Abstract:
OBJECTIVE To investigate flora distribution and drug resistance status of nosocomial infections with Pseudomonas aeruginosa (PAE) in intensive care unit (ICU) and to provide the scientific reference for clinically reasonable use of antibiotics. METHODS PAE was isolated,cultured and identified according to the National Clinical Laboratory Operation Rules. The antibiotic susceptibility test was performed by K-B method and the results were read according to CLSI 2004-2006. RESULTS Among 254 PAE strains,the isolating rate in the lower respiratory tract samples was the highest (rriving 59.4%). Then the isolating rate in the wound and soft tissue infection samples was 13.8%. The drug-resistance supervision in vitro accounted for 17.3% and 19.7%,respectively,of PAE were resistant to imipenem and meropenem in ICU. The drug resistance rate to aztreonam,trimethoprim-sulfamethoxazole,ciprofloxacin,levofloxacin,gentamicin,cefotaxime,cefepime and piperacillin was all over 60.0%. CONCLUSIONS PAE in ICU is the mostly multi-resistant strain. We should strengthen its monitoring and controlling.
