Pediatric nebulizer inhalation therapy is an important tool in today’s outpatient or home treatment of respiratory diseases such as asthma, including some wheezing diseases, allergic cough, pneumonia, and other diseases. Nebulization is a form of drug delivery just like oral medication, intravenous fluid administration, and intramuscular drug administration. Nebulized inhalation therapy uses a nebulizing device to deliver 1-5 micron particles of medication directly into the respiratory tract and lungs, which is fast and effective because it works precisely on the diseased lungs. This is a fast and effective method because it can be applied precisely to the diseased lungs. It is also a popular treatment for many pediatricians because the dose is small due to the local application of the drug. Nebulization is more effective, with less medication and fewer side effects, and is safer than oral medication and infusions. Nebulized inhalation can treat the following diseases: acute attacks of bronchial asthma, preventive treatment of bronchial asthma; wheezing diseases such as capillary bronchitis, asthmatic pneumonia, asthmatic bronchitis, occlusive bronchitis; cough-related diseases such as cough variant asthma, cough after respiratory infection, eosinophilic bronchitis, allergic cough, pertussis; mycoplasma pneumonia; acute laryngitis; bronchopulmonary dysplasia; tracheal intubation and pre- and post-operative bronchoscopy applications.
