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

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.

About this study

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.

Treatment and study plan

Virtual reality

Behavioral

The Patient Information Form and the State Anxiety Scale will be administered to the patients just before the surgery. The researcher will measure the patient's respiratory, blood pressure, pulse and oxygen saturation values on the monitor just before the start of the operation and every 15 minutes after the operation, and the vital signs will be recorded in the follow-up form. Virtual reality glasses will be put on the patient immediately after anesthesia is given to the patient by the anesthesiologist. Glasses will be worn during the total knee replacement surgery. Total knee replacement surgery takes an average of 60 minutes. During the surgery, patients will be shown nature and landscape images with virtual reality glasses. Virtual reality glasses will be removed immediately after the operation and the State Anxiety Scale and vital signs follow-up form will be applied before the patient is sent to the service from the operating room.

Primary outcomes

  1. State Anxiety Scale

    Time frame: 10 minute

    State Anxiety Scale mean scores of the patients in the intervention and control groups will be compared before and after surgery. A minimum of 20 and a maximum of 80 points can be obtained from the scale. If the scale score approaches 80, it indicates high anxiety.

  2. Respiratory Rate

    Time frame: 15 minute

    Just before the start of the operation and every 15 minutes after the operation, the patient's respiratory rate values will be measured on the monitor and the respiratory rate will be recorded in the follow-up form.

  3. Blood Pressure (both systolic and diastolic blood pressure)

    Time frame: 15 minute

    Just before the start of the operation and every 15 minutes after the operation, the patient's blood pressure (both systolic and diastolic blood pressure) values will be measured on the monitor and the blood pressure (both systolic and diastolic blood pressure) will be recorded in the follow-up form.

  4. Pulse

    Time frame: 15 minute

    Just before the start of the operation and every 15 minutes after the operation, the patient's pulse values will be measured on the monitor and the pulse will be recorded in the follow-up form.

  5. Saturation Value

    Time frame: 15 minute

    Just before the start of the operation and every 15 minutes after the operation, the patient's saturation value will be measured on the monitor and the saturation will be recorded in the follow-up form.
