摘　　要：目的分析耐碳青霉烯类肺炎克雷伯菌(CRKP)在医疗环境中的分布特点。方法分别于2016年4月25日、8月29日对某院检出CRKP的患者周围环境进行清洁消毒前随机采样,采样类别主要为物体表面和医疗器材。分析CRKP的分布特点。结果外科ICU、呼吸ICU、急诊ICU分别采样90、41、56份。外科ICU和呼吸ICU标本中未检出CRKP;急诊ICU检出CRKP 6株,检出率为10.71%。2016年4月份采样103份,检出CRKP6株,检出率为5.83%,高于2016年8月份CRKP检出率(P<0.05)。不同标本类别、负责人类别CRKP检出率比较,差异均无统计学意义(均P>0.05)。结论应加强重点科室如急诊ICU的环境清洁消毒,减少CRKP在医疗环境中的传播。Objective To analyze the medical environmental distribution characteristics of carbapenem resistant Klebsiella pneumoniae （CRKP）. Methods On April 25 and August 29, 2016, random sampling was performed be- fore cleaning and disinfecting the surrounding of patients who isolated CRKP in a hospital, sampling were mainly object surfaces and medical devices. Distribution characteristics of CRKP were analyzed. Results The number of environmental sampling in surgical intensive care unit（SICU）, respiratory ICU（RICU）, and emergency ICU（EICU） were 90, 41, and 56 respectively. CRKP was not found in SICU and RICU specimens; 6 strains of CRKP were iso- lated in EICU, the isolation rate was 10.7l~. In April 2016, 103 specimens were taken, and 6 strains of CRKP were isolated, isolation rate was 5.83~, which was higher than in August of 2016（P〈0.05）. There were no sig- nificant differences in isolation rates of CRKP among different specimens and different responsible persons （all P〈0.05）. Conclusion Key departments, such as E1CU, should be intensified cleaning and disinfection, so as to re duce the spread of CRKP in the medical environment.
