Background Advancements in virtual reality (VR) technology have resulted in its expansion into healthcare. Preliminary studies have found VR to be effective as an adjunct to anesthesia to reduce pain and anxiety for patients during upper gastrointestinal endoscopies, dental procedures and joint arthroplasties. Current standard care practice for upper extremity surgery includes a combination of regional anesthesia and intraoperative propofol sedation. Commonly, patients receive deep propofol sedation during these cases, leading to potentially avoidable risks of over-sedation, hypotension, upper airway obstruction, and apnea. The objective of this study is to evaluate the effectiveness of VR technology to promote relaxation for patients undergoing upper extremity surgery, thereby reducing intraoperative anesthetic requirements and improving the perioperative patient experience.Methods In this single-center randomized controlled trial, 40 adult patients undergoing upper extremity orthopedic surgery will be randomly allocated to either intraoperative VR immersion or usual care. VR immersion is designed to provide patients a relaxing virtual environment to alleviate intraoperative anxiety. All patients receive a peripheral nerve block prior to surgery. Patients in the intervention group will select videos or immersive environments that will be played in the VR headset during surgery. An anesthesia provider will perform their usual clinical responsibilities intraoperatively and can administer anesthetic medications if/when clinically necessary. Patients in the control arm will undergo perioperative anesthesia according to standard care practice. The primary outcome is the difference in intraoperative propofol dose between groups. Secondary outcomes include postoperative analgesia requirements and pain scores, length of stay in the post-anesthesia care unit, overall patient satisfaction and postoperative functional outcomes.Discussion It is unknown whether the use of VR during upper extremity surgery can reduce intraoperative anesthetic requirements, reduce perioperative complications, or improve the postoperative patient experience. A positive result of this clinical trial would add to the growing body of evidence that demonstrates the effectiveness of VR as an adjunct to anesthesia in reducing intraoperative pain and anxiety for multiple procedure types. This could lead to a change in practice, with the introduction of a non-pharmacologic intervention potentially reducing the burden of over-sedation while still providing a satisfactory perioperative experience.
