Diagnosis of variant asthma, how to treat variant asthma

Diagnosis of variant asthma: When encountering patients who only complain of long-term cough (more than 2 weeks), the possibility of asthma should be considered, and the diagnosis can be confirmed on the basis of excluding medical history, careful physical examination, and summarizing clinical features, combined with the following methods:

1. If the patient's FEVL or PEFR measured at the time of visit is less than 70% of the normal value, he can be inhaled bronchodilator, and then the above indicators can be retested, such as the improvement rate of FEVL and PEFR is 15%, and the disease can be diagnosed.

2. If the patient's FEV1 and PEFR are 70% normal predicted at the time of presentation, bronchial provocation test can be performed cautiously.

3. Measuring the diurnal change of PEFR within 24 hours for 3 consecutive days is a simple and effective screening method for diagnosing this type of bronchial asthma, and if the PEFR mutation rate is 20%, the disease can be diagnosed. Although measurement of lung function markers is an effective means of early detection of this type of asthma, some studies have found that the frequency of coughing day and night does not correlate with the degree of lung impairment.

4. Test**For suspicious patients, bronchodilators, including 2-receptor stimulants, theophylline, if the cough is significantly reduced or disappeared, the diagnosis of bronchial asthma can be supported; If the effect is not significant, prednisone can be switched, most cough asthma symptoms can be significantly relieved within 1 week, and a few patients need **2 weeks to see the effect.

5. Exclude other diseases that can cause chronic cough.

The ** of variant asthma is mainly the use of bronchodilators to dilate the spasmodic trachea, nebulized inhaled glucocorticoids for local non-characteristic anti-inflammatory, reduce congestion and edema in the trachea, and if necessary, intravenous glucocorticoids are required, and leukotriene antibody antagonists delay the damage of lung function. If asthma is caused by a bacterial infection of the respiratory tract, it is also necessary to take effective anti-infection in a timely manner**.

Try to use the drug regularly and avoid stopping or reducing the dose to prevent the occurrence of asthma. Variant asthma is mainly a chronic cough that occurs repeatedly, which is easy to be ignored, and it is recommended to have pulmonary function tests and allergen tests in time to identify them. Get as much rest as possible, avoid strenuous exercise, avoid contact with allergenic substances, and keep your airways open.

AFC**, the hospital focuses on hard work and pays attention to efficacy; With its real efficacy and patients' voices, it stands out among many peers.

Hello! Cough-variant asthma is a specific type of asthma that does not have typical asthma symptoms and signs, and can easily trigger or worsen cough when exposed to cold air, dust, oil smoke, etc., or a cold. The harm to the human body is relatively large, and in order to be effective, timely diagnosis is the key.

The method of diagnosis is as follows:

1.Cough persists or reverses for more than a month, often occurs at night or early in the morning, worsens after exercise, and has a lot of phlegm; 2.Laboratory tests or other tests show no obvious signs of infection or have been ineffective with long-term antibiotics**; 3.

Bronchodilators can reduce seizures; 4.If there is a personal history of allergies, that is, accompanied by eczema, urticaria, allergic rhinitis, etc., family allergies can also be found; 5.Asthma attacks induced by exercise, cold air, allergens or viruses; 6.

Asthma is seasonal, mostly in spring and autumn and reversed; 7.Chest x-ray shows normal or increased lung markings but no other organic changes. Good luck soon**!
