摘要
目的了解铜绿假单胞菌的临床分布及耐药性特性。方法对医院2007年7月至2008年10月细菌培养和药敏试验的结果进行回顾性分析。结果共分离铜绿假单胞菌335株,占总病原菌9.2%;主要标本来源是痰液,占77.6%。高发病区是ICU病房。铜绿假单胞菌对丁胺卡那霉素、哌拉西林/他唑巴坦、妥布霉素、左氧氟沙星、头孢吡肟、庆大霉素、替卡西林及环丙沙星12种常用抗菌药物耐药率小于10%。对亚胺培南不敏感的铜绿假单胞菌对氨曲南、头孢他啶、环丙沙星、左氧氟沙星、哌拉西林/他唑巴坦的耐药率明显高于对亚胺培南敏感的铜绿假单胞菌(P<0.05)。结论铜绿假单胞菌多重耐药现象普遍存在,建议治疗选用丁胺卡那霉素、哌拉西林/他唑巴坦、妥布霉素。
Objective To investigate the clinical distribution and the drug resistance characteristics of Pseudomonas aeruginosa . Methods The results of the bacterial culture and the antimicrobial susceptibility test in the hospital from July 2007 to October 2008 were performed the retrospective analysis.Results Totally 335 strains of Pseudomonas aeruginosa were isolated,accounting for 9.2% of isolated pathogenic bacteria.The main specimen source was sputum,accounting for 77.6%.The ICU ward was the high incidence area.The resistance rates of Pseudomonas aeruginosa to amikacin,piperacillin/tazobactam,tobramycin,levofloxacin, cefepime,gentamicin,ticarcillin and ciprofloxacin were less than 10%.The resistance rates of imipenem-insensitive Pseudomonas aeruginosa to aztreonam,ceftazidime,ciprofloxacin,levofloxacin,piperacillin/tazobzctam were significantly higher than those in imi-penem-sensitive Pseudomonas aeruginosa （P〈0.05）.Conclusion The multiple drug resistance phenomena of Pseudomonas aerugi-nosa generally exist,amikacin,piperacillin/tazobactam and tobramycin are recommended for the treatment of infections caused by Pseudomonas aeruginosa .
