Root Cause

Direct ice application causes vasoconstriction, reducing heat dissipation, and triggers shivering which generates more heat; it can also cause skin damage.

中文步骤

  1. 将患者移至阴凉处，脱去多余衣物，用凉水（非冰水）湿润皮肤并扇风。可使用喷瓶或湿布。
  2. 如果清醒，少量多次饮用凉水或电解质饮料。不要给予含糖或酒精饮料。
  3. 立即呼叫急救服务；中暑是需要医院治疗的医疗急症。

Dead Ends

Common approaches that don't work:

  1. 70% fail

    Using ice-cold water immersion for conscious patients can cause shock and cardiac arrhythmias.

  2. 80% fail

    Applying alcohol rubs to the skin is dangerous and ineffective for cooling.

  3. 60% fail

    Giving the patient cold drinks rapidly can cause stomach cramps and aspiration.
