About

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.
