There can be longterm ulceration and damage to growth plates.In the weeks after injury, pain persists and a blackened crust ( eschar) develops.Symptoms include blood blisters and "blue-grey discoloration of the skin".
DOES WAYANG SPELLHUNTER WORK WITH FROSTBITE SKIN
In third degree frostbite, the layers of tissue below the skin freeze.At this stage, lasting cold sensitivity and numbness can develop.In the weeks after injury, this hardened, blistered skin dries, blackens, and peels.In second degree frostbite, the skin develops clear blisters early on, and the skin's surface hardens.In the weeks after injury, the skin's surface may slough off.In the affected areas, the skin is numb, and possibly swollen, with a reddened border. Early on, the primary symptom is loss of feeling in the skin.First degree frostbite is superficial, surface skin damage that is usually not permanent.A simplification of this system of classification is superficial (first or second degree) or deep injury (third or fourth degree). However, the degrees do not correspond to the amount of long term damage. Historically, frostbite has been classified by degrees according to skin and sensation changes, similar to burn classifications.
The symptoms of frostbite progress with prolonged exposure to cold. Īreas that are usually affected include cheeks, ears, nose and fingers and toes. The first formal description of the condition was in 1813 by Dominique Jean Larrey, a physician in Napoleon's army, during its invasion of Russia. Frostbite has also played an important role in a number of military conflicts. The most common age group affected is those 30 to 50 years old. Rates may be as high as 40% a year among those who mountaineer. The number of cases of frostbite is unknown. Evidence was documented in a pre-Columbian mummy discovered in the Andes. Įvidence of frostbite occurring in people dates back 5,000 years. Amputation should be considered a few months after exposure in order to consider whether the extent of injury is permanent damage and thus necessitates drastic treatment. For severe injuries, iloprost or thrombolytics may be used. The use of ibuprofen and tetanus toxoid is recommended for pain relief or to reduce swelling or inflammation. Rubbing or applying force to the affected areas should be avoided as it may cause further damage such as abrasions.
Rapid heating or cooling should be avoided since it could potentially cause heart stress or cause burning. Treatment is by gradual rewarming, generally from cold to warm water, and should only be done when consistent temperature can be maintained and refreezing is not a concern. Prevention is by wearing proper, fully-covering clothing, maintaining hydration and nutrition, avoiding low temperatures, and minimizing strenuous physical activity while maintaining a sufficient core temperature. A bone scan or MRI may help in determining the extent of injury. Severity may be divided into superficial (1st and 2nd degree) or deep (3rd and 4th degree). The underlying mechanism involves injury from ice crystals and blood clots in small blood vessels following thawing. Other risk factors include drinking alcohol, smoking, mental health problems, certain medications, and prior injuries due to cold. People who are exposed to low temperatures for prolonged periods, such as winter sports enthusiasts, military personnel, and homeless individuals, are at greatest risk. Complications may include hypothermia or compartment syndrome. Swelling or blistering may occur following treatment. This may be followed by clumsiness with a white or bluish color to the skin. The initial symptom is typically numbness. Most often, frostbite occurs in the hands and feet.
