根因分析
冰水浸泡（1-5°C）可能导致外周血管收缩和寒战，初期使核心温度升高，并可能在有电解质失衡的患者中引发心律失常；对失去意识的受害者进行口服补液有误吸性肺炎风险；正确治疗是用温水主动降温并立即送医。
English
Ice water immersion (1-5°C) can cause peripheral vasoconstriction and shivering, which increase core temperature initially and may trigger cardiac arrhythmias in patients with electrolyte imbalances; oral rehydration in unconscious victims risks aspiration pneumonia; proper treatment is active cooling with tepid water and immediate hospital transfer.

For heatstroke (core temp >40°C with altered consciousness): 1) Move victim to shade/cool area. 2) Remove clothing. 3) Apply cool water (20-25°C) to entire body using a spray bottle or wet cloths, then fan vigorously. 4) Place ice packs on neck, armpits, and groin (but not full ice bath). 5) If conscious and able to swallow, give small sips of cool water or sports drink. 6) Call emergency services immediately. Do not use ice water immersion unless you are under direct medical supervision.

If no water available, use evaporative cooling: cover victim with a wet sheet and fan continuously. Monitor core temperature (rectal if possible) and stop active cooling when temp reaches 39°C to avoid overshoot hypothermia. Follow WMS guidelines: https://www.wms.org/guidelines

Ice water immersion (1-5°C) is sometimes used in controlled hospital settings but is not recommended for field use; it can cause shivering which generates heat, and rapid vasoconstriction reduces heat dissipation; tepid water (20-25°C) is more effective and safer.

Trying to give oral fluids to an unconscious or confused heatstroke victim can lead to choking, aspiration pneumonia, or vomiting; IV fluids are needed but require medical training.

Relying on antipyretics (e.g., acetaminophen, ibuprofen) to lower core temperature is ineffective because heatstroke involves failure of thermoregulation, not a fever; these drugs can worsen liver or kidney damage.
