Overwhelming adenovirus infection requiring extracorporeal membrane oxygenation (ECMO) support carries a high mortality in pediatric patients. The objective of this study was to retrospectively review data from the Extracorporeal Life Support Organization (ELSO) registry for pediatric patients with adenovirus infection and define for this patient cohort: 1) clinical characteristics, 2) survival to hospital discharge, and 3) factors associated with mortality before hospital discharge. In this retrospective registry study, pediatric patients with adenovirus infection requiring ECMO support identified in an international ECMO registry from 1998 to 2009 were compared for clinical characteristics (demographics, pre-ECMO variables, and complications on ECMO) between survivors and nonsurvivors to hospital discharge. ⋯ ECMO complications independently associated with in-hospital mortality were presence of pneumothorax (OR, 3.57; 95% CI, 1.19-10.7), pH less than 7.2 (OR, 5.94; 95% CI, 1.04-34.1), and central nervous system hemorrhage (OR, 25.36; 95% CI, 1.47-436.7). In this retrospective cohort study of pediatric patients with adenovirus infection supported on ECMO, survival to hospital discharge was 38% but was much lower in neonates. Neonatal presentation, degree of acidosis, sepsis, and increased PIP are factors present before decisions are made regarding a trial of ECMO, whereas pneumothorax and brain hemorrhage were ECMO-related complications independently associated with mortality.

The objective of this study was to identify types of neonatal diseases associated with prolonged (≥21 days) extracorporeal membrane oxygenation (ECMO), characteristics of survivors and nonsurvivors among those requiring prolonged ECMO, and factors associated with mortality. Data were obtained from the Extracorporeal Life Support Organization registry over the period from January 1, 1998, through December 31, 2011, for all neonates (age <31 days), with respiratory failure as the indication for ECMO. The primary outcome was survival to hospital discharge. ⋯ Many of these cases involve CDH. Complications are common with prolonged ECMO, but only receipt of inotropes was shown to be independently associated with mortality. This report may help guide clinical decision making and family counseling for neonates requiring prolonged ECMO support.
