Abstract 9588: Higher Survival With the Use of Extracorporeal Cardiopulmonary Resuscitation Compared With Conventional Cardiopulmonary Resuscitation in Children Undergoing Cardiac Surgery: Analysis of the Get With the Guidelines Registry©

Abstract

Introduction: Extracorporeal cardiopulmonary resuscitation (E-CPR) has been increasingly utilized during in-hospital arrest in postoperative pediatric cardiac surgical patients. Despite this and the significant associated mortality, few pediatric multicenter analyses have evaluated if E-CPR increases survival for in-hospital cardiac arrest compared with conventional cardiopulmonary resuscitation (C-CPR). Methods: Children <18 years in the Get with the Guidelines-Resuscitation Registry© suffering in-hospital cardiac arrest following cardiac surgery who received ≥10 minutes of CPR between January 2008 and December 2020 were included. We compared patient factors, pre-arrest comorbid conditions, and survival to hospital discharge for E-CPR and C-CPR groups. Results: Among 1219 patients from 56 institutions, 483 patients (39.6%) received E-CPR. Nearly 75% (910/1219) of patients were <1 year of age with 39% (477/1219) under 1 month. Older patients were more likely to receive E-CPR (p=0.004). E-CPR utilization increased over the study period (p<0.001). Non-Hispanic White patients accounted for almost half of the population (575/1219) and were also more likely to receive E-CPR (p=0.044) compared to other races/ethnicities. Patients with cyanotic cardiac malformations (p=0.005), congestive heart failure prior to admission (p=0.007), and hypotension prior to arrest (p=0.014) were also more likely to receive E-CPR. Unadjusted survival of the index CPR event (98% vs. 63%, p<0.001) and to hospital discharge (47% vs 39%, p=0.007) were both higher in the E-CPR compared to C-CPR group. Conclusions: In a large, multicenter study of pediatric cardiac surgical patients suffering in-hospital arrest, we found that E-CPR is commonly used and had significantly higher survival to hospital discharge compared with C-CPR. E-CPR is an important rescue strategy for children with heart disease and centers performing cardiac surgery should develop E-CPR programs.
