深静脉置管的感染相关因素分析及护理

Related factors for deep venous catheter-associated infections and nursing countermeasures

目的分析深静脉置管的感染相关因素,并提出相应的护理措施。方法通过回顾分析对行深静脉置管的670例患者的临床资料进行调查,探讨导致感染的相关因素。结果深静脉置管术后感染的病例为92例,感染率为13.7%;其中男性47例,占51.1%;女性45例,占48.9%,感染病例中男性与女性感染比较,差异无统计学意义;感染组病例的年龄、置管次数、换药频次和置管留置时间与未感染组比较,差异有统计学意义(P<0.05);感染组病例的性别、体重指数和置管部位与未感染组比较,差异无统计学意义。结论患者的年龄、置管次数、换药频次和置管留置时间是深静脉置管的感染因素,值得医务工作者重视,加强工作者的操作能力和无菌操作培训以及加强适宜的护理,可降低深静脉置管感染的发生。

OBJECTIVE To analyze the related factors for deep venous catheter-related infections and propose the corresponding nursing countermeasures.METHODS A total of 670 patients who underwent deep venous catheterization were selected,the clinical data of the patients were retrospectively analyzed to find out the related factors leading to the infections.RESULTS Totally 92 out of 670 cases were infected after deep venous catheterization with the infection rate of 13.7%,there were 47（51.1%） cases of the male and 45（48.9%） cases of the female,the difference in the infection rate between the male and female was not statistically significant.The difference in the age,frequency of catheterization,frequency of change dressing,or the duration of indwelling catheter between the infection group and the non-infection group was statistically significant（P0.05）.The difference in the gender,body mass index,or the location of indwelling catheter between the two groups was not statistically significant.CONCLUSION The age,frequency of catheterization,frequency of change dressing,and duration of indwelling catheter are the predisposing factors for the deep venous catheter-related infections,to which the medical staff should attach great importance,and it is of great significance in reducing the incidence of deep venous catheter-related infections to strengthen the training of operation sill and the aseptic operation and intensify the appropriate nursing.
