Brief Summary

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

The vagus nerve innervates both the uterus and the cervix. It is thought that a successful and positive birth experience can be achieved by stimulating the vagus nerve at the desired level. Making instinctive sounds such as singing, humming, and various exercises are methods that stimulate the vagus nerve. In this project, an application protocol based on polyvagal theory and including breathing, relaxation and voice exercises was prepared. Video-supported application material will be developed in line with the prepared protocol. The video-assisted vagus nerve stimulation intervention is called Vagal Active Tone (VAT). VAT is a new method in the literature and for which we have limited information about labor. This project aimed to determine the effect of vagus nerve stimulation based on Polyvagal theory on labor pain, anxiety, oxytocin, cortisol levels, duration and perception of birth. This study was planned as a randomized controlled experimental study. The number of samples was calculated using the G\*power 3.1.9.6 program. After the power analysis, it is aimed to reach a total of 50 people, 25 in the intervention group and 25 in the control group. Data will be collected with Personal Information Form, Labor Monitoring Form, Hormone Levels Monitoring Form, Visual Analogue Scale, State Anxiety Scale, Facial Anxiety Scale and Mother's Birth Perception Scale.

It is aimed to produce new and original evidence-based information with the use of VAT intervention based on polyvagal theory. It is thought that this intervention, which can be easily accessed and applied by pregnant women whenever they want, will contribute positively to labor pain, anxiety, oxytocin and cortisol levels, and the duration and perception of birth.

PARALLEL

This project aimed to determine the effect of vagus nerve stimulation based on Polyvagal theory on labor pain, anxiety, oxytocin, cortisol levels, duration and perception of birth.

In this regard, the planned targets are;

* It is to determine the effect of vagus nerve stimulation on labor pain in pregnant women, based on Polyvagal theory.
* It is to determine the effect of vagus nerve stimulation on the anxiety level of pregnant women, based on the Polyvagal theory.
* It is to determine the effect of vagus nerve stimulation on the oxytocin level of pregnant women, based on the Polyvagal theory.
* It is to determine the effect of vagus nerve stimulation on cortisol levels of pregnant women, based on Polyvagal theory.
* It is to determine the effect of vagus nerve stimulation on the duration of birth of pregnant women, based on the Polyvagal theory.
* It is to determine the effect of vagus nerve stimulation on the birth perception of pregnant women, based on Polyvagal theory.

Blinding Strategy

SINGLE

Participants
In the study, hormone value analyses, statistics and reporting will be blinded. Before the pre-tests are collected in the collection of data, the responsible researcher will contact the statistician who performed the randomization and reach the randomization list. After learning the group information, the responsible researcher will start the application. The participant will be monitored under the supervision of the responsible researcher until they go to the postpartum care unit. A new participant will be included in the study after the participant is sent to the postpartum care clinic. Therefore, the intervention and control groups will be prevented from seeing each other.

For hormone analyses, the hormone tubes will be coded as "A" and "B" groups by the responsible researcher. Hormone value analyses will be performed by an expert laboratory technician who is not aware of the groups independent of the study.
