【摘要】 目的了解医院导尿管相关性尿路感染的病原菌分布及耐药特征,为临床医师合理使用抗菌药物提供参考依据。方法严格按照《全国临床检验操作规程》,采集患者的尿液进行细菌培养与鉴定;采用CLSI推荐的K-B法进行药敏试验。结果 159株尿路感染病原菌以大肠埃希菌为主,占38.4%,铜绿假单胞菌第2位,占13.2%,凝固酶阴性葡萄球菌第3位,占12.6%;所有病原菌对常用抗菌药物均产生了不同的耐药性。结论临床医师应重视病原学监测,按照药敏试验结果规范用药,才能有效控制导尿管相关性尿路感染,提高临床治愈率。更多还原

【Abstract】 OBJECTIVE To understand the constituent ratio and antimicrobial resistance of pathogenic bacteria causing urethral catheter-associated urinary tract infection and offer reference for clinical use of antibiotics.METHODS Referring to National Guide to Clinical Laboratory Procedures,bacterial culture and identification were performed.The susceptibility testing was performed by K-B method as recommended by CLSI.RESULTS Among 159 strains of pathogenic bacteria,Escherichia coli(38.4%) ranked the top one,followed by Pseudomonas aeruginosa(13.2%) and coagulase-negative Staphylococci(12.6%).All of the pathogenic bacteria were resistant to commonly used antibiotics to varying degrees.CONCLUSION Clinicians should attach importance to pathogenic surveillance and reasonably use the antibiotics according to susceptibility testing results to effectively control urethral catheter-associated urinary tract infection and raise the clinical recovery rate.更多还原
