Abstract
Background Traumatic cardiac arrest (TCA) remains a challenging problem in terms of diagnosis and management. This is due to difficulty distinguishing the TCA cause and therefore understanding the pathophysiology. The goal of this study was to analyze a contemporary series of TCA patients and classify the causes of TCA into exsanguination (EX) arrest and non-exsanguination (non-EX) arrest. Methods This was a retrospective review of patients suffering TCA during 2019 at a level I trauma center. We excluded patients whose arrests were from medical causes such as ventricular fibrillation, ventricular tachycardia, pulmonary embolus, etc., hanging, drowning, thermal injury, outside transfer, and pediatric patients (age <13 as this is our institutional definition for pediatric trauma patients). We reviewed pre-hospital run-sheets, hospital charts including autopsy findings, and classified patients into EX and non-EX TCA. We defined a witnessed arrest (WA) using the traditional outside hospital cardiac (non-trauma) arrest definition. Outcomes included the incidence of EX arrest, survival to discharge, and hospital costs. Descriptive statistics were used. Significance was set at p < 0.05. Results After exclusion, 54 patients suffered TCA with a mean age of 45.9 (±19.8) years. Eighty-three percent of patients were male. The average cost per TCA was ~$16,000. Of the 54 TCAs, 26 (48%) were WA, with one (1.85%) survivor (no non-WA TCA patients survived). Twenty-two (41%) patients died from EX-arrest; 59% penetrating vs. 28% blunt (p = 0.03). The one EX-arrest survivor was a 19-year-old gunshot wound to the leg whose arrest was witnessed, with a short downtime, and the cause of arrest (bleeding leg wound) was quickly reversible. Conclusion We classified 41% of TCAs to have died from EX-arrest with only a 1.85% survival rate. This study calls for a TCA pre-hospital registry with accurate and consistent data definitions and collection. The registry should capture the cause of arrest for future research, management decision-making, and prognostication.

Abstract
Background Historically, resuscitation in traumatic cardiac arrest (TCA) has been deemed futile. However, recent literature reports improved but varying survival. Current European guidelines emphasise the addressing of reversible aetiologies in TCA and propose that a resuscitative thoracotomy may be performed within 15 min from last sign of life. To improve clinician understanding of which patients benefit from resuscitative efforts we aimed to describe the characteristics and 30-day survival for traumatic cardiac arrest at a Swedish trauma centre with a particular focus on resuscitative thoracotomy. Methods Retrospective cohort study of adult patients (≥ 15 years) with TCA managed at Karolinska University Hospital Solna between 2011 and 2020. Trauma demographics, intra-arrest factors, lab values and procedures were compared between survivors and non-survivors. Results Among the 284 included patients the median age was 38 years, 82.2% were male and 60.5% were previously healthy. Blunt trauma was the dominant injury in 64.8% and median Injury Severity Score (ISS) was 38. For patients with a documented arrest rhythm, asystole was recorded in 39.2%, pulseless electric activity in 24.8% and a shockable rhythm in 6.8%. Thirty patients (10.6%) survived to 30 days with a Glasgow Outcome Scale score of 3 (n = 23) or 4 (n = 7). The most common causes of death were haemorrhagic shock (50.0%) and traumatic brain injury (25.5%). Survivors had a lower ISS (P < 0.001), more often had reactive pupils (P < 0.001) and a shockable rhythm (P = 0.04). In the subset of prehospital TCA, survivors less frequently received adrenaline (epinephrine) (P < 0.001) and in lower amounts (P = 0.02). Of patients that underwent resuscitative thoracotomy (n = 101), survivors (n = 12) had a shorter median time from last sign of life to thoracotomy (P = 0.03), however in four of these survivors the time exceeded 15 min. Conclusion Survival after TCA is possible. Determining futility in TCA is difficult and this study demonstrates survivors outside of recent guidelines.

