Heat Cramps
Treatment of Heat Cramps
Heat cramps may be relieved immediately by firm passive stretching of the involved muscle (eg, ankle dorsiflexion for a calf cramp). The patient should rest in a cool environment. Fluids and electrolytes should be replenished orally (1 to 2 L water containing 10 g [2 level teaspoons] salt or sufficient amounts of a commercial sports drink) or, for more rapid relief or when oral repletion is not possible, IV (1 to 2 L 0.9% saline solution). Adequate conditioning, acclimatization, and appropriate management of salt balance help prevent heat cramps.
