Under the impetus of governing bodies, learned societies, hospital management, CPPs, etc., clinical research has developed and structured considerably, in order to provide the medical community and patients with the most appropriate care, and to formulate recommendations.

In anesthesia, clinical research evaluates drugs, medical devices or care pathways. However, the general public's perception of this research in our specialty remains confidential. Several studies carried out in oncology have shown limited interest in research on the part of the general public and patients, and more often than not a lack of awareness of ethical laws and the role of french ethics committee (CPP).

By means of an anonymous questionnaire handed out at the anesthesia consultation, the investigators would like to assess patients' level of knowledge of clinical research in anesthesia, and find out how they feel about the possibility of being included in a trial.
