Evaluation of the effect of antenatal betamethasone on neonatal respiratory morbidity in early-term elective cesarean.

Compared with vaginal delivery, early-term cesarean section (CS) is associated with an increased risk of neonatal respiratory morbidity. Given the role of steroids in lung maturation in preterm labor, few studies have investigated their effects on early-term delivery. Therefore, this study aimed to investigate the effect of antenatal betamethasone on neonatal respiratory morbidity in early-term elective cesarean (37-38 weeks and 6 d).

Evaluation of the effect of antenatal betamethasone on neonatal respiratory morbidities in late preterm deliveries (34-37 weeks).

Since late preterm neonates (34-36 weeks) are more at risk of respiratory morbidities, the present study was conducted to evaluate the effect of antenatal betamethasone on neonatal respiratory morbidities in women with late preterm delivery. This randomized clinical trial was performed on 240 women with single pregnancy that was at high risk of late preterm delivery (34-37 weeks). The patients were randomly assigned to either betamethasone (intramuscular injection of 12 mg of betamethasone in two doses with an interval of 24 hours) or the control group.
