Analysis on distribution characteristics and drug resistance of pathogenic bacteria in ICU / 国际检验医学杂志

ABSTRACT

Objective To investigate the distribution characteristics and drug resistance of pathogenic bacteria in ICU . Methods The bacteria identification and drug sensitive test were carried out on all pathogenic bacteria in ICU of our hospital from January 2013 to December 2013 .Results A total of 187 strains of pathogenic bacteria were separated ,among them 37 strains (19 .79% ) were Gram‐positive bacteria ,which was dominated by staphylococcus aureus ,with drug resistance rate to vancomycin , teicoplanin and linezolid of 0 .00% ;135 strains were Gram‐negative bacteria (72 .19% ) ,which was dominated by pseudomonas aeruginosa ,acinetobacter baumannii ,klebsiella pneumoniae and escherichia coli ,the drug resistant rate of acinetobacter baumannii to cefoperazone/sulbactam and minocycline was lower (43 .59% ,46 .15% ,which of pseudomonas aeruginosa to amikacin ,cefotaxime , cefoperazone/sulbactam were 27 .91% ,32 .56% and 30 .23% ,respectively ;15 strains(8 .02% ) of fungi were isolated ,which were mainly candida albicans and candida tropicalis .Conclusion Regular detection of distribution types and drug resistance change can provide the basis for climical rational use of antibacterial drugs .
