目的：分析本院老年危重患者中心静脉导管相关性血流感染的临床特点、菌群分布及药敏情况。方法回顾性分析2012年1月～2014年1月沈阳市第四人民医院ICU住院并留置深静脉导管的136例老年患者资料，计算导管相关性血流感染发生率，分析菌群分布及药敏情况。结果136例患者导管感染发生率为3.82‰；病原菌检出11株，分别为金黄色葡萄球菌3株、凝固酶阴性葡萄球菌1株、肺炎克雷伯杆菌2株、大肠埃希菌1株、铜绿假单胞菌1株、鲍曼不动杆菌1株、粘质沙雷菌1株、白色念珠菌1株。药敏结果提示6株革兰氏阴性菌耐药性较高，分离的革兰氏阳性菌为MRCN和MRSA，均对万古霉素敏感。结论在本次调查老年危重患者中心静脉导管相关性感染中，病原菌以G杆菌为主，药敏结果提示对常见抗菌药物的耐药性较高。

Objective Analysis of clinical characteristics of catheter-related bloodstream infection in critical y il elderly patients in our hospital, flora distribution and drug sensitivity. Methods A retrospective analysis of Fourth People's Hospital of Shenyang city in 2012 January to 2014 January ICU hospitalization and deep vein indwel ing catheter in 136 cases of elderly patients with data, calculation of catheter-related bloodstream infection rate, analysis of flora distribution and drug sensitivity. Results The incidence rate was 3.82 per thousand in 136 cases of patients with catheter infection;pathogenic bacteria were detected in 11 strains were 3 strains of Staphylococcus aureus, 1 strains of coagulase negative staphylococcus, Klebsiel a pneumonia 2 strains, 1 strains of Escherichia coli, 1 strains of Pseudomonas aeruginosa, Acinetobacter, Bauman 1 strains of Serratia marcescens 1 strains, 1 strains of Candida albicans. The drug sensitivity results showed 6 strains of gram negative bacteriahad a high drug resistance, gram positive bacteria separation for MRCN and MRSA were sensitive to vancomycin. Conclusions In the center of infection in patients with the survey of critical elderlyvenous catheter-related, pathogenic bacteria with G-bacil i,Yao Minresults suggest for higher resistance to common antimicrobial agents.
