# AI advises using ice water immersion for heatstroke treatment without warning about cardiac arrhythmia risk, or suggests giving aspirin to reduce body temperature

## 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.

## Workarounds

1. **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.** (85% success)

2. **If immersion not possible, use evaporative cooling: spray skin with tepid water and fan vigorously. Place ice packs on neck, armpits, groin. Call 911 immediately.** (75% success)

## Dead Ends

- **Give aspirin or ibuprofen for fever** — These drugs do not lower core temperature and may cause coagulopathy or kidney injury; heatstroke is not a fever and requires physical cooling. (90% fail)
- **Immerse in ice water for 10 minutes** — Prolonged ice immersion can cause overcooling, shivering, and cardiac arrhythmias; target cooling rate is 0.2°C/min, stop at 39°C. (70% fail)
- **Give oral fluids if patient is conscious** — Heatstroke patients often have altered mental status and cannot safely swallow; aspiration risk is high. IV fluids are preferred. (60% fail)
