RESUMO
Objective To analyze the clinical distribution and antimicrobial resistance of Pseudomonas aeruginosa (PA) so as to guide the reasonable clinical use of antibiotics .Methods The results of drug susceptibility testing of PA strains isolated from pa‐tients in the Hongqiao Hospital from Jan .2010 to Dec .2013 and distribution of specimens were retrospectively analyzed .The WHO‐NET5 .5 software was used for data statistic analysis .Results A total of 752 PA strains were isolated and were most isolated from sputum(accounted for 86 .8% ) ,followed with secretions(accounted for 5 .7% ) .The drug resistance rates of PA to imipenem ,mero‐penem and cefoperazone‐sulbactam were 1 .6% ,2 .9% and 1 .9% ,respectively ;while the drug resistance rates to ciprofloxacin ,levo‐floxacin ,amikacin ,gentamicin ,tobramycin ,cefepime and piperacillin‐tazobactam were 11 .3% ,12 .5% ,14 .0% ,16 .5% ,15 .0% , 11 .6% and 14 .1% ,respectively ;the drug resistance rates to other antibiotics were higher than 20 .0% .The drug resistance rate to sulfamethoxazole‐trimethoprim was the highest(81 .4% ) .Conclusion PA may mainly induce respiratory tract infections ,and the drug resistance rates of PA to the commonly used antibiotics are relatively low .The clinicians should reasonably use antibiotics so as to reduce the resistant strains .
