L/min for flow-triggering), respectively. Additionally, each pig in each group was mechanically ventilated using three types of inspiratory triggering (pressure-triggering, flow-triggering and turned-off triggering) of 5 minutes duration each, and each animal matched with one of six random assortments of the three different triggering settings. Blood gas samples, respiratory and hemodynamic parameters for each period were all collected and analyzed. In each group, significantly lower actual respiratory rate, minute ventilation volume, mean airway pressure, arterial pH, PaO2, and higher end-tidal carbon dioxide, aortic blood pressure, coronary perfusion pressure, PaCO2 and venous oxygen saturation were observed in the ventilation periods with a turned-off triggering setting compared to those with pressure- or flow- triggering (all PVentilation with pressure- or flow-triggering tends to induce hyperventilation and deteriorating gas exchange and hemodynamics during CPR. A turned-off patient triggering or a pressure-triggering of 20 cmH2O is preferred for ventilation when an ordinary inpatient hospital ventilator is used during resuscitation.

    Use of universally ABO-compatible group AB plasma for trauma resuscitation can be challenging due to supply limitations. Many centers are now using group A plasma during the initial resuscitation of traumatically injured patients. This study was undertaken to evaluate the impact of this practice on mortality and hospital length of stay (LOS). Seventeen trauma centers using group A plasma in trauma patients of unknown ABO group participated in this study. Eligible patients were group A, B, and AB trauma patients who received at least 1 unit of group A plasma. Data collected included patient sex, age, mechanism of injury, Trauma Injury Severity Score (TRISS) probability of survival, and number of blood products transfused. The main outcome of this study was in-hospital mortality differences between group B and AB patients compared to group A patients. Data on early mortality (≤24 hr) and hospital LOS were also collected. There were 354 B and AB patients and 809 A patients. The two study groups were comparable in terms of age, sex, TRISS probability of survival, and total number of blood products transfused. The use of group A plasma during the initial resuscitation of traumatically injured patients of unknown ABO group was not associated with increased in-hospital mortality, early mortality, or hospital LOS for group B and AB patients compared to group A patients. These results support the practice of issuing thawed group A plasma for the initial resuscitation of trauma patients of unknown ABO group. © 2017 AABB.

    A validated mathematical model of microvascular exchange in thermally injured humans has been used to predict the consequences of different forms of resuscitation and potential modes of action of pharmaceuticals on the distribution and transport of fluid and macromolecules in the body. Specially, for 10 and/or 50 per cent burn surface area injuries, predictions are presented for no resuscitation, resuscitation with the Parkland formula (a high fluid and low protein formulation) and resuscitation with the Evans formula (a low fluid and high protein formulation). As expected, Parkland formula resuscitation leads to interstitial accumulation of excess fluid, while use of the Evans formula leads to interstitial accumulation of excessive amounts of proteins. The hypothetical effects of pharmaceuticals on the transport barrier properties of the microvascular barrier and on the highly negative tissue pressure generated postburn in the injured tissue were also investigated. Simulations predict a relatively greater amelioration of the acute postburn edema through modulation of the postburn tissue pressure effects.

    This study aims to investigate the protective effects and underlying mechanisms of hydrogen-rich saline on the cognitive functions of elder mice with partial hepatectomy-induced postoperative cognitive dysfunction (POCD). Ninety-six old male Kunming mice were randomly divided into 4 groups (n = 24 each): control group (group C), hydrogen-rich saline group (group H), POCD group (group P), and POCD + hydrogen-rich saline group (group PH). Cognitive function was subsequently assessed using Morris water-maze (MWM) test. TNF-α and IL-1β levels were measured by enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry, along with NF-κB activity determined by ELISA. The morphology of hippocampal tissues were further observed by HE staining. Learning and memory abilities of mice were significantly impaired at day 10 and day 14 post-surgery, as partial hepatectomy significantly prolonged the escape latency, decreased time at the original platform quadrant and frequency of crossing in group P when compared to group C (p hydrogen-rich saline (group PH) partially rescued spatial memory and learning as it shortened escape latency and increased time and crossing frequency of original platform compared to group P (p hydrogen-rich saline. Hydrogen-rich saline can alleviate POCD via inhibiting NF-κB activity in the hippocampus and reducing inflammatory response.

    'Massive' transfusion is a poorly defined inclusion criteria for studies examining the blood and blood product that are used during trauma resuscitation. We aimed to compare the traditional definition of massive transfusion (≥10 units in 24 h) to a more acute definition of at least 5 units in 4 h. Multitrauma patients were subgrouped according to the traditional definition and compared with the acute definition. Demographics, presenting vital signs and blood results, management including transfusion practice and outcomes were retrospectively studied. Associations of transfused fresh frozen plasma:packed red blood cells (PRBC) ratios with mortality were studied. There were 927 patients who received PRBCs in the first 24 h, with 314 patients identified using the traditional definition and 303 patients using the acute definition. The patients identified using the traditional definition received 18 (12-29) units of PRBC in 24 h, significantly higher than those identified using the acute definition [15 (9-29) units, Pdefinition excluded a significant proportion of patients who died in the emergency department. By using the acute definition to select a study sample, there seems to be an increase in mortality with fresh frozen plasma:PRBC ratio of 1 : 1 ratio compared with a 1 : 2 ratio. The traditional 'massive' transfusion definition not only 'dilutes' the potential study samples with a less acute group of patients, but also further excludes patients who die early. This latter group is most likely to be benefitted from any change to resuscitation practice. An acute definition of massive transfusion should be adopted when examining clinical practice during initial trauma resuscitation.

    Family Presence During Resuscitation (FPDR), although not a new concept, remains inconsistently implemented by emergency personnel. Many larger metropolitan emergency departments (ED) have instigated a care coordinator role, however these personnel are often from a non-nursing background and have therefore limited knowledge about the clinical aspects of the resuscitation. In rural emergency departments there are simply not enough staff to allocate an independent role. A separate care coordinator role, who is assigned to care for the family and not take part in the resuscitation has been well documented as essential to the successful implementation of FPDR. One rural and one metropolitan emergency department in the state of Victoria, Australia were observed and data was collected on FPDR events. The participants consisted of resuscitation team members, including; emergency trained nurses, senior medical officers, general nurses and doctors. The participants were not told that the data would be recorded around interactions with family members or team discussions regarding family involvement in the resuscitation, following ethical approval involving limited disclosure of the aims of the study. Seventeen adult presentations (Metro n=9, Rural n=8) were included in this study and will be presented as resuscitation case studies. The key themes identified included ambiguity around resuscitation status, keeping the family informed, family isolation and inter-professional communication. During 17 adult resuscitation cases, staff were witnessed communicating with family, which was often limited and isolation resulted. Family were often uninformed or separated from their family member, however when a family liaison person was available it was found to be beneficial. This research indicated that staff could benefit from a designated family liaison role, formal policy and further education. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Our aim was to investigate cerebral and cardiac tissue injury subsequent to use of vasopressin and adrenaline in combination compared with vasopressin alone during cardiopulmonary resuscitation (CPR). In a randomized, prospective, laboratory animal study 28 anesthetized piglets were subject to a 12-min untreated cardiac arrest and subsequent CPR. After 1 min of CPR, 10 of the piglets received 0.4 U/kg of arg(8)-vasopressin (V group), and 10 piglets received 0.4 U/kg of arg(8)-vasopressin, 1 min later followed by 20 µg/kg body weight of adrenaline, and another 1 min later continuous administration (10 µg/kg/min) of adrenaline (VA group). After 8 min of CPR, the piglets were defibrillated and monitored for another 3 h. Then they were killed and the brain immediately removed pending histological analysis. During CPR, the VA group had higher mean blood pressure and cerebral cortical blood flow (CCBF) but similar coronary perfusion pressure. After restoration of spontaneous circulation there was no difference in the pressure variables, but CCBF tended to be (36% ± 16%) higher in the V group. Neuronal injury and signs of a disrupted blood-brain barrier (BBB) were greater, 20% ± 4% and 21% ± 4%, respectively, in the VA group. In a background study of repeated single doses of adrenaline every third minute after 5 min arrest but otherwise the same protocol, histological measurements showed even worse neural injury and disruption of the BBB. Combined use of vasopressin and adrenaline caused greater signs of cerebral and cardiac injury than use of vasopressin alone during experimental cardiopulmonary resuscitation.

    Damage control resuscitation and early thoracotomy have been used to increase survival after severe injury in combat. There has been a renewed interest in resuscitative endovascular balloon occlusion of the aorta (REBOA) in both civilian and military medical practices. REBOA may result in visceral and limb ischaemia that could be harmful if use of REBOA is premature or prolonged. The purpose of this paper is to align our experience of combat injuries with the known capability of REBOA to suggest an implementation strategy for the use of REBOA in combat care. It may replace the resuscitative effect of thoracotomy; can provide haemostasis of non-compressible torso injuries such as the junctional and pelvic haemorrhage caused by improvised explosive devices. However, prehospital use of REBOA must be in the context of an overall surgical plan and should be restricted to deployment in the distal aorta. Although REBOA is technically easier than a thoracotomy, it requires operator training and skill to add to the beneficial effect of damage control resuscitation and surgery. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    The aim of this study was to determine the influence of perceived authority on pediatric resuscitation teams' response to an incorrect order given by a medical superior. As part of a larger multicenter prospective interventional study, interprofessional pediatric resuscitation teams (n = 48) participated in a video-recorded simulated resuscitation scenario with an infant in unstable, refractory supraventricular tachycardia. A confederate actor playing a senior physician entered the scenario partway through and ordered the incorrect dose and delivery method of the antiarrhythmic, procainamide. Video recordings were analyzed with a modified Advocacy Inquiry Scale, assessing the teams' ability to challenge the incorrect order, and a novel confederate hierarchical demeanor rating. The association between Advocacy Inquiry score and hierarchical demeanor rating, and whether or not the confederate's incorrect order was followed were determined. Fifty percent (n = 24) of resuscitation teams followed the confederate's incorrect order. The teams' ability to challenge the incorrect order (P authority figure. Institution-based factors may impact this rate of incorrect medication administration.

    Through necessity, military medicine has been the driver of medical innovation throughout history. The battlefield presents challenges, such as the requirement to provide care while under threat, resource limitation, and prolonged evacuation times, which must be overcome to improve casualty survival. Focus must also be placed on identifying the causes, and timing, of death within the battlefield. By doing so, military medical doctrine can be shaped, appropriate goals set, new concepts adopted, and relevant technologies investigated and implemented. The majority of battlefield casualties still die in the prehospital environment, before reaching a medical treatment facility, and hemorrhage remains the leading cause of potentially survivable death. Many countries have adopted policies that push damage control resuscitation forward into the prehospital setting, while understanding the need for timely medical evacuation. Although these policies vary according to country, the majority share many common principles. These include the need for early catastrophic hemorrhage control at point-of-wounding, judicious use of fluid resuscitation, use of blood products as far forward as possible, and early evacuation to a surgical facility. Some countries place medical providers with the ability, and resources, for advanced resuscitation with the forward fighting units (perhaps at company level), whereas others have established en route resuscitation capabilities. If we are to continue to improve battlefield casualty survival, we must continue to work together and learn from each other. We must also carry on working alongside our civilian colleagues so that the benefits of translational experience are not lost. This review describes several countries current military approaches to prehospital trauma care. These approaches, refined through a decade of experience, merit consideration for integration into civilian prehospital care practice.

    Mass cardiopulmonary resuscitation (CPR) 99 in Singapore was a large-scale multi-organisational effort to increase awareness and impart basic cardiac life support skills to the lay public. Mass CPR demonstrations followed by small group manikin practice with instructor guidance was conducted simultaneously in three centres, four times a day. The exercise enlisted 15 community organisations and received the support of 19 other organisations. Three hundred and ninety-eight manikins and 500 instructors ('I's) were mobilised to teach an audience of 6000 participants ('P's). Two surveys, for 'I's and 'P's were conducted with respondent rates of 65.8% and 50%, respectively. 73.6% of the P-respondents ('P-R's) indicated that they attended the event to increase their knowledge. 66.9% were willing to attend a more comprehensive CPR course. Concerns and perceptions in performing bystander CPR were assessed.

    The resuscitation of children from cardiac arrest and shock remains a challenging goal. The pharmacologic principles underlying current recommendations for intervention in pediatric cardiac arrest have been reviewed. Current research efforts, points of controversy, and accepted practices that may not be most efficacious have been described. Epinephrine remains the most effective resuscitation adjunct. High-dose epinephrine is tolerated better in children than in adults, but its efficacy has not received full analysis. The preponderance of data continues to point toward the ineffectiveness and possible deleterious effects of overzealous sodium bicarbonate use. Calcium chloride is useful in the treatment of ionized hypocalcemia but may harm cells that have experienced asphyxial damage. Atropine is an effective agent for alleviating bradycardia induced by increased vagal tone, but because most bradycardia in children is caused by hypoxia, improved oxygenation is the intervention of choice. Adenosine is an effective and generally well-tolerated agent for the treatment of supraventricular tachycardia. Lidocaine is the drug of choice for ventricular dysrhythmias, and bretylium, still relatively unexplored, is in reserve. Many pediatricians use dopamine for shock in the postresuscitative period, but epinephrine is superior. Most animal research on cardiac arrest is based on models with ventricular fibrillation that probably are not reflective of cardiac arrest situations most often seen in pediatrics.

    Full Text Available This review, written on the occasion of the 70th anniversary of the Institute for General Reanimatology of the Russian Academy of Medical Sciences, provides an update of recent research in the field of resuscitation medicine carried out at the Safar Center for Resuscitation Research at the University of Pittsburgh School of Medicine. Current and recent studies describing bench to bedside investigation in the areas of traumatic brain injury (TBI, cardiopulmonary arrest, hemorrhagic shock, and ultra-novel approaches to resuscitation are discussed. Investigation in TBI across a variety of topics by many investigators including mechanism of neuronal death, oxidative and nitrative stress, proteomics, adenosine, serotonin, novel magnetic resonance imaging application, inflicted childhood neurotrauma, and TBI rehabilitation is addressed. Research discussed in the program of cardiopulmonary arrest includes optimization of the use of mild hypothermia and novel investigation in experimental asphyxial cardiac arrest. In the program on hemorrhagic shock, our recent work on the application of mild hypothermia to prolong the «golden hour» is presented. Finally, a brief overview of our studies of a novel approach to the resuscitation of exsan-guination cardiac arrest using emergency preservation for resuscitation (EPR is provided.

    Trauma-related hypotension and coagulopathy worsen secondary brain injury in patients with traumatic brain injuries (TBIs). Early damage control resuscitation with blood products may mitigate hypotension and coagulopathy. Preliminary data suggest resuscitation with plasma in large animals improves neurologic function after TBI; however, data in humans are lacking. We retrospectively identified all patients with multiple injuries age >15 years with head injuries undergoing prehospital resuscitation with blood products at a single Level I trauma center from January 2002 to December 2013. Inclusion criteria were prehospital resuscitation with either packed red blood cells (pRBCs) or thawed plasma as sole colloid resuscitation. Patients who died in hospital and those using anticoagulants were excluded. Primary outcomes were Glasgow Outcomes Score Extended (GOSE) and Disability Rating Score (DRS) at dismissal and during follow-up. Of 76 patients meeting inclusion criteria, 53% (n = 40) received prehospital pRBCs and 47% (n = 36) received thawed plasma. Age, gender, injury severity or TBI severity, arrival laboratory values, and number of prehospital units were similar (all p > 0.05). Patients who received thawed plasma had an improved neurologic outcome compared to those receiving pRBCs (median GOSE 7 [7-8] vs. 5.5 [3-7], p plasma had improved functionality compared to pRBCs (median DRS 2 [1-3.5] vs. 9 [3-13], p plasma compared to pRBCs by both median GOSE (8 [7-8] vs. 6 [6-7], p plasma is associated with improved neurologic and functional outcomes at discharge and during follow-up compared to pRBCs alone. These preliminary data support the further investigation and use of plasma in the resuscitation of critically injured TBI patients. Therapeutic, level V.

    Within Australian hospitals, cardiac and respiratory arrests result in a resuscitation attempt unless the patient is documented as not for resuscitation. To examine the consistency of policies and documentation for withholding in-hospital resuscitation across health services. An observational, qualitative review of hospital policy and documentation was conducted in June 2013 in three public and two private sector hospitals in metropolitan Melbourne. Not for resuscitation (NFR) forms were evaluated for physical characteristics, content, authorisation and decision-making. Hospital policies were coded for alerts, definition of futility and burden of treatment and management of discussions and dissent. There was a lack of standardisation, with each site using its own unique NFR form and accompanying site-specific policies. Differences were found in who could authorise the decision, what was included on the form, the role of patients and families, and how discussions were managed and dissent resolved. Futility and burden of treatment were not defined independently. These inconsistencies across sites contribute to a lack of clarity regarding the decision to withhold resuscitation, and have implications for staff employed across multiple hospitals. NFR forms should be reviewed and standardised so as to be clear, uniform and consistent with the legislative framework. We propose a two-stage process of documentation. Stage 1 facilitates discussion of patient-specific goals of care and consideration of limitations of treatment. Stage 2 serves to communicate a NFR order. Decisions to withhold resuscitation are inherently complex but could be aided by separating the decision-making process from the communication of the decision, resulting in improved end-of-life care. © 2014 The Authors; Internal Medicine Journal © 2014 Royal Australasian College of Physicians.

    Conclusion: The Veress needle, usually used for insufflating the abdomen during laparoscopy, can also be an effective tool to decompress the abdomen when presented with tension pneumoperitoneum. Abdominal visceral injuries are rare following CPR but do occur and will likely require an invasive intervention. Surviving cardiac arrest as a young person and living without deficits outweighs the risk of a surgical correction for a visceral injury. While resuscitation measures are critical for survival, medical personnel need to be aware of potential complications from resuscitative efforts and potential management strategies.

    Full Text Available Background: The survival rate of out-of-hospital cardiac arrest (OHCA victims in Lebanon is low. A national policy on resuscitation practice is lacking. This survey explored the practices of emergency physicians related to the resuscitation of OHCA victims in Lebanon. Methods: A sample of 705 physicians working in emergency departments (EDs was recruited and surveyed using the LimeSurvey software (Carsten Schmitz, Germany. Seventy-five participants responded, yielding 10.64% response rate. Results: The most important factors in the participants' decision to initiate or continue resuscitation were presence of pulse on arrival (93.2%, underlying cardiac rhythm (93.1%, the physician's ethical duty to resuscitate (93.2%, transport time to the ED (89%, and down time (84.9%. The participants were optimistic regarding the survival of OHCA victims (58.1% reporting > 10% survival and reported frequent resuscitation attempts in medically futile situations. The most frequently reported challenges during resuscitation decisions were related to pressure or presence of victim's family (38.8% and lack of policy (30%. Conclusion: In our setting, physicians often rely on well-established criteria for initiating/continuing resuscitation; however, their decisions are also influenced by cultural factors such as victim's family wishes. The findings support the need for a national policy on resuscitation of OHCA victims.

    High-quality cardiopulmonary resuscitation (CPR) by laypersons is a key determinant of both outcome and survival for out-of-hospital cardiac arrest. Dispatcher-assisted CPR (telephone-CPR, T-CPR) increases the frequency and correctness of bystander-CPR but results in prolonged time to first chest compressions. However, it remains unclear whether instructions for rescue ventilation and/or chest compressions should be recommended for dispatcher-assisted CPR. The aim of this study was to evaluate both principles of T-CPR with respect to CPR quality. Randomised controlled single-blinded manikin trial. University Hospital of Cologne, Germany, 1 July 2012 to 30 September 2012. Sixty laypersons between 18 and 65 years. Medically educated individuals, medical professionals and pregnant women were excluded. Participants were asked to resuscitate a manikin and were randomised into three groups: not dispatcher-assisted (uninstructed) CPR (group 1; U-CPR; n = 20), dispatcher-assisted compression-only CPR (group 2; DACO-CPR; n = 19) and full dispatcher-assisted CPR with rescue ventilation (group 3; DAF-CPR; n = 19). Specific parameters of CPR quality [i.e. no-flow-time (NFT) as well as compression and ventilation parameters] were analysed. To compare different groups we used Student's t test and P less than 0.05 was considered significant. Initial NFT was lowest in the DACO-CPR group (mean 21.3 ± 14.4%), followed by dispatcher-assisted full CPR (mean 49.1 ± 8.5%) and by unassisted CPR (mean 55.0 ± 12.9%). Initial NFT covering the time of instruction was lower in DACO-CPR (12.1 ± 5.4%) as compared to dispatcher-assisted full CPR (20.7 ± 8.1%). Compression depth was similar in all three groups: 40.6 ± 13.0 mm (unassisted CPR), 41.0 ± 12.2 mm (DACO-CPR) and 38.8 ± 15.8 mm (dispatcher-assisted full CPR). Average compression frequency was highest in the DACO-CPR group (65.2 ± 22.4 min) compared with the unassisted CPR

    Survival from out-of-hospital cardiac arrest is increased by bystander cardiopulmonary resuscitation (CPR). Bystander performance can be improved when CPR instructions are delivered by a calltaker at the Emergency Communications Centre. Little is known about a young person's ability to understand these instructions and perform CPR correctly. We assessed the ability of a group of untrained young people to effectively apply these directions to an adult resuscitation manikin. 87 youngsters aged 7-15 years with no previous training in CPR were separately equipped with a mobile phone and an adult assessment manikin. They phoned the emergency number (111) and were automatically diverted to a senior emergency medical dispatcher (EMD). The EMD delivered resuscitation instructions which complied fully with Medical Priority Dispatch System (version 12.1). Performance was monitored using a Laerdal Computerised Skill Reporting System. Average compression depth increased with age from 10.3 mm to 30 mm for 8 and 15 year olds respectively. 100 compressions per minute was achieved in youngsters aged 10 years and older but the rate fatigued over time and improved after interruption for two ventilations. Those aged 11 years and older consistently compressed the chest from 31 mm to 50mm. Only one participant could successfully ventilate the manikin by mouth-to-mouth. This study demonstrates that untrained youngsters should perform compression-only CPR. From 11 years of age, they can effectively perform dispatcher-directed CPR by compressing the chest at an appropriate rate and depth. However, their technique benefits from formal training.

    The T-piece resuscitator (TPR) has seen increased use as a primary resuscitation device with newborns. Traditional TPR design uses a high resistance expiratory valve to produce positive end expiratory pressure (PEEP) or continuous positive airway pressure (CPAP) at resuscitation. A new TPR device that uses a dual flow ratio valve (fluidic flip) to produce PEEP/CPAP is now available (rPAP). We aimed to compare the measured ventilation performance of different TPR devices in a controlled bench test study. Single operator provided positive pressure ventilation to an incremental testlung compliance (Crs) model (0.5-5 mL/cmH 2 O) with five different brands of TPR device (Atom, Neopuff, rPAP, GE Panda warmer and Draeger Resuscitaire). At recommended peak inflation pressure (PIP) 20 cmH 2 O, PEEP of 5 cmH 2 O and rate of 60 inflations per minute. 1864 inflations were analysed. Four of the five devices tested demonstrated inadvertent elevations in mean PEEP (5.5-10.3 cmH 2 O, p<0.001) from set value as Crs was increased, while one device (rPAP) remained at the set value. Measured PIP exceeded the set value in two infant warmer devices (GE and Draeger) with inbuilt TPR at Crs of 0.5 (24.5 and 23.5 cmH 2 O, p<0.001). Significant differences were seen in tidal volumes across devices particularly at higher Crs (p<0.001). Results show important variation in delivered ventilation from set values due to inherent TPR device design characteristics with a range of lung compliances expected at birth. Device-generated inadvertent PEEP and overdelivery of PIP may be clinically deleterious for term and preterm newborns or infants with larger Crs during resuscitation. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    2005-08-01

    This paper reports a literature review examining factors that enhance retention of knowledge and skills during and after resuscitation training, in order to identify educational strategies that will optimize survival for victims of cardiopulmonary arrest. Poor knowledge and skill retention following cardiopulmonary resuscitation training for nursing and medical staff has been documented over the past 20 years. Cardiopulmonary resuscitation training is mandatory for nursing staff and is important as nurses often discover the victims of in-hospital cardiac arrest. Many different methods of improving this retention have been devised and evaluated. However, the content and style of this training lack standardization. A literature review was undertaken using the Cumulative Index to Nursing and Allied Health Literature, MEDLINE and British Nursing Index databases and the keywords 'cardiopulmonary resuscitation', 'basic life support', 'advanced life support' and 'training'. Papers published between 1992 and 2002 were obtained and their reference lists scrutinized to identify secondary references, of these the ones published within the same 10-year period were also included. Those published in the English language that identified strategies to enhance the acquisition or retention of Cardiopulmonary resuscitation skills and knowledge were included in the review. One hundred and five primary and 157 secondary references were identified. Of these, 24 met the criteria and were included in the final literature sample. Four studies were found pertaining to cardiac arrest simulation, three to peer tuition, four to video self-instruction, three to the use of different resuscitation guidelines, three to computer-based learning programmes, two to voice-activated manikins, two to automated external defibrillators, one to self-instruction, one to gaming and the one to the use of action cards. Resuscitation training should be based on in-hospital scenarios and current evidence

    Objective Successful resuscitation from cardiac arrest requires the delivery of high-quality chest compressions, encompassing parameters such as adequate rate, depth, and full recoil between compressions. The lack of compression recoil (“leaning” or “incomplete recoil”) has been shown to adversely affect hemodynamics in experimental arrest models, but the prevalence of leaning during actual resuscitation is poorly understood. We hypothesized that leaning varies across resuscitation events, possibly due to rescuer and/or patient characteristics and may worsen over time from rescuer fatigue during continuous chest compressions. Methods This was an observational clinical cohort study at one academic medical center. Data were collected from adult in-hospital and Emergency Department arrest events using monitor/defibrillators that record chest compression characteristics and provide real-time feedback. Results We analyzed 112,569 chest compressions from 108 arrest episodes from 5/2007 to 2/2009. Leaning was present in 98/108 (91%) cases; 12% of all compressions exhibited leaning. Leaning varied widely across cases: 41/108 (38%) of arrest episodes exhibited 20% compression leaning. When evaluating blocks of continuous compressions (>120 sec), only 4/33 (12%) had an increase in leaning over time and 29/33 (88%) showed a decrease (presuscitation care and exhibited a wide distribution, with most leaning within a subset of resuscitations. Leaning decreased over time during continuous chest compression blocks, suggesting that either leaning may not be a function of rescuer fatiguing, or that it may have been mitigated by automated feedback provided during resuscitation episodes.

