Nebulization in children with cough is not harmful and can have a good effect on coughing and phlegm. Because the cough nebulized drugs for children mainly include the following: first is a kind of nebulization due to saline, which can humidify the airway and can dilute the sputum, thus facilitating the relief of cough with phlegm. The second is the application of glucocorticoids in budesonide suspension for nebulization. In this case, because the nebulization is localized, the absorption of systemic glucocorticoids is very small and does not cause symptoms such as full moon face and buffalo back. Finally, nebulized medications for children are bronchodilators, such as terbutaline, which also briefly relieves bronchospasm and thus cough symptoms without causing discomfort in children.
