Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This project will include 110 women recruited from the obstetrical service at Prentice Women's Hospital. Women will be included if they are at least 37 weeks gestation, have a singleton pregnancy, have intact membranes and are undergoing an induction of labor using a Foley catheter. Following removal of Foley catheter, women will be assessed for safety of amniotomy and if appropriate, randomized to either early amniotomy or delayed amniotomy.
Women will be randomized with equal probability to the intervention group using block randomization stratified by use of Foley catheter alone or Foley catheter-misoprostol use.
Women in the early amniotomy group will undergo amniotomy within 1 hour of Foley catheter removal. Women in the delayed amniotomy group will undergo amniotomy at least 4 hours following Foley removal. The remainder of labor management will be at the discretion of each woman's obstetric provider.
Prior to discharge from the hospital, baseline demographic and clinical data will be obtained via chart review

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Early Amniotomy
Patients undergoing induction of labor with foley catheter, with or without concurrent use of misoprostol, will undergo amniotomy within 1 hour of Foley catheter removal.
Amniotomy
Artificially rupturing membranes
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.
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.
Delayed Amniotomy
Patients undergoing induction of labor with foley catheter, with or without concurrent use of misoprostol, will undergo amniotomy no sooner than 4 hours following removal of Foley catheter.
