Epidemiology of out-of hospital pediatric cardiac arrest due to trauma

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.

Cardiac arrest and post resuscitation of the brain

Primary out-of-hospital cardiac arrest in childhood is rare but survival is a little better for children than for adults, although the prognosis for infants is very poor. Hypoxic-ischaemic encephalopathy after in-hospital cardiac arrest in children undergoing complicated treatment for previously untreatable conditions is now a common problem and is probably increasing. An additional ischaemic insult worsens the prognosis for other encephalopathies, such as that occurring after accidental or non-accidental head injury. For near-drowning, the prognosis is often good, provided that cardiopulmonary resuscitation (CPR) is commenced immediately, and the child gasps within 40 minutes of rescue and regains consciousness soon afterwards. The prognosis is much worse for the nearly drowned child admitted to casualty or the emergency room deeply unconscious with fixed dilated pupils, requiring continuing CPR and with an arterial pH <7, especially if there is little recovery by the time of admission to the intensive care unit. The use of adrenaline, sodium bicarbonate and calcium appears to worsen prognosis. Neurophysiology, specifically serial electroencephalography and evoked potentials, is the most useful tool prognostically, although neuroimaging and biomarkers may play a role. In a series of 89 patients studied after cardiac arrest in three London centres between 1982 and 1985, 39% recovered consciousness within one month. Twenty seven percent died a cardiac death whilst in coma, and the outcome in the remainder was either brain death or vegetative state. EEG and initial pH were the best predictors of outcome in this study. Seizures affected one third and were associated with deterioration and worse outcome. The advent of extracorporeal membrane oxygenation (ECMO) and the positive results of hypothermia trials in neonates and adults have rekindled interest in timely management of this important group of patients.

Universally poor outcomes of pediatric traumatic arrest: a prospective case series and review of the literature

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.

Prognosis for children in cardiac arrest shortly after blunt cranial trauma

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.

Organ Procurement After Cardiocirculatory Death: A Critical Analysis

To shorten the transplantation waiting time in the United States, federal regulations have been introduced requiring hospitals to develop policies for organ donation after cardiac (or circulatory) death (DCD). The practice of DCD is invoked based on the validity of the University of Pittsburgh Medical Center (UPMC) protocol and relies on the accuracy of the University of Wisconsin (UW) evaluation tool to appropriately identify organ donors. There is little evidence to support the position that the criteria for organ procurement adopted from the UPMC protocol complies with the dead donor rule. A high false-positive rate of the UW evaluation tool can expose many dying patients to unnecessary perimortem interventions because of donation failure. The medications and/or interventions for the sole purpose of maintaining organ viability can have unintended negative consequences on the timing and quality of end-of-life care offered to organ donors. It is essential to address and manage the evolving conflict between optimal end-of-life care and the necessary sacrifices for the procurement of transplantable organs from the terminally ill. The recipients of marginal organs recovered from DCD can also suffer higher mortality and morbidity than recipients of other types of donated organs. Finally, transparent disclosure to the public of the risks involved to both organ donors and recipients may contribute to open societal debate on the ethical acceptability of DCD.

Blunt intraabdominal arterial injury in pediatric trauma patients: injury distribution and markers of outcome

BACKGROUND

The epidemiology of pediatric blunt intraabdominal arterial injury is ill defined. We analyzed a multiinstitutional trauma database to better define injury patterns and predictors of outcome.

METHODS

The American College of Surgeons National Trauma Database was evaluated for all patients younger than 16 years with blunt intraabdominal arterial injury from 2000 to 2004. Injury distribution, operative treatment, and variables associated with mortality were considered.

RESULTS

One hundred twelve intraabdominal arterial injuries were identified in 103 pediatric blunt trauma patients. Single arterial injury (92.2%) occurred most frequently: renal (36.9%), mesenteric (24.3%), and iliac (23.3%). Associated injuries were present in 96.1% of patients (abdominal visceral, 75.7%; major extraabdominal skeletal/visceral, 77.7%). Arterial control was obtained operatively (n = 46, 44.7%) or by endovascular means (n = 6, 5.8%) in 52 patients. Overall mortality was 15.5%. Increased mortality was associated with multiple arterial injuries (P = .049), intraabdominal venous injury (P = .011), head injury (P = .05), Glasgow Coma Score less than 8 (P < .001), cardiac arrest (P < .001), profound base deficit (P = .007), and poor performance on multiple injured outcomes scoring systems (Revised Trauma Score [P < .001], Injury Severity Score [P = .001], and TRISS [P = .002]).

CONCLUSION

Blunt intraabdominal arterial injury in children usually affects a single vessel. Associated injuries appear to be nearly universal. The high mortality rate is influenced by serious associated injuries and is reflected by overall injury severity scores.
