Abstract
BACKGROUND/OBJECTIVE Traumatic cardiac arrest (TCA) is the cessation of cardiac pumping activity secondary to blunt or penetrating trauma. The aim of this study is to identify the outcomes of traumatic cardiac arrest in pediatric patients within the local community and report the causes and resuscitation management for the defined cases. METHODS This was a retrospectively conducted cohort study that took place in King Abdulaziz Medical City (KAMC) and King Abdullah Specialized Children Hospital (KASCH) from 2005 to 2021, Riyadh, Kingdom of Saudi Arabia. The study population involved pediatric patients aged 14 years or less who were admitted to our Emergency Department (ED) and had a traumatic cardiac arrest in the ED. RESULTS There were 26,510 trauma patients, and only 56 were eligible for inclusion. More than half (60.71%, n= 34) of the patients were males. Patients aged four years or less constituted 51.79% (n= 29) of the included cases. The majority of patients were Saudis (89.29%, n= 50). The majority of the patients had cardiac arrest prior to ED admission (78.57%, n= 44). The majority (89.29%, n= 50) had a GCS of 3 at ED arrival. The most frequently observed first cardiac arrest rhythm was asystole, followed by pulseless electrical activity and ventricular fibrillation, accounting for 74.55%, 23.64%, and 1.82%, respectively. CONCLUSION Pediatric TCA is high acuity. Children who experience TCA have dreadful outcomes, and survivors can suffer serious neurological impairments. We provided the experience of one of the largest trauma centers in Saudi Arabia to standardize the approach for managing TCA and, hopefully, improve its outcomes.

Paediatric traumatic out-of-hospital cardiac arrest: A systematic review and meta-analysis. Resuscitation 2020; 149:65-73. [PMID: 32070780 DOI: 10.1016/j.resuscitation.2020.01.037] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2019] [Revised: 01/19/2020] [Accepted: 01/29/2020] [Indexed: 11/20/2022]
Abstract
AIM In this study, we sought to quantitatively describe the survival outcomes, incidence rates, and predictors of survival after paediatric traumatic out-of-hospital cardiac arrest (OHCA). METHODS We systematically searched MEDLINE, EMBASE, EMCARE, and CINAHL to identify observational or interventional studies reporting relevant data for paediatric traumatic OHCA. The Joanna Briggs Institute critical appraisal tool for prognostic studies was used to assess study quality. We analysed the survival outcomes and pooled incidence rates per 100,000 person-years using random-effect models. RESULTS Nineteen articles met the eligibility criteria involving 705 Emergency Medical Service (EMS)-attended and 973 EMS-treated traumatic paediatric OHCAs across an estimated serviceable population of 15.2 million. Four studies were conducted in the Asia-pacific region, seven in Europe, and eight in North America. Nine studies were assessed as low quality. Overall pooled survival to hospital discharge or 30-day survival for the EMS-treated cases was 1.2% (n = 6 studies; 95% confidence interval (CI): 0.1%, 3.1%; I2 = 26.1%). The pooled rate of return of spontaneous circulation in four studies was 22.1% (95% CI: 18.4%, 26.1%; I2 = 0.0%), and the pooled rate of event survival was 18.8% (n = 3 studies; 95% CI: 15.2%, 22.7%; I2 = 0.0%). The pooled incidence of EMS-treated paediatric traumatic OHCA was 1.6 cases per 100,000 person-years (n = 10 studies; 95% CI: 1.1, 2.2; I2 = 98.1%). No study reported on the impact of epidemiological or clinical factors on survival. CONCLUSION Survival outcomes of paediatric traumatic OHCA are poor and existing studies report varying incidence rates. The absence of large prospective and international registry data hinders the development of novel strategies to improve survival rates.

Abstract
OBJECTIVES To develop a clinical prediction score for predicting mortality in children following return of spontaneous circulation after in-hospital cardiac arrest. DESIGN Observational study using prospectively collected data. SETTING This was an analysis using data from the Get With The Guidelines-Resuscitation registry between January 2000 and December 2015. PATIENTS Pediatric patients (< 18 yr old) who achieved return of spontaneous circulation. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS The primary outcome was in-hospital mortality. Patients were divided into a derivation (3/4) and validation (1/4) cohort. A prediction score was developed using a multivariable logistic regression model with backward selection. Patient and event characteristics for the derivation cohort (n = 3,893) and validation cohort (n = 1,297) were similar. Seventeen variables associated with the outcome remained in the final reduced model after backward elimination. Predictors of in-hospital mortality included age, illness category, pre-event characteristics, arrest location, day of the week, nonshockable pulseless rhythm, duration of chest compressions, and interventions in place at time of arrest. The C-statistic for the final score was 0.77 (95% CI, 0.75-0.78) in the derivation cohort and 0.77 (95% CI, 0.74-0.79) in the validation cohort. The expected versus observed mortality plot indicated good calibration in both the derivation and validation cohorts. The score showed a stepwise increase in mortality with an observed mortality of less than 15% for scores 0-9 and greater than 80% for scores greater than or equal to 25. The model also performed well for neurologic outcome and in sensitivity analyses for events within the past 5 years and for patients with or without a pulse at the onset of chest compressions. CONCLUSIONS We developed and internally validated a prediction score for initial survivors of pediatric in-hospital cardiac arrest. This prediction score may be useful for prognostication following cardiac arrest, stratifying patients for research, and guiding quality improvement initiatives.

