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

Study Overview
=================
Brief Summary
-----------------
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.

Detailed Description
-----------------
Interventions performed under local anaesthesia may be a particular source of anxiety for some patients, and the management of surgical pain is still a real challenge. In order to avoid the side effects of medications, a lot of caregivers are turning to complementary medicines. Hypnosis in particular has long been used in the non-pharmacological management of pain and anxiety. 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. Patients requiring facial surgery under local anaesthesia in an ultra-short circuit will be informed of the study in consultation by the maxillofacial surgeon. If they give their informed consent, a State-Trait Anxiety Inventory (Spielberger Self-Assessment Questionnaire) will be given to them and collected on the same day. Each patient's anxiety score will be calculated so as to select only patients who are at least lightly anxious about their management (score ≥ 36). The latter will be randomized into 2 groups, one benefiting from experimental management based on hypnosis techniques and the other benefiting from conventional management.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| variation in Spielberger's anxiety self-assessment questionnaire score between the patient's arrival in the operating room and his departure | The State-Trait Anxiety Inventory (STAI) (or Spielbergers's anxiety self-assessment questionnaire) is a psychological inventory based on a 4-point Likert scale and consists of 40 questions on a self-report basis. The STAI measures two types of anxiety - state anxiety, or anxiety about an event, and trait anxiety, or anxiety level as a personal characteristic. Higher scores are positively correlated with higher levels of anxiety. | on the day of surgery under local anaesthesia. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Value reported by the patient on the Visual Analogue Pain Scale after surgery | The visual analogue scale (VAS) is commonly used as the outcome measure. It is usually presented as a 100-mm horizontal line on which the patient's pain intensity is represented by a point between the extremes of no pain at all and worst pain imaginable. | on the day of surgery under local anaesthesia. | 
| Variation of amount of local anaesthetic | Amount of local anaesthetic consumed for a defined surgical procedure | on the day of surgery under local anaesthesia. | 
| measure of operating time | operating time for a defined surgical procedure. | on the day of surgery under local anaesthesia. |