    An epidural injection of saline was reported to extend spinal anesthesia because of a volume effect. The aim of this study was to evaluate the influence of the baricity of spinal local anesthetics upon the extension of spinal anesthesia by epidural injection of saline. Forty patients undergoing elective lower-limb surgery were randomly allocated to four groups of 10 patients each. Group A received no epidural injection after the spinal administration of hyperbaric tetracaine (dissolved in 10% glucose). Group B received an epidural injection of 8 ml of physiological saline 20 min after spinal hyperbaric tetracaine. Group C received no epidural injection after spinal isobaric tetracaine (dissolved in physiological saline). Group D received an epidural injection of 8 ml of saline 20 min after spinal isobaric tetracaine. The level of analgesia was examined by the pinprick method at 5-min intervals. The levels of analgesia 20 min after spinal anesthesia were significantly higher in hyperbaric groups than in isobaric groups [T5 (T2-L2) vs. T7 (T3-12)]. After epidural injection of saline, the levels of analgesia in groups B and D were significantly higher than in groups A and C. The segmental increases after epidural saline injection were 2 (0-3) in group B and 2 (1-7) in group D. Sensation in the sacral area remained 20 min after spinal block in one patient in group D; however, it disappeared after epidural saline injection. In this study, 8 ml of epidural saline extended spinal analgesia. However, there was no difference between the augmenting effect in isobaric and hyperbaric spinal anesthesia. We conclude that the reinforcement of spinal anesthesia by epidural injection of saline is not affected by the baricity of the spinal anesthetic solution used.

    Early intervention can dramatically alter outcome in foals. Cardio-pulmonary cerebral resuscitation can be successful and clinically worthwhile when applied to foals that arrest as part of the birthing process. Readily available equipment and an ordered plan starting with addressing the respiratory system (airway and breathing) followed by the circulatory system (circulation and drugs) are the keys to success. Hypoglycemia is common in foals that are not nursing and in septic foals. Support of serum glucose can be an important emergency treatment. Respiratory support with oxygen therapy should be considered in all foals following resuscitation and dystocia. Other foals that are likely to benefit from oxygen are those that are dyspneic, cyanotic, meconium-stained after birth,or recumbent. Emergency therapies, applied correctly, are expected to result in decreased mortality and morbidity.

  17. Laryngeal mask airway versus bag-mask ventilation or endotracheal intubation for neonatal resuscitation.

    Qureshi, Mosarrat J; Kumar, Manoj

    2018-03-15

    Providing effective positive pressure ventilation is considered to be the single most important component of successful neonatal resuscitation. Ventilation is frequently initiated manually with bag and face mask (BMV) followed by endotracheal intubation if respiratory depression continues. These techniques may be difficult to perform successfully resulting in prolonged resuscitation or neonatal asphyxia. The laryngeal mask airway (LMA) may achieve initial ventilation and successful resuscitation faster than a bag-mask device or endotracheal intubation. Among newborns requiring positive pressure ventilation for cardio-pulmonary resuscitation, is LMA more effective than BMV or endotracheal intubation for successful resuscitation? When BMV is either insufficient or ineffective, is effective positive pressure ventilation and successful resuscitation achieved faster with the LMA compared to endotracheal intubation? We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL 2017, Issue 1), MEDLINE via PubMed (1966 to 15 February 2017), Embase (1980 to 15 February 2017), and CINAHL (1982 to 15 February 2017). We also searched clinical trials registers, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials. We included randomised and quasi-randomised controlled trials that compared LMA for neonatal resuscitation with either BMV or endotracheal intubation and reported on any outcomes related to neonatal resuscitation specified in this review. Two review authors independently evaluated studies for risk of bias assessments, and extracted data using Cochrane Neonatal criteria. Categorical treatment effects were described as relative risks and continuous treatment effects were described as the mean difference, with 95% confidence intervals (95% CI) of estimates. We included seven trials that involved a total of 794 infants. Five

    Full Text Available Objective: To identify literature evidences related to actions to promote family's presence during cardiopulmonary resuscitation and invasive procedures in children hospitalized in pediatric and neonatal critical care units. Data sources : Integrative literature review in PubMed, SciELO and Lilacs databases, from 2002 to 2012, with the following inclusion criteria: research article in Medicine, or Nursing, published in Portuguese, English or Spanish, using the keywords "family", "invasive procedures", "cardiopulmonary resuscitation", "health staff", and "Pediatrics". Articles that did not refer to the presence of the family in cardiopulmonary resuscitation and invasive procedures were excluded. Therefore, 15 articles were analyzed. Data synthesis : Most articles were published in the United States (80%, in Medicine and Nursing (46%, and were surveys (72% with healthcare team members (67% as participants. From the critical analysis, four themes related to the actions to promote family's presence in invasive procedures and cardiopulmonary resuscitation were obtained: a to develop a sensitizing program for healthcare team; b to educate the healthcare team to include the family in these circumstances; c to develop a written institutional policy; d to ensure the attendance of family's needs. Conclusions: Researches on these issues must be encouraged in order to help healthcare team to modify their practice, implementing the principles of the Patient and Family Centered Care model, especially during critical episodes.

    Full Text Available BackgroundWhile delayed umbilical cord clamping in preterm infants has shown to improve long-term neurological outcomes, infants who are thought to need resuscitation do not receive delayed cord clamping even though they may benefit the most. A mobile resuscitation platform allows infants to be resuscitated at the mother’s bedside with the cord intact. The newborn is supplied with placental blood during the resuscitation in view of the mother. The objective of the study is to assess the usability and acceptability of mobile resuscitation platform, LifeStart trolley, among the infants’ parents and perinatal providers.MethodsA resuscitation platform was present during every delivery that required advanced neonatal providers for high-risk deliveries. Perinatal providers and parents of the infants were given a questionnaire shortly after the delivery.Results60 neonatal subjects were placed on the trolley. The majority of deliveries were high risk for meconium-stained amniotic fluid (43%, and non-reassuring fetal heart rate (45%. About 50% of neonatal providers felt that there were some concerns regarding access to the baby. No parents were uncomfortable with the bedside neonatal interventions, and most parents perceived that communication was improved because of the proximity to the care team.ConclusionBedside resuscitation with umbilical cord intact through the use of a mobile resuscitation trolley is feasible, safe, and effective, but about half of the perinatal providers expressed concerns. Logistical issues such as improved space management and/or delivery setup should be considered in centers planning to perform neonatal resuscitation with an intact cord.

Regular 'Community Meetings', skill development training courses and Farmer Field Schools are being arranged for these groups. Printed material in Urdu and English on new technologies is also being published regularly for the benefit of project farmers, extension workers and other interested persons, elsewhere. Visible improvements in the project area with time clearly indicate that the Saline Agriculture Farmer Participatory Development Project in Pakistan is an elegant model to demonstrate how science can help in effecting change in life of millions of farmers in a few years, if their full participation is ensured.

    Prehospital termination of resuscitation (TOR) rules have not been widely validated outside of Western countries. This study evaluated the performance of TOR rules in an Asian metropolitan with a mixed-tier emergency medical service (EMS). We analysed the Utstein registry of adult, non-traumatic out-of-hospital cardiac arrests (OHCAs) in Taipei to test the performance of TOR rules for advanced life support (ALS) or basic life support (BLS) providers. ALS and BLS-TOR rules were tested in OHCAs among three subgroups: (1) resuscitated by ALS, (2) by BLS and (3) by mixed ALS and BLS. Outcome definition was in-hospital death. Sensitivity, specificity, positive predictive value (PPV), negative predictive value and decreased transport rate (DTR) among various provider combinations were calculated. Of the 3489 OHCAs included, 240 were resuscitated by ALS, 1727 by BLS and 1522 by ALS and BLS. Overall survival to hospital discharge was 197 patients (5.6%). Specificity and PPV of ALS-TOR and BLS-TOR for identifying death ranged from 70.7% to 81.8% and 95.1% to 98.1%, respectively. Applying the TOR rules would have a DTR of 34.2-63.9%. BLS rules had better predictive accuracy and DTR than ALS rules among all subgroups. Application of the ALS and BLS TOR rules would have decreased OHCA transported to the hospital, and BLS rules are reasonable as the universal criteria in a mixed-tier EMS. However, 1.9-4.9% of those who survived would be misclassified as non-survivors, raising concern of compromising patient safety for the implementation of the rules.

    It has been generally accepted that enhanced blood flow during closed-chest CPR is generated from compression of the heart between the sternum and the spine. To visualize the heart during closed-chest massage, we performed two-dimensional echocardiography (2DE) during resuscitation efforts in four patients who had cardiac arrest. 2DE analysis showed that (1) the LV internal dimensions did not change appreciably with chest compression; (2) the mitral and aortic valves were open simultaneously during the compression phase; (3) blood flow into the right heart, as evidenced by saline bubble contrast, occurred during the relaxation phase; and (4) compression of the right ventricle and LA occurred in varying amounts in all patients. We conclude that stroke volume from the heart during CPR does not result from compression of the LV. Rather, CPR-induced improved cardiocirculatory dynamics appear to be principally the result of changes in intrathoracic pressure created by sternal compression.

    Although trauma-hemorrhage produces tissue hypoxia, systemic inflammatory response and organ dysfunction, the mechanisms responsible for these alterations are not clear. Using a potent selective inducible nitric oxide (NO) synthase inhibitor, N-[3-(aminomethyl) benzyl]acetamidine (1400W), and a nonselective NO synthase inhibitor, N(G)-nitro-L-arginine methyl ester (L-NAME), we investigated whether inducible NO synthase plays any role in producing hepatic injury, inflammation, and changes of protein expression following trauma-hemorrhage. To investigate this, male Sprague-Dawley rats were subjected to midline laparotomy and hemorrhagic shock (mean blood pressure 35-40 mmHg for approximately 90 min) followed by fluid resuscitation. Animals were treated with either vehicle (DMSO) or 1400W (10 mg/kg body wt ip), or L-NAME (30 mg/kg iv), 30 min before resuscitation and killed 2 h after resuscitation. Trauma-hemorrhage/resuscitation induced a marked hypotension and increase in markers of hepatic injury (i.e., plasma alpha-glutathione S-transferase, tissue myeloperoxidase activity, and nitrotyrosine formation). Hepatic expression of iNOS, hypoxia-inducible factor-1alpha, ICAM-1, IL-6, TNF-alpha, and neutrophil chemoattractant (cytokine-induced neutrophil chemoattractant-1 and macrophage inflammatory protein-2) protein levels were also markedly increased following trauma-hemorrhage/resuscitation. Administration of the iNOS inhibitor 1400W significantly attenuated hypotension and expression of these mediators of hepatic injury induced by trauma-hemorrhage/resuscitation. However, administration of L-NAME could not attenuate hepatic dysfunction and tissue injury mediated by trauma-hemorrhage, although it improved mean blood pressure as did 1400W. These results indicate that increased expression of iNOS following trauma-hemorrhage plays an important role in the induction of hepatic damage under such conditions.

    The European Resuscitation Council (ERC) guidelines changed in 2005. We investigated the impact of these changes on no flow time and on the quality of cardiopulmonary resuscitation (CPR). Simulated cardiac arrest (CA) scenarios were managed randomly in manikins using ERC 2000 or 2005 guidelines. Pairs of paramedics/paramedic students treated 34 scenarios with 10min of continuous ventricular fibrillation. The rhythm was analysed and defibrillation shocks were delivered with a semi-automatic defibrillator, and breathing was assisted with a bag-valve-mask; no intravenous medication was given. Time factors related to human intervention and time factors related to device, rhythm analysis, charging and defibrillation were analysed for their contribution to no flow time (time without chest compression). Chest compression quality was also analysed. No flow time (mean+/-S.D.) was 66+/-3% of CA time with ERC 2000 and 32+/-4% with ERC 2005 guidelines (PERC 2000) versus 107+/-4s (ERC 2005) during 600-s scenarios (P=0.237). Device factor interventions took longer using ERC 2000 guidelines: 290+/-19s versus 92+/-15s (PERC 2005 guidelines (808+/-92s versus 458+/-90s, P<0.001), but the quality of CPR did not differ between the groups. The use of a single shock sequence with guidelines 2005 has decreased the no flow time during CPR when compared with guidelines 2000 with multiple shocks.

    Prompt hemorrhage control and adequate fluid resuscitation are the key components of early trauma care. However, the optimal resuscitation strategy remains controversial. In this context the small volume resuscitation (SVR) concept with hypertonic-hyperoncotic solutions is a new strategy. This was a retrospective study in the Helicopter Emergency Medical Service over a 5-year period. Included were all major trauma victims if they were candidates for SVR (initially 4 ml HyperHaes/kg body weight, followed by conventional fluid resuscitation with crystalloids and colloids). Demographic data, type and cause of injury and injury severity score (ISS) were recorded and the amount of fluid volume and the hemodynamic profile were analyzed. Negative side-effects as well as sodium chloride serum levels on hospital admission were recorded. A total of 342 trauma victims (male 70.2%, mean age 39.0 ± 18.8 years, ISS 31.6 ± 16.9, ISS>16, 81.6%) underwent prehospital SVR. A blunt trauma mechanism was predominant (96.8%) and the leading cause of injury was motor vehicle accidents (61.5%) and motorcycle accidents (22.3%). Multiple trauma and polytrauma were noted in 87.4% of the cases. Predominant was traumatic brain injury (73.1%) as well as chest injury (73.1%) followed by limb injury (69.9%) and abdominal/pelvic trauma (45.0%). Within the whole study group in addition to 250 ml HyperHaes, mean volumes of 1214 ± 679 ml lactated Ringers and 1288 ± 954 ml hydroxethylstarch were infused during the prehospital treatment phase. There were no statistically significant differences in the amount of crystalloids and colloids infused regarding the subgroups multisystem trauma (ISS>16), severe traumatic brain injury (GCS80 mmHg significantly less colloids (1035 ± 659 ml vs. 1288 ± 954 ml, pconcept of small volume resuscitation provides early and effective hemodynamic control. Clinical side-effects associated with bolus infusion of hypertonic-hyperoncotic solutions are rare.

    The authors aimed to evaluate the role of post-resuscitation electrocardiogram (ECG) in patients showing significant ST-segment changes on the initial ECG and to provide useful diagnostic indicators for physicians to determine in which out-of-hospital cardiac arrest (OHCA) patients brain computed tomography (CT) should be performed before emergency coronary angiography. The usefulness of immediate brain CT and ECG for all resuscitated patients with nontraumatic OHCA remains controversial. Between January 2010 and December 2014, 1,088 consecutive adult nontraumatic patients with return of spontaneous circulation who visited the emergency department of 3 tertiary care hospitals were enrolled. After excluding 245 patients with obvious extracardiac causes, 200 patients were finally included. The patients were categorized into 2 groups: those with ST-segment changes with spontaneous subarachnoid hemorrhage (SAH) (n = 50) and those with OHCA of suspected cardiac origin group (n = 150). The combination of 4 ECG characteristics including narrow QRS (<120 ms), atrial fibrillation, prolonged QTc interval (≥460 ms), and ≥4 ST-segment depressions had a 66.0% sensitivity, 80.0% specificity, 52.4% positive predictive value, and 87.6% negative predictive value for predicting SAH. The area under the receiver-operating characteristic curves in the post-resuscitation ECG findings was 0.816 for SAH. SAH was observed in a substantial number of OHCA survivors (25.0%) with significant ST-segment changes on post-resuscitation ECG. Resuscitated patients with narrow QRS complex and any 2 ECG findings of atrial fibrillation, QTc interval prolongation, or ≥4 ST-segment depressions may help identify patients who need brain CT as the next diagnostic work-up.

    End-tidal carbon dioxide (ETCO2) correlates with systemic blood flow and resuscitation rate during cardiopulmonary resuscitation (CPR) and may potentially direct chest compression performance. We compared ETCO2-directed chest compressions with chest compressions optimized to pediatric basic life support guidelines in an infant swine model to determine the effect on rate of return of spontaneous circulation (ROSC). Forty 2-kg piglets underwent general anesthesia, tracheostomy, placement of vascular catheters, ventricular fibrillation, and 90 seconds of no-flow before receiving 10 or 12 minutes of pediatric basic life support. In the optimized group, chest compressions were optimized by marker, video, and verbal feedback to obtain American Heart Association-recommended depth and rate. In the ETCO2-directed group, compression depth, rate, and hand position were modified to obtain a maximal ETCO2 without video or verbal feedback. After the interval of pediatric basic life support, external defibrillation and intravenous epinephrine were administered for another 10 minutes of CPR or until ROSC. Mean ETCO2 at 10 minutes of CPR was 22.7±7.8 mm Hg in the optimized group (n=20) and 28.5±7.0 mm Hg in the ETCO2-directed group (n=20; P=0.02). Despite higher ETCO2 and mean arterial pressure in the latter group, ROSC rates were similar: 13 of 20 (65%; optimized) and 14 of 20 (70%; ETCO2 directed). The best predictor of ROSC was systemic perfusion pressure. Defibrillation attempts, epinephrine doses required, and CPR-related injuries were similar between groups. The use of ETCO2-directed chest compressions is a novel guided approach to resuscitation that can be as effective as standard CPR optimized with marker, video, and verbal feedback.

    Social laws and religious beliefs throughout history underscore the leaps and bounds that the science of resuscitation has achieved from ancient times until today. The effort to resuscitate victims goes back to ancient history, where death was considered a special form of sleep or an act of God. Biblical accounts of resuscitation attempts are numerous. Resuscitation in the Middle Ages was forbidden, but later during Renaissance, any prohibition against performing cardiopulmonary resuscitation (CPR) was challenged, which finally led to the Enlightenment, where scholars attempted to scientifically solve the problem of sudden death. It was then that the various components of CPR (ventilation, circulation, electricity, and organization of emergency medical services) began to take shape. The 19th century gave way to hallmarks both in the ventilatory support (intubation innovations and the artificial respirator) and the open-and closed chest circulatory support. Meanwhile, novel defibrillation techniques had been employed and ventricular fibrillation described. The groundbreaking discoveries of the 20th century finally led to the scientific framework of CPR. In 1960, mouth-to-mouth resuscitation was eventually combined with chest compression and defibrillation to become CPR as we now know it. This review presents the scientific milestones behind one of medicine's most widely used fields.

    In 2010, the American Heart Association (AHA), the European Resuscitation Council (ERC) and the International Liaison Committee on Resuscitation (ILCOR) issued new guidelines on newborn resuscitation. The new recommendations include: (1) pulse-oximetry for patient assessment during newborn resuscitation; (2) to start resuscitation of term infants with an FiO (2) of 0.21; (3) cardio-respiratory resuscitation with a 3:1 chest compression/inflation ratio for a heart rate ERC and ILCOR used nearly identical literature for their evidence evaluation process. While the AHA and ILCOR guidelines are almost identical, the ERC guidelines differ slightly from the latter with regards to (i) promoting sustained inflations at birth, (ii) promoting a wider range in applied inflations during resuscitation, and (iii) to suction the airways in infants born from meconium stained amniotic fluid, before inflations are given. © Georg Thieme Verlag KG Stuttgart · New York.

    2005-02-01

    Although prehospital cardiac arrest has an incidence of 40-90/100,000 inhabitants per year, there has been a lack of therapeutic options to improve the outcome of these patients. Of all cardiac arrests, 50-70% are caused by acute myocardial infarction (AMI) or massive pulmonary embolism (PE). Thrombolysis has been shown to be a causal and effective therapy in patients with AMI or PE who do not suffer cardiac arrest. In contrast, experience with the use of thrombolysis during cardiac arrest has been limited. Thrombolysis during cardiopulmonary resuscitation (CPR) acts directly on thrombi or emboli causing AMI or PE. In addition, experimental studies suggest that thrombolysis causes an improvement in microcirculatory reperfusion after cardiac arrest. In-hospital and prehospital case series and clinical studies suggest that thrombolysis during CPR may cause a restoration of spontaneous circulation and survival even in patients that have been resuscitated conventionally without success. In addition, there is evidence for an improved neurological outcome in patients receiving a thrombolytic therapy during during CPR. A large randomized, double-blind multicenter trial that has started recently is expected to show if this new therapeutic option can generally improve the prognosis of patients with cardiac arrest.

    To determine whether prolonged (chronic) resuscitation has any beneficial effects on cardiac output and hepatocellular function after trauma-hemorrhage and acute fluid replacement. Acute fluid resuscitation after trauma-hemorrhage restores but does not maintain the depressed hepatocellular function and cardiac output. Male Sprague-Dawley rats underwent a 5-cm laparotomy (i.e., trauma was induced) and were bled to and maintained at a mean arterial pressure of 40 mmHg until 40% of maximal bleed-out volume was returned in the form of Ringer's lactate (RL). The animals were acutely resuscitated with RL using 4 times the volume of maximum bleed-out over 60 minutes, followed by chronic resuscitation of 0, 5, or 10 mL/kg/hr RL for 20 hours. Hepatocellular function was determined by an in vivo indocyanine green clearance technique. Hepatic microvascular blood flow was assessed by laser Doppler flowmetry. Plasma levels of interleukin-6 (IL-6) were determined by bioassay. Chronic resuscitation with 5 mL/kg/hr RL, but not with 0 or 10 mL/kg/hr RL, restored cardiac output, hepatocellular function, and hepatic microvascular blood flow at 20 hours after hemorrhage. The regimen above also reduced plasma IL-6 levels. Because chronic resuscitation with 5 mL/kg/hr RL after trauma-hemorrhage and acute fluid replacement restored hepatocellular function and hepatic microvascular blood flow and decreased plasma levels of IL-6, we propose that chronic fluid resuscitation in addition to acute fluid replacement should be routinely used in experimental studies of trauma-hemorrhage.

    It has been suggested that serum cardiac troponin-T (cTnT) can predict the severity of neonatal hypoxic-ischaemic encephalopathy. We evaluated whether cTnT was better correlated with adrenaline during cardiopulmonary resuscitation (CPR) than with the severity of the insult itself, based on the Apgar scores. Serum cTnT was analysed in 47 asphyxiated newborn infants treated with hypothermia. Blood samples and resuscitation data were collected from medical records, and multiple linear regressions were used to evaluate the effect of the treatment and the Apgar scores on cTnT levels. The infants were divided into three groups: the no CPR group (n = 29) just received stimulation and ventilation, the CPR minus adrenaline group (n = 9) received cardiac compression and ventilation and the CPR plus adrenaline group (n = 9) received complete CPR, including adrenaline. In the univariate analysis, the five and ten-minute Apgar scores were significantly lower in the CPR plus adrenaline group and the cTnT was significantly higher. Multiple regression analysis showed significantly higher cTnT values in the CPR plus adrenaline group, but no significant relationship between cTnT and the Apgar scores. Although cTnT correlated with the severity of the insult in neonatal hypoxic-ischaemic encephalopathy, the levels may have been affected by adrenaline administered during CPR. ©2015 Foundation Acta Paediatrica.

    Background and aim Following high profile errors resulting in patient harm and attracting negative publicity, the healthcare sector has begun to focus on training non-technical teamworking skills as one way of reducing the rate of adverse events. Within the area of resuscitation, two tools have been developed recently aiming to assess these skills – TEAM and OSCAR. The aims of the study reported here were:1.To determine the inter-rater reliability of the tools in assessing performance within the context of resuscitation.2.To correlate scores of the same resuscitation teams episodes using both tools, thereby determining their concurrent validity within the context of resuscitation.3.To carry out a critique of both tools and establish how best each one may be utilised. Methods The study consisted of two phases – reliability assessment; and content comparison, and correlation. Assessments were made by two resuscitation experts, who watched 24 pre-recorded resuscitation simulations, and independently rated team behaviours using both tools. The tools were critically appraised, and correlation between overall score surrogates was assessed. Results Both OSCAR and TEAM achieved high levels of inter-rater reliability (in the form of adequate intra-class coefficients) and minor significant differences between Wilcoxon tests. Comparison of the scores from both tools demonstrated a high degree of correlation (and hence concurrent validity). Finally, critique of each tool highlighted differences in length and complexity. Conclusion Both OSCAR and TEAM can be used to assess resuscitation teams in a simulated environment, with the tools correlating well with one another. We envisage a role for both tools – with TEAM giving a quick, global assessment of the team, but OSCAR enabling more detailed breakdown of the assessment, facilitating feedback, and identifying areas of weakness for future training.

    To evaluate whether a 2-day International Liaison Committee on Resuscitation (ILCOR) Universal Algorithm-based curriculum taught in a tertiary care hospital in Liberia increases local health care provider knowledge and skill comfort level. A combined basic and advanced cardiopulmonary resuscitation (CPR) curriculum was developed for low-resource settings that included lectures and low-fidelity manikin-based simulations. In March 2014, the curriculum was taught to healthcare providers in a tertiary care hospital in Liberia. In a quality assurance review, participants were evaluated for knowledge and comfort levels with resuscitation before and after the workshop. They were also videotaped during simulation sessions and evaluated on standardized performance metrics. Fifty-two hospital staff completed both pre-and post-curriculum surveys. The median score was 45% pre-curriculum and 82% post-curriculum (presuscitation in this low-resource setting.

