    The modern treatment of cardiac arrest is an increasingly complex medical procedure with a rapidly changing array of therapeutic approaches designed to restore life to victims of sudden death. The 2 primary goals of providing artificial circulation and defibrillation to halt ventricular fibrillation remain of paramount importance for saving lives. They have undergone significant improvements in technology and dissemination into the community subsequent to their establishment 60 years ago. The evolution of artificial circulation includes efforts to optimize manual cardiopulmonary resuscitation, external mechanical cardiopulmonary resuscitation devices designed to augment circulation, and may soon advance further into the rapid deployment of specially designed internal emergency cardiopulmonary bypass devices. The development of defibrillation technologies has progressed from bulky internal defibrillators paddles applied directly to the heart, to manually controlled external defibrillators, to automatic external defibrillators that can now be obtained over-the-counter for widespread use in the community or home. But the modern treatment of cardiac arrest now involves more than merely providing circulation and defibrillation. As suggested by a 3-phase model of treatment, newer approaches targeting patients who have had a more prolonged cardiac arrest include treatment of the metabolic phase of cardiac arrest with therapeutic hypothermia, agents to treat or prevent reperfusion injury, new strategies specifically focused on pulseless electric activity, which is the presenting rhythm in at least one third of cardiac arrests, and aggressive post resuscitation care. There are discoveries at the cellular and molecular level about ischemia and reperfusion pathobiology that may be translated into future new therapies. On the near horizon is the combination of advanced cardiopulmonary bypass plus a cocktail of multiple agents targeted at restoration of normal metabolism and

    Objective:To investigate application of cardiopulmonary resuscitation(CPR) measures within the golden minutes inEurope.Methods:The material was taken from theUniversityClinical Center ofKosovo -EmergencyCentre inPristina, during the two(2) year period(2010-2011).The collected date belong to the patients with cardiac arrest have been recorded in the patients' log book protocol at the emergency clinic.Results:During the2010 to2011 in the emergency center of theCUCK inPristina have been treated a total of269 patients with cardiac arrest, of whom159 or59.1% have been treated in2010, and110 patients or40.9% in2011.Of the269 patients treated in the emergency centre,93 or34.6% have exited lethally in the emergency centre, and176 or 65.4% have been transferred to other clinics.In the total number of patients with cardiac arrest, males have dominated with186 cases, or69.1%.The average age of patients included in the survey was56.7 year oldSD±16.0 years.Of the269 patients with cardiac arrest, defibrillation has been applied for93 or34.6% of patients.In the outpatient settings defibrillation has been applied for3 or3.2% of patients.Patients were defibrillated with application of one to four shocks. Of27 cases with who have survived cardiac arrest, none of them have suffered cardiac arrest at home,3 or11.1% of them have suffered cardiac arrest on the street, and24 or88.9% of them have suffered cardiac arrest in the hospital.5 out of27 patients survived have ended with neurological impairment.Cardiac arrest cases were present during all days of the week, but frequently most reported cases have been onMonday with32.0% of cases, and onFriday with24.5% of cases. Conclusions:All survivors from cardiac arrest have received appropriate medical assistance within10 min from attack, which implies that if cardiac arrest occurs near an institution health care(with an opportunity to provide the emergent health care) the rate of survival is higher.

    The survival of traumatic cardiac arrest patients poses a challenge for Emergency Medical Services initiating advanced life support on-scene, especially with regard to having to decide immediately whether to initiate prehospital emergency thoracotomy. Although the necessity for carrying out the procedure remains a cause for debate, it can be life-saving when performed with the correct indications and approaches. PMID:26816077

    Enhanced measures for resuscitation of adults are based on basic measures of resuscitation. The central elements are highly effective chest compressions and avoidance of disruptions that are associated with poor patient outcomes that occur within seconds. The universal algorithm distinguishes the therapy for ventricular fibrillation from the therapy in asystole or pulseless electrical activity (PEA) by the need of defibrillation, and amiodarone administration in the former. Defibrillation is biphasic. In all other aspects, there are no differences in therapy. In each episode of cardiac arrest, reversible causes should be excluded or treated. For the diagnosis during resuscitation, sonography can be helpful. What is new in the 2015 ERC recommendations is the use of capnography, which can be used for the assessment of ROSC (return of spontaneous circulation), ventilation, resuscitation and intubation quality. Mechanical resuscitation devices can be used in selected situations. Successful primary resuscitation should be directly followed by measures of the post-resuscitation care. PMID:27022698

    Full Text Available Background: Guidelines on performing cardiopulmonary resuscitation (CPR have been published from time to time, and formal training programs are conducted based on these guidelines. Very few data are available in world literature highlighting the impact of these trainings on CPR outcome. Aim: The aim of our study was to evaluate the impact of the American Heart Association (AHA-certified basic life support (BLS and advanced cardiac life support (ACLS provider course on the outcomes of CPR in our hospital. Materials and Methods : An AHA-certified BLS and ACLS provider training programme was conducted in our hospital in the first week of October 2009, in which all doctors in the code blue team and intensive care units were given training. The retrospective study was performed over an 18-month period. All in-hospital adult cardiac arrest victims in the pre-BLS/ACLS training period (January 2009 to September 2009 and the post-BLS/ACLS training period (October 2009 to June 2010 were included in the study. We compared the outcomes of CPR between these two study periods. Results: There were a total of 627 in-hospital cardiac arrests, 284 during the pre-BLS/ACLS training period and 343 during the post-BLS/ACLS training period. In the pre-BLS/ACLS training period, 52 patients (18.3% had return of spontaneous circulation, compared with 97 patients (28.3% in the post-BLS/ACLS training period (P < 0.005. Survival to hospital discharge was also significantly higher in the post-BLS/ACLS training period (67 patients, 69.1% than in the pre-BLS/ACLS training period (12 patients, 23.1% (P < 0.0001. Conclusion : Formal certified BLS and ACLS training of healthcare professionals leads to definitive improvement in the outcome of CPR.

    Full Text Available Introduction: The American Heart Association (AHA recommends regionalized care following out-of-hospital cardiac arrest (OHCA at cardiac resuscitation centers (CRCs. Key level 1 CRC criteria include 24/7 percutaneous coronary intervention (PCI capability, therapeutic hypothermia capability, and annual volume of ≥40 patients resuscitated from OHCA. Our objective was to characterize the availability and utilization of resources relevant to post-cardiac arrest care, including level 1 CRCs in California. Methods: We combined data from the AHA, the California Office of Statewide Health Planning and Development (OSHPD, and surveys to identify CRCs. We surveyed emergency department directors and nurse managers at all 24/7 PCI centers identified by the AHA to determine their post-OHCA care capabilities. The survey included questions regarding therapeutic hypothermia use and specialist availability and was pilot-tested prior to distribution. Cases of OHCA were identified in the 2011 OSHPD Patient Discharge Database using a “present on admission” diagnosis of cardiac arrest (ICD-9-CM code 427.5. We defined key level 1 CRC criteria as 24/7 PCI capability, therapeutic hypothermia, and annual volume ≥40 patients admitted with a “present on admission” diagnosis of cardiac arrest. Our primary outcome was the proportion of hospitals meeting these criteria. Descriptive statistics and 95% CI are presented. Results: Of the 333 acute care hospitals in California, 31 (9.3%, 95% CI 6.4-13% met level 1 CRC criteria. These hospitals treated 25% (1937/7780; 95% CI 24-26% of all admitted OHCA patients in California in 2011. Of the 125 hospitals identified as 24/7 PCI centers by the AHA, 54 (43%, 95% CI 34-52% admitted ≥40 patients following OHCA in 2011. Seventy (56%, 95% CI 47-65% responded to the survey; 69/70 (99%, 95% CI 92-100% reported having a therapeutic hypothermia protocol in effect by 2011.

    Full Text Available Cardiac arrest associated with spinal anaesthesia has been well researched. Myocardial stunning after successful resuscitation from cardiac arrest is seen in up to 2/3 rd of in-hospital cardiac arrests. Myocardial stunning after resuscitation from cardiac arrest associated with spinal anaesthesia has probably not been reported earlier. Our case, an ASA physical status I lady, posted for tubal reanastomosis surgery developed bradycardia followed by asystole, approximately 5 minutes after giving subarachnoid block. Return of spontaneous circulation (ROSC was achieved within 2 minutes with cardiopulmonary resuscitation (CPR and defibrillation for pulseless ventricular tachycardia. Patient developed delayed pulmonary oedema, which was probably due to myocardial stunning. In the present case, inadequate preloading could have precipitated bradycardia progressing to cardiac arrest which, after resuscitation led to reversible myocardial dysfunction. We conclude that early vasopressor infusion, titrated fluids and echocardiography should be considered in immediate post cardiac arrest phase following spinal anaesthesia.

    Cardiac arrest is the most common cause of death in North America. Neurocritical care interventions, including targeted temperature management (TTM), have significantly improved neurological outcomes in patients successfully resuscitated from cardiac arrest. Therefore, resuscitation following cardiac arrest was chosen as an emergency neurological life support protocol. Patients remaining comatose following resuscitation from cardiac arrest should be considered for TTM. This protocol will review induction, maintenance, and re-warming phases of TTM, along with management of TTM side effects. Aggressive shivering suppression is necessary with this treatment to ensure the maintenance of a target temperature. Ancillary testing, including electrocardiography, computed tomography and/or magnetic resonance imaging of the brain, continuous electroencephalography monitoring, and correction of electrolyte, blood gas, and hematocrit changes, are also necessary to optimize outcomes.

  15. Cerebral blood flow in humans following resuscitation from cardiac arrest

    International Nuclear Information System (INIS)

    Cerebral blood flow was measured by xenon-133 washout in 13 patients 6-46 hours after being resuscitated from cardiac arrest. Patients regaining consciousness had relatively normal cerebral blood flow before regaining consciousness, but all patients who died without regaining consciousness had increased cerebral blood flow that appeared within 24 hours after resuscitation (except in one patient in whom the first measurement was delayed until 28 hours after resuscitation, by which time cerebral blood flow was increased). The cause of the delayed-onset increase in cerebral blood flow is not known, but the increase may have adverse effects on brain function and may indicate the onset of irreversible brain damage

    One of the most important topics in the field of resuscitation at present is the drafting of the 2015 version of the Consensus on Science and Treatment Recommendation (CoSTR) by the International Liaison Committee on Resuscitation. The Japan Resuscitation Council is preparing its 2015 Guideline based on this CoSTR and plans to release it in October 2015. A critical change in the upcoming CoSTR is the adoption of the GRADE system. The new Guideline incorporating the GRADE system will surely be more scientific than the previous Guideline issued in 2010. Meanwhile, an important finding appeared in a report from Nielsen et al.: hypothermia at a targeted temperature of 33 degrees C did not confer a benefit versus 36 degrees in unconscious survivors of out-of-hospital cardiac arrest of presumed cardiac cause.

    We report the case of successful resuscitation after prolonged cardiac arrest during orthotopic liver transplantation. After reperfusion, the patient developed ventricular tachycardia, complicated by intracardiac clot formation and massive hemorrhage. Transesophageal echocardiography demonstrated stunned and nonfunctioning right and left ventricles, with developing intracardiac clots. Treatment with heparin, massive transfusion and prolonged cardiopulmonary resuscitation ensued for 51 minutes. Serial arterial blood gases demonstrated adequate oxygenation and ventilation during cardiopulmonary resuscitation. Cardiothoracic surgery was consulted for potential use of extracorporeal membrane oxygenation, however, the myocardial function improved and the surgery was completed without further intervention. On postoperative day 6, the patient was extubated without neurologic or cardiac impairment. The patient continues to do well 2 years posttransplant, able to perform independent daily activities of living and his previous job. This case underscores the potential for positive outcomes with profoundly prolonged, effective advanced cardiovascular life support in patients who experience postreperfusion syndrome. PMID:27233818

    For more than a decade, mild induced hypothermia (32 °C-34 °C) has been standard of care for patients remaining comatose after resuscitation from out-of-hospital cardiac arrest with an initial shockable rhythm, and this has been extrapolated to survivors of cardiac arrest with initially nonshockable rhythms and to patients with in-hospital cardiac arrest. Two randomized trials published in 2002 reported a survival and neurological benefit with mild induced hypothermia. One recent randomized trial reported similar outcomes in patients treated with targeted temperature management at either 33 °C or 36 °C. In response to these new data, the International Liaison Committee on Resuscitation Advanced Life Support Task Force performed a systematic review to evaluate 3 key questions: (1) Should mild induced hypothermia (or some form of targeted temperature management) be used in comatose post-cardiac arrest patients? (2) If used, what is the ideal timing of the intervention? (3) If used, what is the ideal duration of the intervention? The task force used Grading of Recommendations Assessment, Development and Evaluation methodology to assess and summarize the evidence and to provide a consensus on science statement and treatment recommendations. The task force recommends targeted temperature management for adults with out-of-hospital cardiac arrest with an initial shockable rhythm at a constant temperature between 32 °C and 36 °C for at least 24 hours. Similar suggestions are made for out-of-hospital cardiac arrest with a nonshockable rhythm and in-hospital cardiac arrest. The task force recommends against prehospital cooling with rapid infusion of large volumes of cold intravenous fluid. Additional and specific recommendations are provided in the document.

    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.

    Full Text Available Aim We have studied epidemiology of in-hospital cardiac arrest, characteristics of organizing a reanimationand its,procedures as well as its documenting.Methods We analyzed all resuscitation procedure data where anesthesiology reanimation teams (RT providedcardiopulmonary resuscitation (CPR during one-year period. We included resuscitation attemptsthat were initiated outside the Department of Anesthesiology, excluding incidents in operation rooms andIntensive Care Unit (ICU. Data on every cardiac arrest and CPR were entered in a special form.Results During one-year period 87 CPR were performed. Victims of cardiac arrest were principallyelderly patients (age 60 – 80, mostly male (60%. Most frequent victims were neurological patients(42%, surgical patients (21% and neurosurgical patients (10%. The leading cause of cardiac arrestwas primary heart disease, following neurological diseases and respiration disorders of severe etiology.In over 90% cases CPR was initiated by medical personnel in their respective departments, RT arrivedwithin 5 minutes in 73,56% cases. Initially survival was 32%, but full recovery was accomplished in 4patients out of 87 (4,6%.Conclusion Victims of cardiac arrest are patients whose primary disease contributes to occurrence ofcardiorespiratory complications. High mortality and low percentage of full recovery can be explainedby characteristics of patients (old age, nature and seriousness of primary disease which significantly affectthe outcome of CPR. In some cases a question is raised whether to initiate the CPR at all. We wouldlike to point out that continous monitoring of potentially critical patients may prevent cardiorespiratoryincidents whereas the quality and success of CPR may be improved by training of staff and better technicalequipment on the relevant locations in the in the hospital where such incidents usually occur.

    Objective: To examine the utility of bedside echocardiography in detecting the reversible causes of pulseless electrical activity (PEA) cardiac arrest and predicting the resuscitation outcomes.Methods: In this prospective interventional study,patients presenting with PEA cardiac arrest were randomized into two groups.In Group A,ultrasound trained emergency physicians performed echocardiography evaluating cardiac activity,right ventricle dilation,left ventricle function,pericardial effusion/tamponade and ⅣC size along with the advanced cardiac life support (ACLS) protocol.Patients in Group B solely underwent ACLS protocol without applying echocardiography.The presence or absence of mechanical ventricular activity (MVA) and evidences of PEA reversible causes were recorded.The return of spontaneous circulation (ROSC) and death were evaluated in both groups.Results: One hundred patients with the mean age of (58±6.1) years were enrolled in this study.Fifty patients (Group A) had echocardiography detected in parallel with cardiopulmonary resuscitation (CPR).Among them,7 patients (14%) had pericardial effusion,11 (22%) had hypovolemia,and 39 (78%) were revealed the presence of MVA.In the pseudo PEA subgroup (presence of MVA),43% had ROSC (positive predictive value) and in the true PEA subgroup with cardiac standstill (absence of MVA),there was no recorded ROSC (negative predictive value).Among patients in Group B,no reversible etiology was detected.There was no significant difference in resuscitation results between Groups A and B observed (P=0.52).Conclusion: Bedside echocardiography can identify some reversible causes of PEA.However,there are no significant changes in survival outcome between the echo group and those with traditional CPR.

    Use of dextrose in intravenous resuscitation fluids is common practice; however, this study indicates that 5% dextrose solutions, even if administered in physiologic quantities, greatly worsens the outcome of survivable cardiac arrest. Twelve adult male mongrel dogs were premedicated with morphine, anesthetized with halothane, instrumented, intubated, and ventilated. Each dog was first given 500 ml of either lactated Ringer's (LR) (n = 6) or 5% dextrose in LR (D5LR) (n = 6). Halothane was stopped and fibrillation was induced (60 Hz). Blood glucose just before cardiac arrest was 129 mg/dl in the LR dogs and was increased to 335 mg/dl in the D5LR dogs. After eight minutes of arrest, resuscitation, including internal cardiac massage and standard advanced cardiac life support drug protocols (modified for dogs), was begun. When stable cardiac rhythm was obtained, the chest was closed, and LR or D5LR continued until a total of 1L was given. A neurologic score (0 = normal to 100 = dead) was assigned at 1, 2, 6, and 24 hours. The LR group did not differ statistically from the D5LR group in operative time, number of defibrillatory shocks, time to spontaneous ventilation, time to extubation, or drugs required. Resuscitation was successful in all six LR and five of six D5LR group; however, by 2 hours after resuscitation and thereafter, D5LR group had a significantly greater neurologic deficit (p less than 0.05) than did the LR group. By 9 hours, four of six D5LR dogs displayed convulsive activity and died. At 24 hours the D5LR group had a greater (p less than 0.008) neurologic deficit (82 +/- 11) than did the LR group (21 +/- 7), which walked and ate. We conclude that the addition of 5% dextrose to standard intravenous fluids greatly increases the morbidity and mortality associated with cardiac resuscitation. PMID:3738770

Material and methods: In-hospital cardiac arrest teams at our hospital were instructed to complete a questionnaire following every emergency call between July 2011 and June 2013. Data on all resuscitation attempts were collected and analyzed. Results: A total of 65 in-hospital resuscitations were recorded in 42 males (64.6% and 23 females (35.4% (mean age 72.0±14.3 years. A total of 54 (83.1% cardiac arrests were witnessed; seven (10.8% showed a shockable rhythm at the time of the first ECG. Resuscitation attempts lasted 29.3±41.3 minutes, and 4.1±3.1 mg epinephrine was given. Return of spontaneous circulation could be achieved in 38 patients (58.5%; 29 (44.6% survived the first day, 23 (35.4% the seventh day, and 15 patients (23.1% were discharged alive. Significantly more in-hospital resuscitations were obtained for those performed during non-regular working hours (P<0.001, with higher neuron-specific enolase levels at 72 hours after resuscitation during nonregular working hours (P=0.04. Patients who were discharged alive were significantly younger (P=0.01, presented more often with an initial shockable rhythm (P=0.04, and had a shorter duration of resuscitation (P<0.001 with the need of a lower dose of epinephrine (P<0.001. Discussion: Survival rates following in-hospital resuscitation were poor at any time, but appear to depend less on time-dependent effects of the quality of resuscitation and more on time-dependent effects of recognition of cardiac arrests

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

    Symptomatic long QT syndrome in pediatric patients is a life-threatening condition. Sometimes, this pathology can be misdiagnosed and erroneously managed as generalized epilepsy due to similar clinical manifestations. The presented case discusses a 13-year-old female patient with generalized epilepsy since the age of 4, admitted for two episodes of resuscitated cardiac arrest due to torsades de pointes and ventricular fibrillation. The final diagnosis of congenital long QT was established and due to the patient's high-risk profile for future cardiac events, implantable cardiac defibrillator was subsequently indicated. Early recognition of congenital long QT and timing of cardiac therapy were crucial and potentially lower the incidence of fatal dysrhythmias commonly associated this condition. In high-risk patients, both medical and interventional therapy can be life-saving.

    Full Text Available The optimal treatment of a severe hemodynamic instability from shock to cardiac arrest in late term pregnant women is subject to ongoing studies. However, there is an increasing evidence that early “separation” between the mother and the foetus may increase the restoration of the hemodynamic status and, in the cardiac arrest setting, it may raise the likelihood of a return of spontaneous circulation (ROSC in the mother. This treatment, called Perimortem Cesarean Section (PMCS, is now termed as Resuscitative Hysterotomy (RH to better address the issue of an early Cesarean section (C-section. This strategy is in contrast with the traditional treatment of cardiac arrest characterized by the maintenance of cardiopulmonary resuscitation (CPR maneuvers without any emergent surgical intervention. We report the case of a prehospital perimortem delivery by Caesarean (C section of a foetus at 36 weeks of gestation after the mother’s traumatic cardiac arrest. Despite the negative outcome of the mother, the choice of performing a RH seems to represent up to date the most appropriate intervention to improve the outcome in both mother and foetus.

    Full Text Available Background: Performing immediate bystander Cardio Pulmonary Resuscitation (CPR is the most important factor that determines survival from cardiac arrest. Recommended mouth to mouth ventilation maneuver during CPR has led to lower rate of CPR performance in the population. Objectives: The present survey aimed to evaluate the willingness of nurses at Shiraz University of Medical Sciences for performing CPR versus chest-compression-only CPR. Patients and Methods: During a CPR course, we performed a survey on 25 nurses from Shiraz University of Medical Sciences, Iran. This survey included age and gender of the participants. In the first question, they were asked about their willingness to perform CPR with mouth to mouth breathing for witnessed cardiac arrest victims. In the second question, they were asked about their willingness to perform chest compression only for cardiac arrest victims. Results: Among the participating nurses, 96% were female with a mean age of 31 years. Only 40% were willing to perform CPR that requires mouth to mouth ventilation. On the other hand, 92% were willing to perform chest compression only without mouth to mouth ventilation. The mean age of the nurses who would do CPR was lower compared to those who would not. Conclusions: In this survey, we demonstrated that eliminating mouth to mouth ventilation maneuver could lead to markedly higher willingness to perform CPR for witnessed cardiac arrest victims in CPR trained nursing personnel. Our study is in agreement with other studies advocating that chest-compression-only CPR could lead to higher bystander resuscitation efforts.

    Background The choice of a defibrillation or a cardiopulmonary resuscitation (CPR)-first strategy in the treatment of prolonged cardiac arrest (CA) is still controversial.The purpose of this study was to compare the effects of defibrillation or CPR administered first on neurological prognostic markers in a porcine model of prolonged CA.Methods After 8 minutes of untreated ventricular fibrillation (VF),24 inbred Chinese Wuzhishan minipigs were randomized to receive either defibrillation first (ID group,n=12) or chest compression first (IC group,n=12).In the ID group,a shock was delivered immediately.If defibrillation failed to attain restoration of spontaneous circulation (ROSC),manual chest compressions were rapidly initiated at a rate of 100 compressions/min and a compression-to-ventilation ratio of 30:2.If VF persisted after five cycles of CPR,a second defibrillation attempt was made.In the IC group,chest compressions were delivered first,followed by a shock.After successful ROSC,hemodynamic status and blood samples were obtained at 0.5,1,2,4,6,and 24 hours after ROSC.Porcine-specific neuron-specific enolase (NSE) and S100B were measured from sera using enzyme-linked immunosorbent assays.Porcine cerebral performance category scores were used to evaluate preliminary neurological function following 24 hours recovery.Surviving pigs were sacrificed at 24 hours after ROSC and brains were removed for electron microscopy analysis.Results The number of shocks,total defibrillation energy,and time to ROSC were significantly lower in the ID group compared with the IC group.Compared with the IC group,S100B expression was decreased at 2 and 4 hours after ROSC,and NSE expression decreased at 6 and 24 hours after ROSC in the ID group.Brain tissue analysis showed that injury was attenuated in the ID group compared with the IC group.There were no significant differences between 6 and 24 hours survival rates.Conclusion Defibrillation first may result in a shorter time to ROSC and

    In this series of animal experiments on resuscitation after cardiac arrest we had a unique opportunity to measure hyperspectral near-infrared spectroscopy (hNIRS) parameters directly on the brain dura, or on the brain through the intact pig skull, and simultaneously the muscle hNIRS parameters. Simultaneously the arterial blood pressure and carotid and femoral blood flow were recorded in real time using invasive sensors. We used a novel hyperspectral signalprocessing algorithm to extract time-dependent concentrations of water, hemoglobin, and redox state of cytochrome c oxidase during cardiac arrest and resuscitation. In addition in order to assess the validity of the non-invasive brain measurements the obtained results from the open brain was compared to the results acquired through the skull. The comparison of hNIRS data acquired on brain surface and through the adult pig skull shows that in both cases the hemoglobin and the redox state cytochrome c oxidase changed in similar ways in similar situations and in agreement with blood pressure and flow changes. The comparison of simultaneously measured brain and muscle changes showed expected differences. Overall the results show feasibility of transcranial hNIRS measurements cerebral parameters including the redox state of cytochrome oxidase in human cardiac arrest patients.

    Full Text Available Introduction. Pulmonary embolism as a possible cause of acute heart failure is a potentially fatal condition that can cause death in all age groups. Patients successfully resuscitated after cardiac arrest have a high risk of increased mortality and their poor long­term outcome is often associated with severe neurological complications. Case Outline. This is a case report of a 67­year­old man after a successful cardiopulmonary resuscitation (CPR which was followed by therapeutic hypothermia (TH. The patient visited the dermatological outpatients’ department with clinical presentation of pain and swelling of the right leg, shortness of breath and chest pain. During examination the patient lost consciousness, stopped breathing and had cardiac arrest. ECG was done which registered asystole. We began CPR. After 59 minutes of resuscitation return of heartbeat was achieved. The patient was transported to the Emergency Department. On admission, after computerized tomography (CT of the chest confirmed massive pulmonary embolism (PE, the patient was administered thrombolytic therapy with Metalyse (tenecteplase and anti­coagulation therapy (heparin. After stabilization, therapeutic hypothermia was applied. Combination of EMCOOLSpad on the chest and abdomen and cold Ringer lactate 500 ml at 4°C was flushed. Temperature was decreased to 33°C and kept stabile for 24 hours. After eight days the patient was conscious with a minimal neurological deficit. Conclusion. As shown in this case report, and according to the rich experience elsewhere, cooling therapy after out­of­hospital cardiac arrest and successful CRP may be useful in preventing neurological complications.

    Full Text Available Cardiac arrest is defined as the sudden cessation of spontaneous ventilation and circulation. Within 15 seconds of cardiac arrest, the patient loses consciousness, electroencephalogram becomes flat after 30 seconds, pupils dilate fully after 60 seconds, and cerebral damage takes place within 90–300 seconds. It is essential to act immediately as irreversible damage can occur in a short time. Cardiopulmonary resuscitation (CPR is an attempt to restore spontaneous circulation through a broad range of interventions which are early defibrillation, high-quality and uninterrupted chest compressions, advanced airway interventions, and pharmacological interventions. Drugs should be considered only after initial shocks have been delivered (when indicated and chest compressions and ventilation have been started. During cardiopulmonary resuscitation, no specific drug therapy has been shown to improve survival to hospital discharge after cardiac arrest, and only few drugs have a proven benefit for short-term survival. This paper reviews current pharmacological treatment of cardiac arrest. There are three groups of drugs relevant to the management of cardiac arrest: vasopressors, antiarrhythmics, and other drugs such as sodium bicarbonate, calcium, magnesium, atropine, fibrinolytic drugs, and corticosteroids.

    This report describes a case of out-of-hospital cardiac arrest with spontaneous defibrillation and subsequent return of circulation after cessation of resuscitative efforts. A 47-year-old man was found in cardiac arrest and resuscitation was initiated. As no response was achieved, the efforts were withdrawn and final registered cardiac rhythm was ventricular fibrillation. Fifteen minutes later the patient was found to be normotensive and breathing spontaneously. The patient made a poor neurological recovery and died 3 months after the arrest. The authors are unable to give an explanation to the event, but suspect the effect of adrenaline combined with mild hypothermia to have contributed to the self-defibrillation of the myocardium.

    Cerebral metabolic alterations during cardiac arrest, cardiopulmonary resuscitation (CPR) and extracorporeal cardiopulmonary life support (ECLS) are poorly explored. Markers are needed for a more personalized resuscitation and post—resuscitation care. Aim of this study was to investigate early metabolic changes in the hippocampal CA1 region during ventricular fibrillation cardiac arrest (VF-CA) and ECLS versus conventional CPR. Male Sprague-Dawley rats (350g) underwent 8min untreated VF-CA followed by ECLS (n = 8; bloodflow 100ml/kg), mechanical CPR (n = 18; 200/min) until return of spontaneous circulation (ROSC). Shams (n = 2) were included. Glucose, glutamate and lactate/pyruvate ratio were compared between treatment groups and animals with and without ROSC. Ten animals (39%) achieved ROSC (ECLS 5/8 vs. CPR 5/18; OR 4,3;CI:0.7–25;p = 0.189). During VF-CA central nervous glucose decreased (0.32±0.1mmol/l to 0.04±0.01mmol/l; p<0.001) and showed a significant rise (0.53±0.1;p<0.001) after resuscitation. Lactate/pyruvate (L/P) ratio showed a 5fold increase (31 to 164; p<0.001; maximum 8min post ROSC). Glutamate showed a 3.5-fold increase to (2.06±1.5 to 7.12±5.1μmol/L; p<0.001) after CA. All parameters normalized after ROSC with no significant differences between ECLS and CPR. Metabolic changes during ischemia and resuscitation can be displayed by cerebral microdialysis in our VF-CA CPR and ECLS rat model. We found similar microdialysate concentrations and patterns of normalization in both resuscitation methods used. Institutional Protocol Number: GZ0064.11/3b/2011 PMID:27175905

    Full Text Available Purpose: 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. Methods: 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. Results: 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, P<0.001. Statistically significant improvement was also seen on the number of critical items completed (OR=3.75, 95% CI 2.71-5.19, total items completed (OR=4.55, 95% CI 3.4-6.11, and number of “excellent” scores on a Likert scale (OR=2.66, 95% CI 1.85-3.81. Conclusions: Nicaraguan resident physicians demonstrate improved ability to manage simulated cardiac arrest scenarios after participation in the Project SEMILLA resuscitation course and retain these skills.

    1993-08-01

    Open-chest cardiopulmonary resuscitation (CPR) is a promising method for non-traumatic cardiac arrest. In this preliminary study, we investigated the optimum timing of thoracotomy which brings high rate of return of spontaneous circulation (ROSC) and keeps the incidence of unnecessary thoracotomy minimal. Ninety-five adult patients with non-traumatic out-of-hospital cardiac arrest were analyzed. Of those, 26 patients were treated by the open-chest CPR in a prospective consecutive fashion. In this group, the ROSC rate was investigated in connection with the interval from hospital arrival, or ambulance call, to thoracotomy. Another 69 patients were treated by standard CPR. In this uncontrolled group, the interval from arrival at hospital to ROSC was investigated to define the 'natural hospital course' by the conventional treatment. Patient characteristics in the open-chest CPR group and the standard CPR group were similar. In the open-chest CPR group, 15 patients obtained ROSC. There was a tendency that the ROSC rate was highest in the patients with thoracotomy within 5 min of hospital arrival and declined as the timing of thoracotomy was delayed. Similar tendency was noted when the timing of thoracotomy was counted from the ambulance call. In the standard CPR group, only two patients obtained ROSC during the initial 5 min of hospital course. These results suggest that thoracotomy within 5 min of hospital arrival brings the highest ROSC rate while keeps the incidence of unnecessary thoracotomy acceptable. PMID:8210734

    Full Text Available Ambulance response times and resuscitation efforts are critical predictors of the survival rate after out-of-hospital cardiac arrests (OHCA. On the other hand, rural-urban differences in the OHCA survival rates are an important public health issue.We retrospectively reviewed the January 2011-December 2013 OHCA registry data of Kaohsiung City, Taiwan. With particular focus on geospatial variables, we aimed to unveil risk factors predicting the overall OHCA survival until hospital admission. Spatial analysis, network analysis, and the Kriging method by using geographic information systems were applied to analyze spatial variations and calculate the transport distance. Logistic regression was used to identify the risk factors for OHCA survival.Among the 4,957 patients, the overall OHCA survival to hospital admission was 16.5%. In the multivariate analysis, female sex (adjusted odds ratio:, AOR, 1.24 [1.06-1.45], events in public areas (AOR: 1.30 [1.05-1.61], exposure to automated external defibrillator (AED shock (AOR: 1.70 [1.30-2.23], use of laryngeal mask airway (LMA (AOR: 1.35 [1.16-1.58], non-trauma patients (AOR: 1.41 [1.04-1.90], ambulance bypassed the closest hospital (AOR: 1.28 [1.07-1.53], and OHCA within the high population density areas (AOR: 1.89 [1.55-2.32] were positively associated with improved OHCA survival. By contrast, a prolonged total emergency medical services (EMS time interval was negatively associated with OHCA survival (AOR: 0.98 [0.96-0.99].Resuscitative efforts, such as AED or LMA use, and a short total EMS time interval improved OHCA outcomes in emergency departments. The spatial heterogeneity of emergency medical resources between rural and urban areas might affect survival rate.

    State-of-the-art cardiopulmonary resuscitation (CPR) restores circulation with inconsistent blood-flow and pressure. Extracorporeal life support (ECLS) following CPR opens the opportunity for "controlled reperfusion". In animal experiments investigating CPR with ECLS, systemic anticoagulation before induced cardiac arrest is normal, but a major point of dispute, since preliminary heparinization in patients undergoing unwitnessed cardiac arrest is impossible. In this study, we investigated options for ECLS after an experimental 15 minutes normothermic cardiac arrest, without preceding anticoagulation, in pigs. Neurological recovery was assessed by a scoring system, electroencephalography and brain magnetic resonance imaging. Additionally, brain histology was performed on day seven after cardiac arrest. We demonstrated that preliminary heparin administration was not necessary for survival or neurological recovery in this setting. Heparin flushing of the cannulae seemed sufficient to avoid thrombus formation. These findings may ease the way to using ECLS in patients with sudden cardiac arrest. PMID:23827862

    Hypothermia has emerged as a potent neuroprotective modality following resuscitation from cardiac arrest. Although delayed hospital cooling has been demonstrated to improve outcome after cardiac arrest, in-field cooling begun immediately following the return of spontaneous circulation may be more beneficial. Cooling in the field following resuscitation, however, presents new challenges, in that the cooling method has to be portable, safe, and effective. Rapid infusion of intravenous fluid at 4 degrees C, the use of a cooling helmet, and cooling plates have all been proposed as methods for field cooling, and are all in various stages of clinical and animal testing. Whether field cooling will improve survival and neurologic outcome remains an important unanswered clinical question. PMID:19072587

  15. Combination of epinephrine with esmolol attenuates post-resuscitation myocardial dysfunction in a porcine model of cardiac arrest.

    Qian Zhang

    Full Text Available BACKGROUND: Recent experimental and clinical studies have indicated that the β-adrenergic effect of epinephrine significantly increases the severity of post resuscitation myocardial dysfunction. The aim of the study was to investigate whether the short-acting β₁-selective adrenergic blocking agent, esmolol, would attenuate post resuscitation myocardial dysfunction in a porcine model of cardiac arrest. METHODS AND RESULTS: After 8 min of untreated ventricular fibrillation and 2 min of basic life support, 24 pigs were randomized to three groups (n = 8 per group, which received central venous injection of either epinephrine combined with esmolol (EE group, epinephrine (EP group, or saline (SA group. Hemodynamic status and blood samples were obtained at 0, 30, 60, 120, 240 and 360 min after return of spontaneous circulation (ROSC. Surviving pigs were euthanatized at 24 h after ROSC, and the hearts were removed for analysis by electron microscopy, Western blotting, quantitative real-time polymerase chain reaction, and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL assay. Compared with the EP and SA groups, EE group had a better outcome in hemodynamic function, (improved dp/dt maxima and minima and cardiac output (P<0.05, and improved oxygen metabolism (oxygen delivery and oxygen consumption (P<0.05, which suggesting that EE can protect myocardial tissue from injury and improve post-resuscitation myocardial dysfunction. The protective effect of EE also correlated with reducing cardiomyocyte apoptosis, evidenced by reducing TUNEL-positive cells, increasing anti-apoptotic Bcl-2/Bax ratio and suppression of caspase-3 activity in myocardium. CONCLUSIONS: Esmolol, a short-acting β₁-selective adrenergic blocking agent, given during CPR has significant effects on attenuating post resuscitation myocardial dysfunction. The current study provides a potential pharmacologic target for post resuscitation myocardial dysfunction.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: A parada cardiorrespiratória (PCR ocorrida em ambulatório tem elevada mortalidade, sendo a sobrevida entre 5% e 35%. Dos pacientes que são reanimados uma percentagem elevada permanece com déficits neurológicos, resultantes das lesões ocorridas, tanto no período de ausência de circulação ou durante a reperfusão. No entanto a compreensão dos mecanismos da lesão cerebral não tem traduzido na melhoria do prognóstico. A hipotermia terapêutica após a reanimação parece ser uma opção válida associada à diminuição destas seqüelas neurológicas. O objetivo deste estudo foi rever a evidência científica relativa à abordagem do paciente reanimado após PCR. CONTEÚDO: Descrição e abordagem dos principais fatores de risco associados à lesão neurológica após PCR, bem como dos seus critérios de prognóstico.Feita pesquisa não sistemática na base de dados PubMed dos artigos referentes à abordagem terapêutica dos pacientes reanimados de parada cardíaca. As referências bibliográficas dos artigos de revisão foram igualmente analisadas. Elaboradas normas práticas para essa abordagem. CONCLUSÕES: Os pacientes que sobrevivem à PCR têm elevado risco de permanecer com lesões neurológicas graves. A hipotermia terapêutica e o controle das variáveis fisiológicas, com otimização da perfusão cerebral, podem melhorar o seu prognóstico.BACKGROUND AND OBJECTIVES: Out-of-hospital cardiac arrest is a major cause of death with survival rates as low as 5% to 35%.

