When a baby is born prematurely, their lungs may not be fully developed, leading to respiratory issues. Antenatal corticosteroids, like betamethasone and dexamethasone, are administered to pregnant women at risk of preterm delivery to boost the baby’s lung maturity and reduce complications such as Respiratory Distress Syndrome (RDS). These steroids help the baby produce surfactant, which keeps the lungs open and improves breathing after birth. Dr. Rachel Pasquesi will discuss how these medications work and their benefits.
