Abstract
We present the case of a 10-year-old previously healthy male who suffered an out-of-hospital cardiac arrest because of abdominal trauma and survived with excellent neurologic outcomes and near complete return to baseline functional status at hospital discharge. The rapid response and efficient mobilization of resources led to an excellent patient outcome despite the severity of injuries, including intra-abdominal injuries with expected mortality, out-of-hospital traumatic arrest, coagulopathy, and an extended pediatric intensive care unit stay. This case underscores the significance of timely advanced trauma life support interventions, especially early blood product administration, efficient transport, and airway management, while sharing a remarkable case of out-of-hospital pediatric traumatic arrest with near full recovery.

Abstract
OBJECTIVE Despite the value of out-of-hospital Termination of Resuscitation (TOR) and the scientific evidence in favor of this practice, TOR has not been uniformly adopted or consistently practiced in EMS systems. Previous focus group studies have identified multiple barriers to implementation of out of hospital TOR but existing literature on EMS provider perceptions is limited. We sought to identify EMS providers' perceived barriers to performing out-of-hospital TOR in a large urban EMS system. METHODS The Chicago EMS System is a regional collaborative of EMS physicians, nurses and provider agencies, including the Chicago Fire Department (CFD), which provides exclusive emergency response for 9-1-1 calls in Chicago. CFD is an urban, fire-based EMS agency with a tiered response, with fire-fighter EMTs and paramedics providing initial care, and single role paramedics providing supplemental care and transport. A 2-page written survey was distributed to understand providers' experiences with managing OHCA and perceived barriers to TOR to inform subsequent improvements in protocol development and education. RESULTS Of 3500 EMS providers that received the survey, 2309 were completed (66%). Survey respondent demographics were fire-fighter/EMTB (69%), fire-fighter/paramedic (14%), and single role paramedic (17%). The most frequent barrier to field TOR was scene safety (86%). The most common safety issue identified was family reaction to TOR (68%) and many providers felt threatened by family when trying to perform TOR (38%). Providers with a higher career numbers of OHCA were more likely to have felt threatened by the family (OR 6.70, 95% CI 2.99-15.00) and single role paramedics were more likely than FF/EMTBs to have felt threatened (OR 3.34, 95% CI 2.65-4.22). Barriers to delivering a death notification after TOR, include being uncomfortable or threatened with possible family reaction (52%) and family asking to continue the resuscitation (45%). There was lack of formal prior death notification training, the majority learned from colleagues through on the job training. CONCLUSIONS Our study identifies scene safety, death notification delivery, and lack of formal training in death notification as barriers that EMS providers face while performing TOR in a large urban EMS system. These findings informed educational and operational initiatives to overcome the identified provider level issues and improve compliance with TOR policies.

Scand J Trauma Resusc Emerg Med 2016; 24:144.

Abstract
Background Only a small number of patients survive out-of-hospital-cardiac-arrest (OHCA). The duration of CPR varies considerably and transportation of patients under CPR is often unsuccessful. Termination-of-resuscitation (TOR)-criteria aim to preclude futile resuscitation efforts. Our goal was to find out to which extent existing TOR-criteria can be transferred to paediatric OHCA-patients with special regard to their prognostic value. Methods We performed a retrospective analysis of an eleven-year single centre patient cohort. 43 paediatric patients admitted to our institution after emergency-medical-system (EMS)-confirmed OHCA from 2003 to 2013 were included. Morrison’s BLS- and ALS-TOR-rules as well as the Trauma-TOR-criteria by the American Association of EMS Physicians were evaluated for application in children, by calculating sensitivity, specificity, negative and positive predictive value for death-, as well as survival-prediction in our cohort. Results 26 patients achieved ROSC and 14 were discharged alive (n = 7 PCPC 1/2, n = 7 PCPC 5). Sensitivity for BLS-TOR-criteria predicting death was 48.3%, specificity 92.9%, the PPV 93.3% and the NPV 46.4%. ALS-TOR-criteria for death had a sensitivity of 10.3%, specificity of 100%, a PPV of 100% and an NPV of 35%. Conclusion Retrospective application of the BLS-TOR-rule in our patient cohort identified the resuscitation of one later survivor as futile. ALS-TOR-criteria did not give false predictions of death. The proportion of CPRs that could have been abandoned is 48.2% for the BLS-TOR and only 10.3% for the ALS-TOR-rule. Both rules therefore appear not to be transferable to a paediatric population.

Abstract
The death of a child in the emergency department (ED) is one of the most challenging problems facing ED clinicians. This revised technical report and accompanying policy statement reaffirm principles of patient- and family-centered care. Recent literature is examined regarding family presence, termination of resuscitation, bereavement responsibilities of ED clinicians, support of child fatality review efforts, and other issues inherent in caring for the patient, family, and staff when a child dies in the ED. Appendices are provided that offer an approach to bereavement activities in the ED, carrying out forensic responsibilities while providing compassionate care, communicating the news of the death of a child in the acute setting, providing a closing ritual at the time of terminating resuscitation efforts, and managing the child with a terminal condition who presents near death in the ED.

Abstract
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.

Abstract
OBJECTIVE Hemorrhage is responsible for most deaths that occur during the first few hours after trauma. Animal models of trauma have shown that restricting fluid administration can reduce the risk of death; however, studies in patients are difficult to conduct due to logistical and ethical problems. To maximize the value of the existing evidence, we performed a meta-analysis to compare liberal versus restricted fluid resuscitation strategies in trauma patients. DATA SOURCES Medline and Embase were systemically searched from inception to February 2013. STUDY SELECTION We selected randomized controlled trials and observational studies that compared different fluid administration strategies in trauma patients. There were no restrictions for language, population, or publication year. DATA EXTRACTION Four randomized controlled trials and seven observational studies were identified from 1,106 references. One of the randomized controlled trials suffered from a high protocol violation rate and was excluded from the final analysis. DATA SYNTHESIS The quantitative synthesis indicated that liberal fluid resuscitation strategies might be associated with higher mortality than restricted fluid strategies, both in randomized controlled trials (risk ratio, 1.25; 95% CI, 1.01-1.55; three trials; I(2), 0) and observational studies (odds ratio, 1.14; 95% CI, 1.01-1.28; seven studies; I(2), 21.4%). When only adjusted odds ratios were pooled for observational studies, odds for mortality with liberal fluid resuscitation strategies increased (odds ratio, 1.19; 95% CI, 1.02-1.38; six studies; I(2), 26.3%). CONCLUSIONS Current evidence indicates that initial liberal fluid resuscitation strategies may be associated with higher mortality in injured patients. However, available studies are subject to a high risk of selection bias and clinical heterogeneity. This result should be interpreted with great caution.

