Abstract
Objective To make etiological analysis of nasopharyngeal aspiration(NPA) and bronchialveolarlavage fluid ( BALF) in children with respiratory tract infection. Methods Collected NPA and BALF from 140 cases of children with acute respiratory tract infection in our hospital,and compared the differences of pathogenic examination rate in NPA and BALF.Compared the differences of pathogenic infection rate among different diseases,and the difference of the simple pathogens infection rate and the mixed pathogens infection rate in NPA and BALF. Results The bacterial detection rate in NPA was higher than that in BALF (17.14% vs 8.57%);The virus detection rate in NPAwas lower than that in BALF (6.43% vs 14. 29%);The rate of atypical pathogen examination in NPA was higher than that in BALF ( 84. 29% vs 69. 29%) (all P<0.05).The simple atypical pathogens infection ratein BALF was higher than that of mixed infection (50. 71% vs 18.57%),the simple atypical pathogens infection rate in NPA was higher than that of mixed infection (45% vs 12.86%) ,and the rate of bacterial,viral and atypical pathogens in pneumonia patients were higher than those in bronchitis and bronchiolitis patients ( all P<0.05) . Conclusion The detection rate of bacteria and viruses in NPA was higher than that in BALF,but the detection rate of atypical pathogens was lower than that of BALF,the detection rate of pathogens in pa￣tients with pneumonia was higher than that in patients with bronchitis and bronchiolitis.关键词
