Chang I, et al. - Among pediatric patients with out-of-hospital cardiac arrest (OHCA), the impact of bystander cardiopulmonary resuscitation (BCPR) with dispatcher assistance (DA) on neurological outcomes was investigated based on the response time interval (RTI) of the pre-hospital emergency medical service (EMS). In this retrospective registry study, pediatric patients (< 19 years old) with OHCA who were assessed by EMS providers between 2012 and 2016 were analyzed. Researchers observed good neurological recovery in significant correlation with BCPR with DA and a faster EMS RTI among these patients. The association of BCPR with DA with good neurological recovery in the pediatric patients remained when delayed EMS RTI was seen.