Abstract
BACKGROUND Several studies recommend not initiating advanced life support in traumatic cardiac arrest (TCA), mainly owing to the poor prognosis in several series that have been published. This study aimed to analyze the survival of the TCA in our series and to determine which factors are more frequently associated with recovery of spontaneous circulation (ROSC) and complete neurologic recovery (CNR). METHODS This is a cohort study (2006-2009) of treatment benefits. RESULTS A total of 167 TCAs were analyzed. ROSC was obtained in 49.1%, and 6.6% achieved a CNR. Survival rate by age groups was 23.1% in children, 5.7% in adults, and 3.7% in the elderly (p < 0.05). There was no significant difference in ROSC according to which type of ambulance arrived first, but if the advanced ambulance first, 9.41% achieved a CNR, whereas only 3.7% if the basic ambulance first. We found significant differences between the response time and survival with a CNR (response time was 6.9 minutes for those who achieved a CNR and 9.2 minutes for those who died). Of the patients, 67.5% were in asystole, 25.9% in pulseless electrical activity (PEA), and 6.6% in VF. ROSC was achieved in 90.9% of VFs, 60.5% of PEAs, and 40.2% of those in asystole (p < 0.05), and CNR was achieved in 36.4% of VFs, 7% of PEAs, and 2.7% of those in asystole (p < 0.05). The mean (SD) quantity of fluid replacement was greater in ROSC (1,188.8 [786.7] mL of crystalloids and 487.7 [688.9] mL of colloids) than in those without ROSC (890.4 [622.4] mL of crystalloids and 184.2 [359.3] mL of colloids) (p < 0.05). CONCLUSION In our series, 6.6% of the patients survived with a CNR. Our data allow us to state beyond any doubt that advanced life support should be initiated in TCA patients regardless of the initial rhythm, especially in children and those with VF or PEA as the initial rhythm and that a rapid response time and aggressive fluid replacement are the keys to the survival of these patients. LEVEL OF EVIDENCE Therapeutic study, level IV; epidemiologic study, level III.

Abstract
INTRODUCTION Out-of-hospital cardiac arrest (OHCA) is a lethal health problem that affects between 236,000 and 325,000 people in the United States each year. As resuscitation attempts are unsuccessful in 70-98% of OHCA cases, Emergency Medical Services (EMS) personnel often face the needs of bereaved family members. PROBLEM Decisions to continue or terminate resuscitation at OHCA are influenced by factors other than patient clinical characteristics, such as EMS personnel's knowledge, attitudes, and beliefs regarding family emotional preparedness. However, there is little research exploring how EMS personnel care for bereaved family members, or how they are affected by family dynamics and the emotional contexts. The aim of this study is to analyze EMS personnel's experiences of caring for families when patients suffer cardiac arrest and sudden death. METHODS The study is based on a hermeneutic lifeworld approach. Qualitative interviews were conducted with 10 EMS personnel from an EMS agency in southern Sweden. RESULTS The EMS personnel interviewed felt responsible for both patient care and family care, and sometimes failed to prioritize these responsibilities as a result of their own perceptions, feelings and reactions. Moving from patient care to family care implied a movement from well-structured guidance to a situational response, where the personnel were forced to balance between interpretive reasoning and a more direct emotional response, at their own discretion. With such affective responses in decision-making, the personnel risked erroneous conclusions and care relationships with elements of dishonesty, misguided benevolence and false hopes. The ability to recognize and respond to people's existential questions and needs was essential. It was dependent on the EMS personnel's balance between closeness and distance, and on their courage in facing the emotional expressions of the families, as well as the personnel's own vulnerability. The presence of family members placed great demands on mobility (moving from patient care to family care) in the decision-making process, invoking a need for ethical competence. CONCLUSION Ethical caring competence is needed in the care of bereaved family members to avoid additional suffering. Opportunities to reflect on these situations within a framework of care ethics, continuous moral education, and clinical ethics training are needed. Support in dealing with personal discomfort and clear guidelines on family support could benefit EMS personnel.

Abstract
AbstractIntroduction:Paramedics often are asked to care for patients at the end of life. To do this, they must communicate effectively with family and caregivers, understand their legal obligations, and know when to withhold unwanted interventions. The objectives of this study were to ascertain paramedics' attitudes toward end-of-life (EOL) situations and the frequency with which they encounter them; and to compare paramedics' preparation during training for a variety of EOL care skills.Methods:A written survey was administered to a convenience sample of paramedics in two cities: Denver, Colorado and Los Angeles, California. Questions addressed: (1) attitudes toward EOL decision-making in prehospital settings; (2) experience (number of EOL situations experienced in the past two years); (3) importance of various EOL tasks in clinical practice (pronouncing and communicating death, ending resuscitation, honoring advance directives (ADs)); and (4) self-assessed preparation for these EOL tasks. For each task, importance and preparation were measured using a four-point Likert scale. Proportions were compared using McNemar chi-square statistics to identify areas of under or over-preparation.Results:Two hundred thirty-six paramedics completed the survey. The mean age was 39 years (range 22–59 years), and 222 (94%) were male. Twenty percent had >20 years of experience. Almost all participants (95%; 95% CI = 91–97%) agreed that prehospital providers should honor field ADs, and more than half (59%; 95% CI = 52–65%) felt that providers should honor verbal wishes to limit resuscitation at the scene. Ninety-eight percent of the participants (95% CI = 96–100%) had questioned whether specific life support interventions were appropriate for patients who appeared to have a terminal disease. Twenty-six percent (95% CI = 20–32%) reported to have used their own judgment during the past two years to withhold or end resuscitation in a patient who appeared to have a terminal disease. Significant discrepancies between the importance in practice and the level of preparation during training for the four EOL situations included: (1) understanding ADs (75% very important vs. 40% well prepared; difference 35%: 95% CI = 26–43%); (2) knowing when to honor written ADs (90% very important vs. 59% well-prepared; difference 31%: 95% CI = 23–38%); and (3) verbal ADs (75% very important vs. 54% well-prepared, difference 21%: 95% CI = 12–29%); and (4) communicating death to family or friends (79% very important vs. 48% well prepared, difference 31%: 95% CI = 23–39%). Paramedics' preparation in EOL skills was significantly lower than that for clinical skills such as endotracheal intubation or defibrillation.Conclusions:There is a need to include more training in EOL care into prehospital training curricula, including how to verify and apply ADs, when to withhold treatments, and how to discuss death with victims' family or friends.

