Abstract：Objective To analyze risk factors for perioperative death and the role of anesthesia grade in the risk assessment of periopera-tive mortality.Methods From January 2007 to December 2010,there were a total of 106,630 cases of surgery in Xiangya Hospital of Central South University,214 of which were postoperatively fatal.Structured questionnaires were used to collect basic information of patients and risk factors,and multivariate analysis of Cox model was used to screen the risk factors of perioperative mortality.Results The distri-bution of 214 death cases in ASA grade showed that the number of cases per grade did not increase with the grade.In the distribution of anesthesia grade,the number of patients in each grade increased with the increase of grade levels.Multivariate analysis showed that patients with trauma had a 59％higher risk of death.Patients with cardiovascular risk events(CRE)had a 38％increased risk of death;the risk of perioperative death increased by 45％for each step higher anesthesia grade.For the deteriorated heart function,the risk of death rose 41％.Conclusion Trauma,anesthesia grade,cardiac function classification and CRE were correlated with perioperative death.For each additional elevation of anesthesia grade levels,the risk of perioperative death increased by 45％.Anesthesia grade was a good representative criterion for the risk assessment of perioperative death.
