Which is the most correct way to apply ice?

Ice should be done in stages, at least 30 minutes or more, it is important that each time does not exceed 15 to 20 minutes, ice for too long will cause local blood vessels to constrict excessively and cause frostbite, and even for peripheral vascular lesions, necrosis, severe cases need to be amputated. The ice compress on the joints should be covered with soft, milk capsules with crushed ice cubes (half each) and gently covered to cool evenly. Do not take out ice packs with a hard ice layer, not only can not effectively apply ice, but will cause frostbite at the joint carina.

Warm compresses can increase local blood circulation, help remove lactic acid build-up or inflammatory substances caused by muscle fatigue, and therefore also have an anti-inflammatory effect. Warmth makes people feel comfortable, lazy, and stretches the skin, so it has a considerable relief effect on chronic and long-term tendonitis, such as low back pain, neck and shoulder syndrome, overuse tendonitis, fatigue, local soreness, and even insomnia.

The hot compress should not exceed 50 degrees, and the heat transfer of water is far better and uniform than that of air. Damp heat, such as hot towels, shower heads to make hot water or spa, bath, than dry heat, such as electric blankets, warm packets, more able to penetrate into the deep part, but also safer will not burn.

Some sports injuries do not go away after a long period of swelling, such as improper ankle sprains, you can use "hot and cold alternating hydrotherapy"; Soak in hot water at 38 to 45 degrees for 4 to 6 minutes, then immediately soak in cold water at 10 to 15 degrees for 2 to 3 minutes, alternate five times (the last time is hot water), and then tie an elastic bandage, do it two or three times a day, most of them will be effective within two weeks.

This is the most correct way to apply ice: for 48 to 36 hours after the injury, apply ice to the area where the pain or swelling has occurred every 3 to 4 hours for 20 to 30 minutes.

1. Location: the location where pain or swelling occurs.

2. Material: Ice water mixture is the best, followed by popsicles, chemical ice packs, cold water, etc.

4. Frequency: Once every 3-4 hours is a common method.

5. Treatment: Generally used within 48-36 hours after injury.

Notes:1. Ice should be done in stages, at least 30 minutes or more, the important thing is not more than 15 to 20 minutes each time, too long ice will cause excessive constriction of local blood vessels and cause frostbite, and even peripheral vascular lesions, resulting in necrosis, severe cases must be amputated.

2. The ice compress on the joints must be gently covered with a soft plastic bag with water (half of each) with crushed ice cubes to cool down evenly; Do not take out ice packs with a hard ice layer, not only can not effectively apply ice, but will cause frostbite at the joint carina.

The correct method of applying ice packs requires the selection of the correct ice pack, the choice of location and timing, the frequency of ice packs, and the duration of ice packs. The correct method of applying ice is:

1. Correct selection of ice packs.

Hospitals and pharmacies generally have specialized medical ice packs**. But most people don't have these at home, so in case of emergency, you can make your own ice-water mixture, not pure ice. Find a plastic bag that is not broken, about 1:1 according to the ratio of ice to water

2 Around 1:3, place the ice-water mixture in a plastic bag.

Note: The plastic bag should not be overfilled, generally about 1 2 2 3, and then tie the mouth of the plastic bag tightly, that is, to make ice packs.

2. Correct ice placement and timing.

Ice should be started immediately after the injury, and the sooner the better. The ice application is centered on the most obvious areas of pain, swelling, and heat, and the ice can be moved appropriately to achieve all-round ice compression. In addition, do not put ice packs or even ice cubes in direct contact with ** ice compresses, and should protect objects with towels in between.

3. Correct frequency of ice.

Ice should be applied every 2 3 hours, and if the swelling, pain, and fever are obvious, ice can be applied every 1 2 hours, and ice can be applied 3-4 times a day. The more often ice is used, the more likely it is to be effective in reducing inflammation.

4. Correct duration of ice.

Keep the duration of each ice pack to 15 to 20 minutes, and remember that the ice time should not be too long, as it will lead to reflex dilation of blood vessels, which will be counterproductive and aggravate the inflammatory response. It's not that the longer the ice, the better. Apply ice for a short period of time to constrict blood vessels and reduce inflammation and exudation.

