How to save people who are about to freeze to death? How can you freeze yourself to death

If you can still feel the cold, then don't worry, you will still be alive. People who are frozen need a warm space and hot soup.

Start with a cup of hot tea. There's another warm space, hehe. Finish.

First aid and ** principle:

Quickly get out of the cold environment to prevent further freezing;

Hurry up and rewarm quickly as soon as possible;

Topical application of frostbite cream;

Improves local microcirculation;

anti-shock, anti-infection and warmth;

The application of internal drugs such as blood circulation and blood stasis removal;

If the second and third degree frostbite cannot be distinguished, it will be treated as third-degree frostbite**;

Surgical management of frostbite should minimize disability and preserve viable limb function to the greatest extent.

2. Rapid rewarming: After getting the wounded out of the cold environment as soon as possible, if possible, they should be immediately rewarmed with warm water, and escorted under the condition of sufficient warmth after rewarming. If there is no rapid rewarming condition, the escort should be carried out as soon as possible, and attention should be paid to keeping warm during the escort to prevent trauma.

Rapid rewarming with warm water should be performed immediately upon arrival at the medical unit. Especially for those whose treatment is still frozen.

Second, third, and full-thickness burns, rapid rewarming is always a significant and critical measure.

Specific method: soak the frozen limb in warm water at 42 degrees Celsius (not too high) until the frozen area turns red, especially the nail bed flushes and the tissue becomes soft, and the time should not be too long. For facial frostbite, a towel can be soaked in warm water at 42 degrees Celsius and a local warm compress can be applied.

In the absence of warm water, the frozen limb can be immediately placed on a warm part of the body of the self or the rescuer, such as the armpit, abdomen, or chest, for the purpose of rewarming. During treatment, it is strictly forbidden to roast, snow rub, soak in cold water or beat the affected part violently.

3 To improve local microcirculation, low-molecular-weight (molecular weight below 40,000) dextran can be applied in the early stage of third-degree frostbite, intravenous infusion, and daily administration of 500 1000 ml for 7 10 days to reduce blood viscosity and improve microcirculation. Anticoagulants (eg, heparin) or vasodilators (papaverine, benzylaminezoline, etc.) may also be used as needed.

4 Local treatment.

1) Topical medication: apply topical ointment for frostbite immediately after rewarming, which can be appropriately thicker, and need to be applied between the fingers (toes), and bandaged with sterile dressings, and change dressings 1 2 times a day, with a small area.

First- and second-degree frostbite can be bandaged, but pay attention to keeping warm. The frostbite creams that can be used are nitrofuracillin cream: nitrofuracilin, codipine cream: nitrofuracilin, dextran cream, etc.

2) The treatment of blisters should be to aspirate the blister fluid under sterile conditions, and if the blisters are large, they can also be drained through a low incision.

3) For the treatment of infected wounds and necrotic scabs, the infected wounds should be drained in time to prevent pus under the scabs, and the necrotic scabs should be eaten and removed in time.

4) Timely removal of necrotic scabs, and skin grafting as soon as possible after the granulation wound is fresh to eliminate the wound. After the early ** necrosis forms a dry scab, it is often difficult to judge the ability of deep tissue life, sometimes it seems that the extremities have been necrotic, but after the scab is removed, the granulation wound is exposed (indicating that the deep tissue is not necrosis), and it heals after skin grafting. Therefore, a cautious attitude should be taken towards amputation after frostbite, and it is generally believed that it separates and falls off on its own, and viable tissue is preserved as much as possible, and arteriography can be performed if necessary to understand the blood circulation of the acral ends.

5 Prevention of infection, severe frostbite should be oral or injection of antibiotics: tetanus prophylaxis injection is routinely administered.

1.Put yourself in a low temperature environment to bring your body temperature below normal until you die.

2.Immerse yourself in ice water to bring your body temperature below normal until you die.

3.Place yourself in the refrigerator and bring your body temperature below normal until you die.

4.Place yourself in the freezer and bring your body temperature below normal until you die.

The existence of each life has the meaning of his existence, and I hope that the subject can get through difficult times, cherish life, and love life.

In winter, because of the cold weather, many people have frozen their hands and feet when they go out, especially those who go out all year round, so how to give first aid when people are frozen? Will there be sequelae in rescuing a frozen person? I'll take a look with you below.

How to give first aid when people are frozen is a question that many people have in winter, but in fact, there are quite a lot of methods. First, remove wet clothing, wrap it in a dry blanket and bedding, and warm it with a hot water bottle but avoid burns**. If the anal temperature is less than 30 degrees Celsius, a full-body warm bath should be done to gradually raise the water temperature to 40 to 42 degrees Celsius for 10 to 30 minutes.

If the body temperature rises above 28 degrees Celsius and the heartbeat is still not restored, cardiopulmonary resuscitation should be performed, and active resuscitation must be obtained before obtaining definite evidence of death!

How long it takes for a person to recover after freezing depends mainly on how cold you are. Mild symptoms of freezing include headache, restlessness, fatigue, forgetfulness, chills, polyuria, and incomplete intestinal obstruction. Moderate symptoms of freezing include apathy, speech disturbances, behavioral abnormalities, lethargy or coma, and multi-organ dysfunction or failure.

Severe freezing symptoms include drowsiness and a state of near death. As for the recovery time, when the body temperature is less than 12 degrees Celsius, the limbs are red, swollen and painful after rewarming, and it takes weeks or months for nerve and muscle functions to recover, and physiotherapy can shorten the recovery time.

If a person is frozen, there are many examples at home and abroad, there is a certain chance that it can be rescued, but the probability of recovery is lower after a long time, it is recommended to send the patient to the nearest hospital as soon as possible, do relevant rescue measures, and increase the chance of survival.

Will there be sequelae of the frozen person is one of the most concerned issues nowadays, like this mainly depends on the condition of your frostbite, a group of moderate freezing, to severe freezing will leave some sequelae, especially some sequelae of residual limbs. The lighter the freezing, the easier it is, the smaller the chance of complications, the more serious the frostbite and the more sequelae there are.
