BACKGROUND: Postprandial rise of plasma essential amino acids (EAA) determines the anabolic effect of dietary protein. Disturbed gastro-intestinal function could impair the anabolic effect of enteral nutrition in critically ill patients. Our aim was to investigate the EAA response following an enteral nutrition bolus in critically ill patients and its relation to small intestinal function. METHODS: Twenty-one mechanically ventilated patients and nine healthy controls received a bolus containing 100 mL of a formula feed (Ensure) and 2 g of 3-O-Methyl-d-Glucose (3OMG) via post-pyloric feeding tube. Fasting and post-prandial plasma concentrations of EAA, 3-OMG, total bile salts and the gut-rele..View full abstract
