摘　　要：目的对一起中心静脉置管后菌血症暴发感染进行调查分析,探讨防治措施,为预防和控制医院感染提供参考依据。方法对肿瘤内科4例患者在2008年8月4日-8日期间因中心静脉置管后菌血症暴发流行进行调查分析。结果4例患者血培养、中心静脉导管尖端和治疗室台面等均分离出产酸克雷伯菌,且药物菌谱完全一致。结论此次产酸克雷伯菌引起的菌血症为局部暴发流行。部分人员无菌观念淡薄、无菌操作执行不严可能是引起此次感染的主要原因。提示中心静脉置管者,一旦出现不明原因的感染症状,应考虑中心静脉置管因素。Objective To study epidemiological features of fulminant bacteremia caused by central venous catheterization and find measurements to prevent,control and treat nosocomial infection.Method 4 cases of inpatients who developed Klebsiella oxytoca bacteremia after central venous catherization during August 4 to 8,2008,were studied retrospectively.Result Klebsiella oxytoca had been isolated from the hemoculture,tip of the central venous catheter and the working surface of therapeutic room.The resistant spectrum of the KlebsieUa oxytoca isolated from the 4 inpatients＇ hemoculture was in accordance with that from the environment. Conclusion The infection was a localized one. The main reasons of the infection could have been lack of aseptic concept and aseptic operation. Once the patients with the eentral venous catheter shows the symptoms of unknown infection, the eentrat venous catheter should be included as one the possible reasons.
