Drowning is a major public health issue, with risk increasing during times of flood. Driving though floodwater is a major risk factor for flood-related drowning and injury, and despite widespread public health campaigns, many people continue to undertake this risky behaviour and require rescue. We aimed to identify key challenges faced by emergency services personnel when rescuing those who have driven into floodwater, and to identify strategies for supporting rescuers in this important role. Australian flood rescue operators (N=8) who had previously rescued a driver who had driven through floodwater, participated in semi-structured interviews. Data were analysed using thematic analysis. Four challenges emerged from their experiences: Involvement of untrained personnel, varying information provided by emergency telephone operators, behaviour of drivers complicating the rescue, people sightseeing floods or flood rescues, or ignoring closed roads providing sources of distraction and frustration. We propose five strategies for translating these results into practice, including: training and protocol development for (1) emergency personnel and (2) telephone operators, (3) training for rescuers regarding non-compliant rescuees, (4) educating the public, and (5) increasing compliance with closed roads. Current findings provide valuable insights into how rescuers can be supported in performing their roles, and implementation of these strategies has the potential to reduce fatalities occurring due to driving through floodwater. SO WHAT?: The strategies presented have the potential to reduce the frequency and improve the outcomes of floodwater rescues, aiding in the prevention of injury and death.

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.

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

The aim of this study was to evaluate whether socioemotional stress affects the quality of cardiopulmonary resuscitation during advanced life support in a simulated manikin model. A randomized crossover trial with advanced life support performed in two different conditions, with and without exposure to socioemotional stress. The study was conducted at the Stavanger Acute Medicine Foundation for Education and Research simulation center, Stavanger, Norway. Paramedic teams, each consisting of two paramedics and one assistant, employed at Stavanger University Hospital, Stavanger, Norway. A total of 19 paramedic teams performed advanced life support twice in a randomized fashion, one control condition without socioemotional stress and one experimental condition with exposure to socioemotional stress. The socioemotional stress consisted of an upset friend of the simulated patient who was a physician, spoke a foreign language, was unfamiliar with current Norwegian resuscitation guidelines, supplied irrelevant clinical information, and repeatedly made doubts about the paramedics' resuscitation efforts. Aural distractions were supplied by television and cell telephone. The primary outcome was the quality of cardiopulmonary resuscitation: chest compression depth, chest compression rate, time without chest compressions (no-flow ratio), and ventilation rate after endotracheal intubation. As a secondary outcome, the socioemotional stress impact was evaluated through the paramedics' subjective workload, frustration, and feeling of realism. There were no significant differences in chest compression depth (39 vs. 38 mm, p = .214), compression rate (113 vs. 116 min⁻¹, p = .065), no-flow ratio (0.15 vs. 0.15, p = .618), or ventilation rate (8.2 vs. 7.7 min⁻¹, p = .120) between the two conditions. There was a significant increase in the subjective workload, frustration, and feeling of realism when the paramedics were exposed to socioemotional stress. In this advanced life

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

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

Extracorporeal Cardiopulmonary Resuscitation (ECPR) has emerged as a feasible rescue therapy for refractory, normothermic out-of-hospital cardiac arrest (OHCA). Reported survival rates vary and comparison between studies is hampered by heterogeneous study populations, differences in bystander intervention and in pre-hospital emergency service organisation. We aimed to describe the first experiences, treatment details, complications and outcome with ECPR for OHCA in a Danish health region. Retrospective study of adult patients admitted at Aarhus University Hospital, Denmark between 1 January 2011 and 1 July 2015 with witnessed, refractory, normothermic OHCA treated with ECPR. OHCA was managed with pre-hospital advanced airway management and mechanical chest compression during transport. Relevant pre-hospital and in-hospital data were collected with special focus on low-flow time and ECPR duration. Survival to hospital discharge with Cerebral Performance Category (CPC) of 1 and 2 at hospital discharge was the primary endpoint. Twenty-one patients were included. Median pre-hospital low-flow time was 54 min [range 5-100] and median total low-flow time was 121 min [range 55-192]. Seven patients survived (33%). Survivors had a CPC score of 1 or 2 at hospital discharge. Five survivors had a shockable initial rhythm. In all survivors coronary occlusion was the presumed cause of cardiac arrest. Extracorporeal cardiopulmonary resuscitation is feasible as a rescue therapy in normothermic refractory OHCA in highly selected patients. Low-flow time was longer than previously reported. Survival with favourable neurological outcome is possible despite prolonged low-flow duration. © 2016 The Acta Anaesthesiologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

The objective of this study is to investigate reliability and accuracy of the information on YouTube videos related to CPR and BLS in accord with 2010 CPR guidelines. YouTube was queried using four search terms 'CPR', 'cardiopulmonary resuscitation', 'BLS' and 'basic life support' between 2011 and 2013. Sources that uploaded the videos, the record time, the number of viewers in the study period, inclusion of human or manikins were recorded. The videos were rated if they displayed the correct order of resuscitative efforts in full accord with 2010 CPR guidelines or not. Two hundred and nine videos meeting the inclusion criteria after the search in YouTube with four search terms ('CPR', 'cardiopulmonary resuscitation', 'BLS' and 'basic life support') comprised the study sample subjected to the analysis. Median score of the videos is 5 (IQR: 3.5-6). Only 11.5% (n = 24) of the videos were found to be compatible with 2010 CPR guidelines with regard to sequence of interventions. Videos uploaded by 'Guideline bodies' had significantly higher rates of download when compared with the videos uploaded by other sources. Sources of the videos and date of upload (year) were not shown to have any significant effect on the scores received (P = 0.615 and 0.513, respectively). The videos' number of downloads did not differ according to the videos compatible with the guidelines (P = 0.832). The videos downloaded more than 10,000 times had a higher score than the others (P = 0.001). The majority of You-Tube video clips purporting to be about CPR are not relevant educational material. Of those that are focused on teaching CPR, only a small minority optimally meet the 2010 Resucitation Guidelines. © 2014 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

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

Validating participants' ability to correctly perform cardiopulmonary resuscitation (CPR) skills during basic life support courses can be a challenge for nursing professional development specialists. This study compares two methods of basic life support training, instructor-led and computer-based learning with voice-activated manikins, to identify if one method is more effective for performance of CPR skills. The findings suggest that a computer-based learning course with voice-activated manikins is a more effective method of training for improved CPR performance.

Full Text Available Cardiopulmonary bypass (CPB provides a bloodless field for cardiac surgery. It incorporates an extracorporeal circuit to provide physiological support in which venous blood is drained to a reservoir, oxygenated and sent back to the body using a pump. Team effort between surgeon, perfusionist and anaesthesiologist is paramount for the successful use of CPB. However, it also has its share of complications and strategies to reduce these complications are the area of the current research.

Extracorporeal Cardiopulmonary Resuscitation Among Patients with Structurally Normal Hearts.

Conrad, Stephanie J; Bridges, Brian C; Kalra, Yuvraj; Pietsch, John B; Smith, Andrew H

Extracorporeal cardiopulmonary resuscitation (eCPR) has been well described as a rescue therapy in refractory cardiac arrest among patients with congenital heart disease. The purpose of this retrospective analysis of data from the Extracorporeal Life Support Organization was to evaluate outcomes of eCPR in patients with structurally normal hearts and to identify risk factors that may contribute to mortality. During the study period, 1,431 patients met inclusion criteria. Median age was 16 years. Overall survival to hospital discharge was 32%. Conditional logistic regression demonstrated an independent survival benefit among smaller patients, patients with a lower partial pressure of carbon dioxide (PaCO2) on cannulation, and those with a shorter duration from intubation to eCPR cannulation. A diagnosis of sepsis was independently associated with a nearly threefold increase in odds of mortality, whereas the diagnosis of myocarditis portended a more favorable outcome. Neurologic complications, pulmonary hemorrhage, disseminated intravascular coagulation, CPR, pH less than 7.20, and hyperbilirubinemia after eCPR cannulation were independently associated with an increase in odds of mortality. When utilizing eCPR in patients with structurally normal hearts, a diagnosis of sepsis is independently associated with mortality, whereas a diagnosis of myocarditis is protective. Neurologic complications and pulmonary hemorrhage while on extracorporeal membrane oxygenation (ECMO) are independently associated with mortality.

2016-01-01

This article develops and validates a new methodology and tool for rescue assistance in traffic accidents, with the aim of improving its efficiency and safety in the evacuation of people, reducing the number of victims in road accidents. Different tests supported by professionals and experts have been designed under different circumstances and with different categories of damaged vehicles coming from real accidents and simulated trapped victims in order to calibrate and refine the proposed methodology and tool. To validate this new approach, a tool called App_Rescue has been developed. This tool is based on the use of a computer system that allows an efficient access to the technical information of the vehicle and sanitary information of the common passengers. The time spent during rescue using the standard protocol and the proposed method was compared. This rescue assistance system allows us to make vital information accessible in posttrauma care services, improving the effectiveness of interventions by the emergency services, reducing the rescue time and therefore minimizing the consequences involved and the number of victims. This could often mean saving lives. In the different simulated rescue operations, the rescue time has been reduced an average of 14%.

To assess whether access to a voice activated decision support system (VADSS) containing video clips demonstrating resuscitation manoeuvres was associated with increased compliance with American Heart Association Basic Life Support (AHA BLS) guidelines. This was a prospective, randomised controlled trial. Subjects with no recent clinical experience were randomised to the VADSS or control group and participated in a 5-min simulated out-of-hospital cardiopulmonary arrest with another 'bystander'. Data on performance for predefined outcome measures based on the AHA BLS guidelines were abstracted from videos and the simulator log. 31 subjects were enrolled (VADSS 16 vs control 15), with no significant differences in baseline characteristics. Study subjects in the VADSS were more likely to direct the bystander to: (1) perform compressions to ventilations at the correct ratio of 30:2 (VADSS 15/16 (94%) vs control 4/15 (27%), p=compressor versus ventilator roles after 2 min (VADSS 12/16 (75%) vs control 2/15 (13%), p=0.001). The VADSS group took longer to initiate chest compressions than the control group: VADSS 159.5 (±53) s versus control 78.2 (±20) s, pcontrol 75.4 (±8.0), p=0.35. The use of an audio and video assisted decision support system during a simulated out-of-hospital cardiopulmonary arrest prompted lay rescuers to follow cardiopulmonary resuscitation (CPR) guidelines but was also associated with an unacceptable delay to starting chest compressions. Future studies should explore: (1) if video is synergistic to audio prompts, (2) how mobile technologies may be leveraged to spread CPR decision support and (3) usability testing to avoid unintended consequences.

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

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

Space Rescue

Muratore, John F.

2007-01-01

Space Rescue has been a topic of speculation for a wide community of people for decades. Astronauts, aerospace engineers, diplomats, medical and rescue professionals, inventors and science fiction writers have all speculated on this problem. Martin Caidin's 1964 novel Marooned dealt with the problems of rescuing a crew stranded in low earth orbit. Legend at the Johnson Space Center says that Caidin's portrayal of a Russian attempt to save the American crew played a pivotal role in convincing the Russians to join the real joint Apollo-Soyuz mission. Space Rescue has been a staple in science fiction television and movies portrayed in programs such as Star Trek, Stargate-SG1 and Space 1999 and movies such as Mission To Mars and Red Planet. As dramatic and as difficult as rescue appears in fictional accounts, in the real world it has even greater drama and greater difficulty. Space rescue is still in its infancy as a discipline and the purpose of this chapter is to describe the issues associated with space rescue and the work done so far in this field. For the purposes of this chapter, the term space rescue will refer to any system which allows for rescue or escape of personnel from situations which endanger human life in a spaceflight operation. This will span the period from crew ingress prior to flight through crew egress postlanding. For the purposes of this chapter, the term primary system will refer to the spacecraft system that a crew is either attempting to escape from or from which an attempt is being made to rescue the crew.

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

Fabry's disease is an X-linked lysosomal storage disease caused by deficiency of alpha-galactosidase A enzyme activity. Decreased enzyme activity leads to accumulation of glycosphingolipid in different tissues, including endothelial and smooth-muscle cells and cardiomyocytes. There is controversial data on cardiopulmonary involvement in Fabry's disease, because many reports are based on small and selected populations with Fabry's disease. Furthermore, the aetiology of cardiopulmonary symptoms in Fabry's disease is poorly understood. We studied cardiopulmonary involvement in seventeen patients with Fabry's disease (20-65 years, 6 men) using ECG, bicycle stress, cardiac magnetic resonance imaging, spirometry, diffusing capacity and pulmonary high-resolution computed tomography (HRCT) tests. Cardiopulmonary symptoms were compared to observed parameters in cardiopulmonary tests. Left ventricular hypertrophy (LVH) and reduced exercise capacity are the most apparent cardiac changes in both genders with Fabry's disease. ECG parameters were normal when excluding changes related to LVH. Spirometry showed mild reduction in vital capacity and forced expiratory volume in one second (FEV I), and mean values in diffusing capacity tests were within normal limits. Generally, only slight morphological pulmonary changes were detected using pulmonary HRCT, and they were not associated with changes in pulmonary function. The self-reported amount of pulmonary symptoms associated only with lower ejection fraction (P routine cardiopulmonary evaluation in Fabry's disease using echocardiography is maybe enough when integrated to counselling for aerobic exercise training.

The presentation is based in the research work carried out in EU funded project SGL for USaR (Second Generation Locator for Urban Search and Rescue Operations). The aim of this project is to develop wireless standalone communication system with embedded sensor network which can be globally used in rescue operations after accidents or terrorist attacks. The system should be able to operate without external support for several days: it should have autonomy with power supply and communication. The devices must be lightweight so that rescue team can easily carry them and finally they must be easy to install and use. The range of the wireless communication must cover an area of several square kilometers. The embedded sensor system must be able to detect sings of life but also detect hazards threatening the rescue operators thus preventing more accidents. It should also support positioning and digital mapping as well as the management of the search and rescue operation. This sensor network for urban search and rescue operations has been tested on a field conditions and it has proven to be robust and reliable and provides an energy efficient way of communication and positioning on harsh conditions.

Emergent cardiopulmonary bypass during pectus excavatum repair

Directory of Open Access Journals (Sweden)

Ryan Craner

2013-01-01

Full Text Available Pectus excavatum is a chest wall deformity that produces significant cardiopulmonary disability and is typically seen in younger patients. Minimally invasive repair of pectus excavatum or Nuss procedure has become a widely accepted technique for adult and pediatric patients. Although it is carried out through a thoracoscopic approach, the procedure is associated with a number of potential intraoperative and post-operative complications. We present a case of cardiac perforation requiring emergent cardiopulmonary bypass in a 29-year-old male with Marfan syndrome and previous mitral valve repair undergoing a Nuss procedure for pectus excavatum. This case illustrates the importance of vigilance and preparation by the surgeons, anesthesia providers as well as the institution to be prepared with resources to handle the possible complications. This includes available cardiac surgical backup, perfusionist support and adequate blood product availability.

Is increased positive end-expiratory pressure the culprit? Autoresuscitation in a 44-year-old man after prolonged cardiopulmonary resuscitation: a case report.

The phenomenon of autoresuscitation is rare, yet it is known to most emergency physicians. However, the pathophysiology of the delayed return of spontaneous circulation remains enigmatic. Among other causes hyperinflation of the lungs and excessively high positive end-expiratory pressure have been suggested, but reports including cardiopulmonary monitoring during cardiopulmonary resuscitation are scarce to support this hypothesis. We report a case of autoresuscitation in a 44-year-old white man after 80 minutes of advanced cardiac life support accompanied by continuous capnometry and repeated evaluation by ultrasound and echocardiography. After prolonged cardiopulmonary resuscitation, refractory electromechanical dissociation on electrocardiogram and ventricular akinesis were recorded. In addition, a precipitous drop in end-tidal partial pressure of carbon dioxide was noted and cardiopulmonary resuscitation was discontinued. Five minutes after withdrawal of all supportive measures his breathing resumed and a perfusing rhythm ensued. Understanding the underlying pathophysiology of autoresuscitation is hampered by a lack of reports including extensive cardiopulmonary monitoring during cardiopulmonary resuscitation in a preclinical setting. In this case, continuous capnometry was combined with repetitive ultrasound evaluation, which ruled out most assumed causes of autoresuscitation. Our observation of a rapid decline in end-tidal partial pressure of carbon dioxide supports the hypothesis of increased intrathoracic pressure. Continuous capnometry can be performed easily during cardiopulmonary resuscitation, also in a preclinical setting. Knowledge of the pathophysiologic mechanisms may lead to facile interventions to be incorporated into cardiopulmonary resuscitation algorithms. A drop in end-tidal partial pressure of carbon dioxide, for example, might prompt disconnection of the ventilation to allow left ventricular filling. Further reports and research on this topic

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

Full Text Available Objective: To analyze the protective effect of dexmedetomidine combined with ulinastatin on cardiopulmonary function impairment caused by cardiopulmonary bypass surgery. Methods: A total of 78 patients who received valve replacement under cardiopulmonary bypass were divided into observation group and control group (n=39 according to random number table. Control group received intraoperative ulinastatin intervention and observation group received intraoperative dexmedetomidine combined with ulinastatin intervention. Differences in the levels of cardiac function indexes, myocardial injury markers, pulmonary function parameters, inflammatory indexes and so on were compared between two groups of patients 24 hours after operation. Results: Cardiac function parameters LSV, RSV and RVEF values of observation group 24 hours after operation were higher than those of control group while PAP value was lower than that of control group; serum myocardial injury markers H-FABP, cTn-T, CKMB, cTnⅠ and NT-proBNP levels were lower than those of control group; lung function parameters Cs and Cd values were higher than those of control group while RI, R5-R20, X5 and Fres values were lower than those of control group; serum pro-inflammatory factors IL-6 and TNF-α levels were lower than those of control group while anti-inflammatory factors sTNF-RI, IL-4 and IL-10 levels were higher than those of control group. Conclusions: Dexmedetomidine combined with ulinastatin can protect the cardiopulmonary function in patients with cardiopulmonary bypass, and help to reduce the occurrence of postoperative cardiopulmonary dysfunction and other severe complications.

Health needs of different employee subgroups within an industry can differ. We report the results of a workplace cardiopulmonary risk assessment targeting workers and support staff in the construction industry. A free worksite-based cardiopulmonary risk assessment for 1,903 workers on infrastructural contracts across Hong Kong was initiated in May 2014. Cardiopulmonary risk screening was performed in 60-minute blocks for approximately 30 workers/block with individualized feedback and lifestyle counseling. Risk profiles stratified by occupational roles are differentiated using the χ2-test for categorical and Student's t-test for continuous variables. Most construction workers and clerks/professionals were male (83.2% and 71.2%, respectively) and Chinese (78.7% and 90.9%, respectively). Construction workers were older (mean: 44.9 years, SD 11.5) and less well-educated (6.1% received tertiary education) than clerks/professionals (35.0 years, 10.7; 72.6% received tertiary education), but more likely to be hypertensive (22.6% vs. 15.4%, pscreening can identify potentially high-cardiopulmonary-risk construction industry employee subgroups for onward confirmatory referral. Separate cardiopulmonary health promotion strategies that account for the varying lifestyle profiles of the two employee subgroups in the industry appear justified.

The process male nurse is a systematic and organized method to offer effective and efficient cares guided to the achievement of solving real problems of health, reducing the incidence and the duration. It is organized and systematic for that consists of five sequential and interrelated steps: Valuation, diagnostic, planning, execution and evaluation, in which are carried out interrelated actions, thought to maximize the long term results. The nurse process is based on the notion that the success of the cares is measured by the degree of effectiveness and the degree of satisfaction and the patient's progress. Applying this method in the Advanced Cardiac Live Support (ACLS) the identification of a cardiovascular or cardiopulmonary urgency was achieved that implies advanced treatment of the air road, defibrillation and appropriate medications to the circumstances. The ACLS challenges the nurses in charge from the patient's attention to make decisions quick low pressure and in dramatic scenes. Reason why it develops the flowing process male nurse in the advanced cardiopulmonary reanimation due to the incidence of these events in the National Institute of Cardiology Ignacio Chávez, which should guarantee the benefit of services in basic and advanced cardiopulmonary reanimation for personal with a high formation level in all the units of intensive cares and services of hospitalization in integrated form and stratified this way to avoid that it progresses to situations that cause the death or leave irreversible sequels since in the central nervous system the time it is a factor critical for the treatment of this events.

Descriptive and exploratory study, aimed to develop an educational practice of Problem-Based Learning in CPR/BLS with 24 students in the third stage of the Nursing Undergraduate Course in a University in the Southern region of Brazil. The study used the PBL methodology, focused on problem situations of cardiopulmonary arrest, and was approved by the CONEP. The methodological strategies for data collection, such as participative observation and questionnaires to evaluate the learning, the educational practices and their methodology, allowed for grouping the results in: students' expectations; group activities; individual activities; practical activities; evaluation of the meetings and their methodology. The study showed that PBL allows the educator to evaluate the academic learning process in several dimensions, functioning as a motivating factor for both the educator and the student, because it allows the theoretical-practical integration in an integrated learning process.

Food insecurity affects 13.4% of the USA population, despite the fact that 30-40% of all food is deposited in a landfill. Food rescue nutrition is the process of redistribution of surplus food to the impoverished. The aim of this study is to document the extent of involvement of organizations in food rescue nutrition. In this cross-sectional study, a survey about organizations involved in food rescue nutrition was developed, validated, and then tested. Directors of 100 organizations involved in food rescue nutrition from eight Southwestern States in the USA participated in this research. These organizations provided an average of 2 million kg of food to more than 40,000 clients each month. Food assistance programs had an average of eight workers and 3081 volunteers. In addition to food, these organizations provided other services such as clothing, clinical, and childcare. The agencies encountered several challenges, including lack of resources that resulted in reducing food portions and turning away clients. The extent of involvement of community-based programs in food rescue nutrition was strong in eight Southwestern states in the USA. Organizations involved in food redistribution helped alleviate food insecurity in their clients. Sustainability of these charitable networks was dependent on availability of resources and sufficient volunteers. Health professionals should encourage these organizations by providing support through donations of time, money, and/or food. Copyright © 2017 The Royal Society for Public Health.

No systematic evaluation of smartphone/mobile apps for resuscitation training and real incident support is available to date. To provide medical, usability, and additional quality criteria for the development of apps, we conducted a mixed-methods sequential evaluation combining the perspective of medical experts and end-users. The study aims to assess the quality of current mobile apps for cardiopulmonary resuscitation (CPR) training and real incident support from expert as well as end-user perspective. Two independent medical experts evaluated the medical content of CPR apps from the Google Play store and the Apple App store. The evaluation was based on pre-defined minimum medical content requirements according to current Basic Life Support (BLS) guidelines. In a second phase, non-medical end-users tested usability and appeal of the apps that had at least met the minimum requirements. Usability was assessed with the System Usability Scale (SUS); appeal was measured with the self-developed ReactionDeck toolkit. Out of 61 apps, 46 were included in the experts' evaluation. A consolidated list of 13 apps resulted for the following layperson evaluation. The interrater reliability was substantial (kappa=.61). Layperson end-users (n=14) had a high interrater reliability (intraclass correlation 1 [ICC1]=.83, Ptraining and real incident support are available, very few are designed according to current BLS guidelines and offer an acceptable level of usability and hedonic quality for laypersons. The results of this study are intended to optimize the development of CPR mobile apps. The app ranking supports the informed selection of mobile apps for training situations and CPR campaigns as well as for real incident support.

Cardiopulmonary resuscitation in palliative care cancer patients.

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

Research has shown that increased breathing frequency during cardiopulmonary resuscitation is inversely correlated with systolic blood pressure. Rescuers often hyperventilate during cardiopulmonary resuscitation (CPR). Current American Heart Association advanced cardiac life support recommends a ventilation rate of 8-10 breaths/min. We hypothesized that a small, turbine-driven ventilator would allow rescuers to adhere more closely to advanced cardiac life support (ACLS) guidelines. Twenty-four ACLS-certified health-care professionals were paired into groups of 2. Each team performed 4 randomized rounds of 2-min cycles of CPR on an intubated mannikin, with individuals altering between compressions and breaths. Two rounds of CPR were performed with a self-inflating bag, and 2 rounds were with the ventilator. The ventilator was set to deliver 8 breaths/min, pressure limit 22 cm H 2 O. Frequency, tidal volume (V T ), peak inspiratory pressure, and compression interruptions (hands-off time) were recorded. Data were analyzed with a linear mixed model and Welch 2-sample t test. The median (interquartile range [IQR]) frequency with the ventilator was 7.98 (7.98-7.99) breaths/min. Median (IQR) frequency with the self-inflating bag was 9.5 (8.2-10.7) breaths/min. Median (IQR) ventilator V T was 0.5 (0.5-0.5) L. Median (IQR) self-inflating bag V T was 0.6 (0.5-0.7) L. Median (IQR) ventilator peak inspiratory pressure was 22 (22-22) cm H 2 O. Median (IQR) self-inflating bag peak inspiratory pressure was 30 (27-35) cm H 2 O. Mean ± SD hands-off times for ventilator and self-inflating bag were 5.25 ± 2.11 and 6.41 ± 1.45 s, respectively. When compared with a ventilator, volunteers ventilated with a self-inflating bag within ACLS guidelines. However, volunteers ventilated with increased variation, at higher V T levels, and at higher peak pressures with the self-inflating bag. Hands-off time was also significantly lower with the ventilator. (ClinicalTrials.gov registration NCT

Cardiopulmonary arrest during and proximate to hemodialysis is rare but highly fatal. Studies have examined peridialytic sudden cardiac event risk factors, but no study has considered associates of cardiopulmonary arrests (fatal and nonfatal events including cardiac and respiratory causes). This study was designed to elucidate patient and procedural factors associated with peridialytic cardiopulmonary arrest. Data for this case-control study were taken from the hemodialysis population at Fresenius Medical Care, North America. 924 in-center cardiopulmonary events (cases) and 75,538 controls were identified. Cases and controls were 1 : 5 matched on age, sex, race, and diabetes. Predictors of cardiopulmonary arrest were considered for logistic model inclusion. Missed treatments due to hospitalization, lower body mass, coronary artery disease, heart failure, lower albumin and hemoglobin, lower dialysate potassium, higher serum calcium, greater erythropoietin stimulating agent dose, and normalized protein catabolic rate (J-shaped) were associated with peridialytic cardiopulmonary arrest. Of these, lower albumin, hemoglobin, and body mass index; higher erythropoietin stimulating agent dose; and greater missed sessions had the strongest associations with outcome. Patient health markers and procedural factors are associated with peridialytic cardiopulmonary arrest. In addition to optimizing nutritional status, it may be prudent to limit exposure to low dialysate potassium (<2 K bath) and to use the lowest effective erythropoietin stimulating agent dose.

Extracorporeal cardiopulmonary resuscitation (ECPR) in children with cardiac arrest refractory to conventional cardiopulmonary resuscitation (CPR) has been reported with encouraging results. We sought to review outcomes of neonates with functional single ventricle (FSV) receiving post-cardiotomy ECPR. Forty-eight patients who required post-cardiotomy extracorporeal membrane oxygenation (ECMO) since the introduction of our ECPR protocol (January 2007-December 2009) were identified. Twenty-seven were neonates. Review of records and survival analysis were conducted. Of 27 neonates receiving post-cardiotomy ECMO 20 had FSV. Fourteen had ECPR. Ten underwent Norwood operation (NO) for hypoplastic left heart syndrome (HLHS). Four had FSV other than HLHS. Three underwent Damus-Kay-Stansel or modified NO with systemic-to-pulmonary shunt (SPS) and one SPS with anomalous pulmonary venous connection repair. Mean age and weight were 7.8 ± 2.9 days and 3.44 ± 1.78 kg, respectively. ECMO median duration was 6 days (interquartile range (IQR) 3-14). Survival to ECMO discontinuation was 79% (11 of 14 patients) and at hospital discharge was 57% (8 of 14 patients). The most common cause of death was multi-organ failure (four of six deaths). At last follow-up (median: 11 months (1-34)) 43% of patients were alive. CPR mean duration for patients with favorable versus unfavorable outcome was 38.6 ± 6.3 versus 42.1 ± 7.7 min (p = 0.12). Previously reported determinants for poorer prognosis in conventional non-rescue ECMO (such as pre-ECMO pH0.05). ECMO support in neonates with FSV requiring ECPR can result in favorable outcome in more than half of patients at hospital discharge. Aggressive strategy toward timely application of ECPR is justified. Expeditious ECPR deployment after proper patients' selection, refinement of CPR quality and use of adjunctive neuroprotective interventions, such as induced hypothermia, might further improve outcomes.

Drotrecogin Alpha (Activated in Two Patients with the Hantavirus Cardiopulmonary Syndrome

Directory of Open Access Journals (Sweden)

Robert C McDermid

2006-01-01

Full Text Available Hantavirus cardiopulmonary syndrome (HCPS is associated with rapid cardiopulmonary collapse from endothelial injury, resulting in massive capillary leak, shock and severe hypoxemic respiratory failure. To date, treatment remains supportive and includes mechanical ventilation, vasopressors and extracorporeal membrane oxygenation, with mortality approaching 50%. Two HCPS survivors initially given drotrecogin alpha (activated (DAA for presumed bacterial septic shock are described. Vasoactive medications were required for a maximum of 52 h, whereas creatinine levels and platelet counts normalized within seven to nine days. Given the similar presentations of HCPS and bacterial septic shock, empirical DAA therapy will likely be initiated before a definitive diagnosis of HCPS is made. Further observations of DAA in HCPS seem warranted.

Previous studies have suggested that the incidence of post-traumatic stress disorder in earthquake rescue workers is relatively high. Risk factors for this disorder include demographic characteristics, earthquake-related high-risk factors, risk factors in the rescue process, personality, social support and coping style. This study examined the current status of a unit of 1 040 rescue workers who participated in earthquake relief for the Wenchuan earthquake that occurred on May 12(th), 2008. Post-traumatic stress disorder was diagnosed primarily using the Clinician-Administered Post-traumatic Stress Disorder Scale during structured interviews. Univariate and multivariate statistical analyses were used to examine major risk factors that contributed to the incidence of post-traumatic stress disorder. Results revealed that the incidence of this disorder in the rescue group was 5.96%. The impact factors in univariate analysis included death of family members, contact with corpses or witnessing of the deceased or seriously injured, near-death experience, severe injury or mental trauma in the rescue process and working at the epicenter of the earthquake. Correlation analysis suggested that post-traumatic stress disorder was positively correlated with psychotic and neurotic personalities, negative coping and low social support. Impact factors in multivariate logistic regression analysis included near-death experience, severe injury or mental trauma, working in the epicenter of the rescue, neurotic personality, negative coping and low social support, among which low social support had the largest odds ratio of 20.42. Findings showed that the occurrence of post-traumatic stress disorder was the result of the interaction of multiple factors.

Previous studies have suggested that the incidence of post-traumatic stress disorder in earthquake rescue workers is relatively high. Risk factors for this disorder include demographic characteristics, earthquake-related high-risk factors, risk factors in the rescue process, personality, social support and coping style. This study examined the current status of a unit of 1 040 rescue workers who participated in earthquake relief for the Wenchuan earthquake that occurred on May 12th, 2008. Post-traumatic stress disorder was diagnosed primarily using the Clinician-Administered Post-traumatic Stress Disorder Scale during structured interviews. Univariate and multivariate statistical analyses were used to examine major risk factors that contributed to the incidence of post-traumatic stress disorder. Results revealed that the incidence of this disorder in the rescue group was 5.96%. The impact factors in univariate analysis included death of family members, contact with corpses or witnessing of the deceased or seriously injured, near-death experience, severe injury or mental trauma in the rescue process and working at the epicenter of the earthquake. Correlation analysis suggested that post-traumatic stress disorder was positively correlated with psychotic and neurotic personalities, negative coping and low social support. Impact factors in multivariate logistic regression analysis included near-death experience, severe injury or mental trauma, working in the epicenter of the rescue, neurotic personality, negative coping and low social support, among which low social support had the largest odds ratio of 20.42. Findings showed that the occurrence of post-traumatic stress disorder was the result of the interaction of multiple factors. PMID:25206499

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

Vasilis Sitras

2010-01-01

Full Text Available Cardiopulmonary collapse during labour is a catastrophic event caused by various medical, surgical and obstetrical conditions. It is an emergency that threatens the life of the mother and her unborn child. We present a case of a pregnant woman who suffered from preeclampsia and underwent induction of labour. Severe lung edema occurred early in labour that caused cardiopulmonary collapse. Advanced heart-lung resuscitation was established immediately and continued until an emergency cesarean section was performed few minutes later. The outcome was favourable for both mother and child. We further discuss some aspects of the pathophysiology and appropriate treatment of cardiorespiratory arrest during labour, which involves the coordinated action of the obstetric, pediatric and surgical ward personnel.

Full Text Available AbstractObjective:To provide a brief review of the development of cardiopulmonary bypass.Methods:A review of the literature on the development of extracorporeal circulation techniques, their essential role in cardiovascular surgery, and the complications associated with their use, including hemolysis and inflammation.Results:The advancement of extracorporeal circulation techniques has played an essential role in minimizing the complications of cardiopulmonary bypass, which can range from various degrees of tissue injury to multiple organ dysfunction syndrome. Investigators have long researched the ways in which cardiopulmonary bypass may insult the human body. Potential solutions arose and laid the groundwork for development of safer postoperative care strategies.Conclusion:Steady progress has been made in cardiopulmonary bypass in the decades since it was first conceived of by Gibbon. Despite the constant evolution of cardiopulmonary bypass techniques and attempts to minimize their complications, it is still essential that clinicians respect the particularities of each patient's physiological function.

Emboli in the brain microvasculature may inhibit brain activity during cardiopulmonary bypass. Such hypothetical blockade, if confirmed, may be responsible for the reduction of cerebral metabolic rate for glucose observed in animals subjected to cardiopulmonary bypass. In previous studies of cerebral blood flow during bypass, brain microcirculation was not evaluated. In the present study in animals (pigs), reduction of the number of perfused capillaries was estimated by measurements of the capillary diffusion capacity for hydrophilic tracers of low permeability. Capillary diffusion capacity, cerebral blood flow, and cerebral metabolic rate for glucose were measured simultaneously by the integral method, different tracers being used with different circulation times. In eight animals subjected to normothermic cardiopulmonary bypass, and seven subjected to hypothermic bypass, cerebral blood flow, cerebral metabolic rate for glucose, and capillary diffusion capacity decreased significantly: cerebral blood flow from 63 to 43 ml/100 gm/min in normothermia and to 34 ml/100 gm/min in hypothermia and cerebral metabolic rate for glucose from 43.0 to 23.0 mumol/100 gm/min in normothermia and to 14.1 mumol/100 gm/min in hypothermia. The capillary diffusion capacity declined markedly from 0.15 to 0.03 ml/100 gm/min in normothermia but only to 0.08 ml/100 gm/min in hypothermia. We conclude that the decrease of cerebral metabolic rate for glucose during normothermic cardiopulmonary bypass is caused by interruption of blood flow through a part of the capillary bed, possibly by microemboli, and that cerebral blood flow is an inadequate indicator of capillary blood flow. Further studies must clarify why normal microvascular function appears to be preserved during hypothermic cardiopulmonary bypass

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

To explore the current literature on the failure to rescue and rescue surgery concepts, to identify the key items for decreasing the failure to rescue rate and improve outcome, to verify if there is a rationale for centralization of patients suffering postoperative complications. There is a growing awareness about the need to assess and measure the failure to rescue rate, on institutional, regional and national basis. Many factors affect failure to rescue, and all should be individually analyzed and considered. Rescue surgery is one of these factors. Rescue surgery assumes an acute care surgery background. Measurement of failure to rescue rate should become a standard for quality improvement programs. Implementation of all clinical and organizational items involved is the key for better outcomes. Preparedness for rescue surgery is a main pillar in this process. Centralization of management, audit, and communication are important as much as patient centralization. Celsius.

