Abstract: To explore and to analyse the application of non-pain bronchofibroscopy to the diagnosis and treatment of pediatric pulmonary disorders difficult to diagnose. MethodsUnder general anesthesia of propofol,Olympus BF3c-20 bronchoscopy was used for pathogenesic examination and/or treatment of 92 cases from 2 months old to 15 years old with atelectasis of unknown origin,recurrent or prolonged wheezing and chronic cough. ResultsIn 38 cases with atelectasis,18 cases were found with inflammatory narrowness and stenosis(47.4%).After bronchoalveolar lavage and administration of drugs by bronchoscopy，29 cases were cured in 38 cases(76.3%).In 25 cases of recurrent and prolonged wheezing,14 cases were found with stenosis and mucus clog,9 cases with tracheobronchial softness,stenosis,2 cases with tiny foreign body.Optimal effect was acquired after bronchoalveolar lavage and administration of drug.In 29 cases of chronic cough,4 cases were caused by foreign body,19 cases by chronic endobronchialitis.92 cases were anesthesed through propofol and blood satuation was maintained over 90%. ConclusionNon-pain bronchofibroscopy is very important in pathogenesis diagnosis and treatment for atelectasis,recurrent or prolonged wheezing and chronic cough.And it has featured value in diagnosis for tiny foreign body.Bronchofibroscopy through non-pain propofol general anesthesia is a technique easy to perform,with decreased impair risk and with increased safety.
