[摘要]目的 探讨院内获得性绿脓杆菌感染特点及目前常用多种抗生素的耐药性。方法 收集2009年10月~2011年5月呼吸内科合并肺绿脓杆菌感染病例117例(其中47例气管插管或气管切开接受机械通气)痰培养标本,应用微生物自动分析仪对绿脓杆菌共457株进行鉴定及药物敏感试验。结果 引起院内获得性绿脓杆菌感染的457株绿脓杆菌对13种常用抗生素的平均耐药率>30%,对阿米卡星耐药率<30%,对喹喏酮类耐药率接近30%,对β-内酰胺类和头孢菌素类抗生素耐药率较高。结论 治疗院内获得性绿脓杆菌感染,β-内酰胺酶类联合氨基糖甙类或喹诺酮类为较优化的组合;对MDR-PA可首选头孢哌酮舒巴坦与阿米卡星联合或头孢哌酮舒巴坦与环丙沙星联合。

[Abstract] Objective To conduct clinical analysis of in-hospital acquired Pseudomonas aeruginosa infection and study multiple its drug resistance to antibiotics. Methods Collected 117 cases (of which 47 tracheal intubation or receiving mechanical ventilation) with Pseudomonas aeruginosa infection between October 2009 to May 2011. Cultivated sputum specimen ,identified and performed drug sensitive test to 457 strains of Pseudomonas aeruginosa with microorganism analyzer. Results Four hundred ane fifty-seven strains of Pseudomonas aeruginosa that cause in- hospital acquired infection of Pseudomonas aeruginosa to 13 kinds of common antibiotics resistance rate on average>30%, amikacin resistance rate<30%, on chloroquine ketones resistance was close to 30% for beta-lactam and cephalosporin class antibiotics resistance rate was higher. Conclusion The treatment of in-hospital acquired infection of Pseudomonas aeruginosa, β-lactamase United aminoglycoside or quinolone classes are optimized combination; MDR-PA preferred cefoperazone sodium and sulbactam sodium combined with amikacin or ciprofloxacin cefoperazone and sulbactam.

绿脓杆菌,也称铜绿假单胞杆菌(Pseudomonas aeruginosa,PA),广泛分布于自然界及正常人皮肤、肠道和呼吸道,是临床上较常见的条件致病菌之一。在重症监护病房,绿脓杆菌(PA)在生物体的肺、血液、泌尿道、手术部位及软组织感染[1]中位居前五位。其中呼吸道感染最常见,占绿脓杆菌感染的52%。绿脓杆菌血症占全部菌血症的2.7%,所致死亡率在过去的几十年中居高不下,大多数研究发现其死亡率为33%~61%[2,3]。合并院内获得性绿脓杆菌感染在临床呼吸内科最为常见,随着抗生素的大量广泛应用,绿脓杆菌的耐药性不断升高。为合理选择抗生素,本文对13种常用治疗绿脓杆菌感染的抗生素做了研究分析,现报道如下。

1.1 一般资料
收集中国医科大学第一附属医院呼吸内科及沈阳维康医院呼吸科2009年10月~2011年5月合并绿脓杆菌感染患者117例,取其清晨深咯痰标本,按常规方法培养、分离、鉴定,获得纯菌后采用Vitek微生物自动分析仪鉴定到种,20个月内共分离获得457株绿脓杆菌 ......
