Bronchiectasis is not chronic obstructive pulmonary disease. Bronchiectasis is a general term for a group of diseases in which suppurative inflammation of the bronchial tubes occurs repeatedly for various reasons, thereby destroying the structure of the bronchial wall and thickening the wall to cause persistent dilatation of the bronchial tubes. The main clinical manifestations are chronic cough, sputum and hemoptysis. Some patients with bronchiectasis can be combined with chronic obstructive pulmonary disease (COPD) due to obstructive ventilatory dysfunction. Bronchiectasis requires active treatment of the underlying disease and symptomatic therapy. In case of acute infection, sensitive antibiotics such as levofloxacin can be chosen; attention should be paid to clearing airway secretions, including physical expectoration and sputum chemotherapeutic drugs (acetylcysteine, aminoglutethimide, etc.). Patients with recurrent hemoptysis can be treated with adrenochrome tablets to stop bleeding, or surgically if necessary. Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory airway disease characterized by persistent airflow limitation. The corresponding clinical symptoms are mainly chronic cough, sputum, wheezing and shortness of breath after activity. Treatment of chronic obstructive pulmonary disease in the stable stage includes active smoking cessation and getting out of the environment of dust and irritating gases; bronchodilators, such as the anticholinergic drug tiotropium bromide, can be given as prescribed by the doctor. Acute exacerbation treatment should first determine the cause of acute exacerbation, such as bacterial infection, can be given levofloxacin, cefixime and other antibiotics active anti-infection treatment. In summary, bronchiectasis and chronic obstructive pulmonary disease are two different diseases, if the patient has repeated cough, cough and other symptoms, it is recommended to consult a doctor in time, to clarify the cause of the disease, standardized treatment under the guidance of the doctor.
