| Objective:To explore and analyze the risk factors that may lead to the death of low-energy trauma in elderly patients with femoral intertrochanteric fracture after PFNA operation within one year and make recommendations for prolonging the life of the patients and reducing the mortality after the operation.Methods:This experiment conducted a retrospective study on the case data of 279 low-energy trauma in elderly patients with intertrochanteric fractures who underwent PFNA operation in the second affiliated hospital of University of South China from 2013 to 2019.Collect and sort out patient case data such as age,gender,fracture type,waiting time for surgery,number and type of medical complications,serum potassium,serum albumin,alanine aminotransferase,and blood urea at admission.Single factor analysis was used for the above-mentioned risk factors that may affect postoperative death of patients,and multivariate analysis was further used for significant differences.Results:The results of univariate analysis showed there are age,coronary heart disease,serum albumin <35g/L,waiting for operation over48 h,combined with more than two basic medical diseases can influence mortality of low-energy trauma in elderly patients with intertrochanteric fractures after PFNA operation within one year(P<0.05).The results of multivariate analysis of the above single factors showed: age(OR=4.303,P<0.01),combination of two or more basic medical diseases(OR=2.647,P=0.015),serum albumin < 35g/L(OR=1.978,P=0.039)is an independent risk factor for mortality of low-energy trauma in elderly patients with intertrochanteric fractures after PFNA operation within one year.Conclusions:Excluding the influence of anesthesia,age,coronary heart disease,low serum albumin level,waiting for operation over 48 h,combined with more than two basic medical diseases all have an impact on the postoperative mortality of PFNA patients,among which age,low The level of serum albumin and the combination of two or more basic medical diseases are independent risk factors for the patient’s death one year after PFNA operation. |
