If the cough is caused by upper respiratory tract infection or allergy, including allergic rhinitis, allergic pharyngitis and enlarged tonsils, the decision to add antibiotics needs to be based on whether the blood test indicates infection. If the baby has a rash or allergic rhinitis, anti-inflammatory and anti-allergic medications can be added, including inhaled glucocorticoid budesonide suspension, oral montelukast sodium chewable tablets, procaterol hydrochloride oral solution, and desloratadine dry suspension. If it is caused by lower respiratory tract infection, including fine bronchitis, bronchopneumonia, etc., it is necessary to consider whether to hospitalize antibiotic infusion treatment according to the severity of blood routine and chest X-ray. At the same time, oral anti-inflammatory and anti-allergic drugs can be used to shorten the course of the disease and relieve the baby’s pain, and traditional Chinese medicine and pediatric massage can be used to shorten the course of the disease.
