Root Cause

Ice water immersion can cause peripheral vasoconstriction and shivering, increasing cardiac workload and triggering arrhythmias in patients with underlying heart conditions; aspirin has no effect on core temperature and may cause bleeding if the patient is taking anticoagulants.

冰水浸泡可能导致外周血管收缩和寒战，增加心脏负荷，在患有潜在心脏病的患者中引发心律失常；阿司匹林对核心体温没有影响，如果患者正在服用抗凝剂，可能导致出血。

Workarounds

  1. 90% success Use cold water immersion (15-20°C, not ice water) with continuous monitoring of vital signs. If shivering occurs, stop immersion and use evaporative cooling (mist and fan). Example: `Fill a tub with cool tap water (15-20°C), immerse the patient up to the neck, and monitor heart rate and consciousness every 2 minutes. If shivering starts, remove patient and use a spray bottle with fan.`

  2. 85% success For patients with cardiac history, use evaporative cooling: spray tepid water (30°C) on the skin and direct a fan at the patient. Example: `Set up a fan, spray the patient's skin with water at 30°C, and monitor core temperature every 5 minutes until it drops below 39°C.`

Dead Ends

Common approaches that don't work:

  1. 95% fail

    Giving aspirin or ibuprofen for heatstroke can mask symptoms and does not reduce core temperature; it may cause gastrointestinal bleeding or kidney damage.

  2. 80% fail

    Using ice water immersion without monitoring for shivering can increase metabolic heat production and worsen the condition, especially in elderly patients.

  3. 90% fail

    Applying rubbing alcohol to the skin for cooling is dangerous as it can be absorbed and cause toxicity, and it does not effectively lower core temperature.