Abstract
It has been reported as an ethical problem within prehospital emergency care that ambulance professionals administer physiologically futile cardiopulmonary resuscitation (CPR) to patients having suffered cardiac arrest to benefit significant others. At the same time it is argued that, under certain circumstances, this is an acceptable moral practice by signalling that everything possible has been done, and enabling the grief of significant others to be properly addressed. Even more general moral reasons have been used to morally legitimize the use of futile CPR: That significant others are a type of patient with medical or care needs that should be addressed, that the interest of significant others should be weighed into what to do and given an equal standing together with patient interests, and that significant others could be benefited by care professionals unless it goes against the explicit wants of the patient. In this article we explore these arguments and argue that the support for providing physiologically futile CPR in the prehospital context fails. Instead, the strategy of ambulance professionals in the case of a sudden death should be to focus on the relevant care needs of the significant others and provide support, arrange for a peaceful environment and administer acute grief counselling at the scene, which might call for a developed competency within this field.

Abstract
BACKGROUND There are few strategies for treating patients who have suffered cardiopulmonary arrest due to blunt trauma (BT-CPA). The aim of this population-based case series observational study was to clarify the outcome of BT-CPA patients treated with a standardized strategy that included an emergency department thoracotomy (EDT) under an emergency medical service (EMS) system with a rapid transportation system. METHODS The 477 BT-CPA registry data were augmented by a review of the detailed medical records in our emergency department (ED) and action reports in the prehospital EMS records. RESULTS Of those, 76% were witnessed and 20% were CPA after leaving the scene. In all, 18% of the patients went to the intensive care unit (ICU), the transcatheter arterial embolization (TAE) room, or the operating room (OR). Only 3% survived to be discharged. Among the 363 witnessed patients-11 of whom had ventricular fibrillation (VF) as the initial rhythm, 134 exhibiting pulseless electrical activity (PEA), and 221 with asystole-13, 1, and 3%, respectively, survived to discharge. The most common initial rhythm just after collapse was not VF but PEA, and asystole increased over the 7 min after collapse. There were no differences in the interval between arrival at the hospital and the return of spontaneous circulation between the patients that survived to discharge and deceased patients in the ED, OR, TAE room, or ICU. The longest interval was 17 min. CONCLUSIONS In BT-CPA patients, a 20-min resuscitation effort and termination of the effort are thought to be relevant. The initial rhythm is not a prognostic indicator. We believe that the decision on whether to undertake aggressive resuscitation efforts should be made on a case-by-case basis.

Abstract
PURPOSE OF REVIEW Although longstanding practice in trauma care has been to provide immediate, aggressive intravenous fluid resuscitation to injured patients with presumed internal hemorrhage, recent experimental and clinical data suggest a more discriminating approach that first considers concurrent head injury, hemodynamic stability, and the presence of potentially uncontrollable hemorrhage (e.g., deep truncal injury) versus a controllable source (e.g., distal extremity wound). RECENT FINDINGS The data suggest that rapid intravenous fluid infusions could be used for patients with isolated extremity, thermal or head injury. However, intravenous fluids should be limited in conditions with potentially uncontrollable internal hemorrhage, and particularly in patients with penetrating truncal injury being transported immediately to a trauma center. Likewise, positive pressure ventilatory support should be limited with severe hemorrhage due to the secondary reductions in venous return off-setting the effects of the fluids. For trauma patients with severe bleeding, there is growing evidence for the increased use of plasma and factor VIIa, as well as tourniquets, intra-osseus devices, and evolving monitoring techniques. SUMMARY Future research efforts in trauma should focus on the timing and rate of infusions as well as the concept of infusing alternative intravenous resuscitative fluids such as hemoglobin-based oxygen carriers (HBOCs) and the use of hemostatic agents and special blood products.

Abstract
BACKGROUND & OBJECTIVES Mobile heart-lung-machines applied by percutaneous cannulation are mostly used in patients suffering from acute myocardial infarction (AMI). Whether patients with non-coronary reasons for circulatory arrest benefit of percutaneous emergency circulatory support (PECS) in the same way is still unclear. METHODS We included 22 consecutive patients who were treated by PECS during a registry period of two years. Primary study endpoint was 30-day mortality rate. RESULTS Circulatory arrest was caused by AMI in 14 patients (64%). The remaining 8 patients suffered from cardiomyopathy/myocarditis, 4; pulmonary embolism, 2; acute pulmonary failure, 1; and tumor lysis syndrome, 1. Revascularization rate was 93% in the AMI group under PECS support. Overall survival rate was 36.4% at one month: it reached 62.5% among non-coronary patients, but only 21.4% in the AMI group (P = 0.02). Weaning was possible by direct heart transplantation in two patients. Additional two patients required implantation of a left ventricular assist device. Pumpless extracorporeal lung assist was used in one case. CONCLUSION In this small retrospective study percutaneous emergency circulatory support provided sufficient hemodynamic stabilization in emergency situations. One fifth of AMI patients were saved by immediate restoration of circulation and causal treatment when other means of resuscitation failed. Higher survival rates were noted in non-coronary patients.

Emergency medical services transport decisions in posttraumatic circulatory arrest: are national practices congruent? ACTA ACUST UNITED AC 2011; 69:1154-9; discussion 1160.

Abstract
OBJECTIVE To catalog the 9-1-1 emergency medical services (EMS) transport practices for posttraumatic circulatory arrest patients (PTCAPs) in the majority of the nation's largest municipalities and to compare those practices to guidelines recommended by the National Association of EMS Physicians (NAEMSP) and American College of Surgeons Committee on Trauma (ACSCOT). METHODS A survey was conducted in 33 of the nation's largest cities primarily to determine whether or not individual EMS systems transport PTCAPs to hospitals and, if so, whether or not the initial electrocardiographic (ECG) rhythm or mechanism of injury affected those transport decisions. RESULTS All 33 cities (100%) responded. Seven (21%) indicated that EMS would transport an "asystolic blunt trauma patient" emergently or "leave the transport decision to paramedic judgment" despite NAEMSP-ACSCOT guidelines to terminate resuscitation in such cases. Likewise, 15 (46%) of the 33 EMS agencies would transport "asystolic penetrating trauma patients" emergently. Similarly, 27 (82%) would transport penetrating injury patients and 20 (61%) would transport blunt trauma patients with persistent ECG activity but no palpable pulses. However, only five systems had policies that included a minimum ECG heart rate criterion for transport, and all agencies that monitor ECG (n = 32) would transport PTCAPs found with ventricular fibrillation. CONCLUSIONS Many of the nation's highest volume EMS systems transport certain PTCAPs emergently, contrary to NAEMSP-ACSCOT guidelines to terminate resuscitative efforts in such cases. Reasons for these discrepancies should be evaluated to help better delineate applicable consensus guidelines for large urban EMS agencies.

