Title: A Randomised Comparison Between Intravaginal Dinoprostone Intravaginal Misoprostol and Transcervical Balloon Catheter for Labour Induction
Brief Summary: This is a randomised study aimed at comparing the currently most frequently used prostaglandin dinoprostone to two other methods, the cheaper and perhaps more effective prostaglandin misoprostol and a transcervical catheter. 592 women were recruited and randomised to one of the three methods. The main outcome measures were time to delivery, rate of instrumental deliveries and maternal neonatal outcome. Our hypothesis was that misoprostol would be superior to the other methods.

The main finding of our trial was that the catheter showed the shortest induction to delivery interval. There were no differences between the two other prostaglandins. No differences in maternal and neonatal outcome was found


Options:

* With a singleton cephalic pregnancy between ≥41+0 weeks and ≤ 42+0 weeks of gestation
* Gestational age estimated from the first trimester ultrasound (realized between 11 and 13+6 weeks of gestation)
* With a decision of induction of labour
* Written informed consent obtained from subject
* Subject covered by or having the rights to the French Social Security system

Exclusion Criteria:

* Bishop score ≥ 6 (favourable cervix)
* Non cephalic presentation (breech, transverse)
* Severe preeclampsia defined as the presence of preeclampsia with at least one of the following items :

  * Severe maternal hypertension (systolic blood pressure ≥ 160 mm Hg and/or diastolic blood pressure ≥ 110 mm Hg)
  * Renal failure with oliguria (\< 500 ml/24h) or creatinine \> 135μmol/L, or proteinuria \> 5 g/day
  * Pulmonary oedema, epigastric pain or HELLP syndrom (hemolysis, elevated liver enzyme, low platelets)
  * Eclampsia or neurologic persisting symptoms (visual disturbances, headache, increased reflexes)
  * Thrombopenia \< 100 G/L
* Prior caesarean section or uterine scar
* Placenta praevia
* Suspected genital herpes infection
* Known VIH seropositivity (confirmed by blood serology)
* Premature rupture of membranes (PROM - continual leaking of amniotic fluid or positive test in favour of PROM)
* Foetus with suspected severe congenital abnormalities
* Pathological fetal heart rate
* Contra-indications to Propess®
* Contra-indications for using Cook® Cervical Ripening Balloon
* Women under guardianship or trusteeship
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:

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
D: 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
