How Long Should Frostbite Last
2-3 days after: The initial thermal cold injury is when tissues can be black. Still even seemingly damaged tissues may survive. Tissue survival is a main difference between a medium deep frostbite and a severe frostbite. But both can be black after a few days. This is why most doctors will tell you to let the tissue "demarcate" before doing anything. The tissue is watched as healing takes place.See 1 more doctor answer
Can take a long time: Frostbite injuries can heal very slowly. Often the final amount of tissue lost is less that one would predict initially. The general rule is: "injured in january, operated on in july.".
Varies on severity: Of compromise of the blood supply. Individuals with vaso-occlusive disease such as diabetes may be prone to more extensive disease and complications.
Depends on size/area: Frostbite occurs when the cold injury causes the tissue to die from cold exposure or the vascular supply to thrombose. Typically extremities are more vulnerable such as the tips of fingers or nose. Larger areas with better blood supply may be able to tolerate cold exposure for longer periods due to their ability to be closer in proximity to the core and maintain circulation.
Difficult question: It depends on whether it is wet or dry cold, what the outside temperature is and what part of the body is exposed. Mostly frostbite occurs on the hands or feet. The colder the outside temperature the more rapid the onset. Also relates to the type of protective clothing. It can be just a few minutes or longer of exposure.See 1 more doctor answer
Long Time: It can take weeks to months to fully recover from frostbite. How long depends on how bad the frost bite was and how much tissue damage occured. Watchful waiting is best as there is no good way to tell how much tissue was damaged early on in the recovery. If blisters or scabs have formed, let them heal on there own. Hands may be sensitive for a long time after frostbite.
Wound care: Protect injured part and keep warm and watch for signs of tissue death or infection. Gently cleansing with a mild soap (such as cetaphil) twice a day with elevation are advised for 7-10 days while you monitor the status of tissue viability. This tissue may have compromised vascularity which may impair delivery of antibiotics to the area. Topical as well as systemic antibiotics prescribed by md.
Various factors: General health, baseline circulation, smoking status, core temperature, improper or too tight clothing, nerve issues, metabolic issues, wind chill, wetness, use of beta blockers all affect the time frame. Most important if you are getting frostbite, and are not in a secure location avoid rewarming true frostbite and then refreezing again. Do not wash hands in hot water. Do not drink or smoke.
Frostbie: You do not catch a cold by being exposed to cold temperatures. A virus causes it, not the cold. Developing a frostbite is irrelative to the degree of the temperature but the colder it is, the shorter the time to develop it. Some individuals are more prone to developing it even in not too cold temperatures, especially if protective clothing and gloves are not worn.
Is it possible, if placed on the skin for a prolonged period of time, to get frostbite from snow?
Yes: Frostbite can occur w/ exposure to very cold temperatures (esp. W/ wind) and snow in as little as 3-5 minutes... Your question is somewhat confusing, however, w/ your reference to isolated snow exposure. See your physician immediately or go to er if you think you are suffering from frostbite. ..
My uncle had bad frostbite on his leg. Because it took so long to be treated, they say it might turn into gangrene. How long would it take to turn?
Fairly fast: Look for hard spots or dark areas. Usually at the very ends of the extremities like at the tip of the toes.
For hypothermia and frostbite, when do they amputate your limbs and how long does it take for them to know?
Requires an exam: Mild frostbite heals well, even blistering can heal without disability. Severe frostbite usually takes days to demarkate, and sometimes weeks. As long as it is not infected, the injury can be treated supportively until the determination is made. If infection occurs, then the issue becomes more critical.See 1 more doctor answer
I had frostbite last winter on my toe. This year as soon as it got cold I got a black spot on my toe that hurts when my foot gets cold?
Damage: You have some residual damage to the micro-circulation to the toe. I hope is goes away when you are able to get it warmed up. If the dark spot persists you should see your provider.
Injury to be managed: Frostbite happens when the body part affected gets frozen. Your body has to heal up from the injury. If the frostbite is mild, prognosis is very good. If it is severe, you can sometimes lose the affected body part. Seek medical treatment asap, and educate yourself in frostbite prevention (not enough room here to go into details).See 1 more doctor answer