Abstract
Background: This study proposed an algorithm to improve resuscitation outcomes in the emergency department (ED) for patients with traumatic out-of-hospital cardiac arrest (TOHCA). We also performed a retrospective chart review of patient outcomes before and after implementing the algorithm and sought to define factors that might influence patient outcomes. Methods: In September 2018, we implemented an algorithm for patients with TOHCA. This algorithm rapidly identifies possible causes of TOHCA and recommends appropriate interventions. We retrospectively reviewed the outcomes of all patients with TOHCA during a five-year period (comprising periods before and after the algorithm) and compared the results before and after the implementation of the algorithm. Results: After this algorithm was implemented, the use of the ED interventions of blood transfusion, placement of a large-bore central venous catheter, and thoracostomy increased significantly. The rate of return of spontaneous circulation (ROSC) also increased (before vs. after: ROSC: 23.6% vs. 41.5%, P = 0.035). Regarding hospital admission and survival to hospital discharge, we observed the trend of increment (hospital admission: 18.2% vs. 24.6%, P = 0.394; survival to hospital discharge: 0.0% vs. 4.6%, P = 0.107). Admitted patients exhibited a higher end-tidal CO2 level during resuscitation than nonadmitted patients [admitted vs. nonadmitted: 41.5 (33.3-52.0) vs. 12.0 (7.5-18.8), P = 0.001]. Conclusion: Our algorithm prioritizes the three major treatable causes of TOHCA: impedance of venous return, hypovolemia, and hypoxia. We found that rate of ROSC increased with the increasing implementation of the ED interventions recommended by the algorithm.

Abstract
OBJECTIVE There is an increase in Emergency Department (ED) utilization globally. Understanding what patients present to EDs with is important for resource allocation, training and staffing purposes. There is paucity of data pertaining to ED visit presentations in Lebanon. This study aims at describing the spectrum of diseases among adult patients who present to a tertiary care center in Lebanon, an upper-middle income country (UMIC). METHODS A retrospective chart review of adult patients (age ≥ 19) presenting to a tertiary care hospital ED during 2010-2011 was completed. Common diagnoses in three categories (all adult visits, treat and release, admitted visits) were assessed. Diagnoses were classified according to the Clinical Classifications Software. Descriptive statistics were presented in tables as frequencies and percentages. RESULTS During the study period, 32787 adults presented to the ED with 18.7% resulting in hospital admission. The most common diagnoses in ED patients were injuries and conditions due to external causes, abdominal pain, non-specific chest pain and intestinal infections. In the treat and release group, intestinal infections emerged in the common list for ages 19-44. Coronary atherosclerosis was common in admitted patients aged ≥45 years. Summer was the busiest season, with abdominal pain and intestinal infection being prominent diagnoses during that season. CONCLUSIONS This study is the first to assess adult ED visits in a Lebanese setting. Our study suggests that patients in our population suffer from the double burden of both communicable and non-communicable disease, with coronary atherosclerosis common in admitted patients (≥ 45 years) and intestinal infections common in treat and release adult patients (19-44years), the latter condition peaking in summer and driving seasonal surges in ED visits.

Abstract
BACKGROUND Advancement in trauma care has led to the evolution of emergency resuscitative thoracotomy (ERT) for the revival of trauma patients. We now have more precise understanding of selecting suitable patients for achieving optimal outcomes. The aim of our study was to analyze the utilization and survival trends during the past 5 years, as well as factors that influence survival after ERT. METHODS A 5-year (2010-2014) analysis of all trauma patients ≥18 years who underwent ERT in the American College of Surgeons Trauma Quality Improvement Program. Outcome measures were utilization rates and survival trends after ERT during the 5-year period. Regression analysis was performed. RESULTS 2229 patients underwent ERT, mean age was 37±17 years, 81% were male. Overall 56% patients had penetrating mechanism, location of major injury was thorax in 48, and 71% had signs of life (SOL) on arrival. The overall survival rate was 9.6%. From 2010-2014 ERT utilization has decreased from 331/100 000 to 243/100 000 trauma admissions (p=0.002) and the survival rate has improved from 7.9% to 11.3% (p<0.001). On regression, the independent predictors of survival were penetrating mechanism, age<60 years, SOL on arrival, no prehospital CPR and ISS. No patient aged >60 years with a blunt mechanism of injury (MOI) survived, and there were no survivors above the age of 70 years, regardless of injury mechanism. DISCUSSION Utilization of ERT has been decreased during the study period along with improved survival rates. The results of our study demonstrate that performing ERT on patients aged >60 years with a blunt MOI or on any patient aged ≥70 years, regardless of MOI, is futile and should be avoided. LEVEL OF EVIDENCE Level III, prognostic studies.

