In adults, it is common to perform a number of superficial and non invasive surgeries under local anesthesia in order to limit the use of general anesthesia.

Hypnosis is a nonpharmacological therapies that can be used during surgery to improve the patient comfort and experience. The benefit of this practice has been widely demonstrated in adults, decreasing perioperative anxiety, postoperative pain scores as well as nausea and vomiting.

In pediatric surgery, hypnosis is an effective technique for the management of preoperative anxiety. It is used by many teams in their daily practice, particularly during anesthetic induction.

For 2 years, the team of pediatric anesthesia and surgery of the Montpellier University Hospital also offers for selected short and superficial non-invasive surgeries, an intraoperative management under hypnosis in association with ocal anesthesia as an alternative to general anesthesia. If this clinical practice of hypnosis is fully accepted and recognized in our intraoperative surgical unit, to date, no studies have evaluated the benefits of this technique compared to general anesthesia.

The objective of the study is to compare the impact of these techniques (hypnosis vs. general anesthesia) on postoperative experiences of children (rehabilitation time, anxiety, pain, nausea and vomiting, negative behavioral disorders).
