minimal enteral nutrition
Small volumes of breast milk or formula given to very premature infants to stimulate gut development and function while providing minimal caloric intake.
Full Definition
Minimal enteral nutrition (MEN), also known as trophic feeding or gut priming, involves administering very small volumes (typically 10-20 mL/kg/day) of breast milk or formula to very low birth weight and extremely premature infants. The primary purpose is not nutritional but rather to stimulate gastrointestinal tract development, promote gut hormone release, enhance gut motility, and establish normal bacterial colonization. MEN may help reduce the risk of necrotizing enterocolitis and feeding intolerance while facilitating the transition to full enteral nutrition. This practice is typically initiated within the first few days of life, even in critically ill infants who are receiving most of their nutrition parenterally.
Usage
Usage note: Often abbreviated as MEN; distinguish from full nutritional feeding
