[Reduction in necrotising enterocolitis after implementing an evidence-based enteral nutrition protocol in very low birth weight newborns]. / Reducción de la enterocolitis necrosante tras la introducción de un protocolo de alimentación enteral basado en la evidencia en recién nacidos de muy bajo peso.

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
