Nutrition Provision in Children with Heart Disease on Extracorporeal Membrane Oxygenation (ECMO).

Abstract

Nutrition provision for children with heart disease supported with extracorporeal membrane oxygenation (ECMO) involves nuanced decision making. We examined nutrition provision while on ECMO in the CICU and the relationship between energy and protein adequacy and end organ function as assessed by pediatric sequential organ failure assessment (pSOFA) scores in children with heart disease supported with ECMO. Children (≤ 21 years-old) with congenital or acquired heart disease who received ECMO in the cardiac intensive care unit were included. There were 259 ECMO runs in 252 patients over an 8-year study period (2013-2020). Median energy delivery and adequacy were 26.1 [8.4, 45.9] kcal/kg/day and 58.3 [19.8, 94.6]%, respectively. Median protein delivery and adequacy were 0.98 [0.36, 1.64] g/kg/day and 35.7 [13.4, 60.3]%, respectively. pSOFA increased by a median of four points during the ECMO run. Change in pSOFA score was not associated with energy or protein adequacy (p = 0.46 and p = 0.72, respectively). Higher energy and protein adequacy-from parenteral nutrition-correlated with increased hospital-acquired infections (HAIs, p = 0.031 and p = 0.003, respectively). Achieving nutritional adequacy was dependent on the use of parenteral nutrition. Similar clinical outcomes with regard to end organ function but with an increased incidence of HAIs suggests the need to explore the role of optimal enteral nutrition delivery on ECMO.
