Early versus Late Trophic Feeding in Very Low Birth Weight Preterm Infants

Abstract

Objective: Improved survival of preterm infants, beneficial effects of trophic feeding and limited data on timing management of enteral feeding for very low birth weight preterm infants requires more researches to determine the exact starting time and increased volumes. This study aims to compare early (72h) trophic feeding with respect to important neonatal outcomes. Methods: In a cohort study from September 2007 to October 2008, a total of 170 preterm infants (1000-1500 gram, 26-31 weeks) consisting of 125 who received trophic feeding enterally within the first 48 hours of birth (early group) and 45 fed enterally after 72 h0urs (late group), without major congenital birth defects and severe asphyxia entered the study. Bolus feeding was started in both groups at 1-2 cc/kg every 4-6 hours of human milk or preterm infant formula and was advanced 1-2 cc/kg/day if tolerated along with parenteral nutrition. Feeding intolerance, possibility of necrotizing entrocolitis (NEC), episodes of sepsis, body weight, length of NICU stay, and duration of parenteral nutrition were assessed serially. Findings: There were no statistically significant differences in the clinical and maternal characteristics of infants in the two groups. The time to gain birth weight (13.75±5.21 vs 20.53±6.31 (P
