title: [Perioperative mortality and morbidity for the year 1999 in 466 Japanese certified anesthesia-training hospitals: with special reference to operative regions--report of Committee on Operating Room Safety of Japanese Society of Anesthesiologists].
abstract: Perioperative mortality and morbidity in Japan for the year 1999 were analyzed retrospectively with special reference to operative regions. The total number of analyzed cases was 701,940. The percentages for each operative region were as follows, craniotomy 4.5%, thoracotomy 3.3%, heart and great-vessels 3.9%, thoracotomy with laparotomy 0.8%, laparotomy except caeserian-section 31.7%, ceserian-section 3.2%, head-neck and otolarynx 14.5%, chest-abdomen-perineum 11.1%, spine 3.5%, extremity including peripheral-vessel 16.5%, and others 6.9%. The incidence of serious events, including cardiac arrest and severe hypotension and hypoxemia suggesting impending cardiac arrest was 34.58 per 10,000 cases in all operative regions. The events were observed more frequently in heart and great-vessels 247.26, thoracotomy with laparotomy 128.91 and thoracotomy 61.55, and less frequently in chest-abdomen-perineum 13.52 and extremity including peripheral-vessel 16.99. Regarding the prognosis of events, the cases with no sequela were 69.9% in all operative regions. While there were fewer cases with no sequela in craniotomy 50.4%, thoracotomy with laparotomy 54.3% and heart and great-vessels 58.6%, there were more cases in head-neck and oto-larynx 95.2% and chest-abdomen-perineum 90.5%. The incidence of serious events totally attributable to anesthetic management was 7.79 per 10,000 cases in all operative regions. The events were observed more frequently in thoracotomy 12.82, heart and great-vessels 12.29 and spine 11.06, and less frequently in extremity including peripheral-vessel 5.17 and chest-abdomen-perineum 6.05. Regarding the prognosis of events, the cases with no sequela were 93.1% in all operative regions. There were fewer cases with no sequela in thoracotomy with laparotomy 80.0% and craniotomy 81.8%. The main cause of events in thoracotomy and spine was the inadequate airway management, and in heart and great-vessels was the overdose or miss-selection of drugs. Although the incidence of serious events totally attributable to anesthetic management was one fourth of all events, most of them resulted from human factors. Thus, the more efforts are necessary to improve the outcomes. While the total deaths from 701,940 cases, including death on the operation day or within 7 days after it, were 528 cases (7.52 per 10,000 cases), the deaths totally attributable to anesthesia were 7 cases (0.10 per 10,000 cases).
