摘要重大自然灾害严重威胁人类生命健康。地震等自然灾害发生后，幸存者往往被困于地面、建筑物等坍塌形成的与外界相对隔离、进出受限、环境复杂且存在潜在或明确危害的狭小空间内，大大增加了救援难度。规范合理、适用于重大自然灾害狭小空间现场的创伤评估与急救工作流程对于挽救创伤患者生命、改善结局至关重要。本文围绕重大自然灾害狭小空间现场的创伤评估与急救，从现场伤情评估、稳定生命体征、止血和包扎、创伤后抗感染以及救出和转运等方面出发，形成适用于重大自然灾害狭小空间的创伤急救工作流程，有助于实现灾害现场第一时间高效救治，提高伤员抢救成功率、降低致死致残率、改善预后。

abstractsMajor natural disasters seriously threaten human life and health. After earthquakes and other catastrophes, survivors are often trapped in the confined spaces caused by the collapse of ground and buildings, with relative separation from the outside world, restricted access, complex environment, and oncoming or ongoing unsafety, leading to the rescue extremely difficult. In order to save lives and improve the outcome more efficiently in the confined spaces after natural disasters, it is very important to standardize and reasonably apply the trauma assessment and first aid workflow. This study focuses on trauma assessment and first aid. From the aspects of trauma assessment, vital signs stabilization, hemostasis and bandaging, post-trauma anti-infection, and the transportation of patients, a trauma first aid work process suitable for a small space of a major natural disaster is formed, It is helpful to realize the immediate and efficient treatment of trauma in the confined spaces after natural catastrophes, to reduce the rate of death and disability and improve the outcome of patients.
