Cervical ripening with glyceryl trinitrate resulted in fewer episodes of tachysystole, but there were significantly more minor side effects. It can be used for cervical ripening at term, but it was not as effective as PGE2.
Vaginal misoprostol was effective for the second trimester pregnancy termination but the safety of misoprostol in the scarred uterus cannot be assumed from this study. A large series is needed to reach the power to see the difference.
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.