Eur J Trauma Emerg Surg 2018; 45:231-243.

Abstract
PURPOSE Emergency department thoracotomy (EDT) is a potentially life-saving procedure, performed on patients suffering traumatic cardiac arrest. Multiple indications have been reported, but overall survival remains unclear for each indication. The objective of this systematic review is to determine overall survival, survival stratified by indication, and survival stratified by geographical location for patients undergoing EDT across the world. METHODS Articles published between 2000 and 2016 were identified which detailed outcomes from EDT. All articles referring to pre-hospital, delayed, or operating room thoracotomy were excluded. Pooled odds ratios (OR) were calculated comparing differing indications. RESULTS Thirty-seven articles, containing 3251 patients who underwent EDT, were identified. There were 277 (8.5%) survivors. OR demonstrate improved survival for; penetrating vs blunt trauma (OR 2.10; p 0.0028); stab vs gun-shot (OR 5.45; p < 0.0001); signs of life (SOL) on admission vs no SOL (OR 5.36; p < 0.0001); and SOL in the field vs no SOL (OR 19.39; p < 0.0001). Equivalence of survival was demonstrated between cardiothoracic vs non-cardiothoracic injury (OR 1.038; p 1.000). Survival was worse for USA vs non-USA cohorts (OR 1.59; p 0.0012). CONCLUSIONS Penetrating injury remains a robust indication for EDT. Non-cardiothoracic cause of cardiac arrest should not preclude EDT. In the absence of on scene SOL, survival following EDT is extremely unlikely. Survival is significantly higher in the non-USA publications; reasons for this are highly complex. A UK multicentre prospective study which collects standardised data on all EDTs could provide robust evidence for better patient stratification.

Should pre-hospital resuscitative thoracotomy be reserved only for penetrating chest trauma? Eur J Trauma Emerg Surg 2018; 44:811-818.

Abstract
PURPOSE The indications for pre-hospital resuscitative thoracotomy (PHRT) remain undefined. The aim of this paper is to explore the variation in practice for PHRT in the UK, and review the published literature. METHODS MEDLINE and PUBMED search engines were used to identify all relevant articles and 22 UK Air Ambulance Services were sent an electronic questionnaire to assess their PHRT practice. RESULTS Four European publications report PHRT survival rates of 9.7, 18.3, 10.3 and 3.0% in 31, 71, 39 and 33 patients, respectively. All patients sustained penetrating chest injury. Six case reports also detail survivors of PHRT, again all had sustained penetrating thoracic injury. One Japanese paper presents 34 cases of PHRT following blunt trauma, of which 26.4% survived to the intensive therapy unit but none survived to discharge. A UK population reports a single survivor of PHRT following blunt trauma but the case details remain unpublished. Ten (45%) air ambulance services responded, each service reported different indications for PHRT. All perform PHRT for penetrating chest trauma, however, length of allowed pre-procedure down time varied, ranging from 10 to 20 min. Seventy percent perform PHRT for blunt traumatic cardiac arrest, a procedure which is likely to require aggressive concurrent circulatory support, despite this only 5/10 services carry pre-hospital blood products. CONCLUSIONS Current indications for PHRT vary amongst different geographical locations, across the UK, and worldwide. Survivors are likely to have sustained penetrating chest injury with short down time. There is only one published survivor of PHRT following blunt trauma, despite this, PHRT is still being performed in the UK for this indication.

