First of all, we need to understand which kind of bronchitis the patient has. Bronchitis is divided into acute bronchitis and chronic bronchitis, most patients with acute bronchitis have symptoms of acute upper respiratory tract infection, including fever, sore throat, cough, and some patients may have wheezing; such patients will first symptomatically reduce fever, symptomatically stop cough, and symptomatically calm wheezing; if the patient is clearly combined with bacterial infection, reasonable antibacterial drugs will be selected. In chronic bronchitis, the main principles of treatment are to control infection, relieve spasm and asthma, and stop coughing and phlegm; acute attacks of chronic bronchitis are often caused by airway infections, because they are chronic diseases, especially in elderly patients, with common pathogenic bacteria, and appropriate antibacterial drugs will be given according to the relevant situation, and sputum bacteriological examination will be given to clarify the pathogenic bacteria. Then, precise antimicrobial drugs will be given. In addition, to relieve spasm and asthma, most patients will be combined with wheezing, the patient will have obvious dyspnea, then will choose nebulization therapy drugs, intravenous drugs, oral asthma drugs to relieve airway spasm, the patient will also be more obvious cough, sputum is also not easy to drain, will give their cough and sputum drugs.
