Hypothermia and Cold Weather Injuries.

Area of Science:

• Emergency Medicine
• Environmental Health

Background:

• Cold-related injuries such as hypothermia, frostbite, and immersion foot disproportionately impact vulnerable populations.
• Effective prevention and treatment strategies are crucial for managing these conditions.

Purpose of the Study:

• To outline current best practices for preventing and managing cold-related injuries.
• To detail diagnostic and therapeutic interventions for hypothermia and frostbite.

Main Methods:

• Review of established guidelines and clinical evidence for cold injury management.
• Description of preventative measures, including appropriate clothing.
• Explanation of diagnostic criteria and treatment protocols for hypothermia and frostbite.

Main Results:

• Hypothermia management involves external/internal rewarming and warmed saline. Frostbite requires protection, prevention of refreezing, and potentially rapid rewarming with thrombolytics.
• Technetium 99mTc pyrophosphate scintigraphy or MRI aids frostbite prognosis.
• Tissue plasminogen activator within 24 hours of rewarming significantly reduces amputation rates.

Conclusions:

• Proper clothing and layering are essential for preventing cold injuries.
• Prompt and appropriate rewarming, alongside advanced treatments like tissue plasminogen activator for severe frostbite, improves patient outcomes.
• Immersion foot requires specific management, avoiding rapid rewarming and considering amitriptyline for pain.
