Analysis On The Related Risk Factors Of Postoperative Infection In Patients With Total Knee Arthroplasty

Objective:Postoperative incision infection of artificial total knee arthroplasty is one o f the major complications which will influence prognosis and threaten to the lives of patie nts, positive treatment and look for risk factors which may induce postoperative infection will improve the prognosis and life quality of patients.Methods:This study retrospectively analyzed total knee arthroplasty medical records of560patients from January2011to December2013period in a third-grade class-A hospital of Xinjiang, we divided the infection factors into self-factors, perioperative factors and p ostoperative factors. explore the risk factor of postoperative incision infection, in order to provide guidance for clinical treatment.Results:Included in the study of artificial knee joint replacement,560cases of patients,9patients with postoperative infection, the incidence of postoperative infection was5.18%; ZuBie, body weight, different ways of operation, in patients with different knee prosthesis for total knee arthroplasty infection rate after all no effect; Male patients after total knee arthroplasty infection rate is significantly higher than female patients; Tumor around the knee joint infection rates were25.00%,11.70%infection rate, traumatic arthritis rheumatoid arthritis infection rate11.11%, knee osteoarthritis infection rate3.67%, ankylosing arthritis infection rate0%; The more basic diseases patients after total knee arthroplasty had higher rates of infection; The longer the operation time, postoperative infection is higher; The higher the ASA score, postoperative infection is higher; The more blood loss, the higher infection rate; The more amount of blood transfusion, infection rate is higher; Check out the pathogen of33strains, mainly for gram negative bacteria and gram positive bacteria, accounting for more than95%of all bacteria. pseudomonas aeruginosa, klebsiella pneumoniae, staphylococcus aureus and streptococcus pneumoniae are not shown to vancomycin resistance. Conclusion:age,gender,preoperative,diagnosis,basicdiseases,operative time,ASA score,the length of time,amount of bleeding and blood transfusion are risk factors of infected total knee arthroplasty;postoperative infection pathogens are mainly Gram-pathogen Gram-negative bacteria and gram-positive bacteria,the first four pathogens were low-level resistant to vancomycin,clinical treatment of infection after total knee arthroplpsty may be preferred to Vancomycin.
