AI advises using ice water immersion for heatstroke treatment without warning about cardiac arrhythmia risk, or suggests giving oral fluids to an unconscious heatstroke victim
ID: safety/heatstroke-ice-water-arrhythmia
Root Cause
Ice water immersion can cause shivering (which generates heat) and may trigger cardiac arrhythmias in heatstroke patients with compromised cardiovascular systems; oral fluids given to an unconscious patient risk aspiration and airway obstruction.

冰水浸泡可能引起寒战(产生热量),并可能在中暑患者心血管系统受损时诱发心律失常;给失去意识的患者口服液体有误吸和气道阻塞的风险。

90% success For heatstroke (core temp >40°C with altered consciousness): 'Call 911 immediately. Move patient to shade. Cool by immersing in cold water (10-15°C, not ice water) if possible, or apply cold packs to neck, armpits, and groin. Fan aggressively. Do NOT give oral fluids if unconscious. Monitor for shivering and cardiac changes.'

95% success For heat exhaustion (core temp <40°C, conscious): 'Move to cool area, loosen clothing, give cool water or sports drink slowly. Apply cold compresses. If symptoms worsen or last >1 hour, seek medical help.'

Dead Ends
Common approaches that don't work:
-
85% fail
Ice water can cause peripheral vasoconstriction (reducing heat loss), shivering (increasing heat production), and cardiac arrhythmias. Cold water (10-15°C) is preferred over ice water, and cooling should be monitored.
-
95% fail
Unconscious patients cannot swallow safely; fluids can enter the airway, causing aspiration pneumonia or choking. IV fluids are required for severe cases.
-
75% fail
Alcohol can be absorbed through skin and cause toxicity; cold packs on extremities cause vasoconstriction, reducing heat dissipation. Apply cold packs to neck, armpits, and groin instead.
