The first step is to determine the severity of the pneumonia and the specific condition of the organism. In mild pneumonia, with no underlying disease, oral antibiotics are generally sufficient. In more severe pneumonia or patients with serious underlying diseases, the main infusion drug is antibiotics. Doctors will choose the appropriate antibiotic treatment according to the clinical characteristics of pneumonia, including the patient’s age, clinical symptoms, signs, lung CT and other examinations, as well as the pathogenic examination of sputum. Sodium azobactam for injection, etc. Cephalosporins include cefuroxime, ceftizoxime, cefoperazone sodium sulbactam sodium and other second or third generation cephalosporin antibiotics. Macrolides include azithromycin. Quinolones, such as levofloxacin injection and pazufloxacin mesylate injection. Aminoglycosides include etimesine sulfate injection or amikacin injection. If the patient has symptoms of high fever, saline or glucose may be administered for rehydration and fever reduction. For patients with severe pneumonia, the doctor may choose more advanced antibiotics for treatment, depending on the pathogenic examination of the sputum and the results of the drug sensitivity test to select a sensitive antibiotic.
