What is the primary goal of minimal enteral nutrition (trophic feeds) in ELBW/very preterm infants?

• A. To provide full caloric intake.
• B. To prevent infection.
• C. Small-volume feeds to stimulate gut maturation (e.g., 10–20 mL/kg/day) with the goal of promoting intestinal development, reducing NEC risk, and facilitating eventual full feeds.
• D. To replace TPN.

Answer: (C)

The main idea is that the very preterm gut is immature, so giving tiny amounts of milk aims to gently wake up and mature the gut rather than meet all calories right away. These small-volume feeds, started at about 10–20 mL/kg/day, stimulate intestinal growth, motility, and hormone and enzyme activity, helping the gut develop its barrier and coordination. As the gut matures, it becomes better at handling feeds, which lowers the risk of necrotizing enterocolitis and makes it possible to progress to full enteral feeding. Trophic feeds also help reduce reliance on parenteral nutrition by preparing the gut for longer-term enteral nutrition. So the goal is to promote gut development and lower NEC risk while paving the way to full feeds, not to supply full calories or replace TPN from the start.
