Abstract:
OBJECTIVE To sum up the distribution and drug-resistance of pathogens in hospital-acquired pneumonia(HAP) at each stage,and then to offer references for treatments of HAP.METHODS To retrospectively analyze 46 patients whose course was over 30 day and who were in hospital from Jan 2000 to Oct 2005,and to divide course into prophase,metaphase and anaphase,and then to clinically study the drug-resistance and distribution of pathogens in each phase.RESULTS In prophase the most pathogens were Gram-negative bacilli(accounted for 87.5%),in metaphase the Gram-positive cocci were manifold distinctly;and in metaphase and anaphase drug-resistance of Gram-negative bacilli increased distinctly;and the fungi were not detected in prophase,but were positive in metaphase and anaphase.CONCLUSIONS In prophase application of third generation cephalosporin which is more sensitive to Gram-negative bacilli as an empirical antibacterial therapy is right;based on the drug-resistance and distribution of pathogens,the antibacterial drugs and treatment must be readjusted.
