AbstractTo avoid the neurological deficits after neurosurgical procedures, awake craniotomy applying intraoperative awake functional brain mapping has been employed. Anesthesia for awake craniotomy requires particular attention to airway management, control of seizures and measures for decreasing the anxiety of the patients. We investigated the current status of anesthetic management for awake craniotomy in Japan to establish a standard procedure for safe anesthesia. A questionnaire was sent to 80 universities with departments of anesthesia in Japan and 34 (43%) responded. In 19 institutes, awake craniotomies are being practiced. The first experience of awake craniotomy was in 1996 in Japan and since then most of the institutes have experienced only three or fewer cases. Airway management, control of nausea and vomiting, stable awakening during functional mapping and control of seizures were pointed out as problems during awake craniotomy. Based on the present results, our experience and the information from previous investigations, standard anesthetic management for awake craniotomy in our country will be documented.
