目的研究人工全膝关节置换术患者手术切口感染的危险因素,采取预防护理对策。方法采用回顾性调查方法,对某医院实施人工全膝关节置换术患者手术切口感染情况及其影响因素进行调查与分析。结果共调查人工全膝关节置换术患者352例,发生切口感染11例,切口感染率3.13%。类风湿性关节炎、高血压、糖尿病等基础疾病、既往有膝关节手术史及NNIS指数高的患者是膝关节感染的高危人群。手术方式、异体输血、术后引流、术后住院时间、术后尿路感染是膝关节感染的高危因素。结论膝关节切口感染是多因素作用的结果,应在不同时期对膝关节置换的患者采取预防措施,消除危险因素。
Objective To study the risk factors of surgical incision infection in patients undergoing artificial total knee arthroplasty and to take preventive measures. Methods A retrospective survey was conducted to investigate the surgical incision infection and its influencing factors in patients undergoing total knee arthroplasty in a hospital. Results A total of 352 cases of artificial total knee arthroplasty were investigated. Incision infection occurred in 11 cases and incision infection rate was 3.13%. Rheumatoid arthritis, high blood pressure, diabetes and other underlying diseases, history of knee surgery and NNIS index in patients with high past knee joint infection in high-risk groups. Surgical methods, allogeneic blood transfusion, postoperative drainage, postoperative hospital stay, postoperative urinary tract infection are risk factors for knee joint infection. Conclusions Infection of knee incision is the result of multifactorial action. Preventive measures should be taken in patients with knee joint replacement at different stages to eliminate the risk factors.