Abstract
BACKGROUND The appropriate indications for Resuscitative Thoracotomy (RT) are still debated in the literature and various guidelines have been proposed. This study aimed to evaluate whether Advanced Trauma Life Support (ATLS) guidelines for RT were applied correctly and to evaluate the proportion of deceased patients with potentially reversible thoracic lesions (PRTL). METHODS The database at the Department of Forensic Medicine at Copenhagen University was queried for autopsy cases with thoracic lesions indicated by the SNOMED autopsy coding system. Patients were included if thoracic lesions were caused by a traumatic event with trauma team activation. Patient cases were blinded for any surgical intervention and evaluated independently by two reviewers for indications or contraindications for RT as determined by the ATLS guidelines. Second, autopsy reports were evaluated for the presence of PRTL. RESULTS Sixty-seven patients met the inclusion criteria. Two were excluded due to insufficient data. The overall agreement with guidelines was 86% and 77% for blunt and penetrating trauma, respectively. For patients submitted to RT the overall agreement with guidelines was 63% being 45% and 74% for blunt and penetrating trauma, respectively. For patients who did not undergo RT the agreement with guidelines was 100%. In all cases where RT was performed in agreement between guidelines and the clinical decision the autopsy reports showed PRTL in 16 (84%) patients. In cases of non-agreement PRTL were found in 9 (82%) patients. CONCLUSIONS Agreement with ATLS guidelines for RT was 63% for intervention and 100% for non-intervention in deceased patients with thoracic trauma. Agreement was higher for penetrating trauma than for blunt trauma. The adherence to guidelines did not improve the ability to predict autopsy findings of PRTL. Although the study has methodical limitations it represents a novel approach to the evaluation of the clinical use of RT guidelines.

Abstract
Penetrating thoracic trauma is increasing in the UK and elsewhere and immediate transfer to a Major Trauma Centre with cardio-thoracic expertise is usually optimal management. Pre-hospital traumatic cardiac arrest has an extremely poor prognosis. Performing thoracotomy before arrival in hospital has produced neurologically intact survivors in several case series. The technique described involves rapid clamshell thoracotomy and release of pericardial tamponade. Favourable outcomes appear to be associated with a single stab wound to the heart causing cardiac tamponade. Pre-hospital thoracotomy is described in the current European Resuscitation Guidelines and courses for non-surgeons are now taught at the Royal College of Surgeons of England and at the Surgical Skills Training Centre at Newcastle Freeman Hospital. It is likely that further survivors will be reported as the technique becomes more widely used. Alternatives to pre-hospital thoracotomy in the future for patients with hypovolaemic cardiac arrest may include resuscitative endovascular balloon occlusion of the aorta and pre-hospital extended preservation and resuscitation.

Abstract
Despite the establishment of evidence-based guidelines for the resuscitation of critically injured patients who have sustained cardiopulmonary arrest, rapid decisions regarding patient salvageability in these situations remain difficult even for experienced physicians. Regardless, survival is limited after traumatic cardiopulmonary arrest. One applicable, well-described resuscitative technique is the emergency department thoracotomy-a procedure that, when applied correctly, is effective in saving small but significant numbers of critically injured patients. By understanding the indications, technical details, and predictors of survival along with the inherent risks and costs of emergency department thoracotomy, the physician is better equipped to make rapid futile versus salvageable decisions for this most severely injured subset of patients.

Abstract
AIM The aim of our study was to investigate the outcome in terms of 30-day survival and to determine whether preoperative factors could predict the outcome. METHODS All patients who underwent an emergency thoracotomy (ET) during the period 2000 to 2009 were included. The patients were divided into two groups: emergency department thoracotomy and operating room thoracotomy. Data on demographics, mechanism of injury, intraoperative data, Injury Severity Scores (ISS), probability of survival, signs of life, transportation time, indications, and outcome were collected. RESULTS Forty-four ETs were performed. The mechanisms of injury were penetrating in 28 (64%) and blunt in 16 (36%) cases. In the emergency department thoracotomy group, the survival was 45 versus 20% for penetrating and blunt trauma, respectively. The total survival was 33%. In the operating room thoracotomy group, the survival was 83%. The survivors had a significantly lower ISS and a higher calculated probability of survival. The calculated mean probability of survival was 44 and 84% in the emergency department thoracotomy and operating room thoracotomy groups, respectively. The actual survival was similar, with 33% in the emergency department thoracotomy group and 83% in the operating room thoracotomy group. CONCLUSIONS The probability of survival and ISS are good predictors of survival in these patients and should be included in the future in order to make upcoming studies easier to compare. Patients with very high ISS or low probability of survival survived, justifying the procedure in our center.

