Abstract 370: Delivery of CPR in Patients With Single and Biventricular Cardiac Disease

Abstract

Introduction: Diminished survival after cardiopulmonary resuscitation (CPR) has been shown in patients with congenital heart disease (CHD) and single ventricle (SV) anatomy compared to biventricular anatomy (BV). The role guideline-compliant CPR plays in SV outcomes is unknown. Hypothesis: During pediatric in-hospital cardiac arrest (IHCA), there will be a difference in CPR delivery and outcomes of patients with SV compared to BV anatomy. Methods: Prospective observational cohort from 12 pediRES-Q sites of IHCA in children ≤ 18 years with CPR quality metric data (chest compression (CC) rate, depth, and fraction (CCF)) (Zoll R-Series, Chelmsford, MA). We compared 60-sec CC epoch compliance with 2015 American Heart Association guideline targets defined as: CC rate 100-120/min; depth ≥4.0 cm in <1 yo, ≥5 to ≤6 cm in 1-<18 yo; and CCF ≥0.80. Total guideline compliance was defined as a CC event with ≥ 60% epochs meeting all targets. Metric summaries were reported as median [IQR] and compliance as frequency (%). Differences were assessed using Wilcoxon rank-sum and Fishers exact tests, respectively. Logistic regression assessed for associations with outcomes, including anatomy and proportion of guideline-compliant CPR. Results: From 10/2015 to 3/2019, we analyzed 82 events (> 5 epochs) in patients with CHD. Thirty-seven percent had SV anatomy and more SV patients were post-operative (70% vs 2%). There were no differences in time to first epinephrine dose (1 vs 2 min), shockable rhythm (7% vs 6%), or need for ECMO (27% vs 23%). Total guideline compliance across all ages was not different (SV 10.0% vs BV 5.8%, P=0.67) and not associated with ROSC or survival to hospital discharge (SHD). There was a 75% lower adjusted odds of SHD in 1-<8 yo vs <1 yo. Conclusion: There were no meaningful differences in resuscitative practice or delivery of guideline-compliant CPR in those with SV versus BV anatomy. Guideline-compliant CPR was not associated with outcomes regardless of cardiac anatomy.
