摘要多发伤是一种涉及机体多部位的严重创伤，危害大，病死率高。目前其诊断主要由各不同解剖部位创伤性疾病组合的“疾病集”构成。多发伤具有明确的病因、特征性病理生理改变，救治措施不同于单发创伤。笔者呼吁将其视为一种独立的“疾病”类型，而非“疾病集”。依照“柏林定义”的多发伤是完全符合现阶段关于独立“疾病”的分类标准，笔者探讨将多发伤确认为一种独立“疾病”类型对其预防、救治及创伤外科学科发展的重要意义。

abstractsPolytrauma represents severe injuries to multiple body regions, which is associated with high risk of complications and mortality. The definition of polytrauma relies on the basic concept of a combination of injuries that cause a life-threatening condition. The authors strongly call on the healthcare community to list polytrauma as a single disease in the international classification of diseases, rather than "disease combination". Because polytrauma has definite etiology and unique pathophysiological changes after polytrauma, treatment models are different from single trauma. Polytrauma can certainly fulfil any practical and nosological criteria of a single disease according to Berlin definition. The authors explore the importance of polytrauma as a single disease in preventive intervention strategies, therapeutic measures and traumatology development in the future.
