Exertional Heat Stroke

Environmental emergency treatment template with rapid cooling priorities and critical interventions.

Query: What's the ED treatment for exertional heat stroke?

Summary

ED management of exertional heat stroke centers on rapid recognition and immediate initiation of aggressive cooling—ideally via cold water immersion—to lower the core temperature (with a target not below 39°C) while supporting airway, breathing, and circulation, along with IV fluid resuscitation and continuous core temperature monitoring.

StepIntervention DetailsCitation
RecognitionIdentify patients with core temperature ≥40°C and CNS dysfunction (altered mental status, seizures, or coma) in the context of strenuous activity.12
Rapid CoolingUse cold water immersion (gold standard for exertional heat stroke) to rapidly decrease core temperature, aiming never to cool below 39°C to prevent overshoot hypothermia.12
Adjunctive CoolingIf immersion is not feasible, employ conductive/convective cooling (cooling blankets) combined with evaporative techniques (mist with fans) for supplemental cooling.12
Temperature MonitoringInitiate continuous core temperature monitoring—preferably with a bladder or esophageal probe—to guide the cooling process accurately.12
Fluid ResuscitationBegin aggressive IV crystalloid rehydration to address the significant volume deficits common in exertional heat stroke and support hemodynamics.12
Supportive CareManage agitation/shivering with short-acting benzodiazepines as needed, avoid routine intubation (since delays in cooling can worsen the prognosis), and monitor for complications.12
