Title: Cervical Foley Plus Vaginal Misoprostol Versus Vaginal Misoprostol for Cervical Ripening and Labor Induction: A Randomized Trial
Brief Summary: The purpose of this study is to compare the efficacy of the combination of the supracervical foley bulb and vaginal misoprostol to vaginal misoprostol alone for labor induction. We hypothesize that use of the foley bulb plus vaginal misoprostol will result in shorter induction to delivery time.


Options:
A: Inclusion Criteria:

1. Spontaneous rupture of membranes (ROM) ≥1 hour prior to starting induction; ROM defined as clinical history with the presence of 2 of the following 4: pooling, ferning, nitrazine, oligohydramnios. In the absence of clinical history, oligohydramnios AND pooling must be present for ROM to be diagnosed. Oligohydramnios is defined as a total amniotic fluid index of \<5cm or a maximum vertical pocket \<2cm.
2. Unfavorable cervix, defined as sterile digital exam ≤ 2cm dilated / 80% effaced
3. Gestational age ≥ 34 weeks by best obstetric estimate
4. Clinical management decision is vaginal delivery
5. Singleton gestation
6. Cephalic presentation
7. Willing to participate and able to understand and sign the informed consent document before randomization
8. Women of reproductive age

Exclusion Criteria:

1. Multiple gestations
2. Lethal fetal anomalies, e.g., anencephaly, trisomy 13, trisomy 18
3. Latex allergy
4. Greater than 1 prior cesarean delivery
5. Active labor - defined as contractions more frequent than every 5 minutes (or ≥ 12 contractions in 1 hour) associated with ≥ 1 cm cervical change. In the absence of ≥ 1 cm cervical change after 2 hours, patients with contractions can be included in the study.
6. Suspicion of chorioamnionitis
7. Any contraindications to vaginal delivery, including malpresentation, active herpes, complete placenta previa, greater than two prior cesarean deliveries, etc.
8. HIV positive status or AIDS
9. Intrauterine fetal demise
10. Suspected placental abruption, significant hemorrhage
11. Nonreassuring fetal heart rate (FHR) pattern
12. Participation in a competing trial
B: Inclusion Criteria:

* Full term singleton pregnancy with vertex presentation and with an indication for labour induction.
* Absence of active labour
* Bishop score ≤ 6.
* Normal CTG registration

Exclusion Criteria:

* Previous cesarean section
* signs of infection
* immediate need for delivery
* any contraindication for vaginal delivery
C: Inclusion Criteria:

* Age greater than 18 years
* Pregnant, singleton gestation, vertex presentation
* Admitted for induction of labor between gestational ages 24 - 42 weeks
* Bishop score \<6

Exclusion Criteria:

* Multiple gestation
* Non-vertex presentation
* Latex allergy or latex-free Foley catheter to be placed
* Fetal death
* Anomalous fetus
* Placenta/vasa previa
* Placental abruption (known or suspected)
* Intrapartum bleeding
* Non-reassuring fetal tracing with following criteria: category III tracing, OR minimal variability AND decelerations of any kind, OR late decelerations occurring \>50% of contractions
* 2 or more previous cesarean section, myomectomy, or classical cesarean
* Need to use ripening agents prior to Foley placement
* Spontaneous labor
* Active genital herpes
* Inability to consent
* Any contraindication to a vaginal delivery
D: Inclusion Criteria:

* singleton pregnancy
* vertex presentation
* unfavorable cervix(Bishop's score less than or equal to 6)
* greater than 24 weeks gestation

Exclusion Criteria:

* fetal malpresentation
* multifetal gestation
* spontaneous labor
* more than 5 uterine contractions in 10 minutes
* contraindication to prostaglandins
* non-reassuring fetal heart rate tracing
