Expressed breast milk analysis: an innovative tool in optimizing protein energy ratio and avoiding protein deficit after preterm birth (635.3)

Background: EBM protein content is highly variable between mothers and often below published levels. Current EBM fortification for preterm infants assumes equal EBM protein and focuses on increasing caloric intake. This approach may result in significant protein deficit over time and suboptimal P/E ratio. Objective: Determine if EBM analysis identifies a significant protein deficit after preterm birth and if individualized EBM protein fortification optimizes P/E ratio. Methods: The Julie Z7 milk analyzer (Scope Electric Ltd, Germany) was used to determine EBM protein content at day of life (DOL) 10 and every 2 weeks from mothers of preterm infants born at 24-29 6/7 weeks gestation. Using results of the milk analysis, anticipated protein deficit was compared to presumed protein intake based on published EBM protein levels (1.4 g/dl). P/E ratio was calculated for both standard and individualized fortification. Results: EBM protein content in 26 preterm infants receiving 150 ml/kg/day of EBM was 1.97 g ± 0.0...
