Clinical Trial Summary

Combined misoprostol and Foley bulb catheter has been shown to be an effective induction method. However, optimal route of administration for misoprostol has not been established. Therefore, the purpose of this study is to compare the effectiveness and safety of combination buccal miso-foley to combination vaginal miso-foley for third trimester cervical ripening and induction of labor.

Description:

This randomized controlled trial of consenting women undergoing induction of labor with combined misoprostol and Foley catheter seeks to efficacy of vaginal versus buccal misoprostol route of administration. This project will include 216 women presenting at Christiana Care Health System. Women will be included if they are at least 37 weeks gestation, have a singleton pregnancy, have intact membranes and are undergoing an induction of labor using a Foley catheter combined with misoprostol. Following admission, women will be randomized into either vaginal or buccal misoprostol. Women will be randomized with equal probability to the intervention group using block randomization stratified by party. Patients will receive 25 micrograms of misoprostol along with the insertion of a16F Foley catheter. Misoprostol can be repeated up to five additional times for a maximum of 24 hours or a total of 6 doses if the patient is not contracting more than 3 times per 10 minutes. The remainder of labor management will be at the discretion of each woman's obstetric provider. Prior to discharge from the hospital, baseline demographic and clinical data will be obtained via chart review

Related Conditions & MeSH terms

• Induction of Labor

Intervention

Drug:
• Misoprostol
Women randomized to either vaginal or buccal misoprostol-cervical Foley group will have both misoprostol and a cervical Foley placed. Patients will receive 25 micrograms of vaginal or buccal misoprostol along with the insertion of a16F Foley catheter with stylet. The Foley balloon catheter will be filled with 30cc balloon inserted digitally or by direct visualization with a speculum. The Foley bulb will be placed just above the level of the internal os and inflated with 30cc of sterile water. vaginal or Buccal misoprostol can be repeated up to five additional times for a maximum of 24 hours or a total of 6 doses if the patient is not contracting more than 3 times per 10 minutes. If the patient is contracting more than 3 times per 10 minutes after 6 hours, oxytocin protocol is initiated.
