目的:探讨导致血液透析患者深静脉置管发生感染的易感因素,进而降低深静脉置管感染的发生率。方法:回顾性分析笔者所在医院2010-2015年共计311例深静脉置管血液透析患者的资料,采用SPSS 13.0统计软件进行分析,分析置管感染的发生率及其易感因素。结果:338例次穿刺置管患者,感染发生率为14.20%(48例次),其中穿刺部位感染占72.92%(35例次),血培养阳性占27.08%(13例次),以革兰阳性菌为主,占49.12%。置管部位的选择与导管留置时间的长短是导致感染发生率差异的主要因素,差异均有统计学意义(P<0.05)。结论:血管通路是维持血透患者的生命线,针对易感因素进行干预对降低深静脉置管感染发生具有重要意义。
Objective: To explore the predisposing factors leading to infection of deep vein catheterization in hemodialysis patients, and then to reduce the incidence of catheterization infection in deep vein. Methods: A retrospective analysis of the author’s hospital from 2010 to 2015, a total of 311 cases of deep venous catheter hemodialysis patients with SPSS 13.0 statistical software to analyze the incidence of catheter infection and susceptibility factors. Results: The incidence of infection in 338 cases was 14.20% (48 cases), of which 72.92% (35 cases) were puncture site and 27.08% (13 cases) were positive in blood culture. Positive bacteria, accounting for 49.12%. The choice of catheter site and catheter indwelling time is the main factor leading to the difference in the incidence of infection, the difference was statistically significant (P <0.05). Conclusion: Vascular access is the lifeline of maintaining hemodialysis patients. Intervention for susceptibility factors is of great significance in reducing the incidence of catheter infection in deep veins.
