If the patient has one of the symptoms such as recurrent wheezing, coughing, shortness of breath, chest tightness, etc., and at the same time a positive bronchial provocation test, then it can assist in the diagnosis of bronchial asthma, and bronchial asthma treatment is needed, which includes the three aspects of preventive treatment, controlling the disease and relieving the symptoms. 1. Preventive treatment: mainly refers to avoid triggering the disease by identifying and reducing the exposure to risk factors, such as finding the allergens or other non-specific triggers that cause asthma attacks, so that the patient can get rid of and avoid the exposure to these risk factors for a long period of time, which is the most effective way to prevent and treat asthma. 2. Disease control: mainly used for the treatment of chronic inflammation of the airways to maintain clinical control of asthma, the need for long-term use of anti-inflammatory drugs, commonly used drugs, including inhaled glucocorticosteroids combined with long-acting adrenergic agonists, such as budesonide formoterol, leukotriene modifiers, such as montelukast, and so on. 3. Symptom relief: mainly used to relieve the symptoms of dyspnea and wheezing during acute asthma attacks, commonly used drugs include short-acting β2 agonists such as terbutaline, short-acting inhaled anticholinergic drugs such as ipratropium bromide, short-acting theophylline such as aminophylline, systemic glucocorticosteroids such as methylprednisolone, etc. Positive bronchial provocation test may be helpful for the relief of symptoms. A positive bronchial provocation test can assist in the diagnosis of asthma, but a positive bronchial test alone does not completely confirm the diagnosis of asthma. False positives may occur due to respiratory infections, smoking, or high sensitivity to provocative medications, which can lead to constriction of the airways. Therefore, it is necessary to make a comprehensive judgment according to the patient’s own situation, and give reasonable treatment under the guidance of the doctor.
