Severe burn is a circumstantial pathology, most often accidental but more and more caused by voluntary acts. In the initial phase, the failures encountered are essentially hemodynamic, respiratory and metabolic, placing the emergency physician and the intensivist at the centre of medical care. The role of the pre-hospital physician is essential but often difficult due to the circumstances of intervention. First actions and treatments initiated as well as the evaluation of gravity can favorably modify the prognosis when they are well carried out. In view of this, we will unfold the different stages of pre-hospital care to implement in the event of severe burn.