A SOUND SOURCE LOCALIZATION TECHNIQUE TO SUPPORT SEARCH AND RESCUE IN LOUD NOISE ENVIRONMENTS

Science.gov (United States)

Yoshinaga, Hiroshi; Mizutani, Koichi; Wakatsuki, Naoto

At some sites of earthquakes and other disasters, rescuers search for people buried under rubble by listening for the sounds which they make. Thus developing a technique to localize sound sources amidst loud noise will support such search and rescue operations. In this paper, we discuss an experiment performed to test an array signal processing technique which searches for unperceivable sound in loud noise environments. Two speakers simultaneously played a noise of a generator and a voice decreased by 20 dB (= 1/100 of power) from the generator noise at an outdoor space where cicadas were making noise. The sound signal was received by a horizontally set linear microphone array 1.05 m in length and consisting of 15 microphones. The direction and the distance of the voice were computed and the sound of the voice was extracted and played back as an audible sound by array signal processing.

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

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

Conventional hemofiltration during cardiopulmonary bypass increases the serum lactate level in adult cardiac surgery

Directory of Open Access Journals (Sweden)

Rabie Soliman

2016-01-01

Full Text Available Objective: To evaluate the effect of hemofiltration during cardiopulmonary bypass on lactate level in adult patients who underwent cardiac surgery. Design: An observational study. Setting: Prince Sultan cardiac center, Riyadh, Saudi Arabia. Participants: The study included 283 patients classified into two groups: Hemofiltration group (n=138, hemofiltration was done during CPB. Control group (n = 145, patients without hemofiltration. Interventions: Hemofiltration during cardiopulmonary bypass. Measurements and Main Results: Monitors included hematocrit, lactate levels, mixed venous oxygen saturation, amount of fluid removal during hemofiltration and urine output. The lactate elevated in group H than group C (P < 0.05, and the PH showed metabolic acidosis in group H (P < 0.05. The mixed venous oxygen saturation decreased in group H than group C (P < 0.05. The number of transfused packed red blood cells was lower in group H than group C (P < 0.05. The hematocrit was higher in group H than group C (P < 0.05. The urine output was lower in group H than group C (P < 0.05. Conclusions: Hemofiltration during cardiopulmonary bypass leads to hemoconcentration, elevated lactate level and increased inotropic support. There are some recommendations for hemofiltration: First; Hemofiltration should be limited for patients with impaired renal function, positive fluid balance, reduced response to diuretics or prolonged bypass time more than 2 hours. Second; Minimal amount of fluids should be administered to maintain adequate cardiac output and reduction of priming volumes is preferable to maintain controlled hemodilution. Third; it should be done before weaning of or after cardiopulmonary bypass and not during the whole time of cardiopulmonary bypass.

Statutory acts concerning human health care, including those pertinent to cardiopulmonary resuscitation and those providing for the responsibility of medical workers in some cases were analyzed. A number of discrepancies in various legal acts concerning human death verification and resuscitative measures were identified. The analysis has revealed the aspects of cardiopulmonary resuscitation, which are, from the point of view of legislation, most important for the physician.

Fluid distribution kinetics during cardiopulmonary bypass

Directory of Open Access Journals (Sweden)

Mattias Törnudd

2014-08-01

Full Text Available OBJECTIVE: The purpose of this study was to examine the isovolumetric distribution kinetics of crystalloid fluid during cardiopulmonary bypass. METHODS: Ten patients undergoing coronary artery bypass grafting participated in this prospective observational study. The blood hemoglobin and the serum albumin and sodium concentrations were measured repeatedly during the distribution of priming solution (Ringer's acetate 1470 ml and mannitol 15% 200 ml and initial cardioplegia. The rate of crystalloid fluid distribution was calculated based on 3-min Hb changes. The preoperative blood volume was extrapolated from the marked hemodilution occurring during the onset of cardiopulmonary bypass. Clinicaltrials.gov: NCT01115166. RESULTS: The distribution half-time of Ringer's acetate averaged 8 minutes, corresponding to a transcapillary escape rate of 0.38 ml/kg/min. The intravascular albumin mass increased by 5.4% according to mass balance calculations. The preoperative blood volume, as extrapolated from the drop in hemoglobin concentration by 32% (mean at the beginning of cardiopulmonary bypass, was 0.6-1.2 L less than that estimated by anthropometric methods (p<0.02. The mass balance of sodium indicated a translocation from the intracellular to the extracellular fluid space in 8 of the 10 patients, with a median volume of 236 ml. CONCLUSIONS: The distribution half-time of Ringer's solution during isovolumetric cardiopulmonary bypass was 8 minutes, which is the same as for crystalloid fluid infusions in healthy subjects. The intravascular albumin mass increased. Most patients were hypovolemic prior to the start of anesthesia. Intracellular edema did not occur.

In effort to improve chest compression quality among health care providers, numerous feedback devices have been developed. Few studies, however, have focused on the use of cardiopulmonary resuscitation feedback devices for infants and children. This study evaluated the quality of chest compressions with standard team-leader coaching, a metronome (MetroTimer by ONYX Apps), and visual feedback (SkillGuide Cardiopulmonary Feedback Device) during simulated infant cardiopulmonary resuscitation. Seventy voluntary health care providers who had recently completed Pediatric Advanced Life Support or Basic Life Support courses were randomized to perform simulated infant cardiopulmonary resuscitation into 1 of 3 groups: team-leader coaching alone (control), coaching plus metronome, or coaching plus SkillGuide for 2 minutes continuously. Rate, depth, and frequency of complete recoil during cardiopulmonary resuscitation were recorded by the Laerdal SimPad device for each participant. American Heart Association-approved compression techniques were randomized to either 2-finger or encircling thumbs. The metronome was associated with more ideal compression rate than visual feedback or coaching alone (104/min vs 112/min and 113/min; P = 0.003, 0.019). Visual feedback was associated with more ideal depth than auditory (41 mm vs 38.9; P = 0.03). There were no significant differences in complete recoil between groups. Secondary outcomes of compression technique revealed a difference of 1 mm. Subgroup analysis of male versus female showed no difference in mean number of compressions (221.76 vs 219.79; P = 0.72), mean compression depth (40.47 vs 39.25; P = 0.09), or rate of complete release (70.27% vs 64.96%; P = 0.54). In the adult literature, feedback devices often show an increase in quality of chest compressions. Although more studies are needed, this study did not demonstrate a clinically significant improvement in chest compressions with the addition of a metronome or visual

Workplace Health Promotion: Assessing the Cardiopulmonary Risks of the Construction Workforce in Hong Kong.

Sze Pui Pamela Tin

Full Text Available Health needs of different employee subgroups within an industry can differ. We report the results of a workplace cardiopulmonary risk assessment targeting workers and support staff in the construction industry.A free worksite-based cardiopulmonary risk assessment for 1,903 workers on infrastructural contracts across Hong Kong was initiated in May 2014. Cardiopulmonary risk screening was performed in 60-minute blocks for approximately 30 workers/block with individualized feedback and lifestyle counseling. Risk profiles stratified by occupational roles are differentiated using the χ2-test for categorical and Student's t-test for continuous variables.Most construction workers and clerks/professionals were male (83.2% and 71.2%, respectively and Chinese (78.7% and 90.9%, respectively. Construction workers were older (mean: 44.9 years, SD 11.5 and less well-educated (6.1% received tertiary education than clerks/professionals (35.0 years, 10.7; 72.6% received tertiary education, but more likely to be hypertensive (22.6% vs. 15.4%, p<0.001, overweight/obese (71.7% vs. 56.6%, p<0.001, centrally obese (53.1% vs. 35.5%, p<0.001, and have undesirable levels of high-density lipoprotein (41.6% vs. 35.8%, p<0.05 and diabetic levels of non-fasting blood glucose (4.3% vs. 1.6%, p<0.05. Up to 12.6% of construction workers and 9.7% of office clerks/professions had three or more metabolic syndrome risk factors. While construction workers were more likely than clerks/professionals to be daily smokers, they reported better work-related physical activity and diet.Simple worksite health risk screening can identify potentially high-cardiopulmonary-risk construction industry employee subgroups for onward confirmatory referral. Separate cardiopulmonary health promotion strategies that account for the varying lifestyle profiles of the two employee subgroups in the industry appear justified.

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

Full Text Available Natalie R Stokes,1 Brett W Dietz,1 Jackson J Liang2 1Perelman School of Medicine, University of Pennsylvania, 2Cardiovascular Division, Hospital of the University of Pennsylvania, Philadelphia, PA, USAAbstract: Dyspnea is a common chief complaint in the emergency department, with over 4 million visits annually in the US. Establishing the correct diagnosis can be challenging, because the subjective sensation of dyspnea can result from a wide array of underlying pathology, including pulmonary, cardiac, neurologic, psychiatric, toxic, and metabolic disorders. Further, the presence of dyspnea is linked with increased mortality in a variety of conditions, and misdiagnosis of the cause of dyspnea leads to poor patient-level outcomes. In combination with the history and physical, efficient, and focused use of laboratory studies, the various cardiopulmonary biomarkers can be useful in establishing the correct diagnosis and guiding treatment decisions in a timely manner. Use and interpretation of such tests must be guided by the clinical context, as well as an understanding of the current evidence supporting their use. This review discusses current standards and research regarding the use of established and emerging cardiopulmonary laboratory markers in the evaluation of acute dyspnea, focusing on recent evidence assessing the diagnostic and prognostic utility of various tests. These markers include brain natriuretic peptide (BNP and N-terminal prohormone (NT-proBNP, mid-regional peptides proatrial NP and proadrenomedullin, cardiac troponins, D-dimer, soluble ST2, and galectin 3, and included is a discussion on the use of arterial and venous blood gases.Keywords: cardiopulmonary, emergency, heart failure, troponin, BNP, galectin 3, MR-proANP, MR-proADM

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

The disease of critically ill patients was with rapid changes, and at any time faced the risk of emergency. The current commonly used rescue vehicles were larger and bulky implementation, which were not conducive to the operation, therefore the design of a portable rescue vehicle was needed. This new type of rescue vehicle is multi-layer folding structure, with small footprint, large storage space, so a variety of first aid things can be classified and put, easy to be cleaned and disinfected. In the rescue process, the portable rescue vehicles can be placed in the required position; box of various emergency items can be found at a glance with easy access; the height of the infusion stand can adjust freely according to the user height; the rescue vehicle handle can be easy to pull and adjust accord with human body mechanics principle. The portable rescue vehicle facilitates the operation of medical staff, and is worthy of clinical application.

Cardiopulmonary Resuscitation in Resource-limited Health Systems-Considerations for Training and Delivery.

Friesen, Jason; Patterson, Dean; Munjal, Kevin

2015-02-01

In the past 50 years, cardiopulmonary resuscitation (CPR) has gained widespread recognition as a life-saving skill that can be taught successfully to the general public. Cardiopulmonary resuscitation can be considered a cost-effective intervention that requires minimal classroom training and low-cost equipment and supplies; it is commonly taught throughout much of the developed world. But, the simplicity of CPR training and its access for the general public may be misleading, as outcomes for patients in cardiopulmonary arrest are poor and survival is dependent upon a comprehensive "chain-of-survival," which is something not achieved easily in resource-limited health care settings. In addition to the significant financial and physical resources needed to both train and develop basic CPR capabilities within a community, there is a range of ethical questions that should also be considered. This report describes some of the financial and ethical challenges that might result from CPR training in low- and middle-income countries (LMICs). It is determined that for many health care systems, CPR training may have financial and ethically-deleterious, unintended consequences. Evidence shows Basic Life Support (BLS) skills training in a community is an effective intervention to improve public health. But, health care systems with limited resources should include CPR training only after considering the full implications of that intervention.

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

delta-Opioid-induced pharmacologic myocardial hibernation during cardiopulmonary resuscitation.

Fang, Xiangshao; Tang, Wanchun; Sun, Shijie; Weil, Max Harry

2006-12-01

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

A focus group study of the first moments in an underground mine emergency response was conducted by the National Institute for Occupational Safety and Health (NIOSH), Office for Mine Safety and Health Research. Participants in the study included mine rescue team members, team trainers, mine officials, state mining personnel, and individual mine managers. A subset of the data consists of responses from participants with mine rescue backgrounds. These responses were noticeably different from those given by on-site emergency personnel who were at the mine and involved with decisions made during the first moments of an event. As a result, mine rescue team behavior data were separated in the analysis and are reported in this article. By considering the responses from mine rescue team members and trainers, it was possible to sort the data and identify seven key areas of importance to them. On the basis of the responses from the focus group participants with a mine rescue background, the authors concluded that accurate and complete information and a unity of purpose among all command center personnel are two of the key conditions needed for an effective mine rescue operation.

Business rescue decision making through verifier determinants – ask the specialists

Directory of Open Access Journals (Sweden)

Marius Pretorius

2013-11-01

Full Text Available Orientation: Business rescue has become a critical part of business strategy decision making, especially during economic downturns and recessions. Past legislation has generally supported creditor-friendly regimes, and its mind-set still applies which increases the difficulty of such turnarounds. There are many questions and critical issues faced by those involved in rescue. Despite extensive theory in the literature on failure, there is a void regarding practical verifiers of the signs and causes of venture decline, as specialists are not forthcoming about what they regard as their “competitive advantage”. Research purpose: This article introduces the concept and role of “verifier determinants” of early warning signs, as a tool to confirm the causes of decline in order to direct rescue strategies and, most importantly, reduce time between the first observation and the implementation of the rescue. Motivation for the study: Knowing how specialist practitioners confirm causes of business decline could assist in deciding on strategies for the rescue earlier than can be done using traditional due diligence which is time consuming. Reducing time is a crucial element of a successful rescue. Research design and approach: The researchers interviewed specialist practitioners with extensive experience in rescue and turnaround. An experimental design was used to ensure the specialists evaluated the same real cases to extract their experiences and base their decisions on. Main findings: The specialists confirmed the use of verifier determinants and identified such determinants as they personally used them to confirm causes of decline. These verifier determinants were classified into five categories; namely, management, finance, strategic, banking and operations and marketing of the ventures under investigation. The verifier determinants and their use often depend heavily on subconscious (non-factual information based on previous experiences

Updated life-support guidelines were published by the European Resuscitation Council (ERC) in 2010, increasing the required depth and rate of chest compression delivery. This study sought to determine the impact of these guidelines on rescuer fatigue and cardiopulmonary resuscitation (CPR) performance. 62 Health science students performed 5 min of conventional CPR in accordance with the 2010 ERC guidelines. A SkillReporter manikin was used to objectively assess temporal change in determinants of CPR quality. Participants subjectively reported their end-fatigue levels, using a visual analogue scale, and the point at which they believed fatigue was affecting CPR delivery. 49 (79%) participants reported that fatigue affected their CPR performance, at an average of 167 s. End fatigue averaged 49.5/100 (range 0-95). The proportion of chest compressions delivered correctly decreased from 52% in min 1 to 39% in min 5, approaching significance (p=0.071). A significant decline in chest compressions reaching the recommended depth occurred between the first (53%) and fifth (38%) min (p=0.012). Almost half this decline (6%) was between the first and second minutes of CPR. Neither chest compression rate, nor rescue breath volume, were affected by rescuer fatigue. Fatigue affects chest compression delivery within the second minute of CPR under the 2010 ERC guidelines, and is poorly judged by rescuers. Rescuers should, therefore, be encouraged to interchange after 2 min of CPR delivery. Team leaders should be advised to not rely on rescuers to self-report fatigue, and should, instead, monitor for its effects.

Full Text Available Abstract Background Left ventricular dysfunction is common after coronary artery bypass graft and valve replacement surgeries and is often treated with inotropic drugs to maintain adequate hemodynamic status. In this study, we aimed to identify the demographic, clinical, laboratory, echocardiographic and hemodynamic factors that are associated with use of inotropic drugs in patients undergoing concomitant coronary artery bypass graft and aortic valve replacement surgery. Methods The study included 97 patients who had undergone concomitant coronary artery bypass graft and aortic valve replacement at Regions Hospital, University of Minnesota Medical School from January 2006 to December 2008. All data were collected retrospectively after reviewing electronic medical records. Inotropic support was defined as the use of dopamine [greater than or equal to] 5 ug/kg/min; any dose of epinephrine, norepinephrine, dobutamine, and milrinone at the separation from cardiopulmonary bypass. Results Inotropic support was used in a total of 50 patients (52% at the separation from cardiopulmonary bypass. Average age of the patients requiring inotropic support was 72.2 +/- 8.8 years. The study identified four significant, independent predictors of inotrope use: (1 Cardiac index [less than or equal to]2.5 L/min/m2, (2 LVEDP [greater than or equal to] 20 mm Hg, (3 LVEF [less than or equal to]40%, and (4 CKD stage 3 to 5. Conclusion We identified four independent risk factors for postoperative use of inotropic support in patients undergoing concomitant coronary artery bypass graft and arotic valve replacement surgery at the separation from cardiopulmonary bypass. The study results will be helpful to prospectively identify patients who will likely to require inotropic support at the separation from cardiopulmonary bypass.

Do Radiologists Want/Need Training in Cardiopulmonary Resuscitation?

2003-01-01

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

It seems reasonable that radiological Dept. themselves should organize courses in order to cope with their specific situations.

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

Conservation and the 4 Rs, which are rescue, rehabilitation, release, and research.

Vertebrate animals can be injured or threatened with injury through human activities, thus warranting their "rescue." Details of wildlife rescue, rehabilitation, release, and associated research (our 4 Rs) are often recorded in large databases, resulting in a wealth of available information. This information has huge research potential and can contribute to understanding of animal biology, anthropogenic impacts on wildlife, and species conservation. However, such databases have been little used, few studies have evaluated factors influencing success of rehabilitation and/or release, recommended actions to conserve threatened species have rarely arisen, and direct benefits for species conservation are yet to be demonstrated. We therefore recommend that additional research be based on data from rescue, rehabilitation, and release of animals that is broader in scope than previous research and would have community support. © 2017 Society for Conservation Biology.

Overweight, obesity, and cardiovascular disease risk factors are prevalent among firefighters in some developed countries. It is unclear whether physical activity and cardiopulmonary fitness reduce cardiovascular disease risk and the cardiovascular workload at work in firefighters. The present study investigated the relationship between leisure-time physical activity, cardiopulmonary fitness, cardiovascular disease risk factors, and cardiovascular workload at work in firefighters in Hong Kong. Male firefighters (n = 387) were randomly selected from serving firefighters in Hong Kong (n = 5,370) for the assessment of cardiovascular disease risk factors (obesity, hypertension, diabetes mellitus, dyslipidemia, smoking, known cardiovascular diseases). One-third (Target Group) were randomly selected for the assessment of off-duty leisure-time physical activity using the short version of the International Physical Activity Questionnaire. Maximal oxygen uptake was assessed, as well as cardiovascular workload using heart rate monitoring for each firefighter for four "normal" 24-hour working shifts and during real-situation simulated scenarios. Overall, 33.9% of the firefighters had at least two cardiovascular disease risk factors. In the Target Group, firefighters who had higher leisure-time physical activity had a lower resting heart rate and a lower average working heart rate, and spent a smaller proportion of time working at a moderate-intensity cardiovascular workload. Firefighters who had moderate aerobic fitness and high leisure-time physical activity had a lower peak working heart rate during the mountain rescue scenario compared with firefighters who had low leisure-time physical activities. Leisure-time physical activity conferred significant benefits during job tasks of moderate cardiovascular workload in firefighters in Hong Kong.

Precision Rescue Behavior in North American Ants

Directory of Open Access Journals (Sweden)

Katherine Taylor

2013-07-01

Full Text Available Altruistic behavior, in which one individual provides aid to another at some cost to itself, is well documented. However, some species engage in a form of altruism, called rescue, that places the altruist in immediate danger. Here we investigate one such example, namely rescuing victims captured by predators. In a field experiment with two North American ant species, Tetramorium sp. E and Prenolepis imparis, individuals were held in artificial snares simulating capture. T. sp. E, but not P. imparis, exhibited digging, pulling, and snare biting, the latter precisely targeted to the object binding the victim. These results are the first to document precision rescue in a North American ant species; moreover, unlike rescue in other ants, T. sp. E rescues conspecifics from different colonies, mirroring their atypical social behavior, namely the lack of aggression between non-nestmate (heterocolonial conspecifics. In a second, observational study designed to demonstrate rescue from an actual predator, T. sp. E victims were dropped into an antlion's pit and the behavior of a single rescuer was observed. Results showed that T. sp. E not only attempted to release the victim, but also risked attacking the predator, suggesting that precision rescue may play an important role in this species' antipredator behavior.

For cardiac arrests witnessed at home, the witness is usually a middle-aged or older housewife. We compared the quality of cardiopulmonary resuscitation (CPR) performance of bystanders trained with the newly developed telephone-basic life support (T-BLS) program and those trained with standard BLS (S-BLS) training programs. Twenty-four middle-aged and older housewives without previous CPR education were enrolled and randomized into two groups of BLS training programs. The T-BLS training program included concepts and current instruction protocols for telephone-assisted CPR, whereas the S-BLS training program provided training for BLS. After each training course, the participants simulated CPR and were assisted by a dispatcher via telephone. Cardiopulmonary resuscitation quality was measured and recorded using a mannequin simulator. The primary outcome was total no-flow time (>1.5 seconds without chest compression) during simulation. Among 24 participants, two (8.3%) who experienced mechanical failure of simulation mannequin and one (4.2%) who violated simulation protocols were excluded at initial simulation, and two (8.3%) refused follow-up after 6 months. The median (interquartile range) total no-flow time during initial simulation was 79.6 (66.4-96.9) seconds for the T-BLS training group and 147.6 (122.5-184.0) seconds for the S-BLS training group (P trained with the T-BLS training program showed shorter no-flow time and fewer interruptions during bystander CPR simulation assisted by a dispatcher.

Myxedema Coma with Reversible Cardiopulmonary Failure: a Rare Entity in 21St Century.

Dhakal, Prajwal; Pant, Manisha; Acharya, Pranab Sharma; Dahal, Sumit; Bhatt, Vijaya Raj

2015-09-01

Myxedema coma, a rare entity in 21st century in developed nations, is a decompensated phase of hypothyroidism with high mortality rates. We describe a young woman with myxedema, who developed respiratory failure, congestive heart failure and significant pericardial effusion, some of the uncommon manifestations. Decreased cardiac contractility can result in cardiomyopathy and heart failure. As illustrated by this case, myxedema can also result in significant pericardial effusion due to increased vascular permeability. Myxedema can further be complicated by alveolar hypoventilation and respiratory failure secondary to the lack of central drive as well as respiratory muscle weakness. Prompt therapy with thyroid hormone replacement, glucocorticoid therapy, aggressive supportive care and management of the precipitating event can save lives and reverse the cardiopulmonary symptoms, as in our patient. Hence, physicians should have a high index of suspicion for myxedema coma in patients with unexplained cardiopulmonary failure. Our report is, therefore, aimed at bringing awareness about the rare but fatal manifestations of myxedema coma.

Joseph Conrad's tormented Rescue (fantasy).

Science.gov (United States)

Freedman, William

2014-02-01

Joseph Conrad was a notoriously tormented writer for whom the creative act was often a punishment severe enough to drive him into paralyzing depressions that delayed the completion of his novels, sometimes for years. By far the most agonizing of these projects was The Rescue, a novel he began in 1898, abandoned a year later, tried unsuccessfully to continue several times over the next two decades, but was only able to resume in 1918 and to complete, after another tortured two-year struggle, in 1920. An explanation for this incapacity, that is powerfully suggested by the novel's evocative title and perhaps unintentionally ironic subtitle (A Romance of the Shallows) has not yet been explored. Using Freud's 1910 essay on the rescue fantasy, "Contributions to the Psychology of Love: A Special Type of Choice of Object Made by Men," and Emanuel Berman's instructive revision and expansion of the concept in his 2003 American Imago essay, "Ferenczi, Rescue, and Utopia," I argue that a substantial explanation for Conrad's tormented history with The Rescue is ascribable to its quite remarkably faithful treatment of a rescue fantasy with deep and disabling resonance for its author. More specifically, the difficulty was compounded by the novel's dramatization of the soul-crushing conflict between two such fantasies: one in the service of the masculine ideal of unflinching dedication to a heroic purpose, the other promising satisfaction to the equally potent demands of emotional and sexual desire. Features of Conrad's narrative fit so tightly and consistently with the theory as Freud (and Abraham) proposed and as Berman elaborated it that The Rescue offers itself as one of those rare and reinforcing instances wherein the literary text seems to validate the psychoanalytic theory at least as persuasively as the theory "understands" the text.

Cardiopulmonary Resuscitation in Microgravity: Efficacy in the Swine During Parabolic Flight

Science.gov (United States)

Johnston, Smith L.; Campbell, Mark R.; Billica, Roger D.; Gilmore, Stevan M.

2004-01-01

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

Boulder Food Rescue: An Innovative Approach to Reducing Food Waste and Increasing Food Security.

Science.gov (United States)

Sewald, Craig A; Kuo, Elena S; Dansky, Hana

2018-05-01

Food waste and food insecurity are both significant issues in communities throughout the U.S., including Boulder, Colorado. As much as 40% of the food produced in the U.S. goes uneaten and ends up in landfills. Nearly 13% of people in the Boulder region experience some level of food insecurity. Founded in 2011, Boulder Food Rescue supports community members to create their own food security through a participatory approach to an emergency food system. The organization uses a web-application "robot" to manage a schedule of volunteers. They coordinate with individuals at low-income senior housing sites, individual housing sites, family housing sites, after-school programs, and pre-schools to set up no-cost grocery programs stocked with food from local markets and grocers that would otherwise go to waste. Each site coordinator makes decisions about how, when, and where food delivery and distribution will occur. The program also conducts robust, real-time data collection and analysis. Boulder Food Rescue is a member and manager of the Food Rescue Alliance, and its model has been replicated and adapted by other cities, including Denver, Colorado Springs, Seattle, Jackson Hole, Minneapolis, Binghamton, and in the Philippines. Information for this special article was collected through key informant interviews with current and former Boulder Food Rescue staff and document review of Boulder Food Rescue materials. Boulder Food Rescue's open source software is available to other communities; to date, 40 cities have used the tool to start their own food rescue organizations. Boulder Food Rescue hopes to continue spreading this model to other cities that are considering ways to reduce food waste and increase food security.

Cardiopulmonary laboratory biomarkers in the evaluation of acute dyspnea.

Science.gov (United States)

Stokes, Natalie R; Dietz, Brett W; Liang, Jackson J

2016-01-01

Dyspnea is a common chief complaint in the emergency department, with over 4 million visits annually in the US. Establishing the correct diagnosis can be challenging, because the subjective sensation of dyspnea can result from a wide array of underlying pathology, including pulmonary, cardiac, neurologic, psychiatric, toxic, and metabolic disorders. Further, the presence of dyspnea is linked with increased mortality in a variety of conditions, and misdiagnosis of the cause of dyspnea leads to poor patient-level outcomes. In combination with the history and physical, efficient, and focused use of laboratory studies, the various cardiopulmonary biomarkers can be useful in establishing the correct diagnosis and guiding treatment decisions in a timely manner. Use and interpretation of such tests must be guided by the clinical context, as well as an understanding of the current evidence supporting their use. This review discusses current standards and research regarding the use of established and emerging cardiopulmonary laboratory markers in the evaluation of acute dyspnea, focusing on recent evidence assessing the diagnostic and prognostic utility of various tests. These markers include brain natriuretic peptide (BNP) and N-terminal prohormone (NT-proBNP), mid-regional peptides proatrial NP and proadrenomedullin, cardiac troponins, D-dimer, soluble ST2, and galectin 3, and included is a discussion on the use of arterial and venous blood gases.

The Use of Extracorporeal Membrane Oxygenation-Cardiopulmonary Resuscitation in Prolonged Cardiac Arrest in Pediatric Patients: Is it Time to Expand It?

Science.gov (United States)

Absi, Mohammed; Kumar, Susheel Tk; Sandhu, Hitesh

2017-09-01

Extracorporeal membrane oxygenation was instituted as an aid to in-hospital cardiopulmonary resuscitation (E-CPR) nearly 23 years ago, this led to remarkable improvement in survival considering the mortality rate associated with conventional cardiopulmonary resuscitation (CPR). Given this success, one begins to wonder whether the time has come for expanding the use of E-CPR to outside hospital cardiac arrests especially in the light of development of newer extracorporeal life support devices that are small, mobile, and easy to assemble. This editorial will review recent studies on this subject and address some key guidelines and limitations of this evolving and promising technology.

To investigate the effectiveness of brief bedside "booster" cardiopulmonary resuscitation (CPR) training to improve CPR guideline compliance of hospital-based pediatric providers. Prospective, randomized trial. General pediatric wards at Children's Hospital of Philadelphia. Sixty-nine Basic Life Support-certified hospital-based providers. CPR recording/feedback defibrillators were used to evaluate CPR quality during simulated pediatric arrest. After a 60-sec pretraining CPR evaluation, subjects were randomly assigned to one of three instructional/feedback methods to be used during CPR booster training sessions. All sessions (training/CPR manikin practice) were of equal duration (2 mins) and differed only in the method of corrective feedback given to participants during the session. The study arms were as follows: 1) instructor-only training; 2) automated defibrillator feedback only; and 3) instructor training combined with automated feedback. Before instruction, 57% of the care providers performed compressions within guideline rate recommendations (rate >90 min(-1) and 38 mm); and 36% met overall CPR compliance (rate and depth within targets). After instruction, guideline compliance improved (instructor-only training: rate 52% to 87% [p .01], and overall CPR compliance, 43% to 78% [p CPR compliance, 35% to 96% [p training combined with automated feedback: rate 48% to 100% [p CPR compliance, 30% to 100% [p CPR instruction, most certified Pediatric Basic Life Support providers did not perform guideline-compliant CPR. After a brief bedside training, CPR quality improved irrespective of training content (instructor vs. automated feedback). Future studies should investigate bedside training to improve CPR quality during actual pediatric cardiac arrests.

Detection of Cardiopulmonary Activity and Related Abnormal Events Using Microsoft Kinect Sensor.

2018-03-20

Monitoring of cardiopulmonary activity is a challenge when attempted under adverse conditions, including different sleeping postures, environmental settings, and an unclear region of interest (ROI). This study proposes an efficient remote imaging system based on a Microsoft Kinect v2 sensor for the observation of cardiopulmonary-signal-and-detection-related abnormal cardiopulmonary events (e.g., tachycardia, bradycardia, tachypnea, bradypnea, and central apnoea) in many possible sleeping postures within varying environmental settings including in total darkness and whether the subject is covered by a blanket or not. The proposed system extracts the signal from the abdominal-thoracic region where cardiopulmonary activity is most pronounced, using a real-time image sequence captured by Kinect v2 sensor. The proposed system shows promising results in any sleep posture, regardless of illumination conditions and unclear ROI even in the presence of a blanket, whilst being reliable, safe, and cost-effective.

Emergency rescue in accidents with HDR afterloading units

International Nuclear Information System (INIS)

Kaulich, T.W.; Nuesslin, F.; Becker, G.; Lamprecht, U.; Bamberg, M.

1999-01-01

Problem: HDR brachyradiotherapy has minimized the exposure to radiation of the personnel working in this field. Nonetheless there are periodically reported troubles with afterloading units concerning the retraction of sources that require immediate action for the limitation of possible damage. Legal Principles according to the German Regulation Concerning Protection against Radiation (Strahlenschutzverordnung=StrlSchV): If in afterloading brachyradiotherapy the radiation source remains extended through malfunction we deal with an emergency according to the StrlSchV. The rescue personnel should be chosen in accordance with Paragraph 50 StrlSchV. Organization of the Rescue of the Patient: The quickest possible rescue of a patient in an emergency demands an unequivocal definition of responsibilities. Our recommendations in this instance: The physicist is responsible for the organization of the emergency rescue. The radiation oncologist in charge informs himself about the necessary emergency measures before starting the treatment and carries out the emergency rescue. If the physicist diagnoses a failure in the retraction of the source he tries to remove the failure. If he doesn't succeed in retracting the source the radiation oncologist carries out the rescue of the patient. The organizational structure of the clinic allowing, the emergency physician should invariably be the physician who placed the applicator. In the emergency rescue the radiation oncologist should be protected by a lead barrier and use manipulators. Dose Assessment in Personnel and Patient: The radiation exposure of the rescue personnel is calculated from the photon-equivalence dose H x with the help of the dose-rate constant of 192 Ir. According to the same procedure there can be evaluated the local radiation exposure of the patient concerned. Conclusions: Generally speaking, all considerations regarding the topic of emergency rescue should always start out from a worst-case scenario. Of all the

Nurses' knowledge and skill retention following cardiopulmonary resuscitation training: a review of the literature.

Science.gov (United States)

Hamilton, Rosemary

2005-08-01

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

2013-01-01

To describe the successful application of CPR in a geriatric chinchilla employing basic and advanced life support measures during cardiopulmonary arrest (CPA). A 13-year-old female intact chinchilla presented to a general and multispecialty referral hospital for a dental procedure. During recovery from anesthesia the patient suffered CPA and CPR was initiated. Noninvasive positive pressure mask ventilation was initiated and external chest compressions were performed. An 18-Ga needle was introduced into the medullary cavity of the right humerus as an intraosseous catheter and provided access for administration of drugs and fluids. After return of spontaneous circulation was noted mannitol was administered via the intraosseous catheter to alleviate suspected increased intracranial pressure. Clinical improvement was noted shortly after administration. Monitoring during the recovery period showed a normal sinus cardiac rhythm and a SpO₂ of 100% while on supplemental oxygen. Neurologic function continued to improve over the following hours. Oxygen therapy was provided via an oxygen cage, and administration of antimicirobials, gastrointestinal protectants, and nutritional supplementation were part of the post resuscitation care. Oxygen therapy was discontinued after 24 hours, during which time normal behaviors were observed and neurologic status was considered appropriate. The patient was discharged 48 hours after CPA. Published reports from clinical practice on the outcomes of CPR for exotic small mammals are limited. This report details the successful outcome of the use of combined basic and advanced life support measures for the provision of CPR in a chinchilla. This report also highlights the utility of an intraosseous catheter for administration of drugs and fluids novel to this species during resuscitation and recovery. To the authors' knowledge this is the first published report of successful CPR following CPA in a geriatric chinchilla. © Veterinary Emergency

Cardiopulmonary fitness and muscle strength in patients with osteogenesis imperfecta type I.

To evaluate cardiopulmonary function, muscle strength, and cardiopulmonary fitness (VO 2 peak) in patients with osteogenesis imperfecta (OI). In 17 patients with OI type I (mean age 13.3 +/- 3.9 years) cardiopulmonary function was assessed at rest using spirometry, plethysmography, electrocardiography, and echocardiography. Exercise capacity was measured using a maximal exercise test on a bicycle ergometer and an expired gas analysis system. Muscle strength in shoulder abductors, hip flexors, ankle dorsal flexor, and grip strength were measured. All results were compared with reference values. Cardiopulmonary function at rest was within normal ranges, but when it was compared with normal height for age and sex, vital capacities were reduced. Mean absolute and relative VO 2 peak were respectively -1.17 (+/- 0.67) and -1.41 (+/- 1.52) standard deviations lower compared with reference values ( P exercise tolerance and muscle strength were significantly reduced in patients with OI, which might account for their increased levels of fatigue during activities of daily living.

Patients with advanced liver disease may develop portal hypertension that can result in variceal haemorrhage. Beta-blockers reduce portal pressure and minimise haemorrhage risk. These medications may attenuate measures of cardiopulmonary performance, such as the ventilatory threshold and peak oxygen uptake measured via cardiopulmonary exercise testing. To determine the effect of beta-blockers on cardiopulmonary exercise testing variables in patients with advanced liver disease. This was a cross-sectional analysis of 72 participants who completed a cardiopulmonary exercise test before liver transplantation. All participants remained on their usual beta-blocker dose and timing prior to the test. Variables measured during cardiopulmonary exercise testing included the ventilatory threshold, peak oxygen uptake, heart rate, oxygen pulse, the oxygen uptake efficiency slope and the ventilatory equivalents for carbon dioxide slope. Participants taking beta-blockers (n = 28) had a lower ventilatory threshold (P advanced liver disease taking beta-blockers compared to those not taking the medication. This may incorrectly risk stratify patients on beta-blockers and has implications for patient management before and after liver transplantation. The oxygen uptake efficiency slope was not influenced by beta-blockers and may therefore be a better measure of cardiopulmonary performance in this patient population. © 2017 John Wiley & Sons Ltd.

