【摘要】 目的了解该院鲍曼不动杆菌临床分布特征及耐药率变迁情况,为临床合理用药和院内感染管理提供依据。方法回顾分析该院2005年1月至2013年12月检出的鲍曼不动杆菌,分析其科室分布、标本分布及耐药率变化情况。结果 9年共分离出964株鲍曼不动杆菌,其中713株为多重耐药菌。2005~2008年分离量较少,分别为30株、26株、22株、19株。2009年和2010年开始增多,分别为65株和50株,2011年开始检出率剧增,2011~2013年分别为157株、229株、366株。9年中分离率最高的前三位科室为ICU、神经外科和呼吸科,标本来源始终以呼吸道标本为主,分泌物标本其次,近几年来血液、尿液及引流液等标本检出率有所增加。13种药物耐药率总体呈上升趋势,至2013年部分药物耐药率有一定下降。结论鲍曼不动杆菌易引起院内感染且不易清除,在重症患者集中科室高发,呼吸道感染是其主要致病类型,耐药性严重,多重耐药和泛耐药菌株比例较高,临床应依据药敏结果合理用药,配合控感部门做好消毒隔离工作,防止院内感染爆发。更多还原

【Abstract】 Objective To understand the clinical distribution characteristics of Acinetobacter baumannii in our hospital and the change situation of drug resistance rates to provide a basis for the clinical rational drug use and the nosocomial infection management.Methods The Acinetobacter baumannii strains isolated in our hospital from January 2005 to December 2013 were performed the retrospective analysis on its department distribution,specimen distribution and change of drug resistance rates.Results 964 strains of Acinetobacter baumannii were isolated during these 9years,in which 713 strains were multi-drug resistant.The isolated strains were less during 2005-2008,which were 30,26,22,19 strains respectively.The isolated strains began to increase during2009-2010,which were 65,50 strains respectively.The detection rate began to enormously increase from 2011,which were 157,229,366 strains respectively from 2011 to 2013.The top three departments of the highest isolation rates during these 9years were ICU,neurosurgery department and respiratory department.The specimen source was always dominated by the respiratory tract specimens,followed by the secretion samples,in recent years,the detection rates of blood,urine and drainage specimens were increased to some extent.The drug resistance rates in 13 kinds of drugs totally showed the increasing trend,the resistance rate of partial drugs was decreased to some extent.Conclusion Acinetobacter baumannii easily cause nosocomial infections,which is difficult to be eliminated and has high occurrence in the departments centralized with critical patients.The respiratory infection is the main pathogenic type.Its drug resistance is serious,multi-drug resistant and pan-resistant strains have the higher proportion.Clinic should rationally use the drugs based on the drug susceptibility test results,coordinates with the infection control departments for doing disinfection and isolation well and prevent ing the outbreak of nosocomial infections.更多还原
