ICU, the Fourth Hospital of Hebei Medical University, Shijiazhuang 050011, China ABSTRACT Objective: To investigate the distribution and drug resistance status of pathogens in intensive care unit of our hospital and then to offer prevention and treatment basis for clinical medication. Methods: A total of 182 strains of pathogens isolated from 274 patients from January to December in 2004 were analyzed. Results: Of 182 strains, including 137 Gram-negative bacilli strains, 5 Gram-positive cocci strains and 40 fungi strains, most from lower respiratory tract, the Gram-negative bacilli were dominated. Among the Gram- negative bacilli, the leading 5 strains were Acinetobacter baumannii, Pseudomonas aeruginosa, Escherichia coli, Ctenotrophomonas maltophilia and Klebsiella pneumoniae. 19 Escherichia coli and Pseudomonas aeruginosa strains, 78.95% of which produced ESBLs. Gram-negative bacilli were more sensitive to imipenem than others, and most of which were multi-resistant. Conclusion: Most pathogens are highly resistant to drugs. It is very important to use antibiotics reasonably and monitor drug-resistance progressively for conducting clinical medication.
