Should I Take Antibiotics for a Cough?

Variant asthma (CVA) is a special type of asthma. Cough is the only or main clinical manifestation. There are no obvious symptoms or signs of wheezing and shortness of breath, but it has high airway responsiveness. Many people are due to continuous cough Or the recurrence of the cough will cause the cough to persist and eventually cause cough variant asthma. Therefore, the variant asthma seriously affects the normal life of the patient, causing the patient to have difficulty breathing.

Variant asthma (CVA) is a special type

Professionally, cough variant asthma recurs frequently in spring and autumn.The main causes are as follows:

1,

Mainly manifested as irritating dry cough, usually a severe cough, night cough is an important feature. Colds, cold air, dust, oil fume, etc. can easily induce or aggravate cough. Cough is usually a persistent dry cough, especially at night or early in the morning, with frequent and severe attacks, and many patients have itchy throat. It is often induced and exacerbated by colds, sports, and inhalation of cold air. It can also occur due to contact with pollen, dust, and certain foods.

Cough may be the main clinical manifestation of variant asthma. It is mainly a long-term refractory dry cough. It often inhales irritating odors (paint, gasoline, perfume, pollen, etc.), cold air, exposure to allergens, and vigorous exercise. And respiratory tract infections, some patients may develop asthma without any incentive. Variant asthma mostly occurs at night and in the early morning, with spring and autumn being the most common.

Most patients have been treated with antitussive, phlegm and antibiotics for a period of time before seeing the doctor. Most of them have little effect, and the use of glucocorticoids, bronchodilators, 2 receptor agonist drugs can show relief of symptoms, and patients with variant asthma Chest tightness and dyspnea may also occur.

1,

In the pediatric outpatient department of the hospital, I encountered some children who came for a cough every day. Parents reported that the child had been coughing for more than a month, and the cough was mostly at night or in the early morning. There was paroxysmal, no asthma and fever, chest X-ray Filming and

Ineffective conventional anti-cold and anti-infective treatments,

First, reduce smoking, it is best to quit

Smoking belongs to the category of indoor environmental pollution. Smoking in pregnant women will increase the risk of asthma in their future children. For children, if two or one of their parents smoke, the risk of asthma will also increase. Children are more prominent. Studies have also shown a positive correlation between the degree of exposure to cigarettes and the occurrence of asthma.

Second, maintain a good indoor environment

Infants and young children are most closely related to the indoor environment. They have to stay indoors for a long time, and the tightness of modern buildings (better closed doors and windows and lack of natural ventilation). New building materials and updates to interior furniture (including carpets, mattresses, and upholstered furniture) will expose infants and toddlers to long-term exposure to indoor environment allergens (particularly house dust mites) and chemically stimulating odors.

3. Keep away from harmful outdoor environment

There are large differences in the outdoor environment around the world. Visible pollution remains at a high level in some countries, while the level of visible pollution decreases, while invisible pollution (mostly from automobile exhaust) is increasing. . The level of nitric oxide in the atmosphere has increased over the past 10 years. Although nitric oxide itself does not directly increase the prevalence of asthma, its damage to the respiratory epithelium makes it easier for other antigens to enter the deep layers of the respiratory tract and the lungs.

Fourth, choose a good working environment

It has been proven that occupational asthma can be effectively avoided through primary prevention. The substances in the working environment of certain occupations can sensitize the airways or stimulate the airways to induce occupational asthma. If effective preventive measures can be taken in time, Avoidance can prevent the occurrence of occupational asthma. Studies have shown that patients with atopic qualities may have a significantly increased risk of occupational asthma if they are exposed to certain high molecular weight allergens in the work environment for a long time. As with smoking, some special occupations can increase the risk of asthma in atopic people. Therefore, primary prevention through appropriate occupational health measures is very important.
