Summary

For many years, total knee arthroplasty (TKA) has been a common and effective procedure to treat chronic refractory joint pain. Although efforts must be pursued, as general anesthesia remains the main tendency for TKA. Currently, the standard of care to manage procedural anxiety is pharmacological sedation; i.e. the intravenous administration of additional anesthetic agents such as propofol or midazolam. However, pharmacological sedation has considerable undesirable side effects. Hence, risks of intraprocedural adverse events including respiratory depression, hemodynamic perturbations, or paradoxical effects such as hostility, aggression, and psychomotor agitation, are increased. The goal of this prospective, single-center, randomized controlled clinical trial is to systematically evaluate the impact of implementing a protocol of virtual reality hypnosis in patients undergoing total knee arthroplasty under spinal anesthesia.

Interventions

DEVICE

VRH

The VR headset and headphones will be placed on patients after the spinal anesthesia, once the patient is positioned and the surgical drapes installed. Patients will then undergo a 120-minute Digital Sedation™ program (Aqua+© 120 Version 1.1 or subsequent version, Oncomfort SA, Waver, Belgium). They will experience an underwater experience while listening to hypnotic script designed to induce a change in state of consciousness, increasing parasympathetic system tone and relaxation response, and reducing the perception of painful stimuli. While the session is running, HCPs can see what is projected into the VRH headset on their Sedakit's X2 controller (i.e. the tablet connected to the glasses).

DRUG

Midazolam sedation

During the procedure, the patient in the control group receives pharmacological sedation, which is the standard of care currently practiced. Such sedation allows intraoperative anxiolysis, which is constantly required by patients in order to dissociate from their surroundings. Recall that total knee replacement surgery is extremely noisy, and the surrounding environment is itself an anxiety-provoking factor for the patient. Light to moderate, intraoperative sedation is carried out by intermittent boluses of midazolam 1 mg IV. Boluses are given every 5 minutes until a sedation level of -2 or -3 on the RASS (Richmond Agitation-Sedation Scale) scale is reached.