Abstract
OBJECTIVES To identify variation in patient, event, and scene characteristics of out-of-hospital cardiac arrest (OOHCA) patients assessed by emergency medical services (EMS), and to investigate variation in transport practices in relation to documented prehospital return of spontaneous circulation (ROSC) within eight regional clinical centers participating in the Resuscitation Outcomes Consortium (ROC) Epistry-Cardiac Arrest. METHODS OOHCA patient, event, and scene characteristics were compared to identify variation in treatment and transport practices across sites. Findings were adjusted for site and standard Utstein covariates. Using logistic regression, these covariates were modeled to identify factors related to the initiation of transport without documented prehospital ROSC as well as survival in these patients. SETTING Eight US and Canadian sites participating in the ROC Epistry-Cardiac Arrest. POPULATION Persons ≥ 20 years with OOHCA who (a) received compressions or shock by EMS providers and/or received bystander AED shock or (b) were pulseless but received no EMS compressions or shock between December 2005 and May 2007. RESULTS 23,233 OOHCA cases were assessed by EMS in the defined period. Resuscitation (treatment) was initiated by EMS in 13,518 cases (58%, site range: 36-69%, p < 0.0001). Of treated cases, 59% were transported (site range: 49-88%, p < 0.0001). Transport was initiated in the absence of documented ROSC for 58% of transported cases (site range: 14-95%, p < 0.0001). Of these transported cases, 8% achieved ROSC before hospital arrival (site range: 5-21%, p < 0.0001) and 4% survived to hospital discharge (site range: 1-21%, p < 0.0001). In cases with transport from the scene initiated after documented ROSC, 28% survived to hospital discharge (site range: 18-44%, p < 0.0001). CONCLUSION Initiation of resuscitation and transport of OOHCA and the reporting of ROSC prior to transport markedly varies among ROC sites. This variation may help clarify reported differences in survival rates among sites and provide a target for identifying EMS practices most likely to enhance survival from OOHCA.

Abstract
OBJECTIVE Few developed emergency medical services (EMS) systems operate without dedicated medical direction. We describe the experience of Hamad Medical Corporation (HMC) EMS, which in 2007 first engaged an EMS medical director to develop and implement medical direction and quality assurance programs. We report subsequent changes to system performance over time. METHODS Over one year, changes to the service's clinical infrastructure were made: Policies were revised, paramedic scopes of practice were adjusted, evidence-based clinical protocols were developed, and skills maintenance and education programs were implemented. Credentialing, physician chart auditing, clinical remediation, and online medical command/hospital notification systems were introduced. RESULTS Following these interventions, we report associated improvements to key indicators: Chart reviews revealed significant improvements in clinical quality. A comparison of pre- and post-intervention audited charts reveals a decrease in cases requiring remediation (11% to 5%, odds ratio [OR] 0.43 [95% confidence interval (CI) 0.20-0.85], p = 0.01). The proportion of charts rated as clinically acceptable rose from 48% to 84% (OR 6 [95% CI 3.9-9.1], p < 0.001). The proportion of misplaced endotracheal tubes fell (3.8% baseline to 0.6%, OR 0.16 [95% CI 0.004-1.06], (exact) p = 0.05), corresponding to improved adherence to an airway placement policy mandating use of airway confirmation devices and securing devices (0.7% compliance to 98%, OR 714 [95% CI 64-29,334], (exact) p < 0.001). Intravenous catheter insertion in unstable cases increased from 67% of cases to 92% (OR 1.31 [95% CI 1.09-1.71], p = 0.004). EMS administration of aspirin to patients with suspected ischemic chest pain improved from 2% to 77% (OR 178 [95% CI 35-1,604], p < 0.001). CONCLUSIONS We suggest that implementation of a physician medical direction is associated with improved clinical indicators and overall quality of care at an established EMS system.

Abstract
PURPOSE Children requiring prehospital cardiopulmonary resuscitation (CPR) after traumatic injury have been shown to have poor survival. However, outcome of children still receiving CPR on-arrival by emergency medical service to the emergency department (ED) has not been demonstrated in a published clinical series. METHODS An 11-year retrospective analysis from a level I pediatric trauma center of the outcomes of children requiring prehospital CPR after traumatic injury was undertaken. Outcome variables were stratified by survival, death, and CPR on-arrival. RESULTS Of 169 children requiring prehospital CPR, there were 28 survivors and 141 deaths. Of 69 children requiring CPR on-arrival to the ED, there were no survivors. There were 70 females and 99 males. Mean age of survivors was 3.4 years; nonsurvivors, 8.8 years; and 4.6 years for CPR on-arrival. Thirty-nine percent of all injuries were sustained in motor vehicle collisions; 20%, motor pedestrian collisions; 19%, assaults; 7%, falls; 4%, all terrain vehicle/motorcycle/bicycle; and 4%, gunshot wounds. Forty-two percent of all patients expired in the ED, whereas 34% expired in the intensive care unit. Eighty-seven percent of CPR on-arrival patients expired in the ED. Fifty-five percent of survivors had full neurologic recovery. CONCLUSION Although mortality was extremely high for children requiring CPR in the field After traumatic injury, it was absolute for those arriving at the ED still undergoing CPR.

Abstract
INTRODUCTION The aim of this study was to clarify the outcome of patients with cardiopulmonary arrest on arrival due to penetrating trauma (PT-CPA) and to establish the treatment strategy. PATIENTS AND METHODS The clinical course of 29 patients with PT-CPA over the past 10 years was examined. We have taken three approaches to these patients: (i) an aggressive treatment strategy; (ii) an in-hospital system supporting this aggressive resuscitation; and (iii) the pre-hospital emergency medical service (EMS) system in our city. RESULTS Although the return of spontaneous circulation (ROSC) was established in 59% of patients, only 17% survived for 7 days, 14% were discharged, and 7% were neurologically intact. Of 10 patients showing pulseless electrical activity (PEA) on the scene, ROSC was established in 100% and 30% were discharged; however, of 12 patients showing asystole, ROSC was established in 33% and no patient could be discharged. There was no difference in the time interval from the arrival at the emergency department to ROSC between discharged patients and patients who died. The time interval from collapse to arrival at the emergency department in discharged patients and patients who went to the intensive care unit was shorter than that of patients who died in the emergency department with and without ROSC. CONCLUSIONS We cannot decide to give up and terminate resuscitation in any PT-CPA patients and cannot define salvageable patients. However, our data show that 30-min resuscitation is thought to be relevant and that we should not give up on resuscitation because of the time interval without ROSC after arrival at the hospital.

