Patients with bronchiectasis generally do not have a fever. However, if there is an acute exacerbation of bronchiectasis or if there is an additional infection, they might develop a fever. In cases where patients with bronchiectasis exhibit a fever, it generally indicates an infection or that their condition may be more severe compared to those without a fever. Under such circumstances, anti-infection treatment might be required. Moreover, the duration of the fever and its maximum intensity can reflect the severity of the infection to a certain extent.

How to check for bronchiectasis?

How to check for bronchiectasis: generally, corresponding physical examinations and laboratory tests are used for diagnosis. Early physical examinations may not show positive signs. When the condition is severe or secondary bacterial infection occurs, fixed and persistent moist rales can be heard in the affected areas. Some patients may show signs of oxygen deficiency, such as clubbing and cyanosis. During acute infections, routine blood tests will show increased white blood cell counts and neutrophil counts. Sputum examination may reveal elastic fibers and pus cells. A chest X-ray can show thickened and disordered lung periphery, and typical lesions may appear as honeycomb-like curly shadows.

Can bronchiectasis be treated with nebulization?

Patients with bronchiectasis can undergo nebulized inhalation, and nebulized inhalation has a very good therapeutic effect for the treatment of bronchiectasis. Commonly used nebulized medications include budesonide suspension and terbutaline nebulizer solution, among others. These medications work to dilate the bronchi and relieve airway spasms. For patients with excessive phlegm, these treatments can promote expectoration. They are also very effective for patients with bronchiectasis-caused breathing difficulties. Furthermore, there is now literature proving that inhaling budesonide suspension has a good anti-inflammatory effect on lower respiratory tract infections and helps in the absorption of inflammation.

How to cure bronchiectasis?

Bronchiectasis is caused by chronic suppurative inflammation and fibrosis of the bronchi and the surrounding lung tissue, damaging the muscles and elastic tissues of the bronchial walls, leading to deformation and permanent dilation of the bronchi. Bronchiectasis is chronic in formation, thus once diagnosed, it is incurable. Prevention is very important. The main cause of recurrent episodes of bronchiectasis is infection, so preventing infections is crucial. It is advised to consume a high-quality protein diet, participate in appropriate physical activities, and get annual vaccinations for influenza and pneumonia to prevent infections.

Bronchiectasis is what?

The basic cause of bronchiectasis is due to infection of the bronchi and lung tissue, as well as bronchial blockage. Infections can cause blockages, and blockages can also lead to infections. The two influence each other, promoting the occurrence and development of bronchiectasis. This results in damage to the bronchial walls and leads to a large amount of purulent sputum, mainly due to an increase in secretions. Additionally, chronic infection or fibrosis of the lung tissue can also lead to bronchial dilation, causing the bronchial walls to dilate and become congested.

How is bronchiectasis treated?

The treatment of bronchiectasis mainly includes medical treatment and surgical treatment. Medical treatment primarily aims to control infection and promote the drainage of sputum. Antibiotics are crucial for controlling infections, initially based on empirical therapy. Adjustments can be made accordingly if results from sputum culture and drug sensitivity tests are available. Secondly, to promote sputum drainage, we can use postural drainage or mechanical vibration to expel sputum. Expectorant medications such as ambroxol and bromhexine, or nebulized inhalation therapy may also be utilized. Thirdly, bronchodilators can be used to relieve asthma symptoms and ease the patient's discomfort. If the patient has hemoptysis, hemostatic treatment should be provided. Surgical treatment is primarily considered for patients with localized bronchiectasis and when medical treatment is ineffective, in which case surgical resection may be considered.
