Retrospective studies suggested that the risk of cerebral palsy and intraventricular hemorrhage (IVH) in extremely premature infants of mothers given magnesium sulfate (MgSO4) may be reduced. The purpose of this study was to examine the effects of MgSO4 exposure on adverse outcomes in extremely low birth weight (ELBW) infants. For infants included in the NICHD Neonatal Research Network Generic Database, data were prospectively collected on maternal/infant conditions and MgSO4 exposure (including indications, timing and duration of exposure).
