Background & Objective: Preterm birth is the most important cause of neonatal mortality and morbidity. Finding the best treatment regimen, of antenatal corticosteroids, has been under serious concern. To compare the efficacy of intravascular versus intramuscular betamethasone phosphate on neonatal outcomes in the cases of imminent preterm birth.Materials & Methods: A double-blind randomized clinical trial was performed on 136 eligible pregnant women with gestational age of 26- 34 weeks and imminent preterm birth (delivery within 24 hours). They were randomly assigned into two groups. Group A received intramuscular betamethasone phosphate, and group B received a similar dose of betamethasone phosphate intravenously. Women were followed up to delivery, and their neonatal outcomes were compared.Results: Women of the two groups (68 women in each group), did not show a significant difference in maternal age, BMI, gravidity and parity, gestational age at the time of admission and delivery, history of miscarriage and assisted reproductive techniques, delivery route, sex and weight of newborns, and Apgar score in minutes 1 and 5. The need for NICU admission, duration of hospitalization, neonatal respiratory distress syndrome, surfactant requirement, and intubation were lower in the IV betamethasone group. There were no significant differences between the two groups according to necrotizing enterocolitis, intraventricular hemorrhage, and neonatal death.Conclusion: Using IV betamethasone, in cases where there is no enough time to complete the 24-hour betamethasone course due to the possibility of impending delivery, may reduce neonatal complications due to quicker onset of action.
