Relaxation Exercise With Virtual Reality Glasses and Episiotomy-induces Perineal Pain and Fear

This research is a single-blind, randomized controlled experimental study with pre-post and control groups. The population of the study consisted of pregnant women who applied to the Delivery Room in İzmir Bakırçay University Çiğli Training and Research Hospital Travay Birth Postpartum Service. The data pool could not be created because the sample was composed of women who applied for childbirth. In this randomized controlled trial, block randomization was applied. Because when simple randomization is applied, there may be a large difference between the numbers of subjects in the two groups when the study is completed. As the difference between the number of pregnant women in the virtual reality glasses and control groups grows, the reliability of the statistical analysis will decrease. Simple randomization is not recommended in cases where the sample size is less than 200. Although it was planned to take 38 experimental and 38 control group samples that met the inclusion criteria, the block randomization was carried out on 100 people, taking into account the exclusion criteria from the sample.

The randomization of the sample was made using the "random number generation program (Research Randomizer)". Intervention and control groups were formed by performing the randomization process by an impartial researcher who was not involved in the research. While it was known by the researchers in which group the pregnant women were, unilateral blindness was provided by not informing the pregnant women about the groups they were in. Since it is recommended in the literature that each step of randomized controlled trials should be performed according to the Consolidated Standards of Reporting Trials (CONSORT), this study was also conducted according to CONSORT. The type 1 error level of the study was determined as 5% (p=o.o5), the type II error level was 0.20 (80% power) and the effect size was 0.3 (moderate). Data were collected between December 2022 and May 2023. Data collection takes an average of 15 minutes.

Virtual Reality Glasses Group:

Pregnant women in the virtual reality glasses group who agreed to participate in the study and watch a relaxation video with virtual reality glasses were expected to answer the questions in the socio-demographic and obstetric information form during the latent phase of labor. Afterwards, they were asked about how many points of pain and fear they would experience on the VAS during the episiotomy incision and repair, on a scale of 0-10. After this form was answered, a relaxation video was watched with virtual reality glasses during the episiotomy incision and repair. After these procedures, as soon as the episiotomy incision and episiotomy repair were completed, virtual reality glasses were removed and the score of pain and fear they experienced was asked. They were asked to rate the pain and fear they experienced, giving a score between 0-10.

Control Group:

Pregnant women who agreed to participate in the study and who would be in the control group were expected to answer the questions in the socio-demographic and obstetric information form during the latent phase of labor. Afterwards, they were asked to score an estimated 0-10 score for pain and fear levels with VAS during episiotomy incision and repair. After this form was answered, no intervention was made during the episiotomy incision and repair, except routine practice. After these procedures, as soon as the episiotomy incision and episiotomy repair were completed, they were asked about the score of pain and fear they experienced. They were asked to rate the pain and fear they experienced, giving a score between 0-10.

Hypotheses:

1. H0-Relaxation exercise performed with virtual reality glasses does not affect the perineal pain score experienced while performing the episiotomy incision.

   H1- Relaxation exercise performed with virtual reality glasses reduces the perineal pain score experienced while performing the episiotomy incision.

2. H0-Relaxation exercise performed with virtual reality glasses does not affect the perineal pain score experienced during episiotomy suturing.

   H1- Relaxation exercise with virtual reality glasses reduces the perineal pain score experienced during episiotomy suturing.

3. H0-Relaxation exercise performed with virtual reality glasses does not affect the fear score experienced while performing the episiotomy incision.

   H1- Relaxation exercise performed with virtual reality glasses reduces the fear score experienced while applying the episiotomy incision.

4. H0- Relaxation exercise performed with virtual reality glasses does not affect the fear score experienced during episiotomy suturing.

H1- Relaxation exercise with virtual reality glasses reduces the fear score experienced during episiotomy suturing.

Data collection tool(s):

• Socio-demographic and Obstetric Information Form This form; age, education level, income level, marital status, body mass index, employment status, occupation, social security, place of residence, cohabitant, obstetric characteristics (pregnancy, birth, abortion, number of curettage), smoking and alcohol use, hospitalization In the application, there are questions about cervical dilatation and effacement level, previous delivery method, episiotomy application status. This form was applied to the women who will be included in the experimental and control groups during the latent phase of labor.
• Visual Analog Scale Pain Form The Visual Analog Scale is a scale developed by Price et al. in 1983 and is also used in the evaluation of episiotomy pain. VAS is 10 cm long. A minimum of 0 and a maximum of 10 points can be obtained from this scale. A score of zero indicates no pain, and a score of 10 indicates the pain felt at the highest level. The higher the score, the higher the level of pain.
• Visual Analog Scale Fear Form (VAS-FF) The visual analog scale is a valid and reliable measurement tool to measure other subjective emotions such as mood, in addition to pain. Fear of having an episiotomy is one of these mood changes. VAS is 10 cm long. A minimum of 0 and a maximum of 10 points can be obtained from this scale. She was asked to rate the score of fear experienced during episiotomy incision and repair between 0 and 10 points. A score of 0 indicates no fear, and a score of 10 indicates the highest level of fear. The higher the score, the higher the level of fear experienced.

Statistical method(s) to be used:

Data analysis will be done with SPSS 26 package program. In the evaluation of data; mean, standard deviation and percentage values will be calculated. In order to evaluate the homogeneity of the data according to the groups, the Skewness-Curtosis values will be examined and the tests to be used in the analysis will be decided. A probability value of p\<0.05 will be considered statistically significant.
