Asthma is one of the most common chronic diseases worldwide and its prevalence is increasing, especially in children. Asthma is a chronic inflammatory disease of the airways, and this chronic inflammation is an allergic inflammation that is not effectively treated with antibiotics. Common risk factors include exposure to allergens such as house dust mites (in items such as bedding, carpets and textile covers or pads on furniture), furred animals, cockroaches, pollen and molds; occupational irritants; tobacco smoke; air pollution; respiratory infections (viruses); exercise, violent mood swings; chemical irritants and medications (e.g., aspirin and beta-blockers). The development of asthma has been shown to be familial. The severity of asthma can be classified as intermittent, persistent mild, moderate and severe. Severity varies widely among individuals, is not necessarily related to the frequency and persistence of symptoms, and varies across time for the same individual. Treatment options for asthma depend on its severity. Asthma attacks (or exacerbations) are episodic, but airway inflammation is long-lasting. Many patients must take daily medication to control symptoms, improve lung function and prevent attacks. Other medications may be needed to relieve acute symptoms such as wheezing, chest tightness, and cough. Asthma treatment requires a good partnership between the patient and the health care provider, which allows the patient to learn to control asthma under the guidance of the health care provider. Many Olympic athletes, famous leaders, celebrities and ordinary people have asthma and are living well. Asthma can be prevented. For infants with a family history of asthma or atopy, avoiding allergens such as passive smoking, house dust mites, cats and cockroaches may be beneficial in stopping asthma in its tracks. For adults, avoiding smoking or passive smoking and exposure to chemical sensitizers in the work environment may be beneficial. The incidence rate of asthma, self-healing rate and curable rate of pediatric asthma has increased significantly in recent years, and the incidence rate has reached 5% in five major cities in China in 1995, and is about 5% in Qingdao. Without scientific and standardized treatment, about 50% of children can develop into adults with asthma. Asthma is an allergic disease, and the most effective treatment drug is inhaled glucocorticoid, supplemented by cisplatin, aminophylline, meprobamate, etc. Inhaled glucocorticoids are commonly used in the form of pramipexole aerosol, pramipexole, sulforaphane, etc. What are the possible side effects of inhaled glucocorticosteroids in children with asthma? Inhaled glucocorticosteroids are topical drugs with the advantages of small dosage and high efficacy, but they can also produce certain side effects, the common side effects are: discomfort in the throat and frequent throat clearing action, hoarseness, thrush, etc. The incidence is about 3%. Will inhaled hormones affect my child’s growth and development? The latest data show that during high doses of inhaled glucocorticosteroids, the growth rate of a small number of children may be slightly affected, but overall growth is not affected after reducing to maintenance doses or stopping the medication. The key to achieving asthma control is to insist on long-term medication, especially when the asthma is in remission, i.e. when there are no coughing and wheezing symptoms, and never reduce the dose or stop the medication once the symptoms are under control.
