【摘要】：目的探究血液净化患者导管相关性感染的危险因素及预防措施。方法选取于2014年12月-2016年12月医院收治的120例血液净化患者作为本次研究对象,所有患者均为中心静脉置管,置管方式为锁骨下静脉、颈内静脉或股静脉置管,收集所有患者详细资料,观察患者是否发生导管感染,将感染患者导管血培养并进行病原菌分析,统计感染率,对可能引发导管相关性感染的危险因素进行统计分析。结果本次120例血液净化患者中,共22例发生导管相关性感染,感染率18.33%;检出病原菌22株其中革兰阳性菌为14株,以表皮葡萄球菌占27.27%为主;革兰阴性菌7株,以铜绿假单胞菌占13.63%为主;真菌1株,占4.55%;年龄65岁、穿刺≥2次、留置导管时间≥4周、有侵入性操作史、血清白蛋白≤35g/L、血红蛋白≤90g/L、医护人员插管技术低、住院时间≥2周、未使用抗菌药物治疗及合并糖尿病等基础疾病是诱发血液净化患者发生导管相关性感染的高危影响因素。结论诱发血液净化患者发生导管相关性感染的危险因素较多,应坚持严格无菌操作原则,对有高危因素的患者预先采取针对性措施,合理使用抗菌药物。
[Abstract]:Objective to explore the risk factors and preventive measures of catheter-related infection in patients with blood purification. Methods 120 patients with blood purification were selected from December 2014 to December 2016 as the study. The object. All the patients were catheterized by central vein, the way of catheterization was subclavian vein, internal jugular vein or femoral vein. The detailed data of all patients were collected to observe whether catheterization occurred. The blood samples of infected patients were cultured and the pathogenic bacteria were analyzed, the infection rate was counted, and the risk factors that might lead to catheter-related infection were statistically analyzed. Results in this 120 cases of blood purification, the risk factors were analyzed. There were 22 cases of catheter-related infection, the infection rate was 18.33%. Of 22 strains of pathogenic bacteria, 14 were Gram-positive, and 27.27% were Staphylococcus epidermidis. Among 7 Gram-negative strains, 13.63% were Pseudomonas aeruginosa. 1 strain of fungi (4.55%); Age 65 years, puncture 鈮，
