Abstract:
OBJECTIVE To probe the pathogen′s distribution of ventilator-associated pneumonia(VAP),in order to offer the evidence of clinical therapy,prevent the onset of VAP and apply the antibiotics reasonably.METHODS We applied the methods of etiology,microscopic identification,bacteria culturing etc on 74 mechanical ventilation patients,and analyzed the etiology of early-onset and late-onset VAP in contrast.RESULTS Totally 121 pathogens were cultivated altogether in all 74 VAP patients.In the 36 pathogens which were cultivated from 29 early-onset VAP patients,there were 66.67% of simple culture(24 patients,24 strains) and 33.33% of co-culture(5 patients,12 strains),and in the 85 pathogens which were cultivated from 45 late-onset VAP patients there were 17.64% of simple culture(15 patients,15 strains) and 82.35% of co-culture(30 patients,70 strains).The proportion of co-culture in the late-onset VAP patients was prominantly higher than that in the early-onset ones(?2=27.821,P
