Annual report of perioperative mortality and morbidity for the year 2000 at certified training hospitals of Japanese Society of Anesthesiologists: with a special reference to anesthetic methods--report of the Japanese Society of Anesthesiologists Com

摘要

The Committee on Operating Room Safety of Japan Society of Anesthesiologists (JSA) sends annually confidential questionnaires of perioperative mortality and morbidity (cardiac arrest, severe hypotension, severe hypoxia) to Certified Training Hospitals of JSA. This report is a special reference to anesthetic methods in perioperative mortality and morbidity in 2000. Five hundreds and twenty hospitals reported perioperative mortality and morbidity referred to anesthetic methods and total numbers of reported cases were 910,007. The percentage of cases reported by each anesthetic method was as follows; inhalation anesthesia 45.47%, total intravenous anesthesia (TIVA) 6.15%, inhalation anesthesia + epidural or spinal or conduction block 24.48%, TIVA + epidural or spinal or conduction block 6.33%, spinal with continuous epidural block (CSEA) 3.67%, epidural anesthesia 1.92%, spinal anesthesia 10%, conduction block 0.47% and others 1.49%. The incidence of cardiac arrest per 10,000 cases due to all etiology (anesthetic management, preoperative complications, intraoperative complications, surgery, others) is estimated to be 6.55 cases in average; 5.36 cases in inhalation anesthesia, 30.72 cases in total intravenous anesthesia (TIVA), 4.62 cases in inhalation anesthesia + epidural or spinal or conduction block, 2.6 cases in TIVA + epidural or spinal or conduction block, 1.2 cases in spinal with continuous epidural block (CSEA), 0.57 cases in epidural anesthesia, 1.65 cases in spinal anesthesia, 2.36 cases in conduction block and 46.38 cases in other methods. However, the incidence of cardiac arrest per 10,000 cases totally attributable to anesthetic management is estimated to be 0.54 cases in average; 0.34 cases in inhalation anesthesia, 1.07 cases in TIVA, 0.58 cases in inhalation anesthesia + epidural or spinal or conduction block, 0.17 cases in TIVA + epidural or spinal or conduction block, 0.9 cases in CSEA, 0.57 cases in epidural anesthesia, 0.99 cases in spinal anesthesia, zero case in conduction block and 1.47 cases in other methods. The incidence of severe hypotension per 10,000 cases due to all etiology is estimated to be 11.14 cases in average; 11.31 cases in inhalation anesthesia, 36.61 cases in TIVA, 9.29 cases in inhalation anesthesia + epidural or spinal or conduction block, 6.59 cases in TIVA + epidural or spinal or conduction block, 3.59 cases in CSEA, 6.3 cases in epidural anesthesia, 4.39 cases in spinal anesthesia, 2.36 cases in conduction block and 23.56 cases in other methods. On the other hand, the incidence of severe hypotension per 10,000 cases totally attributable to anesthetic management is estimated to be 1.25 cases in average; 0.97 cases in inhalation anesthesia, 0.89 cases in TIVA, 1.39 cases in inhalation anesthesia + epidural or spinal or conduction block, 1.39 cases in TIVA + epidural or spinal or conduction block, 2.09 cases in CSEA, 3.44 cases in epidural anesthesia, 1.87 cases in spinal anesthesia, zero case in conduction block and zero case in other methods. The incidence of severehypoxia per 10,000 cases due to all etiology is estimated to be 4.8 cases in average; 6.35 cases in inhalation anesthesia, 9.64 cases in TIVA, 3.82 cases in inhalation anesthesia + epidural or spinal or conduction block, 2.26 cases in TIVA + epidural or spinal or conduction block, 0.3 cases in CSEA, 1.15 case in epidural anesthesia, 1.21 cases in spinal anesthesia, zero case in conduction block and 5.89 cases in other methods. On the other hands, the incidence of severe hypoxia per 10,000 cases totally attributable to anesthetic management is estimated to be 1.98 cases in average; 3.09 cases in inhalation anesthesia, 2.32 cases in TIVA, 1.3 cases in inhalation anesthesia + epidural or spinal or conduction block, 0.87 cases in TIVA + epidural or spinal or conduction block, zero case in CSEA, zero case in epidural anesthesia, 0.55 cases in spinal anesthesia, zero case in conduction block and zero case in other methods.
