Bronchopneumonia is a common infectious disease of the respiratory system in children, especially infants and young children. In the process of treatment, we often choose nebulized inhalation therapy, because nebulized inhalation therapy, can have anti-inflammatory and reduce airway spasm on the airway localization, which can improve the patient’s symptoms of coughing and shortness of breath. Commonly used drugs for nebulized inhalation include budesonide suspension, terbutaline nebulized solution, and compound ipratropium bromide solution. Due to the relatively small molecular particles, these drugs can act directly on the airway localization, and can also facilitate the absorption of the airway mucosa, which has a better effect on improving the symptoms of patients. However, after nebulized inhalation, the nebulized tube must be cleaned and the mouth must be rinsed to prevent the formation of oral fungi.
