Abstract:
Objective To analysis the risk factors and drug resistance of multidrug-resistant pseudomonas aeruginosa(MDRP) infection and to provide the basis for clinical anti-infective therapy .Methods Predisposing factors and drug resistance to clinical commonly used antibacterial drugs of MDRP which were separated from September 2010 to December 2011 were adopted for retro-spective analysis .Results A total of 235 hospital MDRP infection were collected ,97 multidrug resistant strains were concluded ,the separation rate was 41 .2% .The separation rate of ICU and neurosurgery were higher ,account for 35 .54% and 22 .31% respective-ly .The main resource of specimen is respiratory tract ,about 75 .21% .The resistance of MDRP was very serious .The resistant rate of Amikacin was the lowest ,account for 37 .11% ,followed by piperacillin/tazobactam ,ceftazidime ,account for 47 .4% and 48 .45%respectively .The resistant rate of other antimicrobial agents were greater than 50% .Advanced age ,serious underlying diseases ,long hospital stay ,long-term repeated application of broad-spectrum antimicrobial drugs ,admission to ICU ,invasive treatment operations were the risk factors for MDRP resistance .Conclusion The resistance is very serious ,in order to reduce the generation and spread of drug-resistant strains ,the hospital infection control ,drug resistance monitoring ,rational use of antimicrobial drugs and prevention of cross-infections should be strengthened .
