Necrotizing Enterocolitis - Prevention

Prevention

Once a child is born prematurely, thought must be given to decreasing the risk for developing NEC. Toward that aim, the methods of providing hyperalimentation and oral feeds are both important. A recent study, by researchers in Peoria, IL, published in Pediatrics in 2008, demonstrated that using a higher rate of lipid (fats and/or oils) infusion for very low birth weight infants in the first week of life resulted in zero infants developing NEC in the experimental group, compared with 14% with NEC in the control group (They started the experimental group at 2 g/kg/d of 20% IVFE and increased within two days to 3 g/kg/d; Amino acids were started at 3 g/kg/d and increased to 3.5).

Neonatologists at the University of Iowa NICU reported on the importance of providing small amounts of trophic oral feeds of human milk starting ASAP, while the infant is being primarily fed intravenously, in order to prime the immature gut to mature and become ready to receive greater oral intake. Human milk from a milk bank or donor can be used if mother's milk is unavailable. The gut mucosal cells do not get enough nourishment from arterial blood supply to stay healthy, especially in very premature infants, where the blood supply is limited due to immature development of the capillaries, so nutrients from the lumen of the gut are needed.
