Effect of Intraoperative Virtual Reality on Anxiety and Vital Findings in Patients Total Knee Replacement Surgery

The Effect of Intraoperative Virtual Reality Application on the Level of Anxiety and Vital Findings in Patients Who Will Have Total Knee Replacement Surgery: A Randomized Controlled Study

Although total knee replacement surgery improves the quality of life of the patients, a significant reduction in knee pain and normalization of the knee joint, the awareness of the surrounding events is a major concern for the patients and negatively affects their vital signs, since most of the patients are awake during the surgery. When the literature is examined, there are no pharmacological methods to reduce anxiety.

When distraction techniques are used, patients' anxiety levels are significantly reduced, vital signs are normalized, patient satisfaction is increased and pain is relieved.

It has been emphasized that there is a successful method in reducing One of the distraction techniques is the application of virtual reality. This study will be carried out in a randomized controlled experimental design to determine the effect of virtual reality application during surgery on patients who will undergo total knee replacement surgery, on the anxiety level and vital signs of the patients.

The aim of this study is to determine the effect of virtual reality application on patients' anxiety level and vital signs during surgery for patients who will undergo total knee replacement surgery.

It will consist of patients over the age of 18 who will have total knee replacement surgery, which will be carried out in the Operating Room Unit. Patients meeting the sample selection criteria were randomized into experimental and control groups.

will be divided into two groups. Virtual reality glasses will be applied to the experimental group. In the collection of data; "Patient Information Form", "State Anxiety Inventory Scale" and "Vital Signs Follow-up Form" will be used.
