Abstract: Severe pneumonia in children remains a leading cause of mortality globally，and its prognostic evaluation is a critical and challenging aspect of clinical management. This review explores the pivotal factors influencing the prognosis of children with severe pneumonia， including pathogen characteristics，host immune response，the occurrence of complications，and the adequacy of initial therapeutic interventions. Prognostic assessment should extend beyond traditional survival rate metrics，and it is advocated to the establish a comprehensive evaluation framework encompassing acute disease management，organ function recovery，and prevention and management of complications，and an emphasis should be placed on long-term quality of life. This article explores the application value and limitations of clinical symptoms and signs，imaging modalities，serum biomarkers，and pulmonary function tests in predicting outcomes of severe pneumonia，in order to achieve. The transitioning of therapeutic goals from infection control to lung functional recovery.

摘要： 儿童重症肺炎是全球儿童死亡的主要原因之一，其预后评估是临床工作的核心与难点。文章讨论了影响重症肺炎患儿预后的关键因素，包括病原体特性、宿主免疫反应、并发症发生和初始治疗的恰当性。预后评估应超越传统的存活率指标，宜构建综合评估体系，涵盖急性期疾病管理控制、器官功能恢复、预防及控制并发症，并关注长期生活质量。文章旨在讨论基于临床症状与体征、影像学、血清生物标志物及肺功能检测等指标在重症肺炎预后判断中的应用价值与局限性，实现从抗感染到肺修复的综合目标转变。