Research conducted on young Israeli travellers has pointed to high substance usage rates. For some drug-using backpackers, actual extraction and rescue from their trip abroad is necessary. This study represents a first attempt to explore the influence of geographic region in which rescue occurs, cause for rescue and gender and age differences among Israeli rescuees. Sub-analysis of all logs of individual rescuees during a 5-year period from 2011 to 2016 ( N  = 86) included 66 men and 20 women, with an average age of 27.83 (SD = 7.86). The findings demonstrate that Israelis are most frequently rescued from South and Southeast Asia (57%) followed by Europe (22%), South America (17%), North America (2.3%) and Africa (1.2%). India was the country with the highest rate of rescue incidents ( N  = 36) followed by Thailand ( N  = 8) and the Netherlands ( N  = 5). The most common cause for rescue was substance abuse (87%). However, significant regional differences were found based on the variable of age ( F  = 3.21, df = 3,50, P  young travellers should be taken into consideration when thinking about induced acute psychosis caused by substance use. Policymakers need to consider prevention and harm reduction interventions relevant to this risk group. © International Society of Travel Medicine, 2017. Published by Oxford University Press.

Cardiopulmonary resuscitation (CPR) increases the probability of survival of a person with cardiac arrest. Repeating training helps staff retain knowledge in CPR and in use of automated external defibrillators (AEDs). Retention of knowledge and skills during and after training in CPR is difficult and requires systematic training with appropriate methodology. The aim of this study was to determine the effect of basic life-support (BLS) training on the attitudes of health-care providers toward initiating CPR and on use of AEDs, and to investigate the factors that influence these attitudes. A quasi-experimental study was conducted in two groups: health-care providers who had just attended a BLS-AED course (post-BLS group, n = 321), and those who had not (pre-BLS group, n = 421). All participants had previously received BLS training. Both groups were given a validated questionnaire to evaluate the status of life-support education and certification, attitudes toward use of CPR and AED and concerns regarding use of CPR and AED. Multiple linear regression analyses were applied to identify significant predictors of the attitude and concern scores. Overall positive attitudes were seen in 53.4% of pre-BLS respondents and 64.8% of post-BLS respondents (χ 2  = 9.66, p = 0.002). Positive attitude was significantly predicted by the recent completion of BLS training (β = 5.15, p attitudes toward CPR performance and the use of AEDs. Training that addressed the concerns of health-care workers could further improve these attitudes.

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

Sung, Dyi-Shiang; Hsieh, Kai-Sheng

2007-01-01

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

Vukmir, R B

2004-05-01

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

Ketamine has no effect on oxygenation indices following elective coronary artery bypass grafting under cardiopulmonary bypass

2011-01-01

Full Text Available Cardiopulmonary bypass is known to elicit systemic inflammatory response syndrome and organ dysfunction. This can result in pulmonary dysfunction and deterioration of oxygenation after cardiac surgery and cardiopulmonary bypass. Previous studies have reported varying results on anti-inflammatory strategies and oxygenation after cardiopulmonary bypass. Ketamine administered as a single dose at induction has been shown to reduce the pro-inflammatory serum markers in patients undergoing cardiopulmonary bypass. Therefore we investigated if ketamine can result in better oxygenation in these patients. This was a prospective randomized blinded study. Eighty consecutive adult patients undergoing elective coronary artery bypass grafting under cardiopulmonary bypass were included in the study. Patients were divided into two groups. Patients in ketamine group received 1mg/kg of ketamine intravenously at induction of anesthesia. Control group patients received an equal volume of saline. All patients received standard anesthesia, operative and postoperative care.Paired t test and independent sample t test were used to compare the inter-group and between group oxygenation indices respectively. Oxygenation index and duration of ventilation were analyzed. Deterioration of oxygenation index was noted in both the groups after cardiopulmonary bypass. However, there was no significant difference in the oxygenation index at various time points after cardiopulmonary bypass or the duration of ventilation between the two groups. This study shows that the administered as a single dose at induction does not result in better oxygenation after cardiopulmonary bypass.

2016-01-01

Background. Basic life support (BLS) training with hands-on practice can improve performance during simulated cardiac arrest, although the optimal duration for BLS training is unknown. This study aimed to assess the effectiveness of various BLS training durations for acquiring cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) skills. Methods. We randomised 485 South Korean nonmedical college students into four levels of BLS training: level 1 (40 min), level 2 (80 min), level 3 (120 min), and level 4 (180 min). Before and after each level, the participants completed questionnaires regarding their willingness to perform CPR and use AEDs, and their psychomotor skills for CPR and AED use were assessed using a manikin with Skill-Reporter™ software. Results. There were no significant differences between levels 1 and 2, although levels 3 and 4 exhibited significant differences in the proportion of overall adequate chest compressions (p CPR and use AEDs (all, p training provided a moderate level of skill for performing CPR and using AEDs. However, high-quality skills for CPR required longer and hands-on training, particularly hands-on training with AEDs. PMID:27529066

1995-02-01

Active compression-decompression (ACD) cardiopulmonary resuscitation (CPR) utilizes a hand-held suction device with a pressure gauge that enables the operator to compress as well as actively decompress the chest. This new CPR method improves hemodynamic and ventilatory parameters when compared with standard CPR. ACD-CPR is easy to perform but may be more labor intensive. The purpose of this study was to quantify and compare the work required to perform ACD and standard CPR. Cardiopulmonary testing was performed on six basic cardiac life support- and ACD-trained St. Paul, MN fire-fighter personnel during performance of 10 min each of ACD and standard CPR on a mannequin equipped with a compression gauge. The order of CPR techniques was determined randomly with > 1 h between each study. Each CPR method was performed at 80 compressions/min (timed with a metronome), to a depth of 1.5-2 inches, and with a 50% duty cycle. Baseline cardiopulmonary measurements were similar at rest prior to performance of both CPR methods. During standard and ACD-CPR, respectively, rate-pressure product was 18.2 +/- 3.0 vs. 23.8 +/- 1.7 (x 1000, P CPR compared with standard CPR. Both methods require subanaerobic energy expenditure and can therefore be sustained for a sufficient length of time by most individuals to optimize resuscitation efforts. Due to the slightly higher work requirement, ACD-CPR may be more difficult to perform compared with standard CPR for long periods of time, particularly by individuals unaccustomed to the workload requirement of CPR, in general.

Rapid Deterioration of Basic Life Support Skills in Dentists With Basic Life Support Healthcare Provider.

Science.gov (United States)

Nogami, Kentaro; Taniguchi, Shogo; Ichiyama, Tomoko

2016-01-01

The aim of this study was to investigate the correlation between basic life support skills in dentists who had completed the American Heart Association's Basic Life Support (BLS) Healthcare Provider qualification and time since course completion. Thirty-six dentists who had completed the 2005 BLS Healthcare Provider course participated in the study. We asked participants to perform 2 cycles of cardiopulmonary resuscitation on a mannequin and evaluated basic life support skills. Dentists who had previously completed the BLS Healthcare Provider course displayed both prolonged reaction times, and the quality of their basic life support skills deteriorated rapidly. There were no correlations between basic life support skills and time since course completion. Our results suggest that basic life support skills deteriorate rapidly for dentists who have completed the BLS Healthcare Provider. Newer guidelines stressing chest compressions over ventilation may help improve performance over time, allowing better cardiopulmonary resuscitation in dental office emergencies. Moreover, it may be effective to provide a more specialized version of the life support course to train the dentists, stressing issues that may be more likely to occur in the dental office.

Cristiana Araujo G. Ferreira

2014-03-01

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

Physical capacity of rescue personnel in the mining industry

Hunt Andrew P

2008-10-01

Full Text Available Abstract Background The mining industry has one of the highest occupational rates of serious injury and fatality. Mine staff involved with rescue operations are often required to respond to physically challenging situations. This paper describes the physical attributes of mining rescue personnel. Methods 91 rescue personnel (34 ± 8.6 yrs, 1.79 ± 0.07 m, 90 ± 15.0 kg participating in the Queensland Mines Rescue Challenge completed a series of health-related and rescue-related fitness tasks. Health-related tasks comprised measurements of aerobic capacity (VO2max, abdominal endurance, abdominal strength, flexibility, lower back strength, leg strength, elbow flexion strength, shoulder strength, lower back endurance, and leg endurance. Rescue-related tasks comprised an incremental carry (IC, coal shovel (CS, and a hose drag (HD, completed in this order. Results Cardiovascular (VO2max and muscular endurance was average or below average compared with the general population. Isometric strength did not decline with age. The rescue-related tasks were all extremely demanding with heart rate responses averaging greater than 88% of age predicted maximal heart rates. Heart rate recovery responses were more discriminating than heart rates recorded during the tasks, indicating the hose drag as the most physically demanding of the tasks. Conclusion Relying on actual rescues or mining related work to provide adequate training is generally insufficient to maintain, let alone increase, physical fitness. It is therefore recommended that standards of required physical fitness be developed and mines rescue personnel undergo regularly training (and assessment in order to maintain these standards.

Cardiac surgery carried out on cardiopulmonary bypass (CPB) in a pregnant woman is associated with poor neonatal outcomes although maternal outcomes are similar to cardiac surgery in non-pregnant women. Most adverse maternal and fetal outcomes from cardiac surgery during pregnancy are attributed to effects of CPB. The CPB is associated with utero-placental hypoperfusion due to a number of factors, which may translate into low fetal cardiac output, hypoxia and even death. Better maternal and f...

Blood utilization in neonates and infants undergoing cardiac surgery requiring cardiopulmonary bypass.

Science.gov (United States)

Wesley, Mark C; Yuki, Koichi; Daaboul, Dima G; Dinardo, James A

2011-07-01

Neonates and infants undergoing cardiac surgery with cardiopulmonary bypass are exposed to multiple blood products from different donors. The volume of the bypass circuit is often as large as the patient's total blood volume and asanguineous bypass primes are unusual. As a result, blood products are required for the cardiopulmonary bypass prime and are often used to treat the postbypass dilutional coagulopathy. We review clot formation and strength, cardiopulmonary bypass prime considerations, assessment of postbypass coagulopathy, component therapy use, ultrafiltration techniques, and use of antifibrinolytic medications. A combined approach including techniques to minimize the prime volume, utilization of ultrafiltration, administration of antifibrinolytics during surgery, and the proper treatment of the dilutional coagulopathy can limit the transfusion requirements.

Science.gov (United States)

2006-05-01

This publication presents the 2005 American Heart Association (AHA) guidelines for cardiopulmonary resuscitation (CPR) and emergency cardiovascular care (ECC) of the pediatric patient and the 2005 American Academy of Pediatrics/AHA guidelines for CPR and ECC of the neonate. The guidelines are based on the evidence evaluation from the 2005 International Consensus Conference on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations, hosted by the American Heart Association in Dallas, Texas, January 23-30, 2005. The "2005 AHA Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care" contain recommendations designed to improve survival from sudden cardiac arrest and acute life-threatening cardiopulmonary problems. The evidence evaluation process that was the basis for these guidelines was accomplished in collaboration with the International Liaison Committee on Resuscitation (ILCOR). The ILCOR process is described in more detail in the "International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations." The recommendations in the "2005 AHA Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care" confirm the safety and effectiveness of many approaches, acknowledge that other approaches may not be optimal, and recommend new treatments that have undergone evidence evaluation. These new recommendations do not imply that care involving the use of earlier guidelines is unsafe. In addition, it is important to note that these guidelines will not apply to all rescuers and all victims in all situations. The leader of a resuscitation attempt may need to adapt application of the guidelines to unique circumstances. The following are the major pediatric advanced life support changes in the 2005 guidelines: There is further caution about the use of endotracheal tubes. Laryngeal mask airways are acceptable when used by experienced

To systematically review and critically appraise the literature on measurement properties of cardiopulmonary exercise test protocols for measuring aerobic capacity, VO2max, in persons after stroke. PubMed, Embase and Cinahl were searched from inception up to 15 June 2016. A total of 9 studies were identified reporting on 9 different cardiopulmonary exercise test protocols. VO2max measured with cardiopulmonary exercise test and open spirometry was the construct of interest. The target population was adult persons after stroke. We included all studies that evaluated reliability, measurement error, criterion validity, content validity, hypothesis testing and/or responsiveness of cardiopulmonary exercise test protocols. Two researchers independently screened the literature, assessed methodological quality using the COnsensus-based Standards for the selection of health Measurement INstruments checklist and extracted data on measurement properties of cardiopulmonary exercise test protocols. Most studies reported on only one measurement property. Best-evidence synthesis was derived taking into account the methodological quality of the studies, the results and the consistency of the results. No judgement could be made on which protocol is "best" for measuring VO2max in persons after stroke due to lack of high-quality studies on the measurement properties of the cardiopulmonary exercise test.

Studies by different groups on the rescue effect, where unirradiated bystander cells mitigated the damages in the irradiated cells, since its discovery by the authors' group in 2011 were first reviewed. The properties of the rescue effect were then examined using a novel experimental set-up to physically separate the rescue signals from the bystander signals. The authors' results showed that the rescue effect was mediated through activation of the nuclear factor-KB (NF-KB) response pathway in the irradiated cells, and that the NF-KB activation inhibitor BAy -1 1-7082 did not affect the activation of this response pathway in the irradiated cells induced by direct irradiation.

Utilising cardiopulmonary bypass for cancer surgery. Malignancy-induced protein C deficiency and thrombophilia.

LENUS (Irish Health Repository)

Marshall, C

2012-02-03

Cardiopulmonary bypass has evolved over the last 30 years. It is an important tool for the cardiac surgeon today and also has applications in non-cardiac operations such as surgery to extract tumours. Such patients undergoing surgery for cancer may be at an increased risk of a thromboembolic event post surgery, due to disturbances in the normal clotting pathway leading to hypercoagulability. One such disturbance is malignancy-induced Protein C deficiency. A deficiency of Protein C can cause hypercoagulabitity. Recent studies have examined cardiopulmonary bypass and inherited Protein C deficiency. However, surgery for cancer patients with a malignancy-induced Protein C deficiency involving cardiopulmonary bypass has not been reported. Surgery using CPB in these patients may result in increased morbidity and mortality. The objective of this article is to review the literature in order to discuss the occurrence, the aetiology and possible management of cancer patients with malignancy-induced Protein C deficiencies that require cardiopulmonary bypass for their surgery.

To identify clinical and embryological factors that may predict success in rescue intracytoplasmic sperm injection (ICSI) cycles (after total fertilization failure has occurred) and to evaluate the cost effectiveness of rescue ICSI strategy. Additionally, follow-up of 20 rescue ICSI pregnancies is reported. Retrospective analysis of total fertilization failure cycles. University-based tertiary medical center. In total, 92 patients who had undergone conventional in-vitro fertilization (IVF) cycles with total fertilization failure were included. The patients were divided into two subgroups: those who conceived through rescue ICSI and those who did not. The pregnant members of the rescue ICSI subgroup were found to be significantly younger (32.9 ± 4.2 vs. 36.3 ± 4.5, respectively, p = 0.0035,) and to have better-quality embryos than those who did not conceive (cumulative embryo score: 38.3 ± 20.4 vs. 29.3 ± 14.7, p = 0.025). Cost effectiveness analysis showed 25% reduction in the cost per live birth when rescue ICSI is compared to cycle cancellation approach. The pregnancies follow-up did not show adverse perinatal outcome. Rescue ICSI is an option for salvaging IVF cycles complicated by total fertilization failure. Success in rescue ICSI was found to be associated with younger age and higher quality of embryos. Furthermore, the cost effectiveness of rescue ICSI in terms of total fertilization failure was found to be worthwhile.

Full Text Available Background: The work of administrative officers depends a lot on their capability in memorizing. Increased fitness is strongly associated with a better memory. This study was conducted to determine the relationship between cardiopulmonary fitness and short term memory. Methods: This analytical cross sectional study was carried out from August to September 2014. Subjects from administrative offices within Universitas Padjadjaran were chosen by simple random sampling. 101 individuals were selected, comprising of 68 males and 33 females. Data were obtained through Digit Span Test for short term memory and the cardiopulmonary fitness was measured using Harvard Step Test. The VO2 Max obtained was correlated with the Digit Span Test score. Results: The mean for cardiopulmonary fitness of males was found to be 36.1, with standard deviation 8.63, whereas mean cardiopulmonary fitness for females was found to be 32.94, with standard deviation 7.5. For correlation analysis, the result of Spearman’s rank analysis from the study showed that the p-value is 0.00. Comparing to the significance level α=5%, the p value is worth less, thus the null hypothesis, Ho is rejected. Therefore, it could be concluded that there was a relationship between cardiopulmonary fitness and short term memory of male and female administrative officers at Universitas Padjadjaran. Conclusions: There is a relationship between cardiopulmonary fitness and short term memory of male and female administrative officers at Universitas Padjadjaran.

Deciding whether or not to perform a decompressive craniectomy as a life-saving or 'rescue' procedure for a young person with a severe traumatic brain injury provides a good example of the ethical tensions that occur in these situations. Unfortunately, there comes a point when the primary brain injury is so severe that if the patient survives they are likely to remain severely disabled and fully dependent. The health resource implications of this outcome are significant. By using a web-based outcome prediction model this study compares the long-term outcome and designation of two groups of patients. One group had a very severe injury as adjudged by the model and the other group a less severe injury. At 18 month follow-up there were significant differences in outcome and healthcare requirements. This raises important ethical issues when considering life-saving but non-restorative surgical intervention. The discussion about realistic outcome cannot be dichotomised into simply life or death so that the outcome for the patient must enter the equation. As in other 'rescue situations', the utility of the procedure cannot be rationalised on a mere cost-benefit analysis. A compromise has to be reached to determine at what point either the likely outcome would be unacceptable to the person on whom the procedure is being performed or the social utility gained from the rule of rescue intervention fails to justify the utilitarian value and justice of equitable resource allocation.

An infant unable to be weaned from cardiopulmonary bypass after orthotopic heart transplantation was cannulated for extracorporeal membrane oxygenation. During the next 3 days, allograft failure and intracardiac thrombosis necessitated cardiectomy. To provide acute mechanical circulatory support, artificial atrial chambers were constructed with Gore-Tex conduits and PediMag centrifugal pumps were connected to each by Berlin Heart EXCOR cannulae. The PediMag pumps were subsequently exchanged for 10-mL Berlin Heart EXCOR pumps. After 60 days of support by total artificial heart, the patient was bridged successfully to a second heart transplant. Copyright © 2018 The Society of Thoracic Surgeons. Published by Elsevier Inc.

Assessment of nurses’ cardiopulmonary resuscitation knowledge and skills within three district hospitals in Botswana

Science.gov (United States)

2018-01-01

Background Nurses are usually the first to identify the need for and initiate cardiopulmonary resuscitation (CPR) on patients with cardiopulmonary arrest in the hospital setting. Cardiopulmonary resuscitation has been shown to reduce in-hospital deaths when received from adequately trained health care professionals. Aim We aimed to investigate nurses’ retention of CPR knowledge and skills at district hospitals in Botswana. Methods A quantitative, quasi-experimental study was conducted at three hospitals in Botswana. A pre-test, intervention, post-test, and a re-test after 6 months were utilised to determine the retention of CPR knowledge and skills. Non-probability, convenience sampling technique was used to select 154 nurses. The sequences of the test were consistent with the American Heart Association’s 2010 basic life support (BLS) guidelines for health care providers. Data were analysed to compare performance over time. Results This study showed markedly deficient CPR knowledge and skills among registered nurses in the three district hospitals. The pre-test knowledge average score (48%) indicated that the nurses did not know the majority of the BLS steps. Only 85 nurses participated in the re-evaluation test at 6 months. While a 26.4% increase was observed in the immediate post-test score compared with the pre-test, the performance of the available participants dropped by 14.5% in the re-test 6 months after the post-test. Conclusion Poor CPR knowledge and skills among registered nurses may impede the survival and management of cardiac arrest victims. Employers and nursing professional bodies in Botswana should encourage and monitor regular CPR refresher courses. PMID:29781687

Sandia National Laboratories (Sandia) has a long history in developing compact, mobile, very high-speed drilling systems and this technology could be applied to increasing the rate at which boreholes are drilled during a mine accident response. The present study reviews current technical approaches, primarily based on technology developed under other programs, analyzes mine rescue specific requirements to develop a conceptual mine rescue drilling approach, and finally, proposes development of a phased mine rescue drilling system (MRDS) that accomplishes (1) development of rapid drilling MRDS equipment; (2) structuring improved web communication through the Mine Safety & Health Administration (MSHA) web site; (3) development of an improved protocol for employment of existing drilling technology in emergencies; (4) deployment of advanced technologies to complement mine rescue drilling operations during emergency events; and (5) preliminary discussion of potential future technology development of specialized MRDS equipment. This phased approach allows for rapid fielding of a basic system for improved rescue drilling, with the ability to improve the system over time at a reasonable cost.

The actions taken at the initial times of a disaster are critical. Catastrophe occurs because of terrorist acts or natural hazards which have the potential to disrupt the infrastructure of wireless communication networks. Therefore, essential emergency functions such as search, rescue, and recovery operations during a catastrophic event will be disabled. We propose tethered balloon technology to provide efficient emergency communication services and reduce casualty mortality and morbidity for disaster recovery. The tethered balloon is an actively developed research area and a simple solution to support the performance, facilities, and services of emergency medical communication. The most critical requirement for rescue and relief teams is having a higher quality of communication services which enables them to save people's lives. Using our proposed technology, it has been reported that the performance of rescue and relief teams significantly improved. OPNET Modeler 14.5 is used for a network simulated with the help of ad hoc tools (Disaster Med Public Health Preparedness. 2018;page 1 of 8).

Decision making regarding cardiopulmonary resuscitation (CPR) is challenging. This study examined the effect of a video decision support tool on CPR preferences among patients with advanced cancer. We performed a randomized controlled trial of 150 patients with advanced cancer from four oncology centers. Participants in the control arm (n = 80) listened to a verbal narrative describing CPR and the likelihood of successful resuscitation. Participants in the intervention arm (n = 70) listened to the identical narrative and viewed a 3-minute video depicting a patient on a ventilator and CPR being performed on a simulated patient. The primary outcome was participants' preference for or against CPR measured immediately after exposure to either modality. Secondary outcomes were participants' knowledge of CPR (score range of 0 to 4, with higher score indicating more knowledge) and comfort with video. The mean age of participants was 62 years (standard deviation, 11 years); 49% were women, 44% were African American or Latino, and 47% had lung or colon cancer. After the verbal narrative, in the control arm, 38 participants (48%) wanted CPR, 41 (51%) wanted no CPR, and one (1%) was uncertain. In contrast, in the intervention arm, 14 participants (20%) wanted CPR, 55 (79%) wanted no CPR, and 1 (1%) was uncertain (unadjusted odds ratio, 3.5; 95% CI, 1.7 to 7.2; P advanced cancer who viewed a video of CPR were less likely to opt for CPR than those who listened to a verbal narrative.

Full Text Available Background. Basic life support (BLS training with hands-on practice can improve performance during simulated cardiac arrest, although the optimal duration for BLS training is unknown. This study aimed to assess the effectiveness of various BLS training durations for acquiring cardiopulmonary resuscitation (CPR and automated external defibrillator (AED skills. Methods. We randomised 485 South Korean nonmedical college students into four levels of BLS training: level 1 (40 min, level 2 (80 min, level 3 (120 min, and level 4 (180 min. Before and after each level, the participants completed questionnaires regarding their willingness to perform CPR and use AEDs, and their psychomotor skills for CPR and AED use were assessed using a manikin with Skill-Reporter™ software. Results. There were no significant differences between levels 1 and 2, although levels 3 and 4 exhibited significant differences in the proportion of overall adequate chest compressions (p<0.001 and average chest compression depth (p=0.003. All levels exhibited a greater posttest willingness to perform CPR and use AEDs (all, p<0.001. Conclusions. Brief BLS training provided a moderate level of skill for performing CPR and using AEDs. However, high-quality skills for CPR required longer and hands-on training, particularly hands-on training with AEDs.

IEDA (Integrated Earth Data Applications, www.iedadata.org), the NSF facility that operates EarthChem, the Marine Geoscience Data System, and the System for Earth Sample Registration, launched a Data Rescue Initiative in 2013 to advance preservation and re-use of valuable legacy datasets that are in danger of being lost. As part of this initiative, IEDA established a competition for Data Rescue Mini-Awards that provide modest funds to investigators to properly compile, document, and transfer legacy data sets to IEDA. Applications from late-career and near-retirement investigators were specifically encouraged. Awardees were given approximately six months to complete their data rescue activities. Three projects were awarded in 2013: (1) Geochemistry of Lunar Glasses: assembly of major element, trace element, volatile element, and isotope ratio data for lunar volcanic glasses and lunar impact glasses, (2) Geochemical and Geochronological data from Fiji, Izu-Bonin-Marianas, and Endeavor segment: assembly of published and unpublished data and metadata from large rock sample collections, and (3) Near-bottom Magnetic Data: curation and archival of 35 years of high-resolution, near-bottom magnetic field data from deeptowed platforms, submersibles, and ROVs. IEDA is working closely with the awardees to guide and support the data rescue effort and to assist with specific challenges related to outdated storage media or technology, diversity of platforms over decades of research, and the lack of established standards for data documentation. In this contribution we describe procedures and tools used for each project, summarize lessons learned and best practices, and present the final output of each data rescue project. Depending on the experiences of this first year and the availability of funds, we plan to continue the competition in future years.

BACKGROUND: Acute kidney injury (AKI) after cardiac surgery is common and is associated with increased mortality. We wanted to investigate if the arterial pressure or the use of norepinephrine during cardiopulmonary bypass were associated with AKI. METHODS: A retrospective analysis of patients who...... underwent coronary artery bypass grafting with or without concomitant procedures was conducted. AKI was defined using the RIFLE criteria. Data on arterial pressure and use of norepinephrine during cardiopulmonary bypass were entered in a binary logistic regression model to control for possible perioperative...... and in higher amounts, during cardiopulmonary bypass, in patients who developed AKI. These differences in arterial pressures and use of norepinephrine between the groups were not found to be significant when entered in the binary logistic regression model. CONCLUSION: No independent relationship between...

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

Constraints on decision making regarding post-commencement finance in Business rescue

Directory of Open Access Journals (Sweden)

Marius Pretorius

2013-12-01

Full Text Available Since its introduction, business rescue has become a critical consideration in business strategy decision making. One of the critical components of business rescue, which appears largely unsuccessful to date, involves securing post-commencement finance (PCF to restore the company’s financial health. Despite extensive theory in the literature on failure, there is a void regarding post-commencement finance. Specialist practitioners and financiers with extensive experience in rescue and turnaround were interviewed in this study. Findings showed that many critical factors and reasons for lack of interest are due to the newness of the South African Companies Act 71 of 2008 (introduced May 2011. These include business rescue filing being left too late; the poor financial state of the business that files for rescue; and the significant impact on the outcome by some of the key players (especially the financiers and business rescue practitioners. Better understanding of this aspect would be beneficial for creditors, rescue practitioners, shareholders, government regulators, court officials and educators alike.

To assess the effectiveness of femoral and radial arterial lines on the correlation of peripheral and central mean arterial blood pressure in children after discontinuation of cardiopulmonary bypass. Fifty children scheduled for cardiac surgery with cardiopulmonary bypass were included in the study. After approval from the hospital ethics committee and informed consent. 50 children undergoing cardiac surgical procedures with cardiopulmonary bypass were randomly assigned to two different groups. In Group- A (RAP, n-2) a radial arterial line and in Group-B (FAP, n-25) a femoral arterial line was used to monitor the blood pressure. Simultaneous mean peripheral arterial pressure and mean central aortic pressure were recorded before cardiopulmonary bypass and 5 mins after separation from the cardiopulmonary bypass. The correlation of mean peripheral arterial pressure (radial and femoral) versus mean aortic pressure were compared. The data was recorded as Mean +- SD and P-value. The ages of children ranged from 4-12 years and their weight from 14.1-28.5 kg. In all of them following cardiopulmonary bypass, aortic pressure correlates better with femoral arterial pressure (p<0.001). The radial arterial line readings under estimated central aortic pressure when compared to femoral arterial line readings. Aortic pressure readings correlate better with femoral arterial pressure than radial arterial pressure in children. (author)

2002-05-01

We sought to determine whether pretreatment with a sodium/hydrogen-exchange inhibitor (EMD 96 785) improves myocardial performance and reduces myocardial edema after cardioplegic arrest and cardiopulmonary bypass. Anesthetized dogs (n = 13) were instrumented with vascular catheters, myocardial ultrasonic crystals, and left ventricular micromanometers to measure preload recruitable stroke work, maximum rate of pressure rise (positive and negative), and left ventricular end-diastolic volume and pressure. Cardiac output was measured by means of thermodilution. Myocardial tissue water content was determined from sequential biopsy. After baseline measurements, hypothermic (28 degrees C) cardiopulmonary bypass was initiated. Cardioplegic arrest (4 degrees C Bretschneider crystalloid cardioplegic solution) was maintained for 2 hours, followed by reperfusion-rewarming and separation from cardiopulmonary bypass. Preload recruitable stroke work and myocardial tissue water content were measured at 30, 60, and 120 minutes after bypass. EMD 96 785 (3 mg/kg) was given 15 minutes before bypass, and 2 micromol was given in the cardioplegic solution. Control animals received the same volume of saline vehicle. Arterial-coronary sinus lactate difference was similar in both animals receiving EMD 96 785 and control animals, suggesting equivalent myocardial ischemia in each group. Myocardial tissue water content increased from baseline in both animals receiving EMD 96 785 and control animals with cardiopulmonary bypass and cardioplegic arrest but was statistically lower in animals receiving EMD 96 785 compared with control animals (range, 1.0%-1.5% lower in animals receiving EMD 96 785). Preload recruitable stroke work decreased from baseline (97 +/- 2 mm Hg) at 30 (59 +/- 6 mm Hg) and 60 (72 +/- 9 mm Hg) minutes after cardiopulmonary bypass and cardioplegic arrest in control animals; preload recruitable stroke work did not decrease from baseline (98 +/- 2 mm Hg) in animals receiving

A concept for optimizing avalanche rescue strategies using a Monte Carlo simulation approach.

Directory of Open Access Journals (Sweden)

Ingrid Reiweger

Full Text Available Recent technical and strategical developments have increased the survival chances for avalanche victims. Still hundreds of people, primarily recreationists, get caught and buried by snow avalanches every year. About 100 die each year in the European Alps-and many more worldwide. Refining concepts for avalanche rescue means to optimize the procedures such that the survival chances are maximized in order to save the greatest possible number of lives. Avalanche rescue includes several parameters related to terrain, natural hazards, the people affected by the event, the rescuers, and the applied search and rescue equipment. The numerous parameters and their complex interaction make it unrealistic for a rescuer to take, in the urgency of the situation, the best possible decisions without clearly structured, easily applicable decision support systems. In order to analyse which measures lead to the best possible survival outcome in the complex environment of an avalanche accident, we present a numerical approach, namely a Monte Carlo simulation. We demonstrate the application of Monte Carlo simulations for two typical, yet tricky questions in avalanche rescue: (1 calculating how deep one should probe in the first passage of a probe line depending on search area, and (2 determining for how long resuscitation should be performed on a specific patient while others are still buried. In both cases, we demonstrate that optimized strategies can be calculated with the Monte Carlo method, provided that the necessary input data are available. Our Monte Carlo simulations also suggest that with a strict focus on the "greatest good for the greatest number", today's rescue strategies can be further optimized in the best interest of patients involved in an avalanche accident.

Full Text Available Objective: To verify the presence and evaluate the levels of burnout syndrome in nurses of the prehospital rescue team. Methods: A cross-sectional study with a sample of 17 nurses from the prehospital rescue team, by application of the Maslach burnout Inventory and a questionnaire prepared by the authors. Rresults: In the group studied, 76% of the nurses of the prehospital rescue team were female. Ages varied from 30 to 49 years old. As to time already in the profession, 59% reported having worked from five to ten years in prehospital rescue. As to Maslach burnout Inventory subscale means, in the group analyzed of 17 prehospital rescue team nurses, low/moderate level (31.53 of reduced professional accomplishment, low/moderate level (18.41 of emotional exhaustion, and low/moderate level (8.88 of depersonalization were observed. As to dimensions of burnout levels, it was noted that 76.47% of the nurses displayed a low/moderate level of emotional exhaustion, depersonalization, and reduced professional accomplishment. Cconclusions: It was demonstrated that this sample showed no evidence of burnout syndrome, since its presence is proven only when there are high scores of emotional exhaustion, depersonalization, and reduced professional accomplishment.

Although multiple airway management and ventilation strategies have been proposed during cardiac arrest, the ideal strategy is unknown. Current strategies call for advanced airways, such as endotracheal intubation and supraglottic airways. These may facilitate hyperventilation which is known to adversely affect cardiopulmonary physiology. We provide a summary of conceptual models linking hyperventilation to patient outcomes and identify methods for mitigating hyperventilation during cardiac arrest. Copyright © 2015 Elsevier Inc.

2013-09-06

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

Paediatric cardiopulmonary arrest (CPA) survival rates are strongly linked to the training of the doctors responding to the event. This study sought to characterise the level of experience in managing CPAs among paediatric trainees and to investigate the nontechnical (NTS) required to effectively lead a paediatric CPA team. A mixed-methods research design was used. For the quantitative phase, a questionnaire was developed to assess training, confidence, and experiences related to CPA management. During the qualitative phase, 17 paediatric trainees participated in a series of critical incident technique (CIT) interviews to explore the NTS used during the management of paediatric CPAs. A total of 56 of 131 (37.1% response rate) trainees responded to the preparedness questionnaire. A total of 48.2% of respondents expressed low confidence in their skill as a team leader during the management of a CPA. The CIT interviews highlighted deficiencies in specific NTS (identifying options, prioritising, and identifying and utilising resources). Our results indicate that there is a desire for more training in CPA management among paediatric trainees, in particular as a team leader, which includes a focus on key NTS. What is Known • Levels of preparedness to be a paediatric cardiopulmonary arrests team member/leader are generally lower than desirable. • The importance of nontechnical skills to the effective performance of adult cardiopulmonary arrests teams has been identified. What is New • Levels of preparedness to be a cardiopulmonary arrests team member were higher than reported in US studies. • There is a need for greater training in cardiopulmonary arrest management which includes a focus on key nontechnical skills to include identifying options, prioritising, identifying and utilising resources.

Posture manipulation for rescue activity via small traction robots

Iwano, Yuki; Osuka, Koichi; Amano, Hisanori

2006-01-01

We discuss a conceptual design of rescue robots against nuclear-power plant accidents. We claim that the rescue robots in nuclear-power plants should have the following properties. (1) The size is small. (2) The structure is simple. (3) The number of the robots is large. This paper studies the rescue robots to rescue people in an area polluted with radioactive leakage in nuclear power institutions. In particular, we propose a rescue system which consists of a group of small mobile robots. First, small traction robots set the posture of the fainted victims to carry easily, and carry them to the safety space with the mobile robots for the stretcher composition. In this paper, we describe the produced small traction robots. And, we confirm that the robots can manipulate a 40 kg dummy doll's posture. We also examine the optimal number of robots from a perspective of working efficiency in the assumption spot. (author)

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

Rescue Effects: Irradiated Cells Helped by Unirradiated Bystander Cells

The rescue effect describes the phenomenon where irradiated cells or organisms derive benefits from the feedback signals sent from the bystander unirradiated cells or organisms. An example of the benefit is the mitigation of radiation-induced DNA damages in the irradiated cells. The rescue effect can compromise the efficacy of radioimmunotherapy (RIT) (and actually all radiotherapy). In this paper, the discovery and subsequent confirmation studies on the rescue effect were reviewed. The mechanisms and the chemical messengers responsible for the rescue effect studied to date were summarized. The rescue effect between irradiated and bystander unirradiated zebrafish embryos in vivo sharing the same medium was also described. In the discussion section, the mechanism proposed for the rescue effect involving activation of the nuclear factor κB (NF-κB) pathway was scrutinized. This mechanism could explain the promotion of cellular survival and correct repair of DNA damage, dependence on cyclic adenosine monophosphate (cAMP) and modulation of intracellular reactive oxygen species (ROS) level in irradiated cells. Exploitation of the NF-κB pathway to improve the effectiveness of RIT was proposed. Finally, the possibility of using zebrafish embryos as the model to study the efficacy of RIT in treating solid tumors was also discussed. PMID:25625514

REM sleep rescues learning from interference

2015-01-01

Classical human memory studies investigating the acquisition of temporally-linked events have found that the memories for two events will interfere with each other and cause forgetting (i.e., interference; Wixted, 2004). Importantly, sleep helps consolidate memories and protect them from subsequent interference (Ellenbogen, Hulbert, Stickgold, Dinges, & Thompson-Schill, 2006). We asked whether sleep can also repair memories that have already been damaged by interference. Using a perceptual learning paradigm, we induced interference either before or after a consolidation period. We varied brain states during consolidation by comparing active wake, quiet wake, and naps with either non-rapid eye movement sleep (NREM), or both NREM and REM sleep. When interference occurred after consolidation, sleep and wake both produced learning. However, interference prior to consolidation impaired memory, with retroactive interference showing more disruption than proactive interference. Sleep rescued learning damaged by interference. Critically, only naps that contained REM sleep were able to rescue learning that was highly disrupted by retroactive interference. Furthermore, the magnitude of rescued learning was correlated with the amount of REM sleep. We demonstrate the first evidence of a process by which the brain can rescue and consolidate memories damaged by interference, and that this process requires REM sleep. We explain these results within a theoretical model that considers how interference during encoding interacts with consolidation processes to predict which memories are retained or lost.

