We reported anesthesia-related mortality and morbidity in Japanese Society of Anesthesiologists Certified Training Hospitals (JSACTH) in the year 2001, as a part of the second series of annual studies in the identical questionnaires form started in 1999. JSA Committee on Operating Room Safety sent confidential questionnaires to 813 JSACTH and received effective answers from 87.9% of the hospitals. A total number of 1,284,957 anesthetics were documented. ⋯ Three major causes of all critical incidents in 52 detailed classification of principal causes were preoperative hemorrhagic shock (31.4%), massive hemorrhage due to surgical procedures (16.9%), and preoperative multiple organ failure/sepsis (9.0%). In conclusion, the obtained incidences as to cardiac arrest and death, either in total number during anesthesia/surgery or in that due to anesthetic management, kept decreasing lineally through 8 years study in 1994-2001. We expect that this second series of annual studies for five-years should reveal precise and definite direction for us to reduce anesthesia-related mortality and morbidity by analyzing further detail with special reference to ASA physical status, age distribution, surgery sites and anesthetic methods.
