Nutritional implications for the patient undergoing extracorporeal membrane oxygenation

Area of Science:

• Critical Care Medicine
• Nutritional Science
• Cardiopulmonary Support

Background:

• Extracorporeal membrane oxygenation (ECMO) is a life-support intervention for severe cardiovascular or respiratory failure.
• Patients on ECMO experience hypermetabolism, protein catabolism, and negative energy balance.
• Optimal nutritional support is crucial but challenging in this complex patient population.

Purpose of the Study:

• To review the current literature on nutritional support strategies for adult patients undergoing ECMO.
• To identify challenges and gaps in knowledge regarding nutritional therapy in ECMO.
• To inform clinical practice in the absence of specific guidelines.

Main Methods:

• Literature search of current research on nutritional support in adult ECMO patients.
• Synthesis of findings related to metabolic demands and nutritional interventions.
• Identification of factors complicating nutritional therapy delivery.

Main Results:

• Adult ECMO patients have significantly increased metabolic and catabolic rates.
• Achieving adequate nutritional intake is frequently hindered by clinical factors.
• There is a notable absence of evidence-based guidelines for nutritional support in this cohort.

Conclusions:

• Nutritional support is a critical, yet under-addressed, component of ECMO management.
• Further research is needed to develop evidence-based guidelines for nutritional therapy in adult ECMO patients.
• A multidisciplinary approach is essential for optimizing nutritional care during ECMO.