If it looks red, it's a warning sign, and if you feel some numbness, it's time to stop applying ice. Ice packs should be soft, and do not use hard ice packs, which will not only not be effective in applying ice, but will cause frostbite in the joint protrusions.

Notes:

1. Avoid pressing ice cubes and ice packs under your body when applying ice, and replace ice packs and towels frequently; And pay attention to the time when applying ice, if chilblains or systemic reactions occur, the ice should be stopped immediately, the light case should be kept warm, and the heavy case should be treated according to the doctor's instructions.

2. Use ice cubes for cold compresses, and the ice cubes should not be in direct contact with ** when cold compresses, so wrap the ice cubes with a towel or water bag to surround the sprained parts as much as possible.

The correct way to apply ice is to choose the right ice application equipment, determine the cold compress area, grasp the best time to apply ice and grasp the time to apply ice. The specific explanation is as follows:

1. Choose the right ice equipment.

Ice packs can be used for ice packs, ice towels and wrapped ice cubes, ice packs should be used to ensure that the chemical refrigeration is intact and there is no leakage, and ice towels should be disinfected and sterilized before use; Ice cubes should be separated by a waterproof bag or towel to prevent the melted water from infecting the affected area.

2. Determine the cold compress site.

It is usually applied to the area where pain or swelling occurs; If you have a high fever, you can apply ice packs to the forehead, neck, armpits, and groin.

3. The best time to apply ice.

Ice is the most common form of cold therapy and reduces limb swelling, and the microcirculatory disorders and the resulting tissue damage are not evident in the first 24 hours after trauma. So apply ice as soon as possible and for a while.

4. Grasp the time of ice.

Usually 20-30 minutes per session. (This is usually the time it takes for the ice to melt.) ）

Notes:

1. Avoid pressing ice cubes and ice packs under your body when applying ice, and replace ice packs and towels frequently;

2. Pay attention to the time when applying ice, if chilblains or systemic reactions occur, you should stop the ice immediately, keep warm in the light case, and deal with it according to the doctor's instructions.

1. Ice packs, ice towels and wrapped ice cubes can be used for ice packs, and the ice packs should be used to ensure that the chemical refrigeration is intact and there is no leakage, and the ice towels should be disinfected and sterilized before use; Ice cubes should be separated by a waterproof bag or towel to prevent the melted water from infecting the affected area.

2. Place an ice pack on the affected area and apply a cold compress, usually to the area where pain or swelling occurs; If you have a high fever, you can apply ice packs to the forehead, neck, armpits, and groin.

3. Ice is the most common cold therapy method, which can reduce limb swelling, the best ice time is within 24 hours after the injury, and the longest can not exceed 48 hours, ice is the best effect within 24 hours, which can effectively inhibit blood circulation, reduce local metabolism of the face, and reduce the cold pain and swelling of the body.

4. Ice time is 20-30 minutes each time, if you need to apply ice for a long time, at least 30-60 minutes apart each time, add a cloth bag outside the ice pack, often observe the local ** ice compress, and deal with it in time to prevent tissue necrosis.

1. The surface of the red, swollen, hot and painful surface of the ice compress is placed in the sail cavity, if the range is relatively large, the ice pack can be moved slowly, and the towel should be protected in the middle of the ice compress.

2. The time of ice should not be too long, short-term ice can constrict blood vessels and reduce inflammation and exudation, but long-term ice may lead to reflex dilation of blood vessels, which will aggravate inflammation.

3. The sedan car ride time of the ice compress is generally 20-30 minutes, which can be applied 3-4 times a day, or 10 minutes each time, and the rest is 10 minutes, a total of 3 to 4 times.

First of all, the principle of ice is as follows:

Reduces and slows down the release of histamine and reduces tissue sensitivity to pain; Reduces exudation and swelling of microcirculation and surrounding tissues; Reduces the action of vascular endothelial cells and the formation of thrombosis; Reduces the release of oxygen radicals and more.

There are also studies that show that in the first 24 hours after trauma, microcirculatory disorders and the response to tissue damage secondary to them are not significant. So apply ice as soon as possible and for a while.

In this way, early and reasonable ice can achieve the goal of reducing the degree of tissue trauma and speeding up tissue repair.
