RESUMO
BACKGROUND: Mother's own milk (MOM) improves in-hospital outcomes for preterm infants. If unavailable, donor milk (DM) is often substituted. It is unclear if DM vs. formula to supplement MOM is associated with improved in-hospital outcomes in term/late preterm surgical infants with gastroschisis or intestinal atresia. METHODS: This retrospective study included infants born ≥33 weeks gestational age (GA) with a birth weight of >1500 g who were admitted to a quaternary neonatal intensive care unit (NICU). Using Chi square and Mann-Whitney u testing, we compared hospital outcomes (length of stay, parenteral nutrition and central line days) before and after a clinical practice change to offer DM instead of formula in this surgical population. RESULTS: Baseline characteristics were similar between eras for the 140 infants (median GA 37 weeks). Fewer infants in DM era were receiving formula at discharge (50.0% vs. 31.4%, p = 0.03). In sub-analyses including only small bowel atresia and gastroschisis infants, the median length of stay (35 vs. 25, p < 0.01) and the central line days (28 vs. 20, p < 0.01) were lower in the DM era. CONCLUSION: In this retrospective study, offering DM instead of formula was associated with less formula feeding at discharge, and in infants with gastroschisis or small bowel atresia, shorter length of stay and central line days.
