Risk factors and preventive strategies of postoperative delirium in 209 patients with Stanford B aortic dissection:A retrospective cohort study
Objective To investigate the risk factors and prevention strategies of postoperative delirium in Stanford B aortic dissection.Methods Clinical data of the patients diagnosed with Stanford B aortic dissection and undergoing endovascular aortic repair from January 2020 to August 2021 in our department were retrospectively collected.Patients were divided into a non-delirium group and a delirium group according to the presence of postoperative delirium.The risk factors for postoperative delirium after Stanford type B aortic dissection and the protective effect of dexmedetomidine on delirium were analyzed.Results A total of 659 patients with Stanford type B aortic dissection were enrolled,including 540 males and 119 females with a median age of 58.00(41.00,75.00)years.There were 450 patients in the non-delirium group,and 209 patients in the delirium group.There was no statistical difference in gender,body mass index,hypertension,hyperlipidemia,smoking and drinking history,cholesterol triglyceride level,or creatinine glomerular filtration rate(P＞0.05).Age was an independent risk factor for postoperative delirium in Stanford type B aortic dissection(OR=1.392,95％CI 1.008-1.923,P=0.044).Moreover,whether dexmedetomidine was used or not had no effect on the duration of postoperative delirium(x2=4.662,P=0.588).Conclusion Age is an independent risk factor for postoperative delirium in patients with Stanford type B aortic dissection.The incidence of postoperative delirium in young patients is lower than that in the patients with middle and elderly age,and it may be of reference value to prevent postoperative delirium.Dexmedetomidine has no significant effect on controlling the duration of postoperative delirium.
