If the symptoms are mild, oral medication can be given. If oral medication is ineffective or the symptoms are severe, then appropriate injections should be given. 1. Acute trachea-bronchitis: acute inflammation of the mucous membrane of the trachea-bronchial tubes, with cough and sputum as the main symptoms. If the symptoms are mild, Ambroxol tablets can be given orally. If the symptoms of coughing are severe, aminoglutethimide hydrochloride injection can be given to relieve cough and resolve sputum. If there is evidence of bacterial infection, cephalosporins such as cefmetazole sodium for injection can be given as intravenous drip. 2. Mycoplasma pneumonia: acute lung inflammation caused by Mycoplasma pneumoniae infection, persistent paroxysmal cough is a more typical manifestation of Mycoplasma pneumonia. If the scope of pneumonia lesions is wide, macrolide antibiotics are preferred, such as azithromycin for injection, and those who are not sensitive to macrolides can choose to breathe fluoroquinolones, such as moxifloxacin hydrochloride sodium chloride injection. 3. Asthma: mainly manifested as paroxysmal wheezing, cough or chest tightness and other symptoms. If the symptoms are mild, budesonide formoterol powder inhaler can be given. If the symptoms are severe, such as cough, wheezing caused by dyspnea, can be given theophylline such as aminophylline injection IV, can also be given glucocorticosteroids such as injection of methylprednisolone sodium succinate IV drip, to relieve the symptoms. Cough can also be caused by other diseases, such as digestive system diseases, cardiovascular system diseases, etc., because the causes of cough are different, the choice of drugs is different. If the symptoms of repeated coughing are not relieved or aggravated, it is recommended to consult a doctor in time to clarify the cause of the disease, and choose the appropriate medication under the guidance of the doctor for treatment.
