The purpose of this study is to investigate the efficacy of Indomethacin compared to Magnesium Sulfate (MgSO4) in reducing neonatal morbidity through a prospective double blind randomized clinical trial. The specific aim of the project is to test the hypothesis that Indomethacin, compared to MgSO4, will decrease the proportion of neonates diagnosed with major complications or death.