    Full Text Available The seventh edition of the American Academy of Pediatrics Neonatal Resuscitation Program recommends the use of a cardiac monitor in infants that need resuscitation. Previous trials have shown that EKG heart rate is available before pulse rate from a pulse oximeter. To date no trial has looked at how the availability of electrocardiogram (EKG affects clinical interventions in the delivery room.To determine whether the availability of an EKG heart rate value and tracing to the clinical team has an effect on physiologic measures and related interventions during the stabilization of preterm infants.Forty (40 premature infants enrolled in a neuro-monitoring study (The Neu-Prem Trial: NCT02605733 who had an EKG monitor available were randomized to have the heart rate information from the bedside EKG monitor either displayed or not displayed to the clinical team. Heart rate, oxygen saturation, FiO2 and mean airway pressure from a data acquisition system were recorded every 2 seconds. Results were averaged over 30 seconds and the differences analyzed using two-tailed t-test. Interventions analyzed included time to first change in FiO2, first positive pressure ventilation, first increase in airway pressure, and first intubation.There were no significant differences in time to clinical interventions between the blinded and unblinded group, despite the unblinded group having access to a visible heart rate at 66 +/- 20 compared to 114 +/- 39 seconds for the blinded group (p < .0001. Pulse rate from oximeter was lower than EKG heart rate during the first 2 minutes of life, but this was not significant.EKG provides an earlier, and more accurate heart rate than pulse rate from an oximeter during stabilization of preterm infants, allowing earlier intervention. All interventions were started earlier in the unblinded EKG group but these numbers were not significant in this small trial. Earlier EKG placement before pulse oximeter placement may affect other

    Among patients with cardiac arrest, preliminary data have shown improved return of spontaneous circulation and survival to hospital discharge with the vasopressin-steroids-epinephrine (VSE) combination. To determine whether combined vasopressin-epinephrine during cardiopulmonary resuscitation (CPR) and corticosteroid supplementation during and after CPR improve survival to hospital discharge with a Cerebral Performance Category (CPC) score of 1 or 2 in vasopressor-requiring, in-hospital cardiac arrest. Randomized, double-blind, placebo-controlled, parallel-group trial performed from September 1, 2008, to October 1, 2010, in 3 Greek tertiary care centers (2400 beds) with 268 consecutive patients with cardiac arrest requiring epinephrine according to resuscitation guidelines (from 364 patients assessed for eligibility). Patients received either vasopressin (20 IU/CPR cycle) plus epinephrine (1 mg/CPR cycle; cycle duration approximately 3 minutes) (VSE group, n = 130) or saline placebo plus epinephrine (1 mg/CPR cycle; cycle duration approximately 3 minutes) (control group, n = 138) for the first 5 CPR cycles after randomization, followed by additional epinephrine if needed. During the first CPR cycle after randomization, patients in the VSE group received methylprednisolone (40 mg) and patients in the control group received saline placebo. Shock after resuscitation was treated with stress-dose hydrocortisone (300 mg daily for 7 days maximum and gradual taper) (VSE group, n = 76) or saline placebo (control group, n = 73). Return of spontaneous circulation (ROSC) for 20 minutes or longer and survival to hospital discharge with a CPC score of 1 or 2. Follow-up was completed in all resuscitated patients. Patients in the VSE group vs patients in the control group had higher probability for ROSC of 20 minutes or longer (109/130 [83.9%] vs 91/138 [65.9%]; odds ratio [OR], 2.98; 95% CI, 1.39-6.40; P = .005) and survival to hospital discharge with CPC

    IMPORTANCE: Intrauterine resuscitation techniques during term labor are commonly used in daily clinical practice. Evidence, however, to support the beneficial effect of intrauterine resuscitation techniques on fetal distress during labor is limited and sometimes contradictory. In contrast, some of

    Background Almost half of pediatric third-year residents surveyed in 2000 had never led a resuscitation event. With increasing restrictions on residency work hours and a decline in patient volume in some hospitals, there is potential for fewer opportunities. Purpose Our primary purpose was to test the hypothesis that an unannounced mock resuscitation in a high-fidelity in-situ simulation training program would improve both residents’ self-confidence and observed performance of adopted best practices in neonatal resuscitation. Methods Each pediatric and medicine–pediatric resident in one pediatric residency program responded to an unannounced scenario that required resuscitation of the high fidelity infant simulator. Structured debriefing followed in the same setting, and a second cycle of scenario response and debriefing occurred before ending the 1-hour training experience. Measures included pre- and post-program confidence questionnaires and trained observer assessments of live and videotaped performances. Results Statistically significant pre–post gains for self-confidence were observed for 8 of the 14 NRP critical behaviors (p=0.00–0.03) reflecting knowledge, technical, and non-technical (teamwork) skills. The pre–post gain in overall confidence score was statistically significant (p=0.00). With a maximum possible assessment score of 41, the average pre–post gain was 8.28 and statistically significant (psimulation-based training and significant positive gains in confidence and observed competency-related abilities. Results support the potential for other applications in residency and continuing education. PMID:23522399

    In order to more accurately understand community structure and diversity of actinomycetes in saline-alkali soil from Jiuquan area of Hexi Corridor, the community structure and diversity from three kinds of soil samples (primary, secondary saline alkali soil and farmland soil) were analyzed using uncultured methods. The results showed that the 16S rDNA clone library of actinomycetales from the primary saline-alkali soil belonged to 19 OTUs, Micrococcineae, Propionibacterineae, Corynebacterineae, Frankineae, Pseudonocardineae and unknown groups of Actinomycetales; the 16S r DNA clone library of actinomycetales from the secondary saline-alkali soil belonged to 14 OTUs, Micrococcineae, Propionibacterineae, Corynebacterineae, Frankineae, Pseudonocardineae and unknown groups of Actinomycetales; the 16S rDNA clone library of farmland soil belonged to 7 OTUs, Micrococcineae, Propionibacterineae, Corynebacterineae, Frankineae, Pseudonocardineae and unknown groups of Actinomycetales; Micrococcineae was the common population in the three soils, and also was the dominant population in primary saline alkali soil and farmland soil. The diversity index and rarefaction curves analysis showed that actinomycetes species richness was in order of primary saline-alkali soil > secondary saline-alkali soil > farmland soil. The dilution curves of primary saline-alkali soil and secondary saline-alkali soil were not leveled off, which indicated the actinomycetes diversity in saline-alkali soil was more enriched than the actual. The rich and diverse actinomycetes resources in saline-alkali soil from Jiuquan area of Hexi Corridor provide important data on the actinomycetes ecology distribution research, exploitation and utilization in saline-alkali soil.

    In northeastern Brazil, large swaths of once-productive soils have been severely degraded by soil salinization, but the true extent of the damage has not been assessed. Emerging remote sensing technology based on hyperspectral analysis offers one possibility for large-scale assessment, but it has been unclear to what extent the spectral properties of soils are related to salinity characteristics. The purpose of this study was to characterize the spectral properties of degraded (saline) and non-degraded agricultural soils in northeastern Brazil and determine the extent to which these properties correspond to soil salinity. We took soil samples from 78 locations within a 45,000-km 2 site in Pernambuco State. We used cluster analysis to group the soil samples on the basis of similarities in salinity and sodicity levels, and then obtained spectral data for each group. The physical properties analysis indicated a predominance of the coarse sand fraction in almost all the soil groups, and total porosity was similar for all the groups. The chemical analysis revealed different levels of degradation among the groups, ranging from non-degraded to strongly degraded conditions, as defined by the degree of salinity and sodicity. The soil properties showing the highest correlation with spectral reflectance were the exchangeable sodium percentage followed by fine sand. Differences in the reflectance curves for the various soil groups were relatively small and were not significant. These results suggest that, where soil crusts are not present, significant challenges remain for using hyperspectral remote sensing to assess soil salinity in northeastern Brazil.

    This prospective, randomized, and controlled study examined the effects of normal saline and selenium-enriched hot spring water on experimentally induced rhinosinusitis in rats. The study comprised two control groups (untreated and saline-treated) and three experimental groups of Sprague Dawley rats. The experimental groups received an instillation of lipopolysaccharide (LPS) only, LPS+normal saline (LPS/saline), or LPS+selenium-enriched hot spring water (LPS/selenium). Histopathological changes were identified using hematoxylin-eosin staining. Leakage of exudate was identified using fluorescence microscopy. Microvascular permeability was measured using the Evans blue dye technique. Expression of the Muc5ac gene was measured using reverse transcription-polymerase chain reaction. Mucosal edema and expression of the Muc5ac gene were significantly lower in the LPS/saline group than in the LPS group. Microvascular permeability, mucosal edema, and expression of the Muc5ac gene were significantly lower in the LPS/selenium group than in the LPS group. Mucosal edema was similar in the LPS/selenium group and LPS/saline group, but capillary permeability and Muc5ac expression were lower in the LPS/selenium group. This study shows that normal saline and selenium-enriched hot spring water reduce inflammatory activity and mucus hypersecretion in LPS-induced rhinosinusitis in rats.

    To examine how clinicians practise the principles of beneficence when deciding to allow or deny family presence during resuscitation. Family presence during resuscitation has important benefits for family and is supported by professional bodies and the public. Yet, many clinicians restrict family access to patients during resuscitation, and rationales for decision-making are unclear. Secondary analysis of an existing qualitative data set using deductive category application of content analysis. We analysed 20 interview transcripts from 15 registered nurses, two doctors and three paramedics who had experienced family presence during resuscitation in an Australian hospital. The transcripts were analysed for incidents of beneficent decision-making when allowing or denying family presence during resuscitation. Decision-making around family presence during resuscitation occurred in time poor environments and in the absence of local institutional guidelines. Clinicians appeared to be motivated by doing "what's best" for patients and families when allowing or denying family presence during resuscitation. However, their individual interpretations of "what's best" was subjective and did not always coincide with family preferences or with current evidence that promotes family presence during resuscitation as beneficial. The decision to allow or deny family presence during resuscitation is complex, and often impacted by personal preferences and beliefs, setting norms and tensions between clinicians and consumers. As a result, many families are missing the chance to be with their loved ones at the end of life. The introduction of institutional guidelines and policies would help to establish what safe and effective practice consists of, reduce value-laden decision-making and guide beneficent decision-making. These findings highlight current deficits in decision-making around FPDR and could prompt the introduction of clinical guidelines and policies and in turn promote the

    Full Text Available Background: Transfusion of blood remains the gold standard for fluid resuscitation from hemorrhagic shock. Hemoglobin (Hb within the red blood cell transports oxygen and modulates nitric oxide (NO through NO scavenging and nitrite reductase. Aims: This study was designed to examine the effects of incorporating a novel NO modulator, RRx-001, on systemic and microvascular hemodynamic response after blood transfusion for resuscitation from hemorrhagic shock in a hamster window chamber model. In addition, to RRx-001 the role of low dose of nitrite (1 × 10−9 moles per animal supplementation after resuscitation was studied. Materials and Methods: Severe hemorrhage was induced by arterial controlled bleeding of 50% of the blood volume (BV and the hypovolemic state was maintained for 1 h. The animals received volume resuscitation by an infusion of 25% of BV using fresh blood alone or with added nitrite, or fresh blood treated with RRx-001 (140 mg/kg or RRx-001 (140 mg/kg with added nitrite. Systemic and microvascular hemodynamics were followed at baseline and at different time points during the entire study. Tissue apoptosis and necrosis were measured 8 h after resuscitation to correlate hemodynamic changes with tissue viability. Results: Compared to resuscitation with blood alone, blood treated with RRx-001 decreased vascular resistance, increased blood flow and functional capillary density immediately after resuscitation and preserved tissue viability. Furthermore, in RRx-001 treated animals, both mean arterial pressure (MAP and met Hb were maintained within normal levels after resuscitation (MAP >90 mmHg and metHb <2%. The addition of nitrite to RRx-001 did not significantly improve the effects of RRx-001, as it increased methemoglobinemia and lower MAP. Conclusion: RRx-001 alone enhanced perfusion and reduced tissue damage as compared to blood; it may serve as an adjunct therapy to the current gold standard treatment for resuscitation from

    Neonatal infections carry a heavy burden of morbidity and mortality. Poor practice can result in unintentional colonisation of medical equipment with potentially pathogenic organisms. This study will determine the prevalence and type of bacterial contamination on exposed neonatal resuscitation equipment in different clinical settings and explore simple measures to reduce contamination risk. A survey determined the rates of resuscitation equipment usage. All environmentally exposed items were identified on resuscitaires hospital-wide and swabbed for bacterial contamination. A new cleaning and storage policy was implemented and the prevalence of environmentally exposed equipment re-measured post-intervention. Resuscitation equipment was used in 28% of neonatal deliveries. Bacterial colony forming units were present on 44% of the 236 exposed equipment pieces swabbed. There was no significant difference in contamination rates between equipment types. Coagulase negative staphylococcus was the most prevalent species (59 pieces, 25%) followed by Escherichia coli and Enterobacter cloacae (20 pieces, 9% each). Opened items stored inside plastic remained sterile, whilst those in low-use areas had significantly less contamination than those in high-use areas (22% vs. 51%, P reducing microbial colonisation opportunities. © 2016 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

    In Denmark there are around 3,500 unexpected cardiac arrests (CA) out of hospital each year. There is an unknown number of CA in hospitals. The survival rate after CA outside a hospital in Denmark is 10% after 30 days. There are varying data for the neurological outcome in this group of patients. The purpose of this work is to disseminate new knowledge and to help standardizing the treatment in the group of patients who remain comatose after being resuscitated from CA. Assessment of the prognosis for a patient in this group can be made after 72 hours and a multi-modal approach to the patient is required.

    To explore the similarities and differences in factors that influence nurses' and physicians' decision-making related to family presence during resuscitation. Despite the growing acceptance of family presence during resuscitation worldwide, healthcare professionals continue to debate the risks and benefits of family presence. As many hospitals lack a policy to guide family presence during resuscitation, decisions are negotiated by resuscitation teams, families and patients in crisis situations. Research has not clarified the factors that influence the decision-making processes of nurses and physicians related to inviting family presence. This is the first study to elicit written data from healthcare professionals to explicate factors in decision-making about family presence. Qualitative exploratory-descriptive. Convenience samples of registered nurses (n = 325) and acute care physicians (n = 193) from a Midwestern hospital in the United States of America handwrote responses to open-ended questions about family presence. Through thematic analysis, decision-making factors for physicians and nurses were identified and compared. Physicians and nurses evaluated three similar factors and four differing factors when deciding to invite family presence during resuscitation. Furthermore, nurses and physicians weighted the factors differently. Physicians weighted most heavily the family's potential to disrupt life-saving efforts and compromise patient care and then the family's knowledge about resuscitations. Nurses heavily weighted the potential for the family to be traumatised, the potential for the family to disrupt the resuscitation, and possible family benefit. Nurses and physicians considered both similar and different factors when deciding to invite family presence. Physicians focused on the patient primarily, while nurses focused on the patient, family and resuscitation team. Knowledge of factors that influence the decision-making of interprofessional colleagues

  12. Comparison of the T-piece resuscitator with other neonatal manual ventilation devices: A qualitative review.

    LENUS (Irish Health Repository)

    2012-01-31

    AIM: To review the literature surrounding various aspects of T-piece resuscitator use, with particular emphasis on the evidence comparing the device to other manual ventilation devices in neonatal resuscitation. DATA SOURCES: The Medline, EMBASE, Cochrane databases were searched in April 2011. Ongoing trials were identified using www.clinicaltrials.gov and www.controlled-trials.com. Additional studies from reference lists of eligible articles were considered. All studies including T-piece resuscitator use were eligible for inclusion. RESULTS: Thirty studies were included. There were two randomised controlled trials in newborn infants comparing the devices, one of which addressed short and intermediate term morbidity and mortality outcomes and found no difference between the T-piece resuscitator and self inflating bag. From manikin studies, advantages to the T-piece resuscitator include the delivery of inflating pressures closer to predetermined target pressures with least variation, the ability to provide prolonged inflation breaths and more consistent tidal volumes. Disadvantages include a technically more difficult setup, more time required to adjust pressures during resuscitation, a larger mask leak and less ability to detect changes in compliance. CONCLUSIONS: There is a need for appropriately designed randomised controlled trials in neonates to highlight the efficacy of one device over another. Until these are performed, healthcare providers should be appropriately trained in the use of the device available in their departments, and be aware of its own limitations.

    When frozen, Staphylococcus aureus survives in a sublethally injured state. However, S. aureus can recover at a suitable temperature, which poses a threat to food safety. To elucidate the resuscitation mechanism of freezing survived S. aureus, we used cells stored at -18°C for 90 days as controls. After resuscitating the survived cells at 37°C, the viable cell numbers were determined on tryptic soy agar with 0.6% yeast extract (TSAYE), and the non-injured-cell numbers were determined on TSAYE supplemented with 10% NaCl. The results showed that the total viable cell number did not increase within the first 3 h of resuscitation, but the osmotic regulation ability of freezing survived cells gradually recovered to the level of healthy cells, which was evidenced by the lack of difference between the two samples seen by differential cell enumeration. Scanning electron microscopy (SEM) showed that, compared to late exponential stage cells, some frozen survived cells underwent splitting and cell lysis due to deep distortion and membrane rupture. Transmission electron microscopy (TEM) showed that, in most of the frozen survived cells, the nucleoids (low electronic density area) were loose, and the cytoplasmic matrices (high electronic density area) were sparse. Additionally, a gap was seen to form between the cytoplasmic membranes and the cell walls in the frozen survived cells. The morphological changes were restored when the survived cells were resuscitated at 37°C. We also analyzed the differential proteome after resuscitation using non-labeled high-performance liquid chromatography–mass spectrometry (HPLC-MS). The results showed that, compared with freezing survived S. aureus cells, the cells resuscitated for 1 h had 45 upregulated and 73 downregulated proteins. The differentially expressed proteins were functionally categorized by gene ontology enrichment, KEGG pathway, and STRING analyses.

    The quality of cardiopulmonary resuscitation (CPR) is important to survival after cardiac arrest. Mechanical devices (MD) provide constant CPR, but their effectiveness may be affected by deployment timeliness. To identify the timeliness of the overall and of each essential step in the deployment of a piston-type MD during emergency department (ED) resuscitation, and to identify factors associated with delayed MD deployment by video recordings. Between December 2005 and December 2008, video clips from resuscitations with CPR sessions using a MD in the ED were reviewed using time-motion analyses. The overall deployment timeliness and the time spent on each essential step of deployment were measured. There were 37 CPR recordings that used a MD. Deployment of MD took an average 122.6 ± 57.8s. The 3 most time-consuming steps were: (1) setting the device (57.8 ± 38.3s), (2) positioning the patient (33.4 ± 38.0 s), and (3) positioning the device (14.7 ± 9.5s). Total no flow time was 89.1 ± 41.2s (72.7% of total time) and associated with the 3 most time-consuming steps. There was no difference in the total timeliness, no-flow time, and no-flow ratio between different rescuer numbers, time of day of the resuscitation, or body size of patients. Rescuers spent a significant amount of time on MD deployment, leading to long no-flow times. Lack of familiarity with the device and positioning strategy were associated with poor performance. Additional training in device deployment strategies are required to improve the benefits of mechanical CPR. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Objective: Operations performed with local anesthesia can sometimes be extremely painful and uncomfortable for patients. Our aim was to investigate the optimal analgesic method in saline infusion sonograms.\tMaterials and Methods: This study was performed in our Clinic of Obstetrics and Gynecology between March and August 2011. Ninety-six patients were included. Patients were randomly divided into groups that received saline (controls, group 1, paracervical block (group 2, or paracervical block + intrauterine lidocaine (group 3. In all groups, a visual analogue scale score was performed during the tenaculum placement, while saline was administered, and 30 minutes after the procedure.\tResults: When all the patients were evaluated, the difference in the visual analogue scale scores in premenopausal patients during tenaculum placement, during the saline infusion into the cavity, and 30 minutes following the saline infusion sonography were statistically different between the saline and paracervical block groups, and between the saline and paracervical block + intrauterine lidocaine group. However, there was no statistically significant difference between paracervical block and paracervical block + intrauterine lidocaine groups.\tConclusion: As a result of our study, paracervical block is a safe method to use in premenopausal patients to prevent pain during saline infusion sonography. The addition of intrauterine lidocaine to the paracervical block does not increase the analgesic effect; moreover, it increases the cost and time that the patient stays in the dorsolithotomy position by 3 minutes.

    Leadership skills are described by the American College of Surgeons' Advanced Trauma Life Support (ATLS) course as necessary to provide care for patients during resuscitations. However, leadership is a complex concept, and the tools used to assess the quality of leadership are poorly described, inadequately validated, and infrequently used. Despite its importance, dedicated leadership education is rarely part of physician training programs. The goals of this investigation were the following: 1. Describe how leadership and leadership style affect patient care; 2. Describe how effective leadership is measured; and 3. Describe how to train future physician leaders. We searched the PubMed database using the keywords "leadership" and then either "trauma" or "resuscitation" as title search terms, and an expert in emergency medicine and trauma then identified prospective observational and randomized controlled studies measuring leadership and teamwork quality. Study results were categorized as follows: 1) how leadership affects patient care; 2) which tools are available to measure leadership; and 3) methods to train physicians to become better leaders. We included 16 relevant studies in this review. Overall, these studies showed that strong leadership improves processes of care in trauma resuscitation including speed and completion of the primary and secondary surveys. The optimal style and structure of leadership are influenced by patient characteristics and team composition. Directive leadership is most effective when Injury Severity Score (ISS) is high or teams are inexperienced, while empowering leadership is most effective when ISS is low or teams more experienced. Many scales were employed to measure leadership. The Leader Behavior Description Questionnaire (LBDQ) was the only scale used in more than one study. Seven studies described methods for training leaders. Leadership training programs included didactic teaching followed by simulations. Although programs

    Over-resuscitation is deleterious in many critically ill conditions, including major burns. For more than 15 years, several strategies to reduce fluid administration in burns during the initial resuscitation phase have been proposed, but no single or simple parameter has shown superiority. Fluid administration guided by invasive hemodynamic parameters usually resulted in over-resuscitation. As reported in the previous issue of Critical Care, Sánchez-Sánchez and colleagues analyzed the performance of a 'permissive hypovolemia' protocol guided by invasive hemodynamic parameters (PiCCO, Pulsion Medical Systems, Munich, Germany) and vital signs in a prospective cohort over a 3-year period. The authors' results confirm that resuscitation can be achieved with below-normal levels of preload but at the price of a fluid administration greater than predicted by the Parkland formula (2 to 4 mL/kg per% burn). The classic approach based on an adapted Parkland equation may still be the simplest until further studies identify the optimal bundle of resuscitation goals.

    Full Text Available There is no evidence that the epinephrine-3% hypertonic saline combination is more effective than 3% hypertonic saline alone for treating infants hospitalized with acute bronchiolitis. We evaluated the efficacy of nebulized epinephrine in 3% hypertonic saline.We performed a randomized, double-blind, placebo-controlled clinical trial in 208 infants hospitalized with acute moderate bronchiolitis. Infants were randomly assigned to receive nebulized 3% hypertonic saline with either 3 mL of epinephrine or 3 mL of placebo, administered every four hours. The primary outcome measure was the length of hospital stay.A total of 185 infants were analyzed: 94 in the epinephrine plus 3% hypertonic saline group and 91 in the placebo plus 3% hypertonic saline group. Baseline demographic and clinical characteristics were similar in both groups. Length of hospital stay was significantly reduced in the epinephrine group as compared with the placebo group (3.94 ±1.88 days vs. 4.82 ±2.30 days, P = 0.011. Disease severity also decreased significantly earlier in the epinephrine group (P = 0.029 and P = 0.036 on days 3 and 5, respectively.In our setting, nebulized epinephrine in 3% hypertonic saline significantly shortens hospital stay in hospitalized infants with acute moderate bronchiolitis compared to 3% hypertonic saline alone, and improves the clinical scores of severity from the third day of treatment, but not before.EudraCT 2009-016042-57.

    On the Danish island of Bornholm an intervention was carried out during 2008-2010 aiming at increasing out-of-hospital cardiac arrest (OHCA) survival. The intervention included mass media focus on resuscitation and widespread educational activities. The aim of this study was to compare the bystander BLS rate and survival after OHCA on Bornholm in a 3-year follow-up period after the intervention took place. Data on OHCA on Bornholm were collected from September 28th, 2010 to September 27th, 2013 and compared to data from the intervention period, September 28th, 2008 to September 27th, 2010. The bystander BLS rate for non-EMS witnessed OHCAs with presumed cardiac aetiology was significantly higher in the follow-up period (70% [95% CI 61-77] vs. 47% [95% CI 37-57], p=0.001). AEDs were deployed in 22 (18%) cases in the follow-up period and a shock was provided in 13 cases. There was no significant change in all-rhythm 30-day survival for non-EMS witnessed OHCAs with presumed cardiac aetiology (6.7% [95% CI 3-13] in the follow-up period; vs. 4.6% [95% CI 1-12], p=0.76). In a 3-year follow-up period after an intervention engaging laypersons in resuscitation through mass education in BLS combined with a media focus on resuscitation, we observed a persistent significant increase in the bystander BLS rate for all OHCAs with presumed cardiac aetiology. There was no significant difference in 30-day survival. Copyright © 2014 The Authors. Published by Elsevier Ireland Ltd.. All rights reserved.

    Purpose. To assess the performance of sterile saline solution as the sole contrast agent for percutaneous magnetic resonance imaging (MRI)-guided epidural injections at 1.5 T. Methods. A retrospective analysis of two different techniques of MRI-guided epidural injections was performed with either gadolinium-enhanced saline solution or sterile saline solution for documentation of the epidural location of the needle tip. T1-weighted spoiled gradient echo (FLASH) images or T2-weighted single-shot turbo spin echo (HASTE) images visualized the test injectants. Methods were compared by technical success rate, image quality, table time, and rate of complications. Results. 105 MRI-guided epidural injections (12 of 105 with gadolinium-enhanced saline solution and 93 of 105 with sterile saline solution) were performed successfully and without complications. Visualization of sterile saline solution and gadolinium-enhanced saline solution was sufficient, good, or excellent in all 105 interventions. For either test injectant, quantitative image analysis demonstrated comparable high contrast-to-noise ratios of test injectants to adjacent body substances with reliable statistical significance levels (p < 0.001). The mean table time was 22 ± 9 min in the gadolinium-enhanced saline solution group and 22 ± 8 min in the saline solution group (p = 0.75). Conclusion.

    "Electrical shock is the physiological reaction or injury caused by electric current passing through the human body. It occurs upon contact of a human body part with any source of electricity that causes a sufficient current through the skin, muscles, or hair causing undesirable effects ranging from simple burns to death." Ventricular fibrillation is believed to be the most common cause of death after electrical shock. "The ideal duration of cardiac resuscitation is unknown. Typically prolonged cardiopulmonary resuscitation is associated with poor neurologic outcomes and reduced long term survival. No consensus statement has been made and traditionally efforts are usually terminated after 15-30 minutes." The case under discussion seems worthy of the somewhat detailed description given. It is for a young man who survived after 65 minutes after electrical shock (ES) after prolonged high-quality cardiopulmonary resuscitation (CPR), multiple defibrillations, and artificial ventilation without any sequelae. Early start of adequate chest compressions and close adherence to advanced cardiac life support protocols played a vital role in successful CPR.

    The metabolic syndrome and associated fatty liver disease are thought to contribute to poor outcomes in trauma patients. Experimentally, obesity compromises liver blood flow. We sought to correlate the effect of obesity, injury severity, and liver dysfunction with trauma outcomes. We hypothesized that obesity-related liver dysfunction could be mitigated with the novel technique of adjunctive direct peritoneal resuscitation (DPR). This study has clinical and experimental arms. The clinical study was a case-controlled retrospective analysis of ICU trauma patients (n = 72 obese, n = 187 nonobese). The experimental study was a hemorrhagic shock model in obese rats to assess the effect of DPR on liver blood flow, liver function, and inflammatory mediators. In trauma patients, univariate and multivariate analyses demonstrated increasing mortality (p trauma outcomes regardless of injury severity. Obesity-related liver and renal dysfunction is aggravated by injury severity. In an obese rat model of resuscitated hemorrhagic shock, the addition of DPR abrogates trauma-induced liver, renal, and inflammatory responses. We conclude that the addition of DPR to the clinical resuscitation regimen will benefit the obese trauma patient. Published by Elsevier Inc.

    Full Text Available Resuscitation plans (RP are an important clinical indicator relating to care at the end of life in paediatrics. A retrospective review of the medical records of children who had been referred to the Royal Children’s Hospital, Brisbane, Australia who died in the calendar year 2011 was performed. Of 62 records available, 40 patients (65% had a life limiting condition and 43 medical records (69% contained a documented RP. This study demonstrated that both the underlying condition (life-limiting or life-threatening and the setting of care (Pediatric Intensive Care Unit or home influenced the development of resuscitation plans. Patients referred to the paediatric palliative care (PPC service had a significantly longer time interval from documentation of a resuscitation plan to death and were more likely to die at home. All of the patients who died in the paediatric intensive care unit (PICU had a RP that was documented within the last 48 h of life. Most RPs were not easy to locate. Documentation of discussions related to resuscitation planning should accommodate patient and family centered care based on individual needs. With varied diagnoses and settings of care, it is important that there is inter-professional collaboration, particularly involving PICU and PPC services, in developing protocols of how to manage this difficult but inevitable clinical scenario.

