Analysis On Risk Factors Of Surgical Site Infection After Hip Replacement For Transcervical Fracture

Objective: To analyze the risk factors related to surgical site infection(SSI)after hip replacement for transcervical fracture by single factor and multifactor study in two groups,so as to provide reference for effective prevention of SSI and reduce the incidence of SSI.Method: From January 2011 to December 2017,a retrospective study was conducted on the patients who underwent hip replacement for transcervical fracture in the department of traumatic orthopaedics of our hospital,a total of 283 cases within 7 years after screening strictly according to the inclusion and exclusion criteria met the research requirements,among them,272 cases without SSI after hip replacement were selected as the control group(139 males and 133 females),11 cases of SSI after hip replacement were included in the study group(9 males,2 females).Compared two groups of patients in age,gender,admission path,history of ICU treatment,history of diabetes,chronic steroid hormone history,preoperative nutritional status,type of anesthesia,operative method,operation duration,time of indwelling drainage tube and perioperative allogeneic blood transfusion amount of influence on the incidence of postoperative surgical site infection.Results: Single factor comparison analysis shows that the two groups in age,gender,history of ICU treatment,history of diabetes,chronic steroid hormone history,anemia,serum albumin value,operation duration,time of indwelling drainage tube and perioperative allogeneic blood transfusion differences have statistical significance.There was no statistical difference in the admission path,type of anesthesia and operative method.Further multivariate Logistic regression analysis of the above statistically significant factors showed that,age,history of ICU treatment,hypoproteinemia,duration of surgery >180min and volume of allogeneic blood transfusion >800ml were independent risk factors for SSI after hip replacement.Conclusion: The risk of SSI in patients with advanced age,history of ICU treatment,hypoproteinemia,long operation time and large amount of perioperative allogeneic blood transfusion will be significantly increased after hip replacement.
