Low temperature burn refers to the damage caused by skin contact with low temperature. Common low-temperature burns include freezing burns and liquid nitrogen burns. The purpose of treating low-temperature burns is to relieve pain, prevent infection and promote wound healing. The following are the steps to treat low-temperature burns:

1. Leave the low-temperature environment immediately: In case of low-temperature burns, the first step is to leave the low-temperature environment quickly to avoid continuous freezing. If it is frostbite, keep away from cold sources and avoid low temperature. If it is a liquid nitrogen burn, immediately put the injured part into warm water for washing.

2. Protect the wound: Cover the low-temperature burn with a clean dry cloth to avoid dehydration and secondary infection of the wound. Don't touch or rub the wound, so as not to cause more harm.

3. Relieve pain: Low-temperature burns may cause pain and discomfort. Over-the-counter painkillers, such as ibuprofen or acetaminophen, can be used to help relieve pain. But follow the correct dosage and usage.

4. Warm water washing: Wash low-temperature burns with warm water, and the temperature should not be too high. When washing, you can gently massage the surrounding healthy skin with your fingers to help blood circulation and recovery. The rinsing time is about 20 minutes.

5. Don't bake the wound with hot water or warm air: Never heat the low-temperature burn with hot water, warm air or other high-temperature substances, so as not to cause more damage.

6. Use antibacterial ointment: After cleaning, you can apply antibacterial ointment to prevent infection. Choose special antibacterial ointment for burns, such as erythromycin ointment or silver ointment.

7. Use dressing: According to the size and severity of the wound, use appropriate dressing to protect the wound. Generally speaking, transparent dressing or wound dressing can be used for shallow hypothermia burns. If the wound is very big or serious, it is recommended to seek medical help.

8. Avoid irritation and touch: Avoid wearing tight clothes, squeezing the wound or touching the wound with irritating substances to avoid aggravating the injury.

9. Observe the wound: observe the low-temperature burn regularly. If you have symptoms such as redness, exudation, fever and obvious pain, you should seek medical advice promptly.

In short, for low-temperature burns, it is the key step to leave the low-temperature environment immediately, rinse with warm water, protect the wound surface and avoid irritation and infection. If the burn is serious, it is recommended to seek medical treatment in time for further treatment.
