Objectives: Extracorporeal membrane oxygenation to support cardiopulmonary resuscitation (CPR) is increasingly used in children suffering cardiac arrest after cardiac surgery. However, its efficacy in promoting survival has not been evaluated. We compared survival of pediatric cardiac surgery patients suffering in-hospital cardiac arrest who were resuscitated with extracorporeal CPR (E-CPR) to those resuscitated with conventional CPR (C-CPR) using propensity matching.
Design: Retrospective study using multicenter data from the American Heart Association Get With The Guidelines-Resuscitation registry (2008-2020).
Setting: Multicenter cardiac arrest database containing cardiac arrest and CPR data from U.S. hospitals.
Patients: Cardiac surgical patients younger than 18 years old who suffered in-hospital cardiac arrest and received greater than or equal to 10 minutes of CPR.
Interventions: None.
Measurements and main results: Among 1223 patients, 741 (60.6%) received C-CPR and 482 (39.4%) received E-CPR. E-CPR utilization increased over the study period ( p < 0.001). Duration of CPR was longer in E-CPR compared with C-CPR recipients (42 vs. 26 min; p < 0.001). In a propensity score matched cohort (382 E-CPR recipients, 382 C-CPR recipients), E-CPR recipients had survival to discharge (odds ratio [OR], 2.22; 95% CI, 1.7-2.9; p < 0.001). E-CPR survival was only higher when CPR duration was greater than 18 minutes. Propensity matched analysis using patients from institutions contributing at least one E-CPR case ( n = 35 centers; 353 E-CPR recipients, 353 C-CPR recipients) similarly demonstrated improved survival in E-CPR recipients compared with those who received C-CPR alone (OR, 2.08; 95% CI, 1.6-2.8; p < 0.001).
Conclusions: E-CPR compared with C-CPR improved survival in children suffering cardiac arrest after cardiac surgery requiring CPR greater than or equal to 10 minutes.
