Effect of vaginal washing before Misoprostol insertion on cervical ripening before induction of labor: A randomized single-blind clinical trial.

Background: Vaginal pH is acidic in pregnancy, but there is no information about pH changes in pregnancy, and contradictory results have been reported from the effectiveness of Misoprostol at different vaginal pH. This study aimed to evaluate the effect of vaginal washing before Misoprostol insertion on cervical ripening before induction of labor in comparison with the control group.

Methods: This randomized single-blind clinical trial was performed on 148 pregnant women who were candidates for induction of labor.
