TOPIC: What are the symptoms of frost-bite and how to avoid it?

What are the symptoms of frost-bite and how to avoid it? 7 years, 7 months ago #234

Can anyone tell what are the symptoms of frost-bite and how best to avoid it? Also what needs to be done immediately after frost-bite sets in? If unfortunately anyone here has witnessed it, would like to have first-hand information that can help everyone.

Thanks!

Hi,

Frostbite occurs when tissues freeze. This condition happens when you are exposed to temperatures below the freezing point of skin. Hypothermia is the condition of developing an abnormally low body temperature. Frostbite and hypothermia are both cold-related emergencies.

Frostbite occurs when the skin and body tissues are exposed to cold temperature for a prolonged period of time.

Symptoms of frostbite include:

Pins and needles feeling followed by numbness
Hard, pale, and cold skin that has been exposed to the cold for too long
The area may ache or throb.
Lack of sensation; you may not feel it if someone touches you there
As the area thaws, the flesh becomes red and very painful
Blisters
Gangrene (blackened, dead tissue)

Frostbite may affect any part of the body. The hands, feet, nose, and ears are the most vulnerable.

Basic DO's and DONT's

DO's

1. Shelter the person from the cold and move him or her to a warmer place. Remove any constricting jewelry and wet clothing.

2. If immediate care is not available, rewarming first aid may be given. Soak the affected areas in warm (never hot) water -- or repeatedly apply warm cloths to affected ears, nose, or cheeks -- for 20 to 30 minutes. The recommended water temperature is 104 to 108 degrees Fahrenheit. Keep circulating the water to aid the warming process. Severe burning pain, swelling, and color changes may occur during warming. Warming is complete when the skin is soft and sensation returns.

4. Apply dry, sterile dressings to the frostbitten areas. Put dressings between frostbitten fingers or toes to keep them separated.Move thawed areas as little as possible.

6. Refreezing of thawed extremities can cause more severe damage. Prevent refreezing by wrapping the thawed areas and keeping the person warm. If protection from refreezing cannot be guaranteed, it may be better to delay the initial rewarming process until a warm, safe location is reached.

7. If the frostbite is extensive, give warm drinks to the person in order to replace lost fluids.

DONT's

1. Do NOT thaw out a frostbitten area if it cannot be kept thawed. Refreezing may make tissue damage even worse.
2. Do NOT use direct dry heat (such as a radiator, campfire, heating pad, or hair dryer) to thaw the frostbitten areas. Direct heat can burn the tissues that are already damaged.
3.Do NOT rub or massage the affected area.
4.Do NOT disturb blisters on frostbitten skin.
