Abstract:
Objective To determine the risk factors for post-operative delirium(POD)and post-operative cognitive dysfunction(POCD)in patients undergoing spine surgery.Methods One hundred and twenty ASA Ⅰ-Ⅲ of both sexes aged 50-76 yr undergoing elective spine surgery under general anesthesia were studied.POD was assessed by Delirium Rating Scale revised 98 at 2 days after operation and the patients were assigned into POD and nonPOD group.Cognitive function was assessed by Mini-Mental State Examination(MMSE)at 1 day before and 3 days after operation.The patients were diagnosed as having POCD if MMSEpre-MMSEpost ≥ 3.The palients were assigned into POCD and nonPOCD group.Executive function and depression were assessed by stroop interference test and Beck Depression Inventory(BDI)at 1 day before operation.Age,sex,education,alcohol consumption per week,a history of psychiatric disease,ASA physical status,Charlson comorbidity score,type of anesthesia,anticholinergic drug administration and VAS score at 1 day after operation were recorded.If there was signifirant difference between the 2 groups,the factor was analyzed using multi-factor logistic regression to select risk factor for incidence of POD and POC).Results Eleven patients developed POD(9.2％)and 30 patients developed POCD(25.0％).Logistic regression model showed that lower Stroop-CW,higher BDI score,higher Charlson comorbidity score and a history of psychiatric disease were risk factors for POD,while lower Stroop-CW,higher BDI score,higher Charlson comorbidity score and higher alcohol consumption per week were risk factors for POCD.Conclusion Preoperative executive dysfunction,depression and greater preoperative comorbidity are risk factors for both POD and POCD.A history of psychiatric disease is a risk factor for POD and higher alcohol consumption is a risk factor for POCD in patients undergoing spine surgery.
