根因分析

直接敷冰会导致血管收缩，减少散热，并引发寒战产生更多热量；还可能导致皮肤损伤。

English

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

解决方案

  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。
