Assessment of the Influence of the Virtual Reality Headset on Pain and Anxiety During Oocyte Retrieval Under Local Anesthesia

Medically Assisted Reproduction provides help to infertile couples, single women and couples of women with a pregnancy project, and to women who wish to preserve their gametes. In the context of In Vitro Fertilization (IVF), oocyte donation or oocyte preservation, it is necessary to perform an oocyte stimulation, followed by an ovarian puncture in order to retrieve mature oocytes. Several types of anesthesia can be used for this procedure: general anesthesia, local anesthesia and spinal anesthesia. The puncture can also be performed under hypnosis, but this practice is difficult to generalize, as it requires specific training. None of these different types of anesthesia has proven to be superior in terms of number and quality of oocytes collected, so the choice is left to the patient. General anesthesia is mostly chosen at Rennes, although it exposes to more risks and represents a higher socio-economic cost. Improving the comfort of these patients during oocyte retrieval is a priority, especially since they may have to undergo several successive retrievals during their treatment. What if virtual reality could be a way to improve the comfort of these patients? Indeed, this technology, which allows activity in an artificial 3-dimensional world, is considered as a non-pharmacological tool for pain management and its use during surgery would also reduce the level of anxiety. In our study, during the oocyte retrieval under local anesthesia, the patients randomized in the experimental group will wear a virtual reality headset diffusing an atmosphere considered as relaxing. The expected results of this work would be a significant decrease in pain during oocyte retrieval under local anesthesia in patients wearing the virtual reality headset, associated with a decrease of anxiety and a significantly higher satisfaction score. The final objective would be to consider this tool as a non-invasive means that could be used in routine in the department of Medically Assisted Reproduction of Rennes, but also in other cities. In the longer term, the reduction of pain and anxiety could encourage patients to choose local anesthesia and therefore increase its use. Observational, prospective, randomized, open-label, monocentric study.

Evaluation of the Effectiveness of Hypnosis Support on Patient Perception of Outpatient Surgery Under Local Anaesthesia

Many clinical trials assessing the effectiveness of hypnosis have been conducted in recent years, some of which show that hypnosis reduces pain perception better than drug treatments administered to control groups, and that it is at least as effective as other complementary therapies (such as massage, acupuncture, yoga). However, their conclusions are limited by a significant risk of bias, and further studies with rigorous methodology remain necessary. The hypothesis of this study is that hypnosis support methods can reduce anxiety in patients requiring facial surgery under local anaesthesia, and thus improve their medical management. The purpose of this study is to evaluate the effectiveness of hypnosis support on the patient's state of anxiety before and after outpatient surgery under local anaesthesia in the Maxillofacial Surgery Department.
