Abstract:
Objective To analyze the distribution and antimicrobial resistance of pathogens from patients with hospital infection in intensive care unit(ICU),and to discuss the corresponding strategy of prevention and treatment. Methods Clinical data of 891 patients hospitalized in the ICU of our hospital between Jan 2002 and Dec 2005 were collected.All the specimens were analyzed for pathogen distribution and resistance to antibiotics. Results Of all the isolated 1 155 strains,Gram-negative(G-)bacteria were the most popular pathogen(57.84%),whereas Gram-positive(G+) bacteria and fungi accounted for 21.39% and 20.78%,respectively.Most G-bacteria were less sensitive to imipenem(0-10.16%),and Pseudomonas aeruginosa was least sesitive to amikacin(6.89%) and cefoperazone-sulbactam(33.97%).G+ bacteria were most sensitive to vancomycin.Most fungus were Candida albicans(42.92%) and yeast species(22.90%). Conclusion Epidemiological investigation of pathogens in ICU is of great importance to the rational use of anti-biotics and may help to reduce the emergence of resistant strains.
