P2919Bystander chest compression-only cardiopulmonary resuscitation in children with out-of-hospital cardiac arrest

Background/Introduction: Rates of neurologically intact survival have increased in children aged 1–17 years receiving bystander chest compression-only cardiopulmonary resuscitation (CC-CPR) after out-of-hospital cardiac arrest (OHCA). Differences between conventional CPR and CC-CPR in their rates of favourable neurological outcomes have gradually decreased, especially after the 2010 update of international CPR guidelines. Purpose: To compare neurologically intact survival rates (Cerebral Performance Category 1 or 2, [CPC 1–2]) in children with OHCA undergoing CC-CPR and conventional CPR. Methods: The study included 2538 Japanese children aged 1–17 years in a prospectively recorded nationwide Utstein-style database who experienced OHCA from 2011 through 2015 and were treated by emergency medical service providers after receiving bystander CPR (CC-CPR or conventional CPR). Patients were divided into two age groups, those aged 1–7 (n=1134) and 8–17 (n=1404) years. Crude rates and adjusted odds ratios (ORs) for 30-day outcomes were analysed before and after propensity-score matching of patients in the two cohorts who underwent conventional CPR and CC-CPR.
