Abstract
Background: In premature infants, donor breast milk (DBM) is assumed to provide reduced nutrients vs. mother's own milk (MOM). This study examined calorie and protein delivery when very low birth weight infants were fed fortified MOM or DBM, with a known nutrient composition, relative to established nutrition recommendations and to determine if there were differences between the groups. Methods: A retrospective medical record review was conducted in 29 very low birth weight infants receiving MOM or DBM. Nutrient content of human milk was measured using the Calais Analyzer. Added fortifiers feeding volume, and weight were collected to determine total daily calorie and protein intake. Results: 145 days of enteral feedings among 29 infants were included, 78 (53.8%) from DBM and 67 (46.2%) from MOM. Mean daily fluid intake among infants receiving DBM was significantly higher when compared with MOM, 150.6 ± 7.6 mL/kg vs 146.8 ± 11.3 mL/kg (P =.016). DBM feedings provided 110.1 ± 9.0 kcals/kg/d vs 113.0 ± 21.0 kcals/kg/d from MOM feedings (P =.275). Mean protein intake was similar, 4.1 ± 0.5 g /kg/d on DBM days vs 4.0 ± 0.5 g kg/d on MOM days (P =.162). A total of 46 of 78 DBM days (59.0%) and 30 of 67 MOM days (44.8%) were below the minimum established calorie needs of 110 kcals/kg/day. Conclusions: DBM provides comparable nutrient intake to MOM at a higher enteral feeding volume. However, both types of human milk failed to meet energy needs with standard fortification regimens.