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

Abstract
BACKGROUND Prehospital traumatic cardiopulmonary arrest is associated with dismal prognosis, and patients rarely survive to hospital discharge. Recently established guidelines do not apply to the pediatric population because of paucity of data. The study objective was to determine the survival of pediatric patients presenting in the field with no signs of life after blunt trauma. METHODS We conducted a retrospective analysis of the National Trauma Data Bank research data set (2002-2010). All patients 18 years and younger with blunt traumatic injuries were identified (DRG International Classification of Diseases-9th Rev. codes 800-869). No signs of life (SOL) was defined on physical examination findings and included the following: pulse, 0; respiratory rate, 0; systolic blood pressure, 0; and no evidence of neurologic activity. These same criteria were reassessed on arrival at the emergency department (ED). Furthermore, we examined patients presenting to the ED who underwent resuscitative thoracotomy (Current Procedural Terminology code 34.02). Our primary outcome was survival to discharge from the hospital. RESULTS There were a total of 3,115,597 pediatric patients who were found in the field after experiencing blunt trauma. Of those, 7,766 (0.25%) had no SOL. Seventy percent of the patients with no SOL in the field were male. Survival to hospital discharge of all patients presenting with no SOL was 4.4% (n = 340). Twenty-five percent of the patients in the field with no SOL were successfully resuscitated in the field and regained SOL by the time they arrived to the ED (n = 1,913). Of those patients who regained SOL, 13.8% (n = 265) survived to hospital discharge. For patients in the field with no SOL, survival to discharge was significantly higher in patients who did not receive a resuscitative thoracotomy than in those who did. CONCLUSION Survival of pediatric blunt trauma patients in the field without SOL is dismal. Resuscitative thoracotomy poses a heightened risk of blood-borne pathogen exposure to involved health care workers and is associated with a significantly lower survival rate. LEVEL OF EVIDENCE Prognostic study, level III; therapeutic study, level IV.

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
Advances in early recognition, effective response, and high-quality resuscitation before, during, and after cardiac arrest have resulted in improved survival for infants and children over the past 10 years. This review addresses several key factors that can make a difference in survival outcomes, including the etiology of pediatric cardiac arrests in and out of hospital, mechanisms and techniques of circulation of blood flow during cardiopulmonary resuscitation (CPR), quality of CPR, meticulous postresuscitative care, and effective training. Monitoring and quality improvement of each element in the system of resuscitation care are increasingly recognized as key factors in saving lives.

Abstract
Introduction This systematic review is focused on the in-hospital mortality and neurological outcome of survivors after prehospital resuscitation following trauma. Data were analyzed for adults/pediatric patients and for blunt/penetrating trauma. Methods A systematic review was performed using the data available in Ovid Medline. 476 articles from 1/1964 - 5/2011 were identified by two independent investigators and 47 studies fulfilled the requirements (admission to hospital after prehospital resuscitation following trauma). Neurological outcome was evaluated using the Glasgow outcome scale. Results 34 studies/5391 patients with a potentially mixed population (no information was found in most studies if and how many children were included) and 13 paediatric studies/1243 children (age ≤ 18 years) were investigated. The overall mortality was 92.8% (mixed population: 238 survivors, lethality 96.7%; paediatric group: 237 survivors, lethality 86.4% = p < 0.001). Penetrating trauma was found in 19 studies/1891 patients in the mixed population (69 survivors, lethality: 96.4%) and in 3 pediatric studies/91 children (2 survivors lethality 97.8%). 44.3% of the survivors in the mixed population and 38.3% in the group of children had a good neurological recovery. A moderate disability could be evaluated in 13.1% in the mixed population and in 12.8% in children. A severe disability was found in 29.5% of the survivors in the mixed patients and in 38.3% in the group of children. A persistent vegetative state was the neurological status in 9.8% in the mixed population and in 10.6% in children. For each year prior to 2010, the estimated log-odds for survival decreased by 0.022 (95%-CI: [0.038;0.006]). When jointly analyzing the studies on adults and children, the proportion of survivors for children is estimated to be 17.8% (95%-CI: [15.1%;20.8%]). The difference of the paediatric compared to the adult proportion is significant (p < 0.001). Conclusions Children have a higher chance of survival after resuscitation of an out-of-hospital traumatic cardiac arrest compared to adults but tend to have a poorer neurological outcome at discharge.

Abstract
OBJECTIVE To determine the epidemiology and survival of pediatric out-of-hospital cardiac arrest (OHCA) secondary to trauma. METHODS The CanAm Pediatric Cardiac Arrest Study Group is a collaboration of researchers in the United States and Canada sharing a common goal to improve survival outcomes for pediatric cardiac arrest. This was a prospective, multicenter, observational study. Twelve months of consecutive data were collected from emergency medical services (EMS), fire, and inpatient records from 2000 to 2003 for all OHCAs secondary to trauma in patients aged ≤18 years in 36 urban and suburban communities supporting advanced life support (ALS) programs. Eligible patients were apneic and pulseless and received chest compressions in the field. The primary outcome was survival to discharge. Secondary measures included return of spontaneous circulation (ROSC), survival to hospital admission, and 24-hour survival. RESULTS The study included 123 patients. The median patient age was 7.3 years (interquartile range [IQR] 6.0-17.0). The patient population was 78.1% male and 59.0% African American, 20.5% Hispanic, and 15.7% white. Most cardiac arrests occurred in residential (47.1%) or street/highway (37.2%) locations. Initial recorded rhythms were asystole (59.3%), pulseless electrical activity (29.1%), and ventricular fibrillation/tachycardia (3.5%). The majority of cardiac arrests were unwitnessed (49.5%), and less than 20% of patients received chest compressions by bystanders. The median (IQR) call-to-arrival interval was 4.9 (3.1-6.5) minutes and the on-scene interval was 12.3 (8.4-18.3) minutes. Blunt and penetrating traumas were the most common mechanisms (34.2% and 25.2%, respectively) and were associated with poor survival to discharge (2.4% and 6.5%, respectively). For all OHCA patients, 19.5% experienced ROSC in the field, 9.8% survived the first 24 hours, and 5.7% survived to discharge. Survivors had triple the rate of bystander cardiopulmonary resuscitation (CPR) than nonsurvivors (42.9% vs. 15.2%). Unlike patients sustaining blunt trauma or strangulation/hanging, most post-cardiac arrest patients who survived the first 24 hours after penetrating trauma or drowning were discharged alive. Drowning (17.1% of cardiac arrests) had the highest survival-to-discharge rate (19.1%). CONCLUSIONS The overall survival rate for OHCA in children after trauma was low, but some trauma mechanisms are associated with better survival rates than others. Most OHCA in children is preventable, and education and prevention strategies should focus on those overrepresented populations and high-risk mechanisms to improve mortality.

