Abstract:
OBJECTIVE To investigate the prevailing strains of pathogens of hospital acquired infections in ICU and their drug-resistances in order to provide treatment basis for critical and severe patients in fighting against infection.METHODS A retrospective investigation analysis was made for all the isolated bacteria as well as their drug-resistance in our hospital from Jan 2000 to Dec 2005.RESULTS Totally 869 bacterial strains were isolated which included 666 strains of G-bacteria(74.3%),and 230 strains of G+bacteria(25.7%).The G-bacteria included Pseudomonas aeruginosa,Klebsiella pneumoniase,Escherichia coli,Acinetobacter baumannii,etc,which were isolated mainly from respiratory tract.The G+ bacteria consisted of Staphylococcus and Enterococcus.Staphylococcus were mainly isolated from respiratory tract and Enterococcus from urinary tract.Bacteria were highly resistant to commonly used antimicrobials and demonstrated multi-drug resistance.The isolated rate of G+bacteria and drug resistance of G-bacteria to the commonly used antibiotics was increasing yearly.CONCLUSIONS The pathogens are mainly isolated from respiratory tract and the most are G-strains and multi-drug-resistant.The selection and use of antibiotics should be based on the results of drug-sensitivity tests.
