What is the recommended corticosteroid timing for fetal lung maturation in threatened preterm birth?

• A. Administer between ~24 and 34 weeks gestation.
• B. Administer after 37 weeks.
• C. Administer before 20 weeks.
• D. Administer after delivery.

Answer: (A)

Antennatal corticosteroids are given to accelerate fetal lung maturation when there’s a real risk of preterm birth. They boost surfactant production, which lowers the chances of respiratory distress syndrome and other complications after birth. The best timing is when delivery is likely within the next 7 days, typically between about 24 and 34 weeks of gestation. Starting treatment in this window allows the fetus to gain the respiratory benefits before birth. Administering after 37 weeks provides little to no respiratory advantage, and giving before 24 weeks isn’t helpful because fetal lungs aren’t ready for this maturation to occur. After delivery, steroids won’t help the unborn baby’s lungs either.
