What this Trial Is About
This research evaluates the use of virtual reality (VR) alongside spinal anaesthesia during total knee arthroplasty (TKA). The study aims to determine if VR can reduce the need for deeper sedation while maintaining patient satisfaction and potentially lowering side effects commonly linked to sedation such as nausea, confusion, and breathing difficulties. It also explores the feasibility and outcomes of VR use in this surgical setting. Participants will all receive spinal anaesthesia. They are randomly assigned to one of two groups: one group will use VR combined with light sedation, while the other group will receive standard care with deeper sedation but no VR. The study compares these approaches to assess if VR can help reduce sedation dosage and related side effects during TKA. During the study, patients will be monitored for sedation levels, recovery quality, and complications up to one week after surgery. Researchers will assess various outcomes including sedation amount, cognitive tests, mobilization time, pain management, anti-nausea medicine use, and hospital stay length. The primary outcome is to evaluate the feasibility of using VR during TKA with spinal anaesthesia, measured the day after surgery.
