Lobar pneumonia is usually hospitalized for 7 to 10 days, and some patients may need a longer course of treatment, mainly depending on the severity of the patient’s condition and drug sensitivity, and the medication can be discontinued after the body temperature is normalized for 48 to 72 hours in general. Lobar pneumonia is mainly caused by Streptococcus pneumoniae infection, lesions involving more than one lung segment of lung tissue, mostly in young adults, common triggers for cold, drunkenness, fatigue and so on. Lobar pneumonia is characterized by acute onset, high fever, strong cough, rust-colored sputum, chest tightness and shortness of breath. The main treatments are anti-infective treatment (such as penicillin G, ceftriaxone sodium, levofloxacin, etc.), symptomatic supportive treatment and complication management. Antimicrobials for lobar pneumonia should be used for at least 5 days, and most patients need 7 to 10 days, with more time needed for severe cases. The medication can be stopped only when the body temperature is normalized for more than 48～72 hours. It is recommended that patients with symptoms should go to the respiratory department of the hospital in time. All the above drugs should be used under the guidance of professional physicians and pharmacists.
