RESUMO
OBJECTIVE: To evaluate effects of gastric lavage with mother's milk starting 4 hours after birth, in hospitalized preterm newborns otherwise on exclusive parenteral fluids. METHOD: Study design: Randomized controlled trial. Sick preterm babies were assigned to receive in addition to parenteral fluids, either gastric lavage with mother's milk within 4 hours of birth and subsequently every 3 hours till tolerance of nutritive enteral feeds (intervention or BML group, n = 40), or remain nil per orally till tolerance of nutritive enteral feeds (control or NPO group, n = 40). The main outcome was the mean number of days of parenteral fluids till successful tolerance of nutritive enteral feeds. They were also evaluated for mean duration of hospital stay, development of new complications, and mortality. RESULT: Despite sicker babies in the BML group at baseline, the mean duration of exclusive parenteral fluid was significantly less (P = 0.003) in BML (3.9 +/- 1.5 days as compared to 5.4 +/- 2.6 days in NPO). In the NPO group 60% of the babies stayed longer than 3 weeks in hospital compared to only 30% in the BML group. The risk of development of new complication after randomization was also significantly less in BML group [RR 0.61 (95% CI 0.40-0.95) (P=0.03)]. Incidence of sepsis was 44% less in BML group [30% in BML, 55% in NPO group; RR 0.58; 95% CI 0.35-0.97; P = 0.02]. On multivariate logistic regression, BML group, birth weight and absence of complication at the time of hospitalization were strong predictors of improved outcome. There was no difference in mortality between 2 groups. CONCLUSION: This study showed that early exposure to even small amounts of mother's milk in sick preterm neonates significantly reduced the days on parenteral fluids, risk of sepsis and the duration of hospital stay without any adverse effect.
