Length of Cook Catheter Placement and Induction of Labor

Not Applicable
Completed
Conditions
Induction of Labor
Interventions
Device: Foley catheter length
Registration Number
NCT04233008
Lead Sponsor
Brigham and Women's Hospital
Brief Summary

The goal of this study is to compare cook catheter placement for 6 vs. 12 hours to see if there is faster time to delivery for people admitted to labor and delivery undergoing induction of labor.

Detailed Description

Upon presentation to labor and delivery the participant will have a cook catheter inserted digitally or by direct visualization with a speculum. The uterine component of the balloon will be inflated to maximum 60mL. The catheter will be taped to the inner thigh with gentle traction. In both groups participants will be started on hospital-based oxytocin protocol. This protocol beings with 2 milliunits/min of oxytocin, increasing by 2 milliunits every 15 minutes until regular uterine contractions occur. The maximum dose of oxytocin is considered to be 30 milliunits. The cook catheter will then be removed at 6 vs. 12 hours based on randomization. At that point health care providers will manage active labor. Health care providers many perform amniotomy at any point during the induction process with recommendation for amniotomy with cervix more than 4cm dilated. Labor interventions are at the discretion of the healthcare provider. The participants will have continuous fetal monitoring throughout their induction, labor and delivery. Need for operative delivery or cesarean section will be at the discretion of the health provider.
