Scanning Microscopic Observation of Bronchial Mucosa Before and After Bronchoalveolar Lavage in Children with Acute Lower Respiratory Tract Infection

Abstract

In recent years, the incidence of acute lower respiratory tract infections in children has gradually increased, seriously threatening children's lives and health. The emergence of bronchoalveolar perfusion therapy has brought good news and achieved good results. Therefore, it is very necessary to actively carry out scanning microscopy observation research on bronchoalveolar lavage based on bronchoalveolar lavage to treat children with acute lower respiratory tract infection. The purpose of this article is to investigate the bronchoalveolar lavage in the treatment of children with acute lower respiratory tract infection before and after bronchial mucosa scanning microscopy, a retrospective study of 120 children with acute lower respiratory tract infection, according to whether bronchoalveolar lavage is divided into control groups cases and 60 cases in the lavage group to observe changes in mucosal area and secretion content, respectively. The results of the study showed that the number of children with a bronchial mucosal surface reduction of more than 30% before and after surgery in the lavage group and the control group were 24 and 6, respectively, and the proportions were 40% and 10%, respectively. The number of children whose bronchial mucosal surface decreased by more than 0-30% before and after surgery in the lavage group and the control group were 27 and 31, respectively, and the proportions were 45% and 52%, respectively. It can be seen that the scanning microscope is important for the observation of bronchial mucosa before and after bronchoalveolar lavage treatment of children with acute lower respiratory tract infection.
