RESUMO
OBJECTIVE To investigate the nosocomial status and drug resistance of imipenem-resistant Pseudomonas aeruginosa(IRPA) to provide the reference for doctor′s use of the antibiotics.METHODS Totally 178 strains of imipenem-resistant P.aeruginosa were identified by the routine methods.And drug sensitivity was determined by Kirby-Bauer method.RESULTS All strains of IRPA were mainly from departments of respiratory diseases,tumor and geriatrics,most of them were isolated from sputum(62.4%).The susceptibility test showed that 100.0% IRPA were resistant to imipenem.Drug resistance rates to piperacillin,cefotaxim,gentamicin,ciprofloxacin and SMZ-TMP were all over 50.0%.CONCLUSIONS The status of nosocomial infection caused by IRPA is very serious.To detect and control the infection is very important.
