Study Overview
Brief 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.

Arms & Interventions
Virtual Reality Distraction
In the experimental group, patients will benefit from a 20-minute VR. 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, patients will watch the same VR program again.The TCI remifentanil and propofol will be connected to the infusion but will be stopped and titrated if discomfort.
Intervention: Virtual reality distraction (Device)
Sedation group
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.
The concentration of propofol will be adjusted by an effect concentration of 0.5 ug/ml with a maximum of 1.5 ug/ml, in this case according to a 5-point scale
- fully awake and oriented
- drowsy
- eyes closed, responds quickly to verbal commands
- eyes closed, aroused only by mild physical stimulation
- eyes closed, not aroused by mild physical stimulation) A sedation score of 3 will be the target throughout the procedure.
Intervention: Propofol-remifentanil sedation (Drug)
Outcomes
Primary Outcomes
Dose reduction in propofol and remifentanil requirements
Time Frame: 2 hours
Total dose of propofol (mg) and remifentanil (mcg) will be recorded in each group. A reduction of at least 50 percent of propofol and remifentanil doses will be expected in order to conclude on a superiority of the virtual reality distraction.
Secondary Outcomes
- Patient's comfort(4 hours, during surgery)
