The Effect of Virtual Reality Headset on Anxiety, Sedation Need and Patient Satisfaction in Oncological Patients Scheduled for Port Catheter Implantation

The patients will be randomly divided into 2 groups and one group will be shown relaxing videos (nature scenes) by wearing a VR headset in addition to the routine anesthesia procedure, while the control group will undergo the routine anesthesia procedure.

All patients are taken to the operating room, patients will be informed about the study and VR headsets, informed consent forms will be obtained, and preoperative anxiety levels will be evaluated with the STAI (state-transit anxiety inventory) questionnaire. Patients will be monitored in accordance with American Society of Anesthesiologist (ASA) standards within the routine anesthesia practices and vital signs (ECG: Electrocardiogram, Non-invasive SAP: Systolic arterial pressure, DAP: Diastolic arterial pressure, MAP: mean arterial pressure, HR: heart rate, SpO2: peripheral oxygen saturation) will be monitored and an intravenous cannula will be placed. In the VR group, the patient will wear the VR headset right before the surgical procedure starts and will be removed after the last surgical suture is performed. If the patient initially consents but wishes to remove the VR headset during the procedure or if the anesthesiologist considers it necessary, the headsets can be removed, and these patients will be recorded. An anesthesiologist and a study member will be present in the operating room to adjust VR headsets and help with technical issues. The anesthesiologist will apply routine anesthesia protocols to both groups, administer any additional medications deemed necessary, and any additional medications will be recorded. Each patient will receive midazolam 0.05 mg/kg IV and fentanyl 1 mcg/kg IV immediately after intravenous cannula placement as part of the routine sedation protocol of anesthesia. The sedation level of the patients will be targeted at 2-3 levels according to the Ramsey Sedation Scale and 1-2.5 mg/kg/hr IV propofol infusion will be given. The surgical team will administer local anesthesia. The onset of anesthesia will be recorded when midazolam is administered, the completion will be recorded when the patient awakens, and the duration of anesthesia will be recorded as the time between these two events. The beginning of surgery, the moment the surgeon performs the local anesthesia, the end of the surgery, the end of the last suture and the duration of the surgery will be recorded as the time between these two events. The postoperative anxiety level will be assessed with the STAI (State-Trait Anxiety Inventory) questionnaire 1 hour after the end of surgery (T2) in the post-anesthesia care unit (PACU). In this study, no additional monitoring and drug administration will be performed, except for the procedures included in the routine sedation protocol of anesthesia.

Primary data are the need for additional anesthetics (total intraoperative propofol dose in mg, additional opiod dose in mcg) and anxiety levels. Secondary data are hemodynamic data (MAP, HR, SpO2 will be recorded every 10 minutes), patient satisfaction, time to put on and adjust VR headsets, number of patients who refuse VR headsets, number of patients who remove VR headsets before the procedure ends. Demographic data (age, gender, weight, height, body mass index-BMI), ASA and comorbidities, duration of surgery and anesthesia will also be recorded.
