Yksityiskohtainen kuvaus
Patients will be randomly assigned (like rolling the dice) to one of 2 groups.
- Group 1 will follow the standard induction of labor protocol at KUMC. In other words, their induction process will not look any different than if they were not a participant in this study. Their induction process may include, but is not limited to, medications and/or devices to make the body more ready to deliver the baby, medications to increase the uterus muscle contractions, medications to decrease the pain associated with labor, etc. Group 1 will not use nipple stimulation at all as part of their labor.
- Group 2 will follow the standard induction of labor protocol with the addition of nipple stimulation using the Symphony PLUS® breast pump for a 2-hour time period. At the time in their labor when the medical team would normally deem them appropriate to initiate synthetic oxytocin (Pitocin), nipple stimulation will be started instead. The breast pump will be placed over one nipple at a time and put on its default vacuum settings. Every 15 minutes, the patient will switch to stimulating the alternate nipple with no breaks of time in between. Depending on how fast the contractions are, the research team may increase or decrease the strength of the breast pump. This will continue for 2 hours, after which they will stop doing nipple stimulation. They will then resume normal induction of labor care as deemed appropriate by the nurses and doctors.
Patients will have a 1 in 2 chance (50%) of being randomized to either Group 1 or Group 2. Group assignments will be chosen by a randomization tool. Patients and the study team will be aware of which treatment they are under.
After delivering the baby, both groups will take a survey about their induction experience while they are in the hospital. After the survey is collected, patients have completed participation in this study. Patients will continue to receive standard care with their primary physician team.
The investigators will take information about the patients and their medical care from the electronic medical record for research purposes. The investigators will be analyzing things such as how long it took from the beginning of induction to the delivery of the baby, if there were any unexpected events, how much synthetic oxytocin was used, and other information about the induction and the health of the baby. The investigators will also analyze the results of the surveys completed.

Active Comparator: Control
Patients randomized to the control group will follow standard induction of labor protocol, which may include, but is not limited to, misoprostol, Foley catheter, and synthetic oxytocin (Pitocin).
In other words, their induction will be the same as if they were not enrolled in the study.

Kokeellinen: Nipple Stimulation
Patients randomized to the experimental group will undergo standard IOL protocol with the addition of nipple stimulation. At the time when the labor and delivery team deems a patient suitable for Pitocin initiation, patients will begin using a Symphony PLUS® breast pump for nipple stimulation. The breast pump will be turned on and placed on one breast (around the nipple) for 15 minutes, alternating breasts every 15 minutes. The default pump vacuum settings will be utilized. Contraction pattern and pump settings will be assessed every 30 minutes and adjusted if needed to maintain uterine contractions at a rate between 3 and 5 contractions per 10 minutes averaged over 30 minutes. Patients will perform nipple stimulation for no greater and no less than 2 hours. They will then resume normal care. |
Symphony PLUS® breast pump.
What distinguishes this induction of labor nipple stimulation study is how we will be applying the nipple stimulation.
Many other studies exist, but they apply the stimulation in an uneven or inconsistent manner.
They often do not specify how they interpret active and latent labor.
Our study will be using nipple stimulation only for 2 hours per experimental participant so that we can better quantify the effect that nipple stimulation has on the labor process.

Surveys will be administered to patients in their postpartum period, labor and delivery nurses after the patient portion of the study has been completed, and OBGYN providers Pre and Post patient portion of the study.
These surveys will ask about familiarity with nipple stimulation, how they liked using it, and if they would use it again for induction of labor.