Abstract
ADULTS Administer chest compressions (minimum 100/min, minimum 5 cm depth) at a ratio of 30:2 with ventilation (tidal volume 500-600 ml, inspiration time 1 s, F(I)O₂ if possible 1.0). Avoid any interruptions in chest compressions. After every single defibrillation attempt (initially biphasic 120-200 J, monophasic 360 J, subsequently with the respective highest energy), chest compressions are initiated again immediately for 2 min independent of the ECG rhythm. Tracheal intubation is the optimal method for securing the airway during resuscitation but should be performed only by experienced airway management providers. Laryngoscopy is performed during ongoing chest compressions; interruption of chest compressions for a maximum of 10 s to pass the tube through the vocal cords. Supraglottic airway devices are alternatives to tracheal intubation. Drug administration routes for adults and children: first choice i.v., second choice intraosseous (i.o.). Vasopressors: 1 mg epinephrine every 3-5 min i.v. After the third unsuccessful defibrillation amiodarone (300 mg i.v.), repetition (150 mg) possible. Sodium bicarbonate (50 ml 8.4%) only for excessive hyperkaliemia, metabolic acidosis, or intoxication with tricyclic antidepressants. Consider aminophylline (5 mg/kgBW). Thrombolysis during spontaneous circulation only for myocardial infarction or massive pulmonary embolism; during on-going cardiopulmonary resuscitation (CPR) only when indications of massive pulmonary embolism. Active compression-decompression (ACD-CPR) and inspiratory threshold valve (ITV-CPR) are not superior to good standard CPR. CHILDREN Most effective improvement of outcome by prevention of full cardiorespiratory arrest. Basic life support: initially five rescue breaths, followed by chest compressions (100-120/min depth about one third of chest diameter), compression-ventilation ratio 15:2. Foreign body airway obstruction with insufficient cough: alternate back blows and chest compressions (infants), or abdominal compressions (children >1 year). Treatment of potentially reversible causes: ("4 Hs and 4 Ts") hypoxia and hypovolaemia, hypokalaemia and hyperkalaemia, hypothermia, and tension pneumothorax, tamponade, toxic/therapeutic disturbances, thrombosis (coronary/pulmonary). Advanced life support: adrenaline (epinephrine) 10 µg/kgBW i.v. or i.o. every 3-5 min. Defibrillation (4 J/kgBW; monophasic or biphasic) followed by 2 min CPR, then ECG and pulse check. NEWBORNS: Initially inflate the lungs with bag-valve mask ventilation (p(AW) 20-40 cmH₂O). If heart rate remains <60/min, start chest compressions (120 chest compressions/min) and ventilation with a ratio 3:1. Maintain normothermia in preterm babies by covering them with foodgrade plastic wrap or similar. POSTRESUSCITATION PHASE: Early protocol-based intensive care stabilization; initiate mild hypothermia early regardless of initial cardiac rhythm [32-34°C for 12-24 h (adults) or 24 h (children); slow rewarming (<0.5°C/h)]. Consider percutaneous coronary intervention (PCI) in patients with presumed cardiac ischemia. Prediction of CPR outcome is not possible at the scene, determine neurological outcome <72 h after cardiac arrest with somatosensory evoked potentials, biochemical tests and neurological examination. ACUTE CORONARY SYNDROME: Even if only a weak suspicion of an acute coronary syndrome is present, record a prehospital 12-lead ECG. In parallel to pain therapy, administer aspirin (160-325 mg p.o. or i.v.) and clopidogrel (75-600 mg depending on strategy); in ST-elevation myocardial infarction (STEMI) and planned PCI also prasugrel (60 mg p.o.). Antithrombins, such as heparin (60 IU/kgBW, max. 4000 IU), enoxaparin, bivalirudin or fondaparinux depending on the diagnosis (STEMI or non-STEMI-ACS) and the planned therapeutic strategy. In STEMI define reperfusion strategy depending on duration of symptoms until PCI, age and location of infarction. TRAUMA: In severe hemorrhagic shock, definitive control of bleeding is the most important goal. For successful CPR of trauma patients a minimal intravascular volume status and management of hypoxia are essential. Aggressive fluid resuscitation, hyperventilation and excessive ventilation pressure may impair outcome in patients with severe hemorrhagic shock. TRAINING Any CPR training is better than nothing; simplification of contents and processes is the main aim.

