Breast stimulation vs low dose oxytocin for labor augmentation in women with a previous cesarean delivery, a randomized controlled trial

What Was Tested

This randomized controlled trial paper looks at Oxytocin.

In a cohort of patients with one previous CD, the researchers aimed to compare maternal and neonatal outcomes according to the method of labor augmentation; breast stimulation or intravenous oxytocin.

Why It Was Studied

Oxytocin and breast stimulation are methods used for labor augmentation in women with a previous cesarean delivery (CD).

The optimal method of labor augmentation for women with a prior CD has not been established.

Who Took Part

By PubMed's age tags, the people studied were adults, women only.

The participants had one previous CD and a cervical dilatation of 2 to 6 cm, had inadequate uterine contractions, defined as less than 3 per 10 minutes, and were candidates for labor augmentation.

Both augmentation treatments were continued for a maximum of 12 hours.

How the Study Was Run

In design terms this was a randomized study.

Because people in this Oxytocin study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

This randomized controlled trial (RCT) was conducted at a single, tertiary, university-affiliated hospital.

An intrauterine pressure catheter was inserted.

If active labor did not occur within 12 hours, the intervention was deemed a failure.

An intention-to-treat analysis was performed.

The co-primary outcomes were the time from augmentation to delivery, and uterine contraction intensity as measured by Montevideo units (MVU).

What Was Measured

Secondary outcomes included intervention failure, meconium-stained amniotic fluid, vaginal delivery after cesarean section, uterine rupture, infectious outcomes, postpartum hemorrhage, and maternal hospitalization length.

The authors tagged it with the keywords Montevideo, oxytocin augmentation, trial of birth after cesarean, uterine contractions and uterine rupture.
