Episode notes
Historical Examples Of Catastrophic Cold Injury
- Ian recounts historical examples: Napoleon's 1812 retreat and WWII amputations for frostbite.
- These stories illustrate how catastrophic cold injuries were in past wars.
Use A Two‑Hour Evacuation Decision Window
- If you can reach a facility for proper rewarming within ~2 hours, defer field rewarming and evacuate.
- If evacuation will exceed that, rewarm in place but ensure the limb will not refreeze and will be protected during transport.
Rewarm Until Perfusion Returns
- Rewarm until full erythema and perfusion return, typically 20–30 minutes, sometimes up to 45 minutes.
- Expect vesicles to form over 6–12 hours; hemorrhagic blisters indicate deep injury and high risk of tissue loss.
