The use of corticosteroids is one of the most important therapies used in prenatal care to improve the outcomes of the newborn by reducing the rates of respiratory distress syndrome, intraventricular hemorrhage, necrotizing enterocolitis and contribute to the survival of extreme preterm infants. In addition to steroids, the use of magnesium sulfate protects the newborn from cerebral palsy in cases of extreme preterm births. All of these conditions increase perinatal morbidity/mortality and are related to potentially serious illness in the newborn requiring care in neonatal intensive units. The use of corticosteroids and magnesium sulfate are measured to prevent unfavorable outcomes of premature newborns admitted to a neonatal intensive care unit. The incidence of twin pregnancy is only 3% of all live births, however, it accounts for 15% of extreme preterm births less than 32 weeks. Women with multiple pregnancies are six times more likely to terminate the pregnancy before term compared to single pregnancies. The determination of the use of corticosteroids in multiple pregnancies remains conflicting due to the scarcity of studies related to this group. Therefore, this chapter aims to evaluate the effectiveness of the use of corticosteroids in twin pregnancies in early and late preterm, evaluating its outcome in respiratory morbidity and metabolic aspects of the newborn.
