Root Cause

Ice water immersion can cause peripheral vasoconstriction and shivering, potentially triggering cardiac arrhythmias in patients with heatstroke-related myocardial injury; aspirin does not lower core temperature and can worsen bleeding risk. Proper treatment involves cold water (not ice) immersion with skin massage, or evaporative cooling, and immediate EMS.

冰水浸泡可导致外周血管收缩和寒战，可能触发中暑相关心肌损伤患者的心律失常；阿司匹林不能降低核心体温，并会增加出血风险。正确治疗方法包括冷水（非冰水）浸泡并按摩皮肤，或蒸发冷却，并立即呼叫急救。

Workarounds

  1. 85% success Use cold water immersion (10-15°C, not ice water) with vigorous skin massage to maintain peripheral circulation. Monitor core temperature continuously; stop when temperature reaches 39°C.

Dead Ends

Common approaches that don't work:

  1. Give aspirin or ibuprofen for fever 90% fail

    These drugs do not lower core temperature and may cause coagulopathy or kidney injury; heatstroke is not a fever and requires physical cooling.

  2. Immerse in ice water for 10 minutes 70% fail

    Prolonged ice immersion can cause overcooling, shivering, and cardiac arrhythmias; target cooling rate is 0.2°C/min, stop at 39°C.

  3. Give oral fluids if patient is conscious 60% fail

    Heatstroke patients often have altered mental status and cannot safely swallow; aspiration risk is high. IV fluids are preferred.
