Life should pay attention to a long time hot water bag hot compress, stick baby warmer, physical therapy instrument physical therapy and other reasons leading to a kind of burns, medically known as low heat burns. It and high temperature open fire, boiling water and other burns caused by the difference is that, from the appearance of the scald area is not large, the epidermis is not as serious as the boiling water burns, but the scald surface is deeper, some can reach the bone, often resulting in tissue necrosis. The affected area of low heat burns is often found to be blistered and the opportunity for early cold therapy first aid is lost. Local drug exchange is the most conventional treatment for low heat burns, and it takes a long time to heal, often several months, and sometimes the necrotic tissue must be surgically removed and skin grafting or flap grafting must be done with autologous healthy tissue to be effective. Patients with a history of diabetes and long-term hormone consumption should pay more attention to avoid infection and more difficult healing of the wound. If hypothermia occurs in the lower extremities, patients need to brake and rest as much as possible and elevate the affected extremities (above the level of the heart) to promote healing. It is also recommended to consult a regular hospital as soon as possible. It has been observed that patients who go to the hospital immediately can heal about a month earlier than those who delay for about ten days. Do not use ointments, prescriptions or recipes in a self-righteous manner to avoid more serious consequences. Low heat burns often start out as a blister, after which the blister ruptures and the blister skin, along with the necrotic tissue underneath and some topical medication, forms a dry scab, or crust (jia), and waits for the scab to fall off after the new skin grows. This is often the process of exposure therapy and what the general population considers to be the process. There are many patients in the clinic who come in regularly for dressing changes and always ask me when the wound is going to crust over. Why isn’t it closed yet? In fact, bandage therapy is a moist therapy, which does not go through the process of crusting. Under the action of drugs, the necrotic tissue is gradually dissolved away and the granulation grows and epithelializes, which not only prevents infection, but also speeds up healing. Low heat burns tend to be deeper, and a focus on scab preservation can easily fail, and once the scab is dissolved, it can easily become infected and delay healing. Wound of low heat burns is recommended to wrap the scab lysis treatment. The above mentioned scabbing, what is scarring? Scarring is a pathological change in the new tissue after the wound heals, it will keep growing as the deep wound heals until about six months or even a year before it starts to stop growing and gradually shrink. Therefore, the “scar” will not fall off. Low heat burns are deep burns, which will leave different degrees of scarring after healing, so early scar prevention treatment is recommended.
