Furthermore, the course will teach you the rescue protocol and the first treatment of injured people who have suffered a trauma, that is, an event caused by a considerable amount of energy acting on the body causing damage. This type of aid is therefore aimed not only at injured people who have suffered road accidents, for example, but also at people who have drowned, been electrocuted, burned, or who have suffered gunshot wounds, since in all these cases the injuries are caused by the dissipation of energy on the body. We speak of polytrauma when a person has suffered trauma to more than one system. Even if a person has all four limbs broken, but the skin is not damaged and there are no injuries to vessels or nerves, it is therefore not polytrauma.
The time between the trauma event and the rescue is of great importance, since the shorter the time interval, the greater the possibility that the traumatized person will survive or in any case suffer the least possible amount of damage. The SVT indicates the concept of the golden hour, underlining how the time between the event and the centralization at a "trauma center" (centers equipped 24 hours a day to immediately carry out the necessary tests) must not be longer than 60 minutes, a limit beyond which there is a clear drop in the chances of a positive outcome.
