Pediatric asthma is a common pediatric respiratory disease. Pediatric asthma is divided into acute exacerbation, remission and recovery periods. The characteristics of the attack are different in different periods, so the treatment plan is different. Once a clear diagnosis of asthma is made it is necessary to go to a regular hospital for standardized, long-term, reasonable and personalized treatment and choose a specific treatment plan according to the child’s condition. Specific treatments include the following: during the acute exacerbation of asthma, nebulized inhaled bronchodilators, commonly used as terbutaline or salbutamol, are needed to relax the airways, improve ventilation and relieve the symptoms of hypoxia, while systemic glucocorticoid drugs should be applied to control inflammation. After the above treatment reaches the remission stage, the systemic glucocorticoid is replaced by inhalation hormone therapy, and budesonide aerosol can be chosen, which can directly reach the lesion site with rapid onset of action and less side effects. The duration of this phase is longer, usually at least six months, and the lung function and allergens should be reviewed regularly during the whole period of medication. The recovery period is usually possible with the above mentioned active treatment. Pediatric asthma indicates that the child has airway hyperresponsiveness. Once pediatric asthma is clearly diagnosed, long-term inhaled glucocorticoids are the key to treating asthma. Topical inhaled medications have few adverse effects and will not affect the child’s growth and development, which parents need not worry too much about.
