When patients develop bronchiectasis infection, it is important to actively control the degree of lower respiratory tract infection at an early stage, which can be treated with appropriate sensitive anti-infective drugs and enhanced support, symptomatic management, etc. Patients often need to select the appropriate sensitive anti-infective drugs for treatment based on sputum culture, as well as other pathogenic tests. In the case of bronchiectasis combined with bacterial infection, the course of antibiotics should be normalized and the sputum reduced significantly for one week before stopping or reducing the drug depending on the situation. Patients need to strengthen the support and symptomatic treatment while anti-infection, choose the appropriate expectorant according to the condition, keep the patient’s airway open, and cooperate with the necessary postural drainage, as well as nebulized inhalation and other symptomatic treatment. Some severe patients with wheezing symptoms can be treated with bronchodilators. In some patients with more severe bronchodilator infection, bronchoscopy can sometimes be used for aspiration. Some patients with bronchial dilatation and infection can be treated with symptomatic treatment such as hemostasis because of hemoptysis.
