Objective: Comparison effect of early versus late amniotomy on the duration time of first and second stage of labor, the cesarean section rate and analgesic use during labor.
Study Design: Randomized control trial study.
Setting: Labor unit, Department of Obstetrics and Gynecology, Phramongkutklao Hospital.
Subjects: 120 term singletons, nulliparous with cephalic presentation pregnant women who had spontaneous labor and came to labor room from June 1st, 2013 to October 31th, 2013.
Material And Method: After signed the consent form, the selected pregnant women were divided into two groups by random number table. The early amniotomy which performed when patients entered the active phase of labor (cervical dilatation 3-5 cm., n=60), and the late amniotomy which membrane was left intact and amniotomy was reserved for specific indications (n=60). The outcome of labor was recorded by the attending physicians. Main outcome measures: Compare the duration of labor between two groups.
Results: The time of first stage of labor was not different between early and late amniotomy groups (560.0 vs. 637.5 min; p<1.0; time difference 77.5 minutes). There was statistically significant difference between women in the early amniotomy and control groups in cesarean section rate (43.3% vs. 20%; p = 0.006).
Conclusion: The amniotomy should not be introduced routinely as the standard labor management, because it was not proven to shorten the course of labor. The authors recommend that the women be informed about the results of the amniotomy, then the decisions were made between the women and their caregivers.

Background: The approach to induction of labour differs internationally, with timing of amniotomy being controversial. Some institutions favour performing artificial rupture of membranes prior to commencement of oxytocin infusion, with the belief that the labour will progress more efficiently. In other institutions, the approach recommended is for oxytocin infusion with intact amniotic membranes until the person has reached the active phase of labour, citing risk of infection with early amniotomy.

Objective: To assess the maternal and fetal benefits of delaying oxytocin perfusion by 24 h following labor induction by amniotomy after 41 weeks of gestation (WG).
Methods: We performed a retrospective review including all women with a vertex presentation fetus who had an indication for labor induction by amniotomy with or without oxytocin after 41 WG between 2015 and 2022. Patients who underwent an IOL by amniotomy followed by oxytocin perfusion within 0 to 4 hours (early oxytocin group: EO group) were compared with patients who underwent an IOL by amniotomy alone or followed by an oxytocin perfusion after an expectant period for up to 24 hours in the absence of a spontaneous onset of labor (delayed oxytocin group: DO group).

Background: Mechanical labour induction with a transcervical balloon is as effective as pharmacological methods, with fewer adverse effects. Its use has been limited to labour induction with an unfavourable cervix able to retain the balloon. We have developed an innovative approach using 2-3 balloons side-by-side to extend the benefits of mechanical labour induction/augmentation with a favourable cervix without having to resort to amniotomy or uterotonics.

Objective: To assess the effect of early amniotomy on labor duration, maternal and neonatal outcomes during induction of labor (IOL).
Methods: This was a randomized controlled trial, conducted over a period of eight months at a monocentric site. Singleton pregnancies in nulliparous and parous patients with cephalic presentation and Bishop score ≥ 6 were enrolled in the study.

Background: Induction of labor in women with a previous cesarean section (CS) is associated with increased rates of uterine rupture and failed attempt for vaginal delivery. Prostaglandins use is contraindicated in this population, limiting available options for cervical ripening.
Objective: To evaluate the efficacy and safety of artificial rupture of membranes (AROM) as a mode of Induction of labor (IOL) in women with a previous cesarean section.
