Both in China and in western countries, the incidence of asthma is increasing year by year, and Hefei is no exception. The national epidemiological survey of childhood asthma led by the respiratory group of the Chinese Academy of Pediatrics, our data in Anhui is not yet finalized, but from the current situation, the incidence rate is definitely increasing and may be in the middle level of the country. Zhou Haoquan, Department of Pediatrics, Anhui Provincial Hospital But some parents of children, and even some pediatricians, do not pay enough attention to asthma, and the most popular view is: what is the fear of a child wheezing a little, it will be fine after 6 years old. Even if asthma is diagnosed and treated in the pediatric department, once the wheezing or cough is controlled, the medication is stopped on its own, for what seems to be an even stronger reason: how can hormones be used for a long time? The parents cannot be blamed for the above-mentioned situation; they are not professionals, which only shows that we medical professionals do not promote enough. Asthma has four major symptoms: wheezing, coughing, chest tightness and difficulty breathing. Not every child has these symptoms, he may have only one or a few of them, and they mostly come on at night, so if you sleep in a separate room from your child, you may not even notice them. These symptoms that manifest themselves are really just the tip of the iceberg; the main problem is airway inflammation. Airway inflammation causes airway hyperresponsiveness, which leads to symptoms. How can airway inflammation be controlled? Only with inhaled hormones (e.g., cozaquinone), and if the symptoms are severe, or in children over the age of four, a combination of hormones and long-acting bronchodilators (Symbicortol, sulforaphane). These drugs, which are the most basic drugs available for the treatment of asthma, are also the most effective ones. However, these drugs require a sufficient time course to bring inflammation under complete control. Asthma symptoms will be significantly controlled after about 2 weeks of inhalation hormone or compound use, but at this time airway inflammation still exists, and there is not even much improvement from before medication. Symptoms will appear quickly only when triggering factors are encountered, such as cold and flu, strenuous exercise, self-medication discontinuation, and allergen exposure, etc. Only with regular, regulated, and sufficient time of use according to the course of treatment can airway inflammation be significantly controlled, thus control the onset of symptoms. Recently, in the clinic, some parents of children who have been treated for a short period of time but whose symptoms are well controlled have asked whether the medication can be stopped.
