The Effect of Information About the Operating Room Environment With Virtual Reality Glasses on the Anxiety Level

Summary

Virtual Reality (VR) applications, one of the commonly emphasized approaches in the medical field recently, is in place as an intervention method applicable in various fileds of medicine for distraction, experiencing being exposed to events creating stress and palliating anxiety through providing materials which may distract the patient's attention from a stressful condition. The study has been planned in order to evaluate the effect of the notification regarding the theatre environment through virtual reality to the patients, who are to go through abdominal surgical intervention, on the anxiety level and the vital signs during the surgical intervention.

Being a non-pharmacological clinical randomize controlled one, the study shall be conducted in Dr. Burhan Nalbantoğlu State Hospital of TRNC Ministry of Health surgical service and preoperative waiting area.

Sample number has been determined through power analysis using G\*Power 3.1.9.2 software. Taking (2017) "The effect of virtual reality in reducing preoperative anxiety in patients prior to arthroscopic knee surgery: A randomised controlled trial" study of Robertson and friends as the reference, the effect size, regarding the anxiety scores of experiment and control groups participants, has been determined as 0,63. Accordingly, sample size has been calculated as 71 people necessary for 95% (1-β=0,95) power at d=0,63 and α=0,05 levels. Taking into account there may be losses during the study, it has been planned to involve 80 people, so as to have 40 people per each group, in the study.

Since the patients, who are to be involved in the study, are not known; in order to assign same quantity of patients to each group prior to the study, randomization shall be done through using block randomization technique in GraphPad software so as to have 40 patients in the intervention group and 40 in the control group. The patients who receive standard clinical care prior to abdominal surgical intervention shall constitute the control group, the patients who receive information about operating room environment through VR goggles in addition to standard clinical care shall constitute the intervention group. The data shall be collected through "Individual characteristics Form", ''Patient Charts'', ''Surgical Anxiety Scale'', ''Galvanic Skin Sensor (GSS) Measurement Table''.

SPSS 26 Statistical analysis program shall be used for evaluating the study data. The acquired data shall be tested at 95% confidence interval, p\<0,05 level of significance. Number, percentage distributon and standard deviation for the definitive data analysis, chi square test for experiment and control groups' basic particulars similarity, Shapiro-Wilk for normality analysis of dependent variables, Student t test or Annova for the comparison of pre-test and final test scores of experiment control groups, the comparisons of variables giving normal distribution among the groups as per the normal distributon in the comparison of experiment control groups' pre-test and final test scores, Mann Whitney U test or Kruskal Wallis test for the variables of non-normal distribution shall be used.

Conditions

• Preoperative Anxiety

Interventions

OTHER

VR

The first interview with the patients in the intervention group will be held in the afternoon, the day before the surgery. After completing the forms and scale the video containing information about the operating room environment will be applied to the patients through SG glasses and headphones. Before the surgical intervention, patients admitted to the pre-operative waiting area from the clinic, the video containing information about the operating room environment will be watched by the patients through SG glasses and headphones.
