Objective. To determine if antepartum administration of magnesium sulfate affects the Score for Neonatal Acute Physiology (SNAP). Methods. We reviewed a database of consecutive preterm admissions to our neonatal intensive care unit over a 12-month period. Information on delivery indication, magnesium sulfate use, betamethasone administration, neonatal SNAP scores, neonatal serum magnesium levels, and other data was collected. Data was analyzed by Chi-square, Student t-test, and multiple linear regression with P < 0.05 considered significant. Results. During the study period, 221 cases fulfilled inclusion and exclusion criteria. Multiple regression revealed a significant association between antepartum magnesium use and improved SNAP scores after controlling for gestational age, glucocorticoid use, chorioamnionitis, and birthweight (SNAP score reduction = -2.25 ± 0.78, P = 0.005). Conclusions. Antepartum administration of magnesium sulfate results in a significant improvement in the neonatal SNAP score. These results suggest that antepartum magnesium sulfate may be protective, or at least not detrimental to the newborn infant.
