Measuring Stress Reduction in Patients Receiving Multimedia Entertainment During Vascular Surgery Under Regional...

This study explores the treatment of internal carotid artery stenosis in patients with a high risk for cardiovascular events. The use of regional anesthesia permits ongoing neurological monitoring and enhances patient safety during the procedure. However, the operation can be stressful and lengthy, highlighting the need for strategies to alleviate patient discomfort. This study evaluates audiovisual distractions such as video goggles to potentially improve patient experiences during carotid surgeries, a topic that has not yet been comprehensively researched.

We aimed to (1) determine whether there is a benefit for patients regarding stress reduction when using video goggles during vascular surgery of the carotid artery and (2) determine whether any parameters can effectively measure such a potential benefit.

This prospective, randomized study at the University Hospital Augsburg is evaluating the use of HappyMed video goggles by patients undergoing carotid endarterectomy under regional anesthesia. Participants are randomized into either the intervention group, which receives the video goggles, or the control group, which does not. The surgical and anesthetic procedures remain consistent across both groups. Patients are eligible if they meet the surgical criteria, are able to lie supine, and are cooperative. Patients are excluded if they are receiving corticosteroids, have dementia, or have a language barrier. The study uses questionnaires and vital/laboratory parameters, including cortisol levels and heart rate, to assess stress and anxiety. To monitor potential motion sickness, the occurrence of nausea or vomiting is documented. Both patients and surgical staff will evaluate the experience postoperatively to determine the goggles' impact on patient experience and stress management during surgery.

The study has been approved by the local ethics committee and is registered at ClinicalTrials.gov. Patient inclusion started in September 2022 and should be completed within 3 to 4 years. This paper presents a study protocol that was finalized and approved by the local ethics committee in September 2022. At the time of this protocol's final submission for publication, approximately 90% of the recruitment had been completed. Following completion of recruitment and data acquisition, the results are intended to be published within one year.

This study aims to improve patient comfort and perioperative care during vascular surgery. Therefore, our study aims to investigate if the use of video goggles during surgery is feasible and if there are parameters that indicate a benefit for patients. This study is being conducted as a pilot trial to provide a foundation for future research aimed at improving patient comfort during carotid artery surgery under local anesthesia.
