Summary

This study compares hypnosis via virtual reality to sedation with commonly used intravenous anesthetic agents (propofol and remifentanil) during oocyte retrieval. The main objective of this prospective randomized controlled study will be a reduction of 50 percent of the doses of remifentanil and propofol administered during oocyte retrieval while maintaining satisfaction with the quality of care.

Detailed description

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.

Conditions

• Virtual Reality Therapy
• Fertilization in Vitro
• Propofol
• Remifentanil
• Conscious Sedation

Interventions

Type	Name	Description
DEVICE	Virtual reality distraction	Patients will be exposed to a virtual reality representing a forest walk. A reduction of at least 50 percent in the remifentanil and propofol doses required for oocyte retrieval is expected.
DRUG	Propofol-remifentanil sedation	Target controlled infusion (TCI) of remifentanil will be started at an effect concentration (Ce) of 1.5 ng/mL and TCI propofol at Ce 1.5 ug/mL. The concentration of remifentanil will be adjusted in 0.5 ng/ml increments based on hand sign from the patient with a maximum effect concentration of remifentanil at 2.5 ng/ml.
