Abstract

Objective: To compare outcomes of extremely low birth weight (ELBW) infants exposed to no antenatal steroids (ANS); incomplete ANS and complete course of ANS at varying intervals prior to delivery. Methods: A retrospective review was performed on 169 ELBW infants with ANS exposure at varied dose-intervals. The odds of mortality, intraventricular hemorrhage (IVH) and bronchopulmonary dysplasia (BPD) were compared between Group 1, infants born without ANS exposure, Group 2, infants born after one dose of ANS, Group 3, infants born after two doses of ANS given within a week, and Group 4, infants born after two doses of ANS >7 days prior to delivery. Results: Mortality and IVH were significantly lower in Groups 3 (30% and 10%) and 4 (15% and 30%), compared to Groups 1 (56% and 69%) and 2 (56% and 38%). Increasing gestational age and exposure to complete course of ANS were significantly associated with decrease in mortality, BPD/mortality and IVH. Infants who received one dose of ANS had significantly lower incidence of severe IVH compared to infants without ANS exposure. Conclusions: Beneficial impact of ANS on mortality and composite BPD/mortality is evident only after a complete course and persists even with its administration beyond a week from delivery.
