[Critical events in the operating room among 1,440,776 patients with ASA PS 1 for elective surgery].

Background: The Japanese Society of Anesthesiologists (JSA) survey of critical incidents in the operating room has shown that preoperative complications are the leading causes of critical incidents, and affect the occurrence, severity and outcome of critical incidents which are due to causes other than preoperative complications. Causes of critical events in the operating room were examind in patients for elective surgery with American Society of Anesthesiologists physical status (ASA PS) 1.

[Surgical volume and mortality due to intraoperative critical incidents at Japanese Society of Anesthesiologists certified training hospitals: an analysis of the annual survey in 2002].

Background: We have previously showed that surgical volume affects mortality due to intraoperative critical incidents among patients undergoing cardiac surgery, the surgery with the highest risk, using data obtained by the annual survey in 2001 conducted by the Japanese Society of Anesthesiologists (JSA). In this study, we investigated whether surgical volume affects mortality due to intraoperative critical incidents independent of the surgical site.

Methods: We investigated this relationship using data obtained from the 2002 annual survey conducted by the Subcommittee on Surveillance of Anesthesia-related Critical Incidents, JSA.

[Critical incidents due to drug administration error in the operating room: an analysis of 4,291,925 anesthetics over a 4 year period].

Background: Wrong drugs, overdose of drugs, and incorrect administration route remain unsolved problems in anesthetic practice. We determined the incidence and outcome of drug administration error in the operating room of Japanese Society of Anesthesiologists Certified Training Hospitals.

Methods: Data were obtained from annual surveys conducted by Japanese Society of Anesthesiologists between 1999 and 2002.

[Annual mortality and morbidity in operating rooms during 2002 and summary of morbidity and mortality between 1999 and 2002 in Japan: a brief review].

The Japanese Society of Anesthesiologists (JSA) conducts an annual survey of life-threatening events in operating rooms (OR) in JSA Certified Training Hospitals (JSACTH) by sending and collecting confidential questionnaires. Etiologies of the incidents were divided into four categories: those totally attributable to anesthetic management (AM), those resulting from preoperative complications (PC), those resulting from intraoperative pathological events (IP) and those related to surgical procedures (SP). IP resulted from coronary ischemia not suspected preoperatively, arrhythmias, pulmonary embolism, and other conditions.

[The relationship between the yearly number of operations and mortality due to intraoperative critical incidents in patients for cardiac surgery: an analysis of annual survey 2001 conducted by the Japanese Society of Anesthesiologists].

Background: The number of surgical operations performed has been reported to have a relation with surgical morbidity and mortality. In Japan, however, the relationship between surgical load and outcome has not been elucidated.

Methods: We investigated this relationship in patients for cardiac surgery using data from the 2001 annual survey concerning anesthesia-related critical incidents, conducted by the Committee on Operating Room Safety, Japanese Society of Anesthesiologists.

[Annual study of anesthesia-related mortality and morbidity in the year 2001 in Japan: the outlines--report of Japanese Society of Anesthesiologists Committee on Operating Room Safety].

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.

[Life-threatening coronary ischemia in the operating room: analysis of annual survey from 1999 to 2001 conducted by Japanese Society of Anesthesiologists].

In Japan, the incidence of cardiac morbidity among patients with ischemic heart diseases has been reported to be 13.2-16.4%, and that of perioperative myocardial infarction in these patients about 1%.