Abstract
BACKGROUND Despite the existence of national American Heart Association guidelines and 2 termination-of-resuscitation (TOR) rules for ceasing efforts in refractory out-of-hospital cardiac arrest, many emergency medical services agencies in the United States have adopted their own local protocols. Public policies and local perceptions may serve as barriers or facilitators to implementing national TOR guidelines at the local level. METHODS AND RESULTS Three focus groups, lasting 90 to 120 minutes, were conducted at the National Association of Emergency Medical Services Physicians meeting in January 2008. Snowball sampling was used to recruit participants. Two reviewers analyzed the data in an iterative process to identify recurrent and unifying themes. We identified 3 distinct groups whose current policies or perceptions may impede efforts to adopt national TOR guidelines: payers who incentivize transport; legislators who create state mandates for transport and allow only narrow use of do-not-resuscitate orders; and communities where cultural norms are perceived to impede termination of resuscitation. Our participants suggested that national organizations, such as the American Heart Association and American College of Emergency Physicians, may serve as potential facilitators in addressing these barriers by taking the lead in asking payers to change reimbursement structures; encouraging legislators to revise laws to reflect the best available medical evidence; and educating the public that rapid transport to the hospital cannot substitute for optimal provision of prehospital care. CONCLUSIONS We have identified 3 influential groups who will need to work with national organizations to overcome current policies or prevailing perceptions that may impede implementing national TOR guidelines.

Abstract
Cardiopulmonary arrest and trauma are two of the major epidemics of our time. In most cases, the final outcome is altered, for better or for worse, by how interventions are provided in the prehospital setting, making that venue critical for lifesaving community research efforts. In certain venues, out-of-hospital emergency medical services personnel are highly skilled at managing resuscitations and routinely operate under strict, highly scrutinized protocols, resulting in extraordinary study compliance. Larger patient enrollment derived from population-based investigations can lead to faster study completion, less selection bias, higher-powered data, and enhanced subgroup analysis. Most importantly, the concomitant training, expert protocol development, and rigid scrutiny all lead to improved patient outcomes, regardless of study intervention. For successful implementation, emergency medical services personnel should be involved in study design, and utilize routine, automated data collection. Technologies should be provided that simplify tasks and diminish confounding variables. Considering that exception to informed consent is a critical component, prospective education and involvement of the medical community, community leaders, employee groups and the media, long before protocol implementation, is essential. Such efforts should be led by respected, academically authoritative, grassroots emergency medical services medical directors and trauma chiefs, preferably those based at the main trauma centers or public receiving facilities.

Abstract
OBJECTIVES Recently, investigators described a clinical decision rule for termination of resuscitation (TOR) designed to help determine whether to terminate emergency medical services (EMS) resuscitative efforts for out-of-hospital cardiac arrests (OOHCA). The authors sought to evaluate the hypothesis that TOR would predict no survival for patients in an independent cohort of patients with OOHCA. METHODS This was a retrospective cohort analysis conducted in the state of Arizona. Consecutive, adult, OOHCA were prospectively evaluated from October 2004 through October 2006. A statewide OOHCA database utilizing Utstein-style reporting from 30 different EMS systems was used. Data were abstracted from EMS first care reports and hospital discharge records. The TOR guidelines predict that no survival to hospital discharge will occur if 1) an OOHCA victim does not have return of spontaneous circulation (ROSC), 2) no shocks are administered, and 3) the arrest is not witnessed by EMS personnel. Data were entered into a structured database. Continuous data are presented as means (+/-standard deviations [SD]) and categorical data as frequency of occurrence, and 95% confidence intervals (CIs) were calculated as appropriate. The primary outcome measure was to determine if any cohort member who met TOR criteria survived to hospital discharge. RESULTS There were 2,239 eligible patients; the study group included 2,180 (97.4%) patients for whom the data were complete; mean age was 64 (+/-11) years, and 35% were female. The majority of patients in the study group met at least one or more of the TOR criteria. A total of 2,047 (93.8%) patients suffered from cardiac arrest that was unwitnessed by EMS; 1,653 (75.8%) had an unwitnessed arrest and no ROSC. With respect to TOR, 1,160 of 2,180 (53.2%) patients met all three criteria; only one (0.09%; 95% CI = 0% to 0.5%) survived to hospital discharge. CONCLUSIONS The authors evaluated TOR guidelines in an independent, statewide OOHCA database. The results are consistent with the findings of the TOR investigation and suggest that this algorithm is a promising tool for TOR decision-making in the field.

Abstract
PURPOSE OF REVIEW The traditional approach to trauma patients with presumed internal hemorrhage has been immediate, aggressive intravenous fluid resuscitation. Recent experimental and clinical data, however, suggest a more discriminating approach that first considers concurrent head injury, hemodynamic stability and the presence of potentially uncontrollable hemorrhage (e.g. deep truncal injury) versus a controllable source (e.g. distal extremity wound) as well as the use of new techniques to inhibit bleeding and better ways to monitor the patient's condition. RECENT FINDINGS Evolving data suggest that while aggressive fluid infusions could be used for patients with isolated extremity, thermal or head injury, they should be limited in conditions with potentially uncontrollable internal hemorrhage, and particularly in patients with penetrating truncal injury being transported immediately to a trauma center. Likewise, the minute volume of positive pressure ventilatory support should be limited with potential severe hemorrhage due to the secondary reductions in venous return. For trauma patients with severe bleeding there is growing evidence for the increased use of plasma and factor VIIa, as well as tourniquets, intraosseus devices and evolving monitoring techniques. SUMMARY Owing to the growing societal threat of trauma, further research, including studies already under way, will be critical to delineate the timing and technique of infusing advantageous resuscitative fluids such as hypertonic saline and hemoglobin-based oxygen carriers as well as the use of hemostatic agents and special blood products.

