Abstract: AIM: To study the distribution of infectived bactarial In ICU and analyze their drug resistant rates. METHODS: 228 specimens were cultivated, the identification of bacteria and drug susceptibility were tested in the positive specimens. RESULTS: 186 specimens including bacteria were detected from 228 (accounted for 81.6%), which 42 specimens including gram positive coccus(accounted for 18.4%), and 144 specimens including gram negative bacilli(accounted for 63.2%), the staphylococcus aereus was primary in gram positive coccus, the first three bacilli were acinetobacter, pseudomonas aeruginosa, klebsiella pneumonice in gram negative bacilli, the resistant rates of the gram positive bacterium to other drugs were more than 80% except perfectly susceptibility to vancomycin, the decreasing susceptibility order among gram negative bacilli was cefoperazone sulbactam, piperacillin tazobactam, Meropenem.The resistant rate of pseudomonas aeruginosa to ceftazidime was 31%, the resistant rates to other drugs were more than 60%. CONCLUSION: There is higher infected rate, more kinds of infected bactiria and more serious resistant rates to ICU patients, it is necessary to choose antibiotic reasonably according to the results of drug susceptibil.
