ABSTRACT

Objective To investigate the risk factors for postoperative delirium in patients undergoing spine operation under total intravenous anesthesia. Methods Two hundred patients undergoing elective spine operation were included in this study. Patients' perioperative informations were recorded. The diagnosis of delirium was based on Confusion Assessment Method (CAM). The patients were divided into 2 groups according to the occurrence of delirium within 3 days after operation postoperative delirium group and no postoperative delirium group. Multivariate logistic regression was used to analyze the risk factors for postoperative delirium. Results Postoperative delirium developed in 39 patients during the first three postoperative days. The incidence of postoperative delirium was 19.5%. The logistic stepwise regression analysis indicated that the risk factors for delirium included age, intraoperative blood loss and alcohol abuse. Conclusion Age, large amount of intraoperative blood loss and alcohol abuse are risk factors for postoperative delirium in patients undergoing spine operation under total intravenous anesthesia.
