  Frostbite can be prevented. Here are tips to help you stay safe and warm. […] Limit time outdoors when it’s freezing cold and wet or windy. Pay attention to weather forecasts and wind chill readings. The risk of frostbite increases the longer you’re in freezing conditions. And frostbite can happen in an instant if bare skin touches something cold, such as freezing metal. […] Dress in loose layers. Air trapped between the layers helps insulate you from the cold. Choose undergarments that wick moisture away from the skin. Next put on something made of fleece or wool. For the outer layer, wear something windproof and waterproof. Change out of wet gloves, hats and socks as soon as possible. […] Wear a hat or headband made for cold weather. Make sure it covers your ears. […] Wear mittens. Mittens provide better protection than do gloves. Under a pair of heavy mittens, also wear glove liners, which wick moisture away from the skin.

  The Wilderness Medical Society (WMS) convened an expert panel to develop a set of evidence-based guidelines for prevention and treatment of frostbite to guide clinicians and first responders and disseminate knowledge about best practices in this area of clinical care. […] The adage that prevention is better than treatment is especially true for frostbite, which is typically preventable and often not significantly improved by treatment. Underlying medical problems (including peripheral vascular disease, diabetes, Raynauds disease) may increase risk of frostbite, so prevention must address both environmental and health-related aspects. Frostbite injury occurs when tissue heat loss exceeds the ability of local tissue perfusion to prevent freezing of soft tissues (blood flow delivers heat). One must both ensure adequate perfusion and minimize heat loss to prevent frostbite.

  If a body part is frozen in the field, the frozen tissue should be protected from further damage. Remove jewelry or other constrictive extraneous material from the body part. Do not rub or apply ice or snow to the affected area. […] Most frostbite thaws spontaneously and should be allowed to do so if rapid rewarming cannot be readily achieved. […] According to the foregoing guidelines, rapid rewarming is strongly recommended. If field rewarming is not possible, spontaneous or slow thawing should be allowed. […] Recovery of thawed tissue partly depends on the level of tissue oxygenation in the postfreezing period. Oxygen may be delivered by face mask or nasal cannula if the patient is hypoxic (oxygen saturation 88%) or the patient is at high altitude above 4000 meters/13000 feet).

• #20 WMS Prevention and Treatment of Frostbite Guideline Summary

  https://www.guidelinecentral.com/guideline/40547/

  Preventive measures to ensure local tissue perfusion include: 1) maintaining adequate core temperature and body hydration; 2) minimizing the effects of known diseases, medications, and substances (including awareness and symptoms of alcohol and drug use) that might decrease perfusion; 3) covering all skin and the scalp to insulate from the cold; 4) minimizing blood flow restriction, such as occurs with constrictive clothing, footwear, or immobility; 5) ensuring adequate nutrition; and 6) using supplemental oxygen in severely hypoxic conditions (eg, 7500 m). […] A decision must be made whether to thaw the tissue. If environmental conditions are such that thawed tissue could refreeze, it is safer to keep the affected part frozen until a thawed state can be maintained. Prostaglandin and thromboxane release associated with the freezethaw cycle causes vasoconstriction, platelet aggregation, thrombosis, and, ultimately, cellular injury. Refreezing thawed tissue further increases release of these mediators, and significant morbidity may result. One must absolutely avoid refreezing if field thawing occurs.
