Abstract:
Objective To analyze the incidence rate and the perioperative risk factors associated with delirium after cardiac surgery.Methods We enrolled 622 patients between October 2014 and March 2015 in the department of cardiovascular surgery in Henan Provincial People's Hospital who were allocated to group PD and non-PD according to the Confusion Assessment Method(CAM) after the cardiac operation.Baseline demographics,perioperative data,and postoperative outcomes of these patients were recorded and analyzed via chi-square test and multivariate logistic regression analysis to determine the risk factors of postoperative delirium.Results Postoperative delirium was detected in 102 patients according to CAM criteria.The incidence was 16.4％.Multivariate logistic regression analysis revealed that age (OR =3.456;95％ CI:2.431-4.569),preoperative atrial fibrillation (OR =1.987;95％ CI:3.562-7.862),prolonged surgery duration (OR =1.246;95％ CI:3.164-5.982),postoperative pain (OR =5.356;95 ％ CI:1.386-9.374)were independently associated with postoperative delirium after cardiac surgery.Conclusions Delirium is a frequent complication,age,preoperative atrial fibrillation,prolonged surgery duration,postoperative pain are independent risk factors for delirium following cardiac surgery.Management according to potential risk factors may be associated with preferable therapeutic outcomes.
