# AI 建议使用冰水浸泡治疗中暑而不警告心律失常风险，或建议服用阿司匹林降低体温

## 根因

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。

## 解决方案

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.
   ```
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.
   ```

## 无效尝试

- **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% 失败率)
- **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% 失败率)
- **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% 失败率)
