Difficult Airway Management (DAM) is one of the most important skills for medical practice, especially for anesthesiologists. A seminar of DAM was held in the 51 st annual meeting of Japan Society of Anesthesiologists. It consisted of a 60-minute lecture about ASA difficult airway management algorithm, and a 120-minute hands-on training session using a mid-fidelity human simulator. The lecture was held twice, and was opened to every JSA member without pre-registration. More than 100 participants attended each lecture. The hands-on training session, which required preregistration, was held three times. Each training session was limited to 8 participants, and a total of 23 participants attended the session. The training session was restricted to only participants and staffs so that their privacy was secured. The questionnaire about DAM was collected after the lectures or the training sessions. Most of the participants of lectures were certified anesthesiologists, and they agreed that the DAM seminar was useful. The questionnaire revealed that the most popular technique for DAM was insertion of laryngeal mask airway (ILMA). Otherwise the invasive techniques were difficult to be experienced in the clinical practice. We suspected that the DAM seminar was useful, especially for the invasive technique without substitute training methods under clinical situation.
