Takes medicines called beta-blockers\u003cbr\u003e2. Has poor blood supply to the legs\u003cbr\u003e3. Smoke\u003cbr\u003e4. Has diabetes\u003cbr\u003e5. Has Raynaud syndrome\u003cbr\u003eNormally the blood transports oxygen to all parts of the body so that the body tissues are maintained healthy.\u003cbr\u003eDuring a protective response when the body has exposure to extreme cold, the blood vessels narrow (constrict) so that blood (and oxygen) are transferred away from the extremities to the vital organs to keep the body alive.\u003cbr\u003eAfter a while, this inadequate blood supply and oxygen to the skin can begin to produce injury to the cells.\u003cbr\u003eIn the parts of the body involved by frostbite, the ice crystals form and cells and blood vessels become injured.\u003cbr\u003eBlood clots can also develop in small blood vessels which will decrease the possibility of blood and oxygen getting to the affected tissues.\u003cbr\u003eThe probability of frostbite is raised when the patient has longer exposure to the cold temperatures.\u003cbr\u003eRisk factors\u003cbr\u003eFrostbite is not frequent.\u003cbr\u003eFrostbite most often involves these groups of people:\u003cbr\u003e1. Soldiers.\u003cbr\u003e2. People who work outdoors in the cold.\u003cbr\u003e3. Homeless people.\u003cbr\u003e4. Winter outdoor sports people such as skiers and climbers.\u003cbr\u003e5. Alcohol may make the drunk less obvious to the cold and hence develop frostbite\u003cbr\u003eThe different degrees of frostbite\u003cbr\u003e1. First-degree frostbite just involves the epidermis.\u003cbr\u003e2. Second-degree frostbite may involve the epidermis and part of the dermis.\u003cbr\u003e3. Third-degree frostbite involves the epidermis, the dermis and the fatty tissue beneath the dermis.\u003cbr\u003e4. Fourth-degree frostbite occupies the entire thickness of the skin, the tissues that are below the skin, and also the deeper tissues such as muscles, tendons and bone.\u003cbr\u003eSymptoms of frostbite may be:\u003cbr\u003e1. Pins and needles feeling, followed by numbness\u003cbr\u003e2. Hard, pale, and cold skin that has been exposed to the cold for too long\u003cbr\u003e3. Aching, throbbing or lack of feeling in the affected area\u003cbr\u003e4. Red and extremely painful skin and muscle as the area thaws\u003cbr\u003eVery severe frostbite may cause:\u003cbr\u003e1. Blisters\u003cbr\u003e2. Gangrene (blackened, dead tissue)\u003cbr\u003e3. Damage to tendons, muscles, nerves, and bone\u003cbr\u003eDiagnosis:\u003cbr\u003eFrostbite is normally diagnosed by the normal features in someone who has been exposed to extreme, cold weather.\u003cbr\u003eScintigraphy and Bone Scans are occasionally used to evaluate the degree of frostbite and to determine how much tissue is injured\u003cbr\u003eTreatment\u003cbr\u003eThe basic first aid for frostbite injuries is:\u003cbr\u003e1. Shelter the person from the cold and move him or her to a warmer place.\u003cbr\u003e2. Change wet clothing for dry clothing.\u003cbr\u003e3. Keep the involved area air dry and wrapped\u003cbr\u003e4. Try to make sure that the person is re-hydrated.\u003cbr\u003eGive warm water to drink\u003cbr\u003eRapid re-warming can be done using heated water which should be kept at 37-39°C for 30 minutes\u003cbr\u003eRe-warming can be very painful, hence anti-inflammatory painkillers are also given\u003cbr\u003eSome 'clot-busting' medicines (thrombolytics) may be given in cases of deep frostbite to attempt to improve the blood supply to the involved area.\u003cbr\u003eSurgery is required to remove dead tissue -debridement of injured tissue and amputation of dead fingers or toes\u003c\/p\u003e\u003cp\u003eTABLE OF CONTENT\u003cbr\u003eIntroduction\u003cbr\u003eChapter 1 Frostbite\u003cbr\u003eChapter 2 Causes\u003cbr\u003eChapter 3 Symptoms\u003cbr\u003eChapter 4 Diagnosis\u003cbr\u003eChapter 5 Treatment\u003cbr\u003eChapter 6 Prognosis\u003cbr\u003eChapter 7 Cold Injury\u003cbr\u003eChapter 8 Hypothermia\u003cbr\u003eEpilogue\u003c\/p\u003e","brand":"Kenneth Kee","offers":[{"title":"Default Title","offer_id":47103696797936,"sku":"2940154607282","price":2.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940154607282_p0.jpg?v=1764072309","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940154607282","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