    Full Text Available Abstract Background Overall survival rates for out-of-hospital cardiac arrest rarely exceed 5%. While bystander cardiopulmonary resuscitation (CPR can increase survival for cardiac arrest victims by up to four times, bystander CPR rates remain low in Canada (15%. Most cardiac arrest victims are men in their sixties, they usually collapse in their own home (85% and the event is witnessed 50% of the time. These statistics would appear to support a strategy of targeted CPR training for an older population that is most likely to witness a cardiac arrest event. However, interest in CPR training appears to decrease with advancing age. Behaviour surrounding CPR training and performance has never been studied using well validated behavioural theories. Methods/Design The overall goal of this study is to conduct a survey to better understand the behavioural factors influencing CPR training and performance in men and women 55 years of age and older. The study will proceed in three phases. In phase one, semi-structured qualitative interviews will be conducted and recorded to identify common categories and themes regarding seeking CPR training and providing CPR to a cardiac arrest victim. The themes identified in the first phase will be used in phase two to develop, pilot-test, and refine a survey instrument based upon the Theory of Planned Behaviour. In the third phase of the project, the final survey will be administered to a sample of the study population over the telephone. Analyses will include measures of sampling bias, reliability of the measures, construct validity, as well as multiple regression analyses to identify constructs and beliefs most salient to seniors' decisions about whether to attend CPR classes or perform CPR on a cardiac arrest victim. Discussion The results of this survey will provide valuable insight into factors influencing the interest in CPR training and performance among a targeted group of individuals most susceptible to

    We recently started a new collaborative project to develop improved Cardiac CT architectures and reconstruction algorithms. This paper presents a status update of the initial work in this project and we expect to be able to show several new results by the time of the conference. Firstly, we summarize the cardiac CT application needs and performance requirements. Secondly, we report on a study of cardiac CT architectures, which is still in progress. The architecture analysis requires in-depth understanding of the reconstruction process in terms of noise propagation, spatial resolution, Radon space completeness, and image artifacts. Thirdly, we present an evaluation framework based on simulations and measurements. We started implementing and verifying some advanced system models in our simulation framework. Finally, we present a high-level overview of the different challenges in cardiac CT and how different reconstruction techniques can overcome some of these challenges. (orig.)

    Airway management is an important component of resuscitation from out-of-hospital cardiac arrest (OHCA). The optimal approach to advanced airway management is unknown. The Pragmatic Airway Resuscitation Trial (PART) will compare the effectiveness of endotracheal intubation (ETI) and Laryngeal Tube (LT) insertion upon 72-h survival in adult OHCA. Encompassing United States Emergency Medical Services agencies affiliated with the Resuscitation Outcomes Consortium (ROC), PART will use a cluster-crossover randomized design. Participating subjects will include adult, non-traumatic OHCA requiring bag-valve-mask ventilation. Trial interventions will include (1) initial airway management with ETI and (2) initial airway management with LT. The primary and secondary trial outcomes are 72-h survival and return of spontaneous circulation. Additional clinical outcomes will include airway management process and adverse events. The trial will enroll a total of 3000 subjects. Results of PART may guide the selection of advanced airway management strategies in OHCA. PMID:26851059

    Medical support to deployed field forces is increasingly becoming a shared responsibility among allied nations. National military medical planners face several key challenges, including fiscal restraints, raised expectations of standards of care in the field and a shortage of appropriately trained specialists. Even so, medical services are now in high demand, and the availability of medical support may become the limiting factor that determines how and where combat units can deploy. The influence of medical factors on operational decisions is therefore leading to an increasing requirement for multinational medical solutions. Nations must agree on the common standards that govern the care of the wounded. These standards will always need to take into account increased public expectations regarding the quality of care. The purpose of this article is to both review North Atlantic Treaty Organization (NATO) policies that govern multinational medical missions and to discuss how recent scientific advances in prehospital battlefield care, damage control resuscitation and damage control surgery may inform how countries within NATO choose to organize and deploy their field forces in the future.

    Full Text Available Paediatric cardiac anaesthesia involves anaesthetizing very small children with complex congenital heart disease for major surgical procedures. The unique nature of this patient population requires considerable expertise and in-depth knowledge of the altered physiology. There have been several developments in the last decade in this subspecialty that has contributed to better care and improved outcome in this vulnerable group of patients. The purpose of this review is to present some of the recent advances in the anesthetic management of these children from preoperative evaluation to postoperative care. This article reviews the role of magnetic resonance imaging and contrast-enhanced magnetic resonance angiography in preoperative evaluation, the use of ultrasound to secure vascular access, the use of cuffed endotracheal tubes, the optimal haematocrit and the role of blood products, including the use of recombinant factor VIIa. It also deals with the advances in technology that have led to improved monitoring, the newer developments in cardiopulmonary bypass, the use of centrifugal pumps and extracorporeal membrane oxygenation and the role of DHCA. The role of new drugs, especially the α-2 agonists in paediatric cardiac anesthetic practice, fast tracking and effective postoperative pain management have also been reviewed.

    The American Heart Association and the European Resuscitation Council recently recommended that vasopressin can be used for cardiopulmonary resuscitation, instead of epinephrine. However, the guidelines do not discuss the effects of vasopressin during cerebral resuscitation. In this study, we intraperitoneally injected epinephrine and/or vasopressin during cardiopulmonary resuscitation in a rat model of asphyxial cardiac arrest. The results demonstrated that, compared with epinephrine alone, ...

    心跳骤停是临床医学中最为危急的事件之一,其发生发展过程涉及了一系列的病理生理学改变.近几年来,有关于心跳骤停复苏的研究有很多,也取得了一定的进展,但关于其各种不同类型心跳骤停的病理生理学改变的理解仍不是十分的全面,其有效地治疗药物和治疗手段也仍需要进一步的研究.因此,成功地制备与人类心跳骤停相似的动物模型就显得非常必要来,这不仅是深入研究心跳骤停复苏病理生理学改变的重要基础和研究途径,也是研制其治疗药物及方法的有效手段.本文重点讨论家兔各种类型心跳骤停复苏模型不同的研究方法.%Cardiac arrest is one of the most critical events in the clinical medicine, involving a series ofpathophysiological changes. In recent years, there are many researches about cardiac arrest and cardiopulmonary resuscitation and have achieved some progress, however, it they are not enough, the explanation of the pathophysiological changes in different types of cardiac arrest is not very comprehensive, and the effective drugs and treatments which will benefit cardiac arrest also still need further study. The successed establishment of different types of animal model of cardiac arrest and resuscitation that similar to human is not only the important foundation and research approach for further study of the pathophysiology in various tapes of cardiac arrest, but also the necessary means for the research of much more effective drugs and treatment which will benefit the patients who suffered cardiac arrest. This paper mainly focused on the different research methods in various types of cardiac arrest animal model in rabbits.

    Full Text Available Abstract Background In 1999, the laryngeal tube (VBM Medizintechnik, Sulz, Germany was introduced as a new supraglottic airway. It was designed to allow either spontaneous breathing or controlled ventilation during anaesthesia; additionally it may serve as an alternative to endotracheal intubation, or bag-mask ventilation during resuscitation. Several variations of this supraglottic airway exist. In our study, we compared ventilation with the laryngeal tube suction for single use (LTS-D and a bag-mask device. One of the main points of the revised ERC 2005 guidelines is a low no-flow-time (NFT. The NFT is defined as the time during which no chest compression occurs. Traditionally during the first few minutes of resuscitation NFT is very high. We evaluated the hypothesis that utilization of the LTS-D could reduce the NFT compared to bag-mask ventilation (BMV during simulated cardiac arrest in a single rescuer manikin study. Methods Participants were studied during a one day advanced life support (ALS course. Two scenarios of arrhythmias requiring defibrillation were simulated in a manikin. One scenario required subjects to establish the airway with a LTS-D; alternatively, the second scenario required them to use BMV. The scenario duration was 430 seconds for the LTS-D scenario, and 420 seconds for the BMV scenario, respectively. Experienced ICU nurses were recruited as study subjects. Participants were randomly assigned to one of the two groups first (LTS-D and BMV to establish the airway. Endpoints were the total NFT during the scenario, the successful airway management using the respective device, and participants' preference of one of the two strategies for airway management. Results Utilization of the LTS-D reduced NFT significantly (p Conclusion In our manikin study, NFT was reduced significantly when using LTS-D compared to BMV. During cardiac arrest, the LTS-D might be a good alternative to BMV for providing and maintaining a patent airway

    Levels of brain creatine phosphokinase (CPK), glutamic oxalic transaminase, lactate dehydrogenase, and lactate in lumbar cerebrospinal fluid (CSF) were analyzed as an adjunctive study in a randomized clinical trial evaluating the effects of thiopental loading intravenously in comatose survivors of cardiac arrest. Three hospitals participated and a total of 62 cases of enzyme changes were studied. Enzyme levels but not lactate were higher at 48 hours than at 24 hours after restoration of spontaneous circulation. All enzymes were highly correlated with one another at 24 and 48 hours (P < .001). There was a significant negative correlation between cerebral recovery and increased CPK levels at 24 hours (P < .05), and a highly significant correlation with all three enzyme levels at 48 hours (P < .0001). The increase of cytosolic enzyme activity in lumbar CSF reflects permanent brain damage, and there is a relationship between activity levels and cerebral outcome. PMID:7945601

    Although therapeutic hypothermia is an effective treatment for post-resuscitation brain injury after cardiac arrest (CA), the underlying mechanism remains unclear. Vacuolar H(+)-ATPase (V-ATPase) plays a key role in cellular adaption to a hypoxic environment. This study sought to evaluate the effect of mild hypothermia on V-ATPase and its involvement in neuroprotection after CA. Male Sprague-Dawley rats were subjected to a 6-min CA, resuscitated successfully, and then assigned to either the normothermia (NT) group or the hypothermia (HT) group. Rats were further divided into 2 subgroups based on the time of euthanasia, either 3 or 24 h after CA (NT-3 h, HT-3 h; NT-24 h, HT-24 h). Mild hypothermia was induced following CA and maintained at 33°C for 2 h. Neurologic deficit scores were used to determine the status of neurological function. Brain specimens were analyzed by TUNEL assay, western blotting, and immunohistochemistry. V-ATPase activity was estimated by subtracting total ATP hydrolysis from the bafilomycin-sensitive activity. Mild hypothermia improved the neurological outcome (HT-24 h: 34.3 ± 16.4 vs NT-24 h: 50.3 ± 17.4) and significantly decreased neurocyte apoptosis 24 h after resuscitation. Mild hypothermia significantly increased V0a1 compared to NT-3 h; V0a1 expression was associated with a decrease in the cleaved caspase 3 expression. These findings suggested that mild hypothermia inhibits CA-induced apoptosis in the hippocampus, which may be associated with reduced V-ATPase impairment. These data provide new insights into the protective effects of hypothermia in vivo. PMID:27323115

    Smith, Mark F

    2013-08-01

    Recent advances in clinical cardiac SPECT instrumentation are reviewed from a systems perspective. New hardware technologies include pixelated scintillator and semiconductor detector elements; photodetectors such as position-sensitive photomultiplier tubes (PSPMT), avalanche photodiodes (APD) and silicon photomultipliers (SiPM); and novel cardiac collimation methods. There are new approaches for positioning detectors and controlling their motion during cardiac imaging. Software technology advances include iterative image reconstruction with modeling of Poisson statistics and depth-dependent collimator response. These new technologies enable faster acquisitions, the lowering of administered activity and radiation dose, and improved image resolution. Higher sensitivity collimators are a significant factor enabling faster acquisitions. Several clinical systems incorporating new technologies are discussed and different system designs can achieve similar performance. With detector elements such as APDs, SiPMs and semiconductors that are insensitive to magnetic fields, the potential for cardiac SPECT imagers that are MRI compatible opens up new frontiers in clinical cardiac research and patient care.

    2014-01-01

    The heart is commonly involved in various forms of amyloidosis and cardiomyopathy is a major cause of morbidity and mortality in these patients. Diagnosis of cardiac amyloidosis is often delayed due to nonspecific presenting symptoms and failure to recognize early signs of amyloid heart disease on routine cardiac imaging. Treatment of cardiac amyloidosis depends upon the type of amyloid protein. Systemic chemotherapy with or without stem cell transplantation is used to treat immunoglobulin-related amyloidosis and liver transplantation is used for familial transthyretin amyloidosis in select patients. Clinical trials with siRNA for the treatment of transthyretin amyloid cardiomyopathies and amyloid protein stabilizers are ongoing. Prognosis depends on the type of amyloid protein with poorer outcomes noted in immunoglobulin light-chain amyloidosis. Supportive care forms the cornerstone of management and advancements in cardiac imaging and proteomics are expected to positively impact our ability to diagnose, prognosticate and treat cardiac amyloidosis.

    2015-07-01

    Cardiac arrest occurs in approximately 1:12,000 parturients. Among nonpregnant patients who have in-hospital cardiac arrest, those whose spontaneous circulation does not return within 15 to 20 minutes have a high risk of death and disability, so life support efforts are generally stopped after this period. However, among parturients, witnessed in-hospital arrest is often reversible and has a better prognosis. We describe a successful clinical outcome after maternal cardiac arrest and 55 minutes of advanced cardiac life support. This case underscores the importance of high-quality cardiopulmonary resuscitation and raises questions about the appropriate duration of resuscitation efforts in otherwise healthy young mothers with a potentially reversible cause of arrest.

    AIM: To investigate the clinical and pathologic findings,and to discuss the pathophysiology of hepatocellular carcinoma with cardiac metastasis.METHODS: Eight hepatoma patients with cardiac metastasis, who were treated by surgical excision from 1993 to 2006, were retrospectively studied. Detailed clinical parameters were analyzed.RESULTS: Of those eight patients, two (25%) were women and six (75%) were men, with the mean age of 50 years (range, 40-70 years). The presentations included: asymptomatic (75%), heart failure (25%), and pulmonary embolism (12.5%). All lesions involved the right atrium, and extended to the lung (12.5%), inferior vena cava (25%), and left atrium (12.5%). The level of tumor marker, alpha-fetal protein, was not correlated with the severity of metastasis or disease prognosis.Moreover, the availably estimated doubling time was less than 3 mo. The pathological findings included variable hemorrhage and necrosis. The survival time following surgery also varied from one month to more than 30 mo.CONCLUSION: Hepatoma metastasis to the heart was detected in all eight patients. This study demonstrates that surgery might help the outcome in such cases.

    2009-07-01

    After sudden cardiac arrest, successful resuscitation and return of spontaneous circulation, a multi-faceted ischaemia/reperfusion related disorder develops. This condition now known as post resuscitation syndrome is characterised by marked increases in the inflammatory response and changes in coagulation profile and vascular reactivity. Additionally, the production of reactive oxygen species and activation of cytotoxic cascades of metabolism add to these injury mechanisms resulting in multiorgan perfusion deficits and dysfunction. Especially in the cerebrum these injuries may be the cause of significant morbidity and mortality. Recent evidence has shown that statins (3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors) exert numerous beneficial effects in cardiovascular diseases irrespective of the lipid status. Remarkably, these pleiotropic effects seem to extended beyond cardiovascular diseases such as immunomodulative and antioxidative properties. We hypothesised that administration of statins early in the post resuscitation phase would prove beneficial in the resuscitated patient via several pleiotropic effects. These include inhibition of excessive coagulation and inflammatory response, suppression of oxygen radical production and improved vascular reactivity. The discussed effects are mediated via multiple pathways activated in the cardiac arrest victim, to which statins have been shown to have a beneficial modulating effect in experimental settings and non-cardiac arrest patients. To test this hypothesis in clinical practice, a randomized, controlled trial with sufficient power and standardised post resuscitation treatment would be necessary. The generally good tolerance of statin therapy with minimal adverse effects would support this experiment, although a parenteral form of the drug to ensure adequate dosage might be a prerequisite.

    The knowledge and skills surrounding the practice of cardiopulmonary resuscitation (CPR) have become essential to intensive care nurses and to nurses in general. With formalized training and refresher courses becoming more common in this country, it is evident that after relatively short periods of time the knowledge and skills acquired at such courses may be lost. While much consideration has been given to the content of both Basic and Advanced Cardiac Life Support (BCLS and ACLS) courses, relatively little attention has been paid to the educational issues surrounding CPR training. This paper explores some of these issues from the perspective of adult learning (andragogy). Research is cited from a wide range of sources to illustrate that CPR skill and knowledge deterioration is not unique to nursing, and that educational techniques exist which may improve current educational practices.

    Over the past decade, simulation-based education has emerged as a new and exciting adjunct to traditional bedside teaching and learning. Simulation-based education seems particularly relevant to emergency medicine training where residents have to master a very broad skill set, and may not have sufficient real clinical opportunities to achieve competence in each and every skill. In 2006, the Emergency Medicine program at Queen's University set out to enhance our core curriculum by developing and implementing a series of simulation-based teaching sessions with a focus on resuscitative care. The sessions were developed in such as way as to satisfy the four conditions associated with optimum learning and improvement of performance; appropriate difficulty of skill, repetitive practice, motivation, and immediate feedback. The content of the sessions was determined with consideration of the national training requirements set out by the Royal College of Physicians & Surgeons of Canada. Sessions were introduced in a stepwise fashion, starting with a cardiac resuscitation series based on the AHA ACLS guidelines, and leading up to a more advanced resuscitation series as staff became more adept at teaching with simulation, and as residents became more comfortable with this style of learning. The result is a longitudinal resuscitation curriculum that begins with fundamental skills of resuscitation and crisis resource management (CRM) in the first 2 years of residency and progresses through increasingly complex resuscitation cases where senior residents are expected to play a leadership role. This paper documents how we developed, implemented, and evaluated this resuscitation-based simulation curriculum for Emergency Medicine postgraduate trainees, with discussion of some of the challenges encountered.

    Full Text Available In the US alone, several hundred thousands die of sudden cardiac arrests each year. Basic life support defined as chest compressions and ventilations and early defibrillation are the only factors proven to increase the survival of patients with out-of-hospital cardiac arrest, and are key elements in the chain of survival defined by the American Heart Association. The current cardiopulmonary resuscitation guidelines treat all patients the same, but studies show need for more individualiza- tion of treatment. This review will focus on ideas on how to strengthen the weak parts of the chain of survival including the ability to measure the effects of therapy, improve time efficiency, and optimize the sequence and quality of the various components of cardiopulmonary resuscitation.

    Sepsis is a common and life-threatening inflammatory response to severe infection treated with antibiotics and fluid resuscitation. Despite the central role of intravenous fluid in sepsis management, fundamental questions regarding which fluid and in what amount remain unanswered. Recent advances in understanding the physiologic response to fluid administration, and large clinical studies examining resuscitation strategies, fluid balance after resuscitation, colloid versus crystalloid solutions, and high- versus low-chloride crystalloids, inform the current approach to sepsis fluid management and suggest areas for future research.

    2015-06-01

    The resuscitative thoracotomy (RT) is an important procedure in the management of penetrating trauma. As it is performed only in patients with peri-arrest physiology or overt cardiac arrest, survival is low. Experience is also quite variable depending on volume of penetrating trauma in a particular region. Survival ranges from 0% to as high as 89% depending on patient selection, available resources, and location of RT (operating or emergency rooms). In this article, published guidelines are reviewed as well as outcomes. Technical considerations of RT and well as proper training, personnel, and location are also discussed. PMID:25342073

  15. DNA methylation in cardiac fibrosis: New advances and perspectives

    International Nuclear Information System (INIS)

    Cardiac fibrosis is characterized by net accumulation of extracellular matrix (ECM) proteins in the cardiac interstitium, and contributes to both systolic and diastolic dysfunction in many cardiac pathophysiologic conditions. More specifically, cardiac fibroblasts are activated by a variety of pathological stimuli, thereby undergoing proliferation, differentiation to myofibroblasts, and production of various cytokines and ECM proteins. Thus, understanding the biological processes of cardiac fibroblasts will provide novel insights into the underlying mechanisms of cardiac fibrosis. DNA methylation is an important epigenetic mechanism, which often occurs in response to environmental stimuli and is crucial in regulating gene expression. The aberrant methylation of CpG island promoters of selected genes is the prominent epigenetic mechanism by which gene transcription can be effectively silenced. Aberrant hypermethylation of a few selected genes such as RASSF1A plays an important role in facilitating fibrotic fibroblast activation and in driving fibrosis. In this review we will discuss the mechanisms of DNA methylation and their implications for cardiac fibroblasts activation and fibrosis. Control of DNA methylation may serve as a new strategy for anti-fibrotic therapy

    2016-10-01

    More than 4 decades after the creation of the Brooke and Parkland formulas, burn practitioners still argue about which formula is the best. So it is no surprise that there is no consensus about how to resuscitate a thermally injured patient with a significant comorbidity such as heart failure or cirrhosis or how to resuscitate a patient after an electrical or inhalation injury or a patient whose resuscitation is complicated by renal failure. All of these scenarios share a common theme in that the standard rule book does not apply. All will require highly individualized resuscitations. PMID:27600129

    Full Text Available Capnography continues to be an important tool in measuring expired carbon dioxide (CO 2 . Most recent Advanced Cardiac Life Support (ACLS guidelines now recommend using capnography to ascertain the effectiveness of chest compressions and duration of cardiopulmonary resuscitation (CPR. Based on an extensive review of available published literature, we selected all available peer-reviewed research investigations and case reports. Available evidence suggests that there is significant correlation between partial pressure of end-tidal CO 2 (PETCO 2 and cardiac output that can indicate the return of spontaneous circulation (ROSC. Additional evidence favoring the use of capnography during CPR includes definitive proof of correct placement of the endotracheal tube and possible prediction of patient survival following cardiac arrest, although the latter will require further investigations. There is emerging evidence that PETCO 2 values can guide the initiation of extracorporeal life support (ECLS in refractory cardiac arrest (RCA. There is also increasing recognition of the value of capnography in intensive care settings in intubated patients. Future directions include determining the outcomes based on capnography waveforms PETCO 2 values and determining a reasonable duration of CPR. In the future, given increasing use of capnography during CPR large databases can be analyzed to predict outcomes.

    Rates of survival after cardiac arrest are low and correlate with the quality of cardiopulmonary resuscitation (CPR). Devices that deliver automated CPR (A-CPR) can provide sustained and effective chest compressions, which are especially useful during patient transfer and while simultaneous invasive procedures are being performed. The use of such devices can also release members of resuscitation teams for other work. This article presents a case study involving a man with acute myocardial infarction complicated by cardiogenic shock and pulmonary oedema. It describes how ED nursing and medical teams worked together to deliver A-CPR, discusses the use of A-CPR devices in a tertiary cardiac centre, and highlights the advantages of using such devices.

    Many controversies and uncertainties surround resuscitation of hemorrhagic shock caused by vascular trauma. Whereas the basic pathophysiology is better understood, much remains to be learned about the many immunologic cascades that lead to problems beyond those of initial fluid resuscitation or operative hemostasis. Fluid therapy is on the verge of significant advances with substitute oxygen carriers, yet surgeons are still beset with questions of how much and what type of initial fluid to provide. Finally, the parameters chosen to guide therapy and the methods used to monitor patients present other interesting issues. PMID:11766174

  6. Enhancing pediatric safety: assessing and improving resident competency in life-threatening events with a computer-based interactive resuscitation tool

    International Nuclear Information System (INIS)

    Though rare, allergic reactions occur as a result of administration of low osmolality nonionic iodinated contrast material to pediatric patients. Currently available resuscitation aids are inadequate in guiding radiologists' initial management of such reactions. To compare radiology resident competency with and without a computer-based interactive resuscitation tool in the management of life-threatening events in pediatric patients. The study was approved by the IRB. Radiology residents (n=19; 14 male, 5 female; 19 certified in basic life support/advanced cardiac life support; 1 certified in pediatric advanced life support) were videotaped during two simulated 5-min anaphylaxis scenarios involving 18-month-old and 8-year-old mannequins (order randomized). No advance warning was given. In half of the scenarios, a computer-based interactive resuscitation tool with a response-driven decision tree was available to residents (order randomized). Competency measures included: calling a code, administering oxygen and epinephrine, and correctly dosing epinephrine. Residents performed significantly more essential interventions with the computer-based resuscitation tool than without (72/76 vs. 49/76, P<0.001). Significantly more residents appropriately dosed epinephrine with the tool than without (17/19 vs. 1/19; P<0.001). More residents called a code with the tool than without (17/19 vs. 14/19; P = 0.08). A learning effect was present: average times to call a code, request oxygen, and administer epinephrine were shorter in the second scenario (129 vs. 93 s, P=0.24; 52 vs. 30 s, P<0.001; 152 vs. 82 s, P=0.025, respectively). All the trainees found the resuscitation tool helpful and potentially useful in a true pediatric emergency. A computer-based interactive resuscitation tool significantly improved resident performance in managing pediatric emergencies in the radiology department. (orig.)

    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.

  10. The effectiveness of a 'train the trainer' model of resuscitation education for rural peripheral hospital doctors in Sri Lanka.

    Bishan N Rajapakse

    Full Text Available BACKGROUND: Sri Lankan rural doctors based in isolated peripheral hospitals routinely resuscitate critically ill patients but have difficulty accessing training. We tested a train-the-trainer model that could be utilised in isolated rural hospitals. METHODS: Eight selected rural hospital non-specialist doctors attended a 2-day instructor course. These "trained trainers" educated their colleagues in advanced cardiac life support at peripheral hospital workshops and we tested their students in resuscitation knowledge and skills pre and post training, and at 6- and 12-weeks. Knowledge was assessed through 30 multiple choice questions (MCQ, and resuscitation skills were assessed by performance in a video recorded simulated scenario of a cardiac arrest using a Resuci Anne Skill Trainer mannequin. RESULTS/DISCUSSION/CONCLUSION: Fifty seven doctors were trained. Pre and post training assessment was possible in 51 participants, and 6-week and 12-week follow up was possible for 43, and 38 participants respectively. Mean MCQ scores significantly improved over time (p<0.001, and a significant improvement was noted in "average ventilation volume", "compression count", and "compressions with no error", "adequate depth", "average depth", and "compression rate" (p<0.01. The proportion of participants with compression depth ≥40mm increased post intervention (p<0.05 and at 12-week follow up (p<0.05, and proportion of ventilation volumes between 400-1000mls increased post intervention (p<0.001. A significant increase in the proportion of participants who "checked for responsiveness", "opened the airway", "performed a breathing check", who used the "correct compression ratio", and who used an "appropriate facemask technique" was also noted (p<0.001. A train-the-trainer model of resuscitation education was effective in improving resuscitation knowledge and skills in Sri Lankan rural peripheral hospital doctors. Improvement was sustained to 12 weeks for most

    Faldmo, L; Kravitz, M

    1993-05-01

    Initial management of minor and moderate, uncomplicated burn injury focuses on wound management and patient comfort. Initial management of patients with major burn injury requires airway support, fluid resuscitation for burn shock, treatment for associated trauma and preexisting medical conditions, management of adynamic ileus, and initial wound treatment. Fluid resuscitation, based on assessment of the extent and depth of burn injury, requires administration of intravenous fluids using resuscitation formula guidelines for the initial 24 hours after injury. Inhalation injury complicates flame burns and increases morbidity and mortality. Electrical injury places patients at risk for cardiac arrest, metabolic acidosis, and myoglobinuria. Circumferential full-thickness burns to extremities compromise circulation and require escharotomy or fasciotomy. Circumferential torso burns compromise air exchange and cardiac return. Loss of skin function places patients at risk for hypothermia, fluid and electrolyte imbalances, and systemic sepsis. The first 24 hours after burn injury require aggressive medical management to assure survival and minimize complications. PMID:8489882

    Cardiac arrest as the first symptom of coronary artery disease is not uncommon. Some of previously healthy people with sudden cardiac arrest may be saved by effective resuscitation and post-resuscitative therapy. The majority of cardiac arrest patients experience the cardiac arrest outside of the hospital, in which case early recognition of lifelessness, commencement of basic life support and entry to professional care without delay are the prerequisites for recovery. After the heart has started beating again, the clinical picture of post-resuscitation syndrome must be recognized and appropriate treatment utilized. PMID:22204143

    2016-09-01

    Amyloidosis is caused by extracellular deposition of abnormal protein fibrils, resulting in destruction of tissue architecture and impairment of organ function. The most common forms of systemic amyloidosis are light-chain and transthyretin-related (ATTR). ATTR can result from an autosomal dominant hereditary transmission of mutated genes in the transthyretin or from a wild-type form of disease (ATTRwt), previously known as senile cardiac amyloidosis. With the aging of the worldwide population, ATTRwt will emerge as the most common type of cardiac amyloidosis that clinicians encounter. Diagnosis of systemic amyloidosis is often delayed, either because of the false assumption that it is a rare disease, or because of misdiagnosis as a result of mistaking it with other conditions. Clinicians must integrate clinical clues from history, physical examination, and common diagnostic tests to raise suspicion for ATTRwt. The historical gold standard for diagnosis of cardiac amyloid is endomyocardial biopsy analysis with pathological distinction of precursor protein type, but this method often results in delayed diagnosis because of the limited availability of expertise to perform and interpret the endomyocardial biopsy specimen. Emerging noninvasive imaging modalities provide easier, accurate screening for ATTRwt. These modalities include advanced echocardiography, using strain imaging and the myocardial contraction fraction; nuclear scintigraphy, which can differentiate between ATTR and light-chain cardiac amyloid; and cardiac magnetic resonance imaging, using extracellular volume measurement, late gadolinium enhancement, and distinct T1 mapping. These novel approaches reveal insights into the prevalence, clinical course, morphological effects, and prognosis of ATTRwt. PMID:27568874

    2006-03-01

    The science and practice of resuscitation is recognised and endorsed on an international level, yet for more than a decade it has appeared in the literature alongside words such as witnessing or witnessed to signify the practice of family presence during a resuscitation attempt. This paper explores the meaning of witnessed resuscitation using the process for concept analysis proposed by Rodgers. The term resuscitation is explored, followed by identification of relevant uses of the concept of witnessed resuscitation. The reader is introduced to conceptual variations that challenge the way in which the concept has become associated with family or relatives presence in the resuscitation room of an accident and emergency department. Conceptual clarity is further enhanced through the identification of references, antecedents and consequences of witnessed resuscitation and by providing a model case of the concept that includes its defining attributes.

    2016-01-01

    Hemorrhagic shock is a principal cause of death among trauma patients within the first 24 hours after injury. Optimal fluid resuscitation strategies have been examined for nearly a century, more recently with several randomized controlled trials. Hypotensive resuscitation, also called permissive hypotension, is a resuscitation strategy that uses limited fluids and blood products during the early stages of treatment for hemorrhagic shock. A lower-than-normal blood pressure is maintained until operative control of the bleeding can occur. The randomized controlled trials examining restricted fluid resuscitation have demonstrated that aggressive fluid resuscitation in the prehospital and hospital setting leads to more complications than hypotensive resuscitation, with disparate findings on the survival benefit. Since the populations studied in each randomized controlled trial are slightly different, as is the timing of intervention and targeted vitals, there is still a need for a large, multicenter trial that can examine the benefit of hypotensive resuscitation in both blunt and penetrating trauma patients.

    The American Heart Association and the European Resuscitation Council recently recommend-ed that vasopressin can be used for cardiopulmonary resuscitation, instead of epinephrine. However, the guidelines do not discuss the effects of vasopressin during cerebral resuscitation. In this study, we intraperitoneally injected epinephrine and/or vasopressin during cardiopul-monary resuscitation in a rat model of asphyxial cardiac arrest. The results demonstrated that, compared with epinephrine alone, the pathological damage to nerve cells was lessened, and the levels of c-Jun N-terminal kinase and p38 expression were signiifcantly decreased in the hippo-campus after treatment with vasopressin alone or the vasopressin and epinephrine combination. No signiifcant difference in resuscitation effects was detected between vasopressin alone and the vasopressin and epinephrine combination. These results suggest that vasopressin alone or the vasopressin and epinephrine combination suppress the activation of mitogen-activated protein kinase and c-Jun N-terminal kinase signaling pathways and reduce neuronal apoptosis during cardiopulmonary resuscitation.

    In the 43 years since it was first described, cardiopulmonary resuscitation (CPR) has grown from an obscure medical theory to a basic first aid skill taught to adults and is now the near-universal technique used in CPR instruction. This article provides insight into the history of CPR. We explore the phenomenon of sudden cardiac arrest, the historical roots of CPR, current practice data and recommendations, and the society's role in the development of this life-saving technique. We conclude with a review of CPR's economic impact on the healthcare system and the ethical and policy issues surrounding CPR. PMID:17179837

    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.

  5. CT findings of the brain post cardiopulmonary resuscitation

    International Nuclear Information System (INIS)

    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.)

    A 94-year-old woman undergoing surgery for simple repair of a duodenal perforation experienced a sudden massive hemorrhage (1500 mL) when the duodenum was separated from adjacent structures. Hemodynamic stability was re-established when fluids were replaced. After the abdominal wall was closed, increased amplitude of the QRS wave was observed and heart rate slowed until there was no pulse. Electromechanical dissociation (EMD) was diagnosed and cardiopulmonary resuscitation was started. When EMD persisted after 40 minutes, resuscitative measures were stopped and the ventilator was disconnected, though orotracheal intubation and arterial and electrocardiographic monitoring were maintained. After 2 or 3 minutes, heart rhythm restarted spontaneously and arterial pressure waves reappeared on the monitor. The patient progressed well for 72 hours, after which she developed septic shock and multiorgan failure, dying 18 days later. The Lazarus phenomenon may be more common than the medical literature would indicate, possibly because a large gap in our understanding of the pathophysiology of the phenomenon underlies anecdotes about "miracles". As we wait for adequate international consensus on a protocol for monitoring the withdrawal of resuscitative measures, we should act prudently before definitively certifying death. The case we report occurred during a surgical intervention in which the patient had received general anesthesia. We believe that the causes that might explain the Lazarus phenomenon are quite different in that context than they would be in a nonsurgical setting, such that it would be useful to create a national database to keep a record of such intraoperative events.

    Objective To investigate the efficiency and safety of the automated external defibrillator (AED); and to compare the defibrillating efficacy between the domestic AED and the imported AED. Method Fourteen Peking white swine weighed (30 ± 1 ) kg, were anaesthetized and arterial cannula was inserted into the left femoral artery for collecting blood samples and measuring artery blood pressure, cardiac output (CO) and external vascular lung water index (EVWI) by using PiCCO monitor, and another cannula was inserted into the left femoral vein to place an electrode as a temporary pace maker, and then ventricular fibrillation (VF) was induced by using a programmed electrical stimulation instrument. The swine were divided into two groups randomly ( random number) after VF was confirmed by electrocardio-monitor,and the domestic made AED (M group, n = 7) or imported AED (Z group, n = 7) were used respectively in 7 swine of each group. The electrodes of defibrillator were stuck to the precordium and sternum separately, and defibrillation was delivered by the AED signal. The entire procedure of defibrillation was repeated four times. The number of defibrillation delivery required to get normal cardiac rhythm was recorded. Twenty minutes after restoration of spontaneous circulation (ROSC), blood sample was taken to measure myocardial enzyme. The CO and EVWI were measured too. Measurement data was analyzed by repeated ANOVA and enumeration data was analyzed by Chi-square test. A value of P <0.05 was regarded as being significant statistical difference. Results There were 54 episodes of VF induced in 14 swine and only one swine in Z group was dead after 2nd episode of VF, resulting in 98.1% success rate of resuscitation. There were 37 defibrillation deliveries given to swine of M group, and 75.0% produced normal cardiac rhythm after the first delivery of defibrillation,whereas 80.0% in Z group after 32 defibrillation deliveries. The length of time from AED turned on to the

    Fluid resuscitation of burn patients is commonly initiated using modified Brooke or Parkland formula. The fluid infusion rate is titrated up or down hourly to maintain adequate urine output and other endpoints. Over-resuscitation leads to morbid complications. Adherence to paper-based protocols, flow sheets, and clinical practice guidelines is associated with decreased fluid resuscitation volumes and complications. Computerized tools assist providers. Although completely autonomous closed-loop control of resuscitation has been demonstrated in animal models of burn shock, the major advantages of open-loop and decision-support systems are identifying trends, enhancing situational awareness, and encouraging burn team communication.