2017-12-01

The recent calls to rescue scientific data is a real opportunity to collaborate with federal agencies which have been spending years managing research data and making it secure. The 2013 memos from the White House Office of Science and Technology Policy and Office of Management and Budget have spurred innovation across federal agencies to make publicly funded data accessible. Now is the time for stakeholders to take advantage of the groundwork laid by federal government, support the work to expand data sharing, thereby encouraging open science.

The Triiodothyronine Supplementation in Infants and Children Undergoing Cardiopulmonary Bypass (TRICC) study demonstrated a shortened time to extubation in children younger than 5 months old undergoing cardiopulmonary bypass for congenital heart surgery with triiodothyronine supplementation. Cardiopulmonary bypass precipitates a systemic inflammatory response that affects recovery, and triiodothyronine is related to cytokine mediators of inflammation. We sought to investigate the preoperative cytokine levels by age and relationship to the triiodothyronine levels and to examine the effect of the cytokine levels on the time to extubation. We measured 6 cytokines at preoperative time 0 and 6 and 24 hours after crossclamp removal in 76 subjects. The preoperative cytokine levels were related to both the triiodothyronine levels and the patient age. The postoperative cytokine levels were predictive of the triiodothyronine levels at 6, 12, 24, and 72 hours. Preoperative CCL4 was associated with an increased chance of early extubation. Inclusion of the cytokines did not change the relationship of triiodothyronine to the time to extubation, and the postoperative course of interleukin-6 was independently associated with a decreased chance of early extubation. The preoperative and postoperative cytokine levels, in particular, interleukin-1β, showed complex time-dependent relationships with triiodothyronine. The data suggest that cytokine-mediated suppression of triiodothyronine plays an important role in determining the clinical outcome after cardiopulmonary bypass.

2014-10-01

The feasibility of symptom-limited cardiopulmonary exercise testing (CPET) prior to allo-SCT was assessed in addition to the prognostic value of CPET-derived measures. CPET was performed prospectively on 21 patients with hematologic malignancies, with assessments of peak (for example, peak oxygen consumption, VO2peak) and submaximal (for example, ventilatory threshold (VT)) measures of cardiopulmonary function. No serious adverse events were observed during CPET procedures, with 95% of patients achieving criteria for a peak test. Mean VO2peak was 24.7±6.4 mL kg(-1 )min(-1) (range: 10.9-35.5), equivalent to 29%±17% below that of age-matched healthy controls. All patients proceeded with the conditioning regimen followed by allo-SCT. Median follow-up was 25 months. During this period, 11 (52.4%) patients died (n=6, relapsed disease; n=5, non-relapse mortality (NRM)); 9 patients (43%) developed pulmonary toxicity. In univariate analyses, both peak and submaximal markers of cardiopulmonary function were predictors of OS, pulmonary toxicity and NRM. For OS, the HR for VO2peak and VT were 0.89 (95% CI, 0.8-0.99, P=0.04) and 0.84 (95% CI, 0.71-0.98, P=0.03), respectively. In conclusion, CPET is safe and feasible prior to allo-SCT. Patients have marked impairments in cardiopulmonary function prior to allo-SCT. CPET-derived metrics may complement conventional measures to improve risk stratification.

A simple technique can reduce cardiopulmonary bypass use during lung transplantation

Directory of Open Access Journals (Sweden)

Marcos N. Samano

2016-04-01

Full Text Available Cardiopulmonary bypass causes an inflammatory response and consumption of coagulation factors, increasing the risk of bleeding and neurological and renal complications. Its use during lung transplantation may be due to pulmonary hypertension or associated cardiac defects or just for better exposure of the pulmonary hilum. We describe a simple technique, or open pericardium retraction, to improve hilar exposure by lifting the heart by upward retraction of the pericardial sac. This technique permits lung transplantation without cardiopulmonary bypass when bypass use is recommended only for better exposure.

2018-03-01

Full Text Available The helicopter, as a means of transport, has facilitated a significant decrease in intervention time at the site of request, increasing the chances of survival of the critical patient. Since 2003, SMURD has managed to form a fleet composed of nine helicopters and two airplanes. From an operational and strategic point of view, the SMURD intervention unit, set up seven Aeromedical Operational Bases (A.O.B. equipped with helicopters and materials necessary for their operation. There is a dynamic increase in the number of air rescue missions in Romania, with most missions being carried out by the air rescue bases in Târgu Mureş and Bucharest. Specialty literature has clearly demonstrated the positive impact on the survival of critical patients assisted by airborne crews, so it is necessary for the Romanian air rescue system to grow up. It is necessary to increase the number of air bases, purchase new helicopters and to continue the training programs of both pilots and medical personnel.

2015-01-01

BACKGROUND: The quality of chest compressions can be significantly improved after training of rescuers according to the latest national guidelines of China. However, rescuers may be unable to maintain adequate compression or ventilation throughout a response of average emergency medical services because of increased rescuer fatigue. In the present study, we evaluated the performance of cardiopulmonary resuscitation (CPR) in training of military medical university students during a prolonged basic life support (BLS). METHODS: A 3-hour BLS training was given to 120 military medical university students. Six months after the training, 115 students performed single rescuer BLS on a manikin for 8 minutes. The qualities of chest compressions as well as ventilations were assessed. RESULTS: The average compression depth and rate were 53.7±5.3 mm and 135.1±15.7 compressions per minute respectively. The proportion of chest compressions with appropriate depth was 71.7%±28.4%. The average ventilation volume was 847.2±260.4 mL and the proportion of students with adequate ventilation was 63.5%. Compared with male students, significantly lower compression depth (46.7±4.8 vs. 54.6±4.8 mm, PCPR was found to be related to gender, body weight, and body mass index of students in this study. The quality of chest compressions was well maintained in male students during 8 minutes of conventional CPR but declined rapidly in female students after 2 minutes according to the latest national guidelines. Physical fitness and rescuer fatigue did not affect the quality of ventilation. PMID:26401177

2003-09-01

Intraoperative autologous blood withdrawal protects the pooled blood from the deleterious effects of cardiopulmonary bypass. Following reinfusion after cardiopulmonary bypass, the fresh autologous blood contributes to less coagulation abnormalities and reduces postoperative bleeding and the need for allogeneic blood products. However, few data have been available concerning the quality and potential activation of fresh blood stored at room temperature in the operating room. Forty coronary artery bypass grafting patients undergoing a consistent intraoperative and postoperative autotransfusion protocol had a median of 1,000 mL of autologous blood withdrawn before cardiopulmonary bypass. After heparinization the blood was drained from the venous catheter via venous cannula into standard blood bags and stored in the operating room until termination of cardiopulmonary bypass. Samples for hemostatic and inflammatory markers were taken from the pooled blood immediately before it was returned to the patient. There was some activation of platelets in the stored autologous blood, as measured by an increase of beta-thromboglobulin. Indications of thrombin formation, as assessed by plasma levels of thrombin-antithrombin complex and prothrombin fragment 1.2 were not seen, and there was no fibrinolytic activity. The red blood cells remained intact, indicated by the absence of plasma free hemoglobin. As for the inflammatory response, the levels of the terminal complement complex remained stable, and the cytokines tumor necrosis factor-alpha and interleukin 6 levels were not increased during storage. The complement activation products increased minimally, but remained within normal ranges. Except for slight activation of platelets, there was no indication of coagulation, hemolysis, fibrinolysis, or immunologic activity in the autologous blood after approximately 1 hour of operating room storage. The autologous blood was preserved in a condition of high quality, and retransfusion

Home continuous positive airway pressure for cardiopulmonary indications in infants and children.

Al-Iede, Montaha; Kumaran, Radhagini; Waters, Karen

2018-04-30

A number of reports exist regarding the use of continuous positive airway pressure (CPAP) to manage obstructive sleep apnoea (OSA) in children, which we term 'conventional CPAP'. In contrast, there are few reports of home CPAP use for other indications, which we have grouped under the term 'cardiopulmonary'. The aims of this study were to (1) document cardiopulmonary indications for CPAP use in a cohort of infants and children, and (2) evaluate its effectiveness in this group. Hospital records were reviewed for 645 patients who were commenced on long-term CPAP over a 10-year period at a single-tertiary hospital (Children's Hospital at Westmead). This study evaluated the group where the primary indication for CPAP was not OSA ('cardiopulmonary CPAP'). Data evaluated included: demographics, diagnoses, indications for CPAP, hours of use (compliance) and sleep study results at baseline and on CPAP. Of 645 children, 148 (23%) used home CPAP for cardiopulmonary indications; and 130 (87.8%) of these were included. For this group, mean age at CPAP initiation was 18.6 ± 33.6 months (range one week to 16.8 years). Cardiopulmonary indications for CPAP use included: primary airway diseases 65 (50%), chronic lung diseases 33 (25.4%), congenital heart disease (CHD) 20 (15.4%), and both CHD and airway malacia 12 (9.2%). All sleep study variables improved on CPAP relative to the diagnostic sleep study (p 4 h/night). Interstitial lung diseases and other cardiorespiratory disorders, often of congenital origin, can be effectively treated with home CPAP whether they are associated with OSA or not. Sleep studies demonstrated improved gas exchange, sleep and reduced work of breathing with CPAP use. Copyright © 2018 Elsevier B.V. All rights reserved.

Full Text Available Background. In the last fifteen years on the European continent and also worldwide, the prevalence of cardiopulmonary metastrongyloidosis in dogs and cats has increased significantly, especially cases involving those parasites which are the most important for veterinary practice (Angiostrongylus vasorum, Aelurostrongylus abstrusus and Crenosoma vulpis. Scope and Approach. The aim of this study is to present a detailed clinical-parasitological approach to highlight the importance of these helminths, and to display the newest findings concerning the diagnostic possibilities in dogs and cats Key Findings and Conclusions. The effects of global warming, vector range shift, the frequent transportation and movement of animals to other epizootic areas, as well as the intensification of merchandise transportation and movement of people are just some of the potential factors which could impact the dynamics of incidence, upkeep and spread of cardiopulmonary nematodoses in carnivores. For the timely implementation of effective treatment of sick animals, it essential to accurately diagnose these parasitoses. Accurate, timely diagnosis can, in the end, significantly contribute to the prognostic course of disease in infected carnivores. Cardiopulmonary metastrongyloidoses in dogs and cats have great clinical-parasitological significance because of their high degree of pathogenicity, their spread outside endemic areas, the difficulties encountered in establishing their diagnosis, and the fact that they represent a potential danger to human health.

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

2017-04-01

To evaluate intratracheal milrinone (tMil) administration for rapid treatment of right ventricular (RV) dysfunction as a novel route after cardiopulmonary bypass. Retrospective analysis. Single-center study. The study comprised 7 patients undergoing cardiac surgery who exhibited acute RV dysfunction after cardiopulmonary bypass. After difficult weaning caused by cardiopulmonary bypass-induced acute RV dysfunction, milrinone was administered as a 5-mg bolus inside the endotracheal tube. RV function improvement, as indicated by decreasing pulmonary artery pressure and changes of RV waveforms, was observed in all 7 patients. Adverse effects of tMil included dynamic RV outflow tract obstruction (2 patients) and a decrease in systemic mean arterial pressure (1 patient). tMil may be an effective, rapid, and easily applicable therapeutic alternative to inhaled milrinone for the treatment of acute RV failure during cardiac surgery. However, sufficiently powered clinical trials are needed to confirm these findings. Copyright © 2017 Elsevier Inc. All rights reserved.

1997-01-01

Radioimmunotherapy (RIT) is a promising treatment approach for B-cell lymphomas. This is our first opportunity to report long-term follow-up data and late toxicities in 29 patients treated with myeloablative doses of iodine-131-anti-CD20 antibody (anti-B1) and autologous stem-cell rescue. PATIENTS AND METHODS: Trace-labeled biodistribution studies first determined the ability to deliver higher absorbed radiation doses to tumor sites than to lung, liver, or kidney at varying amounts of anti-B1 protein (0.35, 1.7, or 7 mg/kg). Twenty- nine patients received therapeutic infusions of single-agent (131)I- anti-B1, given at the protein dose found optimal in the biodistribution study, labeled with amounts of (131)I (280 to 785 mCi[10.4 to 29.0 GBq]) calculated to deliver specific absorbed radiation doses to the normal organs, followed by autologous stem-cell support. RESULTS: Major responses occurred in 25 patients (86%), with 23 complete responses (CRs; 79%). The nonhematopoietic do se-limiting toxicity was reversible cardiopulmonary insufficiency, which occurred in two patients at RIT doses that delivered > or = 27 Gy to the lungs. With a median follow-up time of 42 months, the estimated overall and progression-free survival rates are 68% and 42%, respectively. Currently, 14 of 29 patients remain in unmaintained remissions that range from 27+ to 87+ months after RIT. Late toxicities have been uncommon except for elevated thyroid-stimulating hormone (TSH) levels found in approximately 60% of the subjects. Two patients developed second malignancies, but none have developed myelodysplasia (MDS). CONCLUSION: Myeloablative (131)I-anti- B1 RIT is relatively well tolerated when given with autologous stem- cell support and often results in prolonged remission durations with few late toxicities

CO{sub 2} in underground openings and mine rescue training

Energy Technology Data Exchange (ETDEWEB)

Weyer, J. [Freiburg Univ. of Mining and Technology (Germany). Inst. of Mining Engineering and Special Civil Engineering

2010-07-01

Mine rescue training procedures related to dangerous gases in mines were discussed. Methods of detecting carbon dioxide (CO{sub 2}) in abandoned opening and old adits were presented. High concentrations of CO{sub 2} combine with hemoglobin and lead to a lack of oxygen supply to the inner organs. Nitric acid forms in the alveoli and can lead to injuries or death after a period of 4 to 12 hours. Exposure to very high concentrations of CO{sub 2} can cause people to immediately lose consciousness. CO{sub 2} concentrations in the blood can change pH blood values. Members of mine rescue teams should be equipped with breathing equipment and be between 18 and 40 years old. Training rescue operations should be conducted 4 times per year. While larger mines have their own rescue teams, smaller mines must ensure that guest rescue teams are familiar with their mines. Various mine training activities were reviewed. 5 refs.

2011-01-01

Aim: To prospectively assess the cardiopulmonary morbidity and quality of life in patients with non-small cell lung cancer (NSCLC) treated with postoperative radiotherapy (PORT) in comparison to those not receiving PORT. Materials and methods: From 2003 to 2007, 291 patients entered the study; 171 pN2 patients received 3D-planned PORT (PORT group), 120 pN1 patients (non-PORT group) did not. One month after surgery, all patients completed EORTC QLQ C-30 questionnaire and had pulmonary function tests (PFT); cardiopulmonary symptoms were assessed by modified LENT-SOM scale. Two years later, disease-free patients repeated the same examinations. The differences between baseline values and values recorded at two years in QLQ, LENT-SOM and the PFT of the two groups were compared. Results: In the whole cohort, the rate of non-cancer related deaths was 5.3% and 5.0% in PORT and non-PORT group, respectively. Ninety-five patients (47 - PORT group, 48 - non-PORT group) were included into the final analysis. The differences in the QLQ and cardiopulmonary function (LENT/SOM, PFT) between both groups were insignificant. The forced expiratory volume in one second was on average 12.2% and 1.3% better in the PORT and the non-PORT group, respectively, p = 0.2. Conclusions: Our findings support the hypothesis about insignificant morbidity of 3D-planned PORT.

Reliable Rescue Routing Optimization for Urban Emergency Logistics under Travel Time Uncertainty

Qiuping Li

2018-02-01

Full Text Available The reliability of rescue routes is critical for urban emergency logistics during disasters. However, studies on reliable rescue routing under stochastic networks are still rare. This paper proposes a multiobjective rescue routing model for urban emergency logistics under travel time reliability. A hybrid metaheuristic integrating ant colony optimization (ACO and tabu search (TS was designed to solve the model. An experiment optimizing rescue routing plans under a real urban storm event, was carried out to validate the proposed model. The experimental results showed how our approach can improve rescue efficiency with high travel time reliability.

The rule of rescue.

Science.gov (United States)

McKie, John; Richardson, Jeff

2003-06-01

Jonsen coined the term "Rule of Rescue"(RR) to describe the imperative people feel to rescue identifiable individuals facing avoidable death. In this paper we attempt to draw a more detailed picture of the RR, identifying its conflict with cost-effectiveness analysis, the preference it entails for identifiable over statistical lives, the shock-horror response it elicits, the preference it entails for lifesaving over non-lifesaving measures, its extension to non-life-threatening conditions, and whether it is motivated by duty or sympathy. We also consider the measurement problems it raises, and argue that quantifying the RR would probably require a two-stage procedure. In the first stage the size of the individual utility gain from a health intervention would be assessed using a technique such as the Standard Gamble or the Time Trade-Off, and in the second the social benefits arising from the RR would be quantified employing the Person Trade-Off. We also consider the normative status of the RR. We argue that it can be defended from a utilitarian point of view, on the ground that rescues increase well-being by reinforcing people's belief that they live in a community that places great value upon life. However, utilitarianism has long been criticised for failing to take sufficient account of fairness, and the case is no different here: fairness requires that we do not discriminate between individuals on morally irrelevant grounds, whereas being "identifiable" does not seem to be a morally relevant ground for discrimination.

OBJECTIVE: To determine whether near infrared spectroscopic measurement of tissue pH and Po2 has sufficient accuracy to assess variation in tissue perfusion resulting from changes in blood pressure and metabolic demand during cardiopulmonary bypass. DESIGN: Prospective clinical study. SETTING: Academic medical center. SUBJECTS: Eighteen elective cardiac surgical patients. INTERVENTION: Cardiac surgery under cardiopulmonary bypass. MEASUREMENTS AND MAIN RESULTS: A near infrared spectroscopic fiber optic probe was placed over the hypothenar eminence. Reference Po2 and pH sensors were inserted in the abductor digiti minimi (V). Data were collected every 30 secs during surgery and for 6 hrs following cardiopulmonary bypass. Calibration equations developed from one third of the data were used with the remaining data to investigate sensitivity of the near infrared spectroscopic measurement to physiologic changes resulting from cardiopulmonary bypass. Near infrared spectroscopic and reference pH and Po2 measurements were compared for each subject using standard error of prediction. Near infrared spectroscopic pH and Po2 at baseline were compared with values during cardiopulmonary bypass just before rewarming commenced (hypotensive, hypothermic), after rewarming (hypotensive, normothermic) just before discontinuation of cardiopulmonary bypass, and at 6 hrs following cardiopulmonary bypass (normotensive, normothermic) using mixed-model analysis of variance. Near infrared spectroscopic pH and Po2 were well correlated with the invasive measurement of pH (R2 =.84) and Po2 (R 2 =.66) with an average standard error of prediction of 0.022 +/- 0.008 pH units and 6 +/- 3 mm Hg, respectively. The average difference between the invasive and near infrared spectroscopic measurement was near zero for both the pH and Po2 measurements. Near infrared spectroscopic Po2 significantly decreased 50% on initiation of cardiopulmonary bypass and remained depressed throughout the bypass and

Full Text Available In this paper, we optimize the search and rescue (SAR in disaster relief through agent-based simulation. We simulate rescue teams’ search behaviors with the improved Truncated Lévy walks. Then we propose a cooperative rescue plan based on a distributed auction mechanism, and illustrate it with the case of landslide disaster relief. The simulation is conducted in three scenarios, including “fatal”, “serious” and “normal”. Compared with the non-cooperative rescue plan, the proposed rescue plan in this paper would increase victims’ relative survival probability by 7–15%, increase the ratio of survivors getting rescued by 5.3–12.9%, and decrease the average elapsed time for one site getting rescued by 16.6–21.6%. The robustness analysis shows that search radius can affect the rescue efficiency significantly, while the scope of cooperation cannot. The sensitivity analysis shows that the two parameters, the time limit for completing rescue operations in one buried site and the maximum turning angle for next step, both have a great influence on rescue efficiency, and there exists optimal value for both of them in view of rescue efficiency.

Launch-Off-Need Shuttle Hubble Rescue Mission: Medical Issues

The Space Shuttle Hubble repair mission (STS-125) is unique in that a rescue mission (STS-400) has to be ready to launch before STS-125 life support runs out should the vehicle become stranded. The shuttle uses electrical power derived from fuel cells that use cryogenic oxygen and hydrogen (CRYO) to run all subsystems including the Environmental Control System. If the STS-125 crew cannot return to Earth due to failure of a critical subsystem, they must power down all nonessential systems and wait to be rescued by STS-400. This power down will cause the cabin temperature to be 60 F or less and freeze the rest of the vehicle, preventing it from attempting a reentry. After an emergency has been declared, STS-125 must wait at least 7 days to power down since that is the earliest that STS-400 can be launched. Problem The delayed power down of STS-125 causes CYRO to be consumed at high rates and limits the survival time after STS-400 launches to 10 days or less. CRYO will run out sooner every day that the STS-400 launch is delayed (weather at launch, technical issues etc.). To preserve CRYO and lithium hydroxide (LiOH - carbon dioxide removal) the crew will perform no exercise to reduce their metabolic rates, yet each deconditioned STS-125 crewmember must perform an EVA to rescue himself. The cabin may be cold for 10 days, which may cause shivering, increasing the metabolic rate of the STS-125 crew. Solution To preserve LiOH, the STS-125 manifest includes nutrition bars with low carbohydrate content to maintain crew respiratory quotient (RQ) below 0.85 as opposed to the usual shuttle galley food which is rich in carbohydrates and keeps the RQ at approximately 0.95. To keep the crew more comfortable in the cold vehicle warm clothing also has been included. However, with no exercise and limited diet, the deconditioned STS-125 crew returning on STS-400 may not be able to egress the vehicle autonomously requiring a supplemented crash-and-rescue capability.

Polycystic ovary syndrome (PCOS) is one of the most common reproductive disorder in premenopausal women and is frequently accompanied by the presence of cardiovascular risk factors. It has also been recognized that PCOS women are characterized by cardiopulmonary impairment. Reduced cardiopulmonary functional capacity and the autonomic dysfunction associated with abnormal heart rate recovery might be responsible for the increased cardiovascular risk in patients with PCOS. Exercise training has beneficial effects on cardiopulmonary functional capacity and reduces the risk of cardiovascular disease in PCOS women.

To determine the effect of Japanese obligatory basic life support training for new driver's license applicants on their willingness to carry out basic life support. We distributed a questionnaire to 9,807 participants of basic life support courses in authorized driving schools from May 2007 to April 2008 after the release of the 2006 Japanese guidelines. The questionnaire explored the participants' willingness to perform basic life support in four hypothetical scenarios: cardiopulmonary resuscitation on one's own initiative; compression-only cardiopulmonary resuscitation following telephone cardiopulmonary resuscitation; early emergency call; and use of an automated external defibrillator. The questionnaire was given at the beginning of the basic life support course in the first 6-month term and at the end in the second 6-month term. The 9,011 fully completed answer sheets were analyzed. The training significantly increased the proportion of respondents willing to use an automated external defibrillator and to perform cardiopulmonary resuscitation on their own initiative in those with and without prior basic life support training experience. It significantly increased the proportion of respondents willing to carry out favorable actions in all four scenarios. In multiple logistic regression analysis, basic life support training and prior training experiences within 3 years were associated with the attitude. The analysis of reasons for unwillingness suggested that the training reduced the lack of confidence in their skill but did not attenuate the lack of confidence in detection of arrest or clinical judgment to initiate a basic life support action. Obligatory basic life support training should be carried out periodically and modified to ensure that participants gain confidence in judging and detecting cardiac arrest.

Due to medical advances, most children with congenital heart disease (CHD) are expected to survive into adulthood. Establishing adequate physical self-concept and cardiopulmonary tolerance during the adolescent period can primarily enhance overall well-being. The purpose of this study was to undertake a gender-specific evaluation of the domain of physical self-concept among adolescents with mild CHD, and to examine the relationships between physical self-concept and cardiopulmonary exercise tolerance among adolescents with mild CHD. Four hundred and thirteen adolescents 12-20 years of age, whose cardiologists had not recommended any limitation of exercise, completed Physical Self-Description Questionnaires and three-minute step tests in two outpatient cardiology departments. The male participants had significantly greater scores in measures of overall physical self-concept, competence in sports, physical appearance, body fat, physical activity, endurance, and strength than did the female participants. More than 80% of the participants had at least an average cardiopulmonary exercise tolerance index. The perception of not being 'too fat' and being more physically active were significant correlates of better cardiopulmonary exercise tolerance for adolescents with mild CHD. The results provided evidence for gender-specific evaluation of domains of physical self-concept among adolescents with mild CHD. The three-minute step test to measure cardiopulmonary exercise tolerance in adolescents with mild CHD may be an appropriate objective measure for use in future research. Continued efforts are needed in early intervention to promote cardiopulmonary exercise tolerance. © The European Society of Cardiology 2014.

Inadequate cerebral oxygen balance during cardiopulmonary bypass may cause neuropsychological dysfunction. Milrinone, a phosphodiesterase III inhibitor, augments cerebral blood flow by direct vasodilatation. We conducted a prospective, randomized study in patients undergoing cardiac surgery with cardiopulmonary bypass to clarify the clinical efficacy of milrinone in the imbalance of cerebral oxygen supply and demand during the rewarming period of cardiopulmonary bypass. This is a prospective, randomized and placebo-controlled study. After anesthesia, a 5.5 F fiberoptic oximeter catheter was inserted into the right jugular bulb retrogradely for monitoring the jugular venous oxyhemoglobin saturation (SjO(2)). Patients were randomly assigned to two groups, one receiving a continuous infusion of milrinone, 0.5 µg/kg/min during hypothermic cardiopulmonary bypass, and the other receiving saline as control. Milrinone significantly prevented the reduction of the jugular venous oxyhemoglobin saturation at 10 minutes from the start of rewarming compared with the control group, but did not do so from 10 to 20 minutes after rewarming. Milrinone suppresses the reduction of SjO(2) and improves the balance of cerebral oxygen supply and demand during the early rewarming period of hypothermic cardiopulmonary bypass.

Microtubule catastrophe and rescue.

Science.gov (United States)

Gardner, Melissa K; Zanic, Marija; Howard, Jonathon

2013-02-01

Microtubules are long cylindrical polymers composed of tubulin subunits. In cells, microtubules play an essential role in architecture and motility. For example, microtubules give shape to cells, serve as intracellular transport tracks, and act as key elements in important cellular structures such as axonemes and mitotic spindles. To accomplish these varied functions, networks of microtubules in cells are very dynamic, continuously remodeling through stochastic length fluctuations at the ends of individual microtubules. The dynamic behavior at the end of an individual microtubule is termed 'dynamic instability'. This behavior manifests itself by periods of persistent microtubule growth interrupted by occasional switching to rapid shrinkage (called microtubule 'catastrophe'), and then by switching back from shrinkage to growth (called microtubule 'rescue'). In this review, we summarize recent findings which provide new insights into the mechanisms of microtubule catastrophe and rescue, and discuss the impact of these findings in regards to the role of microtubule dynamics inside of cells.

A study was conducted to the relationship between long-term exposure to fine particulate air pollution and all-cause, lung cancer, and cardiopulmonary mortality. Vital status and cause of death data were collected by the American Cancer Society as part of the Cancer Prevention II study, an ongoing prospective mortality study, which enrolled approximately 1.2 million adults in 1982. Participants completed a questionnaire detailing individual risk factor data (age, sex, race, weight, height, smoking history, education, marital status, diet, alcohol consumption, and occupational exposures). The risk factor data for approximately 500 000 adults were linked with air pollution data for metropolitan areas throughout the United States and combined with vital status and cause of death data through December 31, 1998. Fine particulate and sulfur oxide-related pollution were found to be associated with all-cause, lung cancer, and cardiopulmonary mortality. Each 10-{mu}g/m{sup 3} elevation in fine particulate air pollution was associated with approximately a 4%, 6%, and 8% increased risk of all-cause, cardiopulmonary, and lung cancer mortality, respectively. Measures of coarse particle fraction and total suspended particles were not consistently associated with mortality. It was concluded that long-term exposure to combustion-related fine particulate air pollution is an important environmental risk factor for cardiopulmonary and lung cancer mortality. 31 refs., 5 figs., 2 tabs.

During the European refugee crisis, numerous Greek and international rescue workers are operating in Lesvos, offering search, rescue, and first aid services. Exposure to stressful life events while engaging in this rescue work can result in developing Post-Traumatic Stress Disorder (PTSD). The study aimed to assess the prevalence of PTSD and explore potential differences between different categories of rescuers. A cross-sectional study was conducted among 217 rescue workers. Participants were grouped according to affiliation: "Greek Professionals Rescuers/GPR", "International Professionals Rescuers/IPR" and "Volunteer Rescuers/VR". The PTSD Checklist-Civilian Version (PCL-C) was utilized. All tests were two-tailed (a = 0.05). Mann-Whitney, Kruskal-Wallis, and multivariate logistic regression were performed. Overall probable PTSD prevalence found was 17.1%. Rates varied significantly per rescuer's category; 23.1% in GPR, 11.8% in IPR, and 14.6% in VR (p = 0.02). GPR demonstrated the highest risk compared to IPR and VR (p hours, and handling dead refugees and dead children were also considered major risk factors. Rescue workers providing substantial aid to the refugees and migrants at Lesvos experience significant psychological distress. The present findings indicate the urgent need for targeted interventions. Further studies are needed to address long-term effects of the refugee crisis on rescuers, and explore effective measures to prevent PTSD.

In patients with severe cardiomyopathy, recurrent episodes of nontolerated ventricular tachycardia (VT) or electrical storm (ES) frequently cause acute heart failure and cardiac death; the suppression of the arrhythmia is therefore lifesaving, but feasibility of catheter ablation (CA) is precluded by the adverse hemodynamic conditions together with the characteristics of the arrhythmia that interdicts efficacious mapping. The use of the percutaneous cardiopulmonary support (CPS) for circulatory assistance may allow patient's stabilization and enhance efficacy and safety of CA in this emergency setting. 19 patients (19 males; mean age 61 +/- 6 years; chronic ischemic cardiomyopathy, eleven patients; primary dilated cardiomyopathy, six patients; arrhythmogenic right ventricular dysplasia/ cardiomyopathy, two patients) with recurrent nontolerated VT episodes undergoing CPS-assisted CA were retrospectively evaluated. Twelve patients had acute hemodynamic failure refractory to inotropic agents and ventilatory assistance, seven patients had undergone a failing nonconventional CA procedure. 14 patients presented with ES, and in twelve the procedure was undertaken under emergency conditions within 24 h from admission. Patients were ventilated under general anesthesia and assisted by a multidisciplinary team. The CPS system consisted in a Medtronic Bio-Medicus centrifugal pump and in a Maxima Plus oxygenator, a 15-F arterial cannula, and a 17-F venous cannula. Flows between 2 and 3 l/min were activated after induction of 56/62 forms of nontolerated VT, achieving hemodynamic stabilization in all patients. CA was mainly guided by conventional activation mapping and was effective in abolishing 45/56 supported VTs; in 10/19 patients all clinical VTs were suppressed by CA. Mean procedural time was 4 h and 20 min. Complete stabilization was achieved in 13 patients (68%) without VT recurrence during a 7-day in-hospital monitoring. A significant clinical improvement was observed in

Undesirable detachment or stretching of coils within the parent artery during aneurysm embolization can be related with thrombus formation, which can be caused occlusion of parent artery or embolic event(s). To escape from this situation, several rescue methods have been reported. A case with undesirably stretched coil in which another rescue method was used, is presented. When the stretched coil is still located in the coil delivery microcatheter, the stretched coil can be removed safely using a snare and a handmade monorail microcatheter. After a snare is lodged in the handmade monorail microcatheter, the snare is introduced over the coil delivery micorcatheter and located in the distal part of the stretched coil. After then, the handmade monorail microcatheter captures the stretched coil and the snare as one unit. This technique using a handmade monorail microcatheter and a snare can be a good rescue modality for the undesirably stretched coil, still remained within the coil delivery microcatheter.

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

Flash flood swift water rescues, Texas, 2005–2014

Full Text Available Although rainfall patterns are complex and difficult to predict, climate models suggest precipitation in Texas will occur less frequently and with greater intensity in the future. In combination with rapid population growth and development, extreme rainfall events are likely to lead to flash floods and necessitate swift water rescues. Swift water rescues are used to retrieve person(s from swift water flowing at a rate of 1 knot or greater. Data were obtained from the Texas Fire Marshal’s Office and analyzed to describe spatial and temporal characteristics of rescues. Between 2005 and 2014, 3256 swift water rescues were reported from 136 of 254 (54% counties. Over half (54.6%, n = 1777 occurred in counties known as Flash Flood Alley, which includes Texas’ largest and fastest growing cities. Less than 1.0% (n = 18 were reported from 49 counties designated as completely rural, or with an urban population less than 2500. Increases in swift water rescues were seen between March and September and during major weather events such as tropical storms. Because county-level data was utilized and demographic data was missing in all but 2% (n = 47 of the incidents, our ability to identify populations at risk or target interventions in the future using this data is limited. Despite the frequency of flash flood events and swift water rescues in Texas, knowledge gaps persist that should be addressed through the conduct of interdisciplinary research by epidemiologists and climatologists and by disseminating evidence-based health education and safety programs, particularly in rapidly growing counties that make up Texas’ Flash Flood Alley.

Cardiopulmonary bypass in pregnancy.

Science.gov (United States)

Kapoor, Mukul Chandra

2014-01-01

Cardiac surgery carried out on cardiopulmonary bypass (CPB) in a pregnant woman is associated with poor neonatal outcomes although maternal outcomes are similar to cardiac surgery in non-pregnant women. Most adverse maternal and fetal outcomes from cardiac surgery during pregnancy are attributed to effects of CPB. The CPB is associated with utero-placental hypoperfusion due to a number of factors, which may translate into low fetal cardiac output, hypoxia and even death. Better maternal and fetal outcomes may be achieved by early pre-operative optimization of maternal cardiovascular status, use of perioperative fetal monitoring, optimization of CPB, delivery of a viable fetus before the operation and scheduling cardiac surgery on an elective basis during the second trimester.

Full Text Available This paper highlights the challenges the fire and rescue services can meet at façade fires involving EPS insulation during construction and use of a building. The EPS characteristics are discussed in respect to the fire and rescue operation and results from orientating fire tests performed at a fire and rescue services training and test field are presented. Types of evacuation solutions, involving the fire and rescue services, where façade fires can delay or completely rule out the possibilities for safe evacuation, are presented. The restrictions in the Swedish building codes regarding use of combustible insulation are analysed and reflections over the practical problems with following the instructions to keep an EPS insulated façade safe through the building's whole lifespan are made. A number of occurred fires involving EPS are discussed and analysed from a fire and rescue perspective. Finally, recommendations are given for the fire and rescue services and future research fields are proposed.

Vasoplegia syndrome, characterized by hypotension refractory to fluid resuscitation or high-dose vasopressors, low systemic vascular resistance, and normal-to-increased cardiac index, is associated with increased morbidity and mortality after cardiothoracic surgery. Methylene blue inhibits inducible nitric oxide synthase and guanylyl cyclase, and has been used to treat vasoplegia during cardiopulmonary bypass. However, because methylene blue is associated with increased pulmonary vascular resistance, its use in patients undergoing lung transplantion has been limited. Herein, we report the use of methylene blue to treat refractory vasoplegia during cardiopulmonary bypass in a patient undergoing double-lung transplantation.

