摘要
目的调查分析医院2011年多药耐药菌的种类及分布,为控制医院感染提供科学依据。方法将医院2011年住院患者22025份细菌培养标本的相关信息导入数据库进行分析,检出阳性病原菌,再按国际标准化定义筛选出多药耐药菌。结果 22 025份标本中共培养出病原菌5408株,其中革兰阳性菌1320株占24.41%;革兰阴性菌3933株占72.72%;真菌155株占2.87%;2912株多药耐药菌标本分离自呼吸道、泌尿道、切口、血液、器官/腔隙、导管、其他部位等,分别占70.95%、10.71%、7.86%、5.60%、2.27%、0.62%、1.99%;在非手术科室检出1542株,手术科室检出1370株。结论多药耐药菌已逐渐成为医院感染的主要病原菌,应采取综合措施进行积极有效的预防与控制。
OBJECTIVE To investigate the distribution of the species of multidrug-resistant bacteria isolated in 2011 so as to provide scientific basis for the control of nosocomial infections. METHODS The relevant information of 22 025 bacterial culture specimens obtained from the hospitalized patients in 2011 were imported to a database and then was analyzed, the positive pathogens were detected, and the multidrug-resistant bacteria were screened out according to the international standard definitions. RESULTS A total of 5408 strains of pathogens were isolated from 22 025 specimens, including 1320 （24. 41%） strains of gram-positive bacteria, 3933 （72. 73%） strains of gram-negative bacteria, and 155 （2. 87%） strains of fungi. Totally 2912 strains of multidrug-resistant bacteria were isolated from the respiratory tract （70. 95%）, the urinary tract （10. 71%）, surgical incision （7. 86%）, blood （5.60%）, organ/cavity （2.27%）, catheter （0.62%）, and other sites （1.99%）. There were 1370 strains isolated from the operating rooms and 1542 strains isolated from other departments. CONCLUSION The multi drug-resistant bacteria have gradually become the main pathogens causing the nosocomial infections, it is necessary to take comprehensive measures to effectively prevent and control the nosocomial infections.
