The purpose of this study is to analyze the pathogenic spectrum of children’s pneumonia with pulmonary consolidation, and provide information for clinical empirical anti-infection treatment. From January 2019 to January 2020, the clinical data of hospitalized children with pneumonia diagnosed who underwent fiberoptic bronchoscopy in our center were retrospectively reviewed. By the reading of two senior pediatric infectious doctors, the data of pathogens detection result of bronchoalveolar lavage fluid (BALF) from children with pneumonia and/or pulmonary consolidation were analyzed. The diagnosis of lung consolidation was based on imaging evidence. 286 BALF samples from 286 children with mean age of 5.5 (5.8±3.1) years were detected. 195 cases (68.2%) with pulmonary consolidation. The positive detection rates of pathogens in all patients were 76.6% (219/286). The positive detection rates of patients with or without pulmonary consolidation were 77.9%(152/195)and 73.6%(67/91)respectively (P>0.05). Mycoplasma pneumoniae, adenovirus, rhinovirus, respiratory syncytial virus and parainfluenza virus type 3 were the top five detected pathogens. Mycoplasma pneumoniae got the highest positive rate 77.0%(127/165)in children of 5 years old and above. The detection rates of mycoplasma pneumoniae in patients with or without pulmonary consolidation were 67.2% (131/195) and 61.5% (56/91), respectively, (P>0.05). Mycoplasma pneumoniae, adenovirus, rhinovirus, respiratory syncytial virus and parainfluenza virus type 3 infection were the dominant etiology of children’s pneumonia in the target population. The pathogens detection rates were similar in patients with or without pulmonary consolidation.