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

Kahaly, G; Hellermann, J; Mohr-Kahaly, S; Treese, N

1996-01-01

Hyperthyroidism (H) has been implicated as a primary cause of decreased exercise tolerance. To our knowledge, analysis of respiratory gas exchange, an efficient noninvasive method in evaluating cardiopulmonary capacity, has not been performed in patients with H. Using cardiopulmonary exercise testing, 12 consecutive women with Graves' H were examined and controlled in euthyroidism (E). Eighteen women with E, in whom cardiac catheterization had ruled out heart disease, served as control subjects (C). The ventilatory anaerobic threshold was determined by means of the V-slope method. Ergometry was performed with patients in a semisupine position using a continuous ramp protocol of 20 W/min. Echocardiography at rest was performed in all patients. In patients with H, heart rate at rest was higher than in patients with E (p lower increase between rest and anaerobic threshold compared with E patients (p = 0.007) and C (p = 0.009). Work rate was reduced (H, 50% vs E, 70%; p = 0.038). In H patients, the anaerobic threshold occurred at 59.6% of maximal oxygen uptake and 72% in E patients, respectively (p = 0.024). In H patients, the linear regression of the heart rate to oxygen uptake ratio showed a reduced slope in comparison with E patients (p = 0.001) and C (p = 0.004). In patients with H, a reduced tidal volume (p = 0.021) and an increased respiratory rate (p = 0.003) in comparison to patients with E were demonstrated. Echocardiographically, H patients had an increased ejection fraction (p = 0.008) and a higher cardiac index (p = 0.008) in comparison with E patients. Analysis of respiratory gas exchange showed marked alterations of cardiopulmonary exercise capacity in H patients, which are reversible in E patients. The impaired chronotropic response during exercise might be the primary limiting factor of reduced work capacity in patients with H.

Effective communication between intensive care unit (ICU) providers and families is crucial given the complexity of decisions made regarding goals of therapy. Using video images to supplement medical discussions is an innovative process to standardize and improve communication. In this six-month, quasi-experimental, pre-post intervention study we investigated the impact of a cardiopulmonary resuscitation (CPR) video decision support tool upon knowledge about CPR among surrogate decision makers for critically ill adults. We interviewed surrogate decision makers for patients aged 50 and over, using a structured questionnaire that included a four-question CPR knowledge assessment similar to those used in previous studies. Surrogates in the post-intervention arm viewed a three-minute video decision support tool about CPR before completing the knowledge assessment and completed questions about perceived value of the video. We recruited 23 surrogates during the first three months (pre-intervention arm) and 27 surrogates during the latter three months of the study (post-intervention arm). Surrogates viewing the video had more knowledge about CPR (p=0.008); average scores were 2.0 (SD 1.1) and 2.9 (SD 1.2) (out of a total of 4) in pre-intervention and post-intervention arms. Surrogates who viewed the video were comfortable with its content (81% very) and 81% would recommend the video. CPR preferences for patients at the time of ICU discharge/death were distributed as follows: pre-intervention: full code 78%, DNR 22%; post-intervention: full code 59%, DNR 41% (p=0.23).

The quality of chest compressions can be significantly improved after training of rescuers according to the latest national guidelines of China. However, rescuers may be unable to maintain adequate compression or ventilation throughout a response of average emergency medical services because of increased rescuer fatigue. In the present study, we evaluated the performance of cardiopulmonary resuscitation (CPR) in training of military medical university students during a prolonged basic life support (BLS). A 3-hour BLS training was given to 120 military medical university students. Six months after the training, 115 students performed single rescuer BLS on a manikin for 8 minutes. The qualities of chest compressions as well as ventilations were assessed. The average compression depth and rate were 53.7±5.3 mm and 135.1±15.7 compressions per minute respectively. The proportion of chest compressions with appropriate depth was 71.7%±28.4%. The average ventilation volume was 847.2±260.4 mL and the proportion of students with adequate ventilation was 63.5%. Compared with male students, significantly lower compression depth (46.7±4.8 vs. 54.6±4.8 mm, P<0.001) and adequate compression rate (35.5%±26.5% vs. 76.1%±25.1%, P<0.001) were observed in female students. CPR was found to be related to gender, body weight, and body mass index of students in this study. The quality of chest compressions was well maintained in male students during 8 minutes of conventional CPR but declined rapidly in female students after 2 minutes according to the latest national guidelines. Physical fitness and rescuer fatigue did not affect the quality of ventilation.

Recently, hands only CPR (cardiopulmonary resuscitation) has been proposed as an alternative to standard CPR for bystanders. The present study was performed to identify the effect of basic life support (BLS) training on laypersons' willingness in performing standard CPR and hands only CPR. The participants for this study were non-medical personnel who applied for BLS training program that took place in 7 university hospitals in and around Korea for 6 months. Before and after BLS training, all the participants were given questionnaires for bystander CPR, and 890 respondents were included in the final analyses. Self-assessed confidence score for bystander CPR, using a visual analogue scale from 0 to 100, increased from 51.5+/-30.0 before BLS training to 87.0+/-13.7 after the training with statistical significance (p 0.001). Before the training, 19% of respondents reported willingness to perform standard CPR on a stranger, and 30.1% to perform hands only CPR. After the training, this increased to 56.7% of respondents reporting willingness to perform standard CPR, and 71.9%, hands only CPR, on strangers. Before and after BLS training, the odds ratio of willingness to perform hands only CPR versus standard CPR were 1.8 (95% CI 1.5-2.3) and 2.0 (95% CI 1.7-2.6) for a stranger, respectively. Most of the respondents, who reported they would decline to perform standard CPR, stated that fear of liability and fear of disease transmission were deciding factors after the BLS training. The BLS training increases laypersons' confidence and willingness to perform bystander CPR on a stranger. However, laypersons are more willing to perform hands only CPR rather than to perform standard CPR on a stranger regardless of the BLS training. Copyright 2010 Elsevier Ireland Ltd.

Full Text Available Subclinical hypothyroidism (SH patients present cardiopulmonary, vascular and muscle dysfunction, but there is no consensus about the benefits of levothyroxine (L-T4 intervention on cardiopulmonary performance during exercise. The aim of the present study was to investigate the effects of L-T4 on cardiopulmonary exercise reserve and recovery in SH patients. Twenty-three SH women, 44 (40-50 years old, were submitted to two ergospirometry tests, with an interval of 6 months of normalization of thyroid-stimulating hormone (TSH levels (L-T4 replacement group or simple observation (TSH = 6.90 μIU/mL; L-T4 = 1.02 ng/dL. Patients with TSH >10 μIU/mL were excluded from the study to assure that they would receive treatment in this later stage of SH. Twenty 30- to 57-year-old women with no thyroid dysfunction (TSH = 1.38 μIU/mL; L-T4 = 1.18 ng/dL were also evaluated. At baseline, lower values of gas exchange ratio reserve (0.24 vs 0.30; P < 0.05 were found for SH patients. The treated group presented greater variation than the untreated group for pulmonary ventilation reserve (20.45 to 21.60 L/min; median variation = 5.2 vs 25.09 to 22.45 L/min; median variation = -4.75, respectively and for gas exchange ratio reserve (0.19 to 0.27; median variation = 0.06 vs 0.28 to 0.18; median variation = -0.08, respectively. There were no relevant differences in cardiopulmonary recovery for either group at baseline or after follow-up. In the sample studied, L-T4 replacement improved exercise cardiopulmonary reserve, but no modification was found in recovery performance after exercise during this period of analysis.

High-quality cardiopulmonary resuscitation: current and future directions.

Science.gov (United States)

Abella, Benjamin S

2016-06-01

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

Patients with chronic heart failure (CHF) are characterized by abnormal gas exchange and ventilatory responses to exercise. This study compares variables obtained from cardiopulmonary exercise testing in 35 patients with CHF with 35 age- and weight-matched healthy subjects. A second goal was to obtain cardiopulmonary variables measured at ventilatory threshold to distinguish patient changes from those of healthy subjects. Exercise testing was carried out using bicycle ergometry with ramplike protocol (work rate increments 12.5 W/min). Gas exchange and ventilation were measured breath by breath. Compared with healthy subjects, the VO2 in patients was lower at identical work rates (p rate, the variables for VO2, VCO2, ventilation, O2 pulse, ventilatory equivalents for O2 and CO2, and VD/VT (physiologic deadspace to tidal volume ratio), as well as lactate differed significantly at identical work rates. With the exception of VD/VT, all cardiopulmonary variables showed significant differences in their slopes during exercise. By means of a discriminant analysis, VCO2 and ventilation proved to be the most distinguishing variables at ventilatory threshold between patients with CHF and healthy subjects. These results indicate the clinical usefulness of cardiopulmonary exercise testing when assessing functional impairment due to CHF. For treatment evaluation, not only VO2 but also VCO2 and ventilation responses to exercise should be considered.

Cardiopulmonary bypass in pregnancy

Mukul Chandra Kapoor

Full Text Available Cardiac surgery carried out on cardiopulmonary bypass (CPB in a pregnant woman is associated with poor neonatal outcomes although maternal outcomes are similar to cardiac surgery in non-pregnant women. Most adverse maternal and fetal outcomes from cardiac surgery during pregnancy are attributed to effects of CPB. The CPB is associated with utero-placental hypoperfusion due to a number of factors, which may translate into low fetal cardiac output, hypoxia and even death. Better maternal and fetal outcomes may be achieved by early pre-operative optimization of maternal cardiovascular status, use of perioperative fetal monitoring, optimization of CPB, delivery of a viable fetus before the operation and scheduling cardiac surgery on an elective basis during the second trimester.

The present study describes a method for the continuous determination of global and regional stress-induced alterations of cardiopulmonary blood volumes in normals, trained athletes and patients with latent cardiac insufficiency. In contrast to normals and athletes there is an increase of the total cardiac blood volume in the cardiac patients. There are also significant differences in blood volume changes of the left lung between normals and athletes on the one hand and the cardiac patients on the other. The method is simple and non-hazardous; it permits the observation of the obviously different adaptation of the cardiopulmonary system during exercise in normals, athletes and cardiac patients.

Scoliosis causes impairment of the respiratory and cardiovascular systems. Traditional pulmonary function tests only examine patients under static conditions. The aim of our study was to investigate the correlation between radiographic parameters and dynamic cardiopulmonary capacity in patients with idiopathic scoliosis. Forty patients with idiopathic scoliosis were included in this prospective study from January 2014 to February 2016. The patients underwent full radiographic assessment of deformity, pulmonary function testing, and cardiopulmonary bicycle ergometer testing. The impact of the severity of thoracic curvature and kyphosis on pulmonary function and physical capacity was investigated. Thirty-three female patients with a mean age of 15.5 years (range, 11 to 35 years) and coronal thoracic curvature of 49.4° (range, 24° to 76°) and 7 male subjects with a mean age of 15.9 years (range, 13 to 18 years) and coronal thoracic curvature of 47.1°(range, 22° to 80°) were included. No correlation was found between coronal thoracic curvature and pulmonary function test results in the female patients. Female patients with a thoracic curve of ≥60° had lower blood oxygen saturation at maximal exercise in the cardiopulmonary exercise test (p = 0.032). Female patients with a thoracic curve of ≥50° had a higher respiratory rate (p = 0.041) and ventilation volume per minute (p = 0.046) and lower breathing reserve at maximal exercise (p = 0.038). Thoracic kyphosis in female patients was positively correlated with pulmonary function, as shown by the forced expiratory volume in 1 second (r = 0.456, p = 0.01), forced vital capacity (r = 0.366, p = 0.043), vital capacity (r = 0.525, p = 0.006), and total lung capacity (r = 0.388, p = 0.031), as well as with tidal volume (r = 0.401, p = 0.025) in cardiopulmonary exercise testing. Female patients who engaged in regular exercise had better peak oxygen intake normalized by body weight (p rate (p = 0.020), and heart rate

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).

A Review of Mine Rescue Ensembles for Underground Coal Mining in the United States.

Science.gov (United States)

Kilinc, F Selcen; Monaghan, William D; Powell, Jeffrey B

The mining industry is among the top ten industries nationwide with high occupational injury and fatality rates, and mine rescue response may be considered one of the most hazardous activities in mining operations. In the aftermath of an underground mine fire, explosion or water inundation, specially equipped and trained teams have been sent underground to fight fires, rescue entrapped miners, test atmospheric conditions, investigate the causes of the disaster, or recover the dead. Special personal protective ensembles are used by the team members to improve the protection of rescuers against the hazards of mine rescue and recovery. Personal protective ensembles used by mine rescue teams consist of helmet, cap lamp, hood, gloves, protective clothing, boots, kneepads, facemask, breathing apparatus, belt, and suspenders. While improved technology such as wireless warning and communication systems, lifeline pulleys, and lighted vests have been developed for mine rescuers over the last 100 years, recent research in this area of personal protective ensembles has been minimal due to the trending of reduced exposure of rescue workers. In recent years, the exposure of mine rescue teams to hazardous situations has been changing. However, it is vital that members of the teams have the capability and proper protection to immediately respond to a wide range of hazardous situations. Currently, there are no minimum requirements, best practice documents, or nationally recognized consensus standards for protective clothing used by mine rescue teams in the United States (U.S.). The following review provides a summary of potential issues that can be addressed by rescue teams and industry to improve potential exposures to rescue team members should a disaster situation occur. However, the continued trending in the mining industry toward non-exposure to potential hazards for rescue workers should continue to be the primary goal. To assist in continuing this trend, the mining industry

Climate science as a whole as well as reanalyses as a special case can significantly profit from the recovery, imaging and digitisation of historical observations. The importance of this fact is reflected in large, global data rescue projects and initiatives such as the Atmospheric Circulation Reconstructions over the Earth (ACRE, www.met-acre.org) or the EU FP7 ERA-CLIM project (www.era-clim.eu). From the time before 1957, there are still large amounts of surface data e.g. from former colonies and from overseas territories of European countries )e.g. Portugal, France and Germany) that need to be rescued. Also in case of the very early upper-air observations before the 1930s, even Europe and North America still hold an important quantity of data to be recovered in digital form. Here, we present the web platform "Data Rescue @ Home" (www.data-rescue-at-home.org), which has been developed at ETH Zurich and Oeschger Centre for Climate Change Research, and which has been designed to take advantage of the voluntary assistance of the thousands of people on the web who are interested in climate or old weather data. On the website, these volunteers can enter meteorological data shown on digital images into entry masks that resemble the original. By registering, the users get access to their personal digitisation statistics and help optimising the project. At the moment, 4 digitisation projects are online: One project is dealing with German upper-air data from the Second World War period. In a second project, station data from Tulagi (Solomon Islands) is being digitised. Finally, two collaborative projects have been included: One in cooperation with the Instituto Dom Luiz (Univ. Lisbon, Portugal), where Portuguese station data from Angra (Azores) is digitised, and a further one in cooperation with the German Meteorological Service (DWD), in which precipitation data from former German colonies is being digitised. On our poster, we will report on the status of the projects

Capnography during cardiopulmonary resuscitation: Current evidence and future directions

Directory of Open Access Journals (Sweden)

Bhavani Shankar Kodali

2014-01-01

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.

Objective To investigate the effectiveness of brief bedside “booster” cardiopulmonary resuscitation (CPR) training to improve CPR guideline compliance of hospital-based pediatric providers. Design Prospective, randomized trial. Setting General pediatric wards at Children’s Hospital of Philadelphia. Subjects Sixty-nine Basic Life Support–certified hospital-based providers. Intervention CPR recording/feedback defibrillators were used to evaluate CPR quality during simulated pediatric arrest. After a 60-sec pretraining CPR evaluation, subjects were randomly assigned to one of three instructional/feedback methods to be used during CPR booster training sessions. All sessions (training/CPR manikin practice) were of equal duration (2 mins) and differed only in the method of corrective feedback given to participants during the session. The study arms were as follows: 1) instructor-only training; 2) automated defibrillator feedback only; and 3) instructor training combined with automated feedback. Measurements and Main Results Before instruction, 57% of the care providers performed compressions within guideline rate recommendations (rate >90 min−1 and 38 mm); and 36% met overall CPR compliance (rate and depth within targets). After instruction, guideline compliance improved (instructor-only training: rate 52% to 87% [p .01], and overall CPR compliance, 43% to 78% [p CPR compliance, 35% to 96% [p training combined with automated feedback: rate 48% to 100% [p CPR compliance, 30% to 100% [p CPR instruction, most certified Pediatric Basic Life Support providers did not perform guideline-compliant CPR. After a brief bedside training, CPR quality improved irrespective of training content (instructor vs. automated feedback). Future studies should investigate bedside training to improve CPR quality during actual pediatric cardiac arrests. PMID:20625336

Prior observational studies suggest no additional benefit from advanced life support (ALS) when compared with providing basic life support (BLS) for patients with out-of-hospital cardiac arrest (OHCA). We compared the association of ALS care with OHCA outcomes using prospective clinical data from the Resuscitation Outcomes Consortium (ROC). Included were consecutive adults OHCA treated by participating emergency medical services (EMS) agencies between June 1, 2011, and June 30, 2015. We defined BLS as receipt of cardiopulmonary resuscitation (CPR) and/or automated defibrillation and ALS as receipt of an advanced airway, manual defibrillation, or intravenous drug therapy. We compared outcomes among patients receiving: 1) BLS-only; 2) BLS + late ALS; 3) BLS + early ALS; and 4) ALS-first care. Using multivariable logistic regression, we evaluated the associations between level of care and return of spontaneous circulation (ROSC), survival to hospital discharge, and survival with good functional status, adjusting for age, sex, witnessed arrest, bystander CPR, shockable initial rhythm, public location, EMS response time, CPR quality, and ROC site. Among 35,065 patients with OHCA, characteristics were median age 68 years (IQR 56-80), male 63.9%, witnessed arrest 43.8%, bystander CPR 50.6%, and shockable initial rhythm 24.2%. Care delivered was: 4.0% BLS-only, 31.5% BLS + late ALS, 17.2% BLS + early ALS, and 47.3% ALS-first. ALS care with or without initial BLS care was independently associated with increased adjusted ROSC and survival to hospital discharge unless delivered greater than 6 min after BLS arrival (BLS + late ALS). Regardless of when it was delivered, ALS care was not associated with significantly greater functional outcome. ALS care was associated with survival to hospital discharge when provided initially or within six minutes of BLS arrival. ALS care, with or without initial BLS care, was associated with increased ROSC, however it was

The treatment of children with life-threatening cardiac and cardiopulmonary failure is a large and underappreciated public health concern. We have previously shown that the CentriMag is a magnetically levitated centrifugal pump system, having the utility for treating adults and large children (1,500 utilized worldwide). We present here the PediVAS, a pump system whose design was modified from the CentriMag to meet the physiological requirements of young pediatric and neonatal patients. The PediVAS is comprised of a single-use centrifugal blood pump, reusable motor, and console, and is suitable for right ventricular assist device (RVAD), left ventricular assist device (LVAD), biventricular assist device (BVAD), or extracorporeal membrane oxygenator (ECMO) applications. It is designed to operate without bearings, seals and valves, and without regions of blood stasis, friction, or wear. The PediVAS pump is compatible with the CentriMag hardware, although the priming volume was reduced from 31 to 14 ml, and the port size reduced from 3/8 to (1/4) in. For the expected range of pediatric flow (0.3-3.0 L/min), the PediVAS exhibited superior hydraulic efficiency compared with the CentriMag. The PediVAS was evaluated in 14 pediatric animals for up to 30 days, demonstrating acceptable hydraulic function and hemocompatibility. The current results substantiate the performance and biocompatibility of the PediVAS cardiac assist system and are likely to support initiation of a US clinical trial in the future.

2015-01-01

Abstract Early, high-quality cardiopulmonary resuscitation (CPR) is the key to increasing the likelihood of successful resuscitation in cardiac arrest. The use of dispatch-assisted (DA) CPR can increase the likelihood of bystander CPR. We describe a case in which a metronome was introduced to guide DA-CPR. The wife of a 52-year-old male activated 9-1-1 after her husband suffered a cardiac arrest. During her 9-1-1 call she received CPR instructions and heard a metronome over the phone while following the instructions. Return of spontaneous circulation of the patient occurred during paramedic on scene care. The patient was transported to hospital and discharged 6 days later with no neurological deficit. This case supports the use of a metronome by emergency medical dispatchers during the provision of DA-CPR to improve bystander CPR.

Objective: To constitute a normal standard of cardiopulmonary vascular diameter and size of normal adult in Lanzhou, and to compared with the other's data reported in the previous bibliography by measuring diameter and area of cardiopulmonary artery lumen of the healthy adults in Lanzhou with multislice spiral CT (MSCT). Methods: Three hundred Lanzhou adults with no cardiopulmonary disease were equally assigned to 3 groups according to their age (A group: 18-39 years, B group: 40-60 years, C group: 61-80 years; 50 females and 50 males in each group). CT data were acquired at the end of deep inspiration phase and measurements were done on 3D reconstruction image with precise landmarks. All the results were statistically analyzed. Results: The diameters and areas of the main pulmonary artery left pulmonary artery right pulmonary artery ascending aorta and descending aorta differed significantly among the 3 groups (P<0.05). In groups B and C, there were significant differences in diameters and areas of pulmonary artery left pulmonary artery and right pulmonary between different genders (P<0.05). Conclusion: Imaging standard is provided for Lanzhou adult in early diagnosis of cardiopulmonary disease. The diameters and areas of main pulmonary artery left pulmonary artery and right pulmonary artery of Lanzhou healthy adults are different from that of other regions. It may be related to the geographical environment and the state of air pollution in Lanzhou. (authors)

This study investigated strategies to improve sleeping conditions during search and rescue operations during disaster response. Forty members of the Montgomery County (Maryland) Urban Search and Rescue Team were surveyed for individual sleep habits and sleeping aids used during extended deployments. Team members were also asked to suggest methods to improve sleep on future deployments. The average amount of sleep during field operations was 5.4 hours with a range of 4-8 hours. Eight percent surveyed would prefer another schedule besides the 12-hour work day, all of whom proposed three 8-hour shifts. Fifteen percent of participants were interested in a pharmacological sleeping aid. Fifty percent of search and rescue members interviewed would consider using nonpharmacological sleeping aids. Furthermore, 40% of participants stated they had successfully devised self-employed methods of sleep aids for previous deployments, such as ear plugs, massage, mental imagery, personal routines, music and headphones, reading, and blindfolds. This study suggests that availability of both pharmacological and nonpharmacological sleeping aids to search and rescue workers via the team cache could impact the quantity of sleep. Further investigation into methods of optimizing sleep during field missions could theoretically show enhanced performance through various aspects of missions including mitigation of errors, improved productivity, and improved overall physiological and emotional well-being of search and rescue personnel.

Does modern helicopter construction reduce noise exposure in helicopter rescue operations?

Science.gov (United States)

Küpper, Thomas; Jansing, Paul; Schöffl, Volker; van Der Giet, Simone

2013-01-01

During helicopter rescue operations the medical personnel are at high risk for hearing damage by noise exposure. There are two important factors to be taken into account: first, the extreme variability, with some days involving no exposure but other days with extreme exposure; second, the extreme noise levels during work outside the helicopter, e.g. during winch operations. The benefit of modern, less noisier constructions and the consequences for noise protection are still unknown. We estimated the noise exposure of the personnel for different helicopter types used during rescue operations in the Alps and in other regions of the world with special regard to the advanced types like Eurocopter EC 135 to compare the benefit of modern constructions for noise protection with earlier ones. The rescue operations over 1 year of four rescue bases in the Alps (Raron and Zermatt in Switzerland; Landeck and Innsbruck in Austria, n = 2731) were analyzed for duration of rescue operations (noise exposure). Noise levels were measured during rescue operations at defined points inside and outside the different aircraft. The setting is according to the European standard (Richtlinie 2003/10/EG Amtsblatt) and to Class 1 DIN/IEC 651. With both data sets the equivalent noise level L(eq8h) was calculated. For comparison it was assumed that all rescue operations were performed with a specific type of helicopter. Then model calculations for noise exposure by different helicopter types, such as Alouette IIIb, Alouette II 'Lama', Ecureuil AS350, Bell UH1D, Eurocopter EC135, and others were performed. Depending on modern technologies the situation for the personnel has been improved significantly. Nevertheless noise prevention, which includes noise intermissions in spare time, is essential. Medical checks of the crews by occupational medicine (e.g. 'G20' in Germany) are still mandatory.

2001-09-15

The role of sirolimus (SRL) as a rescue agent (n=42) and as a component of primary immunosuppression (n=8) was evaluated in a mixed population of 50 transplanted children receiving tacrolimus (liver: 26, heart: 5, intestinal: 5, liver-intestine: 9, lung: 1, bone marrow: 1, liver-kidney: 1, multivisceral: 1). Rescue indications for tacrolimus (TAC) failure were recurrent acute rejection and acute rejection complicating withdrawal of immunosuppression in posttransplant lymphoproliferative disorder (PTLD). Rescue indications for TAC toxicity were nephrotoxicity, pancreatitis, seizures, hypertrophic cardiomyopathy, and graft-versus-host disease. Mean age at rescue was 11.5 years and mean follow-up was 204 (range 18-800) days. As primary immunosuppression, SRL+TAC prevented early acute rejection in 7/8 children. The indication for rescue resolved in 33/42 children. In children with TAC toxicity, this was associated with decrease in TAC doses by 50%, significant improvements in renal function, and continuing decline in Epstein-Barr virus (EBV) viral load in PTLD patients. Serious adverse events led to discontinuation of SRL in 9/42 rescue patients, 3 of them also experienced acute rejection. Three additional children also experienced acute rejection on SRL therapy (overall incidence 6/50, 12%). Pharmacokinetic analysis in the first week of SRL administration suggested a short half-life (11.8+/-5.5 hr, n=21). SRL and reduced-dose TAC may achieve adequate immunosuppression without compromising renal function or enhancing EBV viremia significantly.

Diabetes mellitus is a highly prevalent condition in patients participating in cardiopulmonary rehabilitation. However, research and subsequent guidelines specifically applicable to patients with diabetes, participating in cardiopulmonary rehabilitation, are limited. Recognizing this limitation, the American Association of Cardiovascular and Pulmonary Rehabilitation (AACVPR) initiated this statement, with the goal of developing a template that incorporated recommendations provided in the AACVPR Core Components and the American Association of Diabetes Educators 7 Self-Care Behaviors. This statement describes key processes regarding evaluation, interventions, and expected outcomes in each of the core components for the management of patients with diabetes in a cardiopulmonary rehabilitation program.

Full Text Available Abstract Background D-CPR (Defibrillator Cardiopulmonary Resuscitation is a technique for optimal basic life support during cardiopulmonary resuscitation (CPR. Guidelines recommend that healthcare professionals can perform CPR with competence. How CPR training and provision is organized varies between hospitals, and it is our impression that in Sweden this has generally improved during the last 15-20 years. However, some hospitals still do not have any AED (Automated External Defibrillators. The aim was to investigate potential differences in practical skills between different healthcare professions before and after training in D-CPR. Methods Seventy-four healthcare professionals were video recorded and evaluated for adherence to a modified Cardiff Score. A Laerdal Resusci Anne manikin in connection to PC Skill reporting System was used to evaluate CPR quality. A simulated CPR situation was accomplished during a 5-10 min scenario of ventricular fibrillation. Paired and unpaired statistical methods were used to examine differences within and between occupations with respect to the intervention. Results There were no differences in skills among the different healthcare professions, except for compressions per minute. In total, the number of compression per minute and depth improved for all groups (P P Conclusion Nearly all healthcare professionals learned to use the AED. There were no differences in CPR skill performances among the different healthcare professionals.

Lactate rescues neuronal sodium homeostasis during impaired energy metabolism.

Karus, Claudia; Ziemens, Daniel; Rose, Christine R

2015-01-01

Recently, we established that recurrent activity evokes network sodium oscillations in neurons and astrocytes in hippocampal tissue slices. Interestingly, metabolic integrity of astrocytes was essential for the neurons' capacity to maintain low sodium and to recover from sodium loads, indicating an intimate metabolic coupling between the 2 cell types. Here, we studied if lactate can support neuronal sodium homeostasis during impaired energy metabolism by analyzing whether glucose removal, pharmacological inhibition of glycolysis and/or addition of lactate affect cellular sodium regulation. Furthermore, we studied the effect of lactate on sodium regulation during recurrent network activity and upon inhibition of the glial Krebs cycle by sodium-fluoroacetate. Our results indicate that lactate is preferentially used by neurons. They demonstrate that lactate supports neuronal sodium homeostasis and rescues the effects of glial poisoning by sodium-fluoroacetate. Altogether, they are in line with the proposed transfer of lactate from astrocytes to neurons, the so-called astrocyte-neuron-lactate shuttle.

Genetic Information, the Principle of Rescue, and Special Obligations.

Liao, S Matthew; Mackenzie, Jordan

2018-05-01

In "Genetic Privacy, Disease Prevention, and the Principle of Rescue," Madison Kilbride argues that patients have a duty to warn biological family members about clinically actionable adverse genetic findings. The duty does not stem from the special obligations that we may have to family members, she argues, but rather follows from the principle of rescue, which she understands as the idea that one ought to prevent, reduce, or mitigate the risk of harm to another person when the expected harm is serious and the cost or risk to oneself is sufficiently moderate. We doubt, however, whether the principle of rescue can ground a duty to warn in the cases Kilbride envisages, and we suggest that Kilbride may have underappreciated the role that special obligations could play in generating a duty to warn family members. © 2018 The Hastings Center.

Rescue US: Birth, Django, and the Violence of Racial Redemption

Directory of Open Access Journals (Sweden)

Joseph Winters

2018-01-01

Full Text Available In this article, I show how the relationship between race, violence, and redemption is articulated and visualized through film. By juxtaposing DW Griffith’s The Birth of a Nation and Quentin Tarantino’s Django Unchained, I contend that the latter inverts the logic of the former. While Birth sacrifices black bodies and explains away anti-black violence for the sake of restoring white sovereignty (or rescuing the nation from threatening forms of blackness, Django adopts a rescue narrative in order to show the excessive violence that structured slavery and the emergence of the nation-state. As an immanent break within the rescue narrative, Tarantino’s film works to “rescue” images and sounds of anguish from forgetful versions of history.

Pan, Jun; Huang, Haiguang; Liu, Yousong

A novel data mart based system for fishery rescue field was designed and implemented. The system runs ETL process to deal with original data from various databases and data warehouses, and then reorganized the data into the fishery rescue data mart. Next, online analytical processing (OLAP) are carried out and statistical reports are generated automatically. Particularly, quick configuration schemes are designed to configure query dimensions and OLAP data sets. The configuration file will be transformed into statistic interfaces automatically through a wizard-style process. The system provides various forms of reporting files, including crystal reports, flash graphical reports, and two-dimensional data grids. In addition, a wizard style interface was designed to guide users customizing inquiry processes, making it possible for nontechnical staffs to access customized reports. Characterized by quick configuration, safeness and flexibility, the system has been successfully applied in city fishery rescue department.

Hypothermia and postconditioning after cardiopulmonary resuscitation reduce cardiac dysfunction by modulating inflammation, apoptosis and remodeling.

Directory of Open Access Journals (Sweden)

Patrick Meybohm

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

Surgical mortality increases significantly with age. Wide variations in mortality rates across hospitals suggest potential levers for improvement. Failure-to-rescue has been posited as a potential mechanism underlying these differences. A review was undertaken of the literature evaluating surgery, mortality, failure-to-rescue and the elderly. This was followed by a review of ongoing studies and unpublished work aiming to understand better the mechanisms underlying variations in surgical mortality in elderly patients. Multiple hospital macro-system factors, such as nurse staffing, available hospital technology and teaching status, are associated with differences in failure-to-rescue rates. There is emerging literature regarding important micro-system factors associated with failure-to-rescue. These are grouped into three broad categories: hospital resources, attitudes and behaviours. Ongoing work to produce interventions to reduce variations in failure-to-rescue rates include a focus on teamwork, communication and safety culture. Researchers are using novel mixed-methods approaches and theories adapted from organizational studies in high-reliability organizations in an effort to improve the care of elderly surgical patients. Although elderly surgical patients experience failure-to-rescue events at much higher rates than their younger counterparts, patient-level effects do not sufficiently explain these differences. Increased attention to the role of organizational dynamics in hospitals' ability to rescue these high-risk patients will establish high-yield interventions aimed at improving patient safety. © 2015 BJS Society Ltd Published by John Wiley & Sons Ltd.

Cardiovascular diseases are the most popular cause of death in the world recently. For postoperatives, cardiac rehabilitation is still asked to maintain at home (phase II) to improve cardiac function. However, only one third of outpatients do the exercise regularly, reflecting the difficulty for home-based healthcare: lacking of monitoring and motivation. Hence, a cardio-pulmonary rehabilitation system was proposed in this research to improve rehabilitation efficiency for better prognosis. The proposed system was built on mobile phone and receiving electrocardiograph (ECG) signal from a wireless ECG holter via Bluetooth connection. Apart from heart rate (HR) monitor, an ECG derived respiration (EDR) technique is also included to provide respiration rate (RR). Both HR and RR are the most important vital signs during exercise but only used one physiological signal recorder in this system. In clinical test, there were 15 subjects affording Bruce Task (treadmill) to simulate rehabilitation procedure. Correlation between this system and commercial product (Custo-Med) was up to 98% in HR and 81% in RR. Considering the prevention of sudden heart attack, an arrhythmia detection expert system and healthcare server at the backend were also integrated to this system for comprehensive cardio-pulmonary monitoring whenever and wherever doing the exercise.

Full Text Available The basic variants of cytokines reactions defining type of organ dysfunctions are revealed in the course of car- diopulmonary bypass and in the early postoperative period. Their character and expression, depends on gravity preoperative an immunodeficiency and initial degree of heart insufficiency. Diphasic dynamics of development of system inflammatory reaction is confirmed after cardiopulmonary bypass: increase of levels proinflammatory cytokines is in the first phase and anti-inflammatory cytokines with development immunodepression and cellular anergy in is the second phase. Also, key role IL-1Ra is revealed in restraint of hyperactivation of system inflam- matory reaction. Blood whey levels IL-6, IL-8, G-CSF, TNF-α and IL-1Ra should be defined to cardiopulmonary bypass, in 10–12 hours, 24 hours and 3 days after cardiopulmonary bypass and may be used as prognostic criteria of development of postoperative complications.

A 43-year-old woman became exhausted and fainted on descent at 1127 MAMSL altitude and snowfall. A rescue team diagnosed asystole. With manual cardiopulmonary resuscitation (CPR) she was transported to the next extracorporeal life support (ECLS) center. Admission temperature was 20.7 °C. CPR continued until ECLS was initiated. Two days later she was awake, orientated, and with no neurological deficits. With hypothermic cardiac arrest, a favorable outcome depends on early continuous CPR, triage, and ECLS rewarming. It holds true that "nobody is dead until they are warmed and dead" if one cools first and arrests thereafter.

Data Rescue Case Studies from the Cryosphere

Fetterer, F. M.

2017-12-01

A simple definition of the cryosphere is "where the world is frozen", or where water takes the form of snow and ice. The cryosphere is shrinking as the Earth warms. Data, particularly old data, document this in often eye-opening fashion. A photograph of Alaska's Muir Glacier taken in 1902 next to one taken in 2005 has impact that a line graph of air temperature anomalies from a weather station can't match, even though temperature data are fundamental to climate research and to understanding the glacier retreat captured in the photographs. Whaling logbooks from the late 1800s, maps of sea ice shared internationally in the 1930s, and satellite images of the polar oceans from the 1960s are not as immediately thought-provoking as are glacier photographs, but when preserved and documented they provide a record of sea ice coverage that is more than 100 years long. We developed a data product from these and other sources that is used in meteorological reanalysis and to answer questions about ice in the Arctic prior to 1978, when commonly used satellite-data-derived sea ice records begin. Preserving glacier photographs and making them available online, and publishing a gridded sea ice data product that builds on the preservation work of others are examples of data rescue projects that benefit scientific research and mobilize knowledge. These and other case studies suggest that even absent secure funding and an organizational setting that supports data rescue, important data make the transition from someone's office to archived and online with metadata because scientists are impassioned about the data they collect and want others to be able to use these data. In these cases from the cryosphere, student interns, collaborations with librarians, and cooperation with colleagues in other data centers have made it possible to preserve data at low cost.

