Administering Intravenous Fluid in the Immediate Postpartum Period Minimizes Ultimate Formula Feeding.

Background: Human milk is the optimal form of nutrition for infants. Interventions associated with a decreased rate of exposure to infant formula are of benefit. We hypothesized that intravenous (IV) fluids could be associated with a reduction of infant formula when infants are separated from their mother. Methods: Retrospective chart review of term infants admitted to Rady Children's Neonatal Intensive Care Units (NICUs) for possible sepsis who received antibiotic treatment but did not develop sepsis. IV fluid use and formula exposure were analyzed. Results: Six hundred twenty-eight infants met the inclusion criteria. Around 25.6% received IV fluids and 74.4% did not. IV fluid administration was associated with a significantly reduced chance of formula exposure while in the NICU (odds ratio: 0.694, 95% confidence interval: 0.484-0.993; * p  = 0.046). Conclusion: This retrospective chart review found that infants transferred to the NICU and separated from their mothers due to chorioamnionitis exposure who received IV fluids were significantly less likely to receive any infant formula than infants who were not administered IV fluids.