Abstract
This study was conducted to assess the various ethical attitudes of emergency specialists in Korea toward resuscitation. A questionnaire investigating the following key topics concerning the ethics of resuscitation was sent to emergency specialists in Korea: when not to attempt resuscitation, when to stop resuscitation, withdrawal of life-sustaining treatment, diagnosis of death by non-physicians, permission for family members to stay with the patient during resuscitation, and teaching with the body of the recently deceased patient. We found broad variation in medical practice at patient death and in the ethical considerations held and followed by emergency physicians (EPs) during resuscitation in Korea. Initiating and concluding resuscitation attempts were practiced according to ethical and cultural norms, as well as medical conditions. Guidelines for resuscitation ethics that are based on the Korean medico-legal background need to be developed. Education of EPs to solve the ethical dilemma in resuscitation is needed.

Abstract
CONTEXT Termination of resuscitation (TOR) in the field for out-of-hospital cardiac arrest (OHCA) can reduce unnecessary transport to hospital and increase availability of resources for other patients. OBJECTIVES To compare the performance of three TOR guidelines for Basic Life Support-Defibrillator (BLS-D) providers when applied to cardiac arrest patients in the Cardiac Arrest and Resuscitation Epidemiology (CARE) study. DESIGN This prospective cohort study involved all OHCA patients attended by BLS-D providers in a large urban center. The data analyses were conducted secondarily on these prospectively collected data. Three TOR guidelines proposed by Marsden et al. [BMJ 1995;311:49-51], Petrie [CJEM 2001;3:186-92] and Verbeek et al. [Acad Emerg Med 2002;9:671-8] were applied to show the relationship between the guidelines and actual survival. RESULTS From 1 October 2001 to 14 October 2004, 2269 patients were enrolled into the study. Thirty-two (1.4%) survived to hospital discharge. For the 3 TOR guidelines, sensitivity was 93.8% (95%CI=79.9-98.3) (Petrie), 81.3% (95%CI=64.7-91.1) (Verbeek) and 90.6% (95%CI=75.8-96.8) (Marsden). Negative predictive value was 99.7% (95%CI=99.0-100.0) (Petrie), 99.6% (95%CI=99.2-99.8) (Verbeek) and 99.8% (95%CI=99.4-99.9) (Marsden). Application of these guidelines would have resulted in transport of 68.4% (Petrie), 31.3% (Verbeek) and 36.1% (Marsden) of cases. The Petrie guidelines would have recommended TOR in two patients who eventually survived. Similarly TOR was recommended in six patients for Verbeek and three patients for Marsden who eventually survived. CONCLUSION We found all three TOR guidelines to have high sensitivity and negative predictive value. However the specificity and transport rates varied greatly. Application of any TOR guidelines may be affected by local EMS and population factors which should be considered in any policy decision.

Abstract
Trauma has been perceived by the public as occurring as an isolated event, always resulting in favorable outcomes. There has therefore been a lack of discussion of futility of care and termination of care when dealing with the sick trauma patient. Several stages exist where issues of futility and early termination of care must be considered. These include the prehospital setting and involve the emergency medical service system in recognizing those patients who are nonsurvivors. Next is in the emergency room, where heroic measures may not benefit the very sick patient. In the operating room, the surgeon must always reassess and recognize when massive resuscitation will not benefit a particular trauma patient. Lastly, the intensivist must recognize those patients who may or may not benefit from continued efforts to sustain life.

Abstract
Decision making near the end of life can be complex and laden with emotion for families and health care providers. Families and patients can prepare themselves for these difficult moments by thinking ahead about the patient's wishes and preparing clear documents that express those wishes. Health care providers can prepare themselves by being familiar with those documents, considering the goals of treatment, remembering the principles on which health care ethics are founded and knowing decision-making models that will help them to think through treatment plans and the best options for patient taking into consideration the goals of treatment.

Abstract
BACKGROUND We prospectively evaluated a clinical prediction rule to be used by emergency medical technicians (EMTs) trained in the use of an automated external defibrillator for the termination of basic life support resuscitative efforts during out-of-hospital cardiac arrest. The rule recommends termination when there is no return of spontaneous circulation, no shocks are administered, and the arrest is not witnessed by emergency medical-services personnel. Otherwise, the rule recommends transportation to the hospital, in accordance with routine practice. METHODS The study included 24 emergency medical systems in Ontario, Canada. All patients 18 years of age or older who had an arrest of presumed cardiac cause and who were treated by EMTs trained in the use of an automated external defibrillator were included. The patients were treated according to standard guidelines. Characteristics of diagnostic tests for the prediction rule were calculated. These characteristics include sensitivity, specificity, and positive and negative predictive values. RESULTS Follow-up data were obtained for all 1240 patients. Of 776 patients with cardiac arrest for whom the rule recommended termination, 4 survived (0.5 percent). The rule had a specificity of 90.2 percent for recommending transport of survivors to the emergency department and had a positive predictive value for death of 99.5 percent when termination was recommended. Implementation of this rule would result in a decrease in the rate of transportation from 100 percent of patients to 37.4 percent. The addition of other criteria (a response interval greater than eight minutes or a cardiac arrest not witnessed by a bystander) would further improve both the specificity and positive predictive value of the rule but would result in the transportation of a larger proportion of patients. CONCLUSIONS The use of a clinical prediction rule for the termination of resuscitation may help clinicians decide whether to terminate basic life support resuscitative efforts in patients having an out-of-hospital cardiac arrest.

Abstract
OBJECTIVE To investigate the end-of-life decision process in patients managed by emergency physicians in the prehospital setting. DESIGN A 40-item retrospective study about most recent end-of-life decision in the prehospital setting. PATIENTS AND PARTICIPANTS 1069 physicians (44.9%) from 192 French emergency mobile units. MEASUREMENTS AND RESULTS A total of 816 (76.3%) physicians reported at least one prehospital end-of-life decision. Conscious patients were involved in 30.7% (54/176) and families in 63.6% of cases. The physician discussed the end-of-life decision with at least one other physician in 56.5% of cases. Perceived imminent death was the most frequently reported criterion (90.1%). Nearly four fifths of patients died before arrival at the hospital (78.8%). Factors independently associated with prehospital withdrawal decision included multiple trauma [odds ratio (OR) 5.7, 95% confidence interval (CI) 1.6-19.7], intubation (OR 3.9, 95% CI 2.3-6.5), chronic disease with severe heart failure (OR 2.8, 95% CI 1.5-5.2), acute event with postanoxic coma (OR 2.2, 95% CI 1.3-4.0), emergency physician from a teaching hospital (OR 2.1, 95% CI, 1.3-3.5), male patient (OR 1.9, 95% CI 1.1-3.3), and no sedation (OR 1.9, 95% CI 1.2-3.1). Prehospital withholding decisions were taken for 684 (88%) patients and withdrawing decisions for 12%. CONCLUSIONS Treatment withholding and withdrawal is common in the prehospital setting in France. These decisions remain highly questionable in this emergency context, in the absence of knowledge of the patient's medical history and of patients' and relatives' clear wishes concerning end-of-life decisions.