Abstract
INTRODUCTION Many consider attempted resuscitation for traumatic out-of-hospital cardiac arrest (OHCA) futile. This study aims to describe the characteristics and profile of paediatric traumatic OHCA. METHODS The Victorian Ambulance Cardiac Arrest Registry (VACAR) was used to identify all trauma related cases of OHCA in patients aged less than 16 years of age. Cases were linked with their coronial findings. RESULTS Between 2000 and 2009, EMS attended 33,722 OHCAs including 2187 adult traumatic OHCAs. There were 538 (1.6%) OHCAs in children less than 16 years of age of which n=64 were due to trauma. The median age (IQR) of paediatric traumatic OHCA was 7 (4.5-13) years and 44 were male (69%). Bystander CPR was performed in 22 cases (34.4%). The first recorded rhythm by EMS was asystole seen in 42 (66%), PEA in 14 (22%) cases and VF in 2 cases (3%). Cardiac output was present in 7 (11%) cases who subsequently had an EMS witnessed OHCA. EMS attempted resuscitation in 35 (55%) patients of whom 7 (20%) achieved ROSC and were transported, and 1 (3%) survived to hospital discharge with severe neurological sequelae; 14(40%) were transported with CPR of whom none survived. Coronial cause of death was multiple injuries in 35%, head injury in 33%, head and neck injury in 10%, chest injuries in 10% and other causes (12%). CONCLUSIONS Traumatic aetiology of OHCA when compared to the incidence of adult traumatic OHCAs is uncommon. Resuscitation efforts are seldom effective and associated with poor neurological outcome.

Abstract
OBJECTIVE Few data are available on traumatic cardiopulmonary arrest in children. Efforts at resuscitation typically result in heavy utilization of finite resources with little understanding of which characteristics, if any, may be associated with success. The objectives of this study were to describe the outcome of children in traumatic cardiac arrest and to identify patients for whom aggressive resuscitation may or may not be warranted. METHODS Data were analyzed from a previous study of prehospital pediatric airway management in Los Angeles and Orange Counties, Calif, over a 33-month period. Patients included in this secondary analysis were younger than 13 years and found pulseless and apneic after having had an injury. Data sources included prospective, phone interviews with paramedics after transfer of care to the receiving facility, and chart review to determine outcome. Two main outcomes were assessed: survival and neurological function as measured by the Pediatric Cerebral Performance Category. RESULTS The emergency medical services responded to 118 traumatic arrests during the study period. Of these victims, only 6 (5%) survived. Median Injury Severity Score was 25 with an interquartile range of 16 to 75. The survivors all were neurologically impaired with a median Pediatric Cerebral Performance Category of 5 (interquartile range, 4-5). CONCLUSIONS Children who had trauma resulting in cardiac arrest have universally poor outcomes, and survivors have severe neurological compromise. We are unable to identify a subset of patients for whom aggressive resuscitation is indicated. This is the largest prospective study of pediatric traumatic arrest to date.

Abstract
BACKGROUND The goal of this investigation is to determine the success rate of aggressive cardiorespiratory resuscitation in children who experience blunt cranial trauma of sufficient magnitude to quickly cause cardiac arrest. METHODS The records of all the children who, within a 6-year period, suffered cardiac arrest at the scene of injury, during transport or in the emergency department of a level one pediatric trauma center, as a consequence of blunt cranial trauma, form the basis of this study. RESULTS One of the 40 children who met the inclusion criteria survived. Their ages ranged from 1 month to 16 years, and all had a Glasgow Coma Score of 3 at the scene of injury. Forty-two percent were passengers in motor vehicles, and 32% were victims of nonaccidental trauma. Eleven of the 17 children in the motor vehicle crash were not properly restrained. Eleven of the unrestrained children plus two who were properly restrained were ejected at the time of impact. The average cardiopulmonary resuscitation time was 36 (2-107) minutes. A sinus rhythm was established in 50% but was not sustained in most. The sole survivor was an 8-year-old boy who was ejected and had asystole at the scene. At discharge, he was walking well but had cranial nerve deficits and learning disability. CONCLUSION Survival in 40 consecutive children with documented cardiac arrest caused by blunt cranial trauma was 2.5%. This series, when combined with other published reports, is supportive of the position that aggressive resuscitation is rarely successful after 10 minutes and futile after 20 minutes.

