Heat Stroke

Heat stroke is characterized by hyperthermia with central nervous system dysfunction, including delirium, seizures, or coma, and may progress to multisystem injury. Traditional definitions use core temperature of at least 40°C, although measured temperature may be lower after spontaneous or prehospital cooling.

Classify the exposure phenotype because it directs prevention and prehospital operations. Classic heat stroke follows environmental heat exposure without exertion, whereas exertional heat stroke follows vigorous physical activity, usually but not invariably in hot or humid conditions.

For suspected exertional heat stroke, expert sports-medicine consensus recommends rapid on-site whole-body cooling and explicitly prioritizes cooling before transport. This approach is intended to minimize duration of severe hyperthermia; event guidance targets cooling within the first 30 minutes after collapse.

Rectal temperature assessment is specifically recommended for diagnostic assessment in athletic heat-stroke response systems. Continue core-temperature monitoring during treatment and confirm stable post-cooling core temperature for at least 15 minutes before initiating hospital referral in the athletic-event protocol.

Coordinate stabilization and cooling rather than sequencing routine emergency tasks ahead of cooling. In a patient with airway compromise, uncontrolled convulsions, shock, trauma, toxicologic concern, or another immediate threat, resuscitation proceeds concurrently with active cooling.

Following treatment of exertional heat stroke, hospital evaluation should include a general physical examination, cognitive testing for anterograde and retrograde amnesia, laboratory testing for renal, hepatic, and musculoskeletal injury, and continued core-temperature monitoring.

The available sources support assessment for coagulopathy as a clinically important heat-stroke complication, but they do not provide a source-supported laboratory panel, repeat-testing interval, fluid regimen, pharmacologic regimen, or disposition threshold. Individualize testing and monitoring to the exposure history, neurologic course, hemodynamics, urine output, renal function, hepatic injury, muscle injury, and bleeding risk.

Medication history should also identify agents that can worsen volume depletion or renal vulnerability. Dapagliflozin causes intravascular volume contraction and can produce symptomatic hypotension; its labeling highlights increased vulnerability in older adults and patients with renal impairment. accessdata fdaaccessdata fdaThis label may not be the latest approved by FDA. For current ... This does not establish causality for heat stroke, but it is clinically relevant during assessment of a heat-exposed patient with hypotension or acute kidney injury.

Athletes treated for exertional heat stroke should undergo hospital follow-up evaluation after cooling. In the cited event-management guidance, the hospital physician determines discharge, whereas the athlete's team physician determines return to competition.

Return-to-activity planning should account for neurologic recovery, cognitive findings, and evidence of renal, hepatic, musculoskeletal, or coagulation injury. The supplied sources do not provide validated U.S. laboratory targets, a fixed observation interval, or a universal graded return-to-play schedule; avoid presenting one as evidence-based from this search set.

International sports consensus recommends environmental heat policies with clear communication of heat risk and associated countermeasures, and it emphasizes clinician training in early recognition, rectal-temperature assessment, and rapid on-site whole-body cooling.

Exertional heat-stroke risk is thought to be increased by dehydration, age, body composition, prior illness, and other factors, although the review literature emphasizes that the evidence base for risk factors remains limited.
