Intensive care unit separation of bacteria drug resistance surveillance / 中国基层医药

ABSTRACT

Objective To understand the hospital intensive care unit(ICU) pathogenic bacteria distribution and drug resistance for providing the basis for rational drug use and hospital infection control and prevention.Methods The drug resistance of 749 strains of pathogenic bacteria the separated from ICU was analyzed from January 2009 to December 2012.VITEK 2 Compact automatic bacteria identification instrument was used to detect bacteria identification and drug sensitive test using.Results There were Acinetobacter baumannii(208 strains,27.8％),Pseudomonas aeruginosa(108 strains,14.4％),E.coli (96 strains,12.8 ％),Staphylococcus aureus (76 strains,10.1％),Klebsiella pneumoniae(62 strains,8.3％) mainly accupied in 749 strains of pathogenic bacteria.The species was mainly from sputum specimens sources (503 strains,67.2％) ; the separation rate of Methicillin-resistant staphylococcus aureus (MRSA) was 82.9％ (63/76) ; the separation rate of Imine resistance from South pseudomonas aeruginosa(IRPA) was 22.2％ (24/108) ; the separation rate of resistance to carbon penicillium alkene antimicrobial acinetobacter baumannii (CR-AB) was 88.0％ (183/208).The resistant rate of Acinetobacter baumannii to amikacin was from 28.6％ to 31.5％,the other 20 kinds of antimicrobial drug resistant rate was as high as 81.6％-100.0％ ; Pseudomonas aeruginosa to ciprofloxacin,ofloxacin,aztreonam and piperacillin/tazobactam resistant rate of 11.6％-25.0％.Conclusion Detection of pathogens in ICU,multi-drug resistance is serious,the hospital should strengthen the bacterial drug resistance monitoring,rational use of antimicrobial drugs,reduce the nosocomial infection.
