Frostbite

Frostbite of the auricles develops under the influence of low temperature. After a reflex spasm of the peripheral skin vessels, their paralytic expansion occurs, congestive hyperemia occurs with the release of the liquid part of the blood into the affected tissues, which leads to edema, the appearance of blisters and necrosis. There are 4 degrees of frostbite.

I degree - a temporary reversible circulatory disturbance in the skin of the auricle occurs, manifested by edema and cyanosis. Itching and burning are noted, which last for several days. Auricles remain hypersensitive to cold for a long time.

II degree - the skin is necrotic to the malpigian layer, blisters with transudate form.

III degree - total skin necrosis.

IV degree - necrosis of soft tissues and cartilage.

Edematous frostbitten sections of the auricles lose their sensitivity. With aseptic necrosis, the frostbitten parts are rejected, and with infection, moist gangrene develops. Rough cicatricial deformities that require plastic surgery remain.

Treatment. First aid for frostbite of the first degree consists in warming the auricles and protecting them from infection.
The shells are rubbed with a hand or soft cloth until redness. Rubbing with snow and a rough cloth should be avoided, and excessive force should be used so as not to injure the skin and cause infection. Wipe the skin with alcohol and apply an aseptic dressing. With general cooling, they give hot tea and a small dose of alcohol. When frostbite I degree, the victim does not need special treatment.

When frostbite II degree after skin treatment with alcohol, bubbles are pierced and an aseptic dressing is applied. When a ulcerative process occurs, UHF is used. With frostbite of the III and IV degree, a tetanus toxoid is administered. After determining the boundaries of tissue necrosis, necrectomy is performed on days 5-6. If there is abundant purulent discharge, apply dressings moistened with hypertonic sodium chloride solution or alcohol. They are changed daily. With the advent of granulations, dressings with Vishnevsky ointment, antibiotics, sulfonamides are used. At the same time use UHF and UV.

Frostbite

  1. Ear Massage
    Each movement here and further should be performed at least 8-10 times, first in one direction and then in another. The description will contain generalized formulations of the type “several times” or simply “first one way, then the other way”. This is done deliberately in order to ensure that the mechanical calculation of the number of repetitions does not absorb all your attention. The main thing where you need to direct your thoughts and
  2. Auricle frostbite
    Cause Prolonged exposure to low temperature in the ear. Symptoms Symptoms of mild frostbite of the auricle are redness, the formation of vascular spots. The skin is very sensitive and painfully sensitive to touch. The next degree of frostbite of the auricle is medium. It is characterized by swelling of the auricle and the formation of blisters. Symptoms III
  3. Auricles protruding
    Cause The hereditary structure of the auricle. Improper care in infancy. Symptoms Auricles deviate from the head by more than 30 °. First aid In this case, self-help is not possible. The protruding auricles in adolescents most often return to normal (aligned) by the end of puberty, since at this time the body grows and develops unevenly
  4. OAR SEA HEMATOMAS
    Hematoma - accumulation of blood in the cavity formed under the skin of the auricle as a result of mechanical damage (shock, compression, bite, etc.). Symptoms: ear size is increased, sharply limited, fluctuating swelling is visible on the inner or outer surface of the auricle, the cat is restless, shakes its head. With infection of the hematoma, suppuration occurs. Treatment: with fresh
  5. Frostbite
    Frostbite is damage caused by local overcooling of body tissues. The development of frostbite is promoted by: moist air and wind; alcohol intoxication, which removes the sensitivity of the skin to cold, increases heat loss due to the expansion of skin vessels; violation of local blood circulation with tight clothes and shoes. There are four degrees of frostbite: I - pale skin,

  7. Frostbite
    Frostbite - tissue damage when exposed to low temperatures, mainly when exposed to atmospheric air. The pathogenesis is based on a prolonged vascular spasm followed by thrombosis, which leads to trophic and necrotic disorders in the tissues. Contributing unfavorable physical factors: wind, humid air, duration of exposure to cold, poor body protection with clothing,

  9. Question 5. Frostbite
    - tissue damage caused by exposure to low temperatures. The factors contributing to O. include high air humidity, strong wind, tight shoes and clothes causing blood circulation disturbance, intoxication, a decrease in the general and local resistance of the body as a result of trauma, blood loss, vitamin deficiency, hunger, etc. Peripheral areas are usually frostbite.
  10. Frostbite
    Clinical characteristic of frostbite Frostbite is tissue damage that occurs when exposed to negative or low positive temperatures, which causes a perversion of neurovascular reactions, circulatory disorders, impaired tissue metabolism, the development of edema, and secondary tissue necrosis. Degree of frostbite I degree - pallor or blueness of the skin, marbling of the vascular
  11. Frostbite
    noses are quite common, there are four degrees of frostbite: • When swelling and blueness of the skin is noted after thawing; • blistering; • Necrosis of the skin and subcutaneous fat; • Necrosis of the skin and cartilage. First aid and treatment: it is necessary to restore blood circulation as soon as possible, for this, careful rubbing of the skin of the nose with alcohol, vodka,
  12. Frostbite
    This is tissue damage resulting from exposure to low temperatures. With the weakening of the body (illness, injury, prolonged exposure to wind and cold) frostbite can occur even at a temperature of +3 ... + 7 ° С. Distal extremities, ears, nose are more prone to frostbite. Degree of frostbite I degree - skin lesion in the form of various circulatory disorders. The skin is pale
  13. Frostbite
    Frostbite is the result of local exposure to cold. The leading factors in the pathogenesis of frostbite are prolonged vascular spasm with impaired microcirculation and thrombosis, which leads to trophic disorders. During frostbite, two periods are distinguished - latent and reactive. The latent period is the period of hypothermia. Depth of defeat is impossible to establish. You can suspect frostbite by
