  • Introduction An unexpected increase in the incidence of necrotising enterocolitis (NEC) cases was observed in our hospital. Just in case, our feeding policy could be responsible, it was decided to conduct a systematic review and develop a clinical guideline regarding enteral nutrition of very low birth weight infants (VLBW).

    Objective To assess the impact of the new feeding protocol in the incidence of NEC.

    Method A “before” (2011) and “after” (May 2012 - April 2013) study was performed on the new feeding protocol. This included initiation of enteral feeding in the absence of haemodynamic problems, a trophic feeding period of 5-7 days, and subsequent increments of 20-30ml/kg/day, of breast milk/donor human milk from the beginning. Probiotics were not administered. Primary outcome: incidence of NEC II 2 Bell's stage. Secondary outcomes: focal intestinal perforation, overall mortality and mortality due to NEC, nosocomial sepsis; weight at 28 days and 36 weeks; % of infants with weight Results Of the 270 VLBW infants, 155 were included in the “before” group, and 115 in the “after” group. NEC significantly decreased (12/155 vs 1/115, P=.008). A decrease in mortality rate was also observed (17.4% vs 7.8%, P=.02). In four cases NEC was part of the sequence of events that led to death in the first cohort, with none in the second. There was no difference in the incidence of focal intestinal perforation or of the other secondary variables analysed.

    Conclusions Implementation of an evidence-based enteral feeding protocol leads to a decrease in incidence of NEC, without increasing hospital stay or the incidence of sepsis.
