In adults, the prevalence of preoperative anxiety related to surgery or anesthesia ranges from 60 to 80%, and context plays an important role. Patients with significant preoperative anxiety experience reduced sleep quality. In addition, high preoperative anxiety is linked to more severe postoperative pain and an increased need for painkillers. In addition, it is a source of dysfunction in care. Currently, there are no recommendations regarding the prevention of preoperative anxiety. New approaches have emerged that show some benefit: music, binaural auditory stimulation and hypnosis. In the UAC J0 unit of the Amiens-Picardie University Hospital, the caregivers offer the PSiO glasses, a tool combining three techniques: light therapy, relaxation and chromotherapy. This system has obtained CE and FCC markings and seems to be more or less effective on patients admitted to the CH . A pilot study evaluating the effects of virtual reality hypnosis on patients' preoperative anxiety has shown that this technology represents a non-invasive way to reduce preoperative stress levels without side effects and without the need for additional medical or paramedical staff. This study aims to improve the patient's well-being before their operation. Depending on the randomization, he will benefit from a relaxation session with the Psio glasses or a virtual reality hypnosis session with the Hypno VR headset. Follow-up of patients will be carried out on the basis of variation in an anxiety scale, physiological criteria, the amount of anesthetic products used, the time spent in the recovery room, and the evaluation of pain.
