目的了解血管内置管后感染的病原学,加强预防控制和消毒措施。方法采用回顾性调查方法,对2004.1~2008.6年本医院住院患者血管内置管感染病原菌及其耐药性进行了调查。结果浅静脉、深静脉留置、外周中心静脉置管留置、中心静脉插管留置、血透和人工肝等动静脉穿刺置管留置患者共5986例,发生置管相关性感染86例,感染发病率为1.44%。感染病原菌主要为革兰阳性球菌87例,占60.8%;革兰阴性杆菌47例,占32.9%;真菌9例,占6.3%。多数致病菌对临床常用抗生素产生耐药。结论引起血管置管后感染的致病菌以革兰阳性球菌为主,多数对抗生素耐药。
Objective To understand the etiology of infection after vascular intima, to strengthen the prevention and control and disinfection measures. Methods A retrospective survey was conducted to investigate the pathogenic bacteria and their drug resistance of blood vessels in hospitalized patients from 2004 to 2008.6 years. Results A total of 5986 patients were enrolled in this study, including 5986 cases of venous catheterization, catheterization-related infection, 86 cases of infection, Is 1.44%. The main pathogens of infection were gram positive cocci 87 cases, accounting for 60.8%; gram-negative bacilli 47 cases, accounting for 32.9%; fungi in 9 cases, accounting for 6.3%. Most pathogens are commonly used in clinical antibiotics. Conclusion The pathogens that cause vascular infection after infection are mainly Gram-positive cocci, most of which are resistant to antibiotics.
