Objectives: To assess the safety of enteral nutrition (EN) in children on extracorporeal membrane oxygenation (ECMO). To describe nutritional status and the characteristics of the nutritional support in this population.
Methods: A retrospective single-center analysis (2006-2016) including children <18 years on ECMO. Demographic data, nutritional status, characteristics of nutritional support, and development of gastrointestinal (GI) complications were recorded.
Results: One hundred children, with a median age of 9.7 months (interquartile range [IQR] 3.9-63.1) were enrolled. Undernutrition was prevalent among children on ECMO (33.3%) mainly in patients <2 years (P = 0.042). Most patients (64%) received EN at some point during ECMO therapy. EN was administered in the first 48 hours after ECMO initiation (48HEN) to 60.3% of the children.Mortality rate in the Pediatric Intensive Care Unit was lower in patients who received EN as the initial artificial nutrition support (ANS) (37.7 vs 51%, P = 0.005) and in children on 48HEN (34% vs 50%, P = 0.04). In the logistic regression analysis, duration of ECMO support and low cardiac output indication were the only factors associated with mortality.Although most patients on ECMO (45%) developed digestive complications, they were mostly mild, being constipation the most prevalent. In the logistic regression analysis, EN was not associated with an increase in GI complications (P = 0.09). Only three patients developed intestinal ischemia (one without EN and two on EN).
Conclusions: Undernutrition is prevalent among children on ECMO, mainly in infants <2 years. EN is not associated with severe gastrointestinal complications or higher mortality in these children.
