Late Preterm Steroids Are Here

Medical students on their OBGYN rotations have long memorized the corticosteroid rule: If delivery is imminent in the next week, before 34 weeks gestational age, give corticosteroids for lung maturity. Two doses, 24 hours apart have been shown to improve respiratory outcomes in strong, randomized clinical trials. However, what about the 70% of preterm deliveries that occur between 34 weeks and 36 weeks 6 days? Do these infants benefit from corticosteroids? The Society for Maternal Fetal Medicine is spreading the word about the new ALPS study on this very topic.