    Hospitalized infants requiring cardiopulmonary resuscitation (CPR) represent a high-risk group. Recent data on risk factors for mortality following CPR in this population are lacking. We hypothesized that infant demographic characteristics, diagnoses, and levels of cardiopulmonary support at the time of CPR requirement would be associated with survival to hospital discharge following CPR. Retrospective cohort study. All infants receiving CPR on day of life 2 to 120 admitted to 348 Pediatrix Medical Group neonatal intensive care units from 1997 to 2012. We collected data on demographics, interventions, center volume, and death prior to NICU discharge. We evaluated predictors of death after CPR using multivariable logistic regression with generalized estimating equations to account for clustering of the data by center. Our cohort consisted of 2231 infants receiving CPR. Of these, 1127 (51%) survived to hospital discharge. Lower gestational age, postnatal age, 5-min APGAR, congenital anomaly, and markers of severity of illness were associated with higher mortality. Mortality after CPR did not change significantly over time (Cochran-Armitage test for trend p=0.35). Mortality following CPR in infants is high, particularly for less mature, younger infants with congenital anomalies and those requiring cardiopulmonary support prior to CPR. Continued focus on at risk infants may identify targets for CPR prevention and improve outcomes. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    This research investigated leadership and effectiveness of teams operating in a high-velocity environment, specifically trauma resuscitation teams. On the basis of the literature and their own ethnographic work, the authors proposed and tested a contingency model in which the influence of leadership on team effectiveness during trauma resuscitation differs according to the situation. Results indicated that empowering leadership was more effective when trauma severity was low and when team experience was high. Directive leadership was more effective when trauma severity was high or when the team was inexperienced. Findings also suggested that an empowering leader provided more learning opportunities than did a directive leader. The major contribution of this article is the linkage of leadership to team effectiveness, as moderated by relatively specific situational contingencies. ((c) 2005 APA, all rights reserved).

  8. Is pulseless electrical activity a reason to refuse cardiopulmonary resuscitation with ECMO support?

    Pabst, Dirk; Brehm, Christoph E

    2018-04-01

    Cardiopulmonary resuscitation with ECMO support (ECPR) has shown to improve outcome in patients after cardiac arrest under resuscitation. Most current recommendations for ECPR do not include patients with a non-shockable rhythm such as PEA and asystole. The aim of this study was to investigate the outcome of 3 patient groups separated by initial rhythm at time of ECMO placement during CPR: asystole, PEA and shockable rhythm. We made a retrospective single-center study of adults who underwent ECPR for in-hospital cardiac arrest between June 2008 and January 2017. Outcome and survival were identified in 3 groups of patients regarding to the heart rhythm at the time decision for ECMO support was made: 1. patients with asystole, 2. patients with pulseless electrical activity, 3. patients with a shockable rhythm. 63 patients underwent ECPR in the mentioned time frame. Five patients were excluded due to incomplete data. Under the 58 included patients the number of cases for asystole, PEA, shockable rhythm was 7, 21 and 30 respectively. The means of CPR-time in these groups were 37, 41 and 37min. Survival to discharge was 0.0%, 23.8% and 40.0% respectively (p=0.09). All survivors to discharge had a good neurological outcome, defined as cerebral performance category 1or 2. Survival to discharge in patients with PEA as initial rhythm at the time of decision for ECPR is 23.8% while no patients with asystole as initial rhythm survived discharge. Patients with PEA should be carefully considered for ECPR. Copyright © 2017 Elsevier Inc. All rights reserved.

    Junior physicians are sometimes sent in ambulances with critically ill patients who require urgent transfer to another hospital. Unfamiliar surroundings and personnel, time pressure, and lack of experience may imply a risk of insufficient treatment during transportation as this can cause the physician to loose the expected overview of the situation. While health care professionals are expected to follow complex algorithms when resuscitating, stress can compromise both solo-performance and teamwork. To examine whether inter-hospital resuscitation improved with a structured team briefing between physician and ambulance crew in preparation for transfer vs. review of resuscitation guidelines. The effect parameters were physician team leadership (requesting help, delegating tasks), time to resuscitation key elements (chest compressions, defibrillation, ventilations, medication, or a combination of these termed "the first meaningful action"), and hands-off ratio. 46 physicians graduated within 5 years. A simulation intervention study with a control group and two interventions (structured team briefing or review of guidelines). Scenario: Cardiac arrest during simulated inter-hospital transfer. Forty-six candidates participated: 16 (control), 13 (review), and 17 (team briefing). Reviewing guidelines delayed requesting help to 162 seconds, compared to 21 seconds in control and team briefing groups (p = 0.021). Help was not requested in 15% of cases; never requesting help was associated with an increased hands-off ratio, from 39% if the driver's assistance was requested to 54% if not (p delegating tasks and warrants the need for further studies focusing on how to avoid this cognitive impairment.

    Quality standards no longer allow physicians to delay discussing goals of care and resuscitation. We propose 2 novel strategies for discussing goals and resuscitation on admission. The first, SPAM (determine Surrogate decision maker, determine resuscitation Preferences, Assume full care, and advise them to expect More discussion especially with clinical changes), helps clinicians discover patient preferences and decision maker during routine admissions. The second, UFO-UFO (Understand what they know, Fill in knowledge gaps, ask about desired Outcomes, Understand their reasoning, discuss the spectrum Feasible Outcomes), helps patients with poor or uncertain prognosis or family-team conflict. Using a challenging case example, this article illustrates how SPAM and UFO-UFO can help clinicians have patient-centered resuscitation and goals of care discussions at the beginning of care.

    Early rapid fluid resuscitation (boluses) in African children with severe febrile illnesses increases the 48-hour mortality by 3.3% compared with controls (no bolus). We explored the effect of boluses on 48-hour all-cause mortality by clinical presentation at enrolment, hemodynamic changes over the first hour, and on different modes of death, according to terminal clinical events. We hypothesize that boluses may cause excess deaths from neurological or respiratory events relating to fluid overload. Pre-defined presentation syndromes (PS; severe acidosis or severe shock, respiratory, neurological) and predominant terminal clinical events (cardiovascular collapse, respiratory, neurological) were described by randomized arm (bolus versus control) in 3,141 severely ill febrile children with shock enrolled in the Fluid Expansion as Supportive Therapy (FEAST) trial. Landmark analyses were used to compare early mortality in treatment groups, conditional on changes in shock and hypoxia parameters. Competing risks methods were used to estimate cumulative incidence curves and sub-hazard ratios to compare treatment groups in terms of terminal clinical events. Of 2,396 out of 3,141 (76%) classifiable participants, 1,647 (69%) had a severe metabolic acidosis or severe shock PS, 625 (26%) had a respiratory PS and 976 (41%) had a neurological PS, either alone or in combination. Mortality was greatest among children fulfilling criteria for all three PS (28% bolus, 21% control) and lowest for lone respiratory (2% bolus, 5% control) or neurological (3% bolus, 0% control) presentations. Excess mortality in bolus arms versus control was apparent for all three PS, including all their component features. By one hour, shock had resolved (responders) more frequently in bolus versus control groups (43% versus 32%, P <0.001), but excess mortality with boluses was evident in responders (relative risk 1.98, 95% confidence interval 0.94 to 4.17, P = 0.06) and 'non-responders' (relative risk 1

    The degree to which laboratory derived measures of salinity tolerance reflect the field distributions of freshwater biota is uncertain. In this paper we compare laboratory-derived acute salinity tolerance (LC{sub 50} values) of freshwater macroinvertebrates (range 5.5-76 mS/cm) and fish (range 2.7-82 mS/cm) from southeastern Australia with the salinity from which they have been collected in the field. Only 4% of the macroinvertebrates were collected at salinity levels substantially higher than their 72-h LC{sub 50} obtained from directly transferring animals from low salinity water to the water they were tested (direct transfer LC{sub 50}). This LC{sub 50} value was correlated with the maximum salinity at which a species had been collected. For common macroinvertebrates, the maximum field salinity was approximated by the direct transfer 72-h LC{sub 50}. For adult freshwater fish, 21% of species were collected at salinities substantially greater than their acute direct transfer LC{sub 50} and there was a weak relationship between these two variables. Although there was a weak correlation between the direct transfer LC{sub 50} of early life stages of freshwater fish and the maximum field salinity, 58% of the field distribution were in higher than their LC{sub 50} values. In contrast, LC{sub 50} determined from experiments that acclimated adult fish to higher salinity (slow acclimation) provided a better indication of the field distribution: with only one fish species (7%) being in conflict with their maximum field salinity and a strong positive relationship between these variables. This study shows that laboratory measures of acute salinity tolerance can reflect the maximum salinity that macroinvertebrate and fish species inhabit and are consistent with some anecdotal observations from other studies. - Acute laboratory salinity tolerances relate to maximum salinity where organisms occur in nature.

    1997-06-06

    In light of the medically relevant features of the ancient Egyptian mouth-opening ceremony, the question of the effectiveness of medical practices in Egypt thousands of years ago is examined, whereby the religious and cultural framework also plays a significant role. In the Land on the Nile myth and reality clearly generated special conditions which favoured the systematic treatment of questions of resuscitation. Numerous examples show that this had practical consequences in the area of everyday medicine. In addition, rebirth and resurrection were central elements of the cult of the dead which had exact medical equivalents. These equivalents may demonstrate the advanced state of resuscitation practices in Egypt at that time. In this context, a reconstruction of an ancient Egyptian mouth-opening instrument is presented. In the cult of the dead, this instrument played a role which can be compared to the function of a modern laryngoscope. It appears possible that at the time of the pyramids the Egyptians already had an understanding of the technology required to perform instrument-aided artificial respiration. Whether or not they actually possessed a fundamental knowledge of the principles of cardio-pulmonary resuscitation remains unclear. Nevertheless, the astonishingly functional characteristics of the reconstructed mouth-opening instrument suggest that it was developed for more than purely symbolic purposes.

    Sodium bicarbonate is frequently used for patients unresponsive to cardiopulmonary resuscitation (CPR). Its use may be associated with longer resuscitation duration as well as more severe metabolic acidosis. We applied a new analytical method based on a matched case-control study design to control for the potential confounders. Out-of-hospital cardiac arrest patients resuscitated in an emergency department for at least 20 minutes, unless there was any return of spontaneous circulation (ROSC) within the time frame, were analyzed. Patients without ROSC for 20 minutes of CPR were matched to those with ROSC based on initial bicarbonate level categorized using cutoff points of 10, 15, 20, 25, and 30 mEq/L, and their observation durations were trimmed to match their pairs. The association between sodium bicarbonate and ROSC was examined using conditional logistic regression analysis. Two matched groups, one with ROSC and the other without (both n = 258), were generated. Sodium bicarbonate administration and its total cumulative dose were significantly associated with an increased ROSC, with odds ratios for ROSC of 1.86 (95% confidence interval [CI], 1.09-3.16; P = .022) and 1.18 (per 20 mEq; 95% CI, 1.04-1.33; P = .008), respectively. The positive associations remained unchanged after multivariable adjustment, with odds ratios for ROSC of 2.49 (95% CI, 1.33-4.65; P = .004) and 1.27 (95% CI, 1.11-1.47; P = .001), respectively. Sodium bicarbonate administration during CPR in emergency department was associated with increased ROSC. Copyright © 2015 Elsevier Inc. All rights reserved.

    It is very important to estimate brain functional capacity immediately after successful cardiopulmonary resuscitation (CPR) to determine subsequent treatment strategy and to elucidate the pathophysiology of patients with post-resuscitative encephalopathy. However, computed tomography scanning, electric encephalography and conventional magnetic resonance imaging do not contribute significantly to the assessment of brain functions immediately after CPR. Recently, diffusion-weighted magnetic resonance imaging (DW-MRI) has been applied to the patients with post-resuscitative encephalopathy. However, no papers have described serial clinical and repeated DW-MRI studies of patients during the acute phase of post-resuscitative encephalopathy. Moreover, in some cases, high signal intensity in the cortex after CPR is indistinguishable from normal cortex. Thus, we tried to apply high b-value DW-MRI to estimate the brain function of patients with post-resuscitative encephalopathy. This study was performed on 11 patients with post-resuscitative encephalopathy and 5 healthy volunteers as controls. DW-MRI was performed using GYROSCAN 1.5 Tesla MR imager (Philips) with single-shot echo-planner imaging sequences performed 3 times, first within 24 hours after CPR, second between day 3 to 6, and third more than 7 days after CPR. And we tested the usefulness of DW-MRI at 800, 1000, 1500, 2000 and 3000 in b value. Five patients survived, one fully recovered and four remained in a vegetative state. The other six died with clinical brain death. The first DW-MRI revealed in high signal intensity in the frontal and the parietal lobes in all patients who eventually progressed to a vegetative state or brain death. This result was much more wide-spread in the latter patients, while it was never seen in the patients who recovered fully. The high signal intensity areas increased in follow-up DW-MRI studies. The signal intensity remained high in some parts, while it decreased in other parts with

    The purpose of this study was to prospectively evaluate the effect of benzyl alcohol, a common preservative in normal saline, on postprocedural pain after intraarticular injection for direct shoulder MR arthrography. From April 2011 through January 2013, 138 patients underwent direct shoulder MR arthrography. Using the Wong-Baker Faces Pain Scale, patients were asked to report their shoulder pain level immediately before and immediately after the procedure and then were contacted by telephone 6, 24, and 48 hours after the procedure. Fourteen patients did not receive the prescribed amount of contrast agent for diagnostic reasons or did not complete follow-up. Sixty-two patients received an intraarticular solution including preservative-free normal saline (control group) and 62 patients received an intraarticular solution including normal saline with 0.9% benzyl alcohol as a contrast diluent (test group). Patients were randomized as to which intraarticular diluent they received. Fluoroscopic and MR images were reviewed for extracapsular contrast agent administration or extravasation, full-thickness rotator cuff tears, and adhesive capsulitis. The effect of preservative versus control on pain level was estimated with multiple regression, which included time after procedure as the covariate and accounted for repeated measures over patients. Pain scale scores were significantly (p = 0.0382) higher (0.79 units; 95% CI, 0.034-1.154) with benzyl alcohol preservative compared with control (saline). In both study arms, the pain scale scores decreased slightly after the procedure, increased by roughly 1 unit over baseline for the test group and 0.3 unit over baseline for the control group by 6 hours after the procedure, were 0.50 unit over baseline for the test group and 0.12 unit over baseline for the control group at 24 hours, then fell to be slightly greater than baseline at 48 hours with benzyl alcohol and slightly less than baseline without benzyl alcohol.

    Sepsis is an increasing problem in the practice of emergency medicine as the prevalence is increasing and optimal care to reduce mortality requires significant resources and time. Evidence-based septic shock resuscitation strategies exist, and rely on appropriate recognition and diagnosis, but variation in adherence to the recommendations and therefore outcomes remains. Our objective was to perform a multi-institutional prospective risk-assessment, using failure mode effects and criticality analysis (FMECA), to identify high-risk failures in ED sepsis resuscitation. We conducted a FMECA, which prospectively identifies critical areas for improvement in systems and processes of care, across three diverse hospitals. A multidisciplinary group of participants described the process of emergency department (ED) sepsis resuscitation to then create a comprehensive map and table listing all process steps and identified process failures. High-risk failures in sepsis resuscitation from each of the institutions were compiled to identify common high-risk failures. Common high-risk failures included limited availability of equipment to place the central venous catheter and conduct invasive monitoring, and cognitive overload leading to errors in decision-making. Additionally, we identified great variability in care processes across institutions. Several common high-risk failures in sepsis care exist: a disparity in resources available across hospitals, a lack of adherence to the invasive components of care, and cognitive barriers that affect expert clinicians' decision-making capabilities. Future work may concentrate on dissemination of non-invasive alternatives and overcoming cognitive barriers in diagnosis and knowledge translation.

  3. Cardiopulmonary Resuscitation: Unusual Techniques for Unusual Situations

    Directory of Open Access Journals (Sweden)

    2018-01-01

    Full Text Available Background: The cardiopulmonary resuscitation (CPR in prone position has been dealt with in 2010 American Heart Association (AHA guidelines but have not been reviewed in 2015 guidelines. The guidelines for patients presenting with cardiac arrest under general anesthesia in lateral decubitus position and regarding resuscitation in confined spaces like airplanes are also not available in AHA guidelines. This article is an attempt to highlight the techniques adopted for resuscitation in these unusual situations. Aims: This study aims to find out the methodology and efficacy in nonconventional CPR approaches such as CPR in prone, CPR in lateral position, and CPR in confined spaces. Methods: We conducted a literature search using MeSH search strings such as CPR + Prone position, CPR + lateral Position, and CPR + confined spaces. Results: No randomized controlled trials are available. The literature search gives a handful of case reports, some simulation- and manikin-based studies but none can qualify for class I evidence. The successful outcome of CPR performed in prone position has shown compressions delivered on the thoracic spine with the same rate and force as they were delivered during supine position. A hard surface is required under the patient to provide uniform force and sternal counter pressure. Two rescuer technique for providing successful chest compression in lateral position has been documented in the few case reports published. Over the head CPR and straddle (STR, CPR has been utilized for CPR in confined spaces. Ventilation in operating rooms was taken care by an advanced airway in situ. Conclusion: A large number of studies of high quality are required to be conducted to determine the efficacy of CPR in such positions.

    Recent evidence suggests that patient outcomes are not affected by the offering of family presence during resuscitation (FPDR), and that psychological outcomes are neutral or improved in family members of adult patients. The exclusion of family members from the resuscitation area should, therefore, be reassessed. The present Canadian Critical Care Society position paper is designed to help clinicians and institutions decide whether to incorporate FPDR as part of their routine clinical practice, and to offer strategies to implement FPDR successfully. The authors conducted a literature search of the perspectives of health care providers, patients and families on the topic of FPDR, and considered the relevant ethical values of beneficence, nonmaleficence, autonomy and justice in light of the clinical evidence for FPDR. They reviewed randomized controlled trials and observational studies of FPDR to determine strategies that have been used to screen family members, select appropriate chaperones and educate staff. FPDR is an ethically sound practice in Canada, and may be considered for the families of adult and pediatric patients in the hospital setting. Hospitals that choose to implement FPDR should develop transparent policies regarding which family members are to be offered the opportunity to be present during the resuscitation. Experienced chaperones should accompany and support family members in the resuscitation area. Intensive educational interventions and increasing experience with FPDR are associated with increased support for the practice from health care providers. FPDR should be considered to be an important component of patient and family-centred care.

    Full Text Available Patients that survive hemorrhage and resuscitation (H/R may develop a systemic inflammatory response syndrome (SIRS that leads to dysfunction of vital organs (multiple organ dysfunction syndrome, MODS. SIRS and MODS may involve mitochondrial dysfunction. Under pentobarbital anesthesia, C57BL6 mice were hemorrhaged to 30 mm Hg for 3 h and then resuscitated with shed blood plus half the volume of lactated Ringer’s solution containing minocycline, tetracycline (both 10 mg/kg body weight or vehicle. Serum alanine aminotransferase (ALT, necrosis, apoptosis and oxidative stress were assessed 6 h after resuscitation. Mitochondrial polarization was assessed by intravital microscopy. After H/R with vehicle or tetracycline, ALT increased to 4538 U/L and 3999 U/L, respectively, which minocycline decreased to 1763 U/L (P<0.01. Necrosis and TUNEL also decreased from 24.5% and 17.7 cells/field, respectively, after vehicle to 8.3% and 8.7 cells/field after minocycline. Tetracycline failed to decrease necrosis (23.3% but decreased apoptosis to 9 cells/field (P<0.05. Minocycline and tetracycline also decreased caspase-3 activity in liver homogenates. Minocycline but not tetracycline decreased lipid peroxidation after resuscitation by 70% (P<0.05. Intravital microscopy showed that minocycline preserved mitochondrial polarization after H/R (P<0.05. In conclusion, minocycline decreases liver injury and oxidative stress after H/R by preventing mitochondrial dysfunction.

    Sodium bicarbonate administration during cardiopulmonary resuscitation (CPR) is controversial. Current guidelines recommend sodium bicarbonate injection in patients with existing metabolic acidosis, but clinical trials, particularly, those involving patients with acidosis, are limited. We aimed to evaluate the efficacy of sodium bicarbonate administration in out-of-hospital cardiac arrest (OHCA) patients with severe metabolic acidosis during prolonged CPR. Prospective, double-blind, randomized placebo-controlled pilot trial was conducted between January 2015 and December 2015, at a single center emergency department (ED). After 10 minutes of CPR, patients who failed to achieve return of spontaneous circulation (ROSC) and with severe metabolic acidosis (pH<7.1 or bicarbonate <10 mEq/L) were enrolled. Sodium bicarbonate (n=25) or normal saline (n=25) were administered. The primary end point was sustained ROSC. The secondary end points were the change of acidosis and good neurologic survival. Sodium bicarbonate group had significant effect on pH (6.99 vs. 6.90, P=0.038) and bicarbonate levels (21.0 vs. 8.0 mEq/L, P=0.007). However, no significant differences showed between sodium bicarbonate and placebo groups in sustained ROSC (4.0% vs. 16.0%, P=0.349) or good neurologic survival at 1 month (0.0% vs. 4.0%, P=1.000). The use of sodium bicarbonate improved acid-base status, but did not improve the rate of ROSC and good neurologic survival. We could not draw a conclusion, but our pilot data could be used to design a larger trial to verify the efficacy of sodium bicarbonate. NCT02303548 (http://www.ClinicalTrials.gov).

    Aim: To determine whether the use of normal saline for sealing the needle track can reduce the incidence of pneumothorax and chest tube placement after computed tomography (CT)-guided lung biopsy. Materials and methods: A prospective, randomised, controlled trial enrolling 322 patients was conducted. All patients were randomly assigned to one of two groups: those in whom the needle track was not sealed with normal saline (n=161, Group A) and those who did receive normal saline (n=161, Group B). CT-guided biopsy was performed with coaxial technique. Normal saline, which ranged from 1–3 ml, was injected while the trocar needle was being withdrawn. Patient characteristics, lesion, and procedure variables were analysed as potential risk variables for occurrence of pneumothorax and chest tube placement. Results: The incidence of pneumothorax was 26.1% in Group A and 6.2% in Group B (p<0.001). Nine patients in Group A and one patient in Group B required chest tube placement (p=0.010). Using multiple logistic regression analysis, smaller lesion size, greater needle–pleural angle, longer lesion–pleural distance, presence of emphysema, and no sealing the needle track with normal saline were significantly associated with an increased risk of pneumothorax, and that the latter three factors were also associated with an increased risk of pneumothorax requiring chest tube placement. Conlusion: Normal saline for sealing the needle track significantly reduces the incidence of pneumothorax and prevents subsequent chest tube placement after CT-guided lung biopsy. - Highlights: • Normal saline is an effective sealant for use in lung biopsy. • This technique reduced the incidence of pneumothorax and chest tube placement. • This technique should be recommended for CT-guided lung biopsy.

    Full Text Available With the increasing number of old people in all western countries and increasing life expectancy at birth, many seniors spend the last period of their life with various afflictions that may lead to cardiac arrest. Bystander cardiopulmonary resuscitation (CPR increases survival rates. Octogenarians are the fastest growing segment of the population and despite empirical evidence that CPR is of questionable effectiveness in seniors with comorbidities, it is still the only treatment among life-sustaining ones. Cardiopulmonary resuscitation is frequently unsuccessful, but if survival is achieved, a fairly good quality of life can be expected. Various papers analyzed the effect of CPR in hospitalized patients or in cardiac arrest occurring at home or in public places, while less is known about events occurring in the emergency room (ER. We performed a retrospective analysis of cardiac arrest events occurred in ER within 54 months: we analyzed 415,001 records of ER visits (from 01/01/1999 to 30/06/2003 in San Giovanni Addolorata Hospital. Data were analyzed in terms of age and outcome. We identified 475 records with the outcome of death in ER or death on arrival. Out of them, we selected 290 medical records which had sufficient data to be analyzed. Of the 290 patients evaluated, 225 died in ER, 18 were deemed to die on arrival, and 47 survived the cardiac arrest and were admitted to intensive care unit (ICU. The overall mortality was 0.11%, while the incidence of the selected events was 0.072%. The mean age of the analyzed population was 71.3 years. The only possible diagnosis was often cardiac arrest, though most of the times we could specify and group the diagnosis even better. The analysis of the procedures showed that cardiac arrest treated by direct current (DC shock was similarly distributed in different age groups, and no difference was detectable between the two groups. The mean age of the patients who underwent tracheal intubation (TI was

    A gene encoding the resuscitation-promoting factor (Rpf) from Salmonella Typhimurium LT2 was cloned and characterized. The amino acid sequence encoded by S. Typhimurium LT2 rpf gene shares 24.2% homology with Micrococcus luteus Rpf, which is secreted by growing cells, and required to resuscitate from viable but non-culturable (VNC) state. The S. Typhimurium LT2 rpf gene is 696 bp long, and shared a conserved segment with Salmonella enterica serovar Oranienburg (99.4%). Recombinant Rpf (rRpf) proteins of S. Typhimurium LT2 after expression in E. coli BL21 harboring the pET15-b plasmid was approximately 25 kDa. Since S. Oranienburg cells are relatively quick to enter the VNC state just after incubating in the presence of 7% NaCl at 37 degrees C for 3 days, we evaluated the biological effect of rRpf by using S. Oranienburg VNC cells. The rRpf not only promoted proliferation but also induced resuscitation of VNC cells to the culturable state in a dose-dependent manner. Therefore, rRpf may be useful for detection of bacterial contaminants present in the VNC form in food samples and the environment.

    Cardiac rehabilitation may provide an ideal environment to train high-risk cardiac patients and their families in cardiopulmonary resuscitation (CPR). However, whether this training is currently offered is unknown. The aims of this study were to: 1) describe the prevalence of CPR training in cardiac rehabilitation programs in Australia and New Zealand (NZ); and 2) examine perceived barriers and attitudes of cardiac rehabilitation coordinators towards providing CPR training. We conducted a cross-sectional online survey of Australian and NZ cardiac rehabilitation coordinators. We received 253 completed surveys (46.7% response rate) (Australia n=208, NZ n=45). Cardiopulmonary resuscitation training was included in 23.9% of Australian programs and 56.6% in NZ. Common barriers to CPR training included lack of resources (49.7%) and a lack of awareness to provide CPR training for this high-risk group (33.7%). The majority of coordinators believed that lay people should be trained in CPR (96.3%) and were comfortable with recommending CPR training to this high-risk group (89.4%). While cardiac rehabilitation coordinators have positive attitudes towards CPR training, it is not currently part of most programs - particularly in Australia. Organisations formulating cardiac rehabilitation recommendations and guidelines should give consideration to include the provision of CPR training.

    Our goal was to garner opinions regarding neonatal resuscitation training for obstetric physicians. We sought to evaluate obstacles to neonatal resuscitation training for obstetric physicians and possible solutions for implementation challenges. We distributed a national survey via email to all neonatal-perinatal medicine fellowship directors and obstetrics & gynecology residency program directors in the United States. This survey was designed by a consensus method. Ninety-eight (53%) obstetric and fifty-seven (51%) neonatal program directors responded to our surveys. Eighty-eight percent of neonatologists surveyed believe that obstetricians should be neonatal resuscitation program (NRP) certified. The majority of surveyed obstetricians (>89%) believe that obstetricians should have some neonatal resuscitation training. Eighty-six percent of obstetric residents have completed training in NRP, but only 19% of obstetric attendings are NRP certified. Major barriers to NRP training that were identified include time, lack of national requirement, lack of belief it is helpful, and cost. Most obstetric attendings are not NRP certified, but the majority of respondents believe that obstetric providers should have some neonatal resuscitation training. Our study demonstrates that most respondents support a modified neonatal resuscitation course for obstetric physicians.

