Title: A Randomized Controlled Trial of Transcervical Foley Balloon Compared to Controlled Release Prostaglandin (Cervidil) for Labor Induction and Cervical Ripening in Term and Near Term Women
Brief Summary: OBJECTIVE: To assess the efficacy of transcervical Foley catheter compared to controlled release prostaglandin (Cervidil™) for cervical ripening in term and near term women presenting for labor induction.

HYPOTHESIS: In term and near term women presenting for labor induction, transcervical Foley catheter will decrease the mean time from induction to delivery by six hours compared to controlled release prostaglandin (Cervidil™).


Options:
A: Inclusion Criteria:

* singleton gestation
* presenting for induction as determined by their primary obstetrical provider
* with fetuses in cephalic presentation
* gestational age greater than 23 weeks

Exclusion Criteria:

* any condition precluding vaginal delivery
* estimated fetal weight \>4500 grams
* a previous attempt at ripening or induction during the pregnancy
* clinically significant cervical or vaginal infection
* chorioamnionitis
* HIV
* hepatitis B or C
* unexplained vaginal bleeding
* low-lying placenta
* abnormal cervical anatomy or cervical cerclage
* latex allergy
B: Inclusion Criteria:

1. Cervix \< 3 cm dilated. If 2cm dilated, must be \< 80% effaced.
2. Gestational age ≥ 36 weeks by best obstetric estimate, and clinical management decision is delivery.
3. Singleton gestation
4. Cephalic presentation

Exclusion Criteria:

1. Regular uterine contractions (more frequent than every 5 minutes)
2. PROM
3. Prior transverse uterine incision or any obstetric contraindication to labor
4. Fever (defined as a temperature of 38°C or higher)
5. Lethal fetal anomalies (Labor induction is being performed, but there is no plan for fetal heart rate monitoring or cesarean delivery for fetal indications.)
6. Fetal death
7. Placenta previa
8. Suspected placental abruption or undiagnosed bleeding characterized as more than "spotting"
9. Non-reassuring fetal heart rate pattern
10. HIV
C: 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
* intrauterine growth restriction
* anomalous fetus
* fetal demise
* previous cesarean delivery or other significant uterine surgery
D: Inclusion Criteria:

* Patients 15 years of age or older.
* Diagnosed to be pregnant with an indication for induction of labor.
* Having a Bishop score of 4 points or less.
* Diagnosed as having a singleton pregnancy in a vertex presentation, with intact membranes, and no significant regular uterine contraction at gestational age of \>28 weeks.
* Willingness to comply with the protocol for the duration of the study.
* Have signed an informed consent.

Exclusion Criteria:

* Any contraindication for a vaginal delivery (i.e. placenta previa, non vertex presentation).
* Ruptured membranes.
* Previous cesarean section or any uterine scar.
* Documented labor.
* Suspected fetal distress necessitating immediate intervention.
* Proven malignancy of the cervix.
* Active inflammatory or purulent condition of the lower genital tract.
