Length of Cook Catheter Placement and Induction of Labor

May 29, 2022 updated by: Sarah E Little, Brigham and Women's Hospital

Length of Cook Catheter Placement and Induction of Labor: a Randomized Controlled Trial

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 50 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Description

Inclusion Criteria: Women undergoing cervical ripening for labor induction at term (37-41 6/7 weeks) with a singleton gestation in cephalic presentation. Women will need to have a bishop score <6 or cervical dilation <2cm with intact membranes to be included.

Exclusion Criteria:

  • Non English speaking
  • Contraindications to vaginal delivery
  • Prior cesarean section

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: 6 hour foley
The participant will have a cook catheter inserted digitally or by direct visualization with a speculum with the uterine component of the balloon inflated to maximum 60mL. The catheter will be taped to the inner thigh with gentle traction. Participants will be started on hospital-based oxytocin protocol. The cook catheter will then be removed at 6 hours, determined by randomization. At that point health care providers will manage active labor.
Device: Foley catheter length
see arm description
No Intervention: 12 hour foley
The participant will have a cook catheter inserted digitally or by direct visualization with a speculum with the uterine component of the balloon inflated to maximum 60mL. The catheter will be taped to the inner thigh with gentle traction. Participants will be started on hospital-based oxytocin protocol. The cook catheter will then be removed at 12 hours, determined by randomization. At that point health care providers will manage active labor.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
