Winter trauma loves to haunt babies!

Chilblain is a localized inflammatory erythematous lesion caused by exposure to low temperatures above freezing and high humidity (wet and cold environment), which will heal itself after the climate warms up. To put it simply, in a cold and humid environment, the blood circulation in the human body is poor and frostbite will appear.

That is to say, when the body is in a low temperature and humid environment for a long time, the blood vessels on the surface of the human body will spasm, blood flow will decrease, tissues will be ischemic and hypoxic, and cells will be damaged. Fingers and toes with poor blood circulation are especially prone to frostbite.

In cold weather, babies are prone to frostbite, which is determined by climatic factors, physiological factors, clothing factors, etc.

Climate factors: Cold weather, including air humidity, air velocity and sudden weather changes, humidity and wind speed will affect the body's heat dissipation.

Physiological factors: The ratio of a baby's body surface area to body weight in kilograms is larger than that of an adult, which determines that the baby's skin dissipates heat quickly and consumes a lot of heat. A baby's skin is also more sensitive to temperature changes in the external environment than an adult's. When the temperature is lower than 10℃, the subcutaneous arterioles contract and the venous blood returns poorly, causing frostbite in babies. In addition, the water content of baby's skin tissue is higher than that of adults, which is also the reason why babies are prone to frostbite.

Clothing factors: Wearing tight shoes and socks, standing still for a long time, or soaking in cold water for a long time can all cause blood circulation disorders and lead to frostbite.

Why do some babies get frostbite every year?

Doctors point out that some babies suffer from frostbite every year. The reason is that their skin surface temperature is lower than that of other babies, and their peripheral circulation is worse than that of ordinary people. Malnutrition of some babies can also aggravate peripheral circulation disorders.

How to treat baby frostbite?

For those without ulceration: you can use some drugs to promote blood circulation, such as capsicum tincture, vitamin E ointment, 10% camphor ointment, and take vasodilators such as niacin orally when necessary. Special reminder: Remember to take the oral dose for your baby under the guidance of a doctor!

For those with ulcers: you can use some 5% boric acid ointment or erythromycin ointment.

In addition, mothers should not blindly use rubbing or hot water soaking to treat frostbite by themselves, because if the strength or temperature is not well controlled, it is easy to cause the baby's skin tissue to suffer a secondary blow or even infection. If there is no improvement after applying ointment, you should go to the hospital for treatment in time.
