NCT06456164

Brief Summary

The goal of this research is to understand whether it is practical and safe to use an intracervical balloon catheter in addition to standard of care medications at the time of an induction of labor for an abortion or fetal death. The medical device used in this study is cleared by the Food and Drug Administration (FDA) and is used for induction of labor at term gestational ages (at or above 37 weeks of gestation). The study team will also collect data about patient-level experiences with the procedure, time in labor, and labor-related complications, such as higher-than-expected blood loss or infection.

Outcome Measures

Primary Outcomes (13)

  • Number of participants diagnosed with a cervical laceration

    During delivery hospitalization (within 72 hours after delivery)

  • Number of participants requiring adjunctive procedures in the setting of postpartum hemorrhage

    Dilation and curettage, insertion of intrauterine tamponade device (i.e., Bakri or Jada devices), uterine artery embolization, exploratory laparotomy, O'Leary and/or B-Lynch sutures, and/or other uterine-conserving surgical measures to control hemorrhage

    Up to 6 weeks post-delivery

  • Number of participants requiring hysterotomy or dilation and evacuation

    Need for hysterotomy or dilation and evacuation in setting of failed induction of labor

    During delivery hospitalization (within the first 72 hours after admission)

  • Number of participants diagnosed with a uterine rupture

    Up to 6 weeks post-delivery

  • Patient-reported acceptability of intervention

    Up to 6 weeks post-delivery

  • Patient-reported satisfaction

    During intrapartum period (up to 72 hours after delivery)

  • Total duration of labor, in hours

    During intrapartum period (up to 72 hours after delivery)

  • +2 more secondary outcomes

Study Arms (2)

Usual Care

NO INTERVENTION

Participants will receive mifepristone 200 mg by mouth 24 hours prior to induction of labor. Labor will be induced with use of vaginal misoprostol according to regimens endorsed by the American College of Obstetricians and Gynecologists and the Society of Family Planning.

Usual care with mechanical dilation

EXPERIMENTAL

Participants will receive mifepristone 200 mg by mouth 24 hours prior to induction of labor. Participants will have their labor induced concomitantly with misoprostol (according to the regimen described in the "Usual Care" arm) and placement of the Cook Cervical Ripening Balloon.

Device: Cook Cervical Ripening Balloon

Interventions

The Cook Cervical Ripening Balloon is a double-balloon catheter designed to mechanically ripen the cervix prior to labor induction when the cervix is unfavorable for induction.

Usual care with mechanical dilation
