Abstract:
OBJECTIVE To investigate the site of nosocomial infection in ICU,distribution and resistance of bacteria in order to make the intervention strategy.METHODS Antimicrobial susceptibility of pathogenic bacteria isolated from nosocomial infection patients in ICU from Jul 2006 to Jul 2008 was performed by Kirby-Bauer method.RESULTS The main pathogens of nosocomial infection in ICU were Gram-negative organisms(48.09%),Gram-positives(38.93%),and fungi(12.98%).The most common pathogens were Staphylococcus aureus,Acinetobacter baumannii,Pseudomonas aeruginosa,fungi,and S.haemolyticus.All strains of S.aureus and S.haemolyticas were antimicrobial sensitive to vancomycin,teicoplanin and linezolid.All A.baumannii strains were antimicrobial sensitive to cefoperazone/sulbactam.They were resistant to other antimicrobial agents.CONCLUSIONS Gram-negative organisms are the main pathogenic bacteria of nosocomial infection in ICU,but the percentage of Gram-positives and fungi is increasing,S.aureus is the most main pathogenic bacterium of nosocomial infection in ICU.S.haemolyticus is also a main pathogenic bacterium.The pathogenic bacteria of nosocomial infection in ICU are highly resistant to the most antimicrobial agents.
