Episode 21 - Frostbite & Peripheral Cold Injuries

Frostbite is a serious cold-induced injury caused by prolonged exposure to freezing temperatures, leading to ice crystal formation in tissues. We discuss the four degrees of frostbite severity, from mild frostnip to full-thickness necrosis requiring amputation. Additional peripheral cold injuries, such as chilblains, trench foot, and non-freezing cold injuries, are examined. Treatment focuses on controlled rewarming, pain management, and preventing further tissue damage, while prevention strategies emphasize proper clothing, hydration, and environmental awareness.