Abstract
It is futile to attempt resuscitation in a blunt injury patient with no vital signs upon arriving at the emergency department. Therefore, it is recommended that resuscitation be withheld in any blunt trauma patient without vital signs while emergency medical technicians arrive at the scene of the accident. This report presents a case of a blunt torso trauma patient who lost vital signs at the scene and still received cardiopulmonary resuscitation until recovery of spontaneous circulation at the emergency department. The patient was later diagnosed with commotio cordis, and survived to be discharged without any neurological sequelae. Therefore, aggressive resuscitation should be continued until a diagnosis and differential diagnosis of blunt trauma-related cardiac arrest are made by a thorough examination in the emergency department.

A treatment protocol including vasopressin and hydroxyethyl starch solution is associated with increased rate of return of spontaneous circulation in blunt trauma patients with pulseless electrical activity.

Abstract
BACKGROUND Survival after cardiopulmonary resuscitation (CPR) using standard vasopressor therapy is disappointing. Vasopressin is a potent vasopressor that could become a useful therapeutic alternative in the treatment of cardiac arrest. AIMS The aim of this prehospital prospective cohort study was to assess the influence of treatment with vasopressin and hydroxyethyl starch solution (HHS) on outcome in resuscitated blunt trauma patients with pulseless electrical activity (PEA) cardiac arrest. METHODS Two treatment groups of resuscitated trauma patients in cardiac arrest were compared: in the epinephrine group patients received epinephrine 1 mg IV every 3 min only; in the vasopressin group patients first received hypertonic HHS and arginine vasopressin 40 units IV only or followed by epinephrine 1 mg every 3 min until cessation of CPR. Medical trauma care was provided according to advanced trauma life support (ATLS) guidelines. RESULTS The study included 31 patients and there were no significant demographic or clinical differences between the treatment groups. Significantly more circulatory restorations [11/13 (85%) vs 3/18 (17%); P < 0.01] and better 24-h survival rates [8/13 (62%) vs 2/18 (11%); P = 0.001] were observed in the vasopressin group. Average mean arterial pressure (100.4 +/- 11.4 mmHg vs 80.3 +/- 12.4 mmHg) and final end-tidal partial pressure of carbon dioxide (PETCO(2)) at admission (4.5 +/- 0.9 kPa vs 2.8 +/- 0.4 kPa) were also higher in the vasopressin group. CONCLUSION Our results suggest that victims of severe blunt trauma with PEA should be initially treated with vasopressin in combination with HHS volume resuscitation followed by standard resuscitation therapy and other procedures when appropriate. Vasopressin might be potentially lifesaving in blunt trauma cardiac arrest compared to standard treatment with epinephrine.

Abstract
OBJECTIVE Accepted guidelines define when to terminate unsuccessful resuscitations. We examined whether such resuscitations last longer for transported arrests in the field compared with those occurring in the emergency department (ED). METHODS This was a retrospective study of patients who died in an urban, academic ED over 32 months starting from January 2001. Total length of resuscitation and the interval occurring in-ED were compared for arrests in the ED and transported arrests from the field. RESULTS A total of 132 patients met the criteria, of whom 71 (53.8%) arrested in the field. Mean overall resuscitation times were longer for arrests occurring in the field (44 minutes; 95% confidence interval [CI], 39-48) compared with those in the ED (19 minutes; 95% CI, 16-22; P < .001). Mean resuscitation intervals occurring in the ED were no different for arrests occurring in the field (16 minutes; 95% CI, 13-19) than in the ED (19 minutes; 95% CI, 16-22; P > .05). CONCLUSIONS Unsuccessful resuscitations were longer and beyond guideline recommendations when arrests occurred in the field and were transported. The interval of resuscitation that occurred in the ED was the same whether or not prehospital resuscitation occurred.