Treating surgical complications presents a major challenge for hospitals striving to deliver high-quality care while reducing costs. Costs associated with rescuing patients from perioperative complications are poorly characterized. To evaluate differences across hospitals in the costs of care for patients surviving perioperative complications after major inpatient surgery. Retrospective cohort study using claims data from the Medicare Provider Analysis and Review files. We compared payments for patients who died vs patients who survived after perioperative complications occurred. Hospitals were stratified using average payments for patients who survived following complications, and payment components were analyzed across hospitals. Administrative claims database of surgical patients was analyzed at hospitals treating Medicare patients nationwide. This study included Medicare patients aged 65 to 100 years who underwent abdominal aortic aneurysm repair (n = 69 207), colectomy for cancer (n = 107 647), pulmonary resection (n = 91 758), and total hip replacement (n = 307 399) between 2009 and 2012. Data analysis took place between November 2015 and March 2016. Clinical outcome of surgery (eg, no complication, complication and death, or complication and survival) and the individual hospital where a patient received an operation. Risk-adjusted, price-standardized Medicare payments for an episode of surgery. Risk-adjusted perioperative outcomes were also assessed. The mean age for Medicare beneficiaries in this study ranged from 74.1 years (pulmonary resection) to 78.2 years (colectomy). The proportion of male patients ranged from 37% (total hip replacement) to 77% (abdominal aortic aneurysm repair), and most patients were white. Among patients who experienced complications, those who were rescued had higher price-standardized Medicare payments than did those who died for all 4 operations. Assessing variation across hospitals, payments for patients

Mechanical heart-lung interactions are often overlooked in clinical settings. However, their impact on cardiac function can be quite significant. Mechanistic physiology-based models can provide invaluable insights into such cardiorespiratory interactions, which occur not only under external mechanical ventilatory support but in normal physiology as well. In this work, we focus on the cardiac component of a previously developed mathematical model of the human cardiopulmonary system, aiming to improve the model's response to the intrathoracic pressure variations that are associated with the respiratory cycle. Interventricular septum and pericardial membrane are integrated into the existing model. Their effect on the overall cardiac response is explained by means of comparison against simulation results from the original model as well as experimental data from literature.

The aim of this study was to assess potential changes in the performance and cardiorespiratory responses of elite cross-country skiers following transition from the classic (CL) to the skating (SK) technique during a simulated skiathlon. Eight elite male skiers performed two 6 km (2 × 3 km) roller-skiing time trials on a treadmill at racing speed: one starting with the classic and switching to the skating technique (CL1-SK2) and another employing the skating technique throughout (SK1-SK2), with continuous monitoring of gas exchanges, heart rates, and kinematics (video). The overall performance times in the CL1-SK2 (21:12 ± 1:24) and SK1-SK2 (20:48 ± 2:00) trials were similar, and during the second section of each performance times and overall cardiopulmonary responses were also comparable. However, in comparison with SK1-SK2, the CL1-SK2 trial involved significantly higher increases in minute ventilation (V̇E, 89.8 ± 26.8 vs. 106.8 ± 17.6 L·min(-1)) and oxygen uptake (V̇O2; 3.1 ± 0.8 vs 3.5 ± 0.5 L·min(-1)) 2 min after the transition as well as longer time constants for V̇E, V̇O2, and heart rate during the first 3 min after the transition. This higher cardiopulmonary exertion was associated with ∼3% faster cycle rates. In conclusion, overall performance during the 2 time trials did not differ. The similar performance times during the second sections were achieved with comparable mean cardiopulmonary responses. However, the observation that during the initial 3-min post-transition following classic skiing cardiopulmonary responses and cycle rates were slightly higher supports the conclusion that an initial section of classic skiing exerts an impact on performance during a subsequent section of skate skiing.

Stranded marine mammals have long attracted public attention. Those that wash up dead are, for all their value to science, seldom seen by the public as more than curiosities. Animals that are sick, injured, orphaned or abandoned ignite a different response. Generally, public sentiment supports any effort to rescue, treat and return them to sea. Institutions displaying marine mammals showed an early interest in live-stranded animals as a source of specimens -- in 1948, Marine Studios in...

2016-01-01

Neurological impairments can limit the implementation of conventional cardiopulmonary exercise testing (CPET) and cardiovascular training strategies. A promising approach to provoke cardiovascular stress while facilitating task-specific exercise in people with disabilities is feedback-controlled robot-assisted end-effector-based stair climbing (RASC). The aim of this study was to evaluate the feasibility, reliability, and repeatability of augmented RASC-based CPET in able-bodied subjects, with a view towards future research and applications in neurologically impaired populations. Twenty able-bodied subjects performed a familiarisation session and 2 consecutive incremental CPETs using augmented RASC. Outcome measures focussed on standard cardiopulmonary performance parameters and on accuracy of work rate tracking (RMSEP-root mean square error). Criteria for feasibility were cardiopulmonary responsiveness and technical implementation. Relative and absolute test-retest reliability were assessed by intraclass correlation coefficients (ICC), standard error of the measurement (SEM), and minimal detectable change (MDC). Mean differences, limits of agreement, and coefficients of variation (CoV) were estimated to assess repeatability. All criteria for feasibility were achieved. Mean V'O2peak was 106±9% of predicted V'O2max and mean HRpeak was 99±3% of predicted HRmax. 95% of the subjects achieved at least 1 criterion for V'O2max, and the detection of the sub-maximal ventilatory thresholds was successful (ventilatory anaerobic threshold 100%, respiratory compensation point 90% of the subjects). Excellent reliability was found for peak cardiopulmonary outcome measures (ICC ≥ 0.890, SEM ≤ 0.60%, MDC ≤ 1.67%). Repeatability for the primary outcomes was good (CoV ≤ 0.12). RASC-based CPET with feedback-guided exercise intensity demonstrated comparable or higher peak cardiopulmonary performance variables relative to predicted values, achieved the criteria for V'O2max

Withholding or termination of resuscitation in pediatric out-of-hospital traumatic cardiopulmonary arrest.

Science.gov (United States)

Fallat, Mary E

2014-04-01

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

Filgrastim as a Rescue Therapy for Persistent Neutropenia in a Case of Dengue Hemorrhagic Fever with Acute Respiratory Distress Syndrome and Myocarditis

Full Text Available Pathogenesis of dengue involves suppression of immune system leading to development of characteristic presentation of haematological picture of thrombocytopenia and leucopenia. Sometimes, this suppression in immune response is responsible for deterioration in clinical status of the patient in spite of all specific and supportive therapy. Certain drugs like steroids are used for rescue therapy in conditions like sepsis. We present a novel use of filgrastim as a rescue therapy in a patient with dengue hemorrhagic fever (DHF with acute respiratory distress syndrome (ARDS, myocarditis, and febrile neutropenia and not responding to standard management.

Hyperglycemia after cardiac surgery and cardiopulmonary bypass in children has been associated with worse outcome; however, causality has never been proven. Furthermore, the benefit of tight glycemic control is inconsistent. The purpose of this study was to describe the metabolic constellation of children before, during, and after cardiopulmonary bypass, in order to identify a subset of patients that might benefit from insulin treatment. Prospective observational study, in which insulin treatment was initiated when postoperative blood glucose levels were more than 12 mmol/L (216 mg/dL). Tertiary PICU. Ninety-six patients 6 months to 16 years old undergoing cardiac surgery with cardiopulmonary bypass. None. Metabolic tests were performed before anesthesia, at the end of cardiopulmonary bypass, at PICU admission, and 4 and 12 hours after PICU admission, as well as 4 hours after initiation of insulin treatment. Ketosis was present in 17.9% patients at the end of cardiopulmonary bypass and in 31.2% at PICU admission. Young age was an independent risk factor for this condition. Ketosis at PICU admission was an independent risk factor for an increased difference between arterial and venous oxygen saturation. Four hours after admission (p = 0.05). Insulin corrected ketosis within 4 hours. In this study, we found a high prevalence of ketosis at PICU admission, especially in young children. This was independently associated with an imbalance between oxygen transport and consumption and was corrected by insulin. These results set the basis for future randomized controlled trials, to test whether this subgroup of patients might benefit from increased glucose intake and insulin during surgery to avoid ketosis, as improving oxygen transport and consumption might improve patient outcome.

Full Text Available Abstract Background To summarize the diagnostic and therapeutic experiences on the patients who suffered abdominal complications after cardiovascular surgery with cardiopulmonary bypass(CPB. Methods A total of 2349 consecutive patients submitted to cardiovascular surgery with CPB in our hospital from Jan 2004 to Dec 2010 were involved. The clinical data of any abdominal complication, including its incidence, characters, relative risks, diagnostic measures, medical or surgical management and mortality, was retrospectively analyzed. Results Of all the patients, 33(1.4% developed abdominal complications postoperatively, including 11(33.3% cases of paralytic ileus, 9(27.3% of gastrointestinal haemorrhage, 2(6.1% of gastroduodenal ulcer perforation, 2(6.1% of acute calculus cholecystitis, 3(9.1% of acute acalculus cholecystitis, 4(12.1% of hepatic dysfunction and 2(6.1% of ischemia bowel diseases. Of the 33 patients, 26 (78.8% accepted medical treatment and 7 (21.2% underwent subsequent surgical intervention. There were 5(15.2% deaths in this series, which was significantly higher than the overall mortality (2.7%. Positive history of peptic ulcer, advanced ages, bad heart function, preoperative IABP support, prolonged CPB time, low cardiac output and prolonged mechanical ventilation are the risk factors of abdominal complications. Conclusions Abdominal complications after cardiovascular surgery with CPB have a low incidence but a higher mortality. Early detection and prompt appropriate intervention are essential for the outcome of the patients.

To create a self-sufficient, innovative method for providing cardiopulmonary resuscitation (CPR) education within a college of pharmacy using a student-driven committee, and disseminating CPR education into the community through a service learning experience. A CPR committee comprised of doctor of pharmacy (PharmD) students at the University of Tennessee College of Pharmacy provided CPR certification to all pharmacy students. The committee developed a service learning project by providing CPR training courses in the community. Participants in the course were required to complete an evaluation form at the conclusion of each training course. The CPR committee successfully certified more than 1,950 PharmD students and 240 community members from 1996 to 2009. Evaluations completed by participants were favorable, with 99% of all respondents (n = 351) rating the training course as either "excellent" or "good" in each of the categories evaluated. A PharmD student-directed committee successfully provided CPR training to other students and community members as a service learning experience.

End-stage heart failure affects thousands of children yearly and mechanical circulatory support is used at many points in their care. Extracorporeal membrane oxygenation supports both the failing heart and lungs, which has led to its use as an adjunct to cardiopulmonary resuscitation as well as in post-operative cardiogenic shock. Continuous-flow ventricular assist devices (VAD) have replaced pulsatile-flow devices in adults and early studies have shown promising results in children. The Berlin paracorporeal pulsatile VAD recently gained U.S. Food and Drug Administration approval and remains the only VAD approved in pediatrics. Failing univentricular hearts and other congenitally corrected lesions are new areas for mechanical support. Finding novel uses, improving durability, and minimizing complications are areas of growth in pediatric mechanical circulatory support.

The objective of the conducted research is the identification and determination of requirements of members of fire rescue brigades during operations in the conditions of high risk in order to minimize the possibilities for injury incidence during the intervention. The research is focused on examination, determination and identification of factors affecting the increasing number of occupational injuries of members of fire rescue brigades during interventions. Hypothetical framework of the research problem consists of general hypothesis and six special hypotheses. Results suggest that almost all respondents believe that their skills and abilities are applicable in the intervention phase, but less than a half believe that their skills are applicable in prevention phase. Two-thirds of respondents stated that in their organization they have support for further education and upgrading while a half of respondents stated that they need education concerning identification, assessment and management of risks that can lead to emergency situations.

Dispatching Plan Based on Route Optimization Model Considering Random Wind for Aviation Emergency Rescue

Directory of Open Access Journals (Sweden)

Ming Zhang

2016-01-01

Full Text Available Aviation emergency rescue is an effective means of nature disaster relief that is widely used in many countries. The dispatching plan of aviation emergency rescue guarantees the efficient implementation of this relief measure. The conventional dispatching plan that does not consider random wind factors leads to a nonprecise quick-responsive scheme and serious safety issues. In this study, an aviation emergency rescue framework that considers the influence of random wind at flight trajectory is proposed. In this framework, the predicted wind information for a disaster area is updated by using unscented Kalman filtering technology. Then, considering the practical scheduling problem of aircraft emergency rescue at present, a multiobjective model is established in this study. An optimization model aimed at maximizing the relief supply satisfaction, rescue priority satisfaction, and minimizing total rescue flight distance is formulated. Finally, the transport times of aircraft with and without the influence of random wind are analyzed on the basis of the data of an earthquake disaster area. Results show that the proposed dispatching plan that considers the constraints of updated wind speed and direction is highly applicable in real operations.

Full Text Available Background and Aims: Nurses should have cardiopulmonary resuscitation (CPR knowledge and skills to be able to implement effective interventions during in-hospital cardiac arrest. The aim of this descriptive study was to assess mortality impact after nurses' CPR training with pre-CPR training data at our institute. Methods: Training regarding CPR was given to nurses, and CPR mortality 1-year before basic life support (BLS and advanced cardiac life support (ACLS training were collected and compared with post-training 1-year CPR mortality. Results: A total of 632 adult patients suffering in-hospital cardiac arrest over the study period. CPR was attempted in 294 patients during the pre-BLS/ACLS training period and in 338 patients in the post-BLS/ACLS training period. In the pre-BLS/ACLS training period, 58 patients (19.7% had return of spontaneous circulation (ROSC, while during the post-BLS/ACLS training period, 102 patients (30.1% had ROSC (P = 0.003. Sixteen of the 58 patients (27.5% who achieved ROSC during the pre-BLS/ACLS training period survived to hospital discharge, compared 54 out of 102 patients (52.9% in the post-BLS/ACLS training period (P < 0.0001. There was no significant association between either the age or sex with the outcomes in the study. Conclusion: Training nurses in cardiopulmonary resuscitation resulted in a significant improvement in survival to hospital discharge after in-hospital cardiac arrest.

Bystander cardiopulmonary resuscitation (CPR) is critical to the survival of patients with out-of-hospital cardiac arrest (OHCA). However, it is unknown whether bystander CPR with or without dispatcher assistance is more effective or why. Thus, we evaluated the association between dispatcher-assisted bystander CPR (vs. bystander CPR without dispatcher assistance) and survival of patients with OHCA. This is a retrospective, nonrandomized, observational study using national registry data for all OHCAs. We performed a propensity analysis. Patients with OHCA of cardiac origin were 18-100 years of age and received bystander chest compression in Japan between 2005 and 2014. Outcome measures were bystander rescue breathing, return of spontaneous circulation (ROSC) before hospital arrival, and survival and Cerebral Performance Category (CPC) 1 or 2 at 1 month after the event. During the study period, 1,176,351 OHCAs occurred, and 87,400 cases met the inclusion criteria. Among propensity-matched patients, a negative association was observed between dispatcher-assisted bystander CPR and outcome measures in a fully-adjusted model [odds ratio (OR) (95% CI) for ROSC = 0.87 (0.78-0.97), P < 0.05; OR (95% CI) for 1-month survival = 0.81 (0.65-1.00), P < 0.05; OR (95% CI) for CPC 1 or 2 = 0.64 (0.43-0.93), P < 0.05]. OR of survival for dispatcher-assisted bystander CPR tended to decrease as the emergency medical services response time increased. Survival benefit was less for dispatcher-assisted bystander CPR with dispatcher assistance than without dispatcher assistance. Low quality is hypothesized to be the cause of the reduced benefit.

A study on the data of the physique investigated in teenagers was carried out between Hong Kong and inland cities to compare their cardiopulmonary endurance and muscular fitness. Results revealed that cardiopulmonary endurance in school teenagers of both sex at different ages in inland cities was better than that in Hong Kong. Muscular strength and endurance of sports performance of teenagers, except for standing long jump, in Hong Kong were weaker than that in inland cities. It suggests that attention should be paid to the involvement of teenagers in physical education with the increase of people's living standard.

The goal(s of corporate rescue in company law: A comparative analysis

Full Text Available The concept of corporate rescue lays emphasis on corporate sustainability than liquidation. This trend in corporate legislation which featured in the United Kingdom Insolvency Act of 1986, Australian Corporations Act 2001, Indian Sick Industrial Companies (Special Provisions Act of 1985 (as replaced by Companies Act, 2013 and supplanted by the Insolvency and Bankruptcy Code, 2016 has been adopted in the South African Companies Act of 2008. The goal(s of corporate rescue in some of these jurisdictions are not clearly defined. The paper examines, through a comparative analysis, the relevant statutory provisions in the United Kingdom, India, Australia and South Africa and the attendant judicial interpretations of those provisions with a view to discovering the goal(s of corporate rescue in those jurisdictions. It is argued that while under the United Kingdom and Australian statutory provisions, the administrator could pursue alternative goals of either rescuing the company or achieving better results for the creditors; the South African and Indian statutory provisions do not provide such alternatives. The seeming ancillary purpose of crafting a fair deal for the stakeholders under the South African Companies Act’s provision is not sustainable if the company as an entity cannot be rescued

Poor quality cardiopulmonary resuscitation (CPR) predicts adverse outcome. During invasive cardiac procedures automated-CPR (A-CPR) may help maintain effective resuscitation. The use of A-CPR following in-hospital cardiac arrest (IHCA) remains poorly described. Firstly, we aimed to assess the efficiency of healthcare staff using A-CPR in a cardiac arrest scenario at baseline, following re-training and over time (Scenario-based training). Secondly, we studied our clinical experience of A-CPR at our institution over a 2-year period, with particular emphasis on the details of invasive cardiac procedures performed, problems encountered, resuscitation rates and in-hospital outcome (AutoPulse-CPR Registry). Scenario-based training: Forty healthcare professionals were assessed. At baseline, time-to-position device was slow (mean 59 (±24) s (range 15-96s)), with the majority (57%) unable to mode-switch. Following re-training time-to-position reduced (28 (±9) s, pCPR Registry: 285 patients suffered IHCA, 25 received A-CPR. Survival to hospital discharge following conventional CPR was 28/260 (11%) and 7/25 (28%) following A-CPR. A-CPR supported invasive procedures in 9 patients, 2 of whom had A-CPR dependant circulation during transfer to the catheter lab. A-CPR may provide excellent haemodynamic support and facilitate simultaneous invasive cardiac procedures. A significant learning curve exists when integrating A-CPR into clinical practice. Further studies are required to better define the role and effectiveness of A-CPR following IHCA. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Numerous series, propensity-matched trials, and meta-analyses suggest that appropriate use of extracorporeal cardiopulmonary resuscitation (E-CPR) for in-hospital cardiac arrest (IHCA) can be lifesaving. Even with an antecedent cardiopulmonary resuscitation (CPR) duration in excess of 45 minutes, 30-day survival with favourable neurologic outcome using E-CPR is approximately 35%-45%. Survival may be related to age, duration of CPR, or etiology. Associated complications include sepsis, renal failure, limb and neurologic complications, hemorrhage, and thrombosis. However, methodological biases-including small sample size, selection bias, publication bias, and inability to control for confounders-in these series prevent definitive conclusions. As such, the 2015 American Heart Association Advanced Cardiac Life Support guidelines update recommended E-CPR as a Level of Evidence IIb recommendation in appropriate cases. The absence of high-quality evidence presents an opportunity for clinician/scientists to generate practice-defining data through collaborative investigation and prospective trials. A multidisciplinary dialogue is required to standardize the field and promote multicentre investigation of E-CPR with data sharing and the development of a foundation for high-quality trials. The objectives of this review are to (1) provide an overview of the strengths and limitations of currently available studies investigating the use of E-CPR in patients with IHCA and highlight knowledge gaps; (2) create a framework for the standardization of terminology, clinical practice, data collection, and investigation of E-CPR for patients with IHCA that will help ensure congruence in future work in this area; and (3) propose suggestions to guide future research by the cardiovascular community to advance this important field.

Duchenne muscular dystrophy (DMD) is a neuromuscular disease that predominantly affects boys as a result of mutation(s) in the dystrophin gene. DMD is characterized by musculoskeletal and cardiopulmonary complications, resulting in shorter life-span. Boys afflicted by DMD typically exhibit symptoms within 3-5 years of age and declining physical functions before attaining puberty. We hypothesized that rapidly deteriorating health of pre-pubertal boys with DMD could be due to diminished anabolic actions of androgens in muscle, and that intervention with an androgen receptor (AR) agonist will reverse musculoskeletal complications and extend survival. While castration of dystrophin and utrophin double mutant (mdx-dm) mice to mimic pre-pubertal nadir androgen condition resulted in premature death, maintenance of androgen levels extended the survival. Non-steroidal selective-AR modulator, GTx-026, which selectively builds muscle and bone was tested in X-linked muscular dystrophy mice (mdx). GTx-026 significantly increased body weight, lean mass and grip strength by 60-80% over vehicle-treated mdx mice. While vehicle-treated castrated mdx mice exhibited cardiopulmonary impairment and fibrosis of heart and lungs, GTx-026 returned cardiopulmonary function and intensity of fibrosis to healthy control levels. GTx-026 elicits its musculoskeletal effects through pathways that are distinct from dystrophin-regulated pathways, making AR agonists ideal candidates for combination approaches. While castration of mdx-dm mice resulted in weaker muscle and shorter survival, GTx-026 treatment increased the muscle mass, function and survival, indicating that androgens are important for extended survival. These preclinical results support the importance of androgens and the need for intervention with AR agonists to treat DMD-affected boys. © The Author 2017. Published by Oxford University Press.

'Don't save her'- Sigmund Freud meets Project Pat: the rescue motif in hip-hop.

Science.gov (United States)

Fulmer, Richard H

2008-08-01

Freud originally explicated the dynamics of rescue wishes by describing men who fell in love with prostitutes. He saw this attempt at attachment as driven by the man's wish to repay his parents for giving him life. Many subsequent writers shift this emphasis, seeing rescue wishes as motivated by aggressive oedipal competition with the father. This article highlights the attachment aspects of Freud's original conception and traces how writers in the last three decades use the family romance rather than Oedipus as a model to view rescue wishes as having a more tender aspect. Rescue wishes are especially characteristic of the developmental stage of young adulthood. They at once attempt to repay the parental debt the young adult feels and serve as practice for the vicissitudes of the couple bond and the benign sacrifices of parenthood. Popular culture contains many vivid examples of Freud 's original description of the rescue-motif. A detailed examination of the rap song, Don't save her, demonstrates all the elements of Freud's original conception and the interpersonal risks of the rescue relationship. Three additional rap songs by other artists are briefly analyzed to show the extensive occurrence of the wish to rescue and its psychic and interpersonal dangers.

A Reliable Method for Rhythm Analysis during Cardiopulmonary Resuscitation

Directory of Open Access Journals (Sweden)

U. Ayala

2014-01-01

Full Text Available Interruptions in cardiopulmonary resuscitation (CPR compromise defibrillation success. However, CPR must be interrupted to analyze the rhythm because although current methods for rhythm analysis during CPR have high sensitivity for shockable rhythms, the specificity for nonshockable rhythms is still too low. This paper introduces a new approach to rhythm analysis during CPR that combines two strategies: a state-of-the-art CPR artifact suppression filter and a shock advice algorithm (SAA designed to optimally classify the filtered signal. Emphasis is on designing an algorithm with high specificity. The SAA includes a detector for low electrical activity rhythms to increase the specificity, and a shock/no-shock decision algorithm based on a support vector machine classifier using slope and frequency features. For this study, 1185 shockable and 6482 nonshockable 9-s segments corrupted by CPR artifacts were obtained from 247 patients suffering out-of-hospital cardiac arrest. The segments were split into a training and a test set. For the test set, the sensitivity and specificity for rhythm analysis during CPR were 91.0% and 96.6%, respectively. This new approach shows an important increase in specificity without compromising the sensitivity when compared to previous studies.

Bystander cardiopulmonary resuscitation (CPR) is a crucial therapy for sudden cardiac arrest. This appreciation produced immense efforts by professional organizations to train laypeople for CPR skills. However, the rate of CPR training is low and varies widely across communities. Several strategies are used in order to improve the rate of CPR training and are performed in some advanced countries. The Chinese CPR training in communities could gain enlightenment from them.

Rescue Medicine for Epilepsy: New Options for Education Settings.

Science.gov (United States)

Galemore, Cynthia A

2016-11-01

The American Academy of Pediatrics (AAP) recently published a clinical report recommending expanded options for seizure rescue medications in the school setting. School nurses rely on prescribing professionals for medical orders to manage children with epilepsy in the school setting. The report suggests additional medications beyond rectal diazepam gel along with discussing the purpose of the medications, the variations in prescribing practices for seizure rescue medications, inconsistencies in legislation based on jurisdictions, and the need for school medical orders for students with epilepsy. There are many issues faced by school personnel when caring for students with a diagnosis of epilepsy, chief among them the presence of licensed health professions for the school to be able to respond quickly and appropriately in the event of a seizure. School nurses can assist health care providers in determining the rescue medication most easily delivered and monitored in the variety of activities that are part of the school experience, including transportation to and from school, field trips, and before- and after-school activities, all beyond the regular classroom setting.

A Pilot Model for the NASA Simplified Aid for EVA Rescue (SAFER) (Single-Axis Pitch Task)

Science.gov (United States)

Handley, Patrick Mark

This thesis defines, tests, and validates a descriptive pilot model for a single-axis pitch control task of the Simplified Aid for EVA Rescue (SAFER). SAFER is a small propulsive jetpack used by astronauts for self-rescue. Pilot model research supports development of improved self-rescue strategies and technologies through insights into pilot behavior.This thesis defines a multi-loop pilot model. The innermost loop controls the hand controller, the middle loop controls pitch rate, and the outer loop controls pitch angle. A human-in-the-loop simulation was conducted to gather data from a human pilot. Quantitative and qualitative metrics both indicate that the model is an acceptable fit to the human data. Fuel consumption was nearly identical; time to task completion matched very well. There is some evidence that the model responds faster to initial pitch rates than the human, artificially decreasing the model's time to task completion. This pilot model is descriptive, not predictive, of the human pilot. Insights are made into pilot behavior from this research. Symmetry implies that the human responds to positive and negative initial conditions with the same strategy. The human pilot appears indifferent to pitch angles within 0.5 deg, coasts at a constant pitch rate 1.09 deg/s, and has a reaction delay of 0.1 s.

1999-08-15

To measure cardiopulmonary variables, including cardiac index, in dogs with naturally acquired gastric dilatation-volvulus (GDV). Prospective clinical study. 6 dogs with GDV. In addition to typical medical and surgical management of GDV, the dorsal metatarsal and pulmonary arteries and right atrium of the dogs were catheterized to obtain cardiopulmonary measurements before and during anesthesia and surgery. All dogs underwent gastropexy but none required gastrectomy. Mean cardiac index and mean arterial blood pressure for this small population of dogs with GDV were not significantly different from those reported for clinically normal awake or anesthetized dogs. Dogs with naturally acquired GDV without gastric necrosis may not have the classic characteristics, including decreased cardiac index and hypotension, of hypovolemic circulatory shock.

2016-06-01

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

Gas Concentration Prediction Based on the Measured Data of a Coal Mine Rescue Robot

Xiliang Ma

2016-01-01

Full Text Available The coal mine environment is complex and dangerous after gas accident; then a timely and effective rescue and relief work is necessary. Hence prediction of gas concentration in front of coal mine rescue robot is an important significance to ensure that the coal mine rescue robot carries out the exploration and search and rescue mission. In this paper, a gray neural network is proposed to predict the gas concentration 10 meters in front of the coal mine rescue robot based on the gas concentration, temperature, and wind speed of the current position and 1 meter in front. Subsequently the quantum genetic algorithm optimization gray neural network parameters of the gas concentration prediction method are proposed to get more accurate prediction of the gas concentration in the roadway. Experimental results show that a gray neural network optimized by the quantum genetic algorithm is more accurate for predicting the gas concentration. The overall prediction error is 9.12%, and the largest forecasting error is 11.36%; compared with gray neural network, the gas concentration prediction error increases by 55.23%. This means that the proposed method can better allow the coal mine rescue robot to accurately predict the gas concentration in the coal mine roadway.

Aiming at the multi-agent cooperative rescue in disaster, a multi-agent cooperative rescue algorithm based on impact degree and state prediction is proposed. Firstly, based on the influence of the information in the scene on the collaborative task, the influence degree function is used to filter the information. Secondly, using the selected information to predict the state of the system and Agent behavior. Finally, according to the result of the forecast, the cooperative behavior of Agent is guided and improved the efficiency of individual collaboration. The simulation results show that this algorithm can effectively solve the cooperative rescue problem of multi-agent and ensure the efficient completion of the task.

A competency framework for the business rescue practitioner profession

Marius Pretorius

2014-08-01

Research purpose: Competencies required by business rescue practitioners (BRPs to navigate a distressed venture were investigated. What BRPs actually ‘do’ during a rescue guided the development of a competency framework to inform future qualification guidelines for BRP education and accreditation. Motivation for the study: To investigate the research question: ‘What are the competencies that underlie the activities of a business rescue practitioner?’. Research design, approach and method: A modified ‘interview to the double’ (ITTD process was used to elicit instructions that a BRP would give to an imaginary ‘double’. These instructions were analysed and rated for importance, transferability, knowledge requirement and skills requirement; in conclusion, these instructions were ranked and subjected to a content analysis. Main findings: Based on the main activities that were derived from the practices and praxis, one assignment and four supra (higher-level competencies were consequent to the analysis. A BRP able to successfully navigate a distressed venture towards normal operations should demonstrate a high level of competency in sense-making, decision making and integration, achieved through collaboration as the central competency. Practical implications: Firstly, the study addresses educators’ need for a framework of competencies to guide education. Secondly, it paves the way for the Regulator to develop a qualifications framework for accreditation. Contribution: The findings gave structure to the competencies underlying the activities of a BRP to navigate a rescue. Pre-business and financial acumen appears limited without these competencies containing insight, experience, intuition, heuristics, tacit knowledge, perceptive induction and more.

Full Text Available Objective. There are many smartphone-based applications (apps for cardiopulmonary resuscitation (CPR training. We investigated the conformity and the learnability/usability of these apps for CPR training and real-life supports. Methods. We conducted a mixed-method, sequential explanatory study to assess CPR training apps downloaded on two apps stores in South Korea. Apps were collected with inclusion criteria as follows, Korean-language instruction, training features, and emergency supports for real-life incidents, and analyzed with two tests; 15 medical experts evaluated the apps’ contents according to current Basic Life Support guidelines in conformity test, and 15 nonmedical individuals examined the apps using System Usability Scale (SUS in the learnability/usability test. Results. Out of 79 selected apps, five apps were included and analyzed. For conformity (ICC, 0.95, p<0.001, means of all apps were greater than 12 of 20 points, indicating that they were well designed according to current guidelines. Three of the five apps yielded acceptable level (greater than 68 of 100 points for learnability/usability. Conclusion. All the included apps followed current BLS guidelines and a majority offered acceptable learnability/usability for layperson. Current and developmental smartphone-based CPR training apps should include accurate CPR information and be easy to use for laypersons that are potential rescuers in real-life incidents. For Clinical Trials. This is a clinical trial, registered at the Clinical Research Information Service (CRIS, cris.nih.go.kr, number KCT0001840.

The role of "rescue saccades" in tracking objects through occlusions.

Science.gov (United States)

Zelinsky, Gregory J; Todor, Andrei

2010-12-29

We hypothesize that our ability to track objects through occlusions is mediated by timely assistance from gaze in the form of "rescue saccades"-eye movements to tracked objects that are in danger of being lost due to impending occlusion. Observers tracked 2-4 target sharks (out of 9) for 20 s as they swam through a rendered 3D underwater scene. Targets were either allowed to enter into occlusions (occlusion trials) or not (no occlusion trials). Tracking accuracy with 2-3 targets was ≥ 92% regardless of target occlusion but dropped to 74% on occlusion trials with four targets (no occlusion trials remained accurate; 83%). This pattern was mirrored in the frequency of rescue saccades. Rescue saccades accompanied approximatlely 50% of the Track 2-3 target occlusions, but only 34% of the Track 4 occlusions. Their frequency also decreased with increasing distance between a target and the nearest other object, suggesting that it is the potential for target confusion that summons a rescue saccade, not occlusion itself. These findings provide evidence for a tracking system that monitors for events that might cause track loss (e.g., occlusions) and requests help from the oculomotor system to resolve these momentary crises. As the number of crises increase with the number of targets, some requests for help go unsatisfied, resulting in degraded tracking.

There is a search for rescue therapy against fetal origins of cardiovascular disease in pregnancy complicated by chronic fetal hypoxia, particularly following clinical diagnosis of fetal growth restriction (FGR). Melatonin protects the placenta in adverse pregnancy; however, whether melatonin protects the fetal heart and vasculature in hypoxic pregnancy independent of effects on the placenta is unknown. Whether melatonin can rescue fetal cardiovascular dysfunction when treatment commences following FGR diagnosis is also unknown. We isolated the effects of melatonin on the developing cardiovascular system of the chick embryo during hypoxic incubation. We tested the hypothesis that melatonin directly protects the fetal cardiovascular system in adverse development and that it can rescue dysfunction following FGR diagnosis. Chick embryos were incubated under normoxia or hypoxia (14% O2) from day 1 ± melatonin treatment (1 mg/kg/day) from day 13 of incubation (term ~21 days). Melatonin in hypoxic chick embryos rescued cardiac systolic dysfunction, impaired cardiac contractility and relaxability, increased cardiac sympathetic dominance, and endothelial dysfunction in peripheral circulations. The mechanisms involved included reduced oxidative stress, enhanced antioxidant capacity and restored vascular endothelial growth factor expression, and NO bioavailability. Melatonin treatment of the chick embryo starting at day 13 of incubation, equivalent to ca. 25 wk of gestation in human pregnancy, rescues early origins of cardiovascular dysfunction during hypoxic development. Melatonin may be a suitable antioxidant candidate for translation to human therapy to protect the fetal cardiovascular system in adverse pregnancy. © 2015 The Authors. Journal of Pineal Research.

Soares, João; Vale, Alberto; Ventura, Rodrigo

2015-01-01

Highlights: • Design of an omnidirectional vehicle equipped with cameras and laser range finders. • Two robotic manipulators that slide over the vehicle's body to perform independent tasks. • Architecture to connect the control system, communication, power, navigation and HMI. • An immersive interface HMI with augmented reality features with head mounted display. - Abstract: The remote handling (RH) plays an important role in nuclear test facilities, such as in ITER, for in-vessel and ex-vessel maintenance operations. Unexpected situations may occur when RH devices fail. Since no human being is allowed during the RH operations, a Multi-purpose Rescue Vehicle (MPRV) must be required for providing support in site. This paper proposes a design of a MPRV, i.e., a mobile platform equipped with different sensors and two manipulators with different sets of end-effectors. A human–machine interface is also proposed to remotely operate the MPRV and to carry out rescue and recovery operations.

Highlights: • Design of an omnidirectional vehicle equipped with cameras and laser range finders. • Two robotic manipulators that slide over the vehicle's body to perform independent tasks. • Architecture to connect the control system, communication, power, navigation and HMI. • An immersive interface HMI with augmented reality features with head mounted display. - Abstract: The remote handling (RH) plays an important role in nuclear test facilities, such as in ITER, for in-vessel and ex-vessel maintenance operations. Unexpected situations may occur when RH devices fail. Since no human being is allowed during the RH operations, a Multi-purpose Rescue Vehicle (MPRV) must be required for providing support in site. This paper proposes a design of a MPRV, i.e., a mobile platform equipped with different sensors and two manipulators with different sets of end-effectors. A human–machine interface is also proposed to remotely operate the MPRV and to carry out rescue and recovery operations.

