老年住院患者产ESBLs-ECO的检测与耐药性研究

本研究结果显示,观察组较对照组治疗总有效率和咳嗽消失率均明显提高袁咳嗽症状评分显著改善，咳嗽消失时间明显缩短,说明采用苓甘五味姜辛汤联合复方甲氧那明治疗慢性咳嗽，可明显提高治疗效果,改善咳嗽症状，缩短咳嗽消失时间，疗效优于单一复方甲氧那明治疗，值得临床推广。

老年住院患者产ESBLs-ECO的检测与耐药性研究

高弘

[摘要1目的分析老年住院患者感染产E SB L s-E C O的临床分布特点及耐药性，为临床合理使用抗菌药物提供依据。方法回顾性分析医院2011年1月~2015年12月老年住院患者分离出的696株E C O中的产E SB L s-E C O检出率、临床分布及耐药性检测结果。结果696株E C O中，共检出393株产E SB L s-E C O(56.47%)，IC U、急诊科、肿瘤科检出率居前3位，分别为25.70%、16.03%和14.25%;尿液、痰液和血液标本检出率居前3位，分别为33.08%、20.87%和13.49%;产E SB L s-E C O对磺胺甲噁唑/甲氧苄啶耐药率最高为98.47%,对庆大霉素、哌拉西林、妥布霉素、头孢唑林耐药率均高于90.00%;产E SB L s-E C O与 非产E SB L s-E C O均对亚胺培南、阿米卡星较敏感，耐药率均低于3%,产E SB L s-E C O对临床其他临床常用抗菌药物均存在较高耐药率，且显著高于非产E S B L s-E C O(P<0.05)。结论产E SB L s-E C O耐药现象严重，临床应加强合理用药指导，并加强IC U、急诊科、肿瘤科等科室的监测，以减少产E SB L s-E C O感染的发生和传播。

Detection and drug resistance of ESBLs-ECO production in senile hospitalized patients

Gao Hong Department of Laborator^^, Daxian People's Hospital, Dazhou, Sichuan, 635000, China

^^^^ective To analyze the clinical distribution characteristics and drug resistance of ESBLs-ECO production in senile hospitalized patients and provide basis for clinical reasonable application of antibacterials. M eAods The detection rate, clinical distribution and drug resistance detection results of the ESBLs-ECO production in the 696 strains of ECO from senile patients admitted to our hospital from January 2011 to December 2015 were analyzed retrospectively. Resulte Among the 696 strains of ECO, 393 strains with ESBLs-ECO production (56.47%) were detected. The detection rates in ICU, Emergency Department and Department of Oncology "were the top three, 25.70%, 16.03% and 14.25%, respectively; the detection rates in urine, sputum and blood samples were the top three, too, 33.08% , 20.87%and 13.49% , respectively. The rate of the resistance of ESBLs-ECO production to sulfapirazinmetossina/trimethoprim was the highest, 98.47% , and those to gentamicin, tobramycin, piperacillin and cefazolin were higher than 90%; both ESBLs-ECO production and non-ESBLs-ECO production were sensitive to Imipenem and Amikacin, with a
