BackgroundRecent advances in extracorporeal membrane oxygenation (ECMO) have led to increasing interest in its use during cardiopulmonary resuscitation (CPR). However, decisions regarding extracorporeal CPR (ECPR) in children are difficult as a result of limited studies, especially in Asia Pacific. The objective of this study was to investigate trends in survival and demographic details for children with ECPR in Asia Pacific recorded in the Extracorporeal Life Support Organization (ELSO) registry from 1999 to 2016 and identify the risk factors associated with in-hospital mortality.MethodsThe data of children younger than 18 years of age who received ECPR over the past 18 years in Asia Pacific were retrospectively analyzed. The data were extracted from the ELSO registry and divided into two 9-year groups (Group 1: 1999-2007 and Group 2: 2008-2016) to assess temporal changes using univariate analysis. Then, univariate and multiple logistic regression analyses were performed between survivors and nonsurvivors to identify factors independently associated with in-hospital mortality.ResultsA total of 321 children were included in final analysis, with an overall survival rate of 50.8%. Although survival rates were similar between Group 1 and Group 2 (43.1% vs. 52.5%, χ2 = 1.67, P = 0.196), the median age (1.7 [0.3, 19.2] months for Group 1 vs. 5.6 [0.8, 64.9] months for Group 2, t = -2.93, P = 0.003) and weight (3.7 [3.0, 11.5] kg for Group 1 vs. 6.0 [3.4, 20.3] kg for Group 2, t = -3.14, P = 0.002) of children increased over time, while the proportion of congenital heart disease (75.9% for Group 1 vs. 57.8% for Group 2, χ2 = 6.52, P = 0.011) and cardiogenic shock (36.2% for Group 1 vs. 7.2% for Group 2, χ2 = 36.59, P < 0.001) decreased. Patient conditions before ECMO were worse, while ECMO complications decreased across time periods, especially renal complications. Multiple logistic regression analysis of ECMO complications showed that disseminated intravascular coagulation (DIC), myocardial stunning, and neurological complications were independently associated with increased odds of hospital mortality.ConclusionsThe broader indications and decreased complication rates make EPCR to be applicated more and more extensive in children in Asia Pacific region. ECMO complications such as myocardial stunning are independently associated with decreased survival.