    Tilapias are a group of freshwater species, which vary in their ability to adapt to high salinity water. Osmotic regulation in fish is conducted mainly in the gills, kidney, and gastrointestinal tract (GIT). The mechanisms involved in ion and water transport through the GIT is not well-characterized, with only a few described complexes. Comparing the transcriptome of the anterior and posterior intestinal sections of a freshwater and saltwater adapted fish by deep-sequencing, we examined the salinity adaptation of two tilapia species: the high salinity-tolerant Oreochromis mossambicus (Mozambique tilapia), and the less salinity-tolerant Oreochromis niloticus (Nile tilapia). This comparative analysis revealed high similarity in gene expression response to salinity change between species in the posterior intestine and large differences in the anterior intestine. Furthermore, in the anterior intestine 68 genes were saltwater up-regulated in one species and down-regulated in the other species (47 genes up-regulated in O. niloticus and down-regulated in O. mossambicus, with 21 genes showing the reverse pattern). Gene ontology (GO) analysis showed a high proportion of transporter and ion channel function among these genes. The results of this study point to a group of genes that differed in their salinity-dependent regulation pattern in the anterior intestine as potentially having a role in the differential salinity tolerance of these two closely related species.

    Effective ventilation is crucial to save non-breathing newborns. We compared standard equipment for newborn resuscitation to a new Upright bag, in an area with high neonatal mortality. Newborns requiring resuscitation at Haydom Lutheran Hospital, Tanzania, were ventilated with 230ml standard or 320ml Upright bag-mask by weekly non-blinded block randomisation. A Laerdal Newborn Resuscitation Monitor collected ventilation data through a flow sensor between mask and bag and heart rate with electrocardiography electrodes. Primary outcome was expiratory tidal volume per birth weight. Of 6110 babies born, 136 randomised to standard bag-mask and 192 to Upright, both groups had similar birth weight, gestational age, Apgar scores, gender, and mode of delivery. Compared to standard bag-mask, Upright gave higher median expiratory tidal volume (8.6ml/kg (IQR: 3.5-13.8) vs. 10.0ml/kg (IQR: 4.3-16.8) difference ratio 1.29, 95%CI 1.05, 1.58, p=0.014)), increased mean airway and peak inspiratory pressures, and higher early expired CO 2 (median at 20s 4.2% vs. 3.2%, p=0.0099). Clinical outcome 30min post-delivery was normal in 44% with standard versus 57% with Upright (p=0.016), but similar at 24h. Upright provided higher expired tidal volume, MAP, PIP and early ECO 2 than the standard bag. Clinical outcome differed at 30min, but not at 24h. Larger volume of Upright than standard bag can be an important factor. The results are relevant for low- and high-income settings as ventilatory and heart rate parameters during resuscitation of newborns are rarely reported.

    There is an increasing interest in human factors within the healthcare environment reflecting the understanding of their impact on safety. The aim of this paper is to explore how human factors might be taught on resuscitation courses, and improve course outcomes in terms of improved mortality and morbidity for patients. The delivery of human factors training is important and this review explores the work that has been delivered already and areas for future research and teaching. Medline was searched using MESH terms Resuscitation as a Major concept and Patient or Leadership as core terms. The abstracts were read and 25 full length articles reviewed. Critical incident reporting has shown four recurring problems: lack of organisation at an arrest, lack of equipment, non functioning equipment, and obstructions preventing good care. Of these, the first relates directly to the concept of human factors. Team dynamics for both team membership and leadership, management of stress, conflict and the role of debriefing are highlighted. Possible strategies for teaching them are discussed. Four strategies for improving human factors training are discussed: team dynamics (including team membership and leadership behaviour), the influence of stress, debriefing, and conflict within teams. This review illustrates how human factor training might be integrated further into life support training without jeopardising the core content and lengthening the courses.

    Salinity plays a key role in the determination of the thermodynamic properties of seawater and the new TEOS-101 standard provides a consistent and effective approach to dealing with relationships between salinity and these thermodynamic properties. However, there are a number of practical issues that arise in the application of TEOS-10, both in terms of accuracy and scope, including its use in the reduction of field data and in numerical models. First, in the TEOS-10 formulation for IAPSO Standard Seawater, the Gibbs function takes the Reference Salinity as its salinity argument, denoted SR, which provides a measure of the mass fraction of dissolved material in solution based on the Reference Composition approximation for Standard Seawater. We discuss uncertainties in both the Reference Composition and the Reference-Composition Salinity Scale on which Reference Salinity is reported. The Reference Composition provides a much-needed fixed benchmark but modified reference states will inevitably be required to improve the representation of Standard Seawater for some studies. However, the Reference-Composition Salinity Scale should remain unaltered to provide a stable representation of salinity for use with the TEOS-10 Gibbs function and in climate change detection studies. Second, when composition anomalies are present in seawater, no single salinity variable can fully represent the influence of dissolved material on the thermodynamic properties of seawater. We consider three distinct representations of salinity that have been used in previous studies and discuss the connections and distinctions between them. One of these variables provides the most accurate representation of density possible as well as improvements over Reference Salinity for the determination of other thermodynamic properties. It is referred to as "Density Salinity" and is represented by the symbol SAdens; it stands out as the most appropriate representation of salinity for use in dynamical physical

    We assessed the effect of an adapted neonatal resuscitation program (NRP) course on healthcare providers' performances in a low-resource setting through the use of video recording. A video recorder, mounted to the radiant warmers in the delivery rooms at Beira Central Hospital, Mozambique, was used to record all resuscitations. One-hundred resuscitations (50 before and 50 after participation in an adapted NRP course) were collected and assessed based on a previously published score. All 100 neonates received initial steps; from these, 77 and 32 needed bag-mask ventilation (BMV) and chest compressions (CC), respectively. There was a significant improvement in resuscitation scores in all levels of resuscitation from before to after the course: for "initial steps", the score increased from 33% (IQR 28-39) to 44% (IQR 39-56), pproviders improved after participation in an adapted NRP course. Video recording was well-accepted by the staff, useful for objective assessment of performance during resuscitation, and can be used as an educational tool in a low-resource setting.

    To evaluate key pre-arrest factors and their collective ability to predict post-cardiopulmonary arrest mortality. CPR is often initiated indiscriminately after in-hospital cardiopulmonary arrest. Improved understanding of pre-arrest factors associated with mortality may inform advance care planning. A cohort of 49,130 adults who experienced pulseless cardiopulmonary arrest from January 2000 to September 2004 was obtained from 366 US hospitals participating in the National Registry for Cardiopulmonary Resuscitation (NRCPR). Logistic regression with bootstrapping was used to model in-hospital mortality, which included those discharged in unfavorable and severely worsened neurologic state (Cerebral Performance Category >/=3). Overall in-hospital mortality was 84.1%. Advanced age, black race, non-cardiac, non-surgical illness category, pre-existing malignancy, acute stroke, trauma, septicemia, hepatic insufficiency, general floor or Emergency Department location, and pre-arrest use of vasopressors or assisted/mechanical ventilation were independently predictive of in-hospital mortality. Retained peri-arrest factors including cardiac monitoring, and shockable initial pulseless rhythms, were strongly associated with survival. The validation model's AUROC curve (0.77) revealed fair performance. Predictive pre-resuscitation factors may supplement patient-specific information available at bedside to assist in revising resuscitation plans during the patient's hospitalization. Copyright 2009.

    Objective Timely identification and prompt resuscitation of newborns in the delivery room may cause a decline in neonatal morbidity and mortality. We try to identify risk factors in mother and fetus that result in birth of newborns needing resuscitation at birth. Methods Case notes of all deliveries and neonates born from April 2010 to March 2011 in Mahdieh Medical Center (Tehran, Iran), a Level III Neonatal Intensive Care Unit, were reviewed; relevant maternal, fetal and perinatal data was extracted and analyzed. Findings During the study period, 4692 neonates were delivered; 4522 (97.7%) did not require respiratory assistance. One-hundred seven (2.3%) newborns needed resuscitation with bag and mask ventilation in the delivery unit, of whom 77 (1.6%) babies responded to bag and mask ventilation while 30 (0.65%) neonates needed endotracheal intubation and 15 (0.3%) were given chest compressions. Epinephrine/volume expander was administered to 10 (0.2%) newborns. In 17 patients resuscitation was continued for >10 mins. There was a positive correlation between the need for resuscitation and following risk factors: low birth weight, preterm labor, chorioamnionitis, pre-eclampsia, prolonged rupture of membranes, abruptio placentae, prolonged labor, meconium staining of amniotic fluid, multiple pregnancy and fetal distress. On multiple regression; low birth weight, meconium stained liquor and chorioamnionitis revealed as independent risk factors that made endotracheal intubation necessary. Conclusion Accurate identification of risk factors and anticipation at the birth of a high-risk neonate would result in adequate preparation and prompt resuscitation of neonates who need some level of intervention and thus, reducing neonatal morbidity and mortality.

    Full Text Available The survival of patients after the sudden circulatory arrest (SCA depends not only on immediate onset of resuscitative measures, but also on their quality.The purpose of the study. The purpose is to assess the compliance of basic and expanded resuscitative measures carried out by healthcare providers in hospitals with modern national and international guidelines within the frames of a stimulation course.Materials and Methods. The research was perfomed in a multifield hospital in Moscow, in 2016. It consisted of two phases. During the first phase, within the frames of a simulation course, providers' skills in the cardiopul monary resuscitation (CPR and chest compression (CC technique mastership were evaluated. During the second stage, their skills in expanded CPR and ability to work as a part of resuscitation teams were assessed. During the simulation, all team activities were recorded (both audio and video; CC parameters were also registered using a CC pressure control sensor (hereinafter referred to as a sensor and audiovisual tips. The European Resuscitation Council Guidelines for Resuscitation 2015 were used as reference criteria. The analysis was performed using the ZOLL RescueNet Code Review® software. A statistical analysis was performed using the Statistica 7.0 software (MannWhitney Utest. The data were presented as a mean, median ± 25—75 percentiles (25—75 IQR, minimum and maximum values. The difference was considered significant at P<0.05.Results. Test results of most healthcare providers were unsatisfactory when the CPR was performed without sensors and audiovisual tips: the percentage of target CCs was not more than 10% in 72% of providers (n=18. When the CPR was performed with sensors and audiovisual tips regulating the CC quality, the percentage of target CCs was 65.7%. i.e. it was significantly higher than that during the CPR without the sensor and the tips (P=0.0000.

    Interruption of chest compressions should be minimized because of its negative effects on survival. This randomized, controlled, cross-over study aimed to analyze the effectiveness of Macintosh, Miller, McCoy and McGrath laryngoscopes during with or without chest compressions in the scope of a simulated cardiopulmonary resuscitation scenario. The time required for successful tracheal intubation, number of attempts, dental trauma severity and the need for optimization manoeuvres were recorded during cardiopulmonary resuscitation with and without chest compressions. The experience with computer games during the last 10 years were asked to the participants and recorded. McCoy laryngoscope yielded the shortest time for successful tracheal intubation both in the presence of and without chest compressions. During the use of McCoy laryngoscopes, fewer tracheal intubation attempts, lower incidence of dental trauma and lower visual analogue scale scores on the ease of intubation were recorded. Participants who are experienced computer game players using Macintosh, McCoy and McGrath achieved successful tracheal intubation in a significantly shorter time during resuscitation without chest compressions. Dental trauma incidence and number of tracheal intubation attempts did not show any significant difference between the four laryngoscopes being related to the rate of playing computer games. McGrath video laryngoscopes do not appear to have advantages over direct laryngoscopes for securing a smooth and successful tracheal intubation during rhythmic chest compressions. We believe that as McCoy laryngoscope provided tracheal intubation in a shorter time and with fewer attempts, this laryngoscope may increase the success rate of resuscitation.

    The majority of acute care facilities have not developed policies or guidelines to facilitate family presence during cardiopulmonary resuscitation. Prior studies have shown that the personal beliefs and attitudes of hospital personnel involved in resuscitation efforts are the primary reasons family presence is not offered. This 2-phase, before/after study was conducted in a 388-bed academic trauma center, and in a 143-bed community hospital in eastern Washington State in 2008. In phase I, a convenience sample of physicians and registered nurses from both facilities were surveyed about their opinions and beliefs regarding family-witnessed resuscitation (FWR). Spearman's rho and independent t-tests were used to compare support of FWR between and within roles and practice location subgroups. In phase II of the study, clinician subgroups in the community hospital were re-surveyed following an educational program that used evidence-based information. Independent t-test and one-way ANOVA were used to compare pre and post-education mean scores of subgroups on indicators of effective teaching strategies and improved FWR support. Opinions on FWR vary within and between practice roles and locations, with the strongest variable of support being prior experience with FWR. Following FWR education, mean scores improved for survey variables chosen as indicators of FWR support and teaching effectiveness. When CPR providers are presented with FWR education, their opinion-based beliefs may be modified, decreasing barriers to family witnessed resuscitation and improving overall support of FWR as an extension of family-centered care.

    Pregnancy-related mortality, estimated to occur in approximately 1: 50,000 deliveries, is rare in developed countries. The 2010 American Heart Association (AHA) Guidelines for Resuscitation emphasize the importance of high-quality chest compression as a key determinant of successful cardiopulmonary resuscitation. During pregnancy, the uterus can compress the inferior vena cava, impeding venous return and thereby reducing stroke volume and cardiac output. To maximize the effectiveness of chest compressions in pregnancy, the AHA guidelines recommend the 27-30 degrees left-lateral tilt (LLT) position. When CPR is performed on parturients in the LLT position, chest compressions will probably be more effective if performed with the operator standing on the left side of the patient. The videolaryngoscope Pentax-AWS Airwayscope (AWS) was found to be an effective tool for airway management during chest compressions in 27 LLT simulations, suggesting that the AWS may be a useful device for airway management during maternal resuscitation.

    Since the 1970s, most of the research and debate regarding interventions for cardiopulmonary arrest have focused on advanced life support (ALS) therapies and early defibrillation strategies. During the past decade, however, international guidelines for cardiopulmonary resuscitation (CPR) have not only emphasized the concept of uninterrupted chest compressions, but also improvements in the timing, rate and quality of those compressions. In essence, it has been a ''revolution'' in resuscitation medicine in terms of ''coming full circle'' to the 1960s when basic CPR was first developed. Recent data have indicated the need for minimally-interrupted chest compressions with an accompanying emphasis toward removing rescue ventilation altogether in sudden cardiac arrest, at least in the few minutes after a sudden unheralded collapse. In other studies, transient delays in defibrillation attempts and ALS interventions are even recommended so that basic CPR can be prioritized to first restore and maintain better coronary artery perfusion. New devices have now been developed to modify, in real-time, the performance of basic CPR, during both training and an actual resuscitative effort. Several new adjuncts have been created to augment chest compressions or enhance venous return and evolving technology may now be able to identify ventricular fibrillation (VF) without interrupting chest compressions. A renewed focus on widespread CPR training for the average person has also returned to center stage with ground-breaking training initiatives including validated video-based adult learning courses that can reliably teach and enable long term retention of basic CPR skills and automated external defibrillator (AED) use.

    Despite advances in the field of intravenous therapy, phlebitis is still a common complication of peripheral venous catheter and finding an appropriate solution to prevent and reduce the incidence of this complication remains challenging. One of the methods used in reducing the incidence of phlebitis is the use of saline lock, which is forgotten in most hospitals. Therefore, this study aimed to evaluate its impact on the incidence and severity of phlebitis. In a single-blind (the researcher) clinical trial, 88 patients with peripheral venous catheter admitted in cardiac care units in selected hospitals of Isfahan University of Medical Sciences, Iran, were selected through convenient sampling method. They were randomly divided into two groups of intervention and control groups using random number table. The intervention group received 3 ml of 0.9% normal saline sterilized before and after each intravenous drug or every 12 h. However, in the control group, the intravenous drugs were given as routine and saline lock was not used. The evaluation of intravenous catheter regarding the incidence of phlebitis and its degrees using Jackson's Visual Infusion Phlebitis Scale was performed 6 times within 72 h (every 12 h). Results were evaluated by SPSS software using descriptive statistics, Chi-square test, t-test, and Mann-Whitney test. Results showed that there was a statistically significant difference between the two groups regarding the degree of phlebitis (P = 0.003). The percentage of phlebitis incidence in the control group was 88.6% and in the intervention group was 43.2%. There was a statistically significant difference between the two groups (P phlebitis in the group without saline lock (control), compared to the intervention group, was 10.3 times greater (CI = 95%). The incidence of phlebitis in both groups increased with increase in the duration of catheter placement. The results of this study showed that the use of saline lock in the intervention group compared

    To evaluate the impact of neonatal resuscitation and basic obstetric care on intrapartum-related neonatal mortality in low and middle-income countries, using the mathematical model, Maternal and Neonatal Directed Assessment of Technology (MANDATE). Using MANDATE, we evaluated the impact of interventions for intrapartum-related events causing birth asphyxia (basic neonatal resuscitation, advanced neonatal care, increasing facility birth, and emergency obstetric care) when implemented in home, clinic, and hospital settings of sub-Saharan African and India for 2008. Total intrapartum-related neonatal mortality (IRNM) was acute neonatal deaths from intrapartum-related events plus late neonatal deaths from ongoing intrapartum-related injury. Introducing basic neonatal resuscitation in all settings had a large impact on decreasing IRNM. Increasing facility births and scaling up emergency obstetric care in clinics and hospitals also had a large impact on decreasing IRNM. Increasing prevalence and utilization of advanced neonatal care in hospital settings had limited impact on IRNM. The greatest improvement in IRNM was seen with widespread advanced neonatal care and basic neonatal resuscitation, scaled-up emergency obstetric care in clinics and hospitals, and increased facility deliveries, resulting in an estimated decrease in IRNM to 2.0 per 1,000 live births in India and 2.5 per 1,000 live births in sub-Saharan Africa. With more deliveries occurring in clinics and hospitals, the scale-up of obstetric care can have a greater effect than if modeled individually. Use of MANDATE enables health leaders to direct resources towards interventions that could prevent intrapartum-related deaths. A lack of widespread implementation of basic neonatal resuscitation, increased facility births, and emergency obstetric care are missed opportunities to save newborn lives.

    To investigate temporal variations in dispatcher-assisted and bystander-initiated resuscitation efforts and their association with survival after bystander-witnessed out-of-hospital cardiac arrests (OHCAs). We retrospectively analyzed the neurologically favorable 1-month survival and the parameters related to dispatcher assisted cardiopulmonary resuscitation (DA-CPR) and bystander CPR (BCPR) for 227,524 OHCA patients between 2007 and 2013 in Japan. DA-CPR sensitivity for OHCAs, bystander's compliance to DA-CPR assessed by the proportion of bystanders who follow DA-CPR, and performance of BCPR measured by the rate of bystander-initiated CPR in patients without DA-CPR were calculated as indices of resuscitation efforts. Performance of BCPR was only similar to temporal variations in the survival (correlation between hourly paired values, R 2 =0.263, P=0.01): a lower survival rate (3.4% vs 4.2%) and performance of BCPR (23.1% vs 30.8%) during night-time (22:00-5:59) than during non-night-time. In subgroup analyses based on interaction tests, all three indices deteriorated during night-time when OHCAs were witnessed by non-family (adjusted odds ratio, 0.73-0.82), particularly in non-elderly patients. The rate of public access defibrillation for these OHCAs markedly decreased during night-time (adjusted odds ratio, 0.49) with delayed emergency calls and BCPR initiation. Multivariable logistic regression analyses revealed that the survival rate of non-family-witnessed OHCAs was 1.83-fold lower during night-time than during non-night-time. Dispatcher-assisted and bystander-initiated resuscitation efforts are low during night-time in OHCAs witnessed by non-family. A divisional alert system to recruit well-trained individuals is needed in order to improve the outcomes of night-time OHCAs witnessed by non-family bystanders. Copyright © 2018 Elsevier Inc.

    Full Text Available Background: Almost half of pediatric third-year residents surveyed in 2000 had never led a resuscitation event. With increasing restrictions on residency work hours and a decline in patient volume in some hospitals, there is potential for fewer opportunities. Purpose: Our primary purpose was to test the hypothesis that an unannounced mock resuscitation in a high-fidelity in-situ simulation training program would improve both residents’ self-confidence and observed performance of adopted best practices in neonatal resuscitation. Methods: Each pediatric and medicine–pediatric resident in one pediatric residency program responded to an unannounced scenario that required resuscitation of the high fidelity infant simulator. Structured debriefing followed in the same setting, and a second cycle of scenario response and debriefing occurred before ending the 1-hour training experience. Measures included pre- and post-program confidence questionnaires and trained observer assessments of live and videotaped performances. Results: Statistically significant pre–post gains for self-confidence were observed for 8 of the 14 NRP critical behaviors (p=0.00–0.03 reflecting knowledge, technical, and non-technical (teamwork skills. The pre–post gain in overall confidence score was statistically significant (p=0.00. With a maximum possible assessment score of 41, the average pre–post gain was 8.28 and statistically significant (p<0.001. Results of the video-based assessments revealed statistically significant performance gains (p<0.0001. Correlation between live and video-based assessments were strong for pre–post training scenario performances (pre: r=0.64, p<0.0001; post: r=0.75, p<0.0001. Conclusions: Results revealed high receptivity to in-situ, simulation-based training and significant positive gains in confidence and observed competency-related abilities. Results support the potential for other applications in residency and continuing education.

    To assess whether advances in neonatal care in the last decade have altered the outcome of very-low-birth-weight (VLBW) infants after cardiopulmonary resuscitation (CPR) in the neonatal intensive care unit (NICU). Medical records of all VLBW infants (n=283, body weight (BW)=1066+/-281 g, gestational age (GA)=28.3+/-2.9 weeks) admitted to the NICU between 1999 and 2002 were reviewed. In all, 29 (10.25%) infants received CPR in the NICU. Only one of these infants survived. After adjusting for GA, the clinical variables significantly associated with the need for CPR in the NICU were (adjusted odds ratio; 95% CI): pulmonary hemorrhage (7.89; 3.06 to 20.28), pulmonary air leak syndrome (23.90; 7.58 to 75.4), and delivery by Cesarian section (0.26; 0.1 to 0.66). The results were similar when the data were reanalyzed matching the 28 infants in the CPR group with 28 infants of identical GA in the non-CPR group. Survival rate for the infants who require CPR in the NICU remains extremely poor. This poor outcome needs to be discussed with parents and the option of the "do not resuscitate" (DNR) order may be appropriate for these infants, especially for those infants with multiple organ failure unresponsive to therapy.

    Effective assessment and resuscitation of trauma patients requires an organised, multidisciplinary team. Literature evaluating leadership roles of nurses in trauma resuscitation and their effect on team performance is scarce. To assess the effect of allocating the most senior nurse as team leader of trauma patient assessment and resuscitation on communication, documentation and perceptions of leadership within an Australian emergency department. The study design was a pre-post-test survey of emergency nursing staff (working at resuscitation room level) perceptions of leadership, communication, and documentation before and after the implementation of a nurse leader role. Patient records were audited focussing on initial resuscitation assessment, treatment, and nursing clinical entry. Descriptive statistical analyses were performed. Communication trended towards improvement. All (100%) respondents post-test stated they had a good to excellent understanding of their role, compared to 93.2% pre-study. A decrease (58.1-12.5%) in 'intimidating personality' as a negative aspect of communication. Nursing leadership had a 6.7% increase in the proportion of those who reported nursing leadership to be good to excellent. Accuracy of clinical documentation improved (P = 0.025). Trauma nurse team leaders improve some aspects of communication and leadership. Development of trauma nurse leaders should be encouraged within trauma team training programmes.

    There are no evidence-based recommendations on the use of different techniques of respiratory support and chest compressions (CC) during neonatal cardiopulmonary resuscitation (CPR). We studied the short-term effects of different ventilatory support strategies along with CC representing clinical practice on gas exchange [arterial oxygen saturation (SaO2), arterial partial pressure of oxygen (PaO2) and arterial partial pressure of carbon dioxide (PaCO2)], hemodynamics and cerebral oxygenation. We hypothesized that in newborn piglets with cardiac arrest, use of a T-piece resuscitator (TPR) providing positive end-expiratory pressure (PEEP) improves gas exchange as measured by SaO2 during CPR as compared to using a self-inflating bag (SIB) without PEEP. Furthermore, we explored the effects of a mechanical ventilator without synchrony to CC. Thirty newborn piglets with asystole were randomized into three groups and resuscitated for 20 min [fraction of inspired oxygen (FiO2) = 0.21 for 10 min and 1.0 thereafter]. Group 1 received ventilation using a TPR [peak inspiratory pressure (PIP)/PEEP of 20/5 cm H2O, rate 30/min] with inflations interposed between CC (3:1 ratio). Group 2 received ventilation using a SIB (PIP of 20 cm H2O without PEEP, rate 30/min) with inflations interposed between CC (3:1 ratio). Group 3 received ventilation using a mechanical ventilator (PIP/PEEP of 20/5 cm H2O, rate 30/min). CC were applied with a rate of 120/min without synchrony to inflations. We found no significant differences in SaO2 between the three groups. However, there was a trend toward a higher SaO2 [TPR: 28.0% (22.3-40.0); SIB: 23.7% (13.4-52.3); ventilator: 44.1% (39.2-54.3); median (interquartile range)] and a lower PaCO2 [TPR: 95.6 mm Hg (82.1-113.6); SIB: 100.8 mm Hg (83.0-108.0); ventilator: 74.1 mm Hg (68.5-83.1); median (interquartile range)] in the mechanical ventilator group. We found no significant effect on gas exchange using different respiratory support strategies

    The use of simulation-based team training in neonatal resuscitation has increased in Sweden during the last decade, but no formal evaluation of this training method has been performed. This study evaluated the effect of simulation-based team training on the self-assessed ability of personnel to perform neonatal resuscitation. We evaluated a full-day simulation-based team training course in neonatal resuscitation, by administering a questionnaire to 110 physicians, nurses and midwives before and after the training period. The questionnaire focused on four important domains: communication, leadership, confidence and technical skills. The study was carried out in Sweden from 2005 to 2007. The response rate was 84%. Improvements in the participants' self-assessed ability to perform neonatal resuscitation were seen in all four domains after training (p technical skills domain compared to experienced personnel (p = 0.001). No differences were seen between professions or time since training in any of the four domains. Personnel with less previous experience with neonatal resuscitation showed improved confidence (p = 0.007) and technical skills (p = 0.003). A full-day course on simulation-based team training with video-supported debriefing improved the participants' self-assessed ability to perform neonatal resuscitation. ©2017 Foundation Acta Paediatrica.

    This places a unique demand on a resuscitator which can be used safely at birth. It must be able to achieve such pressures without injuring the lungs; yet once the FRC has been established, it must be able to adapt itself to the differing ventilatory requirements, without altering the blood chemistry of the neonate.

