ABSTRACT
Postoperative delirium involves attention and cognitive impairment and is a common, serious and often fatal condition in the elderly.This review summarizes the definition, diagnosis, pathogenesis, risk factors, prevention and treatment of postoperative delirium in elderly patients with hip fractures.
ABSTRACT
Objective@#To investigate the prevalence of postoperative delirium(PD)and its risk factors in patients aged 80 and over with hip fracture treated with total hip arthroplasty(THA).@*Methods@#Clinical history and perioperative data of patients aged 80 years and over with hip fractures who underwent THA in our hospital from Sep.2017 to Mar.2019 were analyzed.Patients were divided into delirium group and non-delirium group.The prevalence of postoperative delirium of THA and its risk factors were analyzed by multiple Logistic regression.@*Results@#A total of 90 patients were eligible for inclusion for this study.Of them, 27 patients(30.0%)were diagnosed as PD and 63(70.0%)did not experience PD.Multivariate stepwise Logistic regression analysis showed that a history of stroke(OR=17.702, 95%CI: 1.514-207.034, P=0.022), preoperative lower serum albumin(OR=1.524, 95%CI: 1.132-2.051, P=0.005), Mini-Nutritional Assessment short-form score(MNA-SF)(OR=1.481, 95%CI: 1.045-2.099, P=0.027)were independent risk factors for PD.@*Conclusions@#The prevalence of postoperative delirium of THA is higher in patients aged 80 years and over with hip fractures.Prevention and correction of risk factors, such as malnutrition, may help prevent the postoperative delirium.
