In the presence of pneumonia, the medications used for infusion often need to be determined by the type of pneumonia infection. The first step is to check the blood count, C-reactive protein, and antibodies to mycoplasma. If there is an elevation of white blood cells in the routine blood, it means that the pneumonia is caused by a bacterial infection, and the infusion can be done with penicillin or levofloxacin, cefradine, ceftriaxone, or cefoperazone, which are all effective. If there is simply an increase in C-reactive protein, it is likely to be a viral infection and can be treated routinely with ribavirin or Xiyampin for antiviral treatment. If there is a positive mycoplasma antibody, pneumonia caused by Mycoplasma pneumoniae infection can be treated with azithromycin, or erythromycin. In addition, the infusion can be routinely used some vitamins, which can enhance their resistance. If there is wheezing, aminophylline can also be used to relieve the symptoms of wheezing. At this time, if the cough is heavy, you can also use cough and phlegm medicines, such as lung power cough combination.
