The treatment of rhinitis in young children should be based on the etiology of the disease, including surgical treatment, antibiotics, glucocorticoids, nasal rinsing, mucolytic pro-discharge agents, decongestants, and the treatment of allergic rhinitis. 1. Define the etiology: if accompanied by adenoid hypertrophy, adenoidectomy can be considered; if accompanied by nasal polyps, polypectomy can be performed, etc. 2. Antibiotics: (1) Acute rhinitis: if combined with bacterial infection, antibiotics can be applied systemically. Penicillin antibiotics are preferred, followed by macrolide antibiotics, such as azithromycin. (2) Chronic rhinitis: antibiotics are not recommended unless there is purulent nasal discharge or laboratory evidence suggesting infection. (3) Glucocorticosteroids: Nasal glucocorticosteroids are now used as the first-line drugs in the treatment of acute and chronic rhinitis due to their significant anti-inflammatory and anti-edema effects. 4. Nasal rinsing: Nasal rinsing with saline or 2.2%~2.3% hypertonic saline can improve the symptoms and the local microenvironment of the nasal cavity. 5. Mucus dissolving and promoting the discharge of agents: such as Xanadu Bei drops, with the function of diluting mucus and improving the activity of cilia. 6. Decongestants: e.g. Seroquel, can be considered for children with persistent and severe nasal congestion. 7. Allergic rhinitis: its treatment should include environmental control, medication, immunotherapy and so on. Environmental control is to reduce allergen inhalation. Drug therapy includes nasal glucocorticoids, nasal or systemic antihistamines such as loratadine. Immunotherapy is desensitization or desensitization. When rhinitis occurs in young children, parents should take them to the hospital in time, and should not use medication by themselves, but should standardize the treatment under the guidance of the doctor.
