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.
Patient treated at the UAC D0
Orthopedic patient (arthroplasty mainly)
Anesthesic procedure with general anesthesia
Patient >18 years old without cognitive impairment in the investigator's judgment
Patient with deafness that does not allow him to perceive and understand sounds
Patient with a visual impairment who does not allow him to watch and understand a video
Patient who does not master the French language (spoken, written and read)
Patient with a history of epilepsy
Parallel
HypnoVR
DeviceThe patient will benefit from a 20-minute virtual reality hypnosis session in the universe of his choice. The experience consists of hypnotic speech, adapted to the study population, inducing a state of relaxation (guided breathing sequences, cardiac coherence exercises, positive suggestions), an evolving 3D virtual journey and a musical atmosphere.
PSIO
Devicethe patient will be given a 20-minute relaxation session with the PSiO® glasses. The experience consists of a visual stage with shimmering colors and music.
no relaxation tool
DeviceGroup without relaxation tool: the patient will wait 20-minute, without benefit of sendorial tools.
Variation in the score on the APAIS anxiety scale
Variation in the score on the APAIS scale, 6-item scale rated from 1 to 5 The anxiety score sums items 1, 2, 4 and 5 (\>11 = anxious subjects) The information desire score sums items 3 and 6 (2 to 4 = refusal of information, 5 to 7 = average desire for information, \>7 = eager desire for information)
