[Exertional heatstroke].
Exertional heatstroke is defined by an increase of core body temperature above 40 degrees C and neurological symptoms in association with exercise. It is related to excessive heat production, which overwhelms the endogenous mechanisms of thermoregulation. It is observed during intense physical activity in a hot and humid environment, most commonly in untrained subjects poorly adapted to such conditions. Clinical manifestations of exertional heatstroke are related to the induction of a systemic inflammatory response and a disseminated intravascular coagulation triggered by heat stress, which may lead to multiorgan dysfunction and death. Early management through rapid cooling is mandatory to prevent the devastating consequences of exertional heatstroke.