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
BACKGROUND Guidelines for termination of resuscitation in prehospital traumatic cardiopulmonary arrest (TCPA) have recently been published for adults. Clinical criteria for termination of care include absent pulse, unorganized electrocardiogram (ECG), fixed pupils (all at the scene), and cardiopulmonary resuscitation (CPR) greater than 15 minutes. The goal of this study was to evaluate these guidelines in a pediatric trauma population. METHODS Pediatric trauma patients with documented arrest were included in the study. Data assessed were duration of CPR, ECG rhythm, pulse assessment, pupil response, transport times, and standard injury criteria (eg, mechanism of injury). Survivors were compared to nonsurvivors using descriptive statistics, chi(2), and Pearson correlation. RESULTS Between 2000 and 2009, 30 patients were identified as having had a TCPA. Of the 30 with a prehospital TCPA, there were 9 females and 21 males (0.2-18 years old). The average (SD) injury severity score was 35.4 (20.6). Twenty-four patients (80%) did not survive. Severe traumatic brain injury was associated with nonsurvivors in 78%. One-way analysis of variances demonstrated that CPR greater than 15 minutes (P = .011) and fixed pupils (P = .022) were significant variables to distinguish between survivors and nonsurvivors, whereas ECG rhythm (P = .34) and absent pulse (P = .056) did not, 42 +/- 28 minutes for nonsurvivors and 7 +/- 3 minutes for survivors. CONCLUSION Criteria for termination of resuscitation correctly predicted 100% of those who died when all the criteria were met. More importantly, no survivors would have had resuscitation stopped. Duration of CPR seems to be a strong predictor of mortality in this study.

Abstract
More than 25% of children survive to hospital discharge after in-hospital cardiac arrests, and 5% to 10% survive after out-of-hospital cardiac arrests. This review of pediatric cardiopulmonary resuscitation addresses the epidemiology of pediatric cardiac arrests, mechanisms of coronary blood flow during cardiopulmonary resuscitation, the 4 phases of cardiac arrest resuscitation, appropriate interventions during each phase, special resuscitation circumstances, extracorporeal membrane oxygenation cardiopulmonary resuscitation, and quality of cardiopulmonary resuscitation. The key elements of pathophysiology that impact and match the timing, intensity, duration, and variability of the hypoxic-ischemic insult to evidence-based interventions are reviewed. Exciting discoveries in basic and applied-science laboratories are now relevant for specific subpopulations of pediatric cardiac arrest victims and circumstances (eg, ventricular fibrillation, neonates, congenital heart disease, extracorporeal cardiopulmonary resuscitation). Improving the quality of interventions is increasingly recognized as a key factor for improving outcomes. Evolving training strategies include simulation training, just-in-time and just-in-place training, and crisis-team training. The difficult issue of when to discontinue resuscitative efforts is addressed. Outcomes from pediatric cardiac arrests are improving. Advances in resuscitation science and state-of-the-art implementation techniques provide the opportunity for further improvement in outcomes among children after cardiac arrest.

Abstract
OBJECTIVE To examine survival rates for paediatric trauma patients requiring cardiopulmonary resuscitation (CPR) in the pre-hospital setting, and to identify characteristics that may be associated with survival. DESIGN Ten-year retrospective trauma database review. SETTING An urban physician-led pre-hospital trauma service serving a population of approximately 7.5 million, in the United Kingdom. PATIENTS Eighty paediatric trauma patients (15 years or less) who received pre-hospital resuscitation following cardiorespiratory arrest between July 1994 and June 2004. INTERVENTION Pre-hospital cardiopulmonary resuscitation. MAIN OUTCOME MEASURE Survival to hospital discharge. RESULTS Eighty children met inclusion criteria for the study. Nineteen (23.8%) were discharged alive from the emergency department and seven children (8.75%) survived to hospital discharge. Of the seven survivors, one had spinal cord injury. Two suffered asphyxial injury associated with blunt trauma and three sustained hypoxic insults following drowning or burns/smoke inhalation. In one patient with known congenital cardiac disease the cause of cardiac arrest was likely to have been medical. CONCLUSION This study confirms the poor outcome for children requiring pre-hospital CPR following trauma. However, the results are better in this physician-attended group than in other studies where physicians were not present. They also suggest that cardiac arrest associated with trauma in children has a better outcome than in adults. In common with adults treated in this system, those patients with hypovolaemic cardiac arrest did not survive (Ann Emerg Med 2006;48:240-4). A large proportion of the survivors suffered hypoxic or asphyxial injuries. Targeted aggressive out-of-hospital resuscitation in certain patient groups can produce good outcomes.

Abstract
The use of cardiopulmonary resuscitation (CPR) is accepted universally for patients with cardiovascular compromise. However, outcomes from CPR in subsets of trauma patients may not be as good as initially thought. This article reviews the literature on outcomes from traumatic arrest in both adults and children. Outcomes for adults and children are similar, although the types of injuries may differ. Patients with asystolic arrest at the scene have very poor survival, and those who do survive sustain severe neurological injury. Recognizing that most providers would feel uncomfortable at not attempting resuscitation, the length and degree of aggressiveness of CPR is addressed. Finally, we discuss possible reasons to resuscitate. Organ donation and the ethics of nontherapeutic ventilation and other strategies to increase the donor pool are discussed. We hope to stimulate discussion around a very difficult issue.