    Full Text Available Abstract Background Suboptimal bag ventilation in cardiopulmonary resuscitation (CPR has demonstrated detrimental physiological outcomes for cardiac arrest patients. In light of recent guideline changes for resuscitation, there is a need to identify the efficacy of bag ventilation by prehospital care providers. The objective of this study was to evaluate bag ventilation in relation to operator ability to achieve guideline consistent ventilation rate, tidal volume and minute volume when using two different capacity self-inflating bags in an undergraduate paramedic cohort. Methods An experimental study using a mechanical lung model and a simulated adult cardiac arrest to assess the ventilation ability of third year Monash University undergraduate paramedic students. Participants were instructed to ventilate using 1600 ml and 1000 ml bags for a length of two minutes at the correct rate and tidal volume for a patient undergoing CPR with an advanced airway. Ventilation rate and tidal volume were recorded using an analogue scale with mean values calculated. Ethics approval was granted. Results Suboptimal ventilation with the use of conventional 1600 ml bag was common, with 77% and 97% of participants unable to achieve guideline consistent ventilation rates and tidal volumes respectively. Reduced levels of suboptimal ventilation arouse from the use of the smaller bag with a 27% reduction in suboptimal tidal volumes (p = 0.015 and 23% reduction in suboptimal minute volumes (p = 0.045. Conclusion Smaller self-inflating bags reduce the incidence of suboptimal tidal volumes and minute volumes and produce greater guideline consistent results for cardiac arrest patients.

    Objective To compare the hemodynamic effect of standard-cardiopulmonary resuscitation (S-CPR) and of CPR by cardiac massage under the diaphragmatic muscle (D-CPR), and to evaluate the feasibility of D-CPR. Methods Twenty healthy New Zealand rabbits were randomly divided into two groups, one group receiving S-CPR (n= 10) and the other group receiving D-CPR (n=10). Cardiac arrest was induced by asphyxiation at the end expiration for 8 minutes. After the hemodynamic situation was stable for 5 minutes before asphyxiation, the readings of ascending aorta systolic pressure (AOS) and diastolic pressure (AOD), transcutaneous oxygen saturation (SpO2), right atrial systolic pressure (RASP), right atrial diastolic pressure (RADP), and electrocardiogram were recorded consecutively to the end of the experiment. The mean arterial pressure (MAP) of ascending aorta and coronary perfusion pressure (CPP) were calculated, The rate of restoration of spontaneous circulation (ROSC) and the survival rate in a short duration of 6 hours were observed. Results Five rabbits in S-CPR group and 8 in D-CPR group were successfully resuscitated and obtained ROSC (50%, 80%, P=20. 05). Six hours survival rate was 400% in S-CRP group and 500% in D-CPR group. The comparisons between the two groups on AOS, AOD, MAP and CPP respectively showed that at 1 minute and 5 minutes during resuscitation the respective variables were higher in the D-CPR group than that in the S-CPR group (all P<0. 05). Compared to the bemodynamics before asphyxiation, the MAP and CPP in the D-CPR group increased 54. 1% and 33.4% of basic value at 1 minute, and they were 60. 0% and 41.8% at 5 minutes, while the AOS and AOD in the S-CPR group only increased by an average of 37. 3% and 16.5% at 1 minute, and they were 38. 5% and 17. 1% at 5 minutes, respectively. After ROSC, the hemodynamic variations of the D-CPR rabbits were more stable than those of S-CPR rabbits. Conclusion D-CPR can provide higher arterial pressure, cardiac

    (1) Emergency thoracotomy can be a lifesaving procedure in critically injured patients who present with no detectable pulse or blood pressure. (2) Emergency thoracotomy is nonproductive if cardiac electrical activity is absent. (3) Best results are achieved in patients with chest injuries and the worst results in those with isolated blunt abdominal injury. (4) Survival was better if patient was taken directly to the operating room with ongoing cardiopulmonary resuscitation. (5) Prehospital airway control, volume resuscitation and cardiopulmonary resuscitation play a significant role in improving the outcome in traumatized patients who undergo emergency thoracotomy.

    Historically, recommendations for neonatal resuscitation were largely based on dogma, but there is renewed interest in performing resuscitation studies at birth. The emphasis for resuscitation following birth asphyxia is administering effective ventilation, as adequate lung aeration leads not only to an increase in oxygenation but also increased pulmonary blood flow and heart rate. To aerate the lung, an initial sustained inflation can increase heart rate, oxygenation, and blood pressure recovery much faster when compared with standard ventilation. Hyperoxia should be avoided, and extra oxygen given to restore cardiac function and spontaneous breathing should be titrated based on oxygen saturations. PMID:27524447

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.

    The evolution of the human in caring for others is reflected in the development of cardiopulmonary resuscitation (CPR).

  20. Do Radiologists Want/Need Training in Cardiopulmonary Resuscitation?

    International Nuclear Information System (INIS)

    Purpose: Prompt and effective cardiopulmonary resuscitation (CPR) decreases morbidity and mortality following cardiopulmonary arrest. Radiologists are frequently confronted with severely ill patients, who may deteriorate at any time. Furthermore, they have to be aware of life-threatening reactions towards contrast media. This study was designed to assess experience and self-estimation of German-speaking radiologists in CPR and cardiac defibrillation (CD). Material and Methods: 650 German-speaking radiologists were audited by a specially designed questionnaire, which was sent via e-mail. The answers were expected to be re-mailed within a 2-month period. Results: The response rate was 12.6%. 72.8% of the responders had performed at least 1 CPR (range 9.5 ± 13.1) and 37% at least 1 CD. 67.9% had had opportunities to attend training courses, which had been utilized by 41.8% of them. The last training of the responders was more than 2 years ago in 69.2% and more than 5 years ago in 37%. Of all responders 75.6% expressed the need for further education. Conclusion: The small response rate indicates the small importance of CPR in the subpopulation surveyed. The vast majority of the responders, however, showed interest in basic and advanced life support and advocated regular updates. It seems reasonable that radiological Dept. themselves should organize courses in order to cope with their specific situations

  2. Extracorporeal membrane oxygenation for pediatric cardiac arrest.

    2015-02-01

    Extracorporeal cardiopulmonary resuscitation (ECPR) remains a promising treatment for pediatric patients in cardiac arrest unresponsive to traditional cardiopulmonary resuscitation. With venoarterial extracorporeal support, blood is drained from the right atrium, oxygenated through the extracorporeal circuit, and transfused back to the body, bypassing the heart and lungs. The use of artificial oxygenation and perfusion thus provides the body a period of hemodynamic stability, while allowing resolution of underlying disease processes. Survival rates for ECPR patients are higher than those for traditional cardiopulmonary resuscitation (CPR), although neurological outcomes require further investigation. The impact of duration of CPR and length of treatment with extracorporeal membrane oxygenation vary in published reports. Furthermore, current guidelines for the initiation and use of ECPR are limited and may lead to confusion about appropriate use of this support. Many ethical concerns arise with this advanced form of life support. More often than not, the dilemma is not whether to withhold ECPR, but rather when to withdraw it. Although clinicians must decide if ECPR is appropriate and when further intervention is futile, the ultimate burden of choice is left to the patient's caregivers. Offering support and guidance to the patient's family as well as the patient is essential. PMID:25639578

    Subdiaphragmatic exsanguination is a major cause of death in civilian trauma. In a 1-year review of 867 consecutive admissions to a Level I Trauma Center, a 4.3 per cent incidence (37 patients) of infradiaphragmatic exsanguination was found. Eleven per cent of all abdominal injuries and 35 per cent of pelvic fractures sustained massive hemorrhage. A treatment protocol incorporating immediate airway control, MAST device, super-large bore venous access, warming rapid infusors, immediate type O blood transfusion, emergency department thoracotomy, and emergent operation as required, produced an overall mortality of 54 per cent. Mortality was higher for pelvic fracture (59%) than abdominal injury (43%). No patient survived ED thoracotomy. Continued developments in resuscitation techniques, as well as prehospital, and operative care are required to reduce mortality from exsanguinating hemorrhage. PMID:3355017

    Full Text Available Along with the improvement of survival after cancer, cardiotoxicity due to antineoplastic treatments has emerged as a clinically relevant problem. Potential cardiovascular toxicities due to anticancer agents include QT prolongation and arrhythmias, myocardial ischemia and infarction, hypertension and/or thromboembolism, left ventricular (LV dysfunction, and heart failure (HF. The latter is variable in severity, may be reversible or irreversible, and can occur soon after or as a delayed consequence of anticancer treatments. In the last decade recent advances have emerged in clinical and pathophysiological aspects of LV dysfunction induced by the most widely used anticancer drugs. In particular, early, sensitive markers of cardiac dysfunction that can predict this form of cardiomyopathy before ejection fraction (EF is reduced are becoming increasingly important, along with novel therapeutic and cardioprotective strategies, in the attempt of protecting cardiooncologic patients from the development of congestive heart failure.

  7. Outcome of cardiopulmonary resuscitation - predictors of survival

    International Nuclear Information System (INIS)

    To assess the outcomes of patients undergoing cardiopulmonary resuscitation (CPR). Data were collected retrospectively of all adult patients who underwent CPR. Clinical outcomes of interest were survival at the end of CPR and survival at discharge from hospital. Factors associated with survival were evaluated using logistic regression analysis. Of the 159 patients included, 55 (35%) were alive at the end of CPR and 17 (11%) were discharged alive from the hospital. At the end of CPR, univariate logistic regression analysis found the following factors associated with survival: cardiac arrest within hospital as compared to outside the hospital (odds ratio = 2.8, 95% CI = 1.27-6.20, p-value = 0.01), both cardiac and pulmonary arrest as compared to either cardiac or pulmonary arrest (odds ratio = 0.37, 95% CI = 0.19- 0.73, p-value = 0.004), asystole as cardiac rhythm at presentation (odds ratio = 0.47, 95% CI = 0.24-0.93, p-value = 0.03), and total atropine dose given during CPR (odds ratio = 0.78, 95% CI = 0.62-0.97, p-value = 0.02). In multivariate logistic regression, cardiac arrest within hospital (odds ratio = 2.52, 95% CI = 1.06-5.99, p-value = 0.04) and both cardiac and pulmonary arrest as compared to cardiac or pulmonary arrest (odds ratio = 0.44, 95% CI = 0.21-0.91, p-value = 0.03) were associated with survival at the end of CPR. At the time of discharge from hospital, univariate logistic regression analysis found following factors that were associated with survival: cardiac arrest within hospital (odds ratio = 8.4, 95% CI = 1.09-65.64, p-value = 0.04), duration of CPR (odds ratio = 0.91, 95% CI = 0.85-0.96, p-value = 0.001), and total atropine dose given during CPR (odds ratio = 0.68, 95% CI = 0.47-0.99, p-value = 0.05). In multivariate logistic regression analysis cardiac arrest within hospital (odds ratio 8.69, 95% CI = 1.01-74.6, p-value = 0.05) and duration of CPR (odds ratio 0.92, 95% CI = 0.87-0.98, p-value = 0.01) were associated with survival at

    Objective To study the effects of different doses of vitamin C( Vit C )on serum cardiac troponin Ⅰ ( cTn Ⅰ )in delayed resuscitative rats with severe burn. Methods 40 Wistar rats were randomly divided into four groups( n = 10 ) : sham - operated group,delayed resuscitative group,low - dose Vit C group and high - dose Vit C group. Animals were anesthetized by intraperitoneal injection of sodium pentobarbital at 30 mg/kg, and then depilated by 10% sodium sulfide. 24 h later,the same anesthesia was conducted again,and rats in sham - operated group received water bath below waist at 37 ℃ for 18 s,while those in the other three groups were burned by hot water bath at 92 ℃ . 6 h later, all burn rats were injected with Ringer lactate solution at 40 mg/kg to cause delayed resuscitation. In two Vit C groups, additional Vit C was injected at 30 mg/kg or 250 mg/kg. After that, blood samples were obtained for the measurement of serum cTn Ⅰ , malondaildehyde( MDA )content, superoxide dismutases( SOD ) activity. Results cTn Ⅰ and MDA contents decreased while SOD activity increased significantly in the two Vit C groups compared with delayed resuscitative group( P < 0. 01 ). These changes were more obvious in high - dose group than those in low - dose group( P<0. 05 ). Conclusion Vit C treatment during the period of delayed resuscitation following sever burn can protect myocardium,and high - dose Vit C is of protective effects superior to low - dose one. The mechanisms may be related to its inhibition of oxygen free radicals and lipid peroxidation.%目的 研究不同剂量维生素C(Vit C)对烧伤后延迟复苏大鼠血清肌钙蛋白Ⅰ(cTnⅠ)的影响,以了解Vit C对烧伤后延迟复苏心肌的保护作用.方法 40只Wistar大鼠随机分成4组:假手术组、延迟复苏组、Vit C低剂量组及Vit C高剂量组.复制烧伤模型30 h后,检测血清cTnⅠ、丙二醛(MDA)含量及超氧化物歧化酶(SOD)活性变化.结果 使用Vit C可以降

    Vasopressin administration may be a promising therapy in the management of various shock states. In laboratory models of cardiac arrest, vasopressin improved vital organ blood flow, cerebral oxygen delivery, the rate of return of spontaneous circulation, and neurological recovery compared with epinephrine (adrenaline). In a study of 1219 adult patients with cardiac arrest, the effects of vasopressin were similar to those of epinephrine in the management of ventricular fibrillation and pulseless electrical activity; however, vasopressin was superior to epinephrine in patients with asystole. Furthermore, vasopressin followed by epinephrine resulted in significantly higher rates of survival to hospital admission and hospital discharge. The current cardiopulmonary resuscitation guidelines recommend intravenous vasopressin 40 IU or epinephrine 1mg in adult patients refractory to electrical countershock. Several investigations have demonstrated that vasopressin can successfully stabilize hemodynamic variables in advanced vasodilatory shock. Use of vasopressin in vasodilatory shock should be guided by strict hemodynamic indications, such as hypotension despite norepinephrine (noradrenaline) dosages >0.5 mug/kg/min. Vasopressin must never be used as the sole vasopressor agent. In our institutional routine, a fixed vasopressin dosage of 0.067 IU/min (i.e. 100 IU/50 mL at 2 mL/h) is administered and mean arterial pressure is regulated by adjusting norepinephrine infusion. When norepinephrine dosages decrease to 0.2 microg/kg/min, vasopressin is withdrawn in small steps according to the response in mean arterial pressure. Vasopressin also improved short- and long-term survival in various porcine models of uncontrolled hemorrhagic shock. In the clinical setting, we observed positive effects of vasopressin in some patients with life-threatening hemorrhagic shock, which had no longer responded to adrenergic catecholamines and fluid resuscitation.

  13. Advance care planning preferences among dialysis patients and factors influencing their decisions

    International Nuclear Information System (INIS)

    To determine the resuscitation preferences of hemodialysis (HD) Saudi patients, we conducted a cross-sectional, observational descriptive questionnaire study in two major tertiary hospitals in Saudi Arabia from March to December 2007. We enrolled all the patients on HD for two years or more, and excluded the patients who were transplant candidates, confused, or demented. The questionnaire was composed of 4 sections. The first 3 sections were concerned with demographic data, education levels, employment, family size, number of children, and functionality status besides knowledge about cardiopulmonary resuscitation (CPR), mechanical ventilation, and ICU admission. The fourth section contained different scenarios and questions on personal and preferences such as end of life decisions, medical interventions, CPR, ICU admission, and the decision maker in these events. A total of 100 patients (53% males, 67% Saudis, and 85% married) were enrolled in the study. The mean duration on dialysis was 6.0 years (+- 4.1). More than 70% of the patients viewed themselves as above average in the religiosity score, and 44% disclosed a good life quality. More than 95% had little or no knowledge about cardiac resuscitation, intubation, and mechanical ventilation. The majority of the patients authorized their treating physician to decide for them about cardiac resuscitation in case they did not make advanced directives and only 22% believed that this decision should be made by their family members. If their physician believed their condition was hopeless, 77% preferred to stay at home. We conclude that the majority of our patients had limited awareness about cardiac resuscitation measures. The majority of the patients trust their physicians to decide about the futility of resuscitation. Patients were able to decide reasonably well when they are well informed. (author)

    The environmental and logistical constraints of the prehospital setting make it a challenging place for the treatment of trauma patients. This is perhaps more pronounced in the management of battlefield casualties before extraction to definitive care. In seeking solutions, interest has been renewed in implementing damage control resuscitation principles in the prehospital setting, a concept termed remote damage control resuscitation. These developments, while improving conflict survival rates, are not exclusive to the military environment, with similar situations existing in the civilian setting. By understanding the pathophysiology of shock, particularly the need for oxygen debt repayment, improvements in the assessment and management of trauma patients can be made. Technology gaps have previously hampered our ability to accurately monitor the prehospital trauma patient in real time. However, this is changing, with devices such as tissue hemoglobin oxygen saturation monitors and point-of-care lactate analysis currently being refined. Other monitoring modalities including newer signal analysis and artificial intelligence techniques are also in development. Advances in hemostatic resuscitation are being made as our understanding and ability to effectively monitor patients improve. The reevaluation of whole-blood use in the prehospital environment is yielding favorable results and challenging the negative dogma currently associated with its use. Management of trauma-related airway and respiratory compromise is evolving, with scope to improve on currently accepted practices. The purpose of this review is to highlight the challenges of treating patients in the prehospital setting and suggest potential solutions. In doing so, we hope to maintain the enthusiasm from people in the field and highlight areas for prehospital specific research and development, so that improved rates of casualty survival will continue.

    Stem cells are primitive self renewing undifferentiated cell that can be differentiated into various types of specialized cells like nerve cell, skin cells, muscle cells, intestinal tissue, and blood cells. Stem cells live in bone marrow where they divide to make new blood cells and produces peripheral stem cells in circulation. Under proper environment and in presence of signaling molecules stem cells begin to develop into specialized tissues and organs. These unique characteristics make them very promising entities for regeneration of damaged tissue. Day by day increase in incidence of heart diseases including left ventricular dysfunction, ischemic heart disease (IHD), congestive heart failure (CHF) are the major cause of morbidity and mortality. However infracted tissue cannot regenerate into healthy tissue. Heart transplantation is only the treatment for such patient. Due to limitation of availability of donor for organ transplantation, a focus is made for alternative and effective therapy to treat such condition. In this review we have discussed the new advances in stem cells such as use of cord stem cells and iPSC technology in cardiac repair. Future approach of CB cells was found to be used in tissue repair which is specifically observed for improvement of left ventricular function and myocardial infarction. Here we have also focused on how iPSC technology is used for regeneration of cardiomyocytes and intiating neovascularization in myocardial infarction and also for study of pathophysiology of various degenerative diseases and genetic disease in research field.

    The inflammatory state after burn injury is characterized by an increase in capillary permeability that results in protein and fluid leakage into the interstitial space, increasing resuscitative requirements. Although the mechanisms underlying increased capillary permeability are complex, damage from reactive oxygen species plays a major role and has been successfully attenuated with antioxidant therapy in several disease processes. However, the utility of antioxidants in burn treatment remains unclear. Vitamin C is a promising antioxidant candidate that has been examined in burn resuscitation studies and shows efficacy in reducing the fluid requirements in the acute phase after burn injury.

    The American Heart Association (AHA) commends the recently released Institute of Medicine (IOM) report, Strategies to Improve Cardiac Arrest Survival: A Time to Act (2015). The AHA recognizes the unique opportunity created by the report to meaningfully advance the objectives of improving outcomes for sudden cardiac arrest. For decades, the AHA has focused on the goal of reducing morbidity and mortality from cardiovascular disease though robust support of basic, translational, clinical, and population research. The AHA also has developed a rigorous process using the best available evidence to develop scientific, advisory, and guideline documents. These core activities of development and dissemination of scientific evidence have served as the foundation for a broad range of advocacy initiatives and programs that serve as a foundation for advancing the AHA and IOM goal of improving cardiac arrest outcomes. In response to the call to action in the IOM report, the AHA is announcing 4 new commitments to increase cardiac arrest survival: (1) The AHA will provide up to $5 million in funding over 5 years to incentivize resuscitation data interoperability; (2) the AHA will actively pursue philanthropic support for local and regional implementation opportunities to increase cardiac arrest survival by improving out-of-hospital and in-hospital systems of care; (3) the AHA will actively pursue philanthropic support to launch an AHA resuscitation research network; and (4) the AHA will cosponsor a National Cardiac Arrest Summit to facilitate the creation of a national cardiac arrest collaborative that will unify the field and identify common goals to improve survival. In addition to the AHA's historic and ongoing commitment to improving cardiac arrest care and outcomes, these new initiatives are responsive to each of the IOM recommendations and demonstrate the AHA's leadership in the field. However, successful implementation of the IOM recommendations will require a timely

    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.

    As trauma systems develop, more patients can potentially benefit from immediate surgery. With in-house surgeons available, enthusiasm for direct transfer from the scene to the operating room (OR) has developed in many institutions. The purpose of this study was to define precisely which patients should be taken to the OR for resuscitation. Three hundred twenty-three patients were taken to the OR directly from the field during a 4-year period (6.9% of trauma activations). Indications included the following: (1) cardiac arrest--one vital sign present, (2) persistent hypotension despite field intravenous fluid, and (3) uncontrolled external hemorrhage. A board-certified surgeon and resuscitation team met the field transport team in the OR in all cases. Cardiopulmonary resuscitation for patients with blunt trauma was not accompanied by survival even with immediate surgery by a trained surgeon and it wastes valuable OR resources. Patients with prehospital hypotension unresponsive to fluid resuscitation indicate the need for rapid surgery. Patients with blunt injuries even with hypotension infrequently undergo operations in less than 20 minutes and can be resuscitated in traditional areas where better roentgenograms are obtained. Penetrating injuries to the chest and abdomen with hypotension are the primary indications for OR resuscitation. It can be anticipated with field communication and accompanied by enhanced survival.

    BACKGROUND: Batroxobin has been found to have protective effect on cerebral ischemia-reperfusion,and cardiopulmonary resuscitation (CPR) is the common cause of global brain ischemia-reperfusion.OBJECTIVE: To observe the effect of Batroxobin on the morphological results of cerebral cortex and hippocampus in rabbit models of CPR, and the changes of serum concentration of tumor necrosis factor alpha (TNF- α) after CPR.DESIGN: A randomized controlled observation.SETTING: Laboratory of the Department of Burns, Changhai Hospital affiliated to the Second Military Medical University of Chinese PLA.MATERIALS: Thirty healthy New Zealand rabbits of 2.5 - 3.0 kg, either male or female, were used. Kits for TNF- α determination were provided by LIFEKEY BioMeditech Company (USA).METHODS: The experiments were carried out in the laboratory of Department of Burns, Changhai Hospital from February 2001 to January 2002. The 32 rabbits were randomly divided into sham-operated group (n=8),conventional resuscitation group (n=12) and Batroxobin-treated group (n=12). The animals in the conventional resuscitation group and Batroxobin-treated group were anesthetized, then induced into modified Pittsburg's model of mechanical ventricular fibrillation. Sham-operated group was discharged on the chest wall, which did not cause ventricular fibrillation. Conventional resuscitation group and Batroxobin-treated group were exposed to 6 minutes of cardiac arrest induced by ventricular fibrillation, then the resuscitation began. A dosage of 0.3 Bu/kg of Batroxobin was administered to the rabbits in the Batroxobin-treated group at the beginning of resuscitation. Blood sample was collected at 4 and 12 hours after CPR to determine the concentration of TNF- α in serum. After the second blood collection, brain tissue was taken out immediately,and the forms of nerve cells in cerebral cortex and hippocampal CA1 region were observed under light microscope.MAIN OUTCOME MEASURES: ① TNF-α concentration in

    Full Text Available Survivability characteristics after cardiopulmonary resuscitation in the population with spinal cord injury (SCI are unclear but may be useful for advanced care planning discussions with patients. Retrospective evaluation from records of all SCI patients over 10 yr at a Department of Veterans Affairs medical center who experienced in-hospital cardiac arrest was performed. Demographic data and other common measurements were recorded. Thirty-six male subjects were identified, and only two patients survived to discharge (5.5% survival rate, both of whom were admitted for nonacute issues and were asymptomatic shortly before the cardiac arrest. The mean age at the time of cardiopulmonary arrest was 62.4 yr, with a mean time from cardiac arrest to death of 3.02 d. No significant demographic parameters were identified. Overall, SCI likely portends worse outcome for acutely ill patients in the situation of a cardiac arrest. Conclusions are limited by sample size.

We decided to investigate the circumstances, incidence and outcome of cardiopulmonary resuscitation (CPR at a tertiary hospital in India, in relation to various factors, including extensive basic life support and advanced cardiac life support training programme for all nurses and doctors. Methods: It has been over a decade and a half with periodical updates and implementation of newer guidelines prepared by various societies across the world about CPR for both in-hospital and out-of hospital cardiac arrests (IHCA and OHCA. We conducted a prospective study wherein all cardiac arrests reported in the hospital consecutively for 12 months were registered for the study and followed their survival up to 1-year. Statistical analysis was performed by using Chi-square test for significant differences in proportions applied to various parameters of the study. Results: The main outcome measures were; (following CPR return of spontaneous circulation, survival for 24 h, survival from 24 h to 6 weeks or discharge, alive at 1-year. For survivors, an assessment was made about their cerebral performance and overall performance and accordingly graded. All these data were tabulated. Totally 419 arrests were reported in the hospital, out of which 413 were in-hospital arrests. Out of this 260 patients were considered for resuscitation, we had about 27 survivors at the end of 1-year follow-up (10.38%. Conclusion: We conclude by saying there are many factors involved in good clinical outcomes following IHCAs and these variable factors need to be researched further.

    Cardiovascular disease has become the most serious health threat and represents the major cause of morbidity and mortality in China, as in other industrialized nations. During the past few decades, China's economic boom has tremendously improved people's standard of living but has also changed their lifestyle, increasing the prevalence of cardiovascular disease, the so-called 'disease of modern civilization'. This new trend has attracted a significant amount of research. Many of the studies conducted by Chinese investigators are orientated towards understanding the molecular mechanisms of cardiovascular disease. At the molecular level, the long-standing consensus is that cardiovascular disease is associated with a sequence mutation (genetic anomaly) and expression deregulation (epigenetic disorder) of protein-coding genes. However, new research data have established the non-protein-coding genes microRNAs (miRNAs) as a central regulator of the pathogenesis of cardiac disease and a potential new therapeutic target for cardiovascular disease. These small non-coding RNAs have also been subjected to extensive, rigorous investigations by Chinese researchers. Over the years, a large body of studies on miRNAs in cardiovascular disease has been conducted by Chinese investigators, yielding fruitful research results and a better understanding of miRNAs as a new level of molecular mechanisms for the pathogenesis of cardiac disease. In this review, we briefly summarize the current status of research in the field of miRNAs and cardiovascular disease in China, highlighting the advances made in elucidating the role of miRNAs in various cardiac conditions, including cardiac arrhythmia, myocardial ischaemia, cardiac hypertrophy and heart failure. We have also examined the potential of miRNAs as novel diagnostic biomarkers and therapeutic targets. PMID:25393505

  9. Myocardial perfusion imaging for predicting cardiac events in Japanese patients with advanced chronic kidney disease: 1-year interim report of the J-ACCESS 3 investigation

    International Nuclear Information System (INIS)

    Whether myocardial perfusion imaging (MPI) can predict cardiac events in patients with advanced conservative chronic kidney disease (CKD) remains unclear. The present multicenter prospective cohort study aimed to clarify the ability of MPI to predict cardiac events in 529 patients with CKD and estimated glomerular filtration rates (eGFR) 2 without a definitive diagnosis of coronary artery disease. All patients were assessed by stress-rest MPI with 99mTc-tetrofosmin and analyzed using summed defect scores and QGS software. Cardiac events were analyzed 1 year after registration. Myocardial perfusion abnormalities defined as summed stress score (SSS) ≥4 and ≥8 were identified in 19 and 7 % of patients, respectively. At the end of the 1-year follow-up, 33 (6.2 %) cardiac events had occurred that included cardiac death, sudden death, nonfatal myocardial infarction, and hospitalization due to heart failure. The event-free rates at that time were 0.95, 0.90, and 0.81 for groups with SSS 0-3, 4-7, and ≥8, respectively (p = 0.0009). Thus, patients with abnormal SSS had a higher incidence of cardiac events. Multivariate Cox regression analysis showed that SSS significantly impacts the prediction of cardiac events independently of eGFR and left ventricular ejection fraction. MPI would be useful to stratify patients with advanced conservative CKD who are at high risk of cardiac events without adversely affecting damaged kidneys. (orig.)

    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.

    Cardiac arrest is associated with high morbidity and mortality. Better-quality bystander cardiopulmonary resuscitation training, cardiocerebral resuscitation principles, and intensive post-resuscitation hospital care have improved survival. However, cognitive and functional impairment after cardiac arrest remain areas of concern. Research focus has shifted beyond prognostication in the immediate post-arrest period to identification of mechanisms for long-term brain injury and implementation of promising protocols to reduce neuronal injury. These include therapeutic temperature management (TTM), as well as pharmacologic and psychological interventions which also improve overall neurological function. Comprehensive assessment of cognitive function post-arrest is hampered by heterogeneous measures among studies. However, the domains of attention, long-term memory, spatial memory, and executive function appear to be affected. As more patients survive cardiac arrest for longer periods of time, there needs to be a greater focus on interventions that can enhance cognitive and psychosocial function post-arrest. PMID:27311306

  14. Resuscitation of newborn in high risk deliveries

    International Nuclear Information System (INIS)

    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)

    Introduction 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. Methods 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. Results 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

    Tension pneumothorax can occur at any time during cardiopulmonary resuscitation (CPR) with external cardiac massage and invasive ventilation either from primary or iatrogenic rib fractures with concomitant pleural or parenchymal injury. Airway injury can also cause tension pneumothorax during CPR. This article presents the case of a 41-year-old woman who suffered cardiopulmonary arrest after undergoing elective mandibular surgery. During CPR the upper airway could not be secured by orotracheal intubation due to massive craniofacial soft tissue swelling. A surgical airway was established with obviously unrecognized iatrogenic tracheal perforation and subsequent development of tension pneumomediastinum and tension pneumothorax during ventilation. Neither the tension pneumomediastinum nor the tension pneumothorax were decompressed and accordingly resuscitation efforts remained unsuccessful. This case illustrates the need for a structured approach to resuscitate patients with ventilation problems regarding decompression of tension pneumomediastinum and/or tension pneumothorax during CPR.

    The objective of this prospective study was to assess the incidence and magnitude of fat emboli after cardiopulmonary resuscitation and intraosseous infusions. An animal laboratory at a university center was used to study 33 mixed-breed piglets. The piglets underwent hypoxic cardiac arrest followed by chest compressions and mechanical ventilation for a minimum of 30 minutes. The animals were divided in groups: group 1 (n = 5), which had no intraosseous cannulas, group 2 (n = 6), which had intraosseous cannulas with infusion, groups 3 (n = 6), 4 (n = 6), and 5 (n = 8), which had intraosseous cannulas with infusion of epinephrine, normal saline, and sodium bicarbonate respectively, and group 6 (n = 2), which was a sham group with no intraosseous cannulas and no cardiopulmonary resuscitation. At cessation of cardiopulmonary resuscitation, representative lung samples were collected from upper and lower lobes of each lung and observed for fat globules and bone marrow elements. Fat globules were seen in the peribronchial blood vessels and intravascular areas throughout all lung fields of groups 1 through 5. There was no difference in appearance or distribution of fat globules among the 5 treatment groups. Analysis of variance showed no statistical significance (P fat embolization over cardiopulmonary resuscitation alone in this animal model. The benefits of using this procedure in critically ill children as a means of rapid vascular access for resuscitation is well established. However, the risk of fat embolism in this population needs further study. PMID:9258208

    Multiple interventions have been tested in models of cardiopulmonary resuscitation (CPR) to optimize drug use, chest compressions, and ventilation. None has studied the effects of positive end-expiratory pressure (PEEP) on outcome. We hypothesized that because PEEP can reverse pulmonary atelectasis, lower pulmonary vascular resistance, and potentially improve cardiac output, its use during CPR would increase survival.

    At the present time, improvement of the system of medical care of cosmonauts is an important problem. For this reason, there are plans for development of a set of resuscitation measures that would be necessary in the case of onset of acute hypoxic and anoxic states, which may occur in sudden emergency situations. The purpose of the experiment was to examine the mechanism of transition from life to death on the molecular level. Renewal of proteins and nucleic acids, and change in their conformation (spatial arrangement) were used as the main indicators of changes in metabolic processes in case of death due to anoxic anoxia (exsanguination). With this procedure it was possible to reflect some patterns of biopolymer conversions related to processes of dying and resuscitation. Processes examined were the intensity of synthesis and dissociation of proteins and nucleic acids in the basic organs and tissues of experimental animals: different parts of the brain, myocardium and skeletal muscles, liver, kidneys, lung, spleen, adrenals, thyroid and pancreas, blood, bile and urine.

  6. Metabolic resuscitation in sepsis: a necessary step beyond the hemodynamic?

    2016-07-01

    Despite the advances made in monitoring and treatment of sepsis and septic shock, many septic patients ultimately develop multiple organ dysfunction (MODS) and die, suggesting that other players are involved in the pathophysiology of this syndrome. Mitochondrial dysfunction occurs early in sepsis and has a central role in MODS development. MODS severity and recovery of mitochondrial function have been associated with survival. In recent clinical and experimental investigations, mitochondrion-target therapy for sepsis and septic shock has been suggested to reduce MODS severity and mortality. This intervention, which might be named "metabolic resuscitation", would lead to improved mitochondrial activity afforded by pharmacological and nutritional agents. Of particular interest in this therapeutic strategy is thiamine, a water-soluble vitamin that plays an essential role in cellular energy metabolism. Critical illness associated with hypermetabolic states may predispose susceptible individuals to the development of thiamine deficiency, which is not usually identified by clinicians as a source of lactic acidosis. The protective effects of thiamine on mitochondrial function may justify supplementation in septic patients at risk of deficiency. Perspectives of supplementation with other micronutrients (ascorbic acid, tocopherol, selenium and zinc) and potential metabolic resuscitators [coenzyme Q10 (CoQ10), cytochrome oxidase (CytOx), L-carnitine, melatonin] to target sepsis-induced mitochondrial dysfunction are also emerging. Metabolic resuscitation may probably be a safe and effective strategy in the treatment of septic shock in the future. However, until then, preliminary investigations should be replicated in further researches for confirmation. Better identification of groups of patients presumed to benefit clinically by a certain intervention directed to "mitochondrial resuscitation" are expected to increase driven by genomics and metabolomics.

    Full Text Available Abstract Background The aim of the study was to evaluate the long-term outcome of patients successfully resuscitated from pre-hospital cardiac arrest with initial pulseless electrical activity (PEA, because the long-term outcome of these patients is unknown. Survival, neurological status one year after cardiac arrest and self-perceived quality of life after five years were assessed. Methods This retrospective study included adult patients resuscitated from PEA between August 2001 and March 2003 in three urban areas in southern Finland. A validated questionnaire was sent to patients while neurological status according to the Cerebral Performance Category (CPC -classification was assessed based on medical database notes recorded during follow-up evaluations. Results Out of 99 included patients in whom resuscitation was attempted, 41 (41% were successfully resuscitated and admitted to hospital. Ten (10% patients were discharged from hospital. Seven were alive after one year and six after five years following cardiac arrest. Five of the seven patients alive one year after resuscitation presented with the same functional level as prior to cardiac arrest. Conclusions Patients with initial PEA have been considered to have poor prognosis, but in our material, half of those who survived to hospital discharge were still alive after 5 years. Their self-assessed quality of life seems to be good with only mild to moderate impairments in activities of daily life.

