Checking the anaesthetic machine before its daily use is essential. The aim of our study was to evaluate, through the use of an anonymous questionnaire, how the anaesthetists of our institution (physicians and nurses) report their daily checking. Sixty-three questions were used to ask the participants how frequently they checked the main components of the anaesthetic machine; the answers were evaluated with a score (0–3). The overall response rate was 78%, nurses' rate being lower than physicians' rate. Nurses obtained a higher global score, which raises the question of different adherence to guidelines by nurses and physicians. Moreover, questions in relation to gas supply were badly scored by all participants, which should alert us to reinforce theoretical and practical training in these items. Finally, although the methodology used in this survey could raise the question of the best way to evaluate the actual checkout procedure, self-reported assessment remains an alternative to more complex and expensive methods, such as an observer or a video evaluation.
