Title: Foley Catheter Plus Vaginal Isosorbide Mononitrate Versus Vaginal Misoprostol for Induction of Labour:a Randomised Controlled Trial
Brief Summary: The use of foley catheter was tested many times and proved to be effective for induction of labour.


Options:
A: 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
B: Inclusion Criteria

* Nulliparous women aged 18 or above
* BMI ≥ 30 at the time of labor induction
* Singleton gestation
* Cephalic presentation (includes successful external cephalic version)
* Intact fetal membranes
* Unfavorable cervix (Bishop score of ≤ 6)
* Gestational age ≥ 32 weeks

Exclusion Criteria

* Patient not candidate for IOL with misoprostol as deemed by the treating physician
* Multiple gestation
* Major fetal anomalies
* Fetal demise
C: 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
D: Inclusion Criteria:

* Term or post term pregnancies.
* Live,singleton fetus.
* Cephalic presentation.
* Intact membrane.
* Bishop score \< 6.
* Not in labour.
* Medically indicated for labour induction.
* Primigravida or parity of 3 or less.

Exclusion Criteria:

* Previous caesarean delivery.
* Malpresentation.
* Placenta previa.
* Sever intrauterine growth restriction.
* Multiple pregnancy.
* Polyhydramnios.
* Oligohydramnios.
* Bishop score 7 or more.
