Heat-Related Illnesses
Abstract
This chapter in the 2nd edition of the Management of Wilderness and Environmental Emergencies provides background material in the following areas: Physics of heat transfer, physiology of human body temperature regulation, the CNS interface between thermosensors and thermoregulatory effectors, skin blood flow and vasodilation, and acclimatization. The heat illnesses coverage includes information on predisposing factors, thermometry, and fever versus hyperthermia. The review of heat illnesses includes heat cramps, heat edema, heat syncope, heat exhaustion and heat stroke. Treatment coverage includes the differential diagnosis, classical versus exertional forms of heatstroke, the systematic and cellular approach to pathophysiology which includes an organ by organ analysis. The specifies of treatment provides insight to electrolyte abnormalities, acid- base abnormalities and the ABC's of therapy including cooling, modalities, adjunctive measures and prevention. Keywords: Heat stress physiology.
