Which cephalosporin is used for inflammation of the lung? Cephalosporin is divided into 1-4 generations, the effect on Gram-positive cocci gradually decreases and the effect on Gram-negative bacilli gradually increases, so when the patient has lung inflammation, the common causative agent is Streptococcus pneumoniae, and 1-2 generations of cephalosporin should be used for treatment, such as cefazolin sodium pentahydrate, cefuroxime, etc. If the patient is considered to be gram-negative bacillus infection, 3-4 generations of cephalosporins can be used. When the patient is a patient with chronic obstructive pulmonary disease and bronchial dilatation, there is a possibility of drug-resistant bacteria, and enzyme inhibitors, such as cefoperazone sodium sulbactam sodium and cefoperazone sodium tazobactam sodium, are needed. At the same time, sputum culture examination can be perfected, and antibiotics can be changed according to the results of sputum culture. If the patient’s condition is serious, levofloxacin plus azithromycin can be applied in combination.
