Abstract:
Objective To investigate the risk factors for postoperative delirium in patients undergoing noncardiac surgery. Methods From September-December 2009, 480 patients undergoing elective noncardiac surgery were included in this study. The criteria for enrolment of the patients in this study were (1) age ≥ 65 yr,(2) age ＜ 65 yr if associated with coronary artery disease, hypertension, diabetes mellitus, brain injury, cerebral hemorrhage, cerebral infarct, emphysema, chronic bronchitis; duration of operation ≥ 3 h and intraoperative blood loss was expected to exceed 20% of blood volume. The diagnosis of delirium was based on Confusion Assessment Method (CAM). Multivariate logistic regression was used to analyze the risk factors for postoperative delirium.Results Postoperative delirium developed in 79 patients during the first three postoperative days. The incidence of postoperative delirium was 16.5%. The logistic stepwise regression analysis indicated that the risk factors for delirium included advanced age, method of anesthesia, long operation, postoperative pain, emphysema and alcholic. Conclusion Age, method of anesthesia, long operation, postoperative pain, emphysema and alcholic are risk factors for postoperative delirium in patients undergoing noncardiac surgery.
