The length of time to heal from lobar pneumonia in children is related to the severity of the infection, the patient’s underlying status, and the presence or absence of complication formation, and cannot be generalized. Lobar pneumonia begins as a localized alveolar lesion and rapidly spreads to a segment of the lung or to the entire lobe. The disease is clinically acute, lasting approximately 1 week, and often begins with high fever and chills, followed by chest pain, cough, rust-colored sputum, dyspnea with signs of pulmonary solidity, and peripheral leukocytosis. The usual course of treatment for lobar pneumonia in children is 2-4 weeks, and the duration of treatment varies depending on the child’s physical condition or the infecting pathogen. In cases of refractory lobar pneumonia, such as those caused by mycoplasma, the course of treatment can be 1 month or longer; if the distal airway mucosa is necrotic and blocked on tracheoscopy, the course of treatment for such lobar pneumonia may be even longer. In addition, care should be taken to keep the air in the room clear and the temperature appropriate during the illness, and to improve the child’s own immunity with appropriate exercise.
