Heat Stroke Management

Initial Assessment and Interventions

The American Heart Association recommends immediately activating emergency services upon recognition of heat stroke symptoms, such as altered mental status with hyperthermia, and removing the patient from the hot environment to a cool area, removing excess clothing to facilitate cooling 1
The American College of Critical Care Medicine suggests assessing vital signs, including core temperature, with a target of below 39°C/102.2°F, and evaluating mental status and neurological function as indicators of severity 1, 2, 4
Monitoring for signs of organ dysfunction, which may include coagulopathy, muscle injury, and cardiovascular collapse, is crucial in heat stroke patients 1, 2

The American Heart Association recommends implementing whole-body (neck-down) cold water immersion (14-15°C/57.2-59°F) as the first-line cooling method, and continuing it for 15 minutes or until neurological symptoms resolve, whichever occurs first 1, 5
A cooling rate of ≥0.155°C/min is targeted for optimal outcomes, according to the Society of Critical Care Medicine 7

The American Heart Association suggests applying commercial ice packs to the neck, axilla, and groin areas, and using cold showers, ice sheets, and towels as alternative cooling methods when whole-body cold water immersion is unavailable 1, 5, 6

The Society of Critical Care Medicine recommends establishing intravenous access for fluid resuscitation, and providing cool liquids orally if the patient is conscious and able to swallow 1, 2, 8
Positioning the patient appropriately to maintain airway patency, and monitoring for and managing complications such as seizures, hypotension, or respiratory distress, are essential supportive care measures 2

The American Heart Association and the Society of Critical Care Medicine recommend continuously monitoring vital signs, especially core temperature, and assessing neurological status frequently to detect improvement or deterioration 1, 2, 4
Documenting cooling methods used, duration, and patient response, as well as recording fluid intake and output to assess hydration status, are crucial for ongoing monitoring and documentation 2, 4
