 There is a substantial body of evidence that the administration of corticosteroids to patients deemed to be at risk for preterm delivery delivery prior to 37 weeks gestation decreases the risk of respiratory distress syndrome, intraventricular hemorrhage, and neonatal death. Current recommendations from the National Institute of Health NIH and the American College of Obstetricians and Gynecologists ACOG are that patients with pregnancies that are between 24-34 weeks gestation deemed at risk for preterm delivery receive antenatal corticosteroids. The recommended dosing is two doses of betamethasone 12 mg given 24 hours apart as an intramuscular injection. Alternatively, dexamethasone 6 mg given intramuscularly every 6 hours for 4 doses may be administered. Betamethasone is used preferentially in our institution.
