Abstract:
Objective:To search for pathogen distribution of hospital-acquired pneumonia and their sensitivity to antibiotics.Methods:156 strains were isolated from 557 in patients in respiratory department and intensive care units from 2002 to 2004 of our hospital,and the sensitivity rates to antibiotics were analyzed by drug sensitivity test.Results:Of the 156 strains,66.03% were Gram-negative bacilli,with 20.51% as Pseudomonas aeruginosa,11.54% Encherichia coli,and 9.62% Klebsiella pneumonia,and the sensitivity rates of the 6 species of Gram-negative bacilli to imipenem were high;27.56% were Gram-positive cocci,were 15.38% as Staphylococus Aureus,and 8.97% Streptococcus pneumoniae,which were sensitive to vancomycin;10.7% were Fungi(8 strains of Candida albicans).Conclusions:The main isolated pathogens from HAP patients were Gram-negative bacilli,and the sensitive rate of which to imipenem was the highest,to cefoperazone-sulbactam was the second,and 6.41% of the HAP patients accompanied fungus infection.