Abstract
BACKGROUND Paediatric patients with out-of-hospital cardiac arrest (OHCA) due to trauma pose difficult challenges in resuscitation. Trauma is a major cause of OHCA in children. The aim of this study was to determine which factors were related to predicting a sustained return of spontaneous circulation (ROSC) in paediatric OHCA patients with trauma. METHOD This retrospective study comprised 115 paediatric patients (56 traumatic and 59 non-traumatic OHCA patients) aged younger than 18 years who had been admitted to the emergency department (ED) from January 2000 to December 2004. We analysed the demographic data and the factors that may have influenced sustained ROSC in the group of OHCA paediatric patients with trauma. The non-trauma group was established as a control group. Survival analysis was used to compare differences in survival rate between trauma and non-trauma OHCA patients. Receiver operating characteristic (ROC) analysis was used to determine the significant in-hospital CPR duration related to sustained ROSC. RESULTS Initial cardiac rhythm on arrival (P=0.005) and the duration of in-hospital CPR (P<0.001) were significant factors. Patients with PEA or VF had higher rate of sustained ROSC than those with asystole (PEA: P=0.003, VF: P=0.03). In the survival analysis, OHCA children with trauma had a lower chance of survival than non-trauma children as the interval from the scene to the ER increased (P=0.008). Based on the ROC analysis, the cut-off values of in-hospital CPR duration were 25min in OHCA paediatric patients with trauma. CONCLUSION Several significant factors relating to sustained ROSC were determined in the OHCA paediatric patients with trauma; most importantly, we found that in-hospital CPR may have to be performed for at least 25min to enable a spontaneous circulation to return.

Abstract
OBJECTIVE To analyze the characteristics and outcome of cardiorespiratory arrest secondary to trauma in children. PATIENTS AND METHODS We performed a secondary analysis of data from a prospective, multicenter study of cardiorespiratory arrest in children. Data were recorded according to the Utstein style. Twenty-eight children (age range: 7 days to 16 years) with cardiorespiratory arrest secondary to trauma were evaluated. The outcome variables were return of spontaneous circulation, sustained (more than 20 minutes) return of spontaneous circulation (initial survival), and survival at hospital discharge (final survival) in relation to the characteristics of the cardiorespiratory arrest and cardiopulmonary resuscitation. Neurological and general performance outcome was assessed by means of the Pediatric Cerebral Performance Category scale and the Pediatric Overall Performance Category scale. RESULTS Return of spontaneous circulation was obtained in 18 patients (64.2 %), initial survival was achieved in 14 (50 %) and final survival was achieved in three (10.7 %) (two without neurological sequelae and one with vegetative status). Final survival was significantly higher in patients with respiratory arrest (33.3 %) than in those with cardiac arrest (4.5 %), p = 0.04. Final survival was also higher in patients with a duration of cardiopulmonary resuscitation shorter than 20 minutes (27.2 %) than in the remaining patients (0 %), p =0.05. The two survivors without neurologic sequelae had respiratory arrest. CONCLUSIONS Survival until hospital discharge in children with cardiorespiratory arrest secondary to trauma is lower than that in children with cardiorespiratory arrest. Patients with respiratory arrest when resuscitation is started and those with a duration of cardiopulmonary resuscitation of less than 20 minutes showed better survival than the remaining patients.

Abstract
This publication contains the pediatric and neonatal sections of the 2005 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations (COSTR). The consensus process that produced this document was sponsored by the International Liaison Committee on Resuscitation (ILCOR). ILCOR was formed in 1993 and consists of representatives of resuscitation councils from all over the world. Its mission is to identify and review international science and knowledge relevant to cardiopulmonary resuscitation (CPR) and emergency cardiovascular care (ECC) and to generate consensus on treatment recommendations. ECC includes all responses necessary to treat life-threatening cardiovascular and respiratory events. The COSTR document presents international consensus statements on the science of resuscitation. ILCOR member organizations are each publishing resuscitation guidelines that are consistent with the science in this consensus document, but they also take into consideration geographic, economic, and system differences in practice and the regional availability of medical devices and drugs. The American Heart Association (AHA) pediatric and the American Academy of Pediatrics/AHA neonatal sections of the resuscitation guidelines are reprinted in this issue of Pediatrics (see pages e978-e988). The 2005 evidence evaluation process began shortly after publication of the 2000 International Guidelines for CPR and ECC. The process included topic identification, expert topic review, discussion and debate at 6 international meetings, further review, and debate within ILCOR member organizations and ultimate approval by the member organizations, an Editorial Board, and peer reviewers. The complete COSTR document was published simultaneously in Circulation (International Liaison Committee on Resuscitation. 2005 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations. Circulation. 2005;112(suppl):73-90) and Resuscitation (International Liaison Committee on Resuscitation. 2005 International Consensus Conference on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations. Resuscitation. 2005;67:271-291). Readers are encouraged to review the 2005 COSTR document in its entirety. It can be accessed through the CPR and ECC link at the AHA Web site: www.americanheart.org. The complete publication represents the largest evaluation of resuscitation literature ever published and contains electronic links to more detailed information about the international collaborative process. To organize the evidence evaluation, ILCOR representatives established 6 task forces: basic life support, advanced life support, acute coronary syndromes, pediatric life support, neonatal life support, and an interdisciplinary task force to consider overlapping topics such as educational issues. The AHA established additional task forces on stroke and, in collaboration with the American Red Cross, a task force on first aid. Each task force identified topics requiring evaluation and appointed international experts to review them. A detailed worksheet template was created to help the experts document their literature review, evaluate studies, determine levels of evidence, develop treatment recommendations, and disclose conflicts of interest. Two evidence evaluation experts reviewed all worksheets and assisted the worksheet reviewers to ensure that the worksheets met a consistently high standard. A total of 281 experts completed 403 worksheets on 275 topics, reviewing more than 22000 published studies. In December 2004 the evidence review and summary portions of the evidence evaluation worksheets, with worksheet author conflict of interest statements, were posted on the Internet at www.C2005.org, where readers can continue to access them. Journal advertisements and e-mails invited public comment. Two hundred forty-nine worksheet authors (141 from the United States and 108 from 17 other countries) and additional invited experts and reviewers attended the 2005 International Consensus Conference for presentation, discussion, and debate of the evidence. All 380 participants at the conference received electronic copies of the worksheets. Internet access was available to all conference participants during the conference to facilitate real-time verification of the literature. Expert reviewers presented topics in plenary, concurrent, and poster conference sessions with strict adherence to a novel and rigorous conflict of interest process. Presenters and participants then debated the evidence, conclusions, and draft summary statements. Wording of science statements and treatment recommendations was refined after further review by ILCOR member organizations and the international editorial board. This format ensured that the final document represented a truly international consensus process. The COSTR manuscript was ultimately approved by all ILCOR member organizations and by an international editorial board. The AHA Science Advisory and Coordinating Committee and the editor of Circulation obtained peer reviews of this document before it was accepted for publication. The most important changes in recommendations for pediatric resuscitation since the last ILCOR review in 2000 include: Increased emphasis on performing high quality CPR: "Push hard, push fast, minimize interruptions of chest compression; allow full chest recoil, and don't provide excessive ventilation" Recommended chest compression-ventilation ratio: For lone rescuers with victims of all ages: 30:2 For health care providers performing 2-rescuer CPR for infants and children: 15:2 (except 3:1 for neonates) Either a 2- or 1-hand technique is acceptable for chest compressions in children Use of 1 shock followed by immediate CPR is recommended for each defibrillation attempt, instead of 3 stacked shocks Biphasic shocks with an automated external defibrillator (AED) are acceptable for children 1 year of age. Attenuated shocks using child cables or activation of a key or switch are recommended in children <8 years old. Routine use of high-dose intravenous (IV) epinephrine is no longer recommended. Intravascular (IV and intraosseous) route of drug administration is preferred to the endotracheal route. Cuffed endotracheal tubes can be used in infants and children provided correct tube size and cuff inflation pressure are used. Exhaled CO2 detection is recommended for confirmation of endotracheal tube placement. Consider induced hypothermia for 12 to 24 hours in patients who remain comatose following resuscitation. Some of the most important changes in recommendations for neonatal resuscitation since the last ILCOR review in 2000 include less emphasis on using 100% oxygen when initiating resuscitation, de-emphasis of the need for routine intrapartum oropharyngeal and nasopharyngeal suctioning for infants born to mothers with meconium staining of amniotic fluid, proven value of occlusive wrapping of very low birth weight infants <28 weeks' gestation to reduce heat loss, preference for the IV versus the endotracheal route for epinephrine, and an increased emphasis on parental autonomy at the threshold of viability. The scientific evidence supporting these recommendations is summarized in the neonatal document (see pages e978-e988).

