Severe brain edema appears early after cardiopulmonary resuscitation (CPR) in a subset of patients and portends a poor prognosis. We tested whether clinical features of patients or resuscitation during out-of-hospital cardiac arrest (OHCA) are associated with early, severe cerebral edema. ⋯ CPR duration along with easily measurable clinical and resuscitation characteristics predict early severe cerebral edema after OHCA. Future interventional trials should consider targeting or preventing cerebral edema after prolonged hypoxic-ischemic brain injury especially in patients with high risk clinical features.

The American Heart Association (AHA) recommends first defibrillation energy dose of 2 Joules/kilogram (J/kg) for pediatric cardiac arrest with ventricular fibrillation (VF) or pulseless ventricular tachycardia (pVT). However, optimal first energy dose remains unclear.

Review Meta Analysis
Pre-Arrest and Intra-Arrest Prognostic Factors Associated with Survival Following Traumatic Out-of-Hospital Cardiac Arrest-A Systematic Review and Meta-Analysis.
To summarize the prognostic associations of pre- and intra-arrest factors with return of spontaneous circulation (ROSC) and survival (in-hospital or 30 days) after traumatic out-of-hospital cardiac arrest. ⋯ This review provides very low to moderate certainty evidence that pre- and intra-arrest prognostic factors following penetrating or blunt traumatic OHCA predict ROSC and survival. This evidence is primarily based on unadjusted data. Further well-designed studies with larger cohorts are warranted to test the adjusted prognostic ability of pre- and intra-arrest factors and guide therapeutic decision-making.

To quantify the accuracy of health care providers' predictions of survival and function at hospital discharge in a prospective cohort of patients resuscitated from cardiac arrest. To test whether self-reported confidence in their predictions was associated with increased accuracy and whether this relationship varied across providers. ⋯ Providers varied in accuracy predicting post-arrest outcomes and most errors were optimistic. Self-reported confidence explained little variation in accuracy.

The absence of nationwide surveillance data on out-of-hospital cardiac arrest (OHCA) in the United States (US) limits understanding of the epidemiology of paediatric OHCA. We investigated the national characteristics of paediatric OHCA using the National Emergency Medical Services Information System (NEMSIS). ⋯ Using data from the NEMSIS, we estimate that there are over 23,000 annual paediatric OHCA in the US. These data provide key insights of paediatric OHCA in the US.
