The choice of bronchial stenosis treatment is mainly based on the etiology, including congenital bronchial stenosis and acquired bronchial stenosis. Acquired bronchial stenosis is most commonly associated with an inflammatory response of the respiratory tract, such as with wheezing bronchitis and bronchial asthma. This is the time to choose to use bronchodilator drugs, such as budesonide, salbutamol, terbutaline, ipratropium bromide, etc. It can be administered by intravenous drip or nebulized inhalation, which can relax the bronchial smooth muscle and improve the degree of narrowing, while making the bronchial passages open, which can achieve the purpose of stopping cough and calming asthma. Antibiotics, such as penicillin and amoxicillin, should be used early for bacterial infections. For congenital bronchial stenosis, which belongs to the dysplasia of the bronchial tract, surgical expansion of the bronchus can be taken at this time to solve the narrowed state of the tract, which can improve the ventilation and air exchange function.