    There are no national or international guidelines for the resuscitation of conjoined twins. We have described how the U.S. Neonatal Resuscitation Program algorithm can be modified for delivery room resuscitation of omphaloischiopagus conjoined twins. In planning for the delivery and resuscitation of these patients, we considered the challenges of providing cardiopulmonary support to preterm conjoined twins in face-to-face orientation and with shared circulation via a fused liver and single umbilical cord. We also demonstrate how in situ simulation can be used to prepare a large, multidisciplinary team of health care professionals to deliver safe, efficient, and effective care to such patients.

    Full Text Available In view of the importance of anticipating the occurrence of critical situations in medicine, we propose the use of a fuzzy expert system to predict the need for advanced neonatal resuscitation efforts in the delivery room. This system relates the maternal medical, obstetric and neonatal characteristics to the clinical conditions of the newborn, providing a risk measurement of need of advanced neonatal resuscitation measures. It is structured as a fuzzy composition developed on the basis of the subjective perception of danger of nine neonatologists facing 61 antenatal and intrapartum clinical situations which provide a degree of association with the risk of occurrence of perinatal asphyxia. The resulting relational matrix describes the association between clinical factors and risk of perinatal asphyxia. Analyzing the inputs of the presence or absence of all 61 clinical factors, the system returns the rate of risk of perinatal asphyxia as output. A prospectively collected series of 304 cases of perinatal care was analyzed to ascertain system performance. The fuzzy expert system presented a sensitivity of 76.5% and specificity of 94.8% in the identification of the need for advanced neonatal resuscitation measures, considering a cut-off value of 5 on a scale ranging from 0 to 10. The area under the receiver operating characteristic curve was 0.93. The identification of risk situations plays an important role in the planning of health care. These preliminary results encourage us to develop further studies and to refine this model, which is intended to implement an auxiliary system able to help health care staff to make decisions in perinatal care.

    A total of 75 patients with penetrating cardiac injuries were treated at Lincoln Medical and Mental Health Center from January, 1974, to November, 1980. Twenty-two patients (29.3%) were unconscious on arrival and had no detectable vital signs, cardiac activity, or spontaneous respirations. Their last physical movement was observed in the ambulance. Immediate resuscitation of these patients employing intercostal or sternal splitting incisions in the emergency room revealed arrested hearts and permitted relief of tamponade, finger occlusion of the cardiac wound or wounds, and temporary suturing of the defect. Restoration of cardiac function was accomplished in 16 patients (72.7%). After transfer to the operating room for more definitive cardiorrhaphy and repair of other major wounds, 8 patients (36.4%) recovered without objective neurological disability. Our experience clearly supports the value of immediate emergency room thoracotomy in this group of patients. PMID:7305523

    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 cardiac output. There is some evidence that HBOCs more efficiently unload oxygen from plasma hemoglobin as well as facilitate RBC unloading. We analyzed one volunteer study, 15 intraoperative trials, and 3 trauma studies using HBOCs. Perioperative studies generally suggest ability to deliver oxygen, but one trauma trial using HBOCs (HemAssist) for treatment of trauma resulted in a dramatic increase in mortality, while an intraoperative trauma study using Polyheme demonstrated reductions in 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

    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. PMID:26181002

    Full Text Available Abstract The primary treatment of hemorrhagic shock is control of the source of bleeding as soon as possible and fluid replacement. In controlled hemorrhagic shock (CHS where the source of bleeding has been occluded fluid replacement is aimed toward normalization of hemodynamic parameters. In uncontrolled hemorrhagic shock (UCHS in which bleeding has temporarily stopped because of hypotension, vasoconstriction, and clot formation, fluid treatment is aimed at restoration of radial pulse, or restoration of sensorium or obtaining a blood pressure of 80 mmHg by aliquots of 250 ml of lactated Ringer's solution (hypotensive resuscitation. When evacuation time is shorter than one hour (usually urban trauma immediate evacuation to a surgical facility is indicated after airway and breathing (A, B have been secured ("scoop and run". Precious time is not wasted by introducing an intravenous line. When expected evacuation time exceeds one hour an intravenous line is introduced and fluid treatment started before evacuation. Crystalloid solutions and blood transfusion are the mainstays of pre-hospital and in-hospital treatment of hemorrhagic shock. In the pre-hospital setting four types of fluid are presently recommended: crystalloid solutions, colloid solutions, hypertonic saline and oxygen-carrying blood substitutes. In unstable or unresponsive hemorrhagic shock surgical treatment is mandatory as soon as possible to control the source of bleeding.

    This review of early care covers issues pertaining to the analysis of system function, prehospital intravascular volume replacement, diagnosis of proximity vascular injury, the role of emergency thoracotomy, and the value of transesophageal echocardiography. The first six articles deal with various aspects of system function, from triage to analysis of outcome. The next series of articles reviews work in progress evaluating optimal fluid for resuscitation. Hypertonic saline and dextran combinations have been shown to restore vital signs better than isotonic solutions; they are safe, require smaller volumes, and may improve head injury outcome. Danger lies in the restoration of perfusion without hemorrhage control. Two articles on emergency thoracotomy review the indications and outcome in blunt and penetrating trauma. Survival in blunt trauma is virtually zero. An article and two editorials summarize state of the art for diagnosis and treatment of proximity vascular injury. Two articles describe the potential use of the new technique of transesophageal echocardiography. This new modality has not formed a solid indication at present and can be considered investigational in trauma care. PMID:7584006

    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

    Despite media images to the contrary, cardiopulmonary resuscitation in emergency departments is often unsuccessful. The purpose of this ethnographic study was to explore how health care professionals working in two emergency departments in the UK, make decisions to commence, continue or stop resuscitation. Data collection involved participant observation of resuscitation attempts and in-depth interviews with nurses, medical staff and paramedics who had taken part in the attempts. Detailed case examples were constructed for comparative analysis. Findings show that emergency department staff use experience and acquired tacit knowledge to construct a typology of cardiac arrest categories that help them navigate decision making. Categorisation is based on 'less is more' heuristics which combine explicit and tacit knowledge to facilitate rapid decisions. Staff then work as a team to rapidly assimilate and interpret information drawn from observations of the patient's body and from technical, biomedical monitoring data. The meaning of technical data is negotiated during staff interaction. This analysis was informed by a theory of 'bodily' and 'technical' trajectory alignment that was first developed from an ethnography of death and dying in intensive care units. The categorisation of cardiac arrest situations and trajectory alignment are the means by which staff achieve consensus decisions and determine the point at which an attempt should be withdrawn. This enables them to construct an acceptable death in highly challenging circumstances. PMID:27017090

    Emergency physicians and intensivists are increasingly utilizing capnography and bedside echocardiography during medical resuscitations. These techniques have shown promise in predicting outcomes in cardiac arrest, and no cases of return of spontaneous circulation in the setting of sonographic cardiac standstill and low end-tidal carbon dioxide have been reported. This case report illustrates an example of such an occurrence. Our aims are to report a case of return of spontaneous circulation ...

  3. Impact of increasing levels of advanced iterative reconstruction on image quality in low-dose cardiac CT angiography

    International Nuclear Information System (INIS)

    Purpose: To investigate the effects of an advanced iterative reconstruction (IR) technique on subjective and objective image quality (IQ) in low-dose cardiac CT angiography (CCTA). Materials and Methods: 30 datasets of prospectively triggered 'step-and-shoot' CCTA scans acquired on a 256-slice CT scanner with optimized exposure settings were processed on a prototype IR system using filtered back-projection (FBP) and 4 levels of advanced IR (iDose4, Philips) providing incremental rates of IR (level 2, 4, 6, 7). In addition, the effects of different reconstruction kernels (semi-smooth [CB], standard with edge-enhancement [XCB]) and a 'multi-resolution' feature [MR] to preserve the noise power spectrum were evaluated resulting in a total of n = 480 image sets. Contrast-to-noise ratios (CNR) were computed from regions of interest at 9 coronary locations. The subjective IQ was rated on a 4-point-scale with 'classic' image appearance and noise-related artifacts as main criteria. Results: At an effective dose of 1.7 ± 0.7 mSv, the CNR significantly improved with every increasing level of IR (range: 14.2-27.8; p < 0.001) with the best objective IQ at the highest level of IR (level 7). The subjective IQ, however, was rated best at the medium level of IR (level 4) with minimal artifacts and a more 'classic' image appearance when compared to higher IR levels. The XCB kernel provided better subjective ratings than CB (p < 0.05) and the MR feature further increased the IQ at a high level of IR. Conclusion: The objective IQ of low-dose CCTA progressively improves with an increasing level of IR. The best subjective IQ, however, is reached at medium levels of IR combined with an edge-enhancing kernel allowing for preservation of a 'classic' image appearance suggesting application in the clinical routine.

    Advanced heart failure (HF) is the leading cause of death in developed countries. The mechanism underlying the progression of cardiac dysfunction needs to be clarified to establish approaches to prevention or treatment. Here, using TO-2 hamsters with hereditary dilated cardiomyopathy, we show age-dependent cleavage and translocation of myocardial dystrophin (Dys) from the sarcolemma (SL) to the myoplasm, increased SL permeability in situ, and a close relationship between the loss of Dys and h...

    Endotracheal aspiration protocols (EAT) include hyperoxygenation and hyperinflation to minimize the negative effects of the technique. No conclusive studies have determined the most effective hyperoxygenation and hyperinflation method. This study had two aims: to compare the effects on patient oxygenation and hemodynamics during endotracheal aspiration of secretions using, respectively, a respirator or manual resuscitator as the hyperoxygenation and hyperinflation method. Tidal volume (TV) and FIO2 with the manual resuscitator were quantified. The study was based on 172 aspiration sessions carried out under artificial ventilation in the immediate postoperative period of 26 patients who had undergone cardiac surgery without lung damage. Hyperinflation and hyperoxygenation before, during and after aspiration were carried out with and artificial ventilator in group I and with a manual resuscitator in group II. In all aspiration interventions, an analysis was made of hemodynamic parameters (MAP, MPAP, HR, CO and arrhythmias), ventilation and oxygenation parameters (HR, FIO2, SpO2, and SvO2), and the influence of the method on the appearance of atelectasis. Both methods produced small increases in all hemodynamic parameters, and significant differences in HR (p < 0.001) and MPAP (p < 0.002), although no clinical repercussions were observed. No severe arrhythmias were observed. No statistically significant differences between the two methods were found in the evolution of SpO2 and SvO2, which remained above baseline levels throughout both procedures. Analysis of the effectiveness of the manual resuscitator (the second aim) under the conditions established yielded a mean FIO2 of 0.86 and a mean tidal volume of 153% in relation to baseline tidal volume. Both methods of hyperoxygenation and hyperinflation prevent hypoxia and maintain hemodynamic stability in patients without producing lung damage.

    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 <0.001). The proportion of patients who died during the arrest was 12.5% in those who received epinephrine alone, 30.0% in those who received only epinephrine and bicarbonate, and 46.7% to 57.9% in the remaining groups. Patients receiving only epinephrine had shorter resuscitation durations compared to that of the other groups (p <0.001) and improved survival (p = 0.003). In conclusion, providers frequently use nonguideline medications in 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. PMID:27015887

    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. PMID:25656720

  12. Coronary blood flow during cardiopulmonary resuscitation in swine

    International Nuclear Information System (INIS)

    Recent papers have raised doubt as to the magnitude of coronary blood flow during closed-chest cardiopulmonary resuscitation. We will describe experiments that concern the methods of coronary flow measurement during cardiopulmonary resuscitation. Nine anesthetized swine were instrumented to allow simultaneous measurements of coronary blood flow by both electromagnetic cuff flow probes and by the radiomicrosphere technique. Cardiac arrest was caused by electrical fibrillation and closed-chest massage was performed by a Thumper (Dixie Medical Inc., Houston). The chest was compressed transversely at a rate of 66 strokes/min. Compression occupied one-half of the massage cycle. Three different Thumper piston strokes were studied: 1.5, 2, and 2.5 inches. Mean aortic pressure and total systemic blood flow measured by the radiomicrosphere technique increased as Thumper piston stroke was lengthened (mean +/- SD): 1.5 inch stroke, 23 +/- 4 mm Hg, 525 +/- 195 ml/min; 2 inch stroke, 33 +/- 5 mm Hg, 692 +/- 202 ml/min; 2.5 inch stroke, 40 +/- 6 mm Hg, 817 +/- 321 ml/min. Both methods of coronary flow measurement (electromagnetic [EMF] and radiomicrosphere [RMS]) gave similar results in technically successful preparations (data expressed as percent prearrest flow mean +/- 1 SD): 1.5 inch stroke, EMF 12 +/- 5%, RMS 16 +/- 5%; 2 inch stroke, EMF 30 +/- 6%, RMS 26 +/- 11%; 2.5 inch stroke, EMF 50 +/- 12%, RMS 40 +/- 20%. The phasic coronary flow signal during closed-chest compression indicated that all perfusion occurred during the relaxation phase of the massage cycle. We concluded that coronary blood flow is demonstrable during closed-chest massage, but that the magnitude is unlikely to be more than a fraction of normal

    "Organ preserving cardiopulmonary resuscitation (OP-CPR)" is defined as the use of CPR in cases of cardiac arrest to preserve organs for transplantation, rather than to revive the patient. Is it ethical to provide OP-CPR in a brain-dead organ donor to save organs that would otherwise be lost? To answer this question, we review the literature on brain-dead organ donors, conduct an ethical analysis, and make recommendations. We conclude that OP-CPR can benefit patients and families by fulfilling the wish to donate. However, it is an aggressive procedure that can cause physical damage to patients, and risks psychological harm to families and healthcare professionals. In a brain-dead organ donor, OP-CPR is acceptable without specific informed consent to OP-CPR, although advance discussion with next of kin regarding this possibility is strongly advised. In a patient where brain death is yet to be determined, but there is known wish for organ donation, OP-CPR would only be acceptable with a specific informed consent from the next of kin. When futility of treatment has not been established or it is as yet unknown if the patient wished to be an organ donor then OP-CPR should be prohibited, in order to avoid any conflict of interest.

    Objective: To measure end-tidal carbon dioxide pressure (PetCO2) in preset interval in order to evaluate the efficiency of cardiopulmonary resuscitation (CPR) performed on patients in cardiopulmonary arrest, evaluate the validity of PetCO2 in predicting the mortality and finally assess the PetCO2 levels of the patients in cardiopulmonary arrest based on the initial presenting rhythm. Methods: This prospective study was conducted at the Ankara Training and Research Hospital on patients who presented with cardiopulmonary arrest. Standard ACLS (Advanced Cardiac Life Support) protocols were performed. Patients were categorized in two groups based on their rhythms as Ventricular Fibrillation and Asystole. Patients’ PetCO2 values were recorded. Results: PetCO2 levels of the Return of Spontaneous Circulation (ROSC) group in the 5th, 10th, 15th and 20th minutes were significantly higher compared to the exitus group (p<0.001). In distinguishing ROSC and exitus, PetCO2 measurements within 5-20 minute intervals showed highest performance on the 20th and lowest on the 5th minutes. Conclusion: PetCO2 values are higher in the ROSC group. During the CPR, the most reliable time for ROSC estimation according to PetCO2 values is 20th minute. None of the patients who had PetCO2 levels less than 14 mmHg survived. PMID:24639823

    Full Text Available Context: Cardiopulmonary resuscitation (CPR and emergency cardiovascular care guidelines are periodically renewed and published by the American Heart Association. Formal training programs are conducted based on these guidelines. Despite widespread training CPR is often poorly performed. Hospital educators spend a significant amount of time and money in training health professionals and maintaining basic life support (BLS and advanced cardiac life support (ACLS skills among them. However, very little data are available in the literature highlighting the long-term impact of these training. Aims: To evaluate the impact of formal certified CPR training program on the knowledge and skill of CPR among nurses, to identify self-reported outcomes of attempted CPR and training needs of nurses. Setting and Design : Tertiary care hospital, Prospective, repeated-measures design. Subjects and Methods: A series of certified BLS and ACLS training programs were conducted during 2010 and 2011. Written and practical performance tests were done. Final testing was undertaken 3-4 years after training. The sample included all available, willing CPR certified nurses and experience matched CPR noncertified nurses. Statistical Analysis Used: SPSS for Windows version 21.0. Results: The majority of the 206 nurses (93 CPR certified and 113 noncertified were females. There was a statistically significant increase in mean knowledge level and overall performance before and after the formal certified CPR training program (P = 0.000. However, the mean knowledge scores were equivalent among the CPR certified and noncertified nurses, although the certified nurses scored a higher mean score (P = 0.140. Conclusions: Formal certified CPR training program increases CPR knowledge and skill. However, significant long-term effects could not be found. There is a need for regular and periodic recertification.

    Full Text Available Carbon dioxide (CO2 embolism is a rare but potentially fatal complication of laparoscopic surgery. We report a case of presumed CO2 embolism in a 35-year-old female during laparoscopic ureteric reconstructive surgery. After 2 h of operating time, a sudden decrease in end-tidal carbon dioxide and deterioration of hemodynamic status followed by cardiac arrest with pulseless electrical activity suggested gas embolism. Immediate cardiopulmonary resuscitation and inotropic support resulted in successful outcome. Thus, early recognition of the complication and prompt treatment can avoid catastrophy.

    Full Text Available Neurologic outcomes following pediatric cardiac arrest are consistently poor. Early initiation of cardiopulmonary resuscitation has been shown to have positive effects on both survival to hospital discharge, and improved neurological outcomes after cardiac arrest. Additionally, the use of therapeutic hypothermia may improve survival in pediatric cardiac arrest patients admitted to the intensive care unit. We report a child with congenital hypertrophic obstructive cardiomyopathy and an out-of-hospital cardiac arrest, in whom the early initiation of effective prolonged cardiopulmonary resuscitation and subsequent administration of therapeutic hypothermia contributed to a positive outcome with no gross neurologic sequelae. Continuing efforts should be made to promote and employ high-quality cardiopulmonary resuscitation, which likely contributed to the positive outcome of this case. Further research will be necessary to develop and solidify national guidelines for the implementation of therapeutic hypothermia in selected subpopulations of children with OHCA.

    ApoE/LDLR(-/-) mice represent a reliable model of atherosclerosis. However, it is not clear whether cardiac performance is impaired in this murine model of atherosclerosis. Here, we used MRI to characterize cardiac performance in vivo in apoE/LDLR(-/-) mice with advanced atherosclerosis. Six-month-old apoE/LDLR(-/-) mice and age-matched C57BL/6J mice (control) were examined using highly time-resolved cine-MRI [whole-chamber left ventricle (LV) imaging] and MR tagging (three slices: basal, mid-cavity and apical). Global and regional measures of cardiac function included LV volumes, kinetics, time-dependent parameters, strains and rotations. Histological analysis was performed using OMSB (orceine with Martius, Scarlet and Blue) and ORO (oil red-O) staining to demonstrate the presence of advanced coronary atherosclerosis. MR-tagging-based strain analysis in apoE/LDLR(-/-) mice revealed an increased frequency of radial and circumferential systolic stretch (25% and 50% of segments, respectively, p ≤ 0.012), increased radial post-systolic strain index (45% of segments, p = 0.009) and decreased LV untwisting rate (-30.3° (11.6°)/cycle, p = 0.004) when compared with control mice. Maximal strains and LV twist were unchanged. Most of the cine-MRI-based LV functional and anatomical parameters also remained unchanged in apoE/LDLR(-/-) mice, with only a lower filling rate, longer filling time, shorter isovolumetric contraction time and slower heart rate observed in comparison with control mice. The coronary arteries displayed severe atherosclerosis, as evidenced by histological analysis. Using comprehensive MRI methods, we have demonstrated that, despite severe coronary atherosclerosis in six-month-old apoE/LDLR(-/-) mice, cardiac performance including global parameters, twist and strains, was well preserved. Only subtle diastolic alterations, possibly of ischemic background, were uncovered. Copyright © 2016 John Wiley & Sons, Ltd. PMID:27146203

  4. Role of external cardiac compression in truncal trauma.

    External cardiac compression (ECC) was originally developed for patients with nontraumatic cardiac conditions, but it is now used for a wide variety of emergency conditions. As an integral part of cardiopulmonary resuscitation (CPR), ECC coupled with forced pulmonary ventilation may NOT be applicable to cases of cardiac arrest following penetrating and blunt thoracic and abdominal trauma. Review of 100 patients with penetrating or blunt truncal trauma who received CPR and ECC more than 3 minutes prehospital revealed NO survivors despite continued aggressive resuscitative efforts in 49 of the patients upon arrival at a trauma center. Major cardiovascular disruption was found at thoracotomy or autopsy in all patients. In another 12 patients receiving forced ventilation and prehospital ECC, air embolism to the coronary arteries was the cause of death. CPR by paramedics, physicians, nurses, or lay persons does not appear to be of value in patients who have sustained cardiac arrest from truncal trauma. PMID:7143499

  5. External cardiac compression may be harmful in some scenarios of pulseless electrical activity.

    Pulseless electrical activity occurs when organised or semi-organised electrical activity of the heart persists but the product of systemic vascular resistance and the increase in systemic arterial flow generated by the ejection of the left venticular stroke volume is not sufficient to produce a clinically detectable pulse. Pulseless electrical activity encompasses a very heterogeneous variety of severe circulatory shock states ranging in severity from pseudo-cardiac arrest to effective cardiac arrest. Outcomes of cardiopulmonary resuscitation for pulseless electrical activity are generally poor. Impairment of cardiac filling is the limiting factor to cardiac output in many scenarios of pulseless electrical activity, including extreme vasodilatory shock states. There is no evidence that external cardiac compression can increase cardiac output when impaired cardiac filling is the limiting factor to cardiac output. If impaired cardiac filling is the limiting factor to cardiac output and the heart is effectively ejecting all the blood returning to it, then external cardiac compression can only increase cardiac output if it increases venous return and cardiac filling. Repeated cardiac compression asynchronous with the patient\\'s cardiac cycle and raised mean intrathoracic pressure due to chest compression can be expected to reduce rather than to increase cardiac filling and therefore to reduce rather than to increase cardiac output in such circumstances. The hypothesis is proposed that the performance of external cardiac compression will have zero or negative effect on cardiac output in pulseless electrical activity when impaired cardiac filling is the limiting factor to cardiac output. External cardiac compression may be both directly and indirectly harmful to significant sub-groups of patients with pulseless electrical activity. We have neither evidence nor theory to provide comfort that external cardiac compression is not harmful in many scenarios of pulseless

    Full Text Available Introduction: Echocardiography or cardiac imaging is proposed as a gold standard method for identifying high risk patients for cardiac arrest. In this systematic review, we studied the prognostic value of cardiac sonography in patients with cardiac arrest. Methods: PubMed was searched for the relevant articles. Case reports were not included. Inclusion criteria were all the studies applied transthorasic echocardiography in patients with cardiac arrest arrived at emergency department that studied the efficacy of this modality on patients survived to emergency discharge and returned to spontaneous circulation.Result: Overall, 870 articles were obtained through initial search and only nine articles were included after the evaluation of the title, abstract, and the full text. Echocardiography has high sensitivity and specificity in predicting the return of spontaneous circulation.Conclusion: Cardiac sonography is a fairly effective (not definitive modality in predicting death in patients with lack of cardiac activity during resuscitation. Echocardiography should not be the sole basis for the decision to cease resuscitative efforts.

    This book covers the main mathematical and numerical models in computational electrocardiology, ranging from microscopic membrane models of cardiac ionic channels to macroscopic bidomain, monodomain, eikonal models and cardiac source representations. These advanced multiscale and nonlinear models describe the cardiac bioelectrical activity from the cell level to the body surface and are employed in both the direct and inverse problems of electrocardiology. The book also covers advanced numerical techniques needed to efficiently carry out large-scale cardiac simulations, including time and space discretizations, decoupling and operator splitting techniques, parallel finite element solvers. These techniques are employed in 3D cardiac simulations illustrating the excitation mechanisms, the anisotropic effects on excitation and repolarization wavefronts, the morphology of electrograms in normal and pathological tissue and some reentry phenomena. The overall aim of the book is to present rigorously the mathematica...

    2015-08-01

    Cardiac arrest can occur in any health care setting at any time, requiring nursing staff to be prepared to quickly and adequately perform basic cardiopulmonary resuscitation (CPR). Currently, the American Heart Association certifies health care providers in Basic Life Support (BLS) for a 2-year period, but evidence indicates that psychomotor skills decline well before the end of the certification time frame. Nurses in the ambulatory surgery setting expressed concern regarding their ability to implement CPR successfully, given the infrequent occurrence of cardiac and respiratory arrests. Using a study by Niles et al. as a model, the authors piloted the implementation of brief CPR refresher training at the bedside of an ambulatory surgery center to assess and increase nurse confidence in BLS skills.

    Our objective was to estimate the saving of life by thrombolysis and resuscitation in acute myocardial infarction (AMI) before and after hospital admission. We studied all 1516 patients admitted to a Scottish teaching hospital in 1990 and 1992 who had a final diagnosis of AMI, and 311 patients enrolled in the Grampian region early anistreplase trial (GREAT). Cardiac arrest occurred in 250/1516 (16%) hospital patients. Of these, 77 (31%) were discharged alive--a saving of 51 lives per thousand cases. 797 (53%) patients received thrombolysis, of whom 114 (14%) died. Assuming the same relative reduction in mortality as in the second international study of infarct survival (ISIS-2; 23%), 34 lives were saved by thrombolytic therapy, representing 22 lives per thousand cases. Of 311 patients in GREAT, 15 (5%) had prehospital cardiac arrest, with 7 patients surviving to discharge (48%)--a saving of 23 lives per thousand cases. Those patients given domiciliary thrombolysis had a one month mortality of 6.7% (11/163) compared with 12.2% (18/148) for those receiving hospital thrombolysis--a saving of 55 lives per thousand cases for prehospital thrombolysis. This is additional to 28 lives per thousand estimated for thrombolytic therapy in hospital, totalling 83 lives saved per thousand cases of AMI receiving thrombolytic therapy prehospital. In hospital, more lives were saved by resuscitation than by thrombolytic therapy, but this ratio was reversed in the period before hospital admission. These results emphasise the paramount importance of resuscitation in hospital, and the enhanced efficacy of thrombolysis when given at the earliest opportunity. PMID:7607764

    Recognizing and responding to a cardiac arrest in the hospital setting is a high stress, high anxiety event for all healthcare providers. It requires the performance of several basic, but extremely important cardiopulmonary resuscitation (CPR) skills and response priorities. If not executed correctly and in a timely manner, a bad outcome may result. Poor retention of cardiopulmonary resuscitation skills and priorities is well documented in the literature. An integrative review of the evidence was conducted to answer the question, "Is there a more effective training method to improve nurses' retention of CPR priorities during an in hospital cardiac arrest as compared to traditional American Heart Association training? "This review evaluated high fidelity and low fidelity simulation training, online or computer-based training and video instruction as potential teaching strategies focusing on CPR priorities. The role of deliberate practice is discussed. The strongest evidence suggests that a teaching plan employing brief, frequent, repetitive or deliberate practice used in collaboration with low fidelity or high fidelity simulation may be a potential strategy to improve nurses' retention of CPR priorities over time.

    To find out the optimal concentration, infusion rate and dosage of saline for resuscitation. Methods: Forty-five dogs were used to establish hypovolemic shock models. The dogs were resuscitated with saline of different concentrations and different dosages under different infusion rates, and the resuscitation results were compared. Results: The best concentration was 7.5%, the best rate of infusion 20 ml/min (a volume equivalent to 15% of the shed blood) and the best dosage 5.71 ml/kg. The method was effective for resuscitation, the mean arterial pressure (MAP) could be elevated to 89% of the baseline, and this MAP could be kept for more than one hour. Conclusions: Using 7.5% sodium chloride solution equivalent to 15% of the shed blood at an infusion rate of 20 ml/min can achieve a best resuscitation result.

    Full Text Available Clinically relevant animal models capable of simulating traumatic hemorrhagic shock are needed. We developed a hemorrhagic shock model with male New Zealand rabbits (2200-2800 g, 60-70 days old that simulates the pre-hospital and acute care of a penetrating trauma victim in an urban scenario using current resuscitation strategies. A laparotomy was performed to reproduce tissue trauma and an aortic injury was created using a standardized single puncture to the left side of the infrarenal aorta to induce hemorrhagic shock similar to a penetrating mechanism. A 15-min interval was used to simulate the arrival of pre-hospital care. Fluid resuscitation was then applied using two regimens: normotensive resuscitation to achieve baseline mean arterial blood pressure (MAP, 10 animals and hypotensive resuscitation at 60% of baseline MAP (10 animals. Another 10 animals were sham operated. The total time of the experiment was 85 min, reproducing scene, transport and emergency room times. Intra-abdominal blood loss was significantly greater in animals that underwent normotensive resuscitation compared to hypotensive resuscitation (17.1 ± 2.0 vs 8.0 ± 1.5 mL/kg. Antithrombin levels decreased significantly in normotensive resuscitated animals compared to baseline (102 ± 2.0 vs 59 ± 4.1%, sham (95 ± 2.8 vs 59 ± 4.1%, and hypotensive resuscitated animals (98 ± 7.8 vs 59 ± 4.1%. Evidence of re-bleeding was also noted in the normotensive resuscitation group. A hypotensive resuscitation regimen resulted in decreased blood loss in a clinically relevant small animal model capable of reproducing hemorrhagic shock caused by a penetrating mechanism.

    Emergency center thoracotomy was performed at our facility on 389 patients from 1984 through 1989. There were no patients excluded from the study, and survival for all patients was 8.3% with survival rates of 15.2% and 7.3% for stab and gunshot wounds, respectively. Emergency center thoracotomy was performed on 42 patients suffering from isolated extrathoracic injuries with 7% survival. There were no survivors of blunt trauma in this study. Fifty-three percent of the patients arrived with cardiopulmonary resuscitation (CPR) in progress. The average time of prehospital CPR for survivors was 5.1 minutes compared with 9.1 minutes for nonsurvivors. Of the survivors, prehospital endotracheal intubation prolonged successful toleration of CPR to 9.4 minutes compared with 4.2 minutes for nonintubated surviving patients (p less than 0.001). Emergency center thoracotomy is useful in the resuscitation of victims dying of penetrating truncal trauma. Prehospital endotracheal intubation significantly lengthened the time of successful CPR.

According to the updated guidelines, the greatest efficacy in cardiac massage is only achieved when the right compression point, an adequate compression depth, vertical pressure, the correct frequency, and equally long phases of compression and decompression are achieved. The very highest priority is placed on restoring continuous circulation. Against this background, standardized continuous chest compression with active decompression has contributed to a favorable outcome in this case. The hydraulically operated and variably adjustable automatic Lund University Cardiac Arrest System (LUCAS device (Jolife, Lund, Sweden undoubtedly meets these requirements. This case report describes a 44-year-old patient who – approximately 15 min after the onset of clinical death due to apparent ventricular fibrillation – received cardiopulmonary resuscitation, initially by laypersons and then by the emergency medical team (manual chest compressions followed by situation-adjusted LUCAS compressions. Sinus rhythm was restored after more than 90 min of continuous resuscitation, with seven defibrillations. Interventional diagnostic workup did not reveal a causal morphological correlate for the condition on coronary

    Full Text Available Although emergency resuscitative thoracotomy is performed as a salvage maneuver for critical blunt trauma patients, evidence supporting superior effectiveness of emergency resuscitative thoracotomy compared to conventional closed-chest compressions remains insufficient. The objective of this study was to investigate whether emergency resuscitative thoracotomy at the emergency department or in the operating room was associated with favourable outcomes after blunt trauma and to compare its effectiveness with that of closed-chest compressions.This was a retrospective nationwide cohort study. Data were obtained from the Japan Trauma Data Bank for the period between 2004 and 2012. The primary and secondary outcomes were patient survival rates 24 h and 28 d after emergency department arrival. Statistical analyses were performed using multivariable generalized mixed-effects regression analysis. We adjusted for the effects of different hospitals by introducing random intercepts in regression analysis to account for the differential quality of emergency resuscitative thoracotomy at hospitals where patients in cardiac arrest were treated. Sensitivity analyses were performed using propensity score matching.In total, 1,377 consecutive, critical blunt trauma patients who received cardiopulmonary resuscitation in the emergency department or operating room were included in the study. Of these patients, 484 (35.1% underwent emergency resuscitative thoracotomy and 893 (64.9% received closed-chest compressions. Compared to closed-chest compressions, emergency resuscitative thoracotomy was associated with lower survival rate 24 h after emergency department arrival (4.5% vs. 17.5%, respectively, P < 0.001 and 28 d after arrival (1.2% vs. 6.0%, respectively, P < 0.001.

    Full Text Available Despite efforts to save more people suffering from in-hospital cardiac arrest, rates of survival after in-hospital cardiopulmonary resuscitation (CPR are no better today than they were more than a decade ago. This study was undertaken to assess the demographics, clinical parameters and outcomes of patients undergoing CPR by the code blue team at our center during 2001 to 2008. Data were collected retrospectively from adult patients (n=2262 who underwent CPR. Clinical outcomes of interest were survival at the end of CPR and survival at discharge from the hospital. Factors associated with survival were evaluated using binomial and Chi Square tests. Of the patients included (n=2262, 741 patients (32.8% had successful CPR. The number of male patients requiring CPR was more than females in need of the procedure. The majority of patients requiring CPR were older than 60 years (56.4±17.9. The number of successful CPR cases in long-day shift (7:00 to 19:00 was more than that in the night shift (19:00 to 7:00. Furthermore, 413 (18.4% cases were resuscitated on holidays and 1849 (81.7% on the working days. The duration of CPR was 10 min or less in 710 (31.4% cases. Cardiopulmonary resuscitations which lasted less than 10 minutes were associated with better outcomes. The findings of the present study indicate that some manageable factors including the duration of CPR, working shift, working day (holiday or non-holiday could affect the CPR outcomes. The findings might also be taken as evidence to suggest that the allocation of more personnel in each shift especially in night shifts and holidays, planning to increase the personnel's CPR skills, and decreasing the waste time would result in the improvement of CPR outcome.

