Metabolic and electrolyte abnormalities during heat exhaustion.

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 ...

Electrocardiographic manifestations: electrolyte abnormalities.

Because myocyte depolarization and repolarization depend on intra- and extracellular shifts in ion gradients, abnormal serum electrolyte levels can have profound effects on cardiac conduction and the electrocardiogram (EKG). Changes in extracellular potassium, calcium, and magnesium levels can change myocyte membrane potential gradients and alter the cardiac action potential. These changes can ...

Metabolic Abnormalities in Alcoholic Patients: Focus on Acid Base and Electrolyte Disorders

Alcoholic patients commonly develop a variety of acid-base and electrolyte disturbances. The aim of this review is to describe the most commonly encountered abnormalities and their significant role in the patients’ morbidity and mortality. Physicians should be aware of these clinically important disturbances caused by alcohol abuse and their underlying pathophysiological mechanisms involved for...

Distinguishing metabolic heat from condensation heat during muscle recovery.

When a thermopile is used to measure the heat production of isolated muscle, the muscle is surrounded by gas saturated with water vapour, initially in equilibrium with the muscle. After contraction, the osmolarity of the muscle is raised so that it is no longer in equilibrium with the gas around it, and condensation will occur. When artificial muscles of known osmolarity were placed on a thermo...
