Bronchiectasis is often characterized by persistent or recurrent coughing, coughing up sputum or coughing up purulent sputum. The sputum is mucopurulent or purulent and may be yellow-green in color. In severe cases, dyspnea, wheezing and hemoptysis may occur. The treatment of bronchiectasis is as follows: 1. Anti-infection: If patients with bronchiectasis show signs of acute infection such as increased sputum volume and its purulent components, anti-infection drugs such as ceftriaxone sodium, cefotaxime, levofloxacin, moxifloxacin and so on need to be applied. 2. Improvement of airflow limitation: patients with obstructive ventilatory dysfunction can use long-acting β2 agonists such as salmeterol, long-acting anticholinergic drugs such as tiotropium bromide. 3. Expectorant: postural drainage can be used to elevate the position of the affected lung, drain the bronchial opening downward, so that the sputum flows into the large bronchial tubes and trachea, and is discharged by coughing. Expectorant drugs include Ambroxol, Bromhexine and so on. 4. Treatment of hemoptysis: Posterior pituitary hormone, phentolamine and other hemostatic drugs can be given. If the bleeding is large, interventional embolization can be considered. 5. Surgery: Surgical resection of the lung is the only way to cure bronchiectasis. If the bronchial dilatation is limited, and the patient is still stubborn and recurrent after adequate medical treatment, surgical resection of the diseased lung tissue can be considered. Lung transplantation may be considered in appropriate patients who are disabled despite all treatments. If you are diagnosed or suspected of having bronchiectasis, you need to actively seek medical attention and standardize your treatment under the guidance of your doctor to avoid delays.
