The course of treatment for patients with bronchitis hanging is usually 5-7 days, and the exact duration is mainly based on the patient’s symptoms. If the patient has a fever, the medication can be considered stopped 3 days after the fever symptoms disappear. Most patients with bronchitis do not require sedation, but only symptomatic application of oral medications and symptomatic eating of cough and phlegm medicines. Bronchitis is a self-limiting disease of the lower respiratory tract infection and does not require treatment, and some patients get better on their own. If the patient has a strong cough, take symptomatic cough medicines. If there is a lot of phlegm, take symptomatic phlegm-reducing drugs. Generally, only elderly people with combined underlying diseases, people with immunosuppression, or patients whose infections are not well controlled by oral medications may need to be sedated. For normal patients with bronchitis, only symptomatic oral medications are needed and no static dosing is required.
