Abstract: Recent pulmonary complications of severe pneumonia in children are an important reason for the aggravation of their lung conditions and the prolongation of hospital stay. They can also cause long-term complications such as oblusive bronchiolitis，bronchiectasis，and lung damage. In severe cases，they can even lead to death. In recent years，with the change of the pathogen spectrum of pneumonia infection in children and the increase in pathogen drug resistance，in addition to the common pulmonary complications such as atelectasis，empyema，pyopneumothorax，lung abscess and necrotizing pneumonia，previously rare complications such as pulmonary embolism and plastic bronchitis have emerged in the recent pulmonary complications. This article will elaborate on the clinical characteristics，diagnostic methods and management principles of short-term pulmonary complications of severe pneumonia，with the aim of being helpful for the early detection and timely management of short-term pulmonary complications of severe pneumonia，reducing long-term complications and lowering the mortality rate of pneumonia in children.
