摘要
目的了解我院铜绿假单胞菌的感染分布与耐药情况，为临床治疗提供依据。方法对住院患者送检样本中培养分离出的403株铜绿假单胞菌的感染分布与耐药情况进行分析。采用稀释法进行药物敏感试验，结果按美国临床实验室标准化研究所标准判定。结果铜绿假单胞菌主要来自痰标本（339株，84．1％），耐药率最高为头孢曲松（271株，67．2％），对亚胺培南的耐药率最低（61株15．1％），其次为哌拉西彬他唑巴坦（90株，22．3％），对其他11种抗菌药物的耐药率均较高。结论铜绿假单胞菌主要引起呼吸道感染，对现有多种抗菌药物耐药严重，提示临床医生必须对该菌所致感染予以高度重视，关注易感人群，加强对该菌的监测，合理使用抗菌药物，以提高疗效和减缓耐药菌株的产生。
Objective To investigate the clinical distribution and drug resistance of pseudomonas aeruginosa and to offer basis for the clinical therapeutics. Methods The infection distribution and drug resistance of 403 samples of pseudomonas aeruginosa that were isolated from various kinds of specimens from inpatients were analyzed. The drug sensitivity test was done by means of dilution, and the results were assessed with Clinical and Laboratory Standards Institute. Results The highest positive rate of pseudomortas aeruginosa was in sputum （84. 1% ）. The resistance rates to ceftriaxone was high（271 strain, 67. 2% ）, the resistance rates to imipenem was the lowest（ 61 strain, 15. 1% ） and piperacillin/tazobactam was 22. 3% （90/403）. Pseudornoncts aeruginosa were high resistant to other 11 tested antibiotics. Conclusions Pseudomonas aeruginosa is a common pathogen of respiratory tract infection, which has a high resistance rate to the current clinical antibacterial agents. Consequently, clinical doctors should consider the infection results from pseudornonas aeruginosa to increase the positive effect and reduce drug resistance rate.