    There are few data available on the interaction of inflations, chest compressions (CC), and delivery of tidal volumes in newborn infants undergoing resuscitation in the presence of endotracheal tube (ET) leaks. To determine the effects of different respiratory support strategies along with CC on changes in tidal volume and ET leaks in hypoxic newborn piglets with cardiac arrest. Asphyxiated newborn piglets, intubated with weight-adapted uncuffed ET, were randomized into three groups and resuscitated according to ILCOR 2010 guidelines: (1) T-piece resuscitator (TPR) group = peak inspiratory pressure (PIP)/positive end-expiratory pressure (PEEP) 25/5 cm H2O, rate 30/min, inflations interposed between CC (3:1 ratio); (2) self- inflating bag (SIB) group = PIP 25 cm H2O without PEEP, rate 30/min, inflations interposed between CC (3:1 ratio), and (3) ventilator group = PIP/PEEP of 25/5 cm H2O, rate 30/min. CC were applied with a rate of 120/min without synchrony to inflations. We observed a significant increase of leak (average increase 11.4%) when CC was added to respiratory support (p = 0.0001). Expired tidal volume was larger in the SIB group than in the two other modes which both applied PEEP. However, tidal volumes caused by CC only were larger in the two groups with PEEP than in the SIB group (without PEEP). There is interaction between lung inflations and CC affecting leak and delivery of tidal volume, which may be influenced by the mode/device used for respiratory support. Leak is larger in the presence of PEEP. However, CC cause additional tidal volume which is larger in the presence of PEEP. © 2016 S. Karger AG, Basel.

    The pathogenetic mechanisms associated to the beneficial effects of mixed venous oxygen saturation (SvO(2))-guided resuscitation during sepsis are unclear. Our purpose was to evaluate the effects of an algorithm of SvO(2)-driven resuscitation including fluids, norepinephrine and dobutamine on hemodynamics, inflammatory response, and cardiovascular oxidative stress during a clinically resembling experimental model of septic shock. Eighteen anesthetized and catheterized pigs (35-45 kg) were submitted to peritonitis by fecal inoculation (0.75 g/kg). After hypotension, antibiotics were administered, and the animals were randomized to two groups: control (n = 9), with hemodynamic support aiming central venous pressure 8 to 12 mmHg, urinary output 0.5 mL/kg per hour, and mean arterial pressure greater than 65 mmHg; and SvO(2) (n = 9), with the goals above, plus SvO(2) greater than 65%. The interventions lasted 12 h, and lactated Ringer's and norepinephrine (both groups) and dobutamine (SvO(2) group) were administered. Inflammatory response was evaluated by plasma concentration of cytokines, neutrophil CD14 expression, oxidant generation, and apoptosis. Oxidative stress was evaluated by plasma and myocardial nitrate concentrations, myocardial and vascular NADP(H) oxidase activity, myocardial glutathione content, and nitrotyrosine expression. Mixed venous oxygen saturation-driven resuscitation was associated with improved systolic index, oxygen delivery, and diuresis. Sepsis induced in both groups a significant increase on IL-6 concentrations and plasma nitrate concentrations and a persistent decrease in neutrophil CD14 expression. Apoptosis rate and neutrophil oxidant generation were not different between groups. Treatment strategies did not significantly modify oxidative stress parameters. Thus, an approach aiming SvO(2) during sepsis improves hemodynamics, without any significant effect on inflammatory response and oxidative stress. The beneficial effects associated

    Prompt administration of high-quality cardiopulmonary resuscitation (CPR) is a key determinant of survival from cardiac arrest. Strategies to improve CPR quality at point of care could improve resuscitation outcomes. We tested whether a low cost and scalable mobile phone- or smart watch-based solution could provide accurate measures of compression depth and rate during simulated CPR. Fifty health care providers (58% intensive care unit nurses) performed simulated CPR on a calibrated training manikin (Resusci Anne, Laerdal) while wearing both devices. Subjects received real-time audiovisual feedback from each device sequentially. Primary outcome was accuracy of compression depth and rate compared with the calibrated training manikin. Secondary outcome was improvement in CPR quality as defined by meeting both guideline-recommend compression depth (5 to 6 cm) and rate (100 to 120/minute). Compared with the training manikin, typical error for compression depth was mobile device feedback (60% vs 50%; p = 0.3). Sessions that did not meet guideline recommendations failed primarily because of inadequate compression depth (46 ± 2 mm). In conclusion, a mobile device application-guided CPR can accurately track compression depth and rate during simulation in a practice environment in accordance with resuscitation guidelines.

    Full Text Available Abstract Background Junior physicians are sometimes sent in ambulances with critically ill patients who require urgent transfer to another hospital. Unfamiliar surroundings and personnel, time pressure, and lack of experience may imply a risk of insufficient treatment during transportation as this can cause the physician to loose the expected overview of the situation. While health care professionals are expected to follow complex algorithms when resuscitating, stress can compromise both solo-performance and teamwork. Aim To examine whether inter-hospital resuscitation improved with a structured team briefing between physician and ambulance crew in preparation for transfer vs. review of resuscitation guidelines. The effect parameters were physician team leadership (requesting help, delegating tasks, time to resuscitation key elements (chest compressions, defibrillation, ventilations, medication, or a combination of these termed "the first meaningful action", and hands-off ratio. Methods Participants: 46 physicians graduated within 5 years. Design: A simulation intervention study with a control group and two interventions (structured team briefing or review of guidelines.

  4. Absolute Salinity, ''Density Salinity'' and the Reference-Composition Salinity Scale: present and future use in the seawater standard TEOS-10

    Full Text Available Salinity plays a key role in the determination of the thermodynamic properties of seawater and the new TEOS-101 standard provides a consistent and effective approach to dealing with relationships between salinity and these thermodynamic properties. However, there are a number of practical issues that arise in the application of TEOS-10, both in terms of accuracy and scope, including its use in the reduction of field data and in numerical models.

    First, in the TEOS-10 formulation for IAPSO Standard Seawater, the Gibbs function takes the Reference Salinity as its salinity argument, denoted SR, which provides a measure of the mass fraction of dissolved material in solution based on the Reference Composition approximation for Standard Seawater. We discuss uncertainties in both the Reference Composition and the Reference-Composition Salinity Scale on which Reference Salinity is reported. The Reference Composition provides a much-needed fixed benchmark but modified reference states will inevitably be required to improve the representation of Standard Seawater for some studies. However, the Reference-Composition Salinity Scale should remain unaltered to provide a stable representation of salinity for use with the TEOS-10 Gibbs function and in climate change detection studies.

    Second, when composition anomalies are present in seawater, no single salinity variable can fully represent the influence of dissolved material on the thermodynamic properties of seawater. We consider three distinct representations of salinity that have been used in previous studies and discuss the connections and distinctions between them. One of these variables provides the most accurate representation of density possible as well as improvements over Reference Salinity for the determination of other thermodynamic properties. It is referred to as "Density Salinity" and is represented by the symbol

    Cardiopulmonary resuscitation (CPR) has recently been added to the school curriculum worldwide and is currently taught to students between the ages of 10 and 16 years. The effect of the age of trainees on their satisfaction with CPR training has yet been elucidated. The aim of this study was to compare the satisfaction of trainees of different ages who participated in CPR training in schools in Japan. In total, 392 primary school students (10-11 years old), 1798 junior high school students (12-13 years old), and 4162 high schools students (15-16 years old) underwent the same 3-h course of CPR training, according to the guidelines of 2000 for Emergency Cardiovascular Care and CPR. The course was evaluated by a questionnaire completed by the participants. Primary school students responded most positively to all questions, including those reflecting enjoyment and the confidence of participants to apply CPR (Jonckheere-Terpstra test: P CPR training was strongly related to their age. Primary school students enjoyed CPR training more and were more confident in their ability to perform CPR than junior high and high school students were. Therefore, children aged 10-11 years may be the most appropriate candidates for the introduction of CPR training in schools.

    Printing and dyeing wastewater with high content of organic matters, high colority, and poor biochemical performance is hard to be degraded. In this study, we isolated viable but non-culturable (VBNC) bacteria from printing and dyeing wastewater with the culture media contained resuscitation promoting factor (Rpf) protein secreted by Micrococcus luteus, counted the culturable cells number with the most probable number, sequenced 16S rRNA genes, and performed polymerase chain reaction-denaturing gradient gel electrophoresis. It is obviously that the addition of Rpf in the enrichment culture could promote growth and resuscitation of bacteria in VBNC state to obtain more fastidious bacteria significantly. The identified bacteria were assigned to nine genera in the treatment group, while the two strains of Ochrobactrum anthropi and Microbacterium sp. could not be isolated from the control group. The function of isolated strains was explored and these strains could degrade the dye of Congo red. This study provides a new sight into the further study including the present state, composition, formation mechanism, and recovery mechanism about VBNC bacteria in printing and dyeing wastewater, which would promote to understand bacterial community in printing and dyeing wastewater, and to obtain VBNC bacteria from ecological environment.

    In the context of the European Resuscitation Council (ERC) guidelines, modifications of the proposed treatment algorithm need to be performed in order to respond to different parameters. In this respect several factors interacting with cardiac arrest are essential and need to be included in the therapy. This case report demonstrates an example of resuscitation in the situation of hypothermia. After a near drowning accident and approximately 30 min underwater, a patient suffering from severe hypothermia initially required resuscitation after the rescue. A return of spontaneous circulation (ROSC) was successfully achieved within a short length of time and after 15 days on the intensive care unit the patient was discharged to a rehabilitation facility without any signs of focal neurological deficits. Section 8 of the ERC guidelines provides additional information for resuscitation under specific conditions. In this case report, hypothermia was one of the main criteria leading to an adjusted pharmacological therapy. Furthermore, selection of the appropriate hospital for an optimal advanced treatment including controlled warming of the patient and management of hypothermia-induced complications had to be evaluated.

    INTRODUCTION: The International Space Station will need to be as capable as possible in providing Advanced Cardiac Life Support (ACLS) and cardiopulmonary resuscitation (CPR). Previous studies with manikins in parabolic microgravity (0 G) have shown that delivering CPR in microgravity is difficult. End tidal carbon dioxide (PetCO2) has been previously shown to be an effective non-invasive tool for estimating cardiac output during cardiopulmonary resuscitation. Animal models have shown that this diagnostic adjunct can be used as a predictor of survival when PetCO2 values are maintained above 25% of pre-arrest values. METHODS: Eleven anesthetized Yorkshire swine were flown in microgravity during parabolic flight. Physiologic parameters, including PetCO2, were monitored. Standard ACLS protocols were used to resuscitate these models after chemical induction of cardiac arrest. Chest compressions were administered using conventional body positioning with waist restraint and unconventional vertical-inverted body positioning. RESULTS: PetCO2 values were maintained above 25% of both 1-G and O-G pre-arrest values in the microgravity environment (33% +/- 3 and 41 +/- 3). No significant difference between 1-G CPR and O-G CPR was found in these animal models. Effective CPR was delivered in both body positions although conventional body positioning was found to be quickly fatiguing as compared with the vertical-inverted. CONCLUSIONS: Cardiopulmonary resuscitation can be effectively administered in microgravity (0 G). Validation of this model has demonstrated that PetCO2 levels were maintained above a level previously reported to be predictive of survival. The unconventional vertical-inverted position provided effective CPR and was less fatiguing as compared with the conventional body position with waist restraints.

    Full Text Available Background: Severe metabolic acidosis occurs during orthotopic liver transplantation (OLT particularly during the anhepatic phase. Although NaHCO3 is considered as the current standard therapy, there are numerous adverse effects. The aim of this study was to determine whether the restricted use of normal saline during anesthesia could reduce the need for NaHCO3. Methods: In this study we enrolled 75 patients with end-stage liver disease who underwent OLT from February 2010 until September 2010 at the Shiraz Organ Transplantation Center. Fluid management of two different transplant anesthetics were compared. The effect of restricted normal saline fluid was compared with non-restricted normal saline fluid on hemodynamic and acid-base parameters at three times during OLT: after the skin incision (T1, 15 min before reperfusion (T2, and 5 min after reperfusion (T3. Results: There were no significant differences in demographic characteristics of the donors and recipients (P>0.05. In the restricted normal saline group there was significantly lower central venous pressure (CVP than in the non-restricted normal saline group (P=0.002. No significant differences were noted in the other hemodynamic parameters between the two groups (P>0.05. In the non-restricted normal saline group arterial blood pH (P=0.01 and HCO3 (P=0.0001 were significantly less than the restricted normal saline group. The NaHCO3 requirement before reperfusion was significantly more than with the restricted normal saline group (P=0.001. Conclusion: Restricted normal saline administration during OLT reduced the severity of metabolic acidosis and the need for NaHCO3 during the anhepatic phase.

    Full Text Available Hydrocarbons are the principal component of insect cuticle and play an important role in maintaining water balance. Cuticular impermeability could be an adaptative response to salinity and desiccation in aquatic insects; however, cuticular hydrocarbons have been poorly explored in this group and there are no previous data on saline species. We characterized cuticular hydrocarbons of adults and larvae of two saline aquatic beetles, namely Nebrioporus baeticus (Dytiscidae and Enochrus jesusarribasi (Hydrophilidae, using a gas chromatograph coupled to a mass spectrometer. The CHC profile of adults of both species, characterized by a high abundance of branched alkanes and low of unsaturated alkenes, seems to be more similar to that of some terrestrial beetles (e.g., desert Tenebrionidae compared with other aquatic Coleoptera (freshwater Dytiscidae. Adults of E. jesusarribasi had longer chain compounds than N. baeticus, in agreement with their higher resistance to salinity and desiccation. The more permeable cuticle of larvae was characterized by a lower diversity in compounds, shorter carbon chain length and a higher proportion of unsaturated hydrocarbons compared with that of the adults. These results suggest that osmotic stress on aquatic insects could exert a selection pressure on CHC profile similar to aridity in terrestrial species.

  14. High salinity volatile phases in magmatic Ni-Cu-platinum group element deposits

    Hanley, J. J.; Mungall, J. E.

    2004-12-01

    The role of "deuteric" fluids (exsolved magmatic volatile phases) in the development of Ni-Cu-PGE (platinum group element) deposits in mafic-ultramafic igneous systems is poorly understood. Although considerable field evidence demonstrates unambiguously that fluids modified most large primary Ni-Cu-PGE concentrations, models which hypothesize that fluids alone were largely responsible for the economic concentration of the base and precious metals are not widely accepted. Determination of the trace element composition of magmatic volatile phases in such ore-forming systems can offer considerable insight into the origin of potentially mineralizing fluids in such igneous environments. Laser ablation ICP-MS microanalysis allows researchers to confirm the original metal budget of magmatic volatile phases and quantify the behavior of trace ore metals in the fluid phase in the absence of well-constrained theoretical or experimental predictions of ore metal solubility. In this study, we present new evidence from major deposits (Sudbury, Ontario, Canada; Stillwater Complex, Montana, U.S.A.) that compositionally distinct magmatic brines and halide melt phases were exsolved from crystallizing residual silicate melt and trapped within high-T fluid conduits now comprised of evolved rock compositions (albite-quartz graphic granite, orthoclase-quartz granophyre). Petrographic evidence demonstrates that brines and halide melts coexisted with immiscible carbonic phases at the time of entrapment (light aliphatic hydrocarbons, CO2). Brine and halide melt inclusions are rich in Na, Fe, Mn, K, Pb, Zn, Ba, Sr, Al and Cl, and homogenize by either halite dissolution at high T ( ˜450-700° C) or by melting of the salt phase (700-800° C). LA-ICPMS analyses of single inclusions demonstrate that high salinity volatile phases contained abundant base metals (Cu, Fe, Sn, Bi) and precious metals (Pt, Pd, Au, Ag) at the time of entrapment. Notably, precious metal concentrations in the inclusions

    Full Text Available Ischemia-reperfusion injury following cardiopulmonary resuscitation (CPR is associated with a systemic inflammatory response, resulting in post-resuscitation disease. In the present study we investigated the response of the pleiotropic inflammatory cytokine macrophage migration inhibitory factor (MIF to CPR in patients admitted to the hospital after out-of-hospital cardiac arrest (OHCA. To describe the magnitude of MIF release, we compared the blood levels from CPR patients with those obtained in healthy volunteers and with an aged- and gender-matched group of patients undergoing cardiac surgery with the use of extracorporeal circulation.Blood samples of 17 patients with return of spontaneous circulation (ROSC after OHCA were obtained upon admission to the intensive care unit, and 6, 12, 24, 72 and 96 h later. Arrest and treatment related data were documented according to the Utstein style.In patients after ROSC, MIF levels at admission (475.2±157.8 ng/ml were significantly higher than in healthy volunteers (12.5±16.9 ng/ml, p<0.007 and in patients after cardiac surgery (78.2±41.6 ng/ml, p<0.007. Six hours after admission, MIF levels were decreased by more than 50% (150.5±127.2 ng/ml, p<0.007, but were not further reduced in the subsequent time course and remained significantly higher than the values observed during the ICU stay of cardiac surgical patients. In this small group of patients, MIF levels could not discriminate between survivors and non-survivors and were not affected by treatment with mild therapeutic hypothermia.MIF shows a rapid and pronounced increase following CPR, hence allowing a very early assessment of the inflammatory response. Further studies are warranted in larger patient groups to determine the prognostic significance of MIF.ClinicalTrials.gov NCT01412619.

    It is suggested that postinjury pain is difficult to examine; thus, investigators have developed experimental pain models. To minimize pain, cryotherapy (cryo) is applied, but reports on its effectiveness are limited. To investigate a pain model for the anterior knee and examine cryo in reducing the pain. Controlled laboratory study. Therapeutic modality laboratory. 30 physically active healthy male subjects who were free from any lower extremity orthopedic, neurological, cardiovascular, or endocrine pathologies. Perceived pain was measured every minute. Surface temperature was also assessed in the center of the patella and the popliteal fossa. There was a significant interaction between group and time (F68,864 = 3.0, P = .0001). At the first minute, there was no difference in pain between the 3 groups (saline/cryo = 4.80 ± 4.87 mm, saline/sham = 2.80 ± 3.55 mm, no saline/cryo = 4.00 ± 3.33 mm). During the first 5 min, pain increased from 4.80 ± 4.87 to 45.90 ± 21.17 mm in the saline/cryo group and from 2.80 ± 3.55 to 31.10 ± 20.25 mm in the saline/sham group. Pain did not change within the no-saline/cryo group, 4.00 ± 3.33 to 1.70 ± 1.70 mm. Pain for the saline/sham group remained constant for 17 min. Cryo decreased pain for 16 min in the saline/cryo group. There was no difference in preapplication surface temperature between or within each group. No change in temperature occurred within the saline/sham. Cooling and rewarming were similar in both cryo groups. Ambient temperature fluctuated less than 1°C during data collection. Intermittent infusion of sterile 5% hypertonic saline may be a useful experimental pain model in establishing a constant level of pain in a controlled laboratory setting. Cryotherapy decreased the induced anterior knee pain for 16 min.

  20. Interactive effects of chemical and biological controls on food-web composition in saline prairie lakes.

    Cooper, Ryan N; Wissel, Björn

    2012-11-27

    Salinity is restricting habitatability for many biota in prairie lakes due to limited physiological abilities to cope with increasing osmotic stress. Yet, it remains unclear how salinity effects vary among major taxonomic groups and what role other environmental parameters play in shaping food-web composition. To answer these questions, we sampled fish, zooplankton and littoral macroinvertebrates in 20 prairie lakes (Saskatchewan, Canada) characterized by large gradients in water chemistry and lake morphometry. We showed that salinity thresholds differed among major taxonomic groups, as most fishes were absent above salinities of 2 g L-1, while littoral macroinvertebrates were ubiquitous. Zooplankton occurred over the whole salinity range, but changed taxonomic composition as salinity increased. Subsequently, the complexity of fish community (diversity) was associated with large changes in invertebrate communities. The directional changes in invertebrate communities to smaller taxa indicated that complex fish assemblages resulted in higher predation pressure. Most likely, as the complexity of fish community decreased, controls of invertebrate assemblages shifted from predation to competition and ultimately to productivity in hypersaline lakes. Surprisingly, invertebrate predators did not thrive in the absence of fishes in these systems. Furthermore, the here identified salinity threshold for fishes was too low to be a result of osmotic stress. Hence, winterkill was likely an important factor eliminating fishes in low salinity lakes that had high productivity and shallow water depth. Ultimately, while salinity was crucial, intricate combinations of chemical and biological mechanisms also played a major role in controlling the assemblages of major taxonomic groups in prairie lakes.

    Critical appraisal of outcomes after burn shock resuscitation with albumin has previously been restricted to small relatively old randomized trials, some with high risk of bias. Extensive recent data from nonrandomized studies assessing the use of albumin can potentially reduce bias and add precision. The objective of this meta-analysis was to determine the effect of burn shock resuscitation with albumin on mortality and morbidity in adult patients. Randomized and nonrandomized controlled clinical studies evaluating mortality and morbidity in adult patients receiving albumin for burn shock resuscitation were identified by multiple methods, including computer database searches and examination of journal contents and reference lists. Extracted data were quantitatively combined by random-effects meta-analysis. Four randomized and four nonrandomized studies with 688 total adult patients were included. Treatment effects did not differ significantly between the included randomized and nonrandomized studies. Albumin infusion during the first 24 hours showed no significant overall effect on mortality. However, significant statistical heterogeneity was present, which could be abolished by excluding two studies at high risk of bias. After those exclusions, albumin infusion was associated with reduced mortality. The pooled odds ratio was 0.34 with a 95% confidence interval of 0.19 to 0.58 (P Albumin administration was also accompanied by decreased occurrence of compartment syndrome (pooled odds ratio, 0.19; 95% confidence interval, 0.07-0.50; P albumin can improve outcomes of burn shock resuscitation. However, the scope and quality of current evidence are limited, and additional trials are needed.

    Although return of spontaneous circulation (ROSC) is frequently achieved during resuscitation for sudden cardiac arrest, systolic blood pressure can then decrease, requiring additional myocardial support. Previous studies have shown that a series of 1-ms electrical pulses delivered through the defibrillation patches during ventricular fibrillation (VF) can stimulate the autonomic nervous system to increase myocardial function following defibrillation. We hypothesized that a similar series of electrical pulses could increase myocardial function and blood pressure during the early post-resuscitation period. Six swine were studied that underwent 6-7 min. Each animal received 5, 10, 15, or 20 pulse packets consisting of 6 10 A, 1-ms pulses every 3-4 s in random order whenever systolic blood pressure became less than 50 mmHg. All four sets of pulse packets were delivered to each animal. Systolic blood pressure and cardiac function (left ventricular +dP/dt) were increased to pre-stimulation levels or above by all four sets of pulse packets. The increases were significantly greater for the longer than the shorter number of pulse packets. The mean+/-SD duration of the time that the systolic pressure remained above 50 mmHg following pulse delivery was 4.2+/-2.5 min. Electrical stimulation during regular rhythm following prolonged VF and resuscitation can increase blood pressure and cardiac function to above prestimulation levels.

    To assess the feasibility and safety of CT-guided percutaneous transthoracic radiofrequency ablation (RFA) with saline infusion of pulmonary tissue in rabbits. Twenty-eight New Zealand White rabbits were divided into two groups: an RFA group (n=10) and a saline-enhanced RFA (SRFA) group (n=18). In the RFA group, percutaneous RFA of the lung was performed under CT guidance and using a 17-gauge internally cooled electrode. In the SRFA group, 1.5 ml of 0.9% saline was infused slowly through a 21-gauge, polyteflon-coated Chiba needle prior to and during RFA. Lesion size and the healing process were studied in rabbits sacrificed at times from the day following treatment to three weeks after, and any complications were noted. In the SRFA group, the mean diameter (12.5{+-}1.6 mm) of acute RF lesions was greater than that of RFA lesions (8.5{+-}1.4 mm) (p < .05). The complications arising in 12 cases were pneumothorax (n=8), thermal injury to the chest wall (n=2), hemothorax (n=1), and lung abscess (n=1). Although procedure-related complications tended to occur more frequently in the SRFA group (55.6%) than in the RFA group (20%), the difference was not statistically significant (p .11). Saline-enhanced RFA of pulmonary tissue in rabbits produces more extensive coagulation necrosis than conventional RFA procedures, without adding substantial risk of serious complications.

    To determine whether the use of CPRmeter(®) during the resuscitation manoeuvres, is related to a higher quality of external cardiac massage, as recommended by the International Liaison Committee on Resuscitation (ILCOR). To compare the quality obtained without the use or this, and whether there are differences related to anthropometric, demographic, professional and/or occupational factors. Experimental, open trial performed with life support simulators in a stratified random sample of 88 health workers randomly distributed between groups A (without indications of the device) and B (with them). The homogeneity of their confounding variables was compared, as well as the compressions depth and compressions rate, the proportion of completed release, and distribution of the quality massage variable (according to criteria ILCOR) between the groups. The qualitative variables were analysed with the chi-square test, and quantitative variables with the Student t-test or Mann-Whitney U-test and the association between the variable quality massage variable, and use of the device with the odds ratio. Group A: mean depth 42.1mm (standard deviation 10.1), mean rate 121.3/min (21.6), percentage of complete release 71.2% (36.9). Group B: 51.2mm (5.9) 111.9/min (6.4), 92.9% (10.1) respectively. Odds ratio for quality massage regarding the use of the device was 5.170 (95% CI; 2.060-12.977). The use of CPRmeter(®) device in simulated resuscitations is related to a higher quality of cardiac massage, improving the approach to the ILCOR recommendations, regardless of the characteristics of the participants. They were 83.8% more likely to achieve a quality massage using the device than without it. Copyright © 2015 Elsevier España, S.L.U. y SEEIUC. All rights reserved.

    Cardiac arrest induces whole-body ischemia, which causes damage to multiple organs. Understanding how each organ responds to ischemia/reperfusion is important to develop better resuscitation strategies. Because direct measurement of organ function is not practicable in most animal models, we attempt to use mitochondrial respiration to test efficacy of resuscitation on the brain, heart, kidney, and liver following prolonged cardiac arrest. Male Sprague-Dawley rats are subjected to asphyxia-induced cardiac arrest for 30 min or 45 min, or 30 min cardiac arrest followed by 60 min cardiopulmonary bypass resuscitation. Mitochondria are isolated from brain, heart, kidney, and liver tissues and examined for respiration activity. Following cardiac arrest, a time-dependent decrease in state-3 respiration is observed in mitochondria from all four tissues. Following 60 min resuscitation, the respiration activity of brain mitochondria varies greatly in different animals. The activity after resuscitation remains the same in heart mitochondria and significantly increases in kidney and liver mitochondria. The result shows that inhibition of state-3 respiration is a good marker to evaluate the efficacy of resuscitation for each organ. The resulting state-3 respiration of brain and heart mitochondria following resuscitation reenforces the need for developing better strategies to resuscitate these critical organs following prolonged cardiac arrest.

    Aggressive large volume resuscitation is obligatory to achieve necessary tissue oxygenation. An adequate venous preload normalizes global hemodynamics and avoids multiorgan failure (MOF) and death in patients with multiple injuries. Large volume resuscitation is associated with complications in minimally monitored patients. A properly guided resuscitation procedure will finally prevent MOF and patient death. Transpulmonary thermodilution technique and gastric tonometry are used in venous prel...

