Quick Answer
WARNING SIGNS OF SEVERE FROSTBITE INCLUDE NUMBNESS, PARALYSIS, AND BLANCHING OF SKIN IN A MATTER OF MINUTES. IF LEFT UNATTENDED, FROSTBITE CAN QUICKLY PROGRESS TO BLOOD FLOW RESTRICTION, CAUSING TISSUE DAMAGE AND PERMANENT DISABILITY.
Recognizing Frostbite Warning Signs
Frostbite warning signs can be divided into three main stages:
- Stage 1 (frostnip): The skin feels numb, cool, or prickling and may appear pale or flushed.
- Stage 2 (superficial frostbite): The skin becomes numb, waxy, and pale with possible pinpoint bleeding when the skin is broken.
- Stage 3 (deep frostbite): The skin appears white and waxy, and may be accompanied by a lack of blood flow detectable by the touch or by a lack of sensation.
Preventing and Treating Frostbite
Preventing frostbite requires dressing in layers, staying dry, and limiting exposure to cold. Treatment of frostbite starts with the removal of any constrictive items, followed by rapid rewarming of the affected area in warm water (less than 104 degrees Fahrenheit) for 20-30 minutes or until sensation returns. Do not use hot water, heat lamps, or heating pads as they can cause further damage.
Assessing Frostbite Severity
To assess the severity of frostbite, check for the depth and area of tissue damage, and monitor for signs of infection, including redness, swelling, and foul odor. Monitor for the return of sensation and blood flow to the affected area. If the individual experiences numbness or tingling after rewarming, consult medical attention promptly.