Abstract
We report a case of blunt trauma leading to pulseless electrical activity (PEA) cardiac arrest that was successfully managed with emergency department thoracotomy. While the literature suggests an almost universally poor outcome from this clinical situation, in this case the patient survived with full neurological recovery. Several factors were present in this case, which have been reported as indicating an increased chance of good outcome. These were an arrest rhythm of sinus-based PEA, non-dilated reactive pupils and a short period of cardiopulmonary resuscitation. The case illustrates that in certain circumstances, emergency thoracotomy may not be futile after blunt trauma causing cardiac arrest.

Abstract
BACKGROUND Induction of profound hypothermia for emergency preservation and resuscitation (EPR) of trauma victims who experience exsanguination cardiac arrest may allow survival from otherwise-lethal injuries. Previously, we achieved intact survival of dogs from 2 hours of EPR after rapid hemorrhage. We tested the hypothesis that EPR would achieve good outcome if prolonged hemorrhage preceded cardiac arrest. METHODS AND RESULTS Two minutes after cardiac arrest from prolonged hemorrhage and splenic transection, dogs were randomized into 3 groups (n=7 each): (1) the cardiopulmonary resuscitation (CPR) group, resuscitated with conventional CPR, and the (2) EPR-I and (3) EPR-II groups, both of which received 20 L of a 2 degrees C saline aortic flush to achieve a brain temperature of 10 degrees C to 15 degrees C. CPR or EPR lasted 60 minutes and was followed in all groups by a 2-hour resuscitation by cardiopulmonary bypass. Splenectomy was then performed. The CPR dogs were maintained at 38.0 degrees C. In the EPR groups, mild hypothermia (34 degrees C) was maintained for either 12 (EPR-I) or 36 (EPR-II) hours. Function and brain histology were evaluated 60 hours after rewarming in all dogs. Cardiac arrest occurred after 124+/-16 minutes of hemorrhage. In the CPR group, spontaneous circulation could not be restored without cardiopulmonary bypass; none survived. Twelve of 14 EPR dogs survived. Compared with the EPR-I group, the EPR-II group had better overall performance, final neurological deficit scores, and histological damage scores. CONCLUSIONS EPR is superior to conventional CPR in facilitating normal recovery after cardiac arrest from trauma and prolonged hemorrhage. Prolonged mild hypothermia after EPR was critical for achieving intact neurological outcomes.

Abstract
Medical futility has a long history going back to Plato but continues to be a controversial topic. Patients, families, and health professionals are faced with decisions about which treatments and interventions may be futile, but such questions as who decides; how do competing values get resolved; what value is placed on human life; how are decisions balanced according to reason and, in some circumstances, faith; and who decides effect, benefit, and burdens of treatments are often difficult to answer. The naïve reality of medical futility is explored in the natural attitude to expose presumptions and facts related to both physiologic (fact-based) and evaluative (value-based) futility components. Highlights from the bioethical and clinical literature, a review of 3 landmark cases, and implications for nursing practice are presented. This natural attitude description could serve as what ought to be bracketed for a future phenomenology.

Abstract
Fatality Analysis Reporting System (FARS) data from 1977 to 2002 record a decreasing number of traffic fatalities taken to a hospital compared with traffic fatalities not taken to a hospital. In this study, we calculated the proportions of decedents reportedly taken to a hospital each year in each state, and the proportions surviving at least 1h. We also used death certificate data from the National Center for Health Statistics (NCHS) for 1979-1999 to categorize the proportion of motor vehicle fatalities in each state by hospital patient status. The annual number of traffic fatalities decreased slightly over the period of observation. The proportion of decedents recorded in FARS as transported to a hospital fell from about 73 to 43%. However, this proportion decreased abruptly at certain times in some states, suggesting previous misclassification. The proportion surviving at least 1h remained relatively constant. NCHS data showed a decline in the proportion declared dead in hospitals from 62 to 51%, including a decline in the proportion declared dead on arrival (DOA) from 20 to 8%. Along with occasional misclassification in some states, the decrease in cases transported only to be pronounced DOA could explain why FARS data show a decrease in deaths after hospital transport.