Abstract There is a search for rescue therapy against fetal origins of cardiovascular disease in pregnancy complicated by chronic fetal hypoxia, particularly following clinical diagnosis of fetal growth restriction (FGR). Melatonin protects the placenta in adverse pregnancy; however, whether melatonin protects the fetal heart and vasculature in hypoxic pregnancy independent of effects on the placenta is unknown. Whether melatonin can rescue fetal cardiovascular dysfunction when treatment comm...

The emergence of the rescue effect from explicit within and between-patch dynamics in a metapopulation

Eriksson, Anders

2014-02-12

Immigration can rescue local populations from extinction, helping to stabilize a metapopulation. Local population dynamics is important for determining the strength of this rescue effect, but the mechanistic link between local demographic parameters and the rescue effect at the metapopulation level has received very little attention by modellers. We develop an analytical framework that allows us to describe the emergence of the rescue effect from interacting local stochastic dynamics. We show this framework to be applicable to a wide range of spatial scales, providing a powerful and convenient alternative to individual-based models for making predictions concerning the fate of metapopulations. We show that the rescue effect plays an important role in minimizing the increase in local extinction probability associated with high demographic stochasticity, but its role is more limited in the case of high local environmental stochasticity of recruitment or survival. While most models postulate the rescue effect, our framework provides an explicit mechanistic link between local dynamics and the emergence of the rescue effect, and more generally the stability of the whole metapopulation. © 2014 The Author(s) Published by the Royal Society.

Metallic tracheal stents have been used in the treatment of paediatric tracheomalacia for more than a decade. We describe a case in which critical airway obstruction occurred during removal of a welded tracheal stent using a rigid bronchoscope under general anaesthesia. Life-saving cardiopulmonary bypass was instituted urgently, and the welded stent was then removed successfully by directly opening the trachea.

Recent studies have shown that short, spaced trains of afferent stimulation produce much greater long-term potentiation (LTP) than that obtained with a single, prolonged stimulation episode. The present studies demonstrate that spaced training regimens, based on these LTP timing rules, facilitate learning in wild-type (WT) mice and can offset learning and synaptic signaling impairments in the fragile X mental retardation 1 (Fmr1) knockout (KO) model of fragile X syndrome. We determined that 5 min of continuous training supports object location memory (OLM) in WT but not Fmr1 KO mice. However, the same amount of training distributed across three short trials, spaced by one hour, produced robust long-term memory in the KOs. At least three training trials were needed to realize the benefit of spacing, and intertrial intervals shorter or longer than 60 min were ineffective. Multiple short training trials also rescued novel object recognition in Fmr1 KOs. The spacing effect was surprisingly potent: just 1 min of OLM training, distributed across three trials, supported robust memory in both genotypes. Spacing also rescued training-induced activation of synaptic ERK1/2 in dorsal hippocampus of Fmr1 KO mice. These results show that a spaced training regimen designed to maximize synaptic potentiation facilitates recognition memory in WT mice and can offset synaptic signaling and memory impairments in a model of congenital intellectual disability.

Full Text Available Cross-sectional study that assessed the quality of nursing records on cardiopulmonary resuscitation. Forty-two patients’ charts were reviewed in an intensive care unit, using the Utstein protocol. There was a predominance of men (54.8%, aged from 21-70 years old (38.1%, correction of acquired heart diseases (42.7%, with more than one pre-existing device (147. As immediate cause of cardiac arrest, hypotension predominated (48.3% and as the initial rhythm, bradycardia (37.5%. Only the time of death and time of arrest were recorded in 100% of the sample. Professional training in Advanced Life Support was not recorded. The causes of arrest and initial rhythm were recorded in 69% and 76.2% of the sample. Chest compressions, patent airway obtainment and defibrillation were recorded in less than 16%. Records were considered of low quality and may cause legal sanctions to professionals and do not allow the comparison of the effectiveness of the maneuvers with other centers.

2017-01-01

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

Objective: To investigate the situations of on-site rescue and traumatic features of victims involved in gas explosion accident in Hangzhou, so as to provide more data support for emergency medical rescues of the similar incidents of massive casualty. Methods: Two medical workers with a certain clinical experience were sent to Hangzhou 120 emergency medical centers to collect data of the on-site rescue on 21st July, 2017, including ambulance call-outs, on-site command and traffic conditions, and on-site triage and evacuation of the victims. They were then sent to the hospitals receiving the victims to investigate the situations of these victims including the general information (such as gender, age, admitted hospitals, and number of admission, discharge, and transferring in the first two weeks after the accident) and injury assessment [such as injury position and type, injury severity evaluation by New Injury Severity Scoring (NISS), and burn severity evaluation for victims with burns]. Results: (1) A total of 15 ambulances reached the accident site for rescue. The traffic and transportation were jammed and interrupted after this accident. On-site triage and distribution were disorderly conducted. (2) Clinical data of 53 victims were collected, including 24 males and 29 females, with the age of 8 to 70 (34±14) years old. They were sent into 6 hospitals in Hangzhou. Two victims died on the day of accident. Up to two weeks after this accident, 28 (52.8%) victims were discharged from the hospitals and received follow-up in outpatient department. Five victims with severe injuries were transferred to the other hospitals. (3) Based on the results of NISS, the injury severities were mild in 29 (54.7%) cases, moderate in 9 (17.0%) cases, serious in 3 (5.7%) cases, and severe in 12 (22.6%) cases. Those 2 dead victims were classified into the severe category due to the highest NISS score of 75. For all of the victims, skin and soft tissue defects were most common. Six (11

This is a follow up study on rescue workers participating in the primary rescue during and immediately after the explosion of a firework factory. We aimed to estimate the possible PTSD prevalence at five and 18 months post disaster, determining if the level of PTSD symptoms at 18 months could be predicted from factors measured at five months. We included measures of posttraumatic symptoms, social support, locus of control and demographic questions. The possible PTSD prevalence rose from 1.6% (n = 465) at five months post disaster to 3.1% (n = 130) at 18 months. A hierarchical linear regression predicted 59% of PTSD symptoms variance at 18 months post disaster. In the final regression, somatization explained the greatest part of the symptom variance (42%), followed by locus of control (29%) and major life events prior to and right after the disaster (23%). Rescue workers seemed to be relatively robust to traumatic exposure: The prevalence of possible PTSD in our study was even lower than previous studies, probably because of the less severe consequences of the disaster studied. Furthermore, we found that PTSD symptom level at 18 months post disaster was highly predicted by psychological factors, particularly by somatization. However, further investigations of traumatic responding are required in this population.

Full Text Available ABSTRACT Introduction Sudden death is a substantial public health problem, representing a major cause of mortality worldwide. Suitable initial care is essential for a good prognosis of these patients. Objectives To assess the knowledge of the 2010 guidelines for cardiopulmonary resuscitation (CPR among medical students in their final year of undergraduate training. Methods This was a cross-sectional study with a sample of 217 medical students enrolled in the sixth year of accredited medical schools in Brazil. A structured questionnaire with 27 items was used to record the sociodemographic characteristics of the participants and to assess their knowledge base of the 2010 ILCOR guidelines for CPR. Results Only fifty (23.04% out of 217 students achieved results considered as satisfactory in the written evaluation. The average score obtained was 56.74% correct answers. Seventeen percent of the students had never performed CPR maneuvers and 83.80% had never performed cardioversion or defibrillation. Conclusions The knowledge base of medical students regarding cardiopulmonary resuscitation is low. Considering these medical students are in their final year of medical school, this study reveals a worrisome scenario.

Standards have a significant role in showing the minimum level of optimal optimum and the expected performance. Since the perfusion technology staffs play an the leading role in providing the quality services to the patients undergoing open heart surgery with cardiopulmonary bypass machine, this study aimed to assess the standards on how Iranian perfusion technology staffs evaluate and manage the patients during the cardiopulmonary bypass process and compare their practice with the recommended standards by American Society of Extracorporeal Technology. In this descriptive study, data was collected from 48 Iranian public hospitals and educational health centers through a researcher-created questionnaire. The data collection questionnaire assessed the standards which are recommended by American Society of Extracorporeal Technology. Findings showed that appropriate measurements were carried out by the perfusion technology staffs to prevent the hemodilution and avoid the blood transfusion and unnecessary blood products, determine the initial dose of heparin based on one of the proposed methods, monitor the anticoagulants based on ACT measurement, and determine the additional doses of heparin during the cardiopulmonary bypass based on ACT or protamine titration. It was done only in 4.2% of hospitals and health centers. Current practices of cardiopulmonary perfusion technology in Iran are inappropriate based on the standards of American Society of Cardiovascular Perfusion. This represents the necessity of authorities' attention to the validation programs and development of the caring standards on one hand and continuous assessment of using these standards on the other hand.

Various studies have assessed the role of life experiences, including learning opportunities, living conditions and the quality of dog-human relationships, in the use of human cues and problem-solving ability. The current study investigates how and to what extent training affects the behaviour of dogs and the communication of dogs with humans by comparing dogs trained for a water rescue service and untrained pet dogs in the impossible task paradigm. Twenty-three certified water rescue dogs (the water rescue group) and 17 dogs with no training experience (the untrained group) were tested using a modified version of the impossible task described by Marshall-Pescini et al. in 2009. The results demonstrated that the water rescue dogs directed their first gaze significantly more often towards the owner and spent more time gazing toward two people compared to the untrained pet dogs. There was no difference between the dogs of the two groups as far as in the amount of time spent gazing at the owner or the stranger; neither in the interaction with the apparatus attempting to obtain food. The specific training regime, aimed at promoting cooperation during the performance of water rescue, could account for the longer gazing behaviour shown toward people by the water rescue dogs and the priority of gazing toward the owner.

Although often clinically silent, pancreatic cellular injury (PCI) is relatively frequent after cardiac surgery with cardiopulmonary bypass; and its etiology and time course are largely unknown. We defined PCI as the simultaneous presence of abnormal values of pancreatic isoamylase and immunoreactive trypsin (IRT). The frequency and time evolution of PCI were assessed in this condition using assays for specific exocrine pancreatic enzymes. Correlations with inflammatory markers were searched for preoperative risk factors. One hundred ninety-three patients submitted to cardiac surgery were enrolled prospectively. Blood IRT, amylase, pancreatic isoamylase, lipase, and markers of inflammation (alpha1-protease inhibitor, alpha2-macroglobulin, myeloperoxidase) were measured preoperatively and postoperatively until day 8. The postoperative increase in plasma levels of pancreatic enzymes and urinary IRT was biphasic in all patients: early after surgery and later (from day 4 to 8 after surgery). One hundred thirty-three patients (69%) experienced PCI, with mean IRT, isoamylase, and alpha1-protease inhibitor values higher for each sample than that in patients without PCI. By multiple regression analysis, we found preoperative values of plasma IRT >or=40 ng/mL, amylase >or=42 IU/mL, and pancreatic isoamylase >or=20 IU/L associated with a higher incidence of postsurgery PCI (P < 0.005). In the PCI patients, a significant correlation was found between the 4 pancreatic enzymes and urinary IRT, total calcium, myeloperoxidase, alpha1-protease inhibitor, and alpha2-macroglobulin. These data support a high prevalence of postoperative PCI after cardiac surgery with cardiopulmonary bypass, typically biphasic and clinically silent, especially when pancreatic enzymes were elevated preoperatively.

A variety of organizations redistribute surplus food to low-income populations through food rescue nutrition. Why volunteers participate in these charitable organizations is unclear. The aim of this study is to document the participation and motivations of volunteers who are involved specifically in food rescue nutrition. A cross-sectional study was conducted in two phases. In phase 1, a new instrument, Motivations to Volunteer Scale, was developed and validated in 40 participants (aged ≥18 years). In phase 2, the new scale and a demographics questionnaire were administered to 300 participants who were volunteering in food pantries and churches. The pilot study showed that Motivations to Volunteer Scale exhibited an internal consistency of Cronbach's α of 0.73 (P  0.05). The scale was validated also by comparison to the Volunteer Function Inventory (r = 0.86, P social life, and altruism. The mean motivation score of the 300 volunteers was 9.15 ± 0.17. Greater motivations were observed among participants who were aged >45 years, women, Hispanics, college/university graduates, physically inactive, non-smokers, and had an income ≥ $48,000. The Motivations to Volunteer Scale is a valid tool to assess why individuals volunteer in food rescue nutrition. The extent of motivations of participants was relatively high, and the primary reason for volunteering was altruism. Health professionals should be encouraged to participate in food redistribution.

Examining critical care nurses' critical incident stress after in hospital cardiopulmonary resuscitation (CPR).

Science.gov (United States)

Laws, T

2001-05-01

The object of this study was to determine if critical care nurses' emotional responses to having performed cardiopulmonary resuscitation were indicative of critical incident stress. A descriptive approach was employed using a survey questionnaire of 31 critical care nurses, with supportive interview data from 18 of those participants. Analysis of the data generated from the questionnaire indicated that the respondents experienced thought intrusion and avoidance behaviour. A majority of those interviewed disclosed that they had experienced a wide range of emotional stressors and physical manifestations in response to having performed the procedure. The findings from both questionnaire and interview data were congruent with signs of critical incident stress, as described in the literature. This has been found to be detrimental to employees' mental health status and, for this reason, employers have a duty of care to minimise the risk of its occurrence and to manage problems as they arise.

Saving the injured: Rescue behavior in the termite-hunting ant Megaponera analis.

Predators of highly defensive prey likely develop cost-reducing adaptations. The ant Megaponera analis is a specialized termite predator, solely raiding termites of the subfamily Macrotermitinae (in this study, mostly colonies of Pseudocanthotermes sp.) at their foraging sites. The evolutionary arms race between termites and ants led to various defensive mechanisms in termites (for example, a caste specialized in fighting predators). Because M. analis incurs high injury/mortality risks when preying on termites, some risk-mitigating adaptations seem likely to have evolved. We show that a unique rescue behavior in M. analis , consisting of injured nestmates being carried back to the nest, reduces combat mortality. After a fight, injured ants are carried back by their nestmates; these ants have usually lost an extremity or have termites clinging to them and are able to recover within the nest. Injured ants that are forced experimentally to return without help, die in 32% of the cases. Behavioral experiments show that two compounds, dimethyl disulfide and dimethyl trisulfide, present in the mandibular gland reservoirs, trigger the rescue behavior. A model accounting for this rescue behavior identifies the drivers favoring its evolution and estimates that rescuing enables maintenance of a 28.7% larger colony size. Our results are the first to explore experimentally the adaptive value of this form of rescue behavior focused on injured nestmates in social insects and help us to identify evolutionary drivers responsible for this type of behavior to evolve in animals.

Full Text Available The knowledge of past events and long-term series is a base to understand phenomena, analyze climate change and forecast future events. To increase long term series and their accuracy, NUNIEAU software, sort of “Digitizing Table”, was developed and distributed freely since 2006 by Cerema. It is an international reference in tide gauge record, but has been improved to widespread its used for river and rainfall record. The SCHAPI (the French national service for hydrometeorology and support to flood forecasting launched a tender to rescue the old data on rainfall and rivers available. Many improvements have been done to manage different types of rainfall charts. NUNIEAU was developed in French and is also available in English and Spanish version with collaboration of foreign institutes. Main challenge is not only to digitize old data but also assess the quality of digitized data.

Saengsuwan, J; Laubacher, M; Nef, T; Hunt, K J

2014-01-01

Robotics-assisted tilt table technology was introduced for early rehabilitation of neurological patients. It provides cyclical stepping movement and physiological loading of the legs. The aim of the present study was to assess the feasibility of this type of device for peak cardiopulmonary performance testing using able-bodied subjects. A robotics-assisted tilt table was augmented with force sensors in the thigh cuffs and a work rate estimation algorithm. A custom visual feedback system was employed to guide the subjects' work rate and to provide real time feedback of actual work rate. Feasibility assessment focused on: (i) implementation (technical feasibility), and (ii) responsiveness (was there a measurable, high-level cardiopulmonary reaction?). For responsiveness testing, each subject carried out an incremental exercise test to the limit of functional capacity with a work rate increment of 5 W/min in female subjects and 8 W/min in males. 11 able-bodied subjects were included (9 male, 2 female; age 29.6 ± 7.1 years: mean ± SD). Resting oxygen uptake (O_{2}) was 4.6 ± 0.7 mL/min/kg and O_{2}peak was 32.4 ± 5.1 mL/min/kg; this mean O_{2}peak was 81.1% of the predicted peak value for cycle ergometry. Peak heart rate (HRpeak) was 177.5 ± 9.7 beats/min; all subjects reached at least 85% of their predicted HRpeak value. Respiratory exchange ratio (RER) at O_{2}peak was 1.02 ± 0.07. Peak work rate) was 61.3 ± 15.1 W. All subjects reported a Borg CR10 value for exertion and leg fatigue of 7 or more. The robotics-assisted tilt table is deemed feasible for peak cardiopulmonary performance testing: the approach was found to be technically implementable and substantial cardiopulmonary responses were observed. Further testing in neurologically-impaired subjects is warranted.

Clinical Review: Management of weaning from cardiopulmonary bypass after cardiac surgery

Directory of Open Access Journals (Sweden)

Marc Licker

2012-01-01

Full Text Available A sizable number of cardiac surgical patients are difficult to wean off cardiopulmonary bypass (CPB as a result of structural or functional cardiac abnormalities, vasoplegic syndrome, or ventricular dysfunction. In these cases, therapeutic decisions have to be taken quickly for successful separation from CPB. Various crisis management scenarios can be anticipated which emphasizes the importance of basic knowledge in applied cardiovascular physiology, knowledge of pathophysiology of the surgical lesions as well as leadership, and communication between multiple team members in a high-stakes environment. Since the mid-90s, transoesophageal echocardiography has provided an opportunity to assess the completeness of surgery, to identify abnormal circulatory conditions, and to guide specific medical and surgical interventions. However, because of the lack of evidence-based guidelines, there is a large variability regarding the use of cardiovascular drugs and mechanical circulatory support at the time of weaning from the CPB. This review presents key features for risk stratification and risk modulation as well as a standardized physiological approach to achieve successful weaning from CPB.

In human carbonic anhydrase II (HCA II) the mutation of position 64 from histidine to alanine (H64A) disrupts the rate limiting proton transfer (PT) event, resulting in a reduction of the catalytic activity of the enzyme as compared to the wild-type. Potential of mean force (PMF) calculations utilizing the multistate empirical valence bond (MS-EVB) methodology for H64A HCA II give a PT free energy barrier significantly higher than that found in the wild-type enzyme. This high barrier, determined in the absence of exogenous buffer and assuming no additional ionizable residues in the PT pathway, indicates the likelihood of alternate enzyme pathways that utilize either ionizable enzyme residues (self-rescue) and/or exogenous buffers (chemical rescue). It has been shown experimentally that the catalytic activity of H64A HCA II can be chemically rescued to near wild type levels by the addition of the exogenous buffer 4-methylimidazole (4MI). Crystallographic studies have identified two 4MI binding sites, yet site specific mutations intended to disrupt 4MI binding have demonstrated these sites to be non-productive. In the present work MS-EVB simulations show that binding of 4MI near Thr199 in the H64A HCA II mutant, a binding site determined by NMR spectroscopy, results in a viable chemical rescue pathway. Additional viable rescue pathways are also identified where 4MI acts as a proton transport intermediary from the active site to ionizable residues on the rim of the active site, revealing a probable mode of action for the chemical rescue pathway PMID:21452838

Whether reduced activity level and exercise intolerance precede the clinical diagnosis of cardiopulmonary disorders in smokers is not known. We examined activity level and exercise test outcomes in a young population-based sample without overt cardiopulmonary disease, differentiating by smoking history. This was a multiyear cross-sectional study using United States National Health and Nutrition Examination Survey data from 1999-2004. Self-reported activity level and incremental exercise treadmill testing were obtained on survey participants ages 20-49 years, excluding individuals with cardio-pulmonary disease. Three thousand seven hundred and one individuals completed exercise testing. Compared to never smokers, current smokers with >10 pack years reported significantly higher odds of little or no recreation, sport, or physical activity (adjusted OR 1.62; 95% CI 1.12-2.35). Mean perceived exertion ratings (Borg 6-20) at an estimated standardized workload were significantly greater among current smokers (18.3-18.6) compared to never (17.3) and former smokers (17.9) (psmoking abstinence was associated with significantly lower likelihood of low estimated peak oxygen uptake categorization (psmoking cessation, these results set the stage for future studies that examine mechanisms of activity restriction in young smokers and the utility of measures of activity restriction in the earlier diagnosis of smoking-related diseases.

Glycoprotein cytoplasmic domain sequences required for rescue of a vesicular stomatitis virus glycoprotein mutant

International Nuclear Information System (INIS)

Whitt, M.A.; Chong, L.; Rose, J.K.

1989-01-01

The authors have used transient expression of the wild-type vesicular stomatitis virus (VSV) glycoprotein (G protein) from cloned cDNA to rescue a temperature-sensitive G protein mutant of VSV in cells at the nonpermissive temperature. Using cDNAs encoding G proteins with deletions in the normal 29-amino-acid cytoplasmic domain, they determined that the presence of either the membrane-proximal 9 amino acids or the membrane-distal 12 amino acids was sufficient for rescue of the temperature-sensitive mutant. G proteins with cytoplasmic domains derived from other cellular or viral G proteins did not rescue the mutant, nor did G proteins with one or three amino acids of the normal cytoplasmic domain. Rescue correlated directly with the ability of the G proteins to be incorporated into virus particles. This was shown by analysis of radiolabeled particles separated on sucrose gradients as well as by electron microscopy of rescued virus after immunogold labeling. Quantitation of surface expression showed that all of the mutated G proteins were expressed less efficiently on the cell surface than was wild-type G protein. However, they were able to correct for differences in rescue efficiency resulting from differences in the level of surface expression by reducing wild-type G protein expression to levels equivalent to those observed for the mutated G proteins. The results provide evidence that at least a portion of the cytoplasmic domain is required for efficient assembly of the VSV G protein into virions during virus budding

[Purpose] The purpose of this study was to examine the effect of modified Pilates exercise on cardiopulmonary function in chronic stroke patients. [Subjects and Methods] Twenty participants (age, 62.7 ± 7.3 years; height, 163.3 ± 8.5 cm; weight, 68.8 ± 10.3 kg) were recruited for this study, and randomly allocated to the modified Pilates exercise group (n=10) or the control group (n=10). Graded submaximal treadmill exercise test was used to examine the status of patients' cardiopulmonary function, based on maximal oxygen intake, at the end of a patient's exercise tolerance limit. [Results] The resting heart rates, maximal oxygen intake, and maximal oxygen intake per kilogram were significantly different after 8 weeks of modified Pilates exercise. In addition, these variables were also significantly different between the Pilates and control groups after 8 weeks. [Conclusion] This study has demonstrated that 8 weeks of modified Pilates exercise program can have a positive influence on patients with chronic stroke, potentially by enhancing the cardiopulmonary function, which may have positive implications for increasing their functional ability.

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

Total liquid ventilation (TLV) with perfluorocarbons has shown to improve cardiopulmonary function in the injured and immature lung; however there remains controversy over the normal lung. Hemodynamic effects of TLV in the normal lung currently remain undetermined. This study compared changes in cardiopulmonary and circulatory function caused by either liquid or gas tidal volume ventilation. In a prospective, controlled study, 12 non-injured anesthetized, adult New Zealand rabbits were primarily conventionally gas-ventilated (CGV). After instrumentation for continuous recording of arterial (AP), central venous (CVP), left artrial (LAP), pulmonary arterial pressures (PAP), and cardiac output (CO) animals were randomized into (1) CGV group and (2) TLV group. In the TLV group partial liquid ventilation was initiated with instillation of perfluoroctylbromide (12 ml/kg). After 15 min, TLV was established for 3 hr applying a volume-controlled, pressure-limited, time-cycled ventilation mode using a double-piston configured TLV. Controls (CGV) remained gas-ventilated throughout the experiment. During TLV, heart rate, CO, PAP, MAP, CVP, and LAP as well as derived hemodynamic variables, arterial and mixed venous blood gases, oxygen delivery, PVR, and SVR did not differ significantly compared to CGV. Liquid tidal volumes suitable for long-term TLV in non-injured rabbits do not significantly impair CO, blood pressure, and oxygen dynamics when compared to CGV. Copyright © 2011 Wiley-Liss, Inc.

Gravity and the Evolution of Cardiopulmonary Morphology in Snakes

Lillywhite, Harvey B.; Albert, James S.; Sheehy, Coleman M.; Seymour, Roger S.

2011-01-01

Physiological investigations of snakes have established the importance of heart position and pulmonary structure in contexts of gravity effects on blood circulation. Here we investigate morphological correlates of cardiopulmonary physiology in contexts related to ecology, behavior and evolution. We analyze data for heart position and length of vascular lung in 154 species of snakes that exhibit a broad range of characteristic behaviors and habitat associations. We construct a composite phylogeny for these species, and we codify gravitational stress according to species habitat and behavior. We use conventional regression and phylogenetically independent contrasts to evaluate whether trait diversity is correlated with gravitational habitat related to evolutionary transitions within the composite tree topology. We demonstrate that snake species living in arboreal habitats, or which express strongly climbing behaviors, possess relatively short blood columns between the heart and the head, as well as relatively short vascular lungs, compared to terrestrial species. Aquatic species, which experience little or no gravity stress in water, show the reverse – significantly longer heart–head distance and longer vascular lungs. These phylogenetic differences complement the results of physiological studies and are reflected in multiple habitat transitions during the evolutionary histories of these snake lineages, providing strong evidence that heart–to–head distance and length of vascular lung are co–adaptive cardiopulmonary features of snakes.

PSO-Based Robot Path Planning for Multisurvivor Rescue in Limited Survival Time

Directory of Open Access Journals (Sweden)

N. Geng

2014-01-01

Full Text Available Since the strength of a trapped person often declines with time in urgent and dangerous circumstances, adopting a robot to rescue as many survivors as possible in limited time is of considerable significance. However, as one key issue in robot navigation, how to plan an optimal rescue path of a robot has not yet been fully solved. This paper studies robot path planning for multisurvivor rescue in limited survival time using a representative heuristic, particle swarm optimization (PSO. First, the robot path planning problem including multiple survivors is formulated as a discrete optimization one with high constraint, where the number of rescued persons is taken as the unique objective function, and the strength of a trapped person is used to constrain the feasibility of a path. Then, a new integer PSO algorithm is presented to solve the mathematical model, and several new operations, such as the update of a particle, the insertion and inversion operators, and the rapidly local search method, are incorporated into the proposed algorithm to improve its effectiveness. Finally, the simulation results demonstrate the capacity of our method in generating optimal paths with high quality.

Design and rescue scenario of common repair equipment for in-vessel components in ITER hot cell

Kakudate, Satoshi; Takeda, Nobukazu; Nakahira, Masataka; Shibanuma, Kiyoshi

2006-06-01

Transportation of the in-vessel components to be repaired in the ITER hot cell is carried by two kinds of transporters, i.e., overhead cranes and floor vehicles. The access area for repair operations in the hot cell is duplicated by these transporters. Clear sharing of the respective roles of these transporters with the minimum duplication is therefore useful for rationalization. The overhead cranes, which are independently installed in the respective cells in the hot sell, cannot pass through the components to be repaired between cells, i.e., receiving cell and refurbishment cell as an example. If the floor vehicle with simple mechanisms can cover the inaccessible area for the overhead cranes, a global transporter system in the hot cell will be simplified and the reliability will be increased. Based on this strategy, the overhead crane and floor vehicle concepts are newly proposed. The overhead crane has an adapter for change of the end-effectors, which can be easily changed, to grasp many kinds of components to be repaired. The floor vehicle, which is equipped with wheel mechanisms for transportation, is just to pass through the components between cells with only straight (linear) motion on the floor. The simple wheel mechanism can solve the spread of the dust, which is the critical issue of the original air bearing mechanism for traveling in the 2001 FDR design. Rescue scenarios and procedures in the hot cell are also studied in this report. The proposed rescue crane has major two functions for rescue operations of the hot cell facility, i.e., one for the overhead crane and the other for refurbishment equipment such as workstation for divertor repair. The rescue of the faulty overhead crane is carried out using the rescue tool installed on the rescue crane or directly traveled by pushing/pulling by the rescue crane after docking on the faulty overhead crane. For the rescue of the workstation, the rescue crane consists of a telescopic manipulator (maximum length

The National Institute for Occupational Safety and Health, together with LightsOn Safety Solutions, evaluated 2 versions of a multi-gas simulated gas monitor system (GMS) in separate field trials with mine rescue teams. This paper described the GMS wireless simulation tool along with its development and testing. It also described the GMS functions for the initial phase of testing as well as plans for the next phase of research which may introduce tracking and automation features. The GMS requires a personal computer and uses a wireless local area network. The GMS teaches mine rescue members about gas detection and helps them understand the importance of gas concentrations. In addition, it promotes decision-making actions by team members and offers a more realistic method of receiving gas concentration readings using a simulated hand-held gas detector. The purpose of the evaluation was to determine if the electronic placard in the GMS could be used by mine rescue teams instead of the currently used cardboard placards, and if the functionality of the device was suitable, reliable and practical. Results from the second field trial demonstrated improvements with the GMS over the original prototype technology, particularly with regards to wireless and connectivity issues. The GMS was successfully incorporated into the mine rescue exercises as planned, with very few problems encountered. 4 refs., 2 figs.

Extracorporeal membrane oxygenation (ECMO) has been repeatedly used to rescue patients with cardiopulmonary arrest. However, its clinical utility in endocrine emergencies remains unclear. Herein, we describe a case series of 12 patients presenting with refractory shock secondary to endocrine emergencies who were rescued by ECMO support. Patients were identified between 2005 and 2012 from our ECMO registry. The diagnostic distribution was as follows: pheochromocytoma crisis (n = 4), thyroid storm (n = 5), and diabetic ketoacidosis (n = 3). The initial presentation of pheochromocytoma crisis was indistinguishable from acute myocardial infarction (AMI) and frequently accompanied by paroxysmal hypertension and limb ischemia. Thyroid storm was characterized by hyperbilirubinemia and severe gastrointestinal bleeding, whereas neurological symptoms were common in diabetic ketoacidosis. The clinical outcomes of patients with endocrine emergencies were compared with those of 80 cases with AMI who received ECMO because of cardiogenic shock. The cardiac function and the general conditions showed a significantly faster recovery in patients with endocrine emergencies than in those with AMI. We conclude that ECMO support can be clinically useful in endocrine emergencies. The screening of endocrine diseases should be considered during the resuscitation of patients with refractory circulatory shock.

Acute and Subacute Effects of Urban Air Pollution on Cardiopulmonary Emergencies and Mortality: Time Series Studies in Austrian Cities

Directory of Open Access Journals (Sweden)

Daniel Rabczenko

2013-10-01

Full Text Available Daily pollution data (collected in Graz over 16 years and in the Linz over 18 years were used for time series studies (GAM and case-crossover on the relationship with daily mortality (overall and specific causes of death. Diagnoses of patients who had been transported to hospitals in Linz were also available on a daily basis from eight years for time series analyses of cardiopulmonary emergencies. Increases in air pollutant levels over several days were followed by increases in mortality and the observed effects increased with the length of the exposure window considered, up to a maximum of 15 days. These mortality changes in Graz and Linz showed similar patterns like the ones found before in Vienna. A significant association of mortality could be demonstrated with NO2, PM2.5 and PM10 even in summer, when concentrations are lower and mainly related to motor traffic. Cardiorespiratory ambulance transports increased with NO2/PM2.5/PM10 by 2.0/6.1/1.7% per 10 µg/m³ on the same day. Monitoring of NO2 (related to motor traffic and fine particulates at urban background stations predicts acute effects on cardiopulmonary emergencies and extended effects on cardiopulmonary mortality. Both components of urban air pollution are indicators of acute cardiopulmonary health risks, which need to be monitored and reduced, even below current standards.

Full Text Available Abstract Background Hemodynamic function may be depressed in the early postoperative stages after cardiac surgery. The aim of this study was the analysis of the myocardial contractility in neonates after cardiopulmonary bypass (CPB and mild hypothermia. Methods Three indices of left ventricular myocardial contractile function (dP/dt, (dP/dt/P, and wall thickening were studied up to 6 hours after CPB in neonatal piglets (CPB group; n = 4. The contractility data were analysed and then compared to the data of newborn piglets who also underwent median thoracotomy and instrumentation for the same time intervals but without CPB (non-CPB group; n = 3. Results Left ventricular dP/dtmax and (dP/dtmax/P remained stable in CPB group, while dP/dtmax decreased in non-CPB group 5 hours postoperatively (1761 ± 205 mmHg/s at baseline vs. 1170 ± 205 mmHg/s after 5 h; p max and (dP/dtmax/P there were no statistically significant differences between the two groups. Comparably, although myocardial thickening decreased in the non-CPB group the differences between the two groups were not statistically significant. Conclusions The myocardial contractile function in survived neonatal piglets remained stable 6 hours after cardiopulmonary bypass and mild hypothermia probably due to regional hypercontractility.

Evolutionary rescue: linking theory for conservation and medicine.

Evolutionary responses that rescue populations from extinction when drastic environmental changes occur can be friend or foe. The field of conservation biology is concerned with the survival of species in deteriorating global habitats. In medicine, in contrast, infected patients are treated with chemotherapeutic interventions, but drug resistance can compromise eradication of pathogens. These contrasting biological systems and goals have created two quite separate research communities, despite addressing the same central question of whether populations will decline to extinction or be rescued through evolution. We argue that closer integration of the two fields, especially of theoretical understanding, would yield new insights and accelerate progress on these applied problems. Here, we overview and link mathematical modelling approaches in these fields, suggest specific areas with potential for fruitful exchange, and discuss common ideas and issues for empirical testing and prediction.

Out-of-hospital cardiac arrest (OHCA) affects 134 per 100,000 citizens annually. Extracorporeal cardiopulmonary resuscitation (ECPR), providing mechanical circulatory support, may improve the likelihood of survival among those with refractory OHCA. Compared with in-hospital ECPR candidates, those in the out-of-hospital setting tend to be sudden unexpected arrests in younger and healthier patients. The aims of this review were to summarize, and identify the limitations of, the evidence evaluating ECPR for OHCA, and to provide an approach for ECPR program application. Although there are many descriptions of ECPR-treated cohorts, we identified a paucity of robust data showing ECPR effectiveness compared with conventional resuscitation. However, it is highly likely that ECPR, provided after a prolonged attempt with conventional resuscitation, does benefit select patient populations compared with conventional resuscitation alone. Although reliable data showing the optimal patient selection criteria for ECPR are lacking, most implementations sought young previously healthy patients with rapid high-quality cardiopulmonary resuscitation. Carefully planned development of ECPR programs, in high-performing emergency medical systems at experienced extracorporeal membrane oxygenation centres, may be reasonable as part of systematic efforts to determine ECPR effectiveness and globally improve care. Protocol evaluation requires regional-level assessment, examining the incremental benefit of survival compared with standard care, while accounting for resource utilization.

Full Text Available A key issue in conservation biology is recognizing and bridging the gap between scientific results and specific action. We examine sea turtles—charismatic yet endangered flagship species—in the Mediterranean, a sea with historically high levels of exploitation and 22 coastal nations. We take sea turtle rescue facilities as a visible measure for implemented conservation action. Our study yielded 34 confirmed sea turtle rescue centers, 8 first-aid stations, and 7 informal rescue institutions currently in operation. Juxtaposing these facilities to known sea turtle distribution and threat hotspots reveals a clear disconnect. Only 14 of the 22 coastal countries had centers, with clear gaps in the Middle East and Africa. Moreover, the information flow between centers is apparently limited. The populations of the two species nesting in the Mediterranean, the loggerhead Caretta caretta and the green turtle Chelonia mydas, are far below historical levels and face a range of anthropogenic threats at sea and on land. Sea turtle rescue centers are acknowledged to reduce mortality in bycatch hotspots, provide a wealth of scientific data, and raise public awareness. The proposal for a Mediterranean-wide rescue network as published by the Regional Activity Centre for Specially Protected Areas a decade ago has not materialized in its envisioned scope. We discuss the efficiency, gaps, and needs for a rescue network and call for establishing additional rescue centers and an accompanying common online database to connect existing centers. This would provide better information on the number and types of rescue facilities on a Mediterranean scale, improve communication between these facilities, enhance standardization of procedures, yield large-scale data on the number of treated turtles and their injuries, and thus provide valuable input for targeted conservation measures.

