Generally, frostbite is divided into four degrees, what are the symptoms?

When winter comes, some people get frostbite because of the cold and wet weather. After being frostbitten, the following symptoms generally appear, such as redness, swelling and congestion in the frozen area**, or edema, severe pain, etc.

1. Symptoms of first-degree frostbite. The first degree of frostbite is mild, and the common "frostbite" is a degree of frostbite, and the place where the frostbite is damaged is on the surface of the first degree, and the frostbitten part will show symptoms of redness, swelling and congestion, and the person who is frostbitten will also feel fever.

Itchy, burning, painful. These symptoms will generally disappear after a few days, and after the frost is cured, except for some peeling on the surface of **, there will generally be no scarring.

Second, second-degree frostbite symptoms. Second-degree frostbite hurts the superficial dermis, and after frostbite, in addition to the symptoms of redness and swelling, there will also be blisters in the market.

Bloody fluid can be seen in the blisters, ** there will be symptoms of edema, there will be severe pain, and ** the feeling will be relatively dull, not much sensation.

3. Symptoms of third-degree frostbite. Third-degree frostbite will hurt the whole thickness of the **, so ** will appear black or purple-brown color, and the very severe pain of frostbite will also be lost, that is, I don't know the pain. This kind of frostbite is very serious, even if it is not easy to scar after the injury, it is easy to leave scars, and there will be long-term allergies or pain.

Fourth, fourth-degree frostbite symptoms. Fourth-degree frostbite injures ** as well as subcutaneous tissues.

Or the muscles and even the bones can be frostbitten, which can lead to necrosis, loss of sensation, and scarring even if healed.

Exist. Therefore, the problem of frostbite should not be underestimated, and it should be carried out when it is found that it is frostbitten, such as quickly getting out of the cold environment to prevent continued freezing, or going to a place with a relatively high room temperature, or applying some frostbite cream, or taking some blood circulation and stasis.

and other drugs, etc.

Generally, frostbite includes: first-degree frostbite is **superficial frostbite, second-degree frostbite is full-thickness frostbite, third-degree frostbite is **and subcutaneous tissue is frostbite, fourth-degree frostbite is **, subcutaneous tissues, muscles or bones are frostbitten.

First-degree frostbite is the lightest, that is, the common "chilblains", damaged in the epidermal layer, the frozen part is red, swollen and congested, and the symptoms disappear after a few days, except for the epidermis shedding, there is no scar. Second-degree frostbite and superficial dermis, in addition to redness and swelling after injury, accompanied by blisters, the blisters can be bloody fluid, deep edema, severe pain, ** dullness.

Third-degree frostbite injury and ** full-thickness injury, black or purple-brown, loss of pain. The injury does not heal easily, and in addition to scarring, there may be long-term hyperesthesia or pain.

Fourth-degree frostbite injures **, subcutaneous tissues, muscles, and even bones, necrosis, loss of sensation, and scarring after healing.

Frostbite is caused by the cold acting on the human body under certain conditions, causing systemic or local damage, usually the affected area stings and gradually numbness, paleness and other symptoms.

Local frostbite often occurs in ** and hands, feet, fingers, toes, ears, nose, etc.

Frostbite is graded in four degrees.

Degree: Involving the epidermal layer, **redness, swelling and congestion, heat, itching, burning, except for epidermal peeling off after healing, leaving no scar.

Degree: Involves the superficial dermis, redness and swelling with blisters, deep edema, severe pain, and sluggishness.

Degree: Involving ** full layer, black or purple-brown, pain and feeling of inclusion, not easy to heal after injury, and scarring.

Degree: Involvement**, subcutaneous tissues and muscles, and even bones, necrosis, loss of sensation, and scarring after healing.

Prevention of chilblains: The best way is to keep warm, avoid exposure to cold environments, enhance nutrition, keep exercising, improve physical fitness, improve blood circulation in the body, and improve the body's cold tolerance.

Answer: Pro, we will be happy to answer for you. Dogs may experience symptoms such as listlessness, sneezing, and a large amount of watery discharge from their nose, while the dog's ears and body temperature will decrease, and the tip of the nose will also become cold. The owner should use a blanket or electric blanket to keep the dog warm in time, and feed the dog some warm water, otherwise the dog may be in shock and die due to the low temperature.

Dear, dogs exposed to sub-zero degrees Celsius can get frostbite, especially in windy conditions. Check your dog's feet, ears and tail, which may be pale or cold and unresponsive. Apply a towel to gently stroke it.

Treatment of frostbite is to warm the frostbitten area of the dog with warm water (32). It can be thawed in 10 minutes, ** may be red. Keep your dog warm until the veterinarian arrives.

Frostbite is a lesion caused by the impaired local blood circulation after the surface of the body is damaged by low temperature, which is generally divided into local frostbite and generalized frostbite. Frostbite mostly occurs on fingers, toes, earlobes, noses, etc., and appears red, itchy, red and swollen. The lesion is superficial, producing reddish-purple spots, local itching, stinging, and paresthesia for frostbite; If the injury reaches the deep level, the local redness and swelling are more obvious, blisters appear, and the serum or bloody fluid is inside, and the pain is more severe, but the person with dull sensation is frostbite.

If there are chills, cold, whitish, cyanotic limbs, followed by numbness, weakness of limbs, fatigue, sluggishness, confusion, coma, arrhythmia, shock, and freezing, it is generalized frostbite.

The principle of frostbite should be the combination of traditional Chinese and Western medicine to prevent or reduce disability and preserve the function of viable tissues and affected limbs to the greatest extent.
