Treatment


Exercise-Associated Muscle Cramps

  • Stop activity
  • Hydrate with sodium-containing fluids
  • Mild stretching
  • Massage muscle spasm
  • Lay flat to assist  with redistribution of blood flow to cramping muscles

Heat Syncope

  • Move to shade
  • Monitor vital signs
  • Elevate legs above level of head
  • Rehydrate

Exercise (Heat) Exhaustion

  • Measure body-core temperature (rectal)
  • Remove excess clothing
  • Cool the athlete with fans, ice towels, or ice bags if temperature is in excess of 102°F
  • Place the athlete in a cool and/or shaded environment
  • Start fluid replacement
  • Transfer care to a physician if IV fluids are needed or if recovery is not rapid

Exertional Heatstroke

  • Measure body-core temperature (rectal) to differentiate between heat exhaustion and heatstroke (≥104°F = likely heatstroke)
  • Assess cognitive function
  • Lower body-core temperature as quickly as possible
  • Monitor temperature every 5-10 minutes during cooling. Stop cooling when temperature is 100°F-101°F to prevent overcooling
  • If a physician is available on-site, transport to a medical facility may not be necessary so immersion can continue
  • If a physician is not available on-site, aggressive first-aid cooling should be initiated on-site and continued during transport to a medical facility (Portable cooling)
  • Activate emergency medical system
  • Monitor vital signs and other signs and symptoms of heat stroke
  • During transport and when immersion is not feasible, other methods can be used to reduce body temperature: remove clothing; sponge down with cool water and apply cold towels; apply ice bags to as much of the body as possible (especially the major vessels in the armpit, goin, and neck); provide shade; fan the body
  • Manage airway (if needed)
  • Monitor for organ-system complications

Exertional Hyponatremia

  • Attempt to differentiate between exertional heat exhaustion and hyponatremia
  • Attempt to differentiate between heatstroke and hyponatremia
  • If hyponatremia is suspected, immediately transfer to an emergency medical center via emergency medical services
  • Do not administer fluids until a physician is consulted