    Full Text Available Sudden cardiac arrest is one of the leading causes of death in Europe. Bystanders’ early Cardio-Pulmonary Resuscitation (CPR may double or triple survival rates of out-of-hospital cardiac arrest victims. Aim: To investigate nurses’ attitude, in starting or not CPR and also the most frequent reasons that deter them from engaging in. Materials and Methods: The study had a sample of 177 nurses and assistant nurses that were working in nine hospitals of Athens. Nurses filled out the same, predetermined questionnaire, voluntarily and anonymously. The collected answers were analyzed with the help of the statistical program SPSS v.16, using x2 and Kendall’s Tau-B methods. Results: From 177 participants, 78% (137 were women and 22% (40 men with mean age 31 years (±7. According to their education, 16% (28 were Assistant Nurses, 79% (140 Registered Nurses (ATEI, AEI and 5% (9 Nurses had an MSc diploma. Nurses that had been recently trained in certified BLS courses felt more confident and were more willing to start CPR in a known victim (p=0.004 and in an unknown victim (p=0.02 comparing to nurses that had been trained a long time ago or never. Most frequent reasons nurses reported that deter them from starting CPR are the fear of a possible lawsuit (43%, the fear of harming instead of helping (30% and the fear of infectious transmission from victim to rescuer (15%. The fear of harming correlates considerably with lower ages (the younger the nurse the more is afraid, p=0.04 and also correlates substantially with the training in a certified CPR course (the more a nurse is trained, the less is afraid, p<0.001. Accordingly, the fear of infection diminishes as long as the CPR training is repeated (p=0.03. Conclusions: According to the results, there is a necessity of continuous education and re-education of nurses, in certified Basic Life Support programs. With frequent and specialized training, nurses will show more willingness to engage in an out

    Out-of-hospital cardiac arrest is common and patients who are initially resuscitated by ambulance officers and transported to hospital are usually admitted to the intensive care unit (ICU). In the past, the treatment in the ICU consisted of supportive care only, and most patients remained unconscious due to the severe anoxic neurological injury. It was this neurological injury rather than cardiac complications that caused the high rate of morbidity and mortality. However, in the early 1990's, a series of animal experiments demonstrated convincingly that mild hypothermia induced after return of spontaneous circulation and maintained for several hours dramatically reduced the severity of the anoxic neurological injury. In the mid-1990's, preliminary human studies suggested that mild hypothermia could be induced and maintained in post-cardiac arrest patients without an increase in the rate of cardiac or other complications. In the late 1990's, two prospective, randomised, controlled trials were conducted and the results confirmed the animal data that mild hypothermia induced after resuscitation and maintained for 12 - 24 hours dramatically improved neurological and overall outcomes. On the basis of these studies, mild hypothermia was endorsed in 2003 by the International Liaison Committee on Resuscitation as a recommended treatment for comatose patients with an initial cardiac rhythm of ventricular fibrillation. However, the application of this therapy into routine clinical critical care practice has been slow. The reasons for this are uncertain, but may relate to the relative complexity of the treatment, unfamiliarity with the pathophysiology of hypothermia, lack of clear protocols and/or uncertainty of benefit in particular patients. Therefore, recent research in this area has focused on the development of feasible, inexpensive techniques for the early, rapid induction of mild hypothermia after cardiac arrest. Currently, the most promising strategy is a rapid

    Background Coma after cardiopulmonary resuscitation (CPR) is commonly seen in daily clinical practice. How to objectively evaluate brain function after CPR is essential to the following treatment. Coma patients after CPR had been studied prospectively at the Neuro-Intensive Care Unit of Xuanwu Hospital since 2002. In this study, we focused on the topic of how to evaluate the severity of coma after CPR .Methods From April 2002 to November 2004, patients in coma 24 hours after CPR were monitored, the evaluation methods included Glasgow coma score (GCS),brain stem reflection, and spinal reflection. Laboratory evaluation included electroencephalography (EEG),brainstem auditory evoked potential (BAEP), short latency somatosensory evoked potential (SLSEP), and transcranial Doppler (TCD) .Results Twenty-four of 35 patients(68.57%)were in deep coma. The GCS was 3 except for 2 patients;EEG was evaluated not less than grade Ⅳ except for 4 patients, BAEP was evaluated as grade Ⅲ except for 3 patients, and SLSEP was evaluated as grade Ⅲ except for 1 patient.Twenty-four patients died within 1 month and 11 of them(45.83%)were determined as brain death. Glasgow outcome score (GOS) was evaluated as grade Ⅰ. Eleven of the 35 patients survived and their consciousness changed from deep coma to coma vigil. EEG was evaluated as gradeⅠin 5 patients, BAEP and SLSEP were evaluated as grade Ⅰ in 3 patients, and GOS was all evaluated as grade Ⅱ among the 11 patients.Two patients(18.18%)regained consciousness in 35 and 90 days after cardiopulmonary resuscitation and GOS was evaluated as grade Ⅳ and Ⅲ, respectively.Conclusion Combined or continuous evaluation of clinical examinations and laboratory tests can accurately and objectively determine brain function after CPR.

    Full Text Available Objective: Important studies of cardiopulmonary resuscitation (CPR techniques influence the development of new guidelines. We systematically reviewed the efficacy of some important studies of CPR. Data Sources: The data analyzed in this review are mainly from articles included in PubMed and EMBASE, published from 1964 to 2014. Study Selection: Original articles and critical reviews about CPR techniques were selected for review. Results: The survival rate after out-of-hospital cardiac arrest (OHCA is improving. This improvement is associated with the performance of uninterrupted chest compressions and simple airway management procedures during bystander CPR. Real-time feedback devices can be used to improve the quality of CPR. The recommended dose, timing, and indications for adrenaline (epinephrine use may change. The appropriate target temperature for targeted temperature management is still unclear. Conclusions: New studies over the past 5 years have evaluated various aspects of CPR in OHCA. Some of these studies were high-quality randomized controlled trials, which may help to improve the scientific understanding of resuscitation techniques and result in changes to CPR guidelines.

    Ventricular fibrillation (VF) is observed as the initial rhythm in the majority of patients suffering from sudden cardiac arrest. It is vitally important to accurately recognize the initial VF rhythm and then implement electrical defibrillation. However, artifacts produced by chest compression during cardiopulmonary resuscitation (CPR) make the VF detection algorithms utilized by current automated external defibrillators (AEDs) unreliable. CPR must be traditionally interrupted for a reliable diagnosis. However, interruptions in chest compression have a deleterious effect on the success of defibrillation. The elimination of the CPR artifacts would enable compressions to continue during AED VF detection and thereby increase the likelihood of resuscitation success. We have estimated a model of this artifact by adaptively incorporating noise-assisted multivariate empirical mode decomposition (NA-MEMD) and least mean squares (LMS) and then removing the artifact from the corrupted ECGs. The simulation experiment indicated that the CPR artifact could be accurately modeled without any reference channels. We constructed a BP neural network to evaluate the results. A total of 372 VF and 645 normal sinus rhythm (SR) ECG samples were included in the analysis, and 24 CPR artifact signals were used to construct corrupted ECGs. The results indicated that at different SNR levels ranging from 0 to -12 dB, the sensitivity and specificity were always above 95 and 80 %, respectively. PMID:26831488

    An improved pre-clinical cardiac chemical exchange saturation transfer (CEST) pulse sequence (cardioCEST) was used to selectively visualize paramagnetic CEST (paraCEST)-labeled cells following intramyocardial implantation. In addition, cardioCEST was used to examine the effect of diet-induced obesity upon myocardial creatine CEST contrast. CEST pulse sequences were designed from standard turbo-spin-echo and gradient-echo sequences, and a cardiorespiratory-gated steady-state cine gradient-echo sequence. In vitro validation studies performed in phantoms composed of 20mM Eu-HPDO3A, 20mM Yb-HPDO3A, or saline demonstrated similar CEST contrast by spin-echo and gradient-echo pulse sequences. Skeletal myoblast cells (C2C12) were labeled with either Eu-HPDO3A or saline using a hypotonic swelling procedure and implanted into the myocardium of C57B6/J mice. Inductively coupled plasma mass spectrometry confirmed cellular levels of Eu of 2.1 × 10−3 ng/cell in Eu-HPDO3A-labeled cells and 2.3 × 10−5 ng/cell in saline-labeled cells. In vivo cardioCEST imaging of labeled cells at ±15ppm was performed 24 h after implantation and revealed significantly elevated asymmetric magnetization transfer ratio values in regions of Eu-HPDO3A-labeled cells when compared with surrounding myocardium or saline-labeled cells. We further utilized the cardioCEST pulse sequence to examine changes in myocardial creatine in response to diet-induced obesity by acquiring pairs of cardioCEST images at ±1.8 ppm. While ventricular geometry and function were unchanged between mice fed either a high-fat diet or a corresponding control low-fat diet for 14 weeks, myocardial creatine CEST contrast was significantly reduced in mice fed the high-fat diet. The selective visualization of paraCEST-labeled cells using cardioCEST imaging can enable investigation of cell fate processes in cardioregenerative medicine, or multiplex imaging of cell survival with imaging of cardiac structure and function and

    Despite years of research on the resuscitation of the patient with critical traumatic injuries, controversy remains surrounding the criteria to waive initiation of resuscitation in the pre-hospital setting or to terminate such efforts in the emergency department. The decision to initiate or continue resuscitation on moribund trauma patients is associated with considerable costs. Ambulance transport using lights and sirens carries potential risk. Emergency department thoracotomy, with exposure to high risk bodily fluids, involvement of numerous staff, and usage precious blood products, is a procedure that has fewer and fewer indications. This review presents guidelines to help determine when to initiate resuscitation for the critically injured trauma patient and when to cease these efforts in the emergency department. Since there are economic, societal, and ethical implications, each system should establish their own criteria, using these guidelines as a basis. PMID:11805549

    Despite advances in neonatal care, the rate of oxygen dependence at 36 weeks\\' postmenstrual age or bronchopulmonary dysplasia has not fallen. Neonatologists are increasingly careful to apply ventilation strategies that are gentle to the lung in the neonatal intensive care unit. However, there has not been the same emphasis applying gentle ventilation strategies immediately after birth. A lung-protective strategy should start immediately after birth to establish a functional residual capacity, reduce volutrauma and atelectotrauma, facilitate gas exchange, and improve oxygenation during neonatal transition. This article discusses techniques and equipment recommended by international resuscitation guidelines during breathing assistance in the delivery room.

    Full Text Available Background. Do-not-resuscitate (DNR orders are often active in patients with multiple comorbidities and a short natural life expectancy, but limited information exists as to how often these patients undergo high-risk operations and of the perioperative outcomes in this population. Methods. Using comprehensive inpatient administrative data from the Public Discharge Data file (years 2005 through 2010 of the California Office of Statewide Health Planning and Development, which includes a dedicated variable recording DNR status, we identified cohorts of DNR patients who underwent major cardiac or thoracic operations and compared themto age- and procedure-matched comparison cohorts. The primary study outcome was in-hospital mortality. Results. DNR status was not uncommon in cardiac (n = 2,678, 1.1% of all admissions for cardiac surgery, age 71.6 ± 15.9 years and thoracic (n = 3,129, 3.7% of all admissions for thoracic surgery, age 73.8 ± 13.6 years surgical patient populations. Relative to controls, patients who were DNR experienced significantly greater inhospital mortality after cardiac (37.5% vs. 11.2%, p < 0.0001 and thoracic (25.4% vs. 6.4% operations. DNR status remained an independent predictor of in-hospital mortality onmultivariate analysis after adjustment for baseline and comorbid conditions in both the cardiac (OR 4.78, 95% confidence interval 4.21–5.41, p < 0.0001 and thoracic (OR 6.11, 95% confidence interval 5.37–6.94, p < 0.0001 cohorts. Conclusions. DNR status is associated with worse outcomes of cardiothoracic surgery even when controlling for age, race, insurance status, and serious comorbid disease. DNR status appears to be a marker of substantial perioperative risk, and may warrant substantial consideration when framing discussions of surgical risk and benefit, resource utilization, and biomedical ethics surrounding end-of-life care.

    Introduction Shockable rhythms are rare in pediatric cardiac arrest and the results of defibrillation are uncertain. The objective of this study was to analyze the results of cardiopulmonary resuscitation that included defibrillation in children. Methods Forty-four out of 241 children (18.2%) who were resuscitated from inhospital or out-of-hospital cardiac arrest had been treated with manual defibrillation. Data were recorded according to the Utstein style. Outcome variables were a sustained return of spontaneous circulation (ROSC) and one-year survival. Characteristics of patients and of resuscitation were evaluated. Results Cardiac disease was the major cause of arrest in this group. Ventricular fibrillation (VF) or pulseless ventricular tachycardia (PVT) was the first documented electrocardiogram rhythm in 19 patients (43.2%). A shockable rhythm developed during resuscitation in 25 patients (56.8%). The first shock (dose, 2 J/kg) terminated VF or PVT in eight patients (18.1%). Seventeen children (38.6%) needed more than three shocks to solve VF or PVT. ROSC was achieved in 28 cases (63.6%) and it was sustained in 19 patients (43.2%). Only three patients (6.8%), however, survived at 1-year follow-up. Children with VF or PVT as the first documented rhythm had better ROSC, better initial survival and better final survival than children with subsequent VF or PVT. Children who survived were older than the finally dead patients. No significant differences in response rate were observed when first and second shocks were compared. The survival rate was higher in patients treated with a second shock dose of 2 J/kg than in those who received higher doses. Outcome was not related to the cause or the location of arrest. The survival rate was inversely related to the duration of cardiopulmonary resuscitation. Conclusion Defibrillation is necessary in 18% of children who suffer cardiac arrest. Termination of VF or PVT after the first defibrillation dose is achieved in a low

    Full Text Available Cardiac arrest during pregnancy is a dedicated chapter in the American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care; however, a robust maternal cardiac arrest knowledge translation strategy and emergency response plan is not usually the focus of institutional emergency preparedness programs. Although maternal cardiac arrest is rare, the emergency department is a high-risk area for receiving pregnant women in either prearrest or full cardiac arrest. It is imperative that institutions review and update emergency response plans for a maternal arrest. This review highlights the most recent science, guidelines, and recommended implementation strategies related to a maternal arrest. The aim of this paper is to increase the understanding of the important physiological differences of, and management strategies for, a maternal cardiac arrest, as well as provide institutions with the most up-to-date literature on which they can build emergency preparedness programs for a maternal arrest.

    The model for emergency department (ED) end-of-life communications after acute devastating events addresses decision-making capacity, surrogates, and advance directives, including legal definitions and application of these steps. Part II concerns communications moving from resuscitative to palliative and end-of-life treatments. After completing the steps involved in determining decision-making, emergency physicians (EPs) should consider starting palliative measures versus continuing resuscitative treatment. As communications related to these end-of-life decisions increasingly fall within the scope of emergency medicine (EM) practice, we need to become educated about and comfortable with them.

    Bone has one of the highest acoustic densities (AD) in the human body. Traditionally, bone has been considered to be a hindrance to the use of ultrasound (US), as US waves are reflected by the dense matrix and obscure underlying structures. The intense wave reflection, however, can clearly illustrate the cortical bony anatomy of long bones, making cortical disruption obvious. Ultrasound can be used at the bedside concurrently with the overall trauma resuscitation, and may potentially limit the patient's and treating team's exposure to ionizing radiation, corroborate clinical findings, and augment procedural success. The extended focused assessment with sonography for trauma (EFAST) is an essential tool in the resuscitation of severe torso trauma, frequently demonstrating intra- pericardial and intra-peritoneal fluid, inferring hemo/pneumothoraces, and demonstrating cardiac function. Although it is typically considered as a diagnosis of exclusion, multiple long-bone fractures may be a source of shock and can be quickly confirmed at the bedside with EFAST. Further, the early detection of long-bone fractures can also aid in the early stabilization of severely injured patients. Sonographic evaluation for long-bone fractures may be particularly useful in austere environments where other imaging modalities are limited, such as in the battlefield, developing world, and space. While prospective study has been limited, selected series have demonstrated high accuracy among both physician and para-medical clinicians in detecting long-bone fractures. Pitfalls in this technique include reduced accuracy with the small bones of the hands and feet, as well as great reliance on user experience. PMID:26815050

    In the latter half of the last century, cardiorespiratory arrest was not uncommon due to the anesthetic used (chloroform). Animal studies showed that the heart could be paced. One physician (Green) resuscitated 5 of 7 cardiac arrest patients with single stimuli applied to body surface electrodes. Another (McWilliam) issued a proposal for adoption of closed-chest pacing and provided information on the procedure. The following historical footnote describes these pioneering events in the history of cardiac pacing. PMID:7937239

    The management of trauma-related coagulopathy and haemorrhage is changing from a reactive strategy to a proactive early intervention with blood products and haemostatic agents. Although major haemorrhage and massive transfusion are associated with higher mortality, the pattern of this association with modern trauma care is poorly described. In addition, early predictors of massive transfusion, which might trigger a proactive haemostatic resuscitation strategy, are not currently available. We review recent literature relating to predictors of massive transfusions and the relationship between transfusion and mortality. PMID:21371347

    Objective: To compare the quality and correct the deficiencies of cardiopulmonary resuscitation (CPR) procedures performed in patients who developed cardiopulmonary cardiopulmonary arrest before or after Emergency Department admission. Methods: This study was conducted on patients who were applied CPR atŞŞişli Etfal Training and Research and Research Hospital, Emergency Department between 01 January 2012 and 31 December 2012. Chi-square and Mann-Whitney U test were used to compare the patients' data. The study data were analyzed in SPSS 18.0 software package. A P value less than 0.05 was considered statistically significant. Results: A total of 155 patients who were applied CPR were included in the analysis. Among the study patients, seventy eight (50.3%) were brought to Emergency Department after developing cardiopulmonary arrest while 77 (49.7%) developed cardiopulmonary arrest at Emergency Department. The mean age of the study population was (66 ± 16) years and 64%of the patients were male. The initial rhythms of the CPR-applied patients were different (P 0.05). The CPR response time was longer in ED (P Conclusions: The scientific data obtained in this study suggest that an early response and therapy improves outcomes in CPR procedure.

    Return of spontaneous circulation (ROSC) during chest compression is generally detected by arterial pulse palpation and end-tidal CO2 monitoring; however, it is necessary to stop chest compression during pulse palpation, and to perform endotracheal intubation for monitoring end-tidal CO2. In the present study, we evaluated whether near-infrared spectroscopy (NIRS) allows the detection of ROSC during chest compression without interruption. We monitored cerebral blood oxygenation in 19 patients with cardiac arrest using NIRS (NIRO-200NX, Hamamatsu Photonics, Japan). On arrival at the emergency room, the attending physicians immediately assessed whether a patient was eligible for this study after conventional advanced life support (ALS) and employed NIRS to measure cerebral blood oxygenation (CBO) in the bilateral frontal lobe in patients. We found cerebral blood flow waveforms in synchrony with chest compressions in all patients. In addition, we observed abrupt increases of oxy-hemoglobin concentration and tissue oxygen index (TOI), which were associated with ROSC detected by pulse palpation. The present findings indicate that NIRS can be used to assess the quality of chest compression in patients with cardiac arrest as demonstrated by the detection of synchronous waveforms during cardiopulmonary resuscitation (CPR). NIRS appears to be applicable for detection of ROSC without interruption of chest compression and without endotracheal intubation. PMID:26782207

    The effect of bretylium tosylate (BT) was determined in 27 consecutive cases of resistant ventricular fibrillation (VF) encountered by a hospital cardiac arrest team. The VF was sustained and completely resistant to multiple injections of lidocaine, sequential DC shocks at 400 watt-sec and one or a combination of intravenous propranolol, diphenylhydantoin or procainamide. Following 30 min of sustained cardiac massage, BT (5 mg/kg i.v.) was administered. In 20 patients, VF was terminated within 9-12 min after DC shock. Eight of these patients failed to recover while 12 (44%) of all patients resuscitated survived to be discharged from hospital. Eleven out of 20 (55%) of all patients who had a cardiac arrest outside the CCU were survivors; only one out of seven in the CCU were successfully resuscitated. While receiving maintanance BT post-resuscitation (5 mg/kg i.m. q 8-12 hrs x 48 hrs), half the patients developed hypotension and three required vasopressors and/or fluid replacement. The data indicate that BT is a useful agent in patients with sustained VF refractory to repeated lidocaine injections, some other antiarrhythmic agents, and multiple DC shocks. PMID:837490

    Objective The object of this study was to review the role of cardiac troponin as a prognostic factor in acute coronary syndrome patients of varying circumstances.Data sources The data used in this review were obtained mainly from the studies of cardiac troponin reported in pubmed from 1981 to 2006.Study selection Relevant articles on studies of cardiac troponin were selected.Results Elevated cardiac troponin in patients with ST elevation and non ST elevation myocardial infarction was associated with adverse outcomes, including a higher incidence of congestive heart failure, shock, and death. Patients with elevated cardiac troponin value seemed to benefit more from invasive strategies including a percutaneous coronary intervention and bypass surgery, but elevated cardiac troponin was also correlated with adverse outcomes, including a higher degree of failure, shock, and mortality in patients undergoing percutaneous coronary intervention; a higher degree of perioperative myocardial infarction, low cardiac output syndrome, cardiopulmonary resuscitation, and new-onset ventricular arrhythmia in patients undergoing bypass surgery were also observed. Elevated troponin after a percutaneous coronary intervention seemed to be associated with short-term adverse outcomes rather than long-term adverse outcomes, unless the elevation of the troponin post percutaneous coronary intervention was quite high (about 5 times above normal). On the contrary, elevated cardiac troponin after bypass surgery was more confusing to analyze since it happened in almost all patients. Furthermore, differences in cutoff values and time measurements in some studies add more confusion; thus, further research is warranted.Conclusions The prognostic value of cardiac troponin is demonstrated in almost all acute coronary syndrome patients. In addition to its high sensitivity and specificity, the prognostic value of cardiac troponin is another reason to make it the "golden cardiac marker' of this time.

    Purpose: It aimed to find if written test results improved for advanced cardiac life support (ACLS) taught in flipped classroom/team-based Learning (FC/TBL) vs. lecture-based (LB) control in University of California-Irvine School of Medicine, USA. Methods: Medical students took 2010 ACLS with FC/TBL (2015), compared to 3 classes in LB (2012-14) format. There were 27.5 hours of instruction for FC/TBL model (TBL 10.5, podcasts 9, small-group simulation 8 hours), and 20 (12 lecture, simulation 8 hours) in LB. TBL covered 13 cardiac cases; LB had none. Seven simulation cases and didactic content were the same by lecture (2012-14) or podcast (2015) as was testing: 50 multiple-choice questions (MCQ), 20 rhythm matchings, and 7 fill-in clinical cases. Results: 354 students took the course (259 [73.1%] in LB in 2012-14, and 95 [26.9%] in FC/TBL in 2015). Two of 3 tests (MCQ and fill-in) improved for FC/TBL. Overall, median scores increased from 93.5% (IQR 90.6, 95.4) to 95.1% (92.8, 96.7, P=0.0001). For the fill-in test: 94.1% for LB (89.6, 97.2) to 96.6% for FC/TBL (92.4, 99.20 P=0.0001). For MC: 88% for LB (84, 92) to 90% for FC/TBL (86, 94, P=0.0002). For the rhythm test: median 100% for both formats. More students failed 1 of 3 tests with LB vs. FC/TBL (24.7% vs. 14.7%), and 2 or 3 components (8.1% vs. 3.2%, P=0.006). Conversely, 82.1% passed all 3 with FC/TBL vs. 67.2% with LB (difference 14.9%, 95% CI 4.8-24.0%). Conclusion: A FC/TBL format for ACLS marginally improved written test results. PMID:26893399

  8. Cardiopulmonary resuscitation and contrast media reactions in a radiology department

    International Nuclear Information System (INIS)

    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).

    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.

    The lessons learned regarding the resuscitation of traumatic hemorrhagic shock are numerous and come from a better understanding of the epidemiology, pathophysiology, and experience in this population over 10-plus years of combat operations. We have now come to better understand that the greatest benefit in survival can come from improved treatment of hemorrhage in the prehospital phase of care. We have learned that there is an endogenous coagulopathy that occurs with severe traumatic injury secondary to oxygen debt and that classic resuscitation strategies for severe bleeding based on crystalloid or colloid solutions exacerbate coagulopathy and shock for those with life-threatening hemorrhage. We have relearned that a whole blood-based resuscitation strategy, or one that at least recapitulates the functionality of whole blood, may reduce death from hemorrhage and reduce the risks of excessive crystalloid administration which include acute lung injury, abdominal compartment syndrome, cerebral edema, and anasarca. Appreciation of the importance of shock and coagulopathy management underlies the emphasis on early hemostatic resuscitation. Most importantly, we have learned that there is still much more to understand regarding the epidemiology, pathophysiology, and the resuscitation strategies required to improve outcomes for casualties with hemorrhagic shock.

    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.

    2009-07-01

    Full Text Available Abstract Background Hands-Only cardiopulmonary resuscitation (CPR is recommended for use on adult victims of witnessed out-of-hospital (OOH sudden cardiac arrest or in instances where rescuers cannot perform ventilations while maintaining minimally interrupted quality compressions. Promotion of Hands-Only CPR should improve the incidence of bystander CPR and, subsequently, survival from OOH cardiac arrest; but, little is known about a rescuer's ability to deliver continuous chest compressions of adequate rate and depth for periods typical of emergency services response time. This study evaluated chest compression rate and depth as subjects performed Hands-Only CPR for 10 minutes. For comparison purposes, each also performed chest compressions with ventilations (30:2 CPR. It also evaluated fatigue and changes in body biomechanics associated with each type of CPR. Methods Twenty healthy female volunteers certified in basic life support performed Hands-Only CPR and 30:2 CPR on a manikin. A mixed model repeated measures cross-over design evaluated chest compression rate and depth, changes in fatigue (chest compression force, perceived exertion, and blood lactate level, and changes in electromyography and joint kinetics and kinematics. Results All subjects completed 10 minutes of 30:2 CPR; but, only 17 completed 10 minutes of Hands-Only CPR. Rate, average depth, percentage at least 38 millimeters deep, and force of compressions were significantly lower in Hands-Only CPR than in 30:2 CPR. Rates were maintained; but, compression depth and force declined significantly from beginning to end CPR with most decrement occurring in the first two minutes. Perceived effort and joint torque changes were significantly greater in Hands-Only CPR. Performance was not influenced by age. Conclusion Hands-Only CPR required greater effort and was harder to sustain than 30:2 CPR. It is not known whether the observed greater decrement in chest compression depth associated

    Background The use of extracorporeal life support (ECLS) in the setting of cardiopulmonary resuscitation (CPR) has shown improved outcomes compared with conventional CPR. The aim of this study was to determine factors predictive of survival in extracorporeal CPR (E-CPR). Methods Consecutive 85 adult patients (median age, 59 years; range, 18 to 85 years; 56 males) who underwent E-CPR from May 2005 to December 2012 were evaluated. Results Causes of arrest were cardiogenic in 62 patients (72.9%), septic in 18 patients (21.2%), and hypovolemic in 3 patients (3.5%), while the etiology was not specified in 2 patients (2.4%). The survival rate in patients with septic etiology was significantly poorer compared with those with another etiology (0% vs. 24.6%, p=0.008). Septic etiology (hazard ratio [HR], 2.84; 95% confidence interval [CI], 1.49 to 5.44; p=0.002) and the interval between arrest and ECLS initiation (HR, 1.05 by 10 minutes increment; 95% CI, 1.02 to 1.09; p=0.005) were independent risk factors for mortality. When the predictive value of the E-CPR timing for in-hospital mortality was assessed using the receiver operating characteristic curve method, the greatest accuracy was obtained at a cutoff of 60.5 minutes (area under the curve, 0.67; 95% CI, 0.54 to 0.80; p=0.032) with 47.8% sensitivity and 88.9% specificity. The survival rate was significantly different according to the cutoff of 60.5 minutes (p=0.001). Conclusion These results indicate that efforts should be made to minimize the time between arrest and ECLS application, optimally within 60 minutes. In addition, E-CPR in patients with septic etiology showed grave outcomes, suggesting it to be of questionable benefit in these patients. PMID:27525236

    Full Text Available Abstract Background Acute posthypoxic myoclonus (PHM can occur in patients admitted after cardiopulmonary resuscitation (CPR and is considered to have a poor prognosis. The origin can be cortical and/or subcortical and this might be an important determinant for treatment options and prognosis. The aim of the study was to investigate whether acute PHM originates from cortical or subcortical structures, using somatosensory evoked potential (SEP and electroencephalogram (EEG. Methods Patients with acute PHM (focal myoclonus or status myoclonus within 72 hours after CPR were retrospectively selected from a multicenter cohort study. All patients were treated with hypothermia. Criteria for cortical origin of the myoclonus were: giant SEP potentials; or epileptic activity, status epilepticus, or generalized periodic discharges on the EEG (no back-averaging was used. Good outcome was defined as good recovery or moderate disability after 6 months. Results Acute PHM was reported in 79/391 patients (20%. SEPs were available in 51/79 patients and in 27 of them (53% N20 potentials were present. Giant potentials were seen in 3 patients. EEGs were available in 36/79 patients with 23/36 (64% patients fulfilling criteria for a cortical origin. Nine patients (12% had a good outcome. A broad variety of drugs was used for treatment. Conclusions The results of this study show that acute PHM originates from subcortical, as well as cortical structures. Outcome of patients admitted after CPR who develop acute PHM in this cohort was better than previously reported in literature. The broad variety of drugs used for treatment shows the existing uncertainty about optimal treatment.

    2014-01-01

    Full Text Available Postcardiac arrest brain injury significantly contributes to mortality and morbidity in patients suffering from cardiac arrest (CA. Evidence that shows that mitochondrial dysfunction appears to be a key factor in tissue damage after ischemia/reperfusion is accumulating. However, limited data are available regarding the cerebral mitochondrial dysfunction during CA and cardiopulmonary resuscitation (CPR and its relationship to the alterations of high-energy phosphate. Here, we sought to identify alterations of mitochondrial morphology and oxidative phosphorylation function as well as high-energy phosphates during CA and CPR in a rat model of ventricular fibrillation (VF. We found that impairment of mitochondrial respiration and partial depletion of adenosine triphosphate (ATP and phosphocreatine (PCr developed in the cerebral cortex and hippocampus following a prolonged cardiac arrest. Optimal CPR might ameliorate the deranged phosphorus metabolism and preserve mitochondrial function. No obvious ultrastructural abnormalities of mitochondria have been found during CA. We conclude that CA causes cerebral mitochondrial dysfunction along with decay of high-energy phosphates, which would be mitigated with CPR. This study may broaden our understanding of the pathogenic processes underlying global cerebral ischemic injury and provide a potential therapeutic strategy that aimed at preserving cerebral mitochondrial function during CA.

    Full Text Available Williams syndrome is a complex syndrome characterized by developmental abnormalities, craniofacial dysmorphic features, and cardiac anomalies. Sudden death has been described as a very common complication associated with anesthesia, surgery, and procedures in this population. Anatomical abnormalities associated with the heart pre-dispose these individuals to sudden death. In addition to a sudden and rapid downhill course, lack of response to resuscitation is another significant feature seen in these patients. The authors report a five-year-old male with Williams syndrome, hypothyroidism, and attention deficit hyperactivity disorder. He suffered an anaphylactic reaction during CT imaging with contrast. Resuscitation was unsuccessful. Previous reports regarding the anesthetic management of patients with Williams are reviewed and the potential for sudden death or peri-procedure related cardiac arrest discussed in this report. The authors also review reasons for refractoriness to defined resuscitation guidelines in this patient population.

    Full Text Available Interposed abdominal compression cardiopulmonary resuscitation (IAC-CPR is an alternative technique to traditional cardiopulmonary resuscitation (CPR that can improve perfusion and lead to restoration of circulation in patients with chest wall deformity either acquired through vigorous CPR or co-morbidity such as chronic obstructive pulmonary disease. We report a case of out-of-hospital cardiac arrest where IAC-CPR allowed for restoration of spontaneous circulation and eventual full neurologic recovery when traditional CPR was failing to generate adequate pulses with chest compression alone.

    Full Text Available Spontaneous subarachnoid hemorrhage is the most common neurological disorder leading to pre-hospital cardiac arrest. ECG changes in SAH may mimic myocardial infarction or ischemia, and thus lead to delayed treatment of the primary problem. Early identification of SAH-induced cardiac arrest with the use of computed tomography scan of the brain obtained immediately after resuscitation will aid emergency physicians make further decisions. The overall prognosis of patients who are resuscitated is extremely poor. But, prompt neurosurgical referral and multidisciplinary intensive care management can improve the survival rate and the functional outcome. Thus, physicians should consider SAH as a differential diagnosis in patients presenting with pre-hospital cardiac arrest.

    A 75-year-old female presented for left total hip reimplantation and suffered pulseless electrical activity arrest upon lateral positioning and administering vancomycin. Resuscitation was achieved according to Advanced Cardiac Life Support protocol. Post-event echocardiography showed hypertrophic cardiomyopathy with asymmetrical septal thickening, an under-filled left ventricle, dynamic left ventricular outflow obstruction, and severe mitral regurgitation related to systolic anterior motion of the mitral valve. Laboratory analysis showed a tryptase level of 209 ng/mL. After multispecialty evaluation, it was concluded that the patient's arrest was due to vancomycin anaphylaxis in the setting of previously undiagnosed hypertrophic cardiomyopathy leading to acute left ventricular outflow tract obstruction. After medical optimization of the patient's cardiomyopathy and an evaluation of potential intraoperative allergic triggers, the patient underwent a successful hip reimplantation without incident. This case presents a novel combination of events leading to intraoperative cardiac arrest. Rapid identification and an understanding of the cause(s) of cardiac arrest in this setting are critical for effective perioperative care. PMID:27185714

    Coronary vasospasm is a rare diagnosis resulting in sudden arrhythmic cardiac arrest. We report a case of a healthy,non-smoking elderly woman resuscitated from arrhythmic cardiac arrest. She had persistent spontaneous coronaxy vasospasm, leading to right ventricular myocardial injury and failure, and shock. She responded quickly to intravenous normal saline bolus infusion, but had irreversible neurological sequelae. Additionally, she had atrial fibrillation preceding ischemic ventricular fibrillation, a rare finding in coronary vasospasm-related cardiac arrest. We suggest immediate coronary angiography of patients in sudden arrhythmic cardiac arrest with acute right ventricular failure for a prompt,accurate diagnosis and appropriate management of the coronary vasospasm.

  3. DNR policies in North America: A procedural morass - resuscitation practices revisited

    2006-01-01

    Full Text Available More than twenty-five years have elapsed since the first Do Not Resuscitate (DNR policies were proposed. A historical review of the application of DNR policies is provided with its rationale and perceived effects. A viewpoint is presented, that acceptance of implied consent for cardiopulmonary resuscitation (CPR in hospitalized patients was responsible for drawing up of DNR policies. Unfortunately, the principle of informed consent as related to CPR and DNR policies, has had unintended consequences. Practical results do not indicate that medical practices have become more humane. Abuses of the process go beyond matters of style and experience, in communicating with surrogate decision-makers. Instead of generating compassion and respect for the patient, policies may contribute to cynicism and lack of caring amongst physicians. Overly optimistic dependence on advance directives to reform medical practices, appears unjustified. The concept of futility to limit demands for non-beneficial care is examined. It is unlikely that physicians can routinely invoke futility, as an argument to limit treatments. A re-examination of DNR policies as a defense against technologic imperative is warranted.

    Full Text Available A satisfactory neurologic outcome is the key factor for survival in patients with sudden cardiac death (SCD, however this is highly dependent on the haemodynamic status. Short term cardiopulmonary resuscitation and regained consciousness on the return of spontaneous circulation (ROSC is indicative of a better prognosis. The evaluation and treatment of SCD triggering factors and of underlying acute and chronic diseases will facilitate prevention and lower the risk of cardiac arrest. Long term CPR and a prolonged unconscious status after ROSC, in the Intensive Care Units or Coronary Care Units, indicates the need for specific treatment and supportive therapy including efforts to prevent hyperthermia. The prognosis of these patients is unpredictable within the first seventy two hours, due to unknown responses to therapeutic management and the lack of specific prognostic factors. Patients in these circumstances require the highest level of intensive care and aetiology driven treatment without any delay, independently of their coma state. Current guidelines sugest the use of multiple procedures in arriving at a diagnosis and prognosis of these critical cases.

    Full Text Available Batteries used in Implantable cardiac pacemakers-present unique challenges to their developers and manufacturers in terms of high levels of safety and reliability. In addition, the batteries must have longevity to avoid frequent replacements. Technological advances in leads/electrodes have reduced energy requirements by two orders of magnitude. Micro-electronics advances sharply reduce internal current drain concurrently decreasing size and increasing functionality, reliability, and longevity. It is reported that about 600,000 pacemakers are implanted each year worldwide and the total number of people with various types of implanted pacemaker has already crossed 3 million. A cardiac pacemaker uses half of its battery power for cardiac stimulation and the other half for housekeeping tasks such as monitoring and data logging. The first implanted cardiac pacemaker used nickel-cadmium rechargeable battery, later on zinc-mercury battery was developed and used which lasted for over 2 years. Lithium iodine battery invented and used by Wilson Greatbatch and his team in 1972 made the real impact to implantable cardiac pacemakers. This battery lasts for about 10 years and even today is the power source for many manufacturers of cardiac pacemakers. This paper briefly reviews various developments of battery technologies since the inception of cardiac pacemaker and presents the alternative to lithium iodine battery for the near future.

    2015-01-01

    Cardiac fibrosis represents an adoptive response in the heart exposed to various stress cues. While resolution of the fibrogenic response heralds normalization of heart function, persistent fibrogenesis is usually associated with progressive loss of heart function and eventually heart failure. Cardiac fibrosis is regulated by a myriad of factors that converge on the transcription of genes encoding extracellular matrix proteins, a process the epigenetic machinery plays a pivotal role. In this minireview, we summarize recent advances regarding the epigenetic regulation of cardiac fibrosis focusing on the role of histone and DNA modifications and non-coding RNAs.

  14. Vasopressin Infusion with Small-Volume Fluid Resuscitation during Hemorrhagic Shock Promotes Hemodynamic Stability and Survival in Swine.

