This is a randomized prospective trial of two mechanical methods of pre-induction cervical ripening agents.


Term, low risk patients requesting elective induction of labor who desire pre-induction cervical ripening at home will be randomized to receive an outpatient trans-cervical ripening balloon (17 F non-latex Foley catheter) or hygroscopic cervical dilator (Dilapan-S). Patients present to the hospital for their scheduled induction of labor approximately 12 hours later.

We hypothesize that the trans-cervical balloon and hygroscopic dilators will show equivalent efficacy in cervical ripening, but that pain scores and patient satisfaction will be better with the hygroscopic dilators.
