Intestinal Lavage to Promote Enteral Feeding and Prevent Necrotizing Enterocolitis in Extremely Preterm Infants

Specially trained pediatric surgeon will administer 10ml/kg pre-warmed (37oC) normal saline via a single-use rectal tube of size 6FR twice per day, aiming at a depth of maximum 10 cm/kg, starting after randomization and not later than 24 hours of age, and continued until full enteral nutrition of 170ml/kg/day is achieved or NEC diagnosis (Bell stage II or more) is established, which one comes first. However, the intervention will be applied at a maximum of 2 weeks from birth.
