Steroid study seeks clues to prevent preemie lung disease

This study looked at how a steroid called betamethasone, given to pregnant women to help their babies' lungs, moves from mother to baby. Researchers wanted to see if the amount that reaches the baby affects the risk or severity of hyaline membrane disease, a serious breathing problem in premature newborns. The study included 127 pregnant women and their babies. The goal was to better understand how this medicine works, not to test a new treatment.
