Maternal breast milk feeding and length of treatment in infants with neonatal abstinence syndrome

Objectivethe objective of this study is to assess whether infants with neonatal abstinence syndrome (nas), who receive maternal breast milk (bm), have shorter pharmacological treatment durations and lengths of stay compared with formula-fed infants.study designretrospective data analysis from optum neonatal database for infants born between 1 january 2010 and 21 november 2016, who received treatment for nas. clinical characteristics and outcomes were compared between infants who received any amount of bm and those exclusively formula-fed.resultinfants (1738) were analyzed. median length of pharmacological treatment was significantly lower in infants who received any bm (14 days) compared with “no bm” group (17 days, p = 0.04). similarly, median length of hospitalization was significantly reduced in “any bm” group (19 days vs. 20 days), which remained significant after adjustment for confounders (p = 0.01). there was no difference in hospital re-admission rates.conclusionfeeding any bm to infants with nas was associated with both decreased lengths of pharmacological treatment and hospital stay compared with exclusively formula-fed infants.
