Abstract: Long-term intrapulmonary complications of severe pneumonia primarily include chronic conditions that currently have no specific treatment，persist over time，and exert varying degrees of long-time or even life-long impact on patients. These complications occur following severe pneumonia，and mostly present as a continuous process of pneumonia，with no clear onset time. Common complications include organizing pneumonia，bronchiolitis obliterans/obliterative bronchitis，and bronchiectasis. Severe long-term complications can lead to symptoms such as shortness of breath，wheezing，dyspnea，and persistent moist rales in the lungs. They may also result in recurrent hospitalizations due to repeated respiratory infections，impairing both pulmonary and physical growth and development in patients，while milder cases may present no clinical symptoms. Once long-term complications occur，treatment outcomes are generally poor. Thus，the keys in diagnosis and treatment lie in early screening，prevention，diagnosis， and intervention.
