OBJECTIVE To learn the profile of Gram-negative bacilli in ICU ward during the eight years and analyze the drug resistant rates in order to provide the basis for empirical treatment of infection. METHODS The bacteria were identified by VITEK-2 and API system. Antibiotic sensitivity test adopted Kirby-Bauer method. Data were analyzed by WHONET5.4 software. RESULTS Totally 1492 strains of Gram-negative bacilli were isolated from ICU ward, which included 1146 strains of non-fermentaters, accounted for 76. 8% and 346 strains of Enterobacteriaceae, accounted for 23.2 %. The first five bacteria were Pseudomonas aeruginosa, Burkholderia cepacia, Acinetobacter baumannii, Stenotrophomonas maltophilia, and Escherichia coli by turns. The drug resistant rates were higher and had the tendency of increase by years. CONCLUSIONS Non-fermentaters are the main organisms in ICU ward. The species of bacteria are diversified and the drug resistant rates of them are serious, which should be monitored not only because helping clinical therapy but also discovering the prevalence of drug resistant strains. |