    Only a small fraction of bacteria can autonomously initiate growth on agar plates. Nongrowing bacteria typically enter a metabolically inactive dormant state and require specific chemical trigger factors or signals to exit this state and to resume growth. Micrococcus luteus has become a model organism for this important yet poorly understood phenomenon. Only a few resuscitation signals have been described to date, and all of them are produced endogenously by bacterial species. We report the discovery of a novel type of resuscitation signal that allows M. luteus to grow on agar but not agarose plates. Fractionation of the agar polysaccharide complex and sulfation of agarose allowed us to identify the signal as highly sulfated saccharides found in agar or carrageenans. Purification of hydrolyzed κ-carrageenan ultimately led to the identification of the signal as a small fragment of a large linear polysaccharide, i.e., an oligosaccharide of five or more sugars with a repeating disaccharide motif containing d-galactose-4-sulfate (G4S) 1,4-linked to 3,6-anhydro-α-d-galactose (DA), G4S-(DA-G4S) n ≥2 IMPORTANCE Most environmental bacteria cannot initiate growth on agar plates, but they can flourish on the same plates once growth is initiated. While there are a number of names for and manifestations of this phenomenon, the underlying cause appears to be the requirement for a molecular signal indicating safe growing conditions. Micrococcus luteus has become a model organism for studying this growth initiation process, often called resuscitation, because of its apparent connection with the persistent or dormant form of Mycobacterium tuberculosis , an important human pathogen. In this report, we identify a highly sulfated saccharide from agar or carrageenans that robustly resuscitates dormant M. luteus on agarose plates. We identified and characterized the signal as a small repeating disaccharide motif. Our results indicate that signals inherent in or absent from the

    To develop a reliable and validated tool to evaluate technical resuscitation skills in a pediatric simulation setting. Four Resuscitation and Emergency Simulation Checklist for Assessment in Pediatrics (RESCAPE) evaluation tools were created, following international guidelines: intraosseous needle insertion, bag mask ventilation, endotracheal intubation, and cardiac massage. We applied a modified Delphi methodology evaluation to binary rating items. Reliability was assessed comparing the ratings of 2 observers (1 in real time and 1 after a video-recorded review). The tools were assessed for content, construct, and criterion validity, and for sensitivity to change. Inter-rater reliability, evaluated with Cohen kappa coefficients, was perfect or near-perfect (>0.8) for 92.5% of items and each Cronbach alpha coefficient was ≥0.91. Principal component analyses showed that all 4 tools were unidimensional. Significant increases in median scores with increasing levels of medical expertise were demonstrated for RESCAPE-intraosseous needle insertion (P = .0002), RESCAPE-bag mask ventilation (P = .0002), RESCAPE-endotracheal intubation (P = .0001), and RESCAPE-cardiac massage (P = .0037). Significantly increased median scores over time were also demonstrated during a simulation-based educational program. RESCAPE tools are reliable and validated tools for the evaluation of technical resuscitation skills in pediatric settings during simulation-based educational programs. They might also be used for medical practice performance evaluations. Copyright © 2017 Elsevier Inc. All rights reserved.

    It is possible that the exportation of North American and European models has hindered the creation of a structured cardiopulmonary resuscitation (CPR) training programme in developing countries. The objective of this paper is to describe the design and present the results of a European paediatric and neonatal CPR training programme adapted to Honduras. A paediatric CPR training project was set up in Honduras with the instructional and scientific support of the Spanish Group for Paediatric and Neonatal CPR. The programme was divided into four phases: CPR training and preparation of instructors; training for instructors; supervised teaching; and independent teaching. During the first phase, 24 Honduran doctors from paediatric intensive care, paediatric emergency and anaesthesiology departments attended the paediatric CPR course and 16 of them the course for preparation as instructors. The Honduran Paediatric and Neonatal CPR Group was formed. In the second phase, workshops were given by Honduran instructors and four of them attended a CPR course in Spain as trainee instructors. In the third phase, a CPR course was given in Honduras by the Honduran instructors, supervised by the Spanish team. In the final phase of independent teaching, eight courses were given, providing 177 students with training in CPR. The training of independent paediatric CPR groups with the collaboration and scientific assessment of an expert group could be a suitable model on which to base paediatric CPR training in Latin American developing countries.

    A favorable neurological outcome is likely to be achieved in out-of-hospital cardiac arrest (OHCA) patients with ventricular fibrillation or pulseless ventricular tachycardia (VF/VT) on the initial electrocardiogram (ECG). However, in patients without pre-hospital restoration of spontaneous circulation despite the initial VF/VT, the outcome is extremely low by conventional cardiopulmonary resuscitation (CPR). Extracorporeal CPR (ECPR) may enhance cerebral blood flow and recovery of neurological function. We prospectively examined how ECPR for OHCA with VF/VT would affect neurological outcomes. The design of this trial was a prospective, observational study. We compared differences of outcome at 1 and 6 months after OHCA between ECPR group (26 hospitals) and non-ECPR group (20 hospitals). Primary endpoints were the rate of favorable outcomes defined by the Glasgow-Pittsburgh Cerebral Performance and Overall Performance Categories (CPC) 1 or 2 at 1 and 6 months after OHCA. Based on intention-to-treat analysis, CPC 1 or 2 were 12.3% (32/260) in the ECPR group and 1.5% (3/194) in the non-ECPR group at 1 month (P<0.0001), and 11.2% (29/260) and 2.6% (5/194) at 6 months (P=0.001), respectively. By per protocol analysis, CPC 1 or 2 were 13.7% (32/234) in the ECPR group and 1.9% (3/159) in the non-ECPR group at 1 month (P<0.0001), and 12.4% (29/234) and 3.1% (5/159) at 6 months (P=0.002), respectively. In OHCA patients with VF/VT on the initial ECG, a treatment bundle including ECPR, therapeutic hypothermia and IABP was associated with improved neurological outcome at 1 and 6 months after OHCA.

    Introduction The objective is to describe the implementation and outcomes of a structured communication module used to supplement case-based simulated resuscitation training in an emergency medicine (EM) clerkship. Methods We supplemented two case-based simulated resuscitation scenarios (cardiac arrest and blunt trauma) with role-play in order to teach medical students how to deliver news of death and poor prognosis to family of the critically ill or injured simulated patient. Quantitative outcomes were assessed with pre and post-clerkship surveys. Secondarily, students completed a written self-reflection (things that went well and why; things that did not go well and why) to further explore learner experiences with communication around resuscitation. Qualitative analysis identified themes from written self-reflections. Results A total of 120 medical students completed the pre and post-clerkship surveys. Majority of respondents reported that they had witnessed or role-played the delivery of difficult news, but only few had real-life experience of delivering news of death (20/120, 17%) and poor prognosis (34/120, 29%). This communication module led to statistically significant increased scores for comfort, confidence, and knowledge with communicating difficult news of death and poor prognosis. Pre-post scores increased for those agreeing with statements (somewhat/very much) for delivery of news of poor prognosis: comfort 69% to 81%, confidence 66% to 81% and knowledge 76% to 90% as well as for statements regarding delivery of news of death: comfort 52% to 68%, confidence 57% to 76% and knowledge 76% to 90%. Respondents report that patient resuscitations (simulated and/or real) generated a variety of strong emotional responses such as anxiety, stress, grief and feelings of loss and failure. Conclusion A structured communication module supplements simulated resuscitation training in an EM clerkship and leads to a self-reported increase in knowledge, comfort, and

    To determine the response of Litopenaeus vannamei to periodical salinity fluctuation, a 30-day experiment was conducted in laboratory. In this experiment, two salinity fluctuation amplitudes of 4 (group S4) and 10 (group S10) were designed. The constant salinity of 30 (group S0) was used as the control. Levels of shrimp growth, molting frequency (MF), cellular energy status (ATP, ADP and AMP), as well as the expression of genes encoding molt-inhibiting hormone (MIH), crustacean hyperglycemic hormone (CHH), ecdysteroid-regulated protein (ERP), and energy-related AMP-activated protein kinase (AMPK) were determined. The results showed that periodical salinity fluctuation significantly influenced all indicators except MF which ranged from 13.3% in group S10 to15.4% in group S4. In comparison with shrimps cultured at the constant salinity of 30, those in group S4 showed a significant elevation in growth rate, food conversion efficiency, cellular energy status, ERP and MIH gene transcript abundance, and a significant reduction in CHH and AMPK transcript abundance ( P MIH and CHH gene expression when compared to the control ( P < 0.05). According to our findings, L. vannamei may be highly capable of tolerating salinity fluctuation. When ambient salinity fluctuated at approx. 4, the increased MF and energy stores in organisms may aid to promoting shrimp growth.

  17. Long-Term Stored Hemoglobin-Vesicles, a Cellular Type of Hemoglobin-Based Oxygen Carrier, Has Resuscitative Effects Comparable to That for Fresh Red Blood Cells in a Rat Model with Massive Hemorrhage without Post-Transfusion Lung Injury.

    Masahiro Tokuno

    Full Text Available Hemoglobin-vesicles (HbV, encapsulating highly concentrated human hemoglobin in liposomes, were developed as a substitute for red blood cells (RBC and their safety and efficacy in transfusion therapy has been confirmed in previous studies. Although HbV suspensions are structurally and physicochemically stabile for least 1-year at room temperature, based on in vitro experiments, the issue of whether the use of long-term stored HbV after a massive hemorrhage can be effective in resuscitations without adverse, post-transfusion effects remains to be clarified. We report herein on a comparison of the systemic response and the induction of organ injuries in hemorrhagic shock model rats resuscitated using 1-year-stored HbV, freshly packed RBC (PRBC-0 and by 28-day-stored packed RBC (PRBC-28. The six-hour mortality after resuscitation was not significantly different among the groups. Arterial blood pressure and blood gas parameters revealed that, using HbV, recovery from the shock state was comparable to that when PRBC-0 was used. Although no significant change was observed in serum parameters reflecting liver and kidney injuries at 6 hours after resuscitation among the three resuscitation groups, results based on Evans Blue and protein leakage in bronchoalveolar lavage fluid, the lung wet/dry weight ratio and histopathological findings indicated that HbV as well as PRBC-0 was less predisposed to result in a post-transfusion lung injury than PRBC-28, as evidenced by low levels of myeloperoxidase accumulation and subsequent oxidative damage in the lung. The findings reported herein indicate that 1-year-stored HbV can effectively function as a resuscitative fluid without the induction of post-transfused lung injury and that it is comparable to fresh PRBC, suggesting that HbV is a promising RBC substitute with a long shelf-life.

    Crew Resource Management (CRM) is a team-building communication process first implemented in the aviation industry to improve safety. It has been used in health care, particularly in surgical and intensive care settings, to improve team dynamics and reduce errors. We adapted a CRM process for implementation in the trauma resuscitation area. An interdisciplinary steering committee developed our CRM process to include a didactic classroom program based on a preimplementation survey of our trauma team members. Implementation with new cultural and process expectations followed. The Human Factors Attitude Survey and Communication and Teamwork Skills assessment tool were used to design, evaluate, and validate our CRM program. The initial trauma communication survey was completed by 160 team members (49% response). Twenty-five trauma resuscitations were observed and scored using Communication and Teamwork Skills. Areas of concern were identified and 324 staff completed our 3-hour CRM course during a 3-month period. After CRM training, 132 communication surveys and 38 Communication and Teamwork Skills observations were completed. In the post-CRM survey, respondents indicated improvement in accuracy of field to medical command information (p = 0.029); accuracy of emergency department medical command information to the resuscitation area (p = 0.002); and team leader identity, communication of plan, and role assignment (p = 0.001). After CRM training, staff were more likely to speak up when patient safety was a concern (p = 0.002). Crew Resource Management in the trauma resuscitation area enhances team dynamics, communication, and, ostensibly, patient safety. Philosophy and culture of CRM should be compulsory components of trauma programs and in resuscitation of injured patients. Copyright © 2014 American College of Surgeons. Published by Elsevier Inc.

    Yunye Ning

    Full Text Available BACKGROUND: Over-production of mucus is an important pathophysiological feature in chronic airway disease such as chronic obstructive pulmonary disease (COPD and asthma. Cigarette smoking (CS is the leading cause of COPD. Oxidative stress plays a key role in CS-induced airway abnormal mucus production. Hydrogen protected cells and tissues against oxidative damage by scavenging hydroxyl radicals. In the present study we investigated the effect of hydrogen on CS-induced mucus production in rats. METHODS: Male Sprague-Dawley rats were divided into four groups: sham control, CS group, hydrogen-rich saline pretreatment group and hydrogen-rich saline control group. Lung morphology and tissue biochemical changes were determined by immunohistochemistry, Alcian Blue/periodic acid-Schiff staining, TUNEL, western blot and realtime RT-PCR. RESULTS: Hydrogen-rich saline pretreatment attenuated CS-induced mucus accumulation in the bronchiolar lumen, goblet cell hyperplasia, muc5ac over-expression and abnormal cell apoptosis in the airway epithelium as well as malondialdehyde increase in the BALF. The phosphorylation of EGFR at Tyr1068 and Nrf2 up-regulation expression in the rat lungs challenged by CS exposure were also abrogated by hydrogen-rich saline. CONCLUSION: Hydrogen-rich saline pretreatment ameliorated CS-induced airway mucus production and airway epithelium damage in rats. The protective role of hydrogen on CS-exposed rat lungs was achieved at least partly by its free radical scavenging ability. This is the first report to demonstrate that intraperitoneal administration of hydrogen-rich saline protected rat airways against CS damage and it could be promising in treating abnormal airway mucus production in COPD.

    2004-09-01

    Recent studies have associated interruptions of cardiopulmonary resuscitation imposed by automated external defibrillators (AEDs) with poor resuscitation outcome. In particular, the "hands-off" interval between precordial compressions and subsequent defibrillation shock has been implicated. We sought to determine the range of variation among current-generation AEDs with respect to this characteristic. Seven AEDs from six manufacturers were characterized via stopwatch and arrhythmia simulator with respect to the imposed hands-off interval. All AEDs were equipped with new batteries, and measurements were repeated five times for each AED. A wide variation in the hands-off interval between precordial compressions and shock delivery was observed, ranging from 5.2 to 28.4 secs, with only one AED achieving an interruption of <10 secs. Laboratory and clinical data suggest that this range of variation could be responsible for a more than two-fold variation in patient resuscitation success, an effect that far exceeds any defibrillation efficacy differences that may hypothetically exist. In addition to defibrillation waveform and dose, researchers should consider the hands-off cardiopulmonary resuscitation interruption interval between cardiopulmonary resuscitation and subsequent defibrillation shock to be an important covariate of outcome in resuscitation studies. Defibrillator design should minimize this interval to avoid potential adverse consequences on patient survival.

    The authors compared the performance of a group of anesthesia providers to closed-loop (Learning Intravenous Resuscitator [LIR]) management in a simulated hemorrhage scenario using cardiac output monitoring. A prospective cohort study. In silico simulation. University hospital anesthesiologists and the LIR closed-loop fluid administration system. Using a patient simulator, a 90-minute simulated hemorrhage protocol was run, which included a 1,200-mL blood loss over 30 minutes. Twenty practicing anesthesiology providers were asked to manage this scenario by providing fluids and vasopressor medication at their discretion. The simulation program was also run 20 times with the LIR closed-loop algorithm managing fluids and an additional 20 times with no intervention. Simulated patient weight, height, heart rate, mean arterial pressure, and cardiac output (CO) were similar at baseline. The mean stroke volume, the mean arterial pressure, CO, and the final CO were higher in the closed-loop group than in the practitioners group, and the coefficient of variance was lower. The closed-loop group received slightly more fluid (2.1 v 1.9 L, p closed-loop maintained more stable hemodynamics than the practitioners primarily because the fluid was given earlier in the protocol and CO optimized before the hemorrhage began, whereas practitioners tended to resuscitate well but only after significant hemodynamic change indicated the need. Overall, these data support the potential usefulness of this closed-loop algorithm in clinical settings in which dynamic predictors are not available or applicable. Published by Elsevier Inc.

    Schoolteachers are expected to play a role in teaching cardiopulmonary resuscitation (CPR) to schoolchildren, but little is known about their attitudes, actual knowledge and willingness to do so. We conducted a survey about CPR knowledge, preparedness to perform and teach CPR as well as attitude towards an alternative self-learning strategy amongst Flemish teachers. A questionnaire was developed consisting of four distinct parts: (1) Demographics; (2) CPR knowledge and skills level; (3) Attitude towards training and (4) Resuscitation experience. Content experts screened the questionnaire in view of content validity. One hundred and seventy-one students in Educational Sciences were each asked to interview 25 different teachers. A total of 4273 teachers participated in the study (primary school n=856; secondary school n=2562; higher education n=855). Of all respondents, 59% (2539/4273) had received previous CPR training with the highest proportion observed in primary schoolteachers (69%) and in the age group 21-30 years (68%). Mandatory CPR training at school was supported by 41% (1751/4273) of the teachers and only 36% was aware that CPR is now formally included in the secondary education curriculum. Sixty-one percent (2621/4273) did not feel capable and was not willing to teach CPR, mainly because of a perceived lack of knowledge in 50% (2151/2621). In addition 69% (2927/4273) felt incompetent to perform correct CPR and 73% (3137/4273) wished more training. Feeling incompetent and not willing to teach was related to the absence of previous training. Primary schoolteachers and the age group 21-30 years were most willing to teach CPR. Although many teachers mentioned previous CPR training, only a minority of mostly young and primary schoolteachers felt competent in CPR and was willing to teach it to their students.

    Full Text Available Thyroid hormones (T3, T4 have marked effect on body metabolism and in controlling osmoregulation activity in fish. The aim of this study was to determine the effect of water salinity changes on thyroid hormones level and thyroid-stimulating hormone (TSH of grass carp. For this purpose 120 grass carp were divided randomly in to four groups (10 fish in each group and three replicates per treatment. Three groups were held in three different salinities at concentrations of 4, 8 and 12 g L-1. The fourth group was reared in fresh water and considered as control. After three weeks blood samples were collected from the caudal peduncle vein. Then serum was separated and serum thyroid hormones and TSH were measured by LISA on Microwell plates. Our results indicated that the average of T3 levels in 4, 8 and 12 g L-1 groups were 0.43 ± 0.11, 0.22 ± 0.04 and 0.21 ± 0.04 μg dL-1, respectively. T3 levels in all experimental groups were significantly lower than those of control group (p 0.05. The level of TSH in salinities of 4 and 8 g L-1 groups was significantly higher than that of control group (p < 0.05. The results showed that increasing water salinity can have significant effect on thyroid activity by decreasing T3 and increasing T4 level in serum of grass carp in experimental condition.

Safety index (SI; ratio of CD50C compared with 2-fold median effective dose needed to produce sensory blockade of the 4 drugs was calculated. Isobolograms were used for drug interaction analysis. Second, rats received 1.2-fold CD50A in the 4 groups. When asystole occurred, standard cardiopulmonary resuscitation was started and continued for 30 min or until return of spontaneous circulation (ROSC with native rate–pressure product ≥30% baseline for 5 min.Results: Ranking of CD50C was Levo-BUP < QX-314 ≈ QX-OH. Ranking of CD50A was Levo-BUP < QX-314 < QX-OH. However, the SI of Levo-BUP was significantly higher than that of QX-314 (10.60 vs. 1.20 or QX-OH (10.60 vs. 1.44. The SI of LL-1 was similar to that of Levo-BUP. Nonsynergistic interaction was observed for cardiac effects between QX-OH and Levo-BUP. ROSC was attained initially by 8 of 8 rats in the Levo-BUP group, 3 of 8 in the QX-314 group, 6 of 8 in the QX-OH group, and 8 of 8 in the LL-1 group. Sustained recovery was achieved in the Levo-BUP group but not in the other groups.Conclusion: Levo-BUP and LL-1 are safer than QX-314 or QX-OH. Cardiac effects between QX-OH and Levo-BUP were nonsynergistic. Initial successful resuscitation could be

    To compare the effect of local injection therapy with absolute ethanol and hot-saline in the normal liver of rat. An experimental study was performed with the normal liver of 52 rats. The resected livers were pathologically analyzed on three days, one week, two weeks, and four weeks after injection of 0.1 ml absolute ethanol and hot-saline. The assessment was done in view of 1) main pathologic changes on time, 2) pattern of inflammatory cell infiltration, 3) measurement of necrotic area, 4) effect on vascular and biliary tracts adjacent to necrotic area, and 5) extrahepatic peritoneal adhesion. The main pathologic changes were acute necrosis with inflammation for three days group and secondary regenerative fibrosis in all groups. The degree of necrosis was significantly more severe in absolute ethanol injection group, demonstrating larger necrotic area, than hot-saline injection group. The effect on vessels and bile ducts adjacent to the necrotic area was almost not seen in both groups. The extrahepatic peritoneal adhesion was noted in both groups, but the degree was more prominent in the absolute ethanol injection group than hot-saline injection group. Absolute ethanol is superior to hot-saline in the necrotic effect of percutaneous injection therapy. However, hot-saline could be applied in case of the borderline area between mass and adjacent normal liver or the subcapsular mass

    The lungs of newborns are especially prone to oxidative damage induced by both reactive oxygen and reactive nitrogen species. Yet, these infants are often 1) exposed to high oxygen concentrations, 2) have infections or inflammation, 3) have reduced antioxidant defense, and 4) have high free iron levels which enhance toxic radical generation. Oxidative stress has been postulated to be implicated in several newborn conditions with the phrase "oxygen radical diseases of neonatology" having been coined. There is, however, reason to believe that oxidative stress is increased more when resuscitation is performed with pure oxygen compared with ambient air and that the most effective ventilatory strategy is the avoidance of mechanical ventilation with the use of nasopharyngeal continuous positive airway pressure whenever possible. Multiple ventilation strategies have been attempted to reduce injury and improve outcomes in newborn infants. In this review, the authors summarise the scientific evidence concerning oxidative stress as it relates to resuscitation in the delivery room and to the various modalities of ventilation.

    Full Text Available Introduction. The incidence of sudden cardiac death in patients with severe symptomatic aortic stenosis is up to 34% and resuscitation is described as highly unsuccessful. Case report. A 72-year-old female patient with severe aortic stenosis combined with severe mitral regurgitation and three-vessel coronary artery disease was successfully resuscitated following two in-hospital cardiac arrests. The first cardiac arrest occurred immediately after intraarterial injection of low osmolar iodinated agent during coronary angiography. Angiography revealed 90% occlusion of the proximal left main coronary artery and circumflex branch. The second arrest followed induction of anesthesia. Following successful open-chest resuscitation, aortic valve replacement, mitral valvuloplasty and three-vessel aortocoronary bypass were performed. Postoperative pericardial tamponade required surgical revision. The patient recovered completely. Conclusion. Decision to start resuscitation may be justified in selected patients with critical aortic stenosis, even though cardiopulmonary resuscitation in such cases is generally considered futile.

    To evaluate the effects of structured triglycerides in parenteral nutrition versus a physical medium-chain triglycerides (MCT)/long-chain triglycerides (LCT) mixture on severe hemorrhagic shock patients after resuscitation. In a randomized trial, we studied 20 critical patients with a total blood loss of over 3000 ml perioperatively and/or intraoperatively. The use of triglycerides started from Day 3 postoperation and parenteral nutrition lasted for no less than 5 days. They were allocated to receive one of two nutrition regiments: structured triglycerides in Group A (n = 10) and MCT/LCT in Group B (n = 10). There were no significant differences of general conditions in two groups. Before the start of parenteral nutrition (d0), d1 d3 and d5 after start of infusion, the following parameters were measured: hemoglobin (Hb), platelet count (Plt), alanine aminotransferase (ALT), total bilirubin (TB), direct bilirubin (DB), serum triglycerides (TG), prealbumin (PA) and transferrin (TF). And mean artery pressure (MAP), heart rate (HR) and central vein pressure (CVP) were also recorded at the same time-points. Then the post-TG changes of the above data were compared in both groups. After the use of triglycerides, there were no significant differences of MAP, HR, CVP, Hb and Plt in both groups (P > 0.05). At D3 and D5, the serum levels of TG ((2.1 ± 0.4) vs (1.6 ± 0.6) mg/L, (2.3 ± 0.7) vs (1.5 ± 0.3) mg/L) and alanine aminotransferase ((133 ± 58) vs (97 ± 26) U/L; (116 ± 48) vs (77 ± 31) U/L) were significantly higher in Group B versus those receiving structured triglycerides in Group A (P 0.05). The serum levels of such nutrition markers as PA ((195 ± 55) vs (166 ± 55) mg/L,(245 ± 53) vs (195 ± 58) mg/L) and TF ((2.6 ± 0.5) vs (2.5 ± 0.6) g/L, (3.3 ± 0.8) vs (2.9 ± 0.6) g/L)were significantly higher in Group A than those in Group B (P synthesis and hepatocyte protection, structured triglycerides in parenteral nutrition is advantageous to standard MCT

    The American Heart Association (AHA) guidelines for cardiopulmonary resuscitation (CPR) are nowadays recognized as the world's most authoritative resuscitation guidelines. Adherence to these guidelines optimizes the management of critically ill patients and increases their chances of survival after cardiac arrest. Despite their availability, suboptimal quality of CPR is still common. Currently, the median hospital survival rate after pediatric in-hospital cardiac arrest is 36%, whereas it falls below 10% for out-of-hospital cardiac arrest. Among emerging information technologies and devices able to support caregivers during resuscitation and increase adherence to AHA guidelines, augmented reality (AR) glasses have not yet been assessed. In order to assess their potential, we adapted AHA Pediatric Advanced Life Support (PALS) guidelines for AR glasses. The study aimed to determine whether adapting AHA guidelines for AR glasses increased adherence by reducing deviation and time to initiation of critical life-saving maneuvers during pediatric CPR when compared with the use of PALS pocket reference cards. We conducted a randomized controlled trial with two parallel groups of voluntary pediatric residents, comparing AR glasses to PALS pocket reference cards during a simulation-based pediatric cardiac arrest scenario-pulseless ventricular tachycardia (pVT). The primary outcome was the elapsed time in seconds in each allocation group, from onset of pVT to the first defibrillation attempt. Secondary outcomes were time elapsed to (1) initiation of chest compression, (2) subsequent defibrillation attempts, and (3) administration of drugs, as well as the time intervals between defibrillation attempts and drug doses, shock doses, and number of shocks. All these outcomes were assessed for deviation from AHA guidelines. Twenty residents were randomized into 2 groups. Time to first defibrillation attempt (mean: 146 s) and adherence to AHA guidelines in terms of time to other

    Current cardiopulmonary resuscitation (CPR) guidelines do not define the optimal type of CPR (chest compression-only CPR [CCCPR] or conventional CPR with rescue breathing [CCRB]) to be performed by bystanders when they witness someone collapse. Using a nationwide database of 1.17 million patients who underwent out-of-hospital cardiac arrest (OHCA) in Japan, we enrolled consecutive bystander-witnessed OHCAs of medical origin with resuscitation attempts from January 2005 through December 2014. Multivariable logistic regression analysis was used to assess the association between the type of bystander CPR and the OHCA outcome after one-to-one propensity score matching for CCCPR versus CCRB. The primary outcome measure was one-month survival with a favorable neurological outcome, defined as a cerebral performance category of 1 or 2. Among 143,500 eligible patients with bystander-witnessed OHCAs receiving bystander-initiated CPR, 71.4% received CCCPR and 28.6% received CCRB. In the univariate analysis, the proportion of one-month survival cases with favorable neurological outcome was lower in the CCCPR group than the CCRB group (5.6% [5749/102,487] vs. 6.5% [2682/41,013], odds ratio [OR]; 0.85 [95% confidence interval {CI}; 0.81-0.89]). However, in the multivariate analysis, the CCCPR group showed a more favorable neurological outcome than the CCRB group (adjusted OR 1.12, 95% CI; 1.06-1.19). In the propensity-matched cohort, the CCCPR group also showed a more favorable neurological outcome than the CCRB group (7.2% [2894/40,096] vs. 6.5% [2610/40,096], adjusted OR 1.14, 95% CI; 1.09-1.22). CCCPR is an acceptable resuscitation technique for lay-rescuers responding to bystander witnessed OHCA of presumed medical origin. Copyright © 2018 Elsevier B.V. All rights reserved.

