[Rescue workers: at the heart and head of the traumatic event].

With the traumatic event, the victim has suffered and fallen into a world of horror, violence and chaos. Emergency first aid is intended to give him a sign, to reach out to him so that the victim can return to the shore of the living world. The duality of technical and psychological first aid is necessary for the immediate and post-medical management of these highly traumatic interventions. These are important points of reference for the future of the subject as well as for the carer in the management of his individual or team stress.