To determine selected cardiopulmonary values and baroreceptor response in conscious green iguanas (Iguana iguana) and to evaluate the use of blood gas analysis and pulse oximetry in this species. 15 healthy juvenile green iguanas. Baseline cardiopulmonary values were determined in 15 conscious iguanas breathing room air. Effects of 100% O(2) inspiration were also measured (n = 6), and the baroreceptor reflex was characterized by exponential sigmoidal curve fitting analysis. Conscious iguanas had a mean ± SD resting heart rate of 52 ± 8 beats/min, respiratory rate of 28 ± 6 breaths/min, and systolic, mean, and diastolic arterial blood pressures of 69 ± 10 mm Hg, 62 ± 12 mm Hg, and 56 ± 13 mm Hg, respectively. Mean arterial pH at 37°C was 7.29 ± 0.11, PaO(2) was 81 ± 10 mm Hg, and PaCO(2) was 42 ± 9 mm Hg; corrected for a body temperature of 30°C, mean arterial pH at 37°C was 7.382 ±0.12, PaO(2) was 54 ± 15 mm Hg, and PaCO(2) was 32 ± 7 mm Hg. Inspiration of 100% O(2) did not change heart and respiratory rates but increased PaO(2) to 486 ± 105 mm Hg (corrected value, 437 ± 96 mm Hg). A baroreceptor reflex was evident, with mean heart rates ranging from 30 ± 3 beats/min to 63 ± 5 beats/min and mean arterial blood pressures ranging from 42 ± 3 mm Hg to 58 ± 3 mm Hg. This study provided needed information on cardiopulmonary values in healthy green iguanas, the application and limitation of arterial and venous blood gas analysis, and the accuracy of pulse oximetry.

2017-03-01

Full Text Available Several studies in patients with chronic obstructive pulmonary disease (COPD have shown that whole-body vibration training (WBVT has beneficial effects on exercise capacity. However, the acute cardiopulmonary demand during WBVT remains unknown and was therefore investigated in this study. Ten patients with severe COPD (forced expiratory volume in 1 s: 38±8% predicted were examined on two consecutive days. On day one, symptom-limited cardiopulmonary exercise testing was performed on a cycle ergometer. The next day, six bouts of repeated squat exercises were performed in random order for one, two or three minutes either with or without WBVT while metabolic demands were simultaneously measured. Squat exercises with or without WBVT induced comparable ventilatory efficiency (minute ventilation (VE/carbon dioxide production (V′CO2: 38.0±4.4 with WBVT versus 37.4±4.1 without, p=0.236. Oxygen uptake after 3 min of squat exercises increased from 339±40 mL·min−1 to 1060±160 mL·min−1 with WBVT and 988±124 mL min−1 without WBV (p=0.093. However, there were no significant differences between squat exercises with and without WBVT in oxygen saturation (90±4% versus 90±4%, p=0.068, heart rate (109±13 bpm versus 110±15 bpm, p=0.513 or dyspnoea (Borg scale 5±2 versus 5±2, p=0.279. Combining squat exercises with WBVT induced a similar cardiopulmonary response in patients with severe COPD compared to squat exercises without WBVT. Bearing in mind the small sample size, WBVT might be a feasible and safe exercise modality even in patients with severe COPD.

Transmission of feline immunodeficiency virus (FIV) among cohabiting cats in two cat rescue shelters.

Science.gov (United States)

Litster, Annette L

2014-08-01

Conflicting accounts have been published in the veterinary literature regarding transmission of feline immunodeficiency virus (FIV) between cohabiting cats in mixed households, and the mechanics of possible casual transmission, if it occurs, are poorly understood. Similarly, there are conflicting reports of vertical transmission of FIV. The aim of the present study was to document the FIV serological status of cats taken into two rescue shelters. At rescue shelter 1 (Rescue 1), cats cohabited in a multi-cat household of FIV-negative and naturally-infected, FIV-positive cats. A study was performed that combined a retrospective review of records of FIV serological status at intake (Test 1) and prospective FIV serological testing (Tests 2 and 3). Retrospective records were analyzed at rescue shelter 2 (Rescue 2), where FIV-positive queens with litters of nursing kittens were taken into the shelter, before being rehomed. FIV serology was performed on all kittens after weaning. Initial test results (Test 1) for 138 cohabiting cats from Rescue 1 showed that there were 130 FIV-negative cats and eight FIV-positive cats (six male neutered and two female spayed). A second test (Test 2), performed in 45 of the FIV-negative and five of the FIV-positive cats at median 28 months after Test 1 (range, 1 month to 8.8 years) showed that results were unchanged. Similarly, a third test (Test 3), performed in four of the original FeLV-negative cats and one remaining FIV-positive cat at median 38 months after Test 1 (range, 4 months to 4 years), also showed that results were unchanged. These results show a lack of evidence of FIV transmission, despite years of exposure to naturally-infected, FIV-positive cats in a mixed household. At Rescue 2, records were available from five FIV-positive queens with 19 kittens. All 19 kittens tested FIV-negative, suggesting that vertical transmission had not occurred.

2007-12-01

In order to identify the characteristics of subclinical hypothyroidism (SH) during physical stress and its recovery, 15 SH patients and 16 healthy women were compared by a treadmill cardiopulmonary test. Means of variables were analyzed by the Mann-Whitney U test. Patients obtained lower values for peak expired fraction of O2 (14.90+/-1.05 x 16+/-1.14%; p = 0.014); systolic blood pressure variation (34.33+/-17.92 x 52.50+/-17.22; p = 0.009); exercise duration (8.83+/-2.91 x 14.5+/-5.63 min; p = 0.0005), maximal test load (11.6+/-4.22 x 18.94+/-5.45%; p = 0.0004), as well as tendencies in gas exchange ratio and peak heart rate. Between the first and the third recovery minutes, there was a reduction of only 0.71 mmHg in the diastolic blood pressure, whereas there was a 5.33-mmHg reduction to control group (p = 0.0009) (slower recovery of patients). It is presumable that SH may cause cardiopulmonary dysfunctions, with higher sensibility to the parameters previously cited.

Full Text Available ObjectivesClinical trials of either pulmonary perfusion or ventilation during cardiopulmonary bypass are equivocal. We hypothesized that to achieve significant improvement in outcomes both interventions had to be concurrent.DesignRetrospective case-control studySettingsMajor academic tertiary referral medical centerParticipants274 consecutive patients who underwent open heart surgery with cardiopulmonary bypass 2009 - 2013.InterventionsThe outcomes of 86 patients who received pulmonary perfusion and ventilation during cardiopulmonary bypass were retrospectively compared to the control group of 188 patients.Measurements and Main ResultsRespiratory complications rates were similar in both groups (33.7% vs. 33.5%, as were the rates of postoperative pneumonia (4.7% vs. 4.3%, pleural effusions (13.9% vs. 12.2% and re-intubations (9.3% vs. 9.1%. Rates of adverse postoperative cardiac events including ventricular tachycardia (9.3% vs. 8.5% and atrial fibrillation (33.7% vs. 28.2% were equivalent in both groups. Incidence of sepsis (8.1% vs. 5.3%, postoperative stroke (2.3% vs. 2.1%, acute kidney injury (2.3% vs. 3.7% and renal failure (5.8% vs. 3.7% were likewise comparable. Despite similar transfusion requirements, coagulopathy (12.8% vs. 5.3%, p=0.031 and the need for mediastinal re-exploration (17.4% vs. 9.6%, p=0.0633 were observed more frequently in the pulmonary perfusion and ventilation group, but the difference did not reach the statistical significance. ICU and hospital stays, and the ICU readmission rates (7.0% vs. 8.0% were similar in both groups.ConclusionsSimultaneous pulmonary perfusion and ventilation during cardiopulmonary bypass were not associated with improved clinical outcomes.

Full Text Available Indonesia is a popular tourist destination which has potential for drowning cases. Therefore, required knowledge of adult basic life support to be able to deal with such cases in the field. Basic life support in an act to maintain airway and assist breathing and circulation without the use of tools other than simple breathing aids. The most important factor that determines the outcome of drowning event is the duration and severity of hypoxia induced. The management of near drowning at the scene include the rescue of victim from the water, rescue breathing, chest compression, cleaning the vomit substances which allowing blockage of the airway, prevent loss of body heat, and transport the victim to nearest emergency department for evaluation and monitoring.

Regular exercise increases exercise self-efficacy and health-related quality of life (HRQOL); however, the mechanisms are unknown. We examined the associations of exercise adherence and physiological improvements with changes in exercise self-efficacy and HRQOL. Middle-aged adults (N = 202) were randomized to 12 months aerobic exercise (360 minutes/week) or control. Weight, waist circumference, percent body fat, cardiopulmonary fitness, HRQOL (SF-36), and exercise self-efficacy were assessed at baseline and 12 months. Adherence was measured in minutes/day from activity logs. Exercise adherence was associated with reduced bodily pain, improved general health and vitality, and reduced role-emotional scores (P(trend) ≤ 0.05). Increased fitness was associated with improved physical functioning, bodily pain and general health scores (P(trend) ≤ 0.04). Reduced weight and percent body fat were associated with improved physical functioning, general health, and bodily pain scores (P(trend) exercise adherence, increased cardiopulmonary fitness and reduced weight, waist circumference and percent body fat were associated with increased exercise self-efficacy (P(trend) exercise programs to induce changes in cardiopulmonary fitness and body composition may lead to greater improvements in HRQOL and self-efficacy that could promote exercise maintenance.

We examined the relationship of changes in partial pressure of carbon dioxide on cerebral blood flow responsiveness in 20 pediatric patients undergoing hypothermic cardiopulmonary bypass. Cerebral blood flow was measured during steady-state hypothermic cardiopulmonary bypass with the use of xenon 133 clearance methodology at two different arterial carbon dioxide tensions. During these measurements there was no significant change in mean arterial pressure, nasopharyngeal temperature, pump flow rate, or hematocrit value. Cerebral blood flow was found to be significantly greater at higher arterial carbon dioxide tensions (p less than 0.01), so that for every millimeter of mercury rise in arterial carbon dioxide tension there was a 1.2 ml.100 gm-1.min-1 increase in cerebral blood flow. Two factors, deep hypothermia (18 degrees to 22 degrees C) and reduced age (less than 1 year), diminished the effect carbon dioxide had on cerebral blood flow responsiveness but did not eliminate it. We conclude that cerebral blood flow remains responsive to changes in arterial carbon dioxide tension during hypothermic cardiopulmonary bypass in infants and children; that is, increasing arterial carbon dioxide tension will independently increase cerebral blood flow

Cerebral blood flow was measured in 20 patients by xenon 133 clearance methodology during nonpulsatile hypothermic cardiopulmonary bypass to determine the effect of age on regional cerebral blood flow during these conditions. Measurements of cerebral blood flow at varying perfusion pressures were made in patients arbitrarily divided into two age groups at nearly identical nasopharyngeal temperature, hematocrit value, and carbon dioxide tension and with equal cardiopulmonary bypass flows of 1.6 L/min/m2. The range of mean arterial pressure was 30 to 110 mm Hg for group I (less than or equal to 50 years of age) and 20 to 90 mm Hg for group II (greater than or equal to 65 years of age). There was no significant difference (p = 0.32) between the mean arterial pressure in group I (54 +/- 28 mm Hg) and that in group II (43 +/- 21 mm Hg). The range of cerebral blood flow was 14.8 to 29.2 ml/100 gm/min for group I and 13.8 to 37.5 ml/100 gm/min for group II. There was no significant difference (p = 0.37) between the mean cerebral blood flow in group I (21.5 +/- 4.6 ml/100 gm/min) and group II (24.3 +/- 8.1 ml/100 gm/min). There was a poor correlation between mean arterial pressure and cerebral blood flow in both groups: group I, r = 0.16 (p = 0.67); group II, r = 0.5 (p = 0.12). In 12 patients, a second cerebral blood flow measurements was taken to determine the effect of mean arterial pressure on cerebral blood flow in the individual patient. Changes in mean arterial pressure did not correlate with changes in cerebral blood flow (p less than 0.90). We conclude that age does not alter cerebral blood flow and that cerebral blood flow autoregulation is preserved in elderly patients during nonpulsatile hypothermic cardiopulmonary bypass

The space-based Public Service Platform (PSP) is a multibeam, high-gain communications relay satellite that can provide a variety of functions for a large number of people on earth equipped with extremely small, very low cost transceivers. This paper describes the PSP concept, the rationale used to derive the concept, the criteria for selecting specific communication functions to be performed, and the advantages of performing such functions via satellite. The discussion focuses on the benefits of using a PSP for natural disaster warning; control of attendant rescue/assistance operations; and rescue of people in downed aircraft, aboard sinking ships, lost or injured on land.

Conclusions: Air pollution can aggravate chronic cardiopulmonary disease. In the current study, one of the most important air pollutants in Shiraz was the PM 10 component. Mechanical processes, such as wind blowing from neighboring countries, is the most important parameter increasing PM 10 in Shiraz to alarming conditions. The average monthly variation in PSI values of air pollutants such as NO 2 , CO, and SO 2 were lower than standard limits. Moreover, there was no significant correlation between the average monthly variation in PSI of NO 2 , CO, PM 10, and SO 2 and the number of those expired from cardiopulmonary disease in Shiraz.

The yeast complex I equivalent NADH dehydrogenase rescues pink1 mutants.

Directory of Open Access Journals (Sweden)

Sven Vilain

2012-01-01

Full Text Available Pink1 is a mitochondrial kinase involved in Parkinson's disease, and loss of Pink1 function affects mitochondrial morphology via a pathway involving Parkin and components of the mitochondrial remodeling machinery. Pink1 loss also affects the enzymatic activity of isolated Complex I of the electron transport chain (ETC; however, the primary defect in pink1 mutants is unclear. We tested the hypothesis that ETC deficiency is upstream of other pink1-associated phenotypes. We expressed Saccaromyces cerevisiae Ndi1p, an enzyme that bypasses ETC Complex I, or sea squirt Ciona intestinalis AOX, an enzyme that bypasses ETC Complex III and IV, in pink1 mutant Drosophila and find that expression of Ndi1p, but not of AOX, rescues pink1-associated defects. Likewise, loss of function of subunits that encode for Complex I-associated proteins displays many of the pink1-associated phenotypes, and these defects are rescued by Ndi1p expression. Conversely, expression of Ndi1p fails to rescue any of the parkin mutant phenotypes. Additionally, unlike pink1 mutants, fly parkin mutants do not show reduced enzymatic activity of Complex I, indicating that Ndi1p acts downstream or parallel to Pink1, but upstream or independent of Parkin. Furthermore, while increasing mitochondrial fission or decreasing mitochondrial fusion rescues mitochondrial morphological defects in pink1 mutants, these manipulations fail to significantly rescue the reduced enzymatic activity of Complex I, indicating that functional defects observed at the level of Complex I enzymatic activity in pink1 mutant mitochondria do not arise from morphological defects. Our data indicate a central role for Complex I dysfunction in pink1-associated defects, and our genetic analyses with heterologous ETC enzymes suggest that Ndi1p-dependent NADH dehydrogenase activity largely acts downstream of, or in parallel to, Pink1 but upstream of Parkin and mitochondrial remodeling.

Highlights: • Rescue effect was observed in both irradiated and HeLa and NIH/3T3 cells. • Novel setup and procedures to separate the rescue signals and the bystander signals. • Confirmed activation of NF-κB pathway in rescue effect using activation inhibitor. • Confirmed activation of NF-κB pathway in rescue effect using anti-NF-κB p65 antibody. - Abstract: We studied the involvement of NF-κB pathway activation in the rescue effect in HeLa and NIH/3T3 cells irradiated by α particles. Firstly, upon irradiation by 5 cGy of α particles, for both cell lines, the numbers of 53BP1 foci/cell at 12 h post-irradiation were significantly smaller when only 2.5% of the cell population was irradiated as compared to 100% irradiation, which demonstrated the rescue effect. Secondly, we studied the effect of NF-κB on the rescue effect through the use of the NF-κB activation inhibitor BAY-11-7082. Novel experimental setup and procedures were designed to prepare the medium (CM) which had conditioned the bystander cells previously partnered with irradiated cells, to ensure physical separation between rescue and bystander signals. BAY-11-7082 itself did not inflict DNA damages in the cells or have effects on activation of the NF-κB response pathway in the irradiated cells through direct irradiation. The rescue effect was induced in both cell lines by the CM, which was abrogated if BAY-11-7082 was added to the CM. Thirdly, we studied the effect of NF-κB on the rescue effect through staining for phosphorylated NF-κB (p-NF-κB) expression using the anti-NF-κB p65 (phospho S536) antibody. When the fraction of irradiated cells dropped from 100% to 2.5%, the p-NF-κB expression in the cell nuclei of irradiated NIH/3T3 cells increased significantly, while that in the cell nuclei of irradiated HeLa cells also increased although not significantly. Moreover, the p-NF-κB expression in the cell nuclei of irradiated HeLa cells and NIH/3T3 cells treated with CM also increased

Nurses are often the first responders to in-hospital cardiac emergencies. A positive attitude towards cardiopulmonary resuscitation with defibrillation may contribute to early cardiopulmonary resuscitation and rapid defibrillation, which are associated with enhanced long-term survival. The aim of this study was to translate and adapt the 31-item attitudes towards cardiopulmonary resuscitation with defibrillation and the national resuscitation guidelines (ACPRD) instrument into Chinese and to evaluate its psychometric properties in a sample of Taiwanese hospital nurses. The ACPRD instrument was translated into Chinese using professional translation services. Content validity index based on five experts to refine the translated instrument. The final instrument was applied to a sample of 290 female nurses, recruited from a regional hospital in southern Taiwan, to assess its internal consistency, factor structure, and discriminative validity. The Chinese ACPRD instrument showed good internal consistency (Cronbach's alpha=0.87). Seven factors emerged from the factor analysis. The instrument showed good discriminative validity and were able to differentiate the attitudes of nurses with more experience of defibrillation or cardiopulmonary resuscitation from those with less experience. Nurses working in emergency ward or intensive care unit also showed significantly higher overall scores compared to those working in other units. The Chinese ACPRD demonstrated adequate content validity, internal consistency, sensible factor structure, and good discriminative validity. Among Chinese-speaking nurses, it may be used as a tool for assessing the effectiveness of educational programs that aim to improve their confidence in performing cardiopulmonary resuscitation with defibrillation.

Growth hormone deficiency (GHD) in children may be associated with early cardiovascular risk factors and alterations in left ventricular (LV) structure and function; data on cardiopulmonary functional capacity are lacking. Aim of the study was to evaluate the effect of GHD and growth hormone (GH) therapy on cardiopulmonary functional capacity, left and right cardiac structure and function, and body composition in children and adolescents. Prospective, case-control study. Twenty-one untrained GHD children (11.3 ± 0.8 years) underwent cardiopulmonary exercise testing, echocardiography and dual-energy x-ray absorptiometry, before and after 12 months of GH therapy. Twenty-one controls matched for sex, pubertal status, body mass index, and physical activity (PA) were evaluated at baseline and after 1 year. At baseline, GHD patients showed reduced LV mass (LVM; 63.32 ± 7.80 vs 80.44 ± 26.29 g/m2, P = 0.006), peak oxygen consumption (VO2peak; 22.92 ± 4.80 vs 27.48 ± 6.71 mL/Kg/min, P = 0.02), peak workload (80.62 ± 29.32 vs 103.76 ± 36.20 W, P = 0.02), and O2 pulse (4.93 ± 1.30 vs 7.67 ± 2.93 mL/beat, P = 0.0003), compared with controls. GHD patients also exhibited lower lean body mass (LBM 65.36 ± 7.84% vs 76.13 ± 8.23%, P controls. GH therapy resulted in a significant increase of LVM (72.01 ± 15.88, P = 0.03), VO2peak (26.80 ± 4.97; P = 0.01), peak workload (103.67 ± 32.24, P = 0.001), O2 pulse (6.64 ± 1.68, P = 0.0007), and LBM (75.36 ± 7.59%, P = 0.0001), with a reduction in FM (22.62 ± 7.73%, P = 0.001). No difference was found in either left or right ventricular function. Our results suggest that cardiac structure, body composition and cardiopulmonary functional capacity are impaired in children with untreated GHD and can be restored after short-term GH replacement therapy.

Bellamy, R.F.; DeGuzman, L.R.; Pedersen, D.C.

1984-01-01

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

Participation by a critical care nurse in an unsuccessful resuscitation can create a unique heightened level of psychological stress referred to as postcode stress, activation of coping behaviors, and symptoms of posttraumatic stress disorder (PTSD). To explore the relationships among postcode stress, coping behaviors, and PTSD symptom severity in critical care nurses after experiencing unsuccessful cardiopulmonary resuscitations and to see whether institutional support attenuates these repeated psychological traumas. A national sample of 490 critical care nurses was recruited from the American Association of Critical-Care Nurses' eNewsline and social media. Participants completed the Post-Code Stress Scale, the Brief COPE (abbreviated), and the Impact of Event Scale-Revised, which were administered through an online survey. Postcode stress and PTSD symptom severity were weakly associated ( r = 0.20, P = .01). No significant associations between coping behaviors and postcode stress were found. Four coping behaviors (denial, self-distraction, self-blame, and behavioral disengagement) were significant predictors of PTSD symptom severity. Severity of postcode stress and PTSD symptoms varied with the availability of institutional support. Critical care nurses show moderate levels of postcode stress and PTSD symptoms when asked to recall an unsuccessful resuscitation and the coping behaviors used. Identifying the critical care nurses most at risk for PTSD will inform the development of interventional research to promote critical care nurses' psychological well-being and reduce their attrition from the profession. ©2017 American Association of Critical-Care Nurses.

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

Rescuing Quadratic Inflation

CERN Document Server

Ellis, John; Sueiro, Maria

2014-01-01

Inflationary models based on a single scalar field $\\phi$ with a quadratic potential $V = \\frac{1}{2} m^2 \\phi^2$ are disfavoured by the recent Planck constraints on the scalar index, $n_s$, and the tensor-to-scalar ratio for cosmological density perturbations, $r_T$. In this paper we study how such a quadratic inflationary model can be rescued by postulating additional fields with quadratic potentials, such as might occur in sneutrino models, which might serve as either curvatons or supplementary inflatons. Introducing a second scalar field reduces but does not remove the pressure on quadratic inflation, but we find a sample of three-field models that are highly compatible with the Planck data on $n_s$ and $r_T$. We exhibit a specific three-sneutrino example that is also compatible with the data on neutrino mass difference and mixing angles.

The purpose of this study was to evaluate a rapid cardiac ultrasound assessment performed by trained non-expert sonographers integrated into the advanced cardiac life support (ACLS). This study was prospectively performed in 179 patients (104 males and 75 females) who underwent cardiopulmonary resuscitation (CPR) in an emergency department (ED) during two calendar years (2013 and 2014). Two senior doctors, who had received emergency cardiac ultrasonography training, performed cardiac ultrasound through the apical, subxiphoid, or parasternal windows. Ultrasound evaluation and pulse controls were performed simultaneously. SPSS 18.0 was used for statistical analysis. A total of 63.7% (114) of the cardiopulmonary arrest incidents occurred out of the hospital. Only 13 patients had a femoral pulse during the initial evaluation, while 166 showed no femoral pulse. Initial monitoring showed a regular rhythm in 53 patients, ventricular fibrillation in 18 patients, and no rhythms in 108 patients. The first evaluation with ultrasound detected an effective heart rate in 26 patients and ventricular fibrillation in 14 patients, while no effective heart rate was observed in 139 patients. In addition, ultrasound revealed pericardial tamponade in seven patients and right ventricular enlargement in four cases. Global hypokinesia was detected in four patients and hypovolemia was observed in another four patients. The use of real-time ultrasonography during resuscitation with real-time femoral pulse check can help facilitate the distinguishing of pea-type arrest, ascertain the cause of the arrest, infer a suitable treatment, and optimize medical management decisions regarding CPR termination.

Continuous renal replacement therapy plays an important role in emergency rescue. Currently, no continuous renal replacement therapy machine can be used under unstable conditions as the fluid flow of these machines is controlled electronically. A novel machine that can provide emergency continuous renal replacement therapy in disaster rescue is therefore needed. Based on a volumetric metering method, a prototype portable continuous blood purifier based on a volumetric metering method was developed. Basic performance tests, special environmental tests, animal experiments and clinical use of the novel machine were completed to test and verify its performance under unstable conditions. All tests completed showed that the machine met the requirements of the national industry standards with a size reduced to approximately one half of the Baxter Aquarius machine. The clearance of harmful substances by the machine described here was equal to that of the Baxter Aquarius machine and was adequate for clinical purposes. The novel prototype performed well in all situations tested and can aid rescue work on disaster sites. Copyright © 2012 S. Karger AG, Basel.

Perfusion Pressure Cerebral Infarct (PPCI) trial - the importance of mean arterial pressure during cardiopulmonary bypass to prevent cerebral complications after cardiac surgery

Background: Debilitating brain injury occurs in 1.6–5 % of patients undergoing cardiac surgery with cardiopulmonary bypass. Diffusion-weighted magnetic resonance imaging studies have reported stroke-like lesions in up to 51 % of patients after cardiac surgery. The majority of the lesions seem...... to be caused by emboli, but inadequate blood flow caused by other mechanisms may increase ischaemia in the penumbra or cause watershed infarcts. During cardiopulmonary bypass, blood pressure can be below the lower limit of cerebral autoregulation.

Intelligent systems for urban search and rescue: challenges and lessons learned

Science.gov (United States)

Jacoff, Adam; Messina, Elena; Weiss, Brian A.

2003-09-01

Urban search and rescue (USAR) is one of the most dangerous and time-critical non-wartime activities. Researchers have been developing hardware and software to enable robots to perform some search and rescue functions so as to minimize the exposure of human rescue personnel to danger and maximize the survival of victims. Significant progress has been achieved, but much work remains. USAR demands a blending of numerous specialized technologies. An effective USAR robot must be endowed with key competencies, such as being able to negotiate collapsed structures, find victims and assess their condition, identify potential hazards, generate maps of the structure and victim locations, and communicate with rescue personnel. These competencies bring to bear work in numerous sub-disciplines of intelligent systems (or artificial intelligence) such as sensory processing, world modeling, behavior generation, path planning, and human-robot interaction, in addition to work in communications, mechanism design and advanced sensors. In an attempt to stimulate progress in the field, reference USAR challenges are being developed and propagated worldwide. In order to make efficient use of finite research resources, the robotic USAR community must share a common understanding of what is required, technologically, to attain each competency, and have a rigorous measure of the current level of effectiveness of various technologies. NIST is working with partner organizations to measure the performance of robotic USAR competencies and technologies. In this paper, we describe the reference test arenas for USAR robots, assess the current challenges within the field, and discuss experiences thus far in the testing effort.

In this study, we investigated the impact of inoculating stage, medium type and concentration of plant growth regulators on embryo rescue effectiveness by L25(5)6 orthogonal design using selfed ovules of Venus Seedless as the testing material. The main results were as follows. The most important factor influencing ovule germination was inoculating stage. Ovule germinating rate gradually increased as inoculating being postponed. The highest germinating rate appeared when inoculation was done 55d after flowering. Other influencing factors were IBA concentration, exogenous amino acid, 6-BA concentration, GA3 concentration and medium type in descending order. The best embryo rescue result was based on Nitsch medium including 1.0 mg/L IBA, 0.1 mg/L GA3, 0.7 mg /L 6-BA and 2.0 mmol/L glutamine using ovules inoculated 55d after flowering. The highest germinating rate reached 41.25%, and a batch of seedlings was also obtained. (author)

To investigate impact of prophylactic peritoneal dialysis (PD) on clinical outcomes and inflammatory cytokines in children following cardiac surgery with cardiopulmonary bypass. Prospective before-and-after nonrandomized cohort study. Pediatric cardiovascular intensive care unit in tertiary hospital. Fifty-two consecutive neonates and infants at high risk for postoperative fluid overload following cardiopulmonary bypass. All had PD catheters placed during primary cardiac surgery. Initial 27 patients were managed with passive peritoneal drainage and diuretics (controls). Following 25 patients were started on prophylactic PD in immediate postoperative period and managed per PD protocol (+PD). Cumulative fluid balance, indices of disease severity, and clinical outcomes were prospectively collected. Plasma interleukin-6 and interleukin-8 were measured immediately before-and-after cardiopulmonary bypass and at 24 and 48 hours post-cardiopulmonary bypass. Demographics, diagnoses, and intraoperative variables were similar. Median net fluid balance was more negative in +PD at 24 hours, -24 mL/kg (interquartile range: -62, 11) vs. +18 mL/kg (interquartile range: -26, 11), P = .003, and 48 hours, -88 mL/kg (interquartile range: -132, -54) vs. -46 mL/kg (interquartile range: -84, -12), P = .004. +PD had median 55 mL/kg less fluid intake at 24 hours, P = .058. Peritoneal drain, urine, and chest tube output were comparable over first 24 hours. Mean inotrope score was lower in +PD at 24 hours. +PD had earlier sternal closure--24 hours (interquartile range: 20, 40) vs. 63 hours (interquartile range: 44, 72), P interquartile range: 49, 135) vs. 125 hours (interquartile range: 70, 195), P = .10. +PD experienced lower serum concentrations of interleukin-6 and interleukin-8 at 24 hours. Prophylactic PD is associated with greater net negative fluid balance, decreased inotrope requirements, and lower serum concentrations of inflammatory cytokines in the early postoperative

A 65-year-old man collapsed after he stepped out of his car after a traffic accident. Fortunately, two police officers on a routine patrol in the area were quickly on the scene and started cardiopulmonary resuscitation. A passerby noticed that the patient was in distress and that an automatic defibrillator was nearby. He attached the electrodes of the defibrillator to the chest of the patient in accordance with instructions on the defibrillator and terminated the ventricular fibrillation (200 joule, biphasic). Emergency cardiac catheterization revealed a subtotal stenosis proximally in the right coronary artery, which was successfully treated with a stent. Based on the ideal basic life support, the immediate care by emergency mobile system and coronary angioplasty with successful revascularisation the patient could be released without any neurological deficit. This case illustrates that laypersons can use automatic external defibrillator in case of cardiac resuscitation sufficiently and quickly. © Georg Thieme Verlag KG Stuttgart · New York.

Dyspnoea is a frequent presenting complaint. The assess of this symptom is problematic when its cause is unknown once the initial diagnosis tests are done. Cardiopulmonary exercise testing is an important clinical tool to evaluate dyspnoea as it provides an approach to the integrative exercise responses involving all the organ systems. This would not be possible to reflect by means of individual studies.

To determine whether real-time video communication between the first responder and a remote intensivist via Google Glass improves the management of a simulated in-hospital pediatric cardiopulmonary arrest before the arrival of the ICU team. Randomized controlled study. Children's hospital at a tertiary care academic medical center. Forty-two first-year pediatric residents. Pediatric residents were evaluated during two consecutive simulated pediatric cardiopulmonary arrests with a high-fidelity manikin. During the second evaluation, the residents in the Google Glass group were allowed to seek help from a remote intensivist at any time by activating real-time video communication. The residents in the control group were asked to provide usual care. The main outcome measures were the proportion of time for which the manikin received no ventilation (no-blow fraction) or no compression (no-flow fraction). In the first evaluation, overall no-blow and no-flow fractions were 74% and 95%, respectively. During the second evaluation, no-blow and no-flow fractions were similar between the two groups. Insufflations were more effective (p = 0.04), and the technique (p = 0.02) and rate (p Google Glass group than in the control group. Real-time video communication between the first responder and a remote intensivist through Google Glass did not decrease no-blow and no-flow fractions during the first 5 minutes of a simulated pediatric cardiopulmonary arrest but improved the quality of the insufflations and chest compressions provided.

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

Evolutionary rescue of a parasite population by mutation rate evolution.

Science.gov (United States)

Greenspoon, Philip B; Mideo, Nicole

2017-10-01

The risk of antibiotic resistance evolution in parasites is a major problem for public health. Identifying factors which promote antibiotic resistance evolution is thus a priority in evolutionary medicine. The rate at which new mutations enter the parasite population is one important predictor; however, mutation rate is not necessarily a fixed quantity, as is often assumed, but can itself evolve. Here we explore the possible impacts of mutation rate evolution on the fate of a disease circulating in a host population, which is being treated with drugs, the use of which varies over time. Using an evolutionary rescue framework, we find that mutation rate evolution provides a dramatic increase in the probability that a parasite population survives treatment in only a limited region, while providing little or no advantage in other regions. Both epidemiological features, such as the virulence of infection, and population genetic parameters, such as recombination rate, play important roles in determining the probability of evolutionary rescue and whether mutation rate evolution enhances the probability of evolutionary rescue or not. While efforts to curtail mutation rate evolution in parasites may be worthwhile under some circumstances, our results suggest that this need not always be the case. Copyright © 2017 Elsevier Inc.

Noninvasive measurement of cardiopulmonary blood volume: evaluation of the centroid method

International Nuclear Information System (INIS)

Fouad, F.M.; MacIntyre, W.J.; Tarazi, R.C.

1981-01-01

Cardiopulmonary blood volume (CPV) and mean pulmonary transit time (MTT) determined by radionuclide measurements (Tc-99m HSA) were compared with values obtained from simultaneous dye-dilution (DD) studies (indocyanine green). The mean transit time was obtained from radionuclide curves by two methods: the peak-to-peak time and the interval between the two centroids determined from the right and left-ventricular time-concentration curves. Correlation of dye-dilution MTT and peak-to-peak time was significant (r = 0.79, p < 0.001), but its correlation with centroid-derived values was better (r = 0.86, p < 0.001). CPV values (using the centroid method for radionuclide technique) correlated significantly with values derived from dye-dilution curves (r = 0.74, p < 0.001). Discrepancies between the two were greater the more rapid the circulation (r = 0.61, p < 0.01), suggesting that minor inaccuracies of dye-dilution methods, due to positioning or delay of the system, can become magnified in hyperkinetic conditions. The radionuclide method is simple, repeatable, and noninvasive, and it provides simultaneous evaluation of pulmonary and systemic hemodynamics. Further, calculation of the ratio of cardiopulmonary to total blood volume can be used as an index of overall venous distensibility and relocation of intravascular blood volume

Critical incidents during prehospital cardiopulmonary resuscitation: what are the problems nobody wants to talk about?

Science.gov (United States)

Hohenstein, Christian; Rupp, Peter; Fleischmann, Thomas

2011-02-01

We wanted to identify incidents that led or could have led to patient harm during prehospital cardiopulmonary resuscitation. A nationwide anonymous and Internet-based critical incident reporting system gave the data. During a 4-year period we received 548 reports of which 74 occurred during cardiopulmonary resuscitation. Human error was responsible for 85% of the incidents, whereas equipment failure contributed to 15% of the reports. Equipment failure was considered to be preventable in 61% of all the cases, whereas incidents because of human error could have been prevented in almost all the cases. In most cases, prevention can be accomplished by simple strategies with the Poka-Yoke technique. Insufficient training of emergency medical service physicians in Germany requires special attention. The critical incident reports raise concerns regarding the level of expertize provided by emergency medical service doctors.

Ensemble-based computational approach discriminates functional activity of p53 cancer and rescue mutants.

Directory of Open Access Journals (Sweden)

Full Text Available The tumor suppressor protein p53 can lose its function upon single-point missense mutations in the core DNA-binding domain ("cancer mutants". Activity can be restored by second-site suppressor mutations ("rescue mutants". This paper relates the functional activity of p53 cancer and rescue mutants to their overall molecular dynamics (MD, without focusing on local structural details. A novel global measure of protein flexibility for the p53 core DNA-binding domain, the number of clusters at a certain RMSD cutoff, was computed by clustering over 0.7 µs of explicitly solvated all-atom MD simulations. For wild-type p53 and a sample of p53 cancer or rescue mutants, the number of clusters was a good predictor of in vivo p53 functional activity in cell-based assays. This number-of-clusters (NOC metric was strongly correlated (r(2 = 0.77 with reported values of experimentally measured ΔΔG protein thermodynamic stability. Interpreting the number of clusters as a measure of protein flexibility: (i p53 cancer mutants were more flexible than wild-type protein, (ii second-site rescue mutations decreased the flexibility of cancer mutants, and (iii negative controls of non-rescue second-site mutants did not. This new method reflects the overall stability of the p53 core domain and can discriminate which second-site mutations restore activity to p53 cancer mutants.