Abstract
BACKGROUND According to the literature, the overall outcome in a patient population with chest or abdominal injury with initial cardiac arrest has to be rated as poor. In cases of penetrating injuries, open-chest cardiopulmonary resuscitation (CPR) has been recommended as a treatment option to improve the survival rate. The aim of this study was to prove equal outcome for patients with blunt chest or abdominal trauma. METHODS During a 5-year period, a consecutive patient series admitted to an urban Level I trauma center was examined. Only patients with blunt trauma and witnessed cardiac arrest, who had a documented, uninterrupted closed-chest CPR (CCCPR) of less than 20 minutes were included in this study (n=38). Exclusion criteria were age over 70 years, penetrating injuries, CCCPR of more than 20 minutes, as well as nonprofessional bystander resuscitation. RESULTS Four of 38 patients survived. In comparison with the group of nonsurvivors, both groups showed a similar age and gender ratio (mean age, 28, 32, respectively). The mean Injury Severity Scale was 54 (range, 42-66) in the survivor group and 66 (range, 29-75) in the nonsurvivor group, respectively. The time of CCCPR was on average 13 minutes (range, 11-15 minutes) for the survivors and 16 minutes (range, 1-20 minutes) for the nonsurvivors. CONCLUSION Patients with blunt trunk trauma and cardiac arrest after hemorrhagic shock may benefit from open-chest CPR with the same probability as shown for patients with penetrating injuries. This is especially true if the procedure is started as soon as possible, but at the latest within 20 minutes after initial CCCPR.

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
The evolving understanding of pathophysiologic events during and after pediatric cardiac arrest has not yet resulted in significantly improved outcome. Exciting breakthroughs in basic and applied science laboratories are, however, on the immediate horizon for study in specific subpopulations of cardiac arrest victims. Strategically focusing therapies to specific phases of cardiac arrest and resuscitation and evolving pathophysiologic events offers great promise that critical care interventions will lead the way to more successful cardiopulmonary and cerebral resuscitation in children.

