Acute pneumonia requires hospitalization and absolute bed rest, otherwise it is very detrimental to the recovery from pneumonia. First of all, routine blood tests and chest radiographs should be performed to see if there is any pleurisy caused by extended pneumonia or elevated white blood cells in the routine blood. If there is an elevated white blood cell count, the pneumonia may be caused by a bacterial infection and will require intravenous antibiotic treatment. Penicillin or cephalosporin antibiotics are more commonly used clinically, and erythromycin can be used for treatment if there is an allergy to these two drugs. In addition, it is also necessary to check whether there is a positive mycoplasma antibody, if it is mycoplasma infection, it is necessary to use macrolide antibiotics intravenous drip treatment, such as azithromycin or erythromycin, the effect is good, but these two drugs have a certain stimulating effect on the gastric mucosa, it is best not to inject drugs when fasting, otherwise there will be damage to the stomach mucosa. At the same time, it is also necessary to take cough and phlegm medicines for treatment, such as Ambroxol Hydrochloride or Pulmonary Cough Compound.
