Abstract:
OBJECTIVE To study the alteration of microbial population distribution in intensive care unit (ICU) for the reference to clinical drug administration. METHODS The distributed features of 413 strains of infection germs detected among the patients of ICU were statistically analyzed during the years of 2002 to 2005. RESULTS The main germs of 413 strains were Pseudomonas aeruginosa(87 strains), Acinetobacter baumannii(48 strains), Stenotrophomonas maltophilia(34 strains), Staphylococcus epidermidis(30 strains), S. aureus (20 strains) and Escherichia coli (19 strains). The first 3 species were P. aeruginosa (21.07%), A. baumannii(11.62%) and Sten. maltophilia (8.23%). CONCLUSIONS Most pathogens in ICU are Gram-negative bacteria and the proportion of Sten. maltophilia increases gradually. It is a very important clinical value to inspect the bacterial distribution and antibiotics should be used rationally.