    Directory of Open Access Journals (Sweden)

    Raúl J Gazmuri

    Full Text Available Current management of hemorrhagic shock (HS in the battlefield and civilian settings favors small-volume fluid resuscitation before controlling the source of bleeding. We investigated in a swine model of HS the effects of vasopressin infusion along with small-volume fluid resuscitation; with erythropoietin (EPO and HS severity as additional factors.HS was induced in 24 male domestic pigs (36 to 41 kg by blood withdrawal (BW through a right atrial cannula modeling spontaneous bleeding by a mono-exponential decay function. The initial 12 pigs received no fluids; the last 12 pigs received normal saline (NS half the BW volume. Pigs were randomized 2:1 to receive intraosseously vasopressin (0.04 U/kg·min-1 or vehicle control from minute 7 to minute 210. Pigs assigned to vasopressin were further randomized 1:1 to receive EPO (1,200 U/kg or vehicle control and 1:1 to have 65% or 75% BW of their blood volume. Shed blood was reinfused at 210 minutes and the pigs recovered from anesthesia.Survival at 72 hours was influenced by vasopressin and NS but not by EPO or % BW. Vasopressin with NS promoted the highest survival (8/8 followed by vasopressin without NS (3/8, NS without vasopressin (1/4, and neither treatment (0/4 with overall statistical significance (log-rank test, p = 0.009 and each subset different from vasopressin with NS by Holm-Sidak test. Vasopressin increased systemic vascular resistance whereas NS increased cardiac output.Vasopressin infusion with small-volume fluid resuscitation during severe HS was highly effective enabling critical hemodynamic stabilization and improved 72 hour survival.

  15. Modified emergency department thoracotomy for postablation cardiac tamponade.

    2012-04-01

    Cardiac dysrhythmias are a common problem in the United States. Radiofrequency ablation is being used more frequently as a treatment for these diagnoses. Although rare, serious complications such as cardiac tamponade have been reported as a result of ablation procedures. Traditionally, emergency department (ED) thoracotomy has been reserved for cases of traumatic arrest only. We report a case of a successful modified ED thoracotomy in a patient with postablation cardiac tamponade and subsequent obstructive shock who failed intravenous fluid resuscitation, pressor administration, and multiple attempts at pericardiocentesis. In this case, a modified approach was used to incise the pericardium. Although this was associated with large blood loss, we believed that using the traditional method of completely removing the pericardium would have resulted in uncontrolled hemorrhage. Instead, our method led to successful resuscitation of the patient until definitive care was available. A smaller pericardial incision than is traditionally used during ED thoracotomy deserves further consideration and research to determine whether and when it may be most useful as a temporizing treatment of cardiac tamponade when other methods have failed.

    Although anti-IL-6-mAb down-regulates cardiac IL-6 and attenuates IL-6-mediated cardiac dysfunction following trauma-hemorrhage, it is not known whether blockade of IL-6 receptor will down-regulate cardiac IL-6 and improve cardiac function under those conditions. Six groups of male adult rats (275-325 g) were used: sham/trauma-hemorrhage+vehicle, sham/trauma-hemorrhage+IgG, sham/trauma-hemorrhage+anti-rat sIL-6R. Rats underwent trauma-hemorrhage (removal of 60% of the circulating blood volume and fluid resuscitation after 90 min). Vehicle (V), normal goat IgG or anti-rat sIL-6R (16.7 microg/kg BW) was administered intra-peritoneally in the middle of resuscitation. Two hours later, cardiac function was measured by ICG dilution technique; blood samples collected, cardiomyocytes isolated, and cardiomyocyte nuclei were then extracted. Cardiac IL-6, IL-6R, gp130, IkappaB-alpha/P-IkappaB-alpha, NF-kappaB, and ICAM-1 expressions were measured by immunoblotting. Plasma IL-6 and cardiomyocyte NF-kappaB DNA-binding activity were determined by ELISA. In additional animals, heart harvested and cardiac MPO activity and CINC-1 and -3 were also measured. In another group of rats, cardiac function was measure by microspheres at 24 h following trauma-hemorrhage. Cardiac function was depressed and cardiac IL-6, P-IkappaB-alpha, NF-kappaB and its DNA-binding activity, ICAM-1, MPO activity, and CINC-1 and -3 were markedly increased after trauma-hemorrhage. Moreover, cardiac dysfunction was evident even 24 h after trauma-hemorrhage. Administration of sIL-6R following trauma-hemorrhage: (1) improved cardiac output at 2 h and 24 h (p<0.05); (2) down-regulated both cardiac IL-6 and IL-6R (p<0.05); and (3) attenuated cardiac P-IkappaB-alpha, NF-kappaB, NF-kappaB DNA-binding activity, ICAM-1, CINC-1, -3, and MPO activity (p<0.05). IgG did not significantly influence the above parameters. Thus, IL-6-mediated up-regulation of cardiac NF-kappaB, ICAM-1, CINC-1, -3, and MPO activity likely

    Full Text Available Abstract Background Traumatic injury is a leading cause of morbidity and mortality in developed countries worldwide. Recent studies suggest that many deaths are preventable if injuries are recognized and treated in an expeditious manner – the so called 'golden hour' of trauma. Ultrasound revolutionized the care of the trauma patient with the introduction of the FAST (Focused Assessment with Sonography for Trauma examination; a rapid assessment of the hemodynamically unstable patient to identify the presence of peritoneal and/or pericardial fluid. Since that time the use of ultrasound has expanded to include a rapid assessment of almost every facet of the trauma patient. As a result, ultrasound is not only viewed as a diagnostic test, but actually as an extension of the physical exam. Methods A review of the medical literature was performed and articles pertaining to ultrasound-assisted assessment of the trauma patient were obtained. The literature selected was based on the preference and clinical expertise of authors. Discussion In this review we explore the benefits and pitfalls of applying resuscitative ultrasound to every aspect of the initial assessment of the critically injured trauma patient.

    Parenteral thiamine has a very high safety profile. The most common adverse effect is local irritation; however, anaphylactic or anaphylactoid reactions may occur, mostly related to intravenous administration. We describe a 44-year-old man, a chronic alcoholic, who was admitted with alcohol intoxication and developed cardiac arrest due to anaphylactic shock following intravenous thiamine infusion. The patient was successfully resuscitated after 15 min and repeated epinephrine administrations. He was discharged in good health after 14 days. This case report emphasises both the importance of recognising the symptoms of anaphylaxis and the fact that facilities for treating anaphylaxis and cardiopulmonary resuscitation should be available when thiamine or for that matter, any drug is given in-hospital.

    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.

    Understanding the mutual relationship between the liver and the heart is important for both hepatologists and cardiologists. Hepato-cardiac diseases can be classified into heart diseases affecting the liver, liver diseases affecting the heart, and conditions affecting the heart and the liver at the same time. Differential diagnoses of liver injury are extremely important in a cardiologist’s clinical practice calling for collaboration between cardiologists and hepatologists due to the many other diseases that can affect the liver and mimic haemodynamic injury. Acute and chronic heart failure may lead to acute ischemic hepatitis or chronic congestive hepatopathy. Treatment in these cases should be directed to the primary heart disease. In patients with advanced liver disease, cirrhotic cardiomyopathy may develop including hemodynamic changes, diastolic and systolic dysfunctions, reduced cardiac performance and electrophysiological abnormalities. Cardiac evaluation is important for patients with liver diseases especially before and after liver transplantation. Liver transplantation may lead to the improvement of all cardiac changes and the reversal of cirrhotic cardiomyopathy. There are systemic diseases that may affect both the liver and the heart concomitantly including congenital, metabolic and inflammatory diseases as well as alcoholism. This review highlights these hepatocardiac diseases

    Background Few studies have reported the effect of different volume responsiveness evaluation methods on volume therapy results and prognosis.This study was carried out to investigate the effect of two volume responsiveness evaluation methods,stroke volume variation (SW) and stroke volume changes before and after passive leg raising (PLR-ASV),on fluid resuscitation and prognosis in septic shock patients.Methods Septic shock patients admitted to the Department of Critical Care Medicine of Zhejiang Hospital,China,from March 2011 to March 2013,who were under controlled ventilation and without arrhythmia,were studied.Patients were randomly assigned to the SVV group or the PLR-ASV group.The SVV group used the Pulse Indication Continuous Cardiac Output monitoring of SW,and responsiveness was defined as SW->12%.The PLR-ASV group used ASV before and after PLR as the indicator,and responsiveness was defined as ASV >15%.Six hours after fluid resuscitation,changes in tissue perfusion indicators (lactate,lactate clearance rate,central venous oxygen saturation (SCVO2),base excess (BE)),organ function indicators (white blood cell count,neutrophil percentage,platelet count,total protein,albumin,alanine aminotransferase,total and direct bilirubin,blood urea nitrogen,serum creatinine,serum creatine kinase,oxygenation index),fluid balance (6-and 24-hour fluid input) and the use of cardiotonic drugs (dobutamine),prognostic indicators (the time and rate of achieving early goal-directed therapy (EGDT) standards,duration of mechanical ventilation and intensive care unit stay,and 28-day mortality) were observed.Results Six hours after fluid resuscitation,there were no significant differences in temperature,heart rate,blood pressure,SpO2,organ function indicators,or tissue perfusion indicators between the two groups (P >0.06).The 6-and 24-hour fluid input was slightly less in the SW group than in the PLR-ASV group,but the difference was not statistically significant (P >0

  3. Comparison of superior vena caval and inferior vena caval access using a radioisotope technique during normal perfusion and cardiopulmonary resuscitation

    International Nuclear Information System (INIS)

    Recent studies of thoracic pressure changes during external cardiopulmonary resuscitation (CPR) suggest that there may be a significant difference in the rate of delivery of intravenous drugs when they are administered through the extrathoracic inferior vena cava (IVC) rather than the intrathoracic superior vena cava (SVC). Comparison of delivery of a radionuclide given using superior and inferior vena caval access sites was made during normal blood flow and during CPR. Mean times from injection to peak emission count in each ventricle were determined. There were no significant differences between mean peak times for SVC or IVC routes during normal flow or CPR. When peak times were corrected for variations in cardiac output, there were no significant differences between IVC and SVC peak times during normal flow. During CPR, however, mean left ventricular peak time, when corrected for cardiac output, was significantly shorter (P less than .05) when the SVC route was used. The mean time for the counts to reach half the ventricular peak was statistically shorter (P less than .05) in both ventricles with the SVC route during the low flow of CPR. This suggests that during CPR, increased drug dispersion may occur when drugs are infused by the IVC route and thus may modify the anticipated effect of the drug bolus. These results suggest that during CPR, both the cardiac output and the choice of venous access are important variables for drug delivery

    Full Text Available Operating room fires are rare events, but when occur they result in serious and sometimes fatal consequences. Anaesthesia ventilator fire leading to cardiac arrest is a rare incident and has not been reported. We report a near catastrophic ventilator fire leading to cardiac arrest in a patient undergoing subtotal thyroidectomy. In the present case sparks due to friction or electrical short circuit within the ventilator might have acted as source of ignition leading to fire and explosion in the oxygen rich environment. The patient was successfully resuscitated and revived with uneventful recovery and no adverse sequelae. The cardiac arrest was possibly due to severe hypoxia resulting from inhalation of smoke containing high concentrations of carbon monoxide and other noxious gases.

    Full Text Available Functional systemic approach to the resuscitation and intensive care may be considered as a direct correlation between analysis and synthesis, induction and deduction, and, in general, between the formal and dialectical categories. The realization of this system should be started with the interaction and formation of the final beneficial result. Therefore the experience assessment on the basis of functional systematic approach will enable us to formulate more precisely the subject and methods of resuscitation from the philosophical point of view taking into consideration the interaction of the human life integrity with death phenomenon as fixed in ontogenesis and will allow to methodically justify the distinguishing of functional systems and standard processes both in sanogenesis and thanatogenesis.

    Neonatal resuscitation is one of the most frequently performed procedures, and it is often successful if the ventilation applied is adequate. Over the last decade, interest in seeking objectivity in evaluating the infant's condition at birth or the adequacy and effect of the interventions applied has markedly increased.

    the early recognition and delivery of cardiopulmonary resuscitation maneuvers focused on high-quality thoracic compressions and rapid defibrillation by means of the implementation of public access-to-defibrillation programs. These aspects are of the utmost importance and may make the difference on the patient's outcomes, such as on hospital survival with no permanent neurological damage. Early initiation of the Advanced Cardiology Life Support also plays an essential role by keeping the quality of thoracic compressions; adequate airway management; specific treatment for the different arrest rhythms; defibrillation; and assessment and treatment of the possible causes during all the assistance. More recently, emphasis has been given to post-resuscitation care, with the purpose of reducing mortality by means of early recognition and treatment of the post-cardiac arrest syndrome. Therapeutic hypothermia has provided significant improvement of neurological damage and should be performed in comatose individuals post-cardiac arrest. For physicians working in the emergency department or intensive care unit, it is extremely important to improve the treatment given to these patients by means of specific training, thus giving them the chance of higher success and of better survival rates.

    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.

    Patients with injuries severe enough to require cardiopulmonary resuscitation (CPR) have a dismal prognosis. Time to surgical intervention is a major determinant of outcome in moribund trauma patients who have a potential for survival. With the exception of endotracheal intubation during evacuation to surgical intervention, no other usual prehospital procedures have been validated to affect outcome in such cases of extremis. This is a report of a case in which resuscitative surgical techniques were extended successfully to the prehospital environment. The patient was a 30-year-old man in extremis after a stab wound to the left chest. Estimating a transport time of 15 minutes, a physician riding with the emergency medical service (EMS) crews elected to perform a resuscitative thoracotomy. Following digital aortic compression, the patient regained both blood pressure and consciousness by the time of arrival at the trauma center. A left lower lobectomy was then performed in the operating room. The patient recovered fully and was discharged home in 21 days, neurologically intact. Four years later, the patient was alive, healthy, and working. This report demonstrates the feasibility of prehospital thoracotomy and raises provocative issues regarding future intense surgical involvement in prehospital care. PMID:8295241

    Full Text Available Road traffic accident victims, as well as persons experiencing cardiac and other medical emergencies, might lose their lives due to the non-availability of trained personnel to provide effective cardio-pulmonary resuscitation (CPR with functional equipment and adequate resources.The objectives of the study were to identify unit managers’ perceptions about challenges encountered when performing CPR interventions in the two referral public hospitals in Botswana. These results could be used to recommend more effective CPR strategies for Botswana’s hospitals. Interviews, comprising two quantitative sections with closed ended questions and one qualitative section with semi-structured questions, were conducted with 22 unit managers. The quantitative data indicated that all unit managers had at least eight years’ nursing experience, and could identify CPR shortcomings in their hospitals. Only one interviewee had never performed CPR. The qualitative data analysis revealed that the hospital units sometimes had too few staff members and did not have fully equipped emergency trolleys and/or equipment. No CPR teams and no CPR policies and guidelines existed. Nurses and doctors reportedly lacked CPR knowledge and skills. No debriefing services were provided after CPR encounters. The participating hospitals should address the following challenges that might affect CPR outcomes: shortages of staff, overpopulation of hospital units, shortcomings of the emergency trolleys and CPR equipment, absence of CPR policies and guidelines, absence of CPR teams, limited CPR competencies of doctors and nurses and the lack of debriefing sessions after CPR attempts.

    LUCAS is a new gas-driven CPR device providing automatic chest compression and active decompression. In an artificial thorax model, superior pressure and flow were obtained with LUCAS compared with manual CPR. In a randomized study on pigs with induced ventricular fibrillation significantly higher cardiac output, carotid artery blood flow, end-tidal CO(2), intrathoracic decompression-phase aortic- and coronary perfusion pressures were obtained with LUCAS-CPR (83% ROSC) compared to manual CPR (0% ROSC). In normothermic fibrillating pigs, the ROSC rate was 100% after 15 min and 38% after 60 min of LUCAS-CPR (no drug treatment). The ROSC rate increased to 75% if surface cooling to 34 degrees C was applied during the first 30 min of the 1-h resuscitation period. Experience with the first 20 patients has shown that LUCAS is light (6.5 kg), easy to handle, quick to apply (10-20 s), maintains a correct position, and works optimally during transport both on stretchers and in ambulances. In one hospital patient with a witnessed asystole where manual CPR failed, LUCAS-CPR achieved ROSC within 3 min. One year later the patient's mental capacity was fully intact. To conclude, LUCAS-CPR gives significantly better circulation during ventricular fibrillation than manual CPR. PMID:12458066

    Good quality cardiopulmonary resuscitation (CPR) is the mainstay of treatment for managing patients with out-of-hospital cardiac arrest (OHCA). Assessment of the quality of the CPR delivered is now possible through the electrocardiography (ECG) signal that can be collected by an automated external defibrillator (AED). This study evaluates a nonlinear approximation of the CPR given to the asystole patients. The raw ECG signal is filtered using ensemble empirical mode decomposition (EEMD), and the CPR-related intrinsic mode functions (IMF) are chosen to be evaluated. In addition, sample entropy (SE), complexity index (CI), and detrended fluctuation algorithm (DFA) are collated and statistical analysis is performed using ANOVA. The primary outcome measure assessed is the patient survival rate after two hours. CPR pattern of 951 asystole patients was analyzed for quality of CPR delivered. There was no significant difference observed in the CPR-related IMFs peak-to-peak interval analysis for patients who are younger or older than 60 years of age, similarly to the amplitude difference evaluation for SE and DFA. However, there is a difference noted for the CI (p CPR-IMFs amplitude differences. PMID:27529068

    Full Text Available Cardiopulmonary resuscitation (CPR is an effective intervention for prehospital cardiac arrest. Despite all available training opportunities for CPR, disparities exist in participation in CPR training, CPR knowledge, and receipt of bystander CPR for certain ethnic groups. We conducted five focus groups with Chinese immigrants who self-reported limited English proficiency (LEP. A bilingual facilitator conducted all the sessions. All discussions were taped, recorded, translated, and transcribed. Transcripts were analyzed by content analysis guided by the theory of diffusion. The majority of participants did not know of CPR and did not know where to get trained. Complexity of CPR procedure, advantages of calling 9-1-1, lack of confidence, and possible liability discourage LEP individuals to learn CPR. LEP individuals welcome simplified Hands-Only CPR and are willing to perform CPR with instruction from 9-1-1 operators. Expanding the current training to include Hands-Only CPR and dispatcher-assisted CPR may motivate Chinese LEP individuals to get trained for CPR.

  7. Cardiovascular gas on non-traumatic postmortem computed tomography (PMCT). The influence of cardiopulmonary resuscitation

    International Nuclear Information System (INIS)

    The purpose of this study was to investigate the causes of cardiovascular gas (CVG) detected on non-traumatic postmortem computed tomography (PMCT). PMCT was performed on 247 subjects within two hours of non-traumatic death, including 228 patients who had undergone cardiopulmonary resuscitation (CPR) and 19 patients who had not. We evaluated the incidence and distribution of CVG in four areas of the heart, namely, the upper course of the right atrium (UC-RA), the right atrium, the right ventricle, and the left heart (left atrium, left ventricle, and aorta). CVG was observed in 163 (71%) of the 228 patients who underwent CPR. In those 163 patients, we detected CVG in the UC-RA (103 patients), right atrium (81 patients), right ventricle (94 patients), and left heart (5 patients). Nineteen patients who received no CPR showed no CVG. CVG on non-traumatic PMCT is mainly caused by CPR, which is characterized by venous catheterization that permits possible air inflow and by pneumatization of dissolved gas in the blood as a result of cardiac massage.

    Following a chemical, biological, radiation, and nuclear incident, prompt cardiopulmonary resuscitation (CPR) procedure is essential for patients who suffer cardiac arrest. But CPR when wearing personal protection equipment (PPE) before decontamination becomes a challenge for healthcare workers (HCW). Although previous studies have assessed the impact of PPE on airway management, there is little research available regarding the quality of chest compression (CC) when wearing PPE.A present randomized cross-over simulation study was designed to evaluate the effect of PPE on CC performance using mannequins.The study was set in one university medical center in the China.Forty anesthesia residents participated in this randomized cross-over study.Each participant performed 2 min of CC on a manikin with and without PPE, respectively. Participants were randomized into 2 groups that either performed CC with PPE first, followed by a trial without PPE after a 180-min rest, or vice versa.CPR recording technology was used to objectively quantify the quality of CC. Additionally, participants' physiological parameters and subjective fatigue score values were recorded.With the use of PPE, a significant decrease of the percentage of effective compressions (41.3 ± 17.1% with PPE vs 67.5 ± 15.6% without PPE, P < 0.001) and the percentage of adequate compressions (67.7 ± 18.9% with PPE vs 80.7 ± 15.5% without PPE, P < 0.001) were observed. Furthermore, the increases in heart rate, mean arterial pressure, and subjective fatigue score values were more obvious with the use of PPE (all P < 0.01).We found significant deterioration of CC performance in HCW with the use of a level-C PPE, which may be a disadvantage for enhancing survival of cardiac arrest.

    International Nuclear Information System (INIS)

    Objective: To assess the level of awareness regarding basic and practical knowledge of cardiopulmonary resuscitation and its importance in the eyes of medical/dental students and doctors. Methods: The cross-sectional study was conducted in medical and dental colleges as well as hospitals of Rawalpindi and Islamabad, Pakistan, from June to September 2011. Non-probability convenience sampling was used and structured questionnaires on basic and practical knowledge of the procedure were distributed. The questionnaire had 26 items related to basic and advanced knowledge of the required skills. Doctors were divided into two groups based on their years of service and practice. Those with less than 5 years' experience were grouped as junior doctors, while rest as senior doctors. Descriptive statistics were employed to analyse the data using SPPS version 17 and Microsoft Excel. Percentages were worked out and the results were interpreted. Result: Of the 1000 questionnaires distributed, 646 (64.6%) were received duly filled and represented the study sample. Of the 646 participants, 34 (5.26%) were dentists, 424 (65.63%) were medical students, 92 (14.24%) were doctors and 96 (14.86%) were dental students. Basic knowledge of doctors was found to be better than that of dentists (n=96; 50% vs. n=8; 23%). Similarly, the advance knowledge of doctors was better than the dentists (n=53; 58% vs. n=11; 31%). The basic knowledge of junior doctors was found to be almost equal to the senior doctors (n=26; 44.75% vs. n=15; 45.5%). The advance knowledge of junior doctors was found to be better than the senior doctors (n=27; 45.37% vs. n=10; 29.48%). Among the students, 157 (37%) of the medical students had basic knowledge of CPR, while 36 (38%) dental students had basic knowledge of the topic. Medical students had more advanced knowledge (n=157; 37%) than dental students (n=34; 35%). Conclusion: The awareness of basic and advance knowledge of cardiopulmonary resuscitation skills in medical

    Full Text Available Mepivacaine is a potent local anaesthetic and used for infiltration and regional anaesthesia in adults and pediatric patients. Intoxications with mepivacaine affect mainly the CNS and the cardiovascular system. We present a case of accidental intravenous mepivacaine application and intoxication of an infant resulting in seizure, broad complex bradyarrhythmia, arterial hypotension and finally cardiac arrest. The patient could be rescued by prolonged resuscitations and a rapid initiation of ECMO and survived without neurological damage. The management strategies of this rare complication including promising other treatment options with lipid emulsions are discussed.

    Cardiac arrest (CA) is a major cause of morbidity and mortality worldwide. Despite the use of conventional cardiopulmonary resuscitation (CPR), rates of return of spontaneous circulation and survival with minimal neurologic impairment remain low. Utilization of venoarterial extracorporeal membrane oxygenation (ECMO) for CA in adults is steadily increasing. Propensity-matched cohort studies have reported outcomes associated with ECMO use to be superior to that of conventional CPR alone in in-hospital patients with CA. In this review, we discuss the mechanism, indications, complications, and evidence for ECMO in CA in adults. PMID:25922385

    Cardiac electromechanical dysfunction may compromise recovery of patients who are initially resuscitated from cardiac arrest, and effective treatments remain elusive. Pyruvate, a natural intermediary metabolite, energy substrate, and antioxidant, has been found to protect the heart from ischemia-reperfusion injury. This study tested the hypothesis that pyruvate-enriched resuscitation restores hemodynamic, metabolic, and electrolyte homeostasis following cardiac arrest. Forty-two Yorkshire swine underwent pacing-induced ventricular fibrillation and, after 6 min pre-intervention arrest, 4 min precordial compressions followed by transthoracic countershocks. After defibrillation and recovery of spontaneous circulation, the pigs were monitored for another 4 h. Sodium pyruvate or NaCl were infused i.v. (0.1 mmol·kg(-1)·min(-1)) throughout precordial compressions and the first 60 min recovery. In 8 of the 24 NaCl-infused swine, the first countershock converted ventricular fibrillation to pulseless electrical activity unresponsive to subsequent countershocks, but only 1 of 18 pyruvate-treated swine developed pulseless electrical activity (relative risk 0.17; 95% confidence interval 0.13-0.22). Pyruvate treatment also lowered the dosage of vasoconstrictor phenylephrine required to maintain systemic arterial pressure at 15-60 min recovery, hastened clearance of excess glucose, elevated arterial bicarbonate, and raised arterial pH; these statistically significant effects persisted up to 3 h after sodium pyruvate infusion, while infusion-induced hypernatremia subsided. These results demonstrate that pyruvate-enriched resuscitation achieves electrocardiographic and hemodynamic stability in swine during the initial recovery from cardiac arrest. Such metabolically based treatment may offer an effective strategy to support cardiac electromechanical recovery immediately after cardiac arrest. PMID:26088865

    patients in general hospitals from Salvador were prospectively assessed through bivariate and stratified analysis in associations between variables and survival curve for a nine-year evolution assessment. RESULTS: Age ranged from 14 to 93 years old, mean of 54.11 years old. Male gender patients prevailed and half of them had at least a base disease. Cardiovascular disease was the responsible etiology in 50% of cases. Cardiac arrest was observed in 77% of cases and only 69% of patients were immediately resuscitated. Initial cardiac rhythm was not diagnosed in 59% of patients. Asystole was the most frequent rhythm (42%, followed by ventricular arrhythmia (35%. Immediate survival was 24% and hospital discharge survival 5%. Cardiac arrest etiology, initial cardiac rhythm diagnosis, ventricular fibrillation or tachycardia as arrest mechanism, pre-resuscitation estimated time lower than or equal to 15 minutes and resuscitation time lower than or equal to 5 minutes were recognized as short-term prognostic factors. Non-administration of epinephrine, being resuscitated in private hospital and resuscitation time lower than or equal to 15 minutes were nine-year evolution survival prognostic factors. CONCLUSION: Data may help healthcare professionals decide when start or stop in-hospital resuscitation.

    Recent combat experience reignited interest in transfusing whole blood (WB) for patients with life-threatening bleeding. US Army data indicate that WB transfusion is associated with improved or comparable survival compared to resuscitation with blood components. These data complement randomized controlled trials that indicate that platelet (PLT)-containing blood products stored at 4°C have superior hemostatic function, based on reduced bleeding and improved functional measures of hemostasis, compared to PLT-containing blood products at 22°C. WB is rarely available in civilian hospitals and as a result is rarely transfused for patients with hemorrhagic shock. Recent developments suggest that impediments to WB availability can be overcome, specifically the misconceptions that WB must be ABO specific, that WB cannot be leukoreduced and maintain PLTs, and finally that cold storage causes loss of PLT function. Data indicate that the use of low anti-A and anti-B titer group O WB is safe as a universal donor, WB can be leukoreduced with PLT-sparing filters, and WB stored at 4°C retains PLT function during 15 days of storage. The understanding that these perceived barriers are not insurmountable will improve the availability of WB and facilitate its use. In addition, there are logistic and economic advantages of WB-based resuscitation compared to component therapy for hemorrhagic shock. The use of low-titer group O WB stored for up to 15 days at 4°C merits further study to compare its efficacy and safety with current resuscitation approaches for all patients with life-threatening bleeding.

    Postresuscitation debriefings allow team members to reflect on performance and discuss areas for improvement. Pre-/postsurveys of trauma team members (physicians, mid-level practitioners, technicians, pharmacists, and nurses) were administered to evaluate the acceptability of debriefings and self-perceptions after multidisciplinary trauma resuscitations. After a 3-month trial period, improvements were observed in perceptions of psychological and patient safety, role on team, team communication, and acceptability of the debriefing initiative. Regrouping for a debriefing requires organizational change, which may be more easily assimilated if team members recognize the potential for process improvement and feel confident about success.

    Even if Belgium (2002), The Netherlands (2002) and Luxemburg (2009) are the first three countries in the world to have legalized active euthanasia, there still is not a law on the do not resuscitate concept (NTBR or DNR). Nevertheless, numerous royal decrees and some consensus as well as advice given by the Belgian Medical Council, hold as jurisprudence. These rules remain amenable to change so as to suite the daily practice in intensive care units.

    The study is to present the results of works on creation of methods of automatic control procedures of cardiopulmonary resuscitation (CPR). A method of automatic control procedure of CPR by evaluating the acoustic data of the dynamics of blood flow in the bifurcation of carotid arteries and the dynamics of air flow in a trachea according to the current guidelines for CPR is presented. Evaluation of the patient is carried out by analyzing the respiratory noise and blood flow in the interspaces between the chest compressions and artificial pulmonary ventilation. The device operation algorithm of automatic control procedures of CPR and its block diagram has been developed.

  13. Potential wrist ligament injury in rescuers performing cardiopulmonary resuscitation

    Full Text Available Wrist pain in rescuers performing chest compressions as part of cardiopulmonary resuscitation has been reported anecdotally and recently in the literature. Studies have indicated that rescuers apply as much as 644 N of force to the victim′s chest with each compression, while standards require one hundred compressions per minute. Recent research suggests that forces transmitted through the rescuers′ wrists of less than 10% of those seen during the performance of chest compressions significantly strain the scapholunate ligament. Biomechanical research should be performed to further evaluate this possible correlation. Compensation for worker injury maybe involved.

    Full Text Available Brugada syndrome is a heritable arrhythmia syndrome that is characterized by an electrocardiographic pattern consisting of coved-type ST-segment elevation (2 mm followed by a negative T wave in the right precordial leads, V1 through V3 (often referred to as type 1 Brugada electrocardiographic pattern, here we describe 3 cases of Brugada who survived sudden cardiac death (SCD cardiac center experience with survived Brugada syndrome patients – case series. First Case: The Father 45 years old male, presented in 2005 after involvement in unprovoked motor vehicle accident, the patient was the driver who lost consciousness and rushed to the hospital. On arrival to our ER and putting the patient on the bed, the ER doctor observed a brief episode of VF on the monitor. The patient was taken to the catheterization Lab , his coronaries were normal. The diagnosis of Brugada was established and the patient received a defibrillator. At That Time all family members were screened and were negative. Second Case: The Son of the first patient 5 years later his 23 years old male rushed to our ER after he lost consciousness, he was passenger in the car of his friend. Third Case: The pilot A military pilot aged a male 35 years old was in very good health when he lost consciousness and brought to the hospital after resuscitation in 2005. He had full invasive cardiac evaluation, subsequently he received a defibrillator in the same admission period, till 2015 he is doing fine. Brugada syndrome is associated with high tendency for sudden cardiac death. In our three cases the first clinical presentation was survived sudden cardiac death (SCD and all three male patients survived. We did not encounter a female patient who survived sudden cardiac death.

    2011-03-01

    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. Scenario: Cardiac arrest during simulated inter-hospital transfer. Results 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 Conclusion Neither review nor team briefing improved the time to resuscitation key elements. Review led to an eight-fold increase in the delay to requesting help. The association between never requesting help and an increased hands-off ratio underpins the importance of prioritising available resources. Other medical

    Sudden cardiac death is the most common cause of unnatural death in football. To prevent and urgently manage sudden cardiac arrest on the football field-of-play, F-MARC (FIFA Medical and Research Centre) has been fully committed to a programme of research, education, standardisation and practical implementation. This strategy has detected football players at medical risk during mandatory precompetition medical assessments. Additionally, FIFA has (1) sponsored internationally accepted guidelines for the interpretation of an athlete's ECG, (2) developed field-of-play-specific protocols for the recognition, response, resuscitation and removal of a football player having sudden cardiac arrest and (3) introduced and distributed the FIFA medical emergency bag which has already resulted in the successful resuscitation of a football player who had a sudden cardiac arrest on the field-of-play. Recently FIFA, in association with the Institute of Sports and Preventive Medicine in Saarbrücken, Germany, established a worldwide Sudden Death Registry with a view to documenting fatal events on the football field-of-play. These activities by F-MARC are testimony to FIFA's continued commitment to minimising sudden cardiac arrest while playing football. PMID:25878076

    Full Text Available Abstract Background Cardiac arrest victims most often collapse at home, where only a modest proportion receives life-saving bystander cardiopulmonary resuscitation. As many as 40% of all sudden cardiac arrest victims have agonal or abnormal breathing in the first minutes following cardiac arrest. 9-1-1 call takers may wrongly interpret agonal breathing as a sign of life, and not initiate telephone cardiopulmonary resuscitation instructions. Improving 9-1-1 call takers' ability to recognize agonal breathing as a sign of cardiac arrest could result in improved bystander cardiopulmonary resuscitation and survival rates for out-of-hospital cardiac arrest victims. Methods/Design The overall goal of this study is to design and conduct a survey of 9-1-1 call takers in the province of Ontario to better understand the factors associated with the successful identification of cardiac arrest (including patients with agonal breathing over the phone, and subsequent administration of cardiopulmonary resuscitation instructions to callers. This study will be conducted in three phases using the Theory of Planned Behaviour. In Phase One, we will conduct semi-structured qualitative interviews with a purposeful selection of 9-1-1 call takers from Ontario, and identify common themes and belief categories. In Phase Two, we will use the qualitative interview results to design and pilot a quantitative survey. In Phase Three, a final version of the quantitative survey will be administered via an electronic medium to all registered call takers in the province of Ontario. We will perform qualitative thematic analysis (Phase One and regression modelling (Phases Two and Three, to determine direct and indirect relationship of behavioural constructs with intentions to provide cardiopulmonary resuscitation instructions. Discussion The results of this study will provide valuable insight into the factors associated with the successful recognition of agonal breathing and cardiac

    2016-01-01

    Long-term cardiac effects are an important component of survivorship after breast radiotherapy. The pathophysiology of cardiotoxicity, history of breast radiotherapy, current methods of cardiac avoidance, modern outcomes, context of historical outcomes, quantifying cardiac effects, and future directions are reviewed in this article. Radiation-induced oxidative stress induces proinflammatory cytokines and is a process that potentiates late effects of fibrosis and intimal proliferation in endothelial vasculature. Breast radiation therapy has changed substantially in recent decades. Several modern technologies exist to improve cardiac avoidance such as deep inspiration breath hold, gating, accelerated partial breast irradiation, and use of modern 3-dimensional planning. Modern outcomes may vary notably from historical long-term cardiac outcomes given the differences in cardiac dose with modern techniques. Methods of quantifying radiation-related cardiotoxicity that correlate with future cardiac risks are needed with current data exploring techniques such as measuring computed tomography coronary artery calcium score, single-photon emission computed tomography imaging, and biomarkers. Placing historical data, dosimetric correlations, and relative cardiac risk in context are key when weighing the benefits of radiotherapy in breast cancer control and survival. Estimating present day cardiac risk in the modern treatment era includes challenges in length of follow-up and the use of confounding cardiotoxic agents such as evolving systemic chemotherapy and targeted therapies. Future directions in both multidisciplinary management and advancing technology in radiation oncology may provide further improvements in patient risk reduction and breast cancer survivorship.

