About

There are more and more pregnant women who are obese. It is very difficult for obese women to get into labor. That is why when women are obese, half are likely to need a Cesarean delivery(C-section). Unfortunately, C-sections are more dangerous for obese women. There may be a combination of issues that cause obese women to need C-sections. We believe one of those reasons is that the womb of obese women respond differently to medications and devices compared to non-obese women. There are commonly two ways to help women get into labor. One way is a medication called misoprostol. The second way is a device called Foley balloon. In most studies, both ways are equally effective in helping women get into labor. However, these studies included everyone, and didn't focus on obese women.

So far there are no studies in this area that focus only on obese women. Therefore we need to design this study to focus just on obese women and what is the best way to help them get into labor and avoid a C-section.

0 participants in 2 patient groups

misoprostol

Active Comparator group

Description:

Induction using misoprostol: Insert misoprostol 25 micrograms in the posterior fornix of the vagina digitally Repeat cervical exam every 4 hours

Treatment:

Drug: Misoprostol

Misoprostol and foley bulb

Experimental group

Description:

Induction using Foley balloon combined with misoprostol: A 26 French intracervical Foley balloon will be inserted above the internal os at the start of induction, inflated using 80cc of sterile water. If a Foley balloon is not able to be inserted at the time of starting induction of labor, misoprostol 25microgram can be inserted in the posterior fornix of the vagina and the misoprostol protocol followed.

Treatment:

Drug: Misoprostol
