Episode notes
How Frostbite Damages Tissue
- Frostbite begins with vasoconstriction that prioritizes core blood flow and causes ischemia in extremities.
- Ice crystals form outside and then inside cells, dehydrating and rupturing them, which leads to cell death.
Rewarming Can Harm Tissue
- Rewarming triggers reperfusion injury that causes inflammation and severe pain.
- Delays in restoring healthy blood flow increase necrosis risk and worsen outcomes.
Use Controlled Rapid Rewarming
- Rapid rewarming in a circulating water bath at 40–42°C is the modern standard for frostbitten extremities.
- Maintain water circulation and temperature to ensure effective and tolerable rewarming.
