Abstract：Objective To investigate the significance of flexible bronchoscopy in children with respiratory diseases. Methods A retrospective analysis was performed for the clinical data of 80 children who were hospitalized due to respiratory diseases (including severe pneumonia, Mycoplasma pneumoniae pneumonia with atelectasis/lung consolidation/local emphysema, protracted pneumonia, coughing and wheezing of unknown cause, chronic cough of unknown cause, and laryngeal stridor) and who underwent flexible bronchoscopy/alveolar lavage. Results Bronchoscopy found that all the 80 children had endobronchial inflammation, among whom 28 children had severe airway obstruction by secretion. Twenty-four children had congenital airway dysplasia besides endobronchial inflammation, and three children had bronchial foreign bodies. In the children with coughing and wheezing of unknown cause and laryngeal stridor, some had congenital airway dysplasia or bronchial foreign bodies. Among the 27 children with Mycoplasma pneumoniae pneumonia, 26 had severe airway obstruction/embolization by secretion; 25 children (93%) underwent chest imaging again at 2 weeks after alveolar lavage, and the results showed complete or partial lung recruitment. Among the 80 children who underwent bronchoscopy, 3 had severe hypoxemia during surgery, 1 had epistaxis, 1 had minor bleeding during alveolar lavage, 3 had transient bronchospasm, and 5 had postoperative fever; these children were all improved after symptomatic treatment. Conclusions Flexible bronchoscopy is safe and reliable in children with respiratory diseases. Early alveolar lavage under a flexible bronchoscope is recommended for children with severe/refractory Mycoplasma pneumoniae pneumonia to improve prognosis. Flexible bronchoscopy is recommended for children with recurrent coughing and wheezing and persistent laryngeal stridor, in order to directly observe the throat and airway under an endoscope.
