About

At present, the elderly population in China has reached 241 million, and there are more than 20 million elderly surgical patients every year, accounting for about 25% of the surgical population. However, there is no research report on the anesthesia related risk factors of death of elderly patients in hospital. The purpose of this study is to analyze the perioperative data of multicenter database, and to explore the anesthesia related death risk factors of elderly patients with noncardiac surgery in the investigator's country, especially within 24 hours after surgery, so as to help improve the anesthesia management technology of elderly patients during surgery, improve the medical quality of perioperative period, and improve the prognosis of patients.
