What should I do?
Frostbite can be mild or severe.
STEP 1 Slight freezing
(1) Take the children back to the warm room,
(2) Take off your wet clothes carefully
Avoid getting wet clothes, socks, etc. absorbing more heat.
(3) Soaking in warm water
Soak the frozen part of the child in warm water at 38 ℃ for 20-30 minutes until the frozen part regains consciousness.
Limb perception may be temporarily lost after frostbite. Never let the child adjust the water temperature by himself to avoid further injury caused by too high a water temperature. It is recommended to use a thermometer to measure the water temperature.
(4) Send the child to the hospital,
If any of the following conditions occur after soaking in warm water, it is recommended to go to the hospital:
- Unable to regain consciousness; The frozen parts are purple, swollen, painful, etc.
2. Severe frostbite
(1) Call 120 or take the child to the hospital in time,
(2) Transfer children to a warm environment,
(3) Pre-processing
While waiting for an ambulance, necessary treatment can be carried out:
- [Thawing]: If conditions permit, It can be soaked in warm water at 38 ℃, If there is no warm water, you can use your body temperature. After thawing, Frostbite may cause burning sensation, swelling, Blisters or discoloration (red, purple, blue) may occur on the skin. Avoid skin damage on frostbitten parts: Use clean clothes and towels to separate toes or fingers to avoid infection caused by rubbing or moving to scratch the skin. Avoid freezing the [thawed] parts again: After thawing, be sure to keep warm. Use clean clothes to wrap the frostbitten parts to avoid freezing again and causing further damage.
Common Mistakes
1. Warm the fire or soak in hot water after mild frostbite (above 38 ℃)
Rapid change of heat and cold is one of the causes of chilblain. When the body is in a cold environment for a long time, peripheral blood vessels are contracting. Sudden contact with overheated hot water or warming fire will make capillaries suddenly relax and expand, and local blood circulation will immediately stagnate and chilblain will soon form.
2. Severe frostbite, thawing in cold environment
After severe frostbite, if [thawing] is carried out in a cold environment, the [thawing] limbs may freeze again, causing more serious injuries.
Therefore, severe frostbite is due to [thawing] in warm environments such as indoors.
How to prevent it?
Step 1 Keep warm
Try to keep the room temperature not lower than 10 ℃, when taking children out, should pay attention to the weak parts to keep warm. For children with sweaty hands and feet, once gloves, shoes and socks are found to have been soaked with sweat, they should be replaced immediately.
2. Pantyhose with appropriate tightness
Tight pants and socks will affect the circulation of lower limbs and are more prone to frostbite. When choosing children’s clothes, avoid too tight pants and socks.