Abstract
OBJECTIVE Epinephrine is widely used for treatment of life-threatening hypotension, although new vasopressor drugs may merit evaluation. The purpose of this study was to determine the effects of vasopressin vs. epinephrine vs. saline placebo on hemodynamic variables, regional blood flow, and short-term survival in an animal model of uncontrolled hemorrhagic shock and delayed fluid resuscitation. DESIGN Prospective, randomized, laboratory investigation that used a porcine model for measurement of hemodynamic variables and regional abdominal organ blood flow. SETTING University hospital laboratory. SUBJECTS A total of 21 pigs weighing 32 +/- 3 kg. INTERVENTIONS The anesthetized pigs were subjected to a penetrating liver injury, which resulted in a mean +/- sem loss of 40% +/- 5% of estimated whole blood volume within 30 mins and mean arterial pressures of <20 mm Hg. When heart rate declined progressively, pigs randomly received a bolus dose and continuous infusion of either vasopressin (0.4 units/kg and 0.04 units.kg-1.min-1, n = 7), or epinephrine (45 microg/kg and 5 microg.kg(-1).min(-1), n = 7), or an equal volume of saline placebo (n = 7), respectively. At 30 mins after drug administration, all surviving animals were fluid resuscitated while bleeding was surgically controlled. MEASUREMENTS AND MAIN RESULTS Mean +/- sem arterial blood pressure at 2.5 and 10 mins was significantly (p <.001) higher after vasopressin vs. epinephrine vs. saline placebo (82 +/- 14 vs. 23 +/- 4 vs. 11 +/- 3 mm Hg, and 42 +/- 4 vs. 10 +/- 5 vs. 6 +/- 3 mm Hg, respectively). Although portal vein blood flow was temporarily impaired by vasopressin, it was subsequently restored and significantly (p <.01) higher when compared with epinephrine or saline placebo (9 +/- 5 vs. 121 +/- 3 vs. 54 +/- 22 mL/min and 150 +/- 20 vs. 31 +/- 17 vs. 0 +/- 0 mL/min, respectively). Hepatic and renal artery blood flow was significantly higher throughout the study in the vasopressin group; however, no further bleeding was observed. Despite a second bolus dose, all epinephrine- and saline placebo-treated animals died within 15 mins after drug administration. By contrast, seven of seven vasopressin-treated animals survived until fluid replacement, and 60 mins thereafter, without further vasopressor therapy (p <.01). Moreover, blood flow to liver, gut, and kidney returned to normal values in the postshock phase. CONCLUSIONS Vasopressin, but not epinephrine or saline placebo, improved short-term survival in a porcine model of uncontrolled hemorrhagic shock after liver injury when surgical intervention and fluid replacement was delayed.

Abstract
PURPOSE Injury is the leading cause of cardiac arrest in children older than 1 year. Previous findings suggest that children who require cardiopulmonary resuscitation (CPR) administered by paramedics for any reason rarely survive to hospital discharge. The authors evaluated the outcome of children sustaining cardiac arrest after blunt trauma in a Regional Pediatric Trauma Center. METHODS Children (age < 16) who underwent CPR in the field or in the emergency department (ED) after blunt trauma were identified from the trauma registry of a regional pediatric trauma center over a 3-year period (1997 to 2000). Patient demographics, rate of survival to discharge, factors influencing survival, and organ donation data were obtained from the trauma registry and medical record. Probability of survival (Ps) was calculated by TRISS analysis. RESULTS Twenty-five children were identified with a history of cardiac arrest after blunt injury (mean age; 3.3 years; range, 0.1 to 10; mean ISS, 30.7; range, 13-75; mean RTS, 1.58). Mean calculated Ps was 22.7%. However, only 2 (8%) survived. Death in the majority (91%) of the 23 patients who died occurred secondary to brain or spinal cord injury, and only 2 (9%) occurred as the result of exsanguinating hemorrhage. CPR was first performed in the field in 10 patients (40%), en route in 6 (24%), and in the ED in 9 (36%). Of the children who survived, both had vitals in the field, and CPR was administered initially in the ED. Mean length of ED resuscitation before death was 80 minutes. Of the children who died, organ donation occurred in only 3 (13%). The 2 survivors had no head injury and were discharged within 3 weeks of injury. CONCLUSIONS Cardiopulmonary resuscitation after blunt injury in children rarely results in survival. The majority of deaths occur as a result of isolated intracranial injury and not exsanguinating hemorrhage. Although all children should receive aggressive resuscitation after injury, the need for CPR in the field portends a poor outcome. Furthermore, these data would suggest that prolonged or heroic efforts for children sustaining cardiac arrest in the field are not indicated.

Abstract
Vasopressin (antidiuretic hormone) is emerging as a potentially major advance in the treatment of a variety of shock states. Increasing interest in the clinical use of vasopressin has resulted from the recognition of its importance in the endogenous response to shock and from advances in understanding of its mechanism of action. From animal models of shock, vasopressin has been shown to produce greater blood flow diversion from non-vital to vital organ beds (particularly the brain) than does adrenaline. Although vasopressin has similar direct actions to the catecholamines, it may uniquely also inhibit some of the pathologic vasodilator processes that occur in shock states. There is current interest in the use of vasopressin in the treatment of shock due to ventricular fibrillation, hypovolaemia, sepsis and cardiopulmonary bypass. This article reviews the physiology and pharmacology of vasopressin and all of the relevant animal and human clinical literature on its use in the treatment of shock following a MEDLINE (1966-2000) search.

Abstract
AIMS To evaluate the performance of guidelines for emergency triage and treatment (ETAT) of children presenting to hospitals in the developing world. Part of the study was concerned with the delivery of emergency treatment to the sickest group of patients, characterisation of their illness, and outcome. METHODS AND RESULTS A total of 236 children were admitted during the study period, 27 of whom died. The three main causes of death were malaria or malaria related illness (n = 7), pneumonia (n = 6), and malnutrition (n = 11). Forty seven children were categorised as needing emergency treatment. Thirty one had no treatment, and eight died; 16 received one or more recommended treatments, of whom five died. The main limitations to delivery of immediate care were the lack of staff in the department and lack of rapidly available blood.

