Bronchiectasis is usually caused by repeated infections in the body’s lungs, and the common clinical manifestations include cough, sputum, and hemoptysis. Patients with severe bronchiectasis should take timely treatment. It is very important to clear respiratory secretions and control infection in patients with severe bronchiectasis. Usually, sputum expelling agents and nebulized inhalation are used to make the secretions in the respiratory tract dilute and facilitate the coughing up of sputum. Patients with severe bronchiectasis are usually treated with medications and intravenous fluids to control infection. Common drugs include azithromycin, cephalosporin, etc. For patients with severe bronchiectasis who have acute respiratory tract infections, recurrent lung infections, and hemoptysis, lobectomy is recommended. However, not all patients can undergo the surgery. Generally, patients who have emphysema, heart disease, old and weak, and whose medication is effective are not recommended to undergo the surgery because the respiratory function of the organism will be seriously damaged after removing the lobe of the lung. At the same time, patients with bronchiectasis must keep the air in the room clear during treatment, and pay more attention to their diet, avoiding spicy stimuli, smoking and drinking, and suggesting light foods that are good for the airways.
