Effectiveness of Hypnosis Via Virtual Reality During Oocyte Retrieval

Transvaginal ultrasound-guided oocyte retrieval is a fundamental step in the treatment of in vitro fertilization (IVF). To date, no anesthetic technique has demonstrated superiority in terms of efficacy, tolerance or analgesia. Virtual Reality Distraction has been studied for its clinical applications. Patients will be included during the consultation with either the gynecologist or the anesthetist who will explain the protocol to the patient and give her consent to sign. After obtaining their informed consent, the patient will be randomized into two groups based on a computer-generated randomization list (QuickCalcs program; GraphPad Software Inc) either into the experimental or in the control group. In the experimental group, patients will benefit from a 20-minute virtual reality. Patients will watch a forest walk in virtual reality while listening to narrations designed to induce relaxation and meditation. If the oocyte retrieval was not completed within 20 minutes, the patient will watch the virtual reality program again. The target-controlled infusion of remifentanil and propofol will be connected to the patient, and only titrated to patient's comfort. In the control group, patients will immediately benefit from an infusion of remifentanil and propofol titrated in a well-protocolized manner according to the patient's comfort.
