ObjectivesOut-of-hospital cardiac arrest (OHCA) is rare in infants, with the cause of arrest often unknown upon presentation. Nonaccidental trauma is a potential etiology of OHCA among infants, but its occult presentation makes this etiology challenging to diagnose. In the absence of apparent injuries, identifying the need for trauma team activation is difficult during the initial resuscitation of infants with OHCA.MethodsWe performed a retrospective chart review of infants younger than 1 year old who presented to Children's National Health System from 2012 to 2016 with cardiopulmonary resuscitation in progress. Medical records and the trauma registry were reviewed for relevant resuscitation information. Autopsy records provided the cause and manner of death, contributing factors to death, and evidence of injury.ResultsAmong 592 infants undergoing resuscitation during the study period, 34 infants (5.7%) presented in cardiac arrest. The average age on presentation was 101.2 days (standard deviation 78.7). Most of the patients (n = 32, 94.1%) died in the emergency department, with none surviving to discharge. Among the 32 infants for whom autopsy records were available, the cause of death was nonaccidental trauma in one patient (3.1%).ConclusionsInfant OHCA had poor outcomes, with trauma as a rare etiology. In the absence of external signs of injury or known injury mechanism, immediate trauma team presence was not beneficial for these infants during the initial resuscitation phase.
