This study found that administering the first dose of antenatal corticosteroids (ACS) between 48 hours and 7 days before delivery was associated with a lower risk of perinatal mortality and respiratory distress syndrome (RDS) compared to administering the first dose less than 48 hours before delivery.
Background: Uncertainty exists regarding the ideal interval between the administration of antenatal corticosteroids (ACS) and delivery. The study's objective was to assess the risks of perinatal mortality and respiratory distress syndrome (RDS) among preterm neonates whose mothers gave birth within 48 h of the administration of ACS and those whose mothers gave birth between 48 h and 7 days.Methods: The study design was a secondary analysis of data from an observational prospective chart review study that was carried out in Tanzania in 2020. Preterm infants born to mothers who got at least one dose of ACS between 28 and 34 weeks of pregnancy were included.Results: A total of 346 preterm neonates (294 singletons and 52 twins) were exposed to ACS. Compared to infants born 48 h following the first dose of ACS, those exposed to the drug between 48 h and 7 days had significantly decreased rates of perinatal mortality and RDS. Multivariable analysis revealed that infants exposed ACS between 48 h and 7 days prior to delivery had lower risk of perinatal mortality (aRR 0.30, 95% CI 0.14-0.66) and RDS (aRR 0.27, 95% CI 0.14-0.52).Conclusion: The first dose of ACS given between 48 h and 7 days before delivery was associated with a lower risk of perinatal mortality and RDS than when the first dose was given <48 h before delivery. To improve neonatal outcomes, healthcare providers should consider administering ACS to mothers at the appropriate time.