Abstract
STUDY OBJECTIVE Termination of resuscitation in the field for out-of-hospital cardiac arrest can reduce unnecessary transport to hospital and associated road hazards and increase availability of emergency medical services (EMS) and emergency department resources for other patients. We compare the performance of 3 termination-of-resuscitation guidelines for basic life support-defibrillator (BLS) providers when applied to cardiac arrest patients in the Ontario Prehospital Advanced Life Support study. METHODS This prospective cohort study involved all out-of-hospital cardiac arrest patients attended by BLS defibrillator providers in 21 Ontario urban or suburban communities. The data analyses were conducted secondarily on these prospectively collected data. Three termination-of-resuscitation guidelines (referred to as Marsden, Petrie, and Verbeek rules) were applied and contingency tables calculated to show the relationship between the rule and actual survival. RESULTS From 1988 to 2003, 13,684 cardiac arrest patients were attended by BLS defibrillator providers. Six hundred thirty-six (4.7%) patients survived to hospital discharge. For the 3 termination-of-resuscitation rules, sensitivity was 99.8% (95% confidence interval [CI] 99.5% to 100.0%) (Petrie rules), 99.5% (95% CI 99.0% to 100.0%) (Verbeek rules), and 99.8% (95% CI 99.5% to 100.0%) (Marsden rules). Specificity was 9.9% (95% CI 9.4% to 10.4%) (Petrie rules), 52.9% (95% CI 52.1% to 53.8%) (Verbeek rules), and 19.4 % (95% CI 18.8% to 20.1%) (Marsden rules). Negative predictive value was 99.9% (95% CI 99.8% to 100.0%) (Petrie rules), 100.0% (95% CI 99.9% to 100.0%) (Verbeek rules), and 100.0% (95% CI 99.9% to 100.0%) (Marsden rules). These rules would have resulted in field termination of resuscitation in 9.4% (Petrie rules), 50.5% (Verbeek rules), and 18.5 % (Marsden rules) of cases. Termination of resuscitation was recommended for 1 patient (Petrie rules), 3 patients (Verbeek rules), and 1 patient (Marsden rules), who survived. CONCLUSION We found all 3 termination-of-resuscitation rules to have high sensitivity and negative predictive value. However, the specificity and transport rates varied greatly. The results of this study will be useful for EMS providers considering adoption of termination of resuscitation in BLS defibrillator systems for out-of-hospital cardiac arrest.

Abstract
Most laboratory studies of cardiac arrest use models of ventricular fibrillation, but in the emergency room, operating room or intensive care unit, cardiac arrest frequently results from asphyxia. We sought to investigate the effect of different durations of asystole secondary to asphyxia on myocardial function after resuscitation. In a laboratory based experimental series, anaesthetized rats received either 4 or 8 min of asphyxial cardiac arrest, and following standardized resuscitation, serial transthoracic echocardiography was performed. Severe depression of left ventricular fractional shortening occurred in both groups with partial recovery only in the 4-min arrest group, while left ventricular end-diastolic diameter was increased in the 4-min group. The pH, HCO3(-) and SBE were reduced in both groups after resuscitation, but the degree of acidosis was greater in the 8-min group. In this model, transthoracic echocardiography demonstrated both systolic and diastolic impairment following asphyxial cardiac arrest, and a clear dose-effect relationship between duration of asphyxia and degree of impairment. A shorter duration of asphyxia was associated with a lesser increase in left ventricular end-diastolic dimension, compared with more protracted asphyxia; the shorter arrest was associated with better recovery of contractile function and acidosis. Increased duration of asphyxia causes increased systolic and diastolic dysfunction. These findings may have significant implications for resuscitative therapeutics. ECHO assessment may permit specific targeting of therapy directed towards systolic or diastolic function during CPR.

Abstract
BACKGROUND Survival for trauma patients who receive prehospital cardiopulmonary resuscitation (CPR) has been reported as poor. We assessed the survival for prehospital CPR in our trauma system and attempted to find prehospital predictors of mortality. STUDY DESIGN We conducted a retrospective review of our Level I trauma center's database that identified 588 patients over a 6-year period (January 1, 1997, to December 31, 2002) who received prehospital CPR. Mechanisms of injury, prehospital vital signs, and survival to discharge were analyzed. RESULTS Twenty-two of 588 patients (3.7%) survived to hospital discharge. Overall, 60.7% did not survive to achieve hospital admission, and an additional 32.6% died on the first hospital day. Patients with penetrating injuries had a significantly lower survival rate than those with either blunt or other (eg, drowning, hanging) injuries (0.9% versus 6.2%, and 13.2%, respectively, p < 0.001) and significantly lower Revised Trauma Scores (RTS; mean +/- SD: 0.32 +/- 0.96 versus 0.76 +/- 1.84 and 1.18 +/- 2.51, respectively, p < 0.05.) The likelihood of survival with RTS = 0 was less than 1% overall, and 0% for penetrating trauma. CONCLUSIONS These findings add support to recent guidelines regarding the termination or withholding of resuscitation for trauma patients in the prehospital setting. Victims of penetrating trauma with a prehospital RTS = 0 (combination of no respiratory rate, no systolic blood pressure, and a Glasgow Coma Score of 3) should be declared "dead at the scene."

Abstract
OBJECTIVES The purpose of this study was to assess the attitude of paramedics to on-scene termination of cardiopulmonary resuscitation (T-CPR) efforts in children prior to developing a pediatric T-CPR policy. METHODS A 26-item anonymous survey was conducted of all of the active paramedics in a large urban EMS system where T-CPR had been practiced routinely for adults. Questions addressed paramedic demographics, training level, experience with adult and pediatric advanced cardiac life support (ACLS), experience with T-CPR in adults, T-CPR case scenarios, and T-CPR in children. RESULTS All 201 paramedics in the system (mean age=34.2 years; mean years as paramedic = 8.5 ) completed all relevant items of the survey (100% compliance). Two-thirds had provided ACLS for cardiac arrest to >50 adults (93% >10 adults) and more than one-third had performed ACLS on >20 children (72% >5 children). In addition, 90% had participated in T-CPR for adults. The majority of paramedics reported at least occasional (pre-defined) difficulty with adult T-CPR including family confrontation, 43%; personal discomfort, 13%; disagreement with physician decision to continue efforts, 11%; and fear of liability, 10%. Paramedic self ratings of comfort with terminating CPR on a scale from 1 to 10 (1: very comfortable; 10: uncomfortable) for adults and children were 1 and 9, respectively (P<0.001). In addition, the clear majority (72%) responded that children deserve more aggressive resuscitative efforts than adults. CONCLUSIONS Paramedics feel relatively uncomfortable with the concept of terminating resuscitation efforts in children in the pre-hospital setting.

