Objective:
To investigate the common causes of recurrent wheezing in young children.
Methods:
Electronic bronchoscopy was performed on 67 children with recurrent wheezing or who did not respond to the conventional treatment.
Results:
The electronic bronchoscopy showed intimitis in trachea and bronchi in 19 cases, intimitis and inflammatory stricture in 11 cases, foreign bodies in the bronchi in 11 cases, trachea and bronchus softening in 19 cases, and bronchopulmonary dysplasia in 3 cases. The other 4 cases presented endometrial tuberculosis, epiglottic cyst, laryngeal papilloma or compression outside trachea (thymus) under the electronic bronchoscope.
Conclusions:
In addition to inflammation, trachea and bronchus softening as well as foreign bodies in the bronchi are also the common causes in children with recurrent wheezing or who do not respond to the conventional treatment. Electronic bronchoscopy appears to be an effective way to determine the cause in these children.
