Betamethasone therapy in preterm delivery is intended to promote what?

• A. To promote fetal lung maturity
• B. To treat maternal infection
• C. To accelerate labor
• D. To prevent postpartum hemorrhage

Answer: (A)

Betamethasone given when preterm birth is expected acts to accelerate the fetus’s lung development by boosting surfactant production. Surfactant lines the alveoli and lowers surface tension, helping the lungs expand and function after birth. The corticosteroid stimulates the fetal type II pneumocytes to produce surfactant phospholipids, improving the lung’s maturity as reflected in a rising lecithin (phosphatidylcholine) level and better L/S ratio. This leads to a lower risk and severity of respiratory distress syndrome in preterm infants and improves overall neonatal outcomes. It isn’t used to treat maternal infection, to speed up labor, or to prevent postpartum hemorrhage—the purpose is to promote fetal lung maturity to enable better breathing after birth.
