Antenatal corticosteroid (ACS) treatment is recommended for all women who are at risk of preterm birth before 34 weeks’ gestation and reduces neonatal death, respiratory distress syndrome, intraventricular hemorrhage, and other adverse events in preterm infants. Data regarding the effects of ACS on extremely preterm infants is limited. This study aimed to investigate the impact of the administration-to-birth time interval on survival in extremely preterm infants.
Although this study indicates that repeat exposure to antenatal corticosteroids may have an impact on aspects of executive functioning, it does not provide support for the prevailing concern that such fetal exposure will have a major adverse impact on cognitive functions and psychological health later in life.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
