The Effect of Using Dexamethasone Tablets Vaginally for Improving Cervical Bishop Score in Nulliparous Pregnant...

Cervix ripening and labor induction are common interventions in obstetrics. For optimal maternal health, labor may be induced under certain situations to improve fetal survival outcomes. Labor induction of an unripe cervix can lead to complications; therefore, several approaches can facilitate the ripening process.

This randomized clinical trial was a triple-blind study that involved 84 pregnant nulliparous women enrolled between October 2019 and June 2021 in the labor ward of Kamali Hospital, Karaj, Iran. The pregnant women in the study underwent labor induction and were randomized into 2 groups: 1 group received vaginal dexamethasone and the other group was given a placebo.

There was no significant difference between the groups regarding maternal age, demographic characteristics, and initial Bishop score. The median second Bishop score (6 hours after intervention) was 3.5 in dexamethasone recipients and 3 in placebo recipients (P = 0.48). The median labor latent phase duration was 4 hours in dexamethasone recipients and 5 hours in placebo recipients (P = 0.57).

This randomized clinical trial demonstrated that administering dexamethasone tablets vaginally did not significantly improve cervical Bishop scores. (Curr Ther Res Clin Exp. 2023; 84:XXX-XXX). ClinicalTrials.gov identifier: NCT05070468.
