Frostbite occurs in late fall and early winter and is caused by overexposure of babies to cold and high humidity. The occurrence of frostbite is genetically related and has a physical susceptibility, which means that under the same conditions, some babies develop it and some do not. Frostbite is easily triggered when children are underdressed, spend too much time playing outside, do not change their gloves, shoes or socks in time when they are wet, or have poor blood circulation due to too tight clothes or shoes. Typically, the baby’s hands and feet are cold, and a purple-red edematous patch appears on the baby’s fingers, lateral edge of the palm, toes, heel, lateral edge of the foot or auricle. In severe cases, blisters or blood blisters may appear on the surface, and after rupture, vesicles or ulcers are formed, leaving pigmentation or scars after healing. Countermeasures: To treat frostbite, the main treatment is to invigorate blood circulation and remove blood stasis. You can use a decoction of 12 grams each of safflower, mulberry leaf and licorice to wash externally twice a day, and then apply frostbite cream topically. If the local skin breaks down, there is a possibility of secondary infection, and some antibiotic ointment, such as mupirocin ointment, can be used topically.
