ABSTRACT

Objective To survey the status of nosocomial infection after total knee arthroplasty,analyze the risk factors of nosocomial infection and possible prevention measures.Methods Datas were collected retrospectively on 80pmients (80 knee joints) who were treated by total knee arthrophsly,the patients were divided into two groups,group A with nosocomial infection and group B without nosocomial infection.Statistic patient's age,basic diseases situation,preoperative hemoglobin content,serum albumin,operation time,blood transfusions,indwelling urethral catheter time,antibiotic treatment time of the two groups.And study the location,pathogenic bacteria and outcomes of the nosocomial infection patients.Results 10 patients occured nosocomial infection,the infected site in turn is urinary tract in 5 cases,respiratory tract 4 cases,skin infections in 1 case,the incidence of nosocomial infection is 12.5％.In noscomial infection group,patient's age,blood transfusions,operation time and postoperative indwelling urinary canal time significantly higher than no nosocomial infection group,anemia,hypoalbuminemia have relevance of nosocomial infection,there is no difference between the two groups in basic diseases situation.Conclusions The nosocomial infection after total knee arthroplasty caused by multiple factors,patient's age,hypoalbuminemia,anemia,operation time and indwelling urethral catheter time is closely related with nosocomial infection
