Frostbite occurs when skin tissue and blood vessels are damaged from exposure to temperatures below 32 degrees fahrenheit. It mostly affects the toes, fingers, earlobes, chin, cheeks and nose, body parts which are often left uncovered in cold temperatures. Frostbite can occur rapidly or gradually, depending on the temperature conditions and how long it is exposed. Frostbite has three stages.
They are frost nip, superficial frostbite, and deep frostbite. Frost nip occurs when you have this pins and needles sensation and the skin turning very white and soft. This stage has no permanent damage and may be reversed by soaking in warm water or breathing warm breath on the affected area. Superficial frostbite is the stage of frostbite when blistering occurs. the skin feels numb, waxy, and frozen.
There are ice crystals that form in the skin cells and the rest of the skin remains flexible. Deep frostbite is the most serious stage of frostbite. The blood vessels, muscles, tendons, nerves, and bone all may be frozen. This stage leads to permanent damage, blood clots and gangrene, in severe cases. You have no feeling in the affected area and there usually isn't any blistering. Serious infections and loss of lips ac cur frequently when frostbite reaches this stage of its development.
However, even in deep frostbite, frozen lips may be saved if medical attention is obtained as soon as possible. If you are in a situation where a patient can't be transported to a hospital immediately, the following rewarming techniques may help until reaching an emergency facility. - Bring them indoors as soon as possible. - Apply warm towels or immerse the area in circulating warm water for twenty minutes.
However DO NOT rub or use hot water. - Do not hold the area near fire since the area may be burned due to the reduced feeling in the area. - Offer the patient warm coffee or tea, but never alcohol. - Keep the affected area raised. After re-warming, a superficial frostbite will redd on and become painful as circulation resumes in the area. Blisters are likely to form within 24 hours.
While a frostbite injury is healing, do the following: - Avoid infection by leaving the blisters alone. - Watch for signs of infection such as redness, swelling, fever, oozing pus, and red streaks on skin. - Take all prescribed medications. - Don't expose the affected area to cold temperatures until cleared to do so by a physician. Frostbite occurs when skin tissue and blood vessels are damaged due to over exposure to freezing temperatures. Frostbite occurs in three stages which are frost nip, superficial, and deep frostbite.
Frost bite can become infected and may result in amputation, or in some cases, a disease that can lead to death. It is therefore crucial to respond in a manner that is in correlation with the listed steps of dos and don " ts because it may help save a victim's body part, or even his life.
