Pre-anesthesia visit for scheduled surgery is mandatory by law in France. During this visit, patients should be informed of the different available technics of anesthesia (i.e. general or loco-regional) and of their own risks .

Nowadays, many informations are given through written paper and leaflets, just before the consultation. In addition, patients need usually to wait for the doctor. This time may be used to give information, and new information's support, such as videos, may be used.

The aim of this study is to evaluated if a robot (PEPPER), who is able to answer to patients and to give informations, may increase the satisfaction of patients having a pre anesthesia visit for a scheduled surgery.
