Heat Exhaustion and Heat Stroke

Metabolic and electrolyte abnormalities during heat exhaustion.

Accepted 27 September 1995 An 81-year-old man, resident of a poorly ventilated, ineffectively air-conditioned inner city apartment, presented during a heat wave (environmental temperature 80°-93°F and humidity 70%-80%) with hyperthermia, confusion and dehydration. The patient had mild hypertension, depression and urinary incontinence and was taking hydrochlorothiazide/methyldopa, nortriptyline ...

Return to exercise training after heat exhaustion.

CONTEXT Exertional heat exhaustion (HEX) is the most common form of heat illness experienced by athletes, laborers, and military personnel. Both dehydration stemming from a water and/or salt deficiency and a high ambient temperature must exist for HEX to occur. In the field, appropriate therapy can reduce recovery time. OBJECTIVE This manuscript provides clinical guidance regarding return to ...

Heat stroke.

Heatstroke is the most severe form of the heatrelated illnesses and is caused by an excessive rise in deep body temperature due to thermoregulatory failure. It is characterized primarily by hyperthermia usually with core temperature above 40.6o C (105o F), central nervous system dysfunction, metabolic derangement and coma. Heat stroke is the least common but most serious form of heat disorder. ...

Heat Stroke

When psychological and physiologic adaptation mechanisms become dysfunction to environment induced a period of elevated heat stress, heat-related emergencies occur. Heat-related illness may be trivial to life threatening. They represent a continuum of disorders such as heat edema, prickly heat, heat cramps, heat tetany, heat syncope, and heat exhaustion to critical disease well known as heat st...