Abstract
OBJECTIVE To determine effective interventional targets for out-of-hospital cardiac arrests by analyzing the distribution characteristics of arrest patients according to age and sex with special emphasis on ventricular fibrillation (VF). METHODS All patients who suffered out-of-hospital cardiac arrest in Osaka Prefecture, Japan during 2 years, were prospectively recorded based on the Utstein style. The number and the incidence rate of cases of arrest, witnessed arrest, and witnessed VF were evaluated according to age and sex. The percentage of resuscitation attempts in arrest cases was also calculated. RESULTS We recorded 10139 consecutive out-of-hospital cardiac arrest cases. Resuscitation was attempted in 97.0% of 10139 and showed no significant differences by age and sex. The incidence rate of cardiac arrests increased exponentially with age. Men showed a significantly higher incidence rate of out-of-hospital arrests than women in every age group. Most of the witnessed VF cases showed cardiac a aetiology and were predominantly observed in men in their 50s, 60s and 70s. The incidence rates of witnessed VF were also greater in them. CONCLUSION Our study provides evidence that there are significant age and sex related epidemiological differences in cardiac arrests and we need to understand them better. Strategies that focus on high yielded patients, those in witnessed VF, should be pursued. These efforts should be expected to yield sex and age related differences in survivors.

Abstract
Dutiful attention to virtue, teamwork, beneficence, justice, and respect for patient autonomy provides a coherent approach to addressing many ethical dilemmas in the out-of-hospital setting. Most of the great risks of EMS--abandonment, competence, and safe-driving skills--lie at the ethike or character of those who ply the prehospital art. Proactively fostering the personal and professional virtue of team members may be a kind of moral vaccination against the ethical pitfalls inherent in emergency medical service provision. Future training, education, disaster preparedness drills, and related exercises must include opportunities for character and team building before optimal performance and accountability can be assured. In the steady, almost glacial, maturation of the specialty of EMS medicine, truly the character of those who serve in the "line of fire" of evaluation, management, and transport in the out-of-hospital arena must be girded with more than the armor and shields of technology. Since September 11, 2001, it has become increasingly clear that EMS workers must strengthen their ability to bear the "slings and arrows of outrageous fortune," armed with swords of discipline, virtue, and character to provide the breadth of care that only a well orchestrated team can deliver. Ultimately, humans perform best when they share themselves unselfconsciously, surrendering to an enterprise and cause far greater than themselves. Our citizens, patients, and heroic colleagues deserve no less.

Abstract
Recent research efforts have demonstrated that many longstanding practices for the prehospital resuscitation of trauma patients may be inappropriate under certain circumstances. For example, traditional practices, such as application of anti-shock garments and i.v. fluid administration to raise blood pressure, may even be detrimental in certain patients with uncontrolled bleeding, particularly those with penetrating injuries. ETI, although potentially capable of transiently prolonging a patient's ability to tolerate circulatory arrest, may also be harmful if overzealous PPV further compromises cardiac output, particularly in those patients with severe hemodynamic instability. In addition, if these procedures delay patient transport, any benefit that they may offer could be outweighed by the delay in definitive care. Although traditionally taught to "hyperventilate" the patient with severe head injury, current recommendations are to avoid this tactic unless there is evidence of herniation. Even time-honored traditions, such as universal spinal precautions and CPR during circulatory arrest, are being scrutinized [2,134]. Further prospective randomized clinical trials are needed to better define the role of many overlapping therapies in prehospital trauma care. Such research must specifically address and stratify the different mechanisms of injury, anatomic areas involved, and the physiologic staging of the injury. Furthermore, the efficacy of a single intervention may be masked by a confounding variable [5]. For example, a trial of an effective new HBOC in moribund patients that indicates no advantage in the study results may have been confounded by overzealous PPV, which may have led to suboptimal outcomes. It is hoped that, in the future, EMS physicians will be able to not only better discriminate in their management of patients with major trauma but also improve outcomes as a result.

Abstract
Despite all of the progress in reanimating patients in cardiac arrest over the last half century, resuscitation attempts usually fail to restore spontaneous circulation. Thus, the most common of all resuscitation decisions after initiation remains the decision to stop. An entire library of research and guidelines for terminating resuscitative efforts has been developed in the past decade. However, this most central decision is often left open to chance, provider preference, family wishes, futility judgments, and resource concerns-a host of subjective considerations at the bedside and beyond. This article sheds light on these considerations, acknowledging the pivotal role that resuscitation science and guidelines can play in the multifactorial decision to discontinue resuscitative efforts.

Abstract
The most appropriate prehospital approach to resuscitative fluid interventions for trauma patients involves: determining the mechanism of injury (i.e., blunt versus penetrating versus thermal injury); identifying anatomic involvement (i.e., truncal versus isolated head injury versus isolated extremity injury); and staging the condition (i.e., hemodynamic stability versus instability versus moribund state). Based on available data, the liberal use of fluid infusions for presumed uncontrolled internal hemorrhage, such as that usually occurring after penetrating abdominal and thoracic injuries, is no longer advised. Although some infusion might be appropriate in patients with extremely severe hemorrhage (i.e., no palpable blood pressure, unconscious), the priority in such patients is rapid evacuation to definitive surgical intervention, with airway control and intravenous access provided en route. The data are less clear for patients with blunt injuries, particularly those with closed head injury. Most researchers would still recommend that patients with isolated extremity and head injuries, either blunt or penetrating, are candidates for immediate support of blood pressure through fluid infusions. However, the addition of potential intra-abdominal, intrapelvic, or intrathoracic injuries with uncontrolled hemorrhage confounds the decision-making process. Although conventional wisdom has been to provide aggressive blood pressure support under these circumstances through judicious use of isotonic, or perhaps hypertonic, fluid resuscitation, recent experimental data challenge even this philosophy. Use of new blood substitutes might help to resolve some of these issues by providing oxygen delivery with limited volume in the face of uncontrolled hemorrhage.

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