ABSTRACT
OBJECTIVE To understand the application value of protective specimen brush(PSB)in severe pneumonias.METHODS Fifty seven cases diagnosed as severe pneumonia were admitted into the group.The specimens were sampled via the fiberoptic bronchoscope(FOB)and the PSB and then were done bacteria quantitative culture(QC).According to these,we adjusted antibiotics.RESULTS With the PSB and bacteria QC technologies,45 strains were detected in 57 cases,with a positive rate of 78.95%.In the progress of operating FOB-PSB examination,patients life signs didn't change significantly.FOB-PSB's sensitivity and specificity were about 97.73% and 84.62%,respectively.The therapy efficiency rate was 91.23%.CONCLUSIONS It is a good choice to use the PSB for sampling in severe pneumonia via fiberoptic bronchoscope.
