Dexamethasone administration before planned CS at term, as compared to routine management without antenatal steroids, was not associated with a statistically significant reduction in the incidence of admission to NICU with respiratory morbidity.

Planned cesarean section (CS) has been found to lead to significantly higher rates of overall neonatal respiratory morbidity than intended vaginal delivery. Various etiologies for these complications have been proposed such as iatrogenic prematurity with surfactant deficiency and an absence of hormonal and physiological changes necessary for proper lung functioning in infants delivered by planned CS.
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.