    2014-05-01

    Whether to allow the presence of family members during cardiopulmonary resuscitation (CPR) has been a highly contentious topic in recent years. Even though a great deal of evidence and professional guidelines support the option of family presence during resuscitation (FPDR), many healthcare professionals still oppose it. One of the main arguments espoused by the latter is that family members should not be allowed for the sake of the patient's best interests, whether it is to increase his chances of survival, respect his privacy or leave his family with a last positive impression of him. In this paper, we examine the issue of FPDR from the patient's point of view. Since the patient requires CPR, he is invariably unconscious and therefore incompetent. We discuss the Autonomy Principle and the Three-Tiered process for surrogate decision making, as well as the Beneficence Principle and show that these are limited in providing us with an adequate tool for decision making in this particular case. Rather, we rely on a novel principle (or, rather, a novel specification of an existing principle) and a novel integrated model for surrogate decision making. We show that this model is more satisfactory in taking the patient's true wishes under consideration and encourages a joint decision making process by all parties involved. PMID:23557910

    2014-01-01

    Acute pancreatitis (AP) is a frequent disease with degrees of increasing severity responsible for high morbidity. Despite continuous improvement in care, mortality remains significant. Because hypovolemia, together with microcirculatory dysfunction lead to poor outcome, fluid therapy remains a cornerstone of the supportive treatment. However, poor clinical evidence actually support the aggressive fluid therapy recommended in recent guidelines since available data are controversial. Fluid management remains unclear and leads to current heterogeneous practice. Different strategies may help to improve fluid resuscitation in AP. On one hand, integration of fluid therapy in a global hemodynamic resuscitation has been demonstrated to improve outcome in surgical or septic patients. Tailored fluid administration after early identification of patients with high-risk of poor outcome presenting inadequate tissue oxygenation is a major part of this strategy. On the other hand, new decision parameters have been developed recently to improve safety and efficiency of fluid therapy in critically ill patients. In this review, we propose a personalized strategy integrating these new concepts in the early fluid management of AP. This new approach paves the way to a wide range of clinical studies in the field of AP. PMID:25473163

    We studied alterations of chest geometry during conventional cardiopulmonary resuscitation in anesthetized immature swine. Pulsatile force was applied to the sternum in increments to determine the effects of increasing compression on chest geometry and intrathoracic vascular pressures. In 2-wk- and 1-mo-old piglets, permanent changes in chest shape developed due to incomplete recoil of the chest along the anteroposterior axis, and large intrathoracic vascular pressures were generated. In 3-mo-old animals, permanent chest deformity did not develop, and large intrathoracic vascular pressures were not produced. We propose a theoretical model of the chest as an elliptic cylinder. Pulsatile displacement along the minor axis of an ellipse produces a greater decrease in cross-sectional area than displacement of a circular cross section. As thoracic cross section became less circular due to deformity, greater changes in thoracic volume, and hence pressure, were produced. With extreme deformity at high force, pulsatile displacement became limited, diminishing pressure generation. We conclude that changes in chest geometry are important in producing intrathoracic intravascular pressure during conventional cardiopulmonary resuscitation in piglets. PMID:3610916

    Full Text Available Mechanical forces are an essential contributor to and unavoidable component of cardiac formation, both inducing and orchestrating local and global molecular and cellular changes. Experimental animal studies have contributed substantially to understanding the mechanobiology of heart development. More recent integration of high-resolution imaging modalities with computational modeling has greatly improved our quantitative understanding of hemodynamic flow in heart development. Merging these latest experimental technologies with molecular and genetic signaling analysis will accelerate our understanding of the relationships integrating mechanical and biological signaling for proper cardiac formation. These advances will likely be essential for clinically translatable guidance for targeted interventions to rescue malforming hearts and/or reconfigure malformed circulations for optimal performance. This review summarizes our current understanding on the levels of mechanical signaling in the heart and their roles in orchestrating cardiac development.

    Full Text Available Abstract Background Healthcare professionals have shown concern about performing mouth-to-mouth ventilation due to the risks to themselves with the procedure. However, little is known about healthcare professionals' fears and attitudes to start CPR and the impact of training. Objective To examine whether there were any changes in the attitudes among healthcare professionals to performing CPR from before to after training. Methods Healthcare professionals from two Swedish hospitals were asked to answer a questionnaire before and after training. The questions were relating to physical and mental discomfort and attitudes to CPR. Statistical analysis used was generalized McNemar's test. Results Overall, there was significant improvement in 10 of 11 items, reflecting various aspects of attitudes to CPR. All groups of health care professionals (physicians, nurses, assistant nurses, and "others" = physiotherapists, occupational therapists, social welfare officers, psychologists, biomedical analysts felt more secure in CPR knowledge after education. In other aspects, such as anxiety prior to a possible cardiac arrest, only nurses and assistant nurses improved. The concern about being infected, when performing mouth to mouth ventilation, was reduced with the most marked reduction in physicians (75%; P Conclusion In this hospital-based setting, we found a positive outcome of education and training in CPR concerning healthcare professionals' attitudes to perform CPR. They felt more secure in their knowledge of cardiopulmonary resuscitation. In some aspects of attitudes to resuscitation nurses and assistant nurses appeared to be the groups that were most markedly influenced. The concern of being infected by a disease was low.

    While therapeutic hypothermia improves the outcomes of individuals in cardiac arrest, the hemodynamic responses and mechanisms which underlie hypothermia-induced cardioprotection are not fully understood. Therefore, we investigated the mechanism by which induced hypothermia preserves cardiac function and protects against mitochondrial damage following cardiac arrest. Cardiac arrest was induced in adult male Wistar rats by asphyxiation for 8.5 min. Following resuscitation, the animals were randomly assigned to a hypothermia (32 °C) or normothermia (37 °C) group. Monitoring results showed that cardiac output at the fourth hour after resuscitation was significantly better in rats treated with hypothermia when compared to rats treated with normothermia (P < 0.01). Examinations by transmission electron microscopy showed that mitochondria in the left ventricle of rats in the hypothermia group were significantly less swollen compared to such mitochondria in the normothermia group (P < 0.001). Additionally, opening of mitochondrial permeability transition pores occurred less frequently in the hypothermic group. While complex I/III activity in the electron transport reaction was damaged after cardiac arrest and resuscitation, the degree of injury was ameliorated by hypothermia treatment (P < 0.05). The amount of STAT-3 phosphorylated at tyrosine 705 and its expression in mitochondria were significantly higher under hypothermia treatment compared to normothermia treatment. In vitro studies showed that inhibition STAT-3 activation abolished the ability of hypothermia to protect H9C2 cardiomyocytes against injury produced by simulated ischemia and reperfusion. Therapeutic hypothermia treatment can ameliorate cardiac dysfunction and help preserve both mitochondrial integrity and electron transport activity. PMID:26471891

    The case of an 18-month child is presented, with a picture demonstrating the thoracic trauma, caused from a hand pressure movement, perpetrated with an open right palm, in an attempt to perform an external cardiac massage. The child showed continuous episodes of 'crying spells' that the medical staff considered as benign, but an overprotective and mentally unstable mother kept on violently 'resuscitating' her son during such episodes. The last episode was characterised with a strenuous massage of the thoracic wall, causing evident bruises and leading to a cardiac contusion. The mother who perpetrated the trauma was sentenced for manslaughter, after the accidental character of the event, as well as the severity of her family situation and the precarious living environment of a socially abandoned single-acting parent, were all taken into account. The particular psychopathology of the care giver (mother) and the characteristics of the inflicted thoracic blow are described. PMID:22675032

The medical records of all patients with hypothermic cardiac arrest treated in the ED from January 1, 1988 to January 31, 1999 were retrospectively reviewed. Data collected included initial body temperature, serum potassium, methods of rewarming, return of perfusing rhythm, and morbidity and mortality. Data were analyzed by descriptive methods. Eleven patients were treated in the ED resuscitation room for hypothermic cardiac arrest. Six patients were found in cardiac arrest in the field, one patient arrested during transport, and four patients arrested after ED arrival. The average initial temperature was 79.1 degrees F (range 69.0 degrees F to 86.7 degrees F). Seven patients received an ED thoracotomy with internal cardiac massage and warm mediastinal irrigation. Four patients had airway management in the ED and then direct transport to the operating room for cardiac bypass rewarming. Three of the seven patients who received an ED thoracotomy subsequently went to intraoperative cardiac bypass rewarming. Five of the seven (71.4%) patients who received an ED thoracotomy survived, versus none of the four patients (0%) who went directly to intraoperative cardiac bypass. A direct comparison of immediate ED thoracotomy versus intraoperative cardiac bypass without ED thoracotomy is cautiously made as this was an unmatched and nonrandomized study. Three of the surviving patients underwent intraoperative cardiac bypass rewarming after receiving an ED thoracotomy. In two of these patients a perfusing rhythm had been established after thoracotomy in the ED and before transport to the operating room for cardiac bypass. Only one of seven (14.3%) patients who arrested prehospital survived versus four of four (100%) who arrested in the ED. ED thoracotomy with internal cardiac massage and mediastinal irrigation rewarming is effective in the management

    Objective Cardiopulmonary resuscitation (CPR) training in schools is recommended to increase bystander CPR and thereby survival of out-of-hospital cardiac arrest, but despite mandating legislation, low rates of implementation have been observed in several countries, including Denmark. The purpose of the study was to explore barriers to implementation of CPR training in Danish secondary schools. Design A qualitative study based on individual interviews and focus groups with school leadership and teachers. Thematic analysis was used to identify regular patterns of meaning both within and across the interviews. Setting 8 secondary schools in Denmark. Schools were selected using strategic sampling to reach maximum variation, including schools with/without recent experience in CPR training of students, public/private schools and schools near to and far from hospitals. Participants The study population comprised 25 participants, 9 school leadership members and 16 teachers. Results School leadership and teachers considered it important for implementation and sustainability of CPR training that teachers conduct CPR training of students. However, they preferred external instructors to train students, unless teachers acquired the CPR skills which they considered were needed. They considered CPR training to differ substantially from other teaching subjects because it is a matter of life and death, and they therefore believed extraordinary skills were required for conducting the training. This was mainly rooted in their insecurity about their own CPR skills. CPR training kits seemed to lower expectations of skill requirements to conduct CPR training, but only among those who were familiar with such kits. Conclusions To facilitate implementation of CPR training in schools, it is necessary to have clear guidelines regarding the required proficiency level to train students in CPR, to provide teachers with these skills, and to underscore that extensive skills are not required to

    Survival from pediatric cardiac arrest due to trauma has been reported to be 0.0%-8.8%. Some argue that resuscitation efforts in the case of trauma-related cardiac arrests are futile. We describe a successful outcome in the case of a child who suffered cardiac arrest caused by external traumatic airway obstruction. Our case illustrates how to deal with pediatric traumatic cardiac arrests in an out-of-hospital environment. It also illustrates how good clinical treatment in these situations may be supported by correct treatment after hospital admission when it is impossible to ventilate the patient to provide sufficient oxygen delivery to vital organs. This case relates to a lifeless child of 3-5 years, blue, and trapped by an electrically operated garage door. The first ambulance arrived to find several men trying to bend the frame and the door apart in order to extricate the child, who was hanging in the air with head and neck squeezed between the horizontally-moving garage door and the vertical door frame. One paramedic found a car jack and used it to push the door and the frame apart, allowing the lifeless child to be extricated. Basic life support was then initiated. Intubation was performed by the anesthesiologist without drugs. With FiO2 1.0 the first documented SaO2 was <50%. Restoration of Spontaneous Circulation was achieved after thirty minutes, and she was transported to the hospital. After a few hours she was put on venous-arterial ECMO for 5.5 days and discharged home after two months. Outpatient examinations during the rest of 2013 were positive, and the child found not to be suffering from any injuries, either physical or mental. The last follow-up in October 2014 demonstrated she had made a 100% recovery and she started school in August 2014. PMID:26930137

    Full Text Available Objective. To evaluate variation in airway management strategies in one suburban emergency medical services system treating patients experiencing out-of-hospital cardiac arrest (OHCA. Method. Retrospective chart review of all adult OHCA resuscitation during a 13-month period, specifically comparing airway management decisions. Results. Paramedics demonstrated considerable variation in their approaches to airway management. Approximately half of all OHCA patients received more than one airway management attempt (38/77 [49%], and one-quarter underwent three or more attempts (25/77 [25%]. One-third of patients arrived at the emergency department with a different airway device than initially selected (25/77 [32%]. Conclusion. This study confirmed our hypothesis that paramedics’ selection of ventilation strategies in cardiac arrest varies considerably. This observation raises concern because airway management diverts time and energy from interventions known to improve outcomes in OHCA management, such as cardiopulmonary resuscitation and defibrillation. More research is needed to identify more focused airway management strategies for prehospital care providers.

    Background: Adequate ventilation is the key to successful neonatal resuscitation. Positive pressure ventilation (PPV) is initiated with manual ventilation devices via face masks. These devices may be used with a manometer to measure airway pressures delivered. The expiratory tidal volume measured at the mask (VTE(mask)) is a good estimate of the tidal volume delivered during simulated neonatal resuscitation. Aim: To assess the effect of viewing a manometer on the peak inspiratory pressures used, the volume delivered, and leakage from the face mask during PPV with two manual ventilation devices in a model of neonatal resuscitation. Methods: Participants gave PPV to a modified resuscitation mannequin using a Laerdal infant resuscitator and a Neopuff infant resuscitator at specified pressures ensuring adequate chest wall excursion. Each participant gave PPV to the mannequin with each device twice, viewing the manometer on one occasion and unable to see the manometer on the other. Data from participants were averaged for each device used with the manometer and without the manometer separately. Results: A total of 7767 inflations delivered by the 18 participants were recorded and analysed. Peak inspiratory pressures delivered were lower with the Laerdal device. There were no differences in leakage from the face mask or volumes delivered. Whether or not the manometer was visible made no difference to any measured variable. Conclusions: Viewing a manometer during PPV in this model of neonatal resuscitation does not affect the airway pressure or tidal volumes delivered or the degree of leakage from the face mask.

    Effective resuscitation is critical in reducing mortality and morbidity rates of patients with acute burns. To this end, guidelines and formulas have been developed to define infusion rates and volume requirements during the first 48 hours postburn. Even with these standardized resuscitation guidelines, however, over- and under-resuscitation are not uncommon. Two approaches to adjust infusion rate are decision-assist and closed-loop algorithms based on levels of urinary output. Specific decision assist guidelines or a closed-loop system using computer-controlled feedback technology that supplies automatic control of infusion rates can potentially achieve better control of urinary output. In a properly designed system, closed-loop control has the potential to provide more accurate titration rates, while lowering the incidence of over- and under-resuscitation. Because the system can self-adjust based on monitoring inputs, the technology can be pushed to environments such as combat zones where burn resuscitation expertise is limited. A closed-loop system can also assist in the management of mass casualties, another scenario in which medical expertise is often in short supply. This article reviews the record of fluid balance of contemporary burn resuscitation and approaches, as well as the engineering efforts, animal studies, and algorithm development of our most recent autonomous systems for burn resuscitation.

    Full Text Available Abstract Background Neuron specific enolase (NSE has repeatedly been evaluated for neurological prognostication in patients after cardiac arrest. However, it is unclear whether current guidelines for NSE cutoff levels also apply to cardiac arrest patients treated with hypothermia. Thus, we investigated the prognostic significance of absolute NSE levels and NSE kinetics in cardiac arrest patients treated with hypothermia. Methods In a prospective study of 35 patients resuscitated from cardiac arrest, NSE was measured daily for four days following admission. Outcome was assessed at ICU discharge using the CPC score. All patients received hypothermia treatment for 24 hours at 33°C with a surface cooling device according to current guidelines. Results The cutoff for absolute NSE levels in patients with unfavourable outcome (CPC 3-5 72 hours after cardiac arrest was 57 μg/l with an area under the curve (AUC of 0.82 (sensitivity 47%, specificity 100%. The cutoff level for NSE kinetics in patients with unfavourable outcome (CPC 3-5 was an absolute increase of 7.9 μg/l (AUC 0.78, sensitivity 63%, specificity 100% and a relative increase of 33.1% (AUC 0.803, sensitivity 67%, specificity 100% at 48 hours compared to admission. Conclusion In cardiac arrest patients treated with hypothermia, prognostication of unfavourable outcome by NSE kinetics between admission and 48 hours after resuscitation may be superior to prognostication by absolute NSE levels.

    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

    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.

    Full Text Available Aim: This study was undertaken to assess the demographics, clinical parameters and outcomes of patients undergoing cardiopulmonary resuscitation (CPR, by the code blue team at our center to compare with other centers. Materials and Methods: Data were collected retrospectively from all adult patients who underwent CPR at our hospital from 2007 to 2008. CPR was performed on 290 patients and it was given 313 times. Clinical outcomes of interest were survival at the end of CPR and survival at discharge from the hospital. Factors associated with survival were evaluated via binomial and chi square-tests. Results: Of the 290 patients included, 95 patients (30.4% had successful CPR. However, only 35 patients (12% were alive at discharge. The majority requiring CPR were above 60 years of age (61.7%. Males required CPR more than females. There were 125 women (43.1% and 165 males (56.9% aged 3 to 78 (average 59.6 years. Majority (179 of the cases (61.7% were above 60 years of age. Regarding the various wards, 54 cases (17.3% were in the internal medicine ward, 63 cases (20.1% in the surgery ward, 1 case (0.3% in the clinic, 11 cases (3.5% in the paraclinic, 116 cases (37.1% in the emergency (ER, 55 cases (17.5% in the Intensive Care Unit (ICU and Coronary Care Unit (CCU, and 13 cases (4.2% were in other wards. Cardiac massage was done in 133 cases (42.5%, defibrillation only via electroshock 3 cases (1%, and both were used in177 cases (56.5%. The ER had the most cases of CPR. Both cardiac massage and electroshock defibrillation were needed in most cases. Conclusion: In-hospital CPR for cardiopulmonary arrest was associated with 30.4% success at our center at the end of CPR but only 12% were alive at discharge. Duration of CPR> 10 minutes was predictive of significantly decreased survival to discharge.

    Full Text Available Introduction: The objective of this study was to determine the thermal injury fluid resuscitation protocols at intensive care units (ICUs in the United Kingdom and Ireland. Materials and methods: A telephone questionnaire was designed to survey the fluid resuscitation protocols of ICUs at all hospitals with plastic/burn surgery departments in the British Isles in 2010. The feedback from the questionnaire was from the senior nurse in charge of the ICUs. Results: 32/64 (50% of these ICUs had provided care to burns patients. A 100% response from these 32 units was obtained. 71.4% commence fluid resuscitation at 15% total body surface area burn (TBSA, 21.4% at 20% TBSA and 7.1% at 10% TBSA in adults. The estimated resuscitation volume was most often calculated using the Parkland/Modified Parkland formula (87.5% or the Muir and Barclay formula (12.5%. Interestingly, of the ICUs using formulae, two had recently moved from using the Muir and Barclay formula to Parkland formula and one had recently moved from using the Parkland formula to Muir and Barclay formula. Despite this, 37.5% of ICUs using a formula did not rigidly follow it exactly. The most commonly used resuscitation fluid was Ringer’s lactate solution (46.9% and Human Albumin Solution was used in 12.5%. No ICU used red cell concentrate as a first line fluid. 18.8% used a central line. 40.6% ICUs considered changing the IV solution during resuscitation. 78.1% ICUs consider urine output to be the most important factor in modifying resuscitation volumes. 59.4% ICUs calculate a maintenance fluid rate after completion of resuscitation. The endpoint for resuscitation was at 24 h in 46.9% ICUs and at 36 h in 9.4%. 5/32 (16% felt their protocol gave too little and 6/32 (19% felt their protocol gave too much. 59.3% ICUs gave oral/enteral fluids by naso-gastric or naso-jejenal tubes. 21.9% felt that oral/enteral resuscitation worked. Exactly half of the units believed that the formula that they used

    Cardiac transplantation remains the best treatment in advanced heart failure patients with a high risk of death. However, an inadequate supply of donor hearts decreases the likelihood of transplantation for many patients. Ventricular assist devices (VAD) are being increasingly used as a bridge to transplant in patients who may not survive long enough to receive a heart. This expansion in VAD use has been associated with increasing rates of allosensitization in cardiac transplant candidates. A...

    Full Text Available Abstract Background Optimal manual closed chest compressions are difficult to give. A mechanical compression/decompression device, named LUCAS, is programmed to give compression according to the latest international guidelines (2005 for cardiopulmonary resuscitation (CPR. The aim of the present study was to compare manual CPR with LUCAS-CPR. Methods 30 kg pigs were anesthetized and intubated. After a base-line period and five minutes of ventricular fibrillation, manual CPR (n = 8 or LUCAS-CPR (n = 8 was started and run for 20 minutes. Professional paramedics gave manual chest compression's alternating in 2-minute periods. Ventilation, one breath for each 10 compressions, was given to all animals. Defibrillation and, if needed, adrenaline were given to obtain a return of spontaneous circulation (ROSC. Results The mean coronary perfusion pressure was significantly (p Conclusions LUCAS-CPR gave significantly higher coronary perfusion pressure and significantly fewer rib fractures than manual CPR in this porcine model.

  6. Cardiopulmonary resuscitation in the elderly: a clinical and ethical perspective

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    The daily practice of cardiopulmonary resuscitation (CPR) in elderly patients has brought up the attention of outcome research and resource allocation. Determinants to predict survival have been well identified. There has been empirical evidence that CPR is of doubtful utility in the geriatric population, more studies have showed controversial data. Sometimes situations in which CPR needs to be given in the elderly, causes stress to healthcare providers, due to lack of communication of the patient's wishes and the belief that it will not be successful. It is of importance to state that we have the duty to identify on time the patients that will most likely benefit from CPR, and find out the preferences of the same. Whenever it is possible to institute these guidelines, we will avoid patient suffering.

    Objective To compare the effects of vasopressin and adrenaline on cerebral resuscitation in rats. Method Sixty male SD rats were used to set the animal model of cardiac arrest and were randomly (random number) divided into 4 groups (n = 15/group): sham operation group (sham-gro), negative control group (neg-gro), vasopressin group (vas-gro) and adrenaline group (adr-gro). Blood pressure was recorded, and brain tissue samples were obtained. Results There was no significant difference in the recovery rate between vas-gro and adr-gro 30 min after resuscitation (P <0.05). The mean blood pressure in vasgro was higher than that in adr-gro within 30 min (1,2, 5, 10, 20, 30 min) after restoration of spontaneous circulation. The measured MDA, SOD and GSH were significantly different (P < 0.05) between each two groups among vas-gro, sham-gro and adr-gro. Conclusions The recovery rate was similar between vasopressin group and adrenaline group during cardiopulmonary resuscitation in rats. However, vasopressin can to maintain the mean arterial pressure at a higher level after resuscitation, which can the increase the cerebral perfusion and reduce brain cell damage.%目的 比较血管加压素与肾上腺素对大鼠脑复苏效果的研究.方法 60只雄性SD大鼠建立心搏骤停模型,随机(随机数字法)分为4组(n=15/组):假手术组(sham operated group,shamgro)、阴性对照组(neg-gro)、血管加压素组(vas-gro)、肾上腺素组(adr-gro).分别记录血压变化,并取大鼠脑组织标本.结果 在复苏30 min后vas-gro与adr-gro复苏成功率差异无统计学意义(P>0.05);在自主循环恢复的30 min内(1,2,5,10,20,30 min)vas-gro的平均动脉压均高于adr-gro;测得MDA,SOD,GSH的量vas-gro,sham-gro,adr-gro互相之间差异有统计学意义(P<0.05).结论 血管加压素与肾上腺素在大鼠心肺复苏过程中成功率相近,但血管加压素能维持复苏后平均动脉压在较高水平,继而会更好的增加脑灌注,减轻脑细胞损伤.

    Full Text Available Objective. Untrained bystanders usually delivered suboptimal chest compression to victims who suffered from cardiac arrest in out-of-hospital settings. We therefore investigated the hemodynamics and resuscitation outcome of initial suboptimal quality of chest compressions compared to the optimal ones in a porcine model of cardiac arrest. Methods. Fourteen Yorkshire pigs weighted 30 ± 2 kg were randomized into good and poor cardiopulmonary resuscitation (CPR groups. Ventricular fibrillation was electrically induced and untreated for 6 mins. In good CPR group, animals received high quality manual chest compressions according to the Guidelines (25% of animal’s anterior-posterior thoracic diameter during first two minutes of CPR compared with poor (70% of the optimal depth compressions. After that, a 120-J biphasic shock was delivered. If the animal did not acquire return of spontaneous circulation, another 2 mins of CPR and shock followed. Four minutes later, both groups received optimal CPR until total 10 mins of CPR has been finished. Results. All seven animals in good CPR group were resuscitated compared with only two in poor CPR group (P<0.05. The delayed optimal compressions which followed 4 mins of suboptimal compressions failed to increase the lower coronary perfusion pressure of five non-survival animals in poor CPR group. Conclusions. In a porcine model of prolonged cardiac arrest, even four minutes of initial poor quality of CPR compromises the hemodynamics and survival outcome.

    Effective pre-hospital treatment of a person suffering cardiac arrest is a challenging task for the ambulance nurses. The aim of this study was to describe ambulance nurses' experiences of nursing patients suffering cardiac arrest. Qualitative personal interviews were conducted during 2011 in Sweden with seven ambulance nurses with experience of nursing patients suffering cardiac arrests. The interview texts were analyzed using qualitative thematic content analysis, which resulted in the formulation of one theme with six categories. Mutual preparation, regular training and education were important factors in the nursing of patients suffering cardiac arrest. Ambulance nurses are placed in ethically demanding situations regarding if and for how long they should continue cardio-pulmonary resuscitation (CPR) to accord with pre-hospital cardiac guidelines and patients' wishes. When a cardiac arrest patient is nursed their relatives also need the attention of ambulance nurses. Reflection is one way for ambulance nurses to learn from, and talk about, their experiences. This study provides knowledge of ambulance nurses' experiences in the care of people with cardiac arrest. Better feedback about the care given by the ambulance nurses, and about the diagnosis and nursing care the patients received after they were admitted to the hospital are suggested as improvements that would allow ambulance nurses to learn more from their experience. Further development and research concerning the technical equipment might improve the situation for both the ambulance nurses and the patients. Ambulance nurses need regularly training and education to be prepared for saving people's lives and also to be able to make the right decisions. PMID:23577977

    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.

    Full Text Available Health professionals often witness in-hospital episodes of cardiac arrest. The quality of the Cardiopulmonary Resuscitation (CPR depends on the level of theoretical background and practical skills. Purpose: The aim of the present study was to investigate the level of theoretical knowledge of skilled cardiologists and anesthesiologists in the Basic and Advanced Life Support (BLS/ ALS. Material - method: In this study, sample included 240 cardiologists and anesthesiologists, chosen randomly from employers of 17 General Public Hospitals of Athens. For data collection, a questionnaire with 16 theoretical questions was designed, based on the guidelines of the European Resuscitation Council (ERC 2005. Significance level was set at p=≤0,05. The analysis was performed with the Statistical Package IBM SPSS Statistics 19. Results: No statistically significant difference was observed between specialists cardiologists and anesthesiologists in overall performance in theoretical knowledge on the BLS and ALS. Additionally, no statistical significance was observed between the two separate groups of theoretical background. Statistically significant difference was observed among those who had participated in a training seminar in BLS and ALS and those who had not participated (p<0,001. Also, there was statistical significance between the follow-up seminar in BLS/ ALS and specialty for the right answer to the question "which is the right ratio of chest compressions and ventilation", (p<0,001. Conclusions: The level of background knowledge of specialist cardiologists and anesthesiologists in the algorithms of BLS and ALS seem to correlate to the attendance of a training course.

    The evidence regarding specific cardiac perception and discrimination, and its relationship to voluntary cardiac control, is critically reviewed. Studies are considered in three sections, depending on the method used to assess cardiac perception: questionnaire assessment, discrimination procedures, and heartbeat tracking. The heartbeat tracking procedure would appear to suffer least from interpretative difficulties. Recommendations are made regarding the style of analysis used to assess heartbeat perception in such tracking tasks. PMID:348240

  4. 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.

    2016-09-01

    Pathological contraction bands (CB) are recognized as a type of necrosis pattern found in the myocardium. It is well known that CB are induced by cardiopulmonary resuscitation (CPR) with cardiac massage. However, it is not known whether the reperfusion or massage itself causes the formation of CB. We studied 10 cardiac tissues taken from forensic autopsy cases that had not received CPR. We excluded the cases where the cause of death was a cardiac event. After making sections for forensic research, we massaged the left ventricles for 10 minutes. We found CB in all cases with massage performed within 12 hours after death, which is the time frame for supravital reactions. We did not find CB in any cases where more than 24 hours had elapsed since the time of death. Contraction bands were not observed in any sections that were taken before massage. We suggested here that CB induced by CPR were caused by the cardiac massage itself, and that most CPR-induced CB are not contraction band necrosis but rather artifactual CB. PMID:27323278

    Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an adjunct technique for salvaging patients with noncompressible torso hemorrhage. Current REBOA training paradigms require large animals, virtual reality simulators, or human cadavers for acquisition of skills. These training strategies are expensive and resource intensive, which may prevent widespread dissemination of REBOA. We have developed a low-cost, near-physiologic, pulsatile REBOA simulator by connecting an anatomic vascular circuit constructed out of latex and polyvinyl chloride tubing to a commercially available pump. This pulsatile simulator is capable of generating cardiac outputs ranging from 1.7 to 6.8 L/min with corresponding arterial blood pressures of 54 to 226/14 to 121 mmHg. The simulator accommodates a 12 French introducer sheath and a CODA balloon catheter. Upon balloon inflation, the arterial waveform distal to the occlusion flattens, distal pulsation within the simulator is lost, and systolic blood pressures proximal to the balloon catheter increase by up to 62 mmHg. Further development and validation of this simulator will allow for refinement, reduction, and replacement of large animal models, costly virtual reality simulators, and perfused cadavers for training purposes. This will ultimately facilitate the low-cost, high-fidelity REBOA simulation needed for the widespread dissemination of this life-saving technique. PMID:27270855

    Full Text Available Abstract Background Immediate bystander cardiopulmonary resuscitation (CPR significantly improves survival after a sudden cardiopulmonary collapse. This study assessed the basic life support (BLS knowledge and performance of high school students before and after CPR training. Methods This study included 132 teenagers (mean age 14.6 ± 1.4 years. Students completed a two-hour training course that provided theoretical background on sudden cardiac death (SCD and a hands-on CPR tutorial. They were asked to perform BLS on a manikin to simulate an SCD scenario before the training. Afterwards, participants encountered the same scenario and completed a questionnaire for self-assessment of their pre- and post-training confidence. Four months later, we assessed the knowledge retention rate of the participants with a BLS performance score. Results Before the training, 29.5% of students performed chest compressions as compared to 99.2% post-training (P P Conclusions BLS training in high school seems highly effective considering the minimal amount of previous knowledge the students possess. We observed significant improvement and a good retention rate four months after training. Increasing the number of trained students may minimize the reluctance to conduct bystander CPR and increase the number of positive outcomes after sudden cardiopulmonary collapse.

    Attin, Mina; Tucker, Rebecca G; Carey, Mary G

    2016-09-01

    Nonshockable rhythms, including pulseless electrical activity (PEA) and asystole, precede more than 70% of in-hospital cardiac arrests (I-HCA). Compared with shockable rhythms (ventricular fibrillation and ventricular tachycardia), nonshockable rhythms have higher mortality and morbidity. Therefore, investigating the underlying mechanisms of these arrhythmias to improve the quality of care and outcome for patients who suffer cardiac arrest is a priority. As the first responders to I-HCA, nurses must have the proper knowledge and training to provide timely and efficient cardiopulmonary resuscitation therapy. This article provides an overview of nonshockable cardiac arrhythmias preceding I-HCA as a means of addressing the gap between science and clinical practice. PMID:27484665

  14. Transplanting hearts after death measured by cardiac criteria: the challenge to the dead donor rule.

    Science.gov (United States)

    Veatch, Robert M

    2010-06-01

    The current definition of death used for donation after cardiac death relies on a determination of the irreversible cessation of the cardiac function. Although this criterion can be compatible with transplantation of most organs, it is not compatible with heart transplantation since heart transplants by definition involve the resuscitation of the supposedly "irreversibly" stopped heart. Subsequently, the definition of "irreversible" has been altered so as to permit heart transplantation in some circumstances, but this is unsatisfactory. There are three available strategies for solving this "irreversibility problem": altering the definition of death so as to rely on circulatory irreversibility, rather than cardiac; defining death strictly on the basis of brain death (either whole-brain or more pragmatically some higher brain criteria); or redefining death in traditional terms and simultaneously legalizing some limited instances of medical killing to procure viable hearts. The first two strategies are the most ethically justifiable and practical. PMID:20439354

    Cardiopulmonary resuscitation (CPR) is an effective way to rescue patients with cardiac arrest (CA) whose incidence rate has been increasing with the increase of cardiovascular and cerebrovascular diseases in recent years. After 50 years of exploration and practice of CPR, the survival rate on discharge of CA is far from satisfactory. While more efforts are being made to perfect CPR approach, the experience should be summarized and the misunderstanding should be avoided. We suggest that the main misunderstanding of CPR lies in stereotyped CPR procedure, CPR ventilation, CPR compression, open chest cardiac massage, CPR access, CPR back veneer and time limit are not adaptable to practice. We should work out a better method to guide CPR application in clinical practice.%心脏骤停威胁人们的生命健康,且近年随着心脑血管疾病增加其发病率逐渐攀升,心肺复苏(cardiopulmonaryresuscitation,CPR)作为抢救心脏骤停的有效方法,经过50余年的探索实践,患者的生存出院率仍不理想,故在发掘完善新方法的同时,亦应不断总结经验教训,找出CPR进程中的误区,笔者认为当前临床主要存在CPR程序“刻板化”、CPR通气“死腔化”、CPR按压“形式化”、CPR开胸“概念化”、CPR通路“单一化”、CPR背板“无声化”及CPR时限“教条化”,并结合经验积极尝试修正,以指导临床正确把握并实施CPR.

    A well-functioning heart requires a constant supply of a balanced mixture of nutrients to be used for the production of adequate amounts of adenosine triphosphate, which is the main energy source for most cellular functions. Defects in cardiac energy metabolism are linked to several myocardial disorders. MRS can be used to study in vivo changes in cardiac metabolism noninvasively. MR techniques allow repeated measurements, so that disease progression and the response to treatment or to a lifestyle intervention can be monitored. It has also been shown that MRS can predict clinical heart failure and death. This article focuses on in vivo MRS to assess cardiac metabolism in humans and experimental animals, as experimental animals are often used to investigate the mechanisms underlying the development of metabolic diseases. Various MR techniques, such as cardiac (31) P-MRS, (1) H-MRS, hyperpolarized (13) C-MRS and Dixon MRI, are described. A short overview of current and emerging applications is given. Cardiac MRS is a promising technique for the investigation of the relationship between cardiac metabolism and cardiac disease. However, further optimization of scan time and signal-to-noise ratio is required before broad clinical application. In this respect, the ongoing development of advanced shimming algorithms, radiofrequency pulses, pulse sequences, (multichannel) detection coils, the use of hyperpolarized nuclei and scanning at higher magnetic field strengths offer future perspective for clinical applications of MRS.

    2011-01-01

    Full Text Available Abstract Background Advances in resuscitation science have dramatically improved survival rates following cardiac arrest. However, about 60% of adults that regain spontaneous circulation die before leaving the hospital. Recently it has been shown that inducing hypothermia in cardiac arrest survivors immediately following their arrival in hospital can dramatically improve both overall survival and neurological outcomes. Despite the strong evidence for its efficacy and the apparent simplicity of this intervention, recent surveys show that therapeutic hypothermia is delivered inconsistently, incompletely, and often with delay. Methods and design This study will evaluate a multi-faceted knowledge translation strategy designed to increase the utilization rate of induced hypothermia in survivors of cardiac arrest across a network of 37 hospitals in Southwestern Ontario, Canada. The study is designed as a stepped wedge randomized trial lasting two years. Individual hospitals will be randomly assigned to four different wedges that will receive the active knowledge translation strategy according to a sequential rollout over a number of time periods. By the end of the study, all hospitals will have received the intervention. The primary aim is to measure the effectiveness of a multifaceted knowledge translation plan involving education, reminders, and audit-feedback for improving the use of induced hypothermia in survivors of cardiac arrest presenting to the emergency department. The primary outcome is the proportion of eligible OHCA patients that are cooled to a body temperature of 32 to 34°C within six hours of arrival in the hospital. Secondary outcomes will include process of care measures and clinical outcomes. Discussion Inducing hypothermia in cardiac arrest survivors immediately following their arrival to hospital has been shown to dramatically improve both overall survival and neurological outcomes. However, this lifesaving treatment is

    2015-09-01

    Despite significant advances in battery longevity, lead performance, and programming features since the first implanted permanent pacemaker was developed, the basic design of cardiac pacemakers has remained relatively unchanged over the past 50 years. Because of inherent limitations in their design, conventional (transvenous) pacemakers are prone to multiple potential short- and long-term complications. Accordingly, there has been intense interest in a system able to provide the symptomatic and potentially lifesaving therapies of cardiac pacemakers while mitigating many of the risks associated with their weakest link-the transvenous lead. Leadless cardiac pacing represents the future of cardiac pacing systems, similar to the transition that occurred from the use of epicardial pacing systems to the familiar transvenous systems of today. This review summarizes the current evidence and potential benefits of leadless pacing systems, which are either commercially available (in Europe) or under clinical investigation. PMID:26337997

    2015-01-01

    Background:Morbidity and mortality after resuscitation largely depend on the recovery of brain function.Ventricular fibrillation cardiac arrest (VFCA) and asphyxial cardiac arrest (ACA) are the two most prevalent causes of sudden cardiac death.Up to now,most studies have focused on VFCA.However,results from the two models have been largely variable.So,it is necessary to characterize the features of postresuscitation cerebral metabolism of both models.Methods:Forty-four Wuzhishan miniature inbred pigs were randomly divided into three groups:18 for VFCA group,ACA group,respectively,and other 8 for sham-operated group (SHAM).VFCA was induced by programmed electric stimulation,andACA was induced by endotracheal tube clamping.After 8 min without treatment,standard cardiopulmonary resuscitation (CPR) was initiated.Following neurological deficit scores (NDS) were evaluated at 24 h after achievement of spontaneous circulation,cerebral metabolism showed as the maximum standardized uptake value (SUVmax) was measured by 18F-fluorodeoxyglucose positron emission tomography/computed tomography.Levels of serum markers of brain injury,neuron specific enolase (NSE),and S100β were quantified with an enzyme-linked immunosorbent assay.Results:Compared with VFCA group,fewer ACA animals achieved restoration of spontaneous circulation (61.1% vs.94.4%,P < 0.01) and survived 24-h after resuscitation (38.9% vs.77.8%,P < 0.01) with worse neurological outcome (NDS:244.3 ± 15.3 vs.168.8 ± 9.71,P < 0.01).The CPR duration of ACA group was longer than that of VFCA group (8.1 ± 1.2 min vs.4.5 ± 1.1 min,P < 0.01).Cerebral energy metabolism showed as SUVmax in ACA was lower than in VFCA (P < 0.05 or P < 0.01).Higher serum biomarkers of brain damage (NSE,S100β) were found inACA than VFCA after resuscitation (P < 0.01).Conclusions:Compared with VFCA,ACA causes more severe cerebral metabolism injuries with less successful resuscitation and worse neurological outcome.

