RESUMO
Major 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.
