Conversational Hypnosis for Peripherical Veinous Access (HYPNACESS)

Study Overview
=================
Brief Summary
-----------------
The peripherical veinous catheterization is required for anesthesia. However, it's a painful procedure and causes stress or even phobia. Hypnosis can be seen as an interesting tool. Conversational hypnosis needs no training. It is used by script, which makes it easier. The working hypothesis for study is that the conversational hypnosia script reduces pain during the set up of peripherical veinous access. The main objective is the analgesia assessment of conversational hypnosis script for peripherical veinous catheter set up versus standard script in operating room. A nurse anesthetist is reading the conversational script or standard script during the procedure. The nurse anesthetist is untrained for hypnosis. The secondary objective are the level of anxiety, patient satisfaction within the perioperative period (EVAN G questionnaire), the heart rate and the evaluation how nurse anesthetist feels about using the script after each use.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Analgesia assessment by digital pain scale | Digital pain scale: it describes the severity of the pain On this scale, 0 represents no pain and 10 represents the worst possible pain | immediately after applying the peripherical veinous catheter dressing | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Level of anxiety by numerical scale | Digital scale: it describes the severity of the pain On this scale, 0 represents no anxiety and 10 represents the worst possible anxiety | before randomization and immediately after peripherical veinous catheter set up | 
| patient satisfaction within the perioperative period (EVAN G questionnaire) | EVAN G questionnaire: Score from 0 to 100 The higher the score, the higher the level of patient satisfaction | between 4 and 48 hours after the procedure | 
| Heart rate | maximum heart rate | during the procedure | 
| Nurse anesthetist feeling about using the script after each use by digital scale | Evaluate how nurse anesthetist feels about using the script after each use by digital scale ranging from 0 to 10. On this scale, 0 represents  uncomfortable and 10 represents  very comfortable  | immediately after procedure |