    Background Physicians are responsible for making decisions about the do not resuscitate (DNR) order of patients; however, most of them are faced with some uncertainty in decision making and ethical aspects. Moreover, there are differences on decision making related to the DNR order among physicians, which may be related to the different attitudes toward this issue. Considering the lack of information, this study was performed to investigate doctors’ attitude about DNR order for patients in their final phases of life. Methods In a descriptive–analytical study, 152 physicians were enrolled as quota sampling subjects from educational hospitals affiliated to the Kermanshah University of Medical Sciences. The tool used was a researcher-developed questionnaire. Data were analyzed using SPSS 16 software by descriptive and inferential statistics. Results The mean of attitude toward DNR was 3.22, for which the univariate t-test showed a significant positive attitude toward DNR (P=0.002); the mean of attitude number toward DNR was higher in physicians with higher education level (P=0.002). But this difference was not found in terms of age group, sex, and experiences in participating in DNR decisions. Conclusion Due to the positive attitude of doctors toward DNR orders and lack of identified guidance, clear guidelines that comply with the Iranian Islamic culture are necessary to be established. Implementing this directive requires comprehensive training to various groups, including patients, doctors, nurses, administrators, and policy makers of the health system. PMID:27418832

A retrospective study was performed of 28 patients who had ERRT at St. Elizabeth Hospital Medical Center, Youngstown, Ohio, during the 4 years from July 1985 through June 1989. The prognostic factors analyzed included mechanism and site of injury, signs of life (SOL), vital signs (VS), age, gender, and prehospital care. The overall survival rate of ERRT was 7% (2 of 28 patients). The survival rate was 18% (2 of 11 patients) with penetrating trauma, and 0% (none of 17 patients) with blunt trauma. The best survival rate was 66% in the subgroup of patients with penetrating trauma and SOL present at the scene and in the emergency room (ER), (two of three patients). Our observations were combined with those of 23 studies from the literature involving 2294 trauma patients who had ERRT. Using meta-analysis, the survival rate was 11% overall. Improved survival was noted for patients with penetrating trauma compared with patients with blunt trauma (14% vs. 2%, p ERRTs performed by 41% without decreasing the number of neurologically intact survivors.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1464921

    Objectives. Studies have shown that healthcare personnel hesitate to perform defibrillation due to individual or organisational attitudes. We aimed to assess trainers' attitudes towards cardiopulmonary resuscitation and defibrillation (CPR-D), Current Care Guidelines, and associated training. Methods. A questionnaire was distributed to CPR trainers attending seminars in Finland (N = 185) focusing on the updated national Current Care Guidelines 2011. The questions were answered using Likert scale (1 = totally disagree, 7 = totally agree). Factor loading of the questionnaire was made using maximum likelihood analysis and varimax rotation. Seven scales were constructed (Hesitation, Nurse's Role, Nontechnical Skill, Usefulness, Restrictions, Personal, and Organisation). Cronbach's alphas were 0.92–0.51. Statistics were Student's t-test, ANOVA, stepwise regression analysis, and Pearson Correlation. Results. The questionnaire was returned by 124/185, 67% CPR trainers, of whom two-thirds felt that their undergraduate training in CPR-D had not been adequate. Satisfaction with undergraduate defibrillation training correlated with the Nontechnical Skills scale (p Nurse's Role (p CPR trainers and some feel uncertain of defibrillation. The train-the-trainers courses and undergraduate medical education should focus more on practical scenarios with defibrillators and nontechnical skills. PMID:27144027

    Background Despite recovery of hemodynamics by fluid resuscitation after hemorrhage, development of the systemic inflammatory response and multiple organ dysfunction syndromes can nonetheless lead to death. Minocycline and doxycycline are tetracycline derivatives that are protective in models of hypoxic, ischemic and oxidative stress. Our Aim was to determine whether minocycline and doxycycline protect liver and kidney and improve survival in a mouse model of hemorrhagic shock and resuscitation. Methods Mice were hemorrhaged to 30 mm Hg for 3 h and then resuscitated with shed blood followed by half the shed volume of lactated Ringer's solution containing tetracycline (10 mg/kg), minocycline (10 mg/kg), doxycycline (5 mg/kg) or vehicle. For pre-plus post-treatment, drugs were administered intraperitoneally prior to hemorrhage followed by second equal dose in Ringer's solution after blood resuscitation. Blood and tissue were harvested after 6 h. Results Serum alanine aminotransferase (ALT) increased to 1988 and 1878 U/L after post-treatment with vehicle and tetracycline, respectively, whereas minocycline and doxycycline post-treatment decreased ALT to 857 and 863 U/L. Pre-plus post-treatment with minocycline and doxycycline also decreased ALT to 849 and 834 U/L. After vehicle, blood creatinine increased to 279 μM, which minocycline and doxycycline post-treatment decreased to 118 and 112 μM. Minocycline and doxycycline pre- plus post-treatment decreased creatinine similarly. Minocycline and doxycycline also decreased necrosis and apoptosis in liver and apoptosis in both liver and kidney, the latter assessed by TUNEL and caspase-3 activation. Lastly after 4.5 h of hemorrhage followed by resuscitation, minocycline and doxycycline (but not tetracycline) post-treatment improved 1-week survival from 38%(vehicle) to 69% and 67%, respectively. Conclusion Minocycline and doxycycline were similarly protective when given before as after blood resuscitation and might therefore

    Background Seventeen million births occur in China each year.Neonatal mortality is the leading cause of under 5-year-old child deaths,and intrapartum-related injury accounts for much of mental retardation in young children.The Chinese Ministry of Health sought to improve infant and child survival through a nationwide initiative to have at least one person trained in neonatal resuscitation at every birth.The aim of the current study was to evaluate the impact of China Neonatal Resuscitation Program (NRP) on policy and infrastructure changes and its effectiveness in decreasing the incidence of mortality among newborn infants.Methods The Chinese NRP incorporated policy change,professional education,and creation of a sustainable health system infrastructure for resuscitation.Multidisciplinary teams from all 31 provinces and municipal states disseminated NRP in a train-the-trainer cascade.The intervention targeted 20 provinces with high neonatal mortality and programs to reduce maternal mortality.Program evaluation data came from 322 representative hospitals in those provinces.Results Changes in policy permitted midwives to initiate resuscitation and required resuscitation training for licensure.From 2004 through 2009 more than 110659 professionals received NRP training in the 20 target provinces,with 94% of delivery facilities and 99% of counties reached.Intrapartum-related deaths in the delivery room decreased from 7.5 to 3.4per 10000 from 2003 to 2008,and the incidence of Apgar ≤7 at 1 minute decreased from 6.3% to 2.9%.Conclusions The Chinese NRP achieved policy changes promoting resuscitation,trained large numbers of professionals,and contributed to reduction in delivery room mortality.Improved adherence to the resuscitation algorithm,extension of training to the township level,and coverage of births now occurring outside health facilities can further increase the number of lives saved.

    Organ injury caused by ischaemia and anoxia during prolonged cardiac arrest is compounded by reperfusion injury that occurs when spontaneous circulation is restored. Mild hypothermia (32-35 degrees C) is neuroprotective through several mechanisms, including suppression of apoptosis, reduced production of excitotoxins and free radicals, and anti-inflammatory actions. Experimental studies show that hypothermia is more effective the earlier it is started after return of spontaneous circulation (ROSC). Two randomised clinical trials show improved survival and neurological outcome in adults who remained comatose after initial resuscitation from prehospital VF cardiac arrest, and who were cooled after ROSC. Different strategies can be used to induce hypothermia. Optimal timing of therapeutic hypothermia for cardiac ischaemia is unknown. In patients who failed to respond to standard cardiopulmonary resuscitation, intra-arrest cooling using ice-cold intravenous (i.v.) fluid improved the chance of survival. Recently, fasudil, a Rho kinase inhibitor, was reported to prevent cerebral ischaemia in vivo by increasing cerebral blood flow and inhibiting inflammatory responses. In future, two different kinds of protective therapies, BCL-2 overexpression and hypothermia,will both inhibit aspects of apoptotic cell death cascades, and that combination treatment can prolong the temporal "therapeutic window" for gene therapy.

    Full Text Available Abstract Cardiac tumours are benign or malignant neoplasms arising primarily in the inner lining, muscle layer, or the surrounding pericardium of the heart. They can be primary or metastatic. Primary cardiac tumours are rare in paediatric practice with a prevalence of 0.0017 to 0.28 in autopsy series. In contrast, the incidence of cardiac tumours during foetal life has been reported to be approximately 0.14%. The vast majority of primary cardiac tumours in children are benign, whilst approximately 10% are malignant. Secondary malignant tumours are 10–20 times more prevalent than primary malignant tumours. Rhabdomyoma is the most common cardiac tumour during foetal life and childhood. It accounts for more than 60% of all primary cardiac tumours. The frequency and type of cardiac tumours in adults differ from those in children with 75% being benign and 25% being malignant. Myxomas are the most common primary tumours in adults constituting 40% of benign tumours. Sarcomas make up 75% of malignant cardiac masses. Echocardiography, Computing Tomography (CT and Magnetic Resonance Imaging (MRI of the heart are the main non-invasive diagnostic tools. Cardiac catheterisation is seldom necessary. Tumour biopsy with histological assessment remains the gold standard for confirmation of the diagnosis. Surgical resection of primary cardiac tumours should be considered to relieve symptoms and mechanical obstruction to blood flow. The outcome of surgical resection in symptomatic, non-myxomatous benign cardiac tumours is favourable. Patients with primary cardiac malignancies may benefit from palliative surgery but this approach should not be recommended for patients with metastatic cardiac tumours. Surgery, chemotherapy and radiotherapy may prolong survival. The prognosis for malignant primary cardiac tumours is generally extremely poor.

    Plasma expanders (PEs) are administered fluids to replace blood volume when massive blood loss has occured. Maltodextrin from tapioca starch was selected as a study candidate to prepare a colloid PE due to an uncomplicated production process. The formulations of mixture between tapioca maltodextrin and 0.9 % sodium chloride solution were prepared and then characterized. This was to investigate the effects of a dextrose equivalent (DE) and the concentration on the physical properties. Storage stability of each formulation was also determined and compared with clinically used PE [6 % hydroxyethyl starch (HES), 130/0.4]. The effects on the circulatory system in hamsters with hemorrhagic shock and resuscitation using prepared PE were also investigated. The results showed that low DE value led to high retrogradation, turbidity and viscosity but low colloid osmotic pressure and poor solubility. Among the prepared solutions, tapioca maltodextrin with DE6 at 10 % w/v concentration had comparable properties with 6 % HES 130/0.4. Animals resuscitated with 10 % DE6 PE had improved mean arterial blood pressure similar to those resuscitated with 6 % HES 130/0.4. However, several parameters in animals resuscitated with 10 % DE6 PE were lower than those resuscitated with 6 % HES 130/0.4, i.e., heart rate, functional capillary density. Therefore, if using tapioca maltodextrin for PE, some properties have to be considered and efficiently optimized. PMID:27015687

    Early resuscitation of septic shock patients reduces the sepsis-related morbidity and mortality. The main goals of septic shock resuscitation include volemic expansion, maintenance of adequate tissue perfusion and oxygen delivery, guided by central venous pressure, mean arterial pressure, mixed or central venous oxygen saturation and arterial lactate levels. An aggressive fluid resuscitation, possibly in association with vasopressors, inotropes and red blood cell concentrate transfusion may be necessary to achieve those hemodynamic goals. Nonetheless, even though fluid administration is one of the most common interventions offered to critically ill patients, the most appropriate type of fluid to be used remains controversial. According to recently published clinical trials, crystalloid solutions seem to be the most appropriate type of fluids for initial resuscitation of septic shock patients. Balanced crystalloids have theoretical advantages over the classic solutions, but there is not enough evidence to indicate it as first-line treatment. Additionally, when large amounts of fluids are necessary to restore the hemodynamic stability, albumin solutions may be a safe and effective alternative. Hydroxyethyl starches solutions must be avoided in septic patients due to the increased risk of acute renal failure, increased need for renal replacement therapy and increased mortality. Our objective was to present a narrative review of the literature regarding the major types of fluids and their main drawbacks in the initial resuscitation of the septic shock patients.

    Objective: To investigate the therapeutic effect of cisapride on gastric injury following hemorrhagic shock resuscitation.Methods: 108 Wistar rats weighing (200 g±30 g) were randomly divided into a sham shock (SS) group (n=36), a hemorrhagic shock resuscitation (HS) group (n=36) and a hemorrhagic shock cisapride treated (HSC) group (n=36). Sampling at 1, 2 and 4 hours after resuscitation was done and 6 samples for each observation item were taken. The gastric blood flow volume was measured by isotope label biological microglobulin. Gastric pHi, gastric emptying, MDA and Na+-K+-ATPase of gastric mucosa were measured.Results: In the HSC group, the relative residual rate of gastric pigment decreased significantly, the gastric blood flow volume elevated; gastric pHi increased significantly at 2 hours; the level of mucosal MDA decreased at 4 hours, the activity of Na+-K+-ATPase increased and the lactic acid level in the portal vein decreased significantly compared to the HS group.Conclusions: After hemorrhagic shock resuscitation, cisapride contained the following functions,1) promoting gastric emptying, 2) increasing the blood flow of gastric blood flow volume and gastric pHi, 3) depressing the lactic acid concentration of the portal vein and improving MDA volume and Na+-K+ -ATPase activity of gastric mucosa. It suggests that after comple menting effective circulating blood volume for hemorrhagic shock resuscitation, early use of cisapride for gastric motility is helpful for an improvement of lasting ischemia and hypoxia in stomach.

    Introduction It is known that thyroid homeostasis is altered during the acute phase of cardiac arrest. However, it is not clear under what conditions, how and for how long these alterations occur. In the present study we examined thyroid function tests (TFTs) in the acute phase of cardiac arrest caused by acute coronary syndrome (ACS) and at the end of the first 2 months after the event. Method Fifty patients with cardiac arrest induced by ACS and 31 patients with acute myocardial infarction (AMI) who did not require cardioversion or cardiopulmonary resuscitation were enrolled in the study, as were 40 healthy volunteers. The patients were divided into three groups based on duration of cardiac arrest (10 min). Blood samples were collected for thyroid-stimulating hormone (TSH), tri-iodothyronine (T3), free T3, thyroxine (T4), free T4, troponin-I and creatine kinase-MB measurements. The blood samples for TFTs were taken at 72 hours and at 2 months after the acute event in the cardiac arrest and AMI groups, but only once in the control group. Results The T3 and free T3 levels at 72 hours in the cardiac arrest group were significantly lower than in both the AMI and control groups (P 0.05). At the 2-month evaluation, a dramatic improvement was observed in T3 and free T3 levels in the cardiac arrest group (P < 0.0001). In those patients whose cardiac arrest duration was in excess of 10 min, levels of T3, free T3, T4 and TSH were significantly lower than those in patients whose cardiac arrest duration was under 5 min (P < 0.001, P < 0.001, P < 0.005 and P < 0.05, respectively). Conclusion TFTs are significantly altered in cardiac arrest induced by ACS. Changes in TFTs are even more pronounced in patients with longer periods of resuscitation. The changes in the surviving patients were characterized by euthyroid sick syndrome, and this improved by 2 months in those patients who did not progress into a vegetative state. PMID:16137355

    Full Text Available JUSTIFICATIVA E OBJETIVOS: As novas diretrizes contêm modificações significativas para tentar melhorar a prática da reanimação e a sobrevida de pacientes com parada cardíaca. Este artigo teve por objetivo revisar as principais alterações na reanimação praticada pelo profissional de saúde. CONTEÚDO: São várias as novas recomendações quanto à reanimação cardiopulmonar (RCP, a maioria com a finalidade de prover boa circulação durante a parada cardíaca. A alteração mais importante é a ênfase na qualidade das compressões torácicas. A relação universal de 30:2 é recomendada para simplificar o treinamento, alcançar ótima freqüência delas e reduzir as interrupções. Choque único é aplicado quando indicado, seguido imediatamente de RCP. Este choque deve ser de 120 a 200J, quando onda bifásica ou 360J quando onda monofásica. Os socorristas nunca devem interromper as compressões torácicas para verificar o ritmo antes de terminar os 5 ciclos, ou aproximadamente 2 minutos de RCP. Após este período, se um ritmo organizado estiver presente, o profissional de saúde deve observar o pulso. Existem várias e pequenas alterações quanto aos fármacos administrados durante a RCP de acordo com o ritmo. Dada a falta de evidência de qualquer destes fármacos melhorar a sobrevida em longo prazo durante a parada cardíaca, a seqüência de RCP enfatiza muito mais o suporte básico de vida. CONCLUSÕES: É importante a atualização quanto às novas diretrizes de RCP para melhorar a qualidade da reanimação e alcançar melhores taxas de sobrevida dos pacientes críticos.BACKGROUND AND OBJECTIVES: New resuscitation guidelines contain significant changes intended to improve resuscitation practice and survival from cardiac arrest.

    Full Text Available Abstract Background Training of lay first responder personnel situated closer to the potential victims than medical professionals is a strategy potentially capable of shortening the interval between collapse and start of cardiopulmonary resuscitation (CPR in cases of out-of-hospital cardiac arrest. In this study we trained lay first responders personnel in basic life support (BLS and defibrillation for cases of cardiac arrest and suspected acute myocardial infarction (AMI. Methods Forty-two lay first responders living in remote areas or working in industries in the island community of Austevoll, Western Norway, were trained in CPR and defibrillation. We placed particular emphasis on the first responders being able to defibrillate a primary ventricular fibrillation (PVF in patients with AMI. The trainees were organised in four teams to attend victims of AMI and cardiac arrest while awaiting the arrival of the community emergency medical services. The purpose of the study was to find out whether the teams were able to function during the five-year study project, and to examine whether lives could be saved. The first responders completed questionnaires each year on their experiences of participation. Data on the medical actions of the teams were also collected. Results By the end of the project all groups were functioning. The questionnaires evidenced a reasonable degree of motivation and self-evaluated competence in both types of group organisation, but in spite of this attrition effects in the first responders were considerable. The first responders were called out on 24 occasions, for a total of 17 patients. During the study period no case of PVF occurred after the arrival of the first responders, and the number of AMIs was very low, strongly deviating from what was anticipated. No lives were saved by the project. Conclusions The teams were sustained for almost five years without any significant deterioration of self-reported stress or mastering

  20. Stimulating endogenous cardiac regeneration

    2015-09-01

    Full Text Available The healthy adult heart has a low turnover of cardiac myocytes. The renewal capacity, however, is augmented after cardiac injury. Participants in cardiac regeneration include cardiac myocytes themselves, cardiac progenitor cells, and peripheral stem cells, particularly from the bone marrow compartment. Cardiac progenitor cells and bone marrow stem cells are augmented after cardiac injury, migrate to the myocardium, and support regeneration. Depletion studies of these populations have demonstrated their necessary role in cardiac repair. However, the potential of these cells to completely regenerate the heart is limited. Efforts are now being focused on ways to augment these natural pathways to improve cardiac healing, primarily after ischemic injury but in other cardiac pathologies as well. Cell and gene therapy or pharmacological interventions are proposed mechanisms. Cell therapy has demonstrated modest results and has passed into clinical trials. However, the beneficial effects of cell therapy have primarily been their ability to produce paracrine effects on the cardiac tissue and recruit endogenous stem cell populations as opposed to direct cardiac regeneration. Gene therapy efforts have focused on prolonging or reactivating natural signaling pathways. Positive results have been demonstrated to activate the endogenous stem cell populations and are currently being tested in clinical trials. A potential new avenue may be to refine pharmacological treatments that are currently in place in the clinic. Evidence is mounting that drugs such as statins or beta blockers may alter endogenous stem cell activity. Understanding the effects of these drugs on stem cell repair while keeping in mind their primary function may strike a balance in myocardial healing. To maximize endogenous cardiac regeneration,a combination of these approaches couldameliorate the overall repair process to incorporate the participation ofmultiple cell players.

  4. Opiate Withdrawal Complicated by Tetany and Cardiac Arrest

    2014-01-01

    Full Text Available Patients with symptoms of opiate withdrawal, after the administration of opiate antagonist by paramedics, are a common presentation in the emergency department of hospitals. Though most of opiate withdrawal symptoms are benign, rarely they can become life threatening. This case highlights how a benign opiate withdrawal symptom of hyperventilation led to severe respiratory alkalosis that degenerated into tetany and cardiac arrest. Though this patient was successfully resuscitated, it is imperative that severe withdrawal symptoms are timely identified and immediate steps are taken to prevent catastrophes. An easier way to reverse the severe opiate withdrawal symptom would be with either low dose methadone or partial opiate agonists like buprenorphine. However, if severe acid-base disorder is identified, it would be safer to electively intubate these patients for better control of their respiratory and acid-base status.

    Restrictive cardiomyopathy (RCM) is a specific group of heart muscle disorders characterized by inadequate ventricular relaxation during diastole. This leads to diastolic dysfunction with relative preservation of systolic function. Although short axis systolic function is usually preserved in RCM, the long axis systolic function may be severely impaired. Confirmation of diagnosis and information regarding aetiology, extent of myocardial damage, and response to treatment requires imaging. Importantly, differentiation from constrictive pericarditis (CCP) is needed, as only the latter is managed surgically. Echocardiography is the initial cardiac imaging technique but cannot reliably suggest a tissue diagnosis; although recent advances, especially tissue Doppler imaging and spectral tracking, have improved its ability to differentiate RCM from CCP. Cardiac catheterization is the reference standard, but is invasive, two-dimensional, and does not aid myocardial characterization. Cardiac magnetic resonance (CMR) is a versatile technique providing anatomical, morphological and functional information. In recent years, it has been shown to provide important information regarding disease mechanisms, and also been found useful to guide treatment, assess its outcome and predict patient prognosis. This review describes the CMR features of RCM, appearances in various diseases, its overall role in patient management, and how it compares with other imaging techniques.

    Gastrointestinal (GI) complications are an uncommon but potentially devastating complication of cardiac surgery. The reported incidence varies between .3% and 5.5% with an associated mortality of .3-87%. A wide range of GI complications are reported with bleeding, mesenteric ischemia, pancreatitis, cholecystitis, and ileus the most common. Ischemia is thought to be the main cause of GI complications with hypoperfusion during cardiac surgery as well as systemic inflammation, hypothermia, drug therapy, and mechanical factors contributing. Several nonischemic mechanisms may contribute to GI complications, including bacterial translocation, adverse drug reactions, and iatrogenic organ injury. Risk factors for GI complications are advanced age (>70 years), reoperation or emergency surgery, comorbidities (renal disease, respiratory disease, peripheral vascular disease, diabetes mellitus, cardiac failure), perioperative use of an intra-aortic balloon pump or inotrope therapy, prolonged surgery or cardiopulmonary bypass, and postoperative complications. Multiple strategies to reduce the incidence of GI complications exist, including risk stratification scores, targeted inotrope and fluid therapy, drug therapies, and modification of cardiopulmonary bypass. Currently, no single therapy has consistently proven efficacy in reducing GI complications. Timely diagnosis and treatment, while tailored to the specific complication and patient, is essential for optimal management and outcomes in this challenging patient population. PMID:25208431

    Full Text Available Abstract Background To assess, whether arterial blood gas measurements during trauma patient's pre-hospital shock resuscitation yield useful information on haemodynamic response to fluid resuscitation by comparing haemodynamic and blood gas variables in patients undergoing two different fluid resuscitation regimens. Methods In a prospective randomised study of 37 trauma patients at risk for severe hypovolaemia, arterial blood gas values were analyzed at the accident site and on admission to hospital. Patients were randomised to receive either conventional fluid therapy or 300 ml of hypertonic saline. The groups were compared for demographic, injury severity, physiological and outcome variables. Results 37 patients were included. Mean (SD Revised Trauma Score (RTS was 7.3427 (0.98 and Injury Severity Score (ISS 15.1 (11.7. Seventeen (46% patients received hypertonic fluid resuscitation and 20 (54% received conventional fluid therapy, with no significant differences between the groups concerning demographic data or outcome. Base excess (BE values decreased significantly more within the hypertonic saline (HS group compared to the conventional fluid therapy group (mean BE difference -2.1 mmol/l vs. -0.5 mmol/l, p = 0.003. The pH values on admission were significantly lower within the HS group (mean 7.31 vs. 7.40, p = 0.000. Haemoglobin levels were in both groups lower on admission compared with accident site. Lactate levels on admission did not differ significantly between the groups. Conclusion Pre-hospital use of small-volume resuscitation led to significantly greater decrease of BE and pH values. A portable blood gas analyzer was found to be a useful tool in pre-hospital monitoring for trauma resuscitation.

    Full Text Available Objective To observe the effects of four cardiopulmonary resuscitation (CPR methods on lung ventilation of pigs with respiratory arrest. The four CPR methods included chest compression CPR (C-CPR, compression under the diaphragm CPR (D-CPR, abdominal compression CPR (A-CPR, and abdominal wall lifting and compression CPR (L-CPR. Methods  A total of 28 healthy domestic pigs were randomly divided into four groups. The pig respiratory arrest model was reproduced by intravenous injection of suxamethonium. Instantly after respiratory arrest, one of the 4 CPR methods was performed immediately on the groups of pigs respectively. After 2min of CPR, compression was stopped. The experimental pigs were given assisted respiration using a ventilator until autonomous respiration recovered. The tidal volume (VT in basic status and that during resuscitation by the four respective resuscitation methods was determined, and minute ventilation (MV was calculated. Furthermore, heart rate (HR, mean arterial blood pressure, and recovery time of autonomous respiration were compared between all the groups. Results In basic status, there was no statistical difference (P > 0.05 in VT and MV between the four groups. Approximately 2min after resuscitation, the VT and MV of D-CPR were higher than that of C-CPR; that of A-CPR was higher than that of D-CPR; and that of L-CPR was higher than that of A-CPR. The differences were statistically significant (P 0.05. HR in C-CPR and D-CPR were notably lower than the basic value (P < 0.01. Two minutes after resuscitation, mechanical ventilation was given, and HR in all the groups was close to the basic value 5 min after resuscitation. In the respiratory arrest pig model, L-CPR could provide more effective VT and MV than the other methods. Conclusion For the porcine respiratory arrest model, L-CPR can provide more effective lung ventilation than the other methods.

    Full Text Available Background. During resuscitation of cardiac arrest victims a variety of information in electronic format is recorded as part of the documentation of the patient care contact and in order to be provided for case review for quality improvement. Such review requires considerable effort and resources. There is also the problem of interobserver effects. Objective. We show that it is possible to efficiently analyze resuscitation episodes automatically using a minimal set of the available information. Methods and Results. A minimal set of variables is defined which describe therapeutic events (compression sequences and defibrillations and corresponding patient response events (annotated rhythm transitions. From this a state sequence representation of the resuscitation episode is constructed and an algorithm is developed for reasoning with this representation and extract review variables automatically. As a case study, the method is applied to the data abstraction process used in the King County EMS. The automatically generated variables are compared to the original ones with accuracies ≥90% for 18 variables and ≥85% for the remaining four variables. Conclusions. It is possible to use the information present in the CPR process data recorded by the AED along with rhythm and chest compression annotations to automate the episode review.

    50 000 deaths every year in France following heart problems. You or someone close to you, a friend, a relative, a colleague at work. You all probably know someone who has had a heart attack. Noting that 80% of all deaths occur outside hospital, the Fédération Française de Cardiologie, working in collaboration with first aid groups (rescue associations, etc.), are launching a nationwide campaign to train as many people as possible in what to do for cardiac first aid. According to specialists, more than half of all heart attack victims could have survived if someone nearby had been quick at doing what was needed. The CERN Fire Brigade is helping in this campaign by offering two free training sessions, each lasting three hours and mainly based on recognizing a heart attack, the proper way of calling for help, and practice in mouth-to-mouth resuscitation and heart massage. The courses will be held on 20 November and 6 December from4 to 7 p.m. at Building 65. So don’t wait, stop b...

    Approximately 100 million people undergo noncardiac surgery annually worldwide. It is estimated that around 3% of patients undergoing noncardiac surgery experience a major adverse cardiac event. Although cardiac events, like myocardial infarction, are major cause of perioperative morbidity or mortality, its true incidence is difficult to assess. The risk of perioperative cardiac complications depends mainly on two conditions: 1) identified risk factors, and 2) the type of the surgical p...

    International guidelines for cardiopulmonary resuscitation recommend mild hypothermia (32-34 degrees C) for 12-24h in comatose survivors of cardiac arrest. To induce therapeutic hypothermia a variety of external and intravascular cooling devices are available. A cheap and effective method for inducing hypothermia is the infusion of large volume, ice-cold intravenous fluid. There are concerns regarding the effects of rapid infusion of large volumes of fluid on respiratory function in cardiac arrest survivors. We have retrospectively studied the effects of high volume cold fluid infusion on respiratory function in 52 resuscitated cardiac arrest patients. The target temperature of 32-34 degrees C was achieved after 4.1+/-0.5h (cooling rate 0.48 degrees C/h). During this period 3427+/-210 mL ice-cold fluid was infused. Despite significantly reduced LV-function (EF 35.8+/-2.2%) the respiratory status of these patients did not deteriorate significantly. On intensive care unit admission the mean PaO(2) was 231.4+/-20.6 mmHg at a F(i)O(2) of 0.82+/-0.03 (PaO(2)/F(i)O(2)=290.0+/-24.1) and a PEEP level of 7.14+/-0.31 mbar. Until reaching the target temperature of fluid is an effective and inexpensive method for inducing therapeutic hypothermia. Resuscitation from cardiac arrest is associated with a deterioration in respiratory function. The infusion of large volumes of cold fluid does not cause a statistically significant further deterioration in respiratory function. A larger, randomized and prospective study is required to assess the efficacy and safety of ice-cold fluid infusion for the induction of therapeutic hypothermia. PMID:19674825

    The diagnosis and treatment of clinical electrophysiology has a long and fascinating history. From earliest times, no clinical symptom impressed the patient (and the physician) more than an irregular heart beat. Although ancient Chinese pulse theory laid the foundation for the study of arrhythmias and clinical electrophysiology in the 5th century BC, the most significant breakthrough in the identification and treatment of cardiac arrhythmias first occurred in this century. In the last decades, our knowledge of electrophysiology and pharmacology has increased exponentially. The enormous clinical significance of cardiac rhythm disturbances has favored these advances. On the one hand, patients live longer and thus are more likely to experience arrhythmias. On the other hand, circulatory problems of the cardiac vessels have increased enormously, and this has been identified as the primary cause of cardiac rhythm disorders. Coronary heart disease has become not just the most significant disease of all, based on the statistics for cause of death. Arrhythmias are the main complication of ischemic heart disease, and they have been directly linked to the frequently arrhythmogenic sudden death syndrome, which is now presumed to be an avoidable "electrical accident" of the heart. A retrospective look--often charming in its own right--may not only make it easier to sort through the copious details of this field and so become oriented in this universe of important and less important facts: it may also provide the observer with a chronological vantage point from which to view the subject. The study of clinical electrophysiology is no dry compendium of facts and figures, but rather a dynamic field of study evolving out of the competition between various ideas, intentions and theories.

    Objective To study the resuscitative effect of hypertonic electrolyte glucose solution (HEGS) in enteral resuscitation of burn shock. Methods Eighteen Beagle dogs with 35% TBSA full-thickness flame injury were used in this study. They were randomized to a control group (no-fluid resuscitation, N group), a HEGS resuscitation group (H group) or an isotonic electrolyte glucose solution (IEGS) resuscitation group (Ⅰ group). The solution enterally was given for resuscitation from half an hour after burn. The volumes and rates of fluid infusion in the H group were basically in accordance with 2 ml/ TBSA)]. The hacmedynarnie parameters, global end-diastolic volume index, plasma volume, osmotic pressure of plasma, intestinal absorptive rates of water and Na~+, and intestine mueosa blood flow were continuously assessed. Results The cardiac output index, global end-diastolic volume index, plasma volume and intestine blood mucosa flow reduced markedly after burn in the three groups, and then gradually returned from 2 h after burn in two resuscitation groups, which were higher than that in the N group (P 0.05);高渗液组补液后血浆渗透浓度明显升高,显著高于其他两组(P<0.05);烧伤后两补液组肠道对复苏液中的水分和钠离子的吸收速率均逐渐增加,高渗液组肠道对水分吸收速率低于等渗液组(P<0.05),钠离子吸收速率则高于等渗液组(P<0.05).结论 35%TBSA烧伤后0.5 h通过肠内补充HEGS可以被肠道有效吸收,并在减少1/2补液量的前提下,基本维持有效血容量,达到肠内补充等渗液体复苏相似的血流动力学效果.

    Full Text Available Background: High stakes medical licensing programs are planning to augment and adapt current examinations to be relevant for a two-decision point model for licensure: entry into supervised practice and entry into unsupervised practice. Therefore, identifying which skills should be assessed at each decision point is critical for informing examination development, and gathering input from residency program directors is important. Methods: Using data from previously developed surveys and expert panels, a web-delivered survey was distributed to 3,443 residency program directors. For each of the 28 procedural and 18 advanced communication skills, program directors were asked which clinical skills should be assessed, by whom, when, and how. Descriptive statistics were collected, and Intraclass Correlations (ICC were conducted to determine consistency across different specialties. Results: Among 347 respondents, program directors reported that all advanced communication and some procedural tasks are important to assess. The following procedures were considered ‘important’ or ‘extremely important’ to assess: sterile technique (93.8%, advanced cardiovascular life support (ACLS (91.1%, basic life support (BLS (90.0%, interpretation of electrocardiogram (89.4% and blood gas (88.7%. Program directors reported that most clinical skills should be assessed at the end of the first year of residency (or later and not before graduation from medical school. A minority were considered important to assess prior to the start of residency training: demonstration of respectfulness (64%, sterile technique (67.2%, BLS (68.9%, ACLS (65.9% and phlebotomy (63.5%. Discussion: Results from this study support that assessing procedural skills such as cardiac resuscitation, sterile technique, and phlebotomy would be amenable to assessment at the end of medical school, but most procedural and advanced communications skills would be amenable to assessment at the end of the

    This article proposes a counter-argument to standard Advanced Trauma Life Support (ATLS) training--which advocates bladder catheterisation to be performed as an adjunct to the primary survey and resuscitation for early decompression of the bladder and urine output monitoring. We argue the case for delaying bladder catheterisation until after definitive truncal Computed Tomography (CT) imaging. To reduce pelvic volume and associated bleeding, our trauma team delay catheter insertion until after the initial CT scan. The benefits of a full bladder also include improved views on initial Focussed Assessment with Sonography in Trauma (FAST) scan and improved interpretation of injuries on CT. Our urinary catheter related infection rates anecdotally decreased when insertion was delayed and consequently performed in a more controlled, non-resuscitation setting following CT. Adult blunt multitrauma patients with pelvic ring fractures are at risk of significant haemorrhage. Venous, arterial and medullary injuries with associated bleeding may be potentiated by an increased pelvic volume with ring disruption, as well as a reduced pressure effect from retroperitoneal and intra-pelvic organs on bleeding sites. Various techniques are used to reduce intra-pelvic bleeding. For shocked patients who have sustained major pelvic injuries with no other signs of urinary tract trauma and minimal urine in the bladder on initial FAST scan, we advocate careful, aseptic Foley catheter insertion followed by bladder insufflation with 500-600 mL of Normal Saline (NS) and subsequent catheter clamping to tamponade pelvic bleeding.