Abstract
STUDY OBJECTIVE We sought to examine the outcome of a subgroup of patients with extreme carbon monoxide (CO) poisoning, specifically those discovered in cardiac arrest, resuscitated, and subsequently treated with hyperbaric oxygen (HBO(2)). Opinions of hyperbaric medicine physicians regarding the treatment of such patients were also sought. METHODS Records of patients treated with HBO(2) for acute CO poisoning at Virginia Mason Medical Center in Seattle from September 1987 to August 2000 were reviewed. Those who were resuscitated from cardiac arrest in the field before HBO(2) treatment were selected for detailed analysis. Patient demographic data and information regarding circumstances of the poisoning, resuscitation, HBO(2) treatment, and subsequent course were extracted and collated. In addition, a postal survey of medical directors of North American HBO(2) treatment facilities regarding opinions about the management and outcome of such patients was performed. RESULTS A total of 18 patients were treated with HBO(2) after resuscitation from CO-associated cardiac arrest. They included 10 female and 8 male patients ranging in age from 3 to 72 years. Sources of CO included house fires (10 patients) and automobile exhaust (8 patients). Patient carboxyhemoglobin levels averaged 31.7%+/-11.0% (mean+/-SD), and arterial pH averaged 7.14+/-0.19. Presenting cardiac rhythm was a bradydysrhythmia in 10 of 18 patients. HBO(2) treatment was administered an average of 4.3 hours after poisoning (< or = 3 hours in 10 patients and < or = 6 hours in 15 patients). Despite this, all 18 patients died during their hospitalizations. Medical directors of hyperbaric treatment facilities estimated a 74% likelihood of survival for a hypothetical patient with this presentation. CONCLUSION In this consecutive case series, cardiac arrest complicating CO poisoning was uniformly fatal, despite administration of HBO(2) therapy after initial resuscitation. Survey results suggest that physician education regarding this subset of CO-poisoned patients is needed. The prognosis of this condition should be considered when making triage and treatment decisions for patients poisoned to this severity.

Abstract
UNLABELLED Survival after hypovolemic shock and cardiac arrest is dismal with current therapies. We evaluated the potential benefits of vasopressin versus large-dose epinephrine in hemorrhagic shock and cardiac arrest on vital organ perfusion, and the likelihood of resuscitation. In 18 pigs, 35% of the estimated blood volume was withdrawn over 15 min and ventricular fibrillation was induced 5 min later. After 4 min of cardiac arrest and 4 min of standard cardiopulmonary resuscitation, a bolus dose of either 200 microg/kg epinephrine (n = 7), 0.8 unit/kg vasopressin (n = 7), or saline placebo (n = 4) was administered in a blinded, randomized manner. Defibrillation was attempted 2.5 min after drug administration, and all animals were subsequently observed for 1 h without further intervention. Spontaneous circulation was restored in 7 of 7 vasopressin animals, in 6 of 7 epinephrine pigs, and in 0 of 4 placebo swine. At 5 and 30 min after return of spontaneous circulation, median (minimum and maximum) renal blood flow after epinephrine was 2 (0-31), and 2 (0-48) mL. 100 g(-1). min(-1), respectively; and after vasopressin 96 (12-161), and 44 (16-105) mL. 100 g(-1). min(-1), respectively (P: <.01 between groups). Epinephrine animals developed a profound metabolic acidosis by 15 min after return of spontaneous circulation (mean arterial pH, 7.11 +/- 0.01), and by 60 min all epinephrine-treated animals had died. The vasopressin pigs had (P: = 0.015) less acidosis (pH = 7.26+/-0. 04) at corresponding time points, and all survived > or =55 min (P: < 0. 01). In conclusion, treatment of hypovolemic cardiac arrest with vasopressin, but not with large-dose epinephrine or saline placebo, resulted in sustained vital organ perfusion, less metabolic acidosis, and prolonged survival. Based on these findings, clinical evaluation of vasopressin during hypovolemic cardiac arrest may be warranted. IMPLICATIONS The chances of surviving cardiac arrest in hemorrhagic shock are considered dismal without adequate fluid replacement. However, treatment of hypovolemic cardiac arrest with vasopressin, but not with large-dose epinephrine or saline placebo, resulted in sustained vital organ perfusion and prolonged survival in an animal model of suspended infusion therapy.

Abstract
The epidemiology and outcome of pediatric cardiopulmonary arrest and the priorities, techniques, and sequence of pediatric resuscitation assessments and intervention differ from those of adults. Current guidelines have been updated after extensive multinational evidence-based review and discussion over several years. Areas of controversy in current guidelines and recommendations made by consensus are detailed. A large degree of uniformity exists in the current guidelines advocated by the AHA, Council on Latin American Resuscitation, Heart and Stroke Foundation of Canada, European Resuscitation Council, Australian Resuscitation Council, and Resuscitation Council of Southern Africa. Differences are currently based on local and regional preferences, training networks, and customs rather than scientific controversy. Unresolved issues with potential for future universal application are highlighted.

Abstract
STUDY OBJECTIVE To report paediatric in-hospital cardiac arrest data according to Utstein style and to determine the effectiveness of cardiopulmonary resuscitation (CPR) in hospitalized children. DESIGN Retrospective 5-year case series. SETTING Urban, tertiary-care children's hospital. PARTICIPANTS All patients who sustained cardiopulmonary arrest. RESULTS Altogether 227 patients experienced a cardiopulmonary arrest during the study period, 109 (48.0%) were declared dead without attempted resuscitation, and CPR was initiated in 118 (52.0%). The incidence of cardiac arrest was 0. 7% of all hospital admissions and 5.5% of PICU admissions; the incidence of CPR attempts was 0.4 and 2.5%, respectively. Most of the CPR attempts (64.4%) took place in the PICU and the most frequent aetiology was cardiovascular (71.2%). The 1-year survival rate was 17.8%. Short duration of external CPR was the best prognostic factor associated with survival. With few exceptions, the Paediatric Utstein Style was found to be applicable for reporting retrospective data from in-hospital cardiac arrests in children. CONCLUSIONS In-hospital cardiopulmonary resuscitation was shown to be an uncommon event in children; the survival rate was similar to earlier studies.
