Nutrition Provision in Pediatric Extracorporeal Membrane Oxygenation: Evidence, Challenges, and Clinical Considerations.

BACKGROUND/OBJECTIVES: Nutritional support is a critical yet challenging aspect of care for pediatric patients requiring extracorporeal membrane oxygenation (ECMO). Malnutrition is prevalent in this population and is associated with worse clinical outcomes. This review synthesizes current evidence on nutritional strategies for pediatric ECMO patients, emphasizing assessment methods, feeding routes, challenges, and clinical outcomes.

METHODS

A literature review was conducted using PubMed, Scopus, and Web of Science to identify relevant studies published between January 2010 and 2025. Keywords included "pediatric ECMO", "nutrition", "enteral feeding", and "parenteral nutrition". Studies addressing nutritional assessment, enteral and parenteral feeding practices, and their impact on clinical outcomes were included.

RESULTS

Malnutrition is a significant risk factor for morbidity and mortality in ECMO patients, yet nutritional support remains highly variable. While enteral nutrition (EN) is preferred, feeding intolerance and gastrointestinal dysfunction often necessitate parenteral nutrition (PN). Early EN initiation, even at trophic levels, is associated with improved gut integrity and outcomes. However, achieving full nutritional goals enterally remains a challenge, particularly in neonates. PN remains essential in cases of feeding intolerance but is linked to hepatic dysfunction and metabolic imbalances.

CONCLUSIONS

Optimizing nutritional support in pediatric ECMO patients requires individualized assessment and a structured approach to enteral and parenteral feeding. Further research is needed to establish standardized feeding protocols and determine the optimal timing and composition of nutritional support to improve outcomes.
