Parents must realize that asthma is a chronic lung disease that cannot be cured, but can be completely controlled with standard treatment in a regular hospital. Do not blindly believe the promises of curing asthma as depicted in leaflets or false advertisements. There are countless examples of those who missed the timing of treatment or refused to apply glucocorticosteroids due to misconceptions about inhaled glucocorticosteroids, resulting in poor disease control and no medication available at a later stage. Prevention and treatment of asthma in children should be done in the following three ways: 1. Avoid exposure to and stay away from asthma triggers. Some of the more common asthma triggers are: dogs, cats or other animals; colds or flu; pollen from trees, grasses and weeds; dust; mites or molds; perfumes, paints, sprays or other strong smells; smoke from cigarettes, burning wood and paper; weather changes or very cold air; air pollution; crying, laughing or shouting; aspirin or other drugs; certain foods; etc. Parents and Patients should check which of the above will trigger asthma symptoms and avoid exposure or stay away or control them once identified for prevention purposes. 2. Use medications to make breathing easier and to control non-infectious inflammation of the airways. The former can be used for bronchodilator class of drugs, such as terbutaline sulfate, albuterol, albuterol, albuterol, albuterol, aminophylline, long-acting theophylline, etc.; the latter for anti-non-infectious inflammatory drugs, such as co-corticosterone aerosol and dry powder co-corticosterone, inhalation glucocorticoids such as sulforaphane. As well as inhalation and oral two doses of sodium cromoglycate, etc. 3.In addition, anti-allergic drugs such as ketotifen and loratadine are often applied in the treatment. The role of leukotriene receptor antagonist montelukast sodium is also valued and used in clinical practice. As well as the application of some immunomodulators such as thymidine, etc.
