NCT03039036 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 69

No results posted yet for this study

Summary

Amniotomy (breaking the bag of water) is commonly used in the induction of labor. However, the timing is highly variable. The purpose of this study is to determine if first time mothers undergoing induction of labor with a Foley catheter experience a decrease in their labor time when undergoing early amniotomy (breaking the bag of water within 1 hour of Foley catheter removal) than when undergoing delayed amniotomy (breaking the bag of water at least 4 hours after Foley catheter removal). Other aims include the relationship between timing of amniotomy and cesarean section, postpartum hemorrhage, intrauterine infection, neonatal Apgar score \<7 at 5 minutes, neonatal need for intensive care.

The investigators hypothesize that induction of labor with Foley catheters followed by early amniotomy will result in a decreased duration of labor compared to those who undergo delayed amniotomy.

  • Labor Induction

PROCEDURE

Amniotomy

Artificially rupturing membranes

DEVICE

Foley Catheter

Foley catheter device is commonly used for cervical ripening during labor induction. It is used independently or in combination with pharmacologic augmentation. It is inserted in the cervix and the balloon is then inflated with 60 cc of saline. It is removed when either 1. it falls out under gentile traction during labor checks or 2. it is de-inflated at 12 hours after placement. If at the time of de-inflation at 12 hours, the desired affect has not been achieved, the provider may choose to place another foley balloon or use an alternative method of induction (misoprostol). This is an eligibility criteria and only patients who are undergoing induction with a Foley Catheter will be approached for enrollment.

DRUG

Misoprostol

Misoprostol is a medication that is commonly used for cervical ripening during labor induction. It is commonly used independently or in combination with mechanical methods, such as a foley catheter. The commonly used dose during term labor induction is 25 mcg. Use of this medication will be decided by the provider.