    Full Text Available BACKGROUND: Mild therapeutic hypothermia following cardiac arrest is neuroprotective, but its effect on myocardial dysfunction that is a critical issue following resuscitation is not clear. This study sought to examine whether hypothermia and the combination of hypothermia and pharmacological postconditioning are cardioprotective in a model of cardiopulmonary resuscitation following acute myocardial ischemia. METHODOLOGY/PRINCIPAL FINDINGS: Thirty pigs (28-34 kg were subjected to cardiac arrest following left anterior descending coronary artery ischemia. After 7 minutes of ventricular fibrillation and 2 minutes of basic life support, advanced cardiac life support was started according to the current AHA guidelines. After successful return of spontaneous circulation (n = 21, coronary perfusion was reestablished after 60 minutes of occlusion, and animals were randomized to either normothermia at 38 degrees C, hypothermia at 33 degrees C or hypothermia at 33 degrees C combined with sevoflurane (each group n = 7 for 24 hours. The effects on cardiac damage especially on inflammation, apoptosis, and remodeling were studied using cellular and molecular approaches. Five animals were sham operated. Animals treated with hypothermia had lower troponin T levels (p<0.01, reduced infarct size (34+/-7 versus 57+/-12%; p<0.05 and improved left ventricular function compared to normothermia (p<0.05. Hypothermia was associated with a reduction in: (i immune cell infiltration, (ii apoptosis, (iii IL-1beta and IL-6 mRNA up-regulation, and (iv IL-1beta protein expression (p<0.05. Moreover, decreased matrix metalloproteinase-9 activity was detected in the ischemic myocardium after treatment with mild hypothermia. Sevoflurane conferred additional protective effects although statistic significance was not reached. CONCLUSIONS/SIGNIFICANCE: Hypothermia reduced myocardial damage and dysfunction after cardiopulmonary resuscitation possible via a reduced rate of apoptosis

    This study correlated the effect of witnessing a cardiac arrest and instituting bystander CPR (ByCPR), as a secondary end point in a study evaluating the effect of bicarbonate on survival. This prospective, randomised, double blinded clinical intervention trial enrolled 874 prehospital cardiopulmonary arrest patients encountered in a prehospital urban, suburban, and rural regional emergency medical service (EMS) area. This group underwent conventional advanced cardiac life support intervention followed by empiric early administration of sodium bicarbonate (1 mEq/l), monitoring conventional resuscitation parameters. Survival was measured as presence of vital signs on emergency department (ED) arrival. Data were analysed using chi(2) with Pearson correlation and odds ratio where appropriate. The overall survival rate was 13.9% (110 of 792) of prehospital cardiac arrest patients. The mean (SD) time until provision of bystander cardiopulmonary resuscitation (ByCPR) by laymen was 2.08 (2.77) minutes, and basic life support (BLS) by emergency medical technicians was 6.62 (5.73) minutes. There was improved survival noted with witnessed cardiac arrest-a 2.2-fold increase in survival, 18.9% (76 of 402) versus 8.6% (27 of 315) compared with unwitnessed arrests (ptwo minutes (p = 0.3752). Survival after prehospital cardiac arrest is more likely when witnessed, but not necessarily when ByCPR was performed by laymen.

    The American Heart Association, along with the International Liaison Committee on Resuscitation, recently made changes to the paediatric resuscitation guidelines. Knowledge translation (KT) is imperative, but there is a lack of sufficient evidence for appropriate methodologies for implementation of these guidelines. Paediatric resuscitation presents many challenges; cases happen infrequently, affording few opportunities for implementation of the new guidelines, and are highly stressful and filled with uncertainty. Some KT strategies have shown some success in causing a notable degree of change in behaviour, but none have shown a striking difference when used alone. Previous efforts to disseminate current guidelines centred on development of courses for health care providers and preparing paediatric residents and paediatricians for circumstances they could encounter with paediatric acute illness. None of the studies assessing these techniques measured direct patient outcomes, and only a few demonstrated some long-term knowledge acquisition among trainees. The purpose of the present review was to illuminate the challenges, offer future directions for KT and outline potentially more effective methodologies and strategies to overcome current barriers.

    Cardiopulmonary resuscitation (CPR) is relatively novel branch of medical science, however first descriptions of mouth-to-mouth ventilation are to be found in the Bible and literature is full of descriptions of different resuscitation methods - from flagellation and ventilation with bellows through hanging the victims upside down and compressing the chest in order to stimulate ventilation to rectal fumigation with tobacco smoke. The modern history of CPR starts with Kouwenhoven et al. who in 1960 published a paper regarding heart massage through chest compressions. Shortly after that in 1961Peter Safar presented a paradigm promoting opening the airway, performing rescue breaths and chest compressions. First CPR guidelines were published in 1966. Since that time guidelines were modified and improved numerously by two leading world expert organizations ERC (European Resuscitation Council) and AHA (American Heart Association) and published in a new version every 5 years. Currently 2010 guidelines should be obliged. In this paper authors made an attempt to present history of development of resuscitation techniques and methods and assess the influence of previous lifesaving methods on nowadays technologies, equipment and guidelines which allow to help those women and men whose life is in danger due to sudden cardiac arrest. © 2015 MEDPRESS.

    This study aimed to investigate cardiopulmonary resuscitation (CPR) guideline implementation and CPR training in hospitals. This nationwide study included mandatory resuscitation protocols from each Danish hospital. Protocols were systematically reviewed for adherence to the European Resuscitation Council (ERC) 2010 guidelines and CPR training in each hospital. Data were included from 45 of 47 hospitals. Adherence to the ERC basic life support (BLS) algorithm was 49%, whereas 63 and 58% of hospitals adhered to the recommended chest compression depth and rate. Adherence to the ERC advanced life support (ALS) algorithm was 81%. Hospital BLS course duration was [median (interquartile range)] 2.3 (1.5-2.5) h, whereas ALS course duration was 4.0 (2.5-8.0) h. Implementation of ERC 2010 guidelines on BLS is limited in Danish hospitals 2 years after guideline publication, whereas the majority of hospitals adhere to the ALS algorithm. CPR training differs among hospitals.

    Severe trauma, hemorrhage, and resuscitation can lead to a trauma-related acute lung injury that involves rapid infiltration of immune cells and platelets. This infiltration involves exymatic degradation of matrix proteins, including plasmin, and causes loss of barrier function. Since tranexamic acid (TXA) inhibits plasminogen/ plasmin binding to target substrates, it may attenuate loss of barrier function after severe trauma, hemorrhage, and resuscitation. Sprague-Dawley rats were subjected to polytrauma (laparotomy, and trauma to intestines, liver, right leg skeletal muscle, and right femur fracture), then bled 40% of their blood volume. One hour after completion of polytrauma and hemorrhage, resuscitation was begun with fresh whole blood (FWB) or FWB with prior bolus administration of TXA (10 mg/kg in 0.2 mL). Polytrauma, hemorrhage, and resuscitation with FWB led to an elevation in lung water content that was significantly reduced with TXA administration. Polytrauma and hemorrhage led to rise in the number of neutrophils/monocytes and platelets in the lungs, and a rise in myeloperoxidase (MPO), neutrophil elastase and complement C5a content. While resuscitation with FWB significantly reduced the cellular infiltrate and MPO, FWB/TXA further reduced the levels of neutrophil/monocytes, neutrophil elastase, and complement C5a. Polytrauma and hemorrhage led to rise in lung plasmin activity that was significantly reduced with either FWB or FWB/TXA resuscitation. Severe trauma and hemorrhage leads to increases in lung water content, and immune cell, platelets, MPO, elastase, and C5a content in lung tissue, all markers of inflammation and acute lung injury. The addition of TXA to FWB resuscitation markedly attenuated the rise in these parameters suggesting its utility in treating acute lung injury.

This study determined rates of survival from Code Blue events and the role of opioids and other factors on survival.Methods: Data derived from medical records and the Code Blue and Pharmacy databases were analyzed for factors affecting survival.Results: During 2006, rates of survival from the code only and to discharge were 25.9% and 26.4%, respectively, for Code Blue events involving cardiopulmonary resuscitation (CPR; N = 216. Survival rates for events not ultimately requiring CPR (N = 77 were higher, with 32.5% surviving the code only and 62.3% surviving to discharge. For CPR events, rates of survival to discharge correlated inversely with time to chest compressions and defibrillation, precipitating event, need for airway management, location and age. Time of week, witnessing, postoperative status, gender and opioid use did not influence survival rates. For non-CPR events, opioid use was associated with decreased survival. Survival rates were lowest for patients receiving continuous infusions (P < 0.01 or iv boluses of opioids (P < 0.05.Conclusions: One-quarter of patients survive to discharge after a CPR Code Blue event and two-thirds survive to discharge after a non-CPR event.

    This study aimed to investigate the spoilage capability of Lactobacillus lindneri during the induction and resuscitation of viable but nonculturable (VBNC) state. L. lindneri strain was identified by sequencing the PCR product (amplifying 16S rRNA gene) using ABI Prism 377 DNA Sequencer. During the VBNC state induction by low temperature storage and beer adaption, total, culturable, and viable cells were assessed by acridine orange direct counting, plate counting, and Live/Dead BacLight bacterial viability kit, respectively. Organic acids and diacetyl concentration were measured by reversed-phase high performance liquid chromatography and head dpace gas chromatography, respectively. VBNC state of L. lindneri was successfully induced by both beer adaption and low temperature storage, and glycerol frozen stock was the optimal way to maintain the VBNC state. Addition of catalase was found to be an effective method for the resuscitation of VBNC L. lindneri cells. Furthermore, spoilage capability remained similar during the induction and resuscitation of VBNC L. lindneri. This is the first report of induction by low temperature storage and resuscitation of VBNC L. lindneri strain, as well as the first identification of spoilage capability of VBNC and resuscitated L. lindneri cells. This study indicated that the potential colonization of L. lindneri strain in brewery environment, formation and resuscitation of VBNC state, as well as maintenance in beer spoilage capability, may be an important risk factor for brewery environment.

    Project Strengthening Emergency Medicine, Investing in Learners in Latin America (SEMILLA) created a novel, language and resource appropriate course for the resuscitation of cardiac arrest for Nicaraguan resident physicians. We hypothesized that participation in the Project SEMILLA resuscitation program would significantly improve the physician's management of simulated code scenarios. Thirteen Nicaraguan resident physicians were evaluated while managing simulated cardiac arrest scenarios before, immediately, and at 6 months after participating in the Project SEMILLA resuscitation program. This project was completed in 2014 in Leon, Nicaragua. The Cardiac Arrest Simulation Test (CASTest), a validated scoring system, was used to evaluate performance on a standardized simulated cardiac arrest scenario. Mixed effect logistic regression models were constructed to assess outcomes. On the pre-course simulation exam, only 7.7% of subjects passed the test. Immediately post-course, the subjects achieved a 30.8% pass rate and at 6 months after the course, the pass rate was 46.2%. Compared with pre-test scores, the odds of passing the CASTest at 6 months after the course were 21.7 times higher (95% CI 4.2 to 112.8, PSEMILLA resuscitation course and retain these skills.

    The fibrin-derived peptide Bβ15-42 (FX06) has been proven to attenuate ischemia/reperfusion injury. We tested the hypothesis that Bβ15-42 improves survival rate and neurocognitive recovery after cardiopulmonary resuscitation. Pig and mouse model of cardiopulmonary resuscitation. Two university hospitals. Pigs and mice. Pigs (n = 16) were subjected to 8-minute cardiac arrest. Successful resuscitated pigs (n = 12) were randomized either to 3 mg/kg Bβ15-42 followed by a continuous infusion of 1 mg/kg/hr for 5 hours (pFX06; n = 6) or the control group (pCONTROL; n = 6). Cardiac damage, function, and hemodynamics were recorded up to 8 hours. Mice (n = 52) were subjected to 4-minute cardiac arrest followed by cardiopulmonary resuscitation, and randomized either to two boli of 2.4 mg/kg Bβ15-42 (mFX06; n = 26) or the control group (mCONTROL; n = 26). Fourteen-day survival rate, neurocognitive function, and endothelial integrity (additional experiment with n = 26 mice) were evaluated. Bβ15-42 reduced cumulative fluid intake (3,500 [2,600-4,200] vs 6,800 [5,700-7,400] mL; p = 0.004) within 8 hours in pigs. In mice, Bβ15-42 improved 14-day survival rate (mFX06 vs mCONTROL; 11/26 vs 6/26; p Water-Maze test (15/26 vs 9/26 mice with competence to perform test; p < 0.05). Bβ15-42-treated mice showed a significant higher length of intact pulmonary endothelium and reduced pulmonary leukocyte infiltration. This study confirms the new concept of an important role of fibrin derivatives in global ischemia/reperfusion injury, which can be attenuated by the fibrin-derived peptide Bβ15-42.

    There are few reports of the effectiveness or satisfaction with simulation to learn cardiac surgical resuscitation skills. To test the effect of simulation on the self-confidence of nurses to perform cardiac surgical resuscitation simulation and nurses' satisfaction with the simulation experience. A convenience sample of sixty nurses rated their self-confidence to perform cardiac surgical resuscitation skills before and after two simulations. Simulation performance was assessed. Subjects completed the Satisfaction with Simulation Experience scale and demographics. Self-confidence scores to perform all cardiac surgical skills as measured by paired t-tests were significantly increased after the simulation (d=-0.50 to 1.78). Self-confidence and cardiac surgical work experience were not correlated with time to performance. Total satisfaction scores were high (mean 80.2, SD 1.06) indicating satisfaction with the simulation. There was no correlation of the satisfaction scores with cardiac surgical work experience (τ=-0.05, ns). Self-confidence scores to perform cardiac surgical resuscitation procedures were higher after the simulation. Nurses were highly satisfied with the simulation experience.

    Although most modern dolomites occur in hypersaline environments, the effects of elevated salinity on the microbial mediation of dolomite precipitation have not been fully evaluated. Here we report results of dolomite precipitation in association with a batch culture of Haloferax volcanii DS52, a halophilic archaeon, under various salinities (from 120‰ to 360‰) and the impact of salinity on microbe-mediated dolomite formation. The mineral phases, morphology and atomic arrangement of the precipitates were analyzed by XRD, SEM and TEM, respectively. The amount of amino acids on the archaeal cell surface was quantified by HPLC/MS. The XRD analysis indicated that disordered dolomite formed successfully with the facilitation of cells harvested from cultures with relatively high salinities (200‰ and 280‰) but was not observed in association with cells harvested from cultures with lower salinity (120‰) or the lysates of cells harvested from extremely high salinity (360‰). The TEM analysis demonstrated that the crystals from cultures with a salinity of 200‰ closely matched that of dolomite. Importantly, we found that more carboxyl groups were presented on the cell surface under high salinity conditions to resist the high osmotic pressure, which may result in the subsequent promotion of dolomite formation. Our finding suggests a link between variations in the hydro-chemical conditions and the formation of dolomite via microbial metabolic activity and enhances our understanding about the mechanism of microbially mediated dolomite formation under high salinity conditions.

    To promote the technical training and scientific popularization of cardiopulmonary resuscitation (CPR) in China, the Cardiopulmonary Resuscitation Specialized Committee of Chinese Research Hospital Association combined with the Science Popularization Branch of the Chinese Medical Association wrote "2018 National consensus on cardiopulmonary resuscitation training in China". The formation was based on the general outline about "2016 National consensus on cardiopulmonary resuscitation in China", and to implement the important strategies included the "three pre" policy, prevention, precognition, and pre-warning, before the cardiac arrest (CA); the "three modernization" methods, standardized, diversified and individualized, during the CA; and the "three life" strategies, the rebirth, the extra and the extended, after the CA; and also combined with the concrete National conditions and clinical practice of China area. The document summarized the evidence of published science about CPR training till now, and recommend the establishment of "the CPR Training Triangle" according to the Chinese National conditions. The bases of the triangle were system, training and person, the core of which was CPR science. The main contents were: (1) The "three training" policy for CPR training: the cultivation of a sound system, which included professional credibility, extensive mobilization and continuous driving force, and the participation of the whole people and continuous improvement; the cultivation of scientific guidelines, which included scientific content, methods and thinking; and the cultivation of a healthy culture, which included the enhancement of civic quality, education of rescue scientifically, and advocate of healthy life. (2) The "three training" program of CPR training: training professional skills, which included standard, multiple, and individual skills; training multidimensional, which included time, space, and human; and training flexible, including problem, time

    Education of schoolchildren in cardiopulmonary resuscitation (CPR) is a strategic goal for improvement of bystander CPR in society. The primary objective was to analyse the impact of CPR training on the resuscitation knowledge and self-confidence of secondary schoolchildren. In addition, independent predictors of improved CPR knowledge and self-confidence were investigated. Prospective, randomised-interventional controlled study. Four secondary schools in Germany. Four hundred and twenty-four schoolchildren aged from 14 to 18 years were included into the study. Fifty-one percent were female, and 33% had an immigrant background. The intervention group received a 90-min CPR training session, whereas controls had no intervention. Levels of knowledge and self-confidence in initiating CPR were analysed by a study questionnaire before (t0), 90 min after (t1) and 6 months after training (t2). Based on the evaluation of study questionnaires, the primary endpoint was to determine the development of resuscitation knowledge and self-confidence in initiating cardiopulmonary resuscitation at survey time-points t0, t1 and t2. Schoolchildren in the intervention group (n=207) showed a significantly higher level of knowledge (P CPR training improves the level of knowledge and self-confidence in 14 to 18-year-old schoolchildren. Older schoolchildren are more likely to have increased self-confidence with respect to initiating CPR. Schoolchildren with an immigrant background showed a significantly lower increase in their level of knowledge and self-confidence compared with native children. Adaptation and simplification of teaching materials and further research on educational methods for CPR are urgently needed to enable a sustainable approach to teaching CPR, which also produces a long-lasting effect in the entire population.

    Recently, sustained inflations (SI) during chest compression (CC) (CC+SI) have been suggested as an alternative to the current approach during neonatal resuscitation. No previous study compared CC+SI using CC rates of 90/min to the current 3:1 compression:ventilation ratio (C:V). To determine whether CC+SI versus a 3:1 C:V reduces the time to the return of spontaneous circulation (ROSC) and improves hemodynamic recovery in newborn piglets with asphyxia-induced bradycardia. Term newborn piglets were anesthetized, intubated, instrumented, and exposed to 45-min normocapnic hypoxia followed by asphyxia. Cardiopulmonary resuscitation (CPR) was initiated when the heart rate decreased to 25% of baseline. Piglets were randomized into 3 groups: CC during SI at a rate of 90 CC/min (SI+CC 90, n = 8), a 3:1 C:V using 90 CC and 30 inflations (3:1, n = 8), or a sham group (n = 6). Cardiac function, carotid blood flow, cerebral oxygenation, and respiratory parameters were continuously recorded throughout the experiment. CC+SI significantly reduced the median (IQR) time of ROSC, i.e., 34 s (28-156 s) versus 210 s (72-300 s) in the 3:1 group (p = 0.048). CC+SI also significantly reduced the requirement for 100% oxygen, improved respiratory parameters, and resulted in a similar hemodynamic recovery. CC+SI during CPR significantly improved ROSC in a porcine model of neonatal resuscitation. This is of considerable clinical relevance because improved respiratory and hemodynamic parameters potentially minimize morbidity and mortality in newborn infants. © 2017 S. Karger AG, Basel.

    Objective: The purpose of this study was to compare the enhancement degree of abdomen organs and vessels after different amount of contrast medium using saline flush in abdomen MDCT scanning, which aimed to not affect contrast enhancement, decreased the amount of contrast medium, and reduced the side-effect. Methods: This study group consisted of 75 patients who were referred for contrast enhanced abdominal MDCT for various reasons. Patients were allocated into three groups: injection of 100ml of contrast medium only (A group), injection of 80ml pushed with 20ml of saline solution (B group), and injection of 70ml pushed with 30ml of saline solution (C group). Attenuation values were measured from the liver, spleen, pancreas, kidney, aorta, portal vein, and inferior vena cava in 33 second and 80 second of imaging after injection contrast medium. Results: The portal venous phases of the spleen, pancreas, kidney, aorta, portal vein had statistically significant difference among groups A, B and C. Post hoc test showed statistically significant difference between A group and C group, But no statistically significant difference during the portal venous phases of the pancreas and the kidney between A group and B group. Conclusion: Using a saline flush technique after the injection contrast medium in abdominal MDCT reduced waste of contrast medium and decrease in nephrotoxicity, at the same time, it would not lose important diagnostic information and saved patients cost for the contrast medium.

    Full Text Available Introduction: Lack of water and deterioration in the quality of soil and water resources are considered to be the prime cause of reduced crop yield in arid and semi-arid regions ‘More crop per drop’ by trickle irrigation, deficit irrigation, and uncommon water are the best strategies for mitigating water crises. Different irrigation management strategies are needed to increase production in different areas. In areas where sufficient water is available, a full irrigation strategy could be a suitable option, while in areas where water is limited, deficit irrigation would be an appropriate method, and finally in areas where water resources are saline, management strategies for achieving sustainable production as well as economic yields would be suitable. Maize is the third most important grain crop in the world following wheat and rice and it is the main source of nutrition for humans and animals. Because of the importance of maize in the world, increasing maize production under environmental stresses is a big challenge for agricultural scientists. Different methods of irrigation and the use of saline water that had satisfactory results for increasing agricultural production have been studied by several investigators . The main objective of this study was to establish an efficient use of limited water resources as well as to explore the possibility of replacing saline water with fresh water using different management techniques. Materials and Methods: A field experiment was conducted over two maize cropping seasons (2012–2013 in northern Iran (Gorgan Agricultural Research Station to compare different alternate irrigation scenarios using saline water on corn yield, salinity and soil moisture distribution in a randomized complete block design with three replications. Treatments were: T1 and T2 = 100 and 50 % of crop water requirement with non-saline water, respectively; T3 and T4 = variable and fixed full irrigation with saline and non-saline

    Hemorrhagic shock (HS) due to trauma remains a major cause of morbidity and mortality in the United States, despite continuing progression of advanced life support and treatment. Trauma is the third most common cause of death worldwide and is the leading cause of death in the 1- to 44-year-old age group. Hemorrhagic shock often progresses to multiple organ failure despite conventional resuscitation (CR) that restores central hemodynamics. To examine whether MC-2 would bind glycosaminoglycans to decrease proinflammatory cytokines' influence in the liver, minimize organ edema, prevent liver injury, and improve hepatic perfusion. MC-2, a synthetic octapeptide derived from the heparin-binding domain of murine interferon gamma (IFN-γ), binds glycosaminoglycans to modulate serum and interstitial cytokine levels and activity. A controlled laboratory study of 3y male Sprague-Dawley rats that were randomized to 4 groups of 8 each: sham, sham+MC-2 (50 mg/kg), HS/CR, or HS/CR+MC-2 (HS = 40% of baseline mean arterial pressure for 60 minutes; CR = return of shed blood and 2 volumes of saline). The study began in March, 2013. Effective hepatic blood flow (EHBF) by galactose clearance, wet-dry weights, cytokines, histopathology, complete metabolic panel, and complete blood cell count were performed at 4 hours after CR. MC-2 partially reversed the HS/CR-induced hepatic hypoperfusion at 3 and 4 hours postresuscitation compared with HS/CR alone. Effective hepatic blood flow decreased during the HS period from a mean (SD) of 7.4 (0.3) mL/min/100 g and 7.5 (0.5) mL/min/100g at baseline to 3.7 (0.4) mL/min/100g and 5.9 (0.5) mL/min/100g for the HS/CR and HS/CR+MC-2 groups, respectively (P hepatic blood flow remained constant in the sham groups throughout the experimental protocol. Organ edema was increased in the ileum and liver in the HS/CR vs sham group, and MC-2 decreased edema in the ileum vs the HS/CR group. MC-2 in HS also decreased levels of alanine aminotransferase

    To express Micrococcus luteus resuscitation promoting factor (Rpf) domain and its mutants in prokaryotic cells, and to investigate their bioactivity. The gene of Rpf domain and its mutants (E54K, E54A) were amplified by polymerase chain reaction (PCR) from the genome of Micrococcus luteus and cloned into pMD18-T vector. After sequenced, the Rpf domain and its mutant gene were subcloned into expression vector PGEX-4T-1, and transfected into E. coli DH5alpha. The expressed product was purified by affinity chromatography using GST Fusion Protein Purification bead. The aim proteins were identified by SDS-PAGE analysis and by Western blot with monoclonal antibodies against Rpf domain (mAb). The bioactivity of the proteins was analyzed by stimulating the resuscitation of Mycobacterium smegmatis. The sequences of the PCR products were identical to those of the Rpf domain and its mutant gene in GenBank. The relative molecular mass identified by SDS-PAGE analysis was consistent with that had been reported, which was also confirmed by Western blot analysis that there were specific bindings at 32 000 with Rpf domain mAb. The purified GST-Rpf domain could stimulate resuscitation of Mycobacterium smegmatis. Replacements E54A and especially E54K resulted in inhibition of Rpf resuscitation activity. Rpf domain and two kinds of its mutant protein were obtained, and its effects on the resuscitation of dormant Mycobacterium smegmatis were clarified.

    Full Text Available Aim. To evaluate the effects of erythropoietin administration on the adrenal glands in a swine model of ventricular fibrillation and resuscitation. Methods. Ventricular fibrillation was induced via pacing wire forwarded into the right ventricle in 20 female Landrace/Large White pigs, allocated into 2 groups: experimental group treated with bolus dose of erythropoietin (EPO and control group which received normal saline. Cardiopulmonary resuscitation (CPR was performed immediately after drug administration as per the 2010 European Resuscitation Council (ERC guidelines for Advanced Life Support (ALS until return of spontaneous circulation (ROSC or death. Animals who achieved ROSC were monitored, mechanically ventilated, extubated, observed, and euthanized. At necroscopy, adrenal glands samples were formalin-fixed, paraffin-embedded, and routinely processed. Sections were stained with hematoxylin-eosin. Results. Oedema and apoptosis were the most frequent histological changes and were detected in all animals in the adrenal cortex and in the medulla. Mild and focal endothelial lesions were also detected. A marked interindividual variability in the degree of the intensity of apoptosis and oedema at cortical and medullary level was observed within groups. Comparing the two groups, higher levels of pathological changes were detected in the control group. No significant difference between the two groups was observed regarding the endothelial changes. Conclusions. In animals exposed to ventricular fibrillation, EPO treatment has protective effects on the adrenal gland.
