Asthma is a common pediatric disease, and asthma in two-year-olds is a respiratory hyperresponsive disease caused mainly by allergies, often manifesting as sudden onset breathing difficulties. At this time, the child needs to go to the hospital for formal consultation and respiratory function testing, and the doctor needs to evaluate asthma, mainly to assess the severity of asthma and the frequency of attacks. After the child is diagnosed with asthma, standardized treatment is needed, as follows: 1. Standardized inhalation of glucocorticoids and bronchodilators; 2. Glucocorticoid treatment is mainly to reduce the inflammatory response in the lungs, and bronchodilators are mainly to relieve bronchospasm and asthma symptoms. Asthma treatment lies in standardized and long-term persistent treatment. Parents often have a misconception that asthma is an acute disease, which is a wrong idea. Asthma is a serious disease during the usual attacks, but the pathological basis exists when it is not, it just does not manifest itself. Many parents mistakenly believe that their child is not sick, which is actually a misconception, so it often affects their child’s treatment. In this case, parents stop nebulized inhalation and lose the opportunity to control the long-term inflammation of asthma.
