The side effects of nebulization are mainly manifested as bronchospasm, acute pulmonary edema, nausea, vomiting, and fungal infections brought about by long-term nebulized glucocorticoids. 1. Bronchospasm: the inhalation of a large number of nebulized drugs itself, the lungs, bronchial tubes is a foreign substance, easily triggered by a series of bronchial response, a strong contraction, resulting in bronchospasm, causing dyspnea, asthma aggravation. 2. Pulmonary edema: because the inhaled drug dose is large or lasts for a long time, a large amount of gas and atomized particles enter the alveoli, causing the collapse of the alveoli, thus causing pulmonary edema. 3. Nausea and vomiting: the gas from the muscle will produce direct stimulation to the stomach and diaphragm, leading to spasm of the diaphragm, thus causing nausea and vomiting. 4. Fungal infections: Fungal infections are caused by prolonged nebulization with glucocorticoids, etc. This is aggravated by the fact that many children do not rinse their mouths after nebulization. Therefore, during the nebulization, should be operated in a standardized manner, especially their own home nebulization, to carefully study the instructions of the nebulizer, actively observe the child’s reaction state, after the nebulization, to use a towel to wipe the face, at the same time, with saline or plain water gargle, so that you can minimize the side effects of nebulization.
