老年全膝关节置换患者术后感染的手术室危险因素分析

Analysis of risk factors of postoperative infection in elderly patients undergoing total knee arthroplasty

目的:探讨分析老年全膝关节置换(TKA)患者术后感染的危险因素并提出相应护理预防措施。方法:选取我院2015年1月~2017年6月期间收治的老年TKA患者192例为研究对象,根据术后是否感染分为感染组和未感染组,采用单因素和logistic多元回归分析老年TKA术后感染危险因素,并制定相应手术室护理预防措施。结果:经单因素分析,感染患者和非感染患者在血红蛋白水平、是否为接台手术、术中是否有参观、手术时间方面差异有统计学意义(P<0.05);经多因素分析,血红蛋白水平低下、接台手术、术中有人员参观以及手术时间长是老年TKA术后感染的独立危险因素(P<0.05)。结论:老年TKA术后感染独立危险因素有血红蛋白水平低下、接台手术、术中有人员参观、手术时间时间长,进行护理预防干预可降低术后感染率。

Objective： To explore and analyze the risk factors of postoperative infection in elderly patients with total knee replacement（ TKA） and put forward corresponding preventive measures. Methods： To select 192 cases of aged TKA patients treated in our hospital from January 2015 to June 2017 as the subjects of study. They were divided into infection group and uninfected group according to whether they were infected after operation or not. Single factor and logistic multiple regression analysis were used to analyze the risk factors of infection after TKA in the elderly,and the corresponding preventive measures of operation room nursing were made. Results： By single factor analysis,there were statistically significant differences between infected and non-infected patients in hemoglobin level,whether the patients were receiving surgery,whether there were visits during operation,and the time of operation（ P〈0. 05）.After multiple factor analysis,low hemoglobin level,operation,visit by personnel during operation and long operation time were the independent risk factors of infection after TKA in the elderly（ P〈0. 05）. Conclusion： The independent risk factors of infection after TKA were low hemoglobin level,operation,visit during operation and long time of operation. Nursing and preventing dryness could reduce postoperative infection rate.
