If there is no recurrent cough, sputum, hemoptysis and other symptoms after bronchiectasis surgery, long-term medication can be avoided; if there are still symptoms, symptomatic medication is needed. If the bronchiectasis is limited and the recovery is good after surgery to remove the diseased lung tissue, long-term medication is not necessary. If only part of the diseased tissue is removed during surgery, and some bronchiectasis remains in the lungs, the need for medication can be determined by the symptoms of coughing, sputum and hemoptysis. If cough, cough sputum more, and the sputum is not easy to cough out, can be given to ambroxol, bromhexine and so on, sputum; if the sputum volume suddenly increased, and the purulent component increases, can be given to anti-infective drugs such as amoxicillin and other treatments; if there is a small amount of hemoptysis, adrenal chromone tablets and other hemostasis. After the bronchial dilatation surgery, you need to standardize the treatment under the guidance of a professional doctor, so as not to delay the condition.
