A comparison of short- and long-term prognoses between cases with and without antenatal corticosteroid administration in late preterm delivery: a nationwide population-based study

Dexamethasone administration in late preterm infants was associated with a decreased risk of transient tachypnea compared with no corticosteroid administration but this effect was not observed with betamethasone administration. However, antenatal corticosteroid administration in the late preterm period did not lower the risk of other respiratory complications nor increase the risk of hypoglycemia, with no effect on neurodevelopment regardless of the type used.
