heat cramp

Etymology: AS, haetu + crammian, to fill
any cramp or painful spasm of the voluntary muscles in the arm, leg, or abdomen caused by depletion in the body of both water and salt. It usually occurs after vigorous physical exertion in an extremely hot environment or under other conditions that cause profuse sweating and depletion of body fluids and electrolytes. The victim should be moved to a cooler place and given salt-containing fluids. Also called cane-cutter's cramp, fireman's cramp, miner's cramp, stoker's cramp. See also heat exhaustion.

heat cramp

Skeletal muscle spasm caused by the excess fluid and/or electrolyte loss that occurs with profuse sweating. The usual muscles affected are those used during work, i.e., the hand, arm, or leg muscles. The cramps may come on during work or up to 18 hr after completing a work shift.

Treatment

The patient should be rehydrated by drinking cool water or an electrolyte-containing drink, such as diluted juice or a commercially marketed sports drink. The severity of the cramp can be decreased through passive stretching and/or massage of the muscle. Severe heat cramps may require the use of an intravenous electrolyte solution, such as normal saline or Ringer's solution.

Prevention

Heat cramps may be prevented by maintaining proper hydration by drinking water or commercial electrolyte drinks before and during exposure to hot, humid environments. Normal dietary amounts of electrolytes and salt should be encouraged during meals.
