Quick emergency treatment when burns and scalds occur

Burns or scalds often occur in daily life. When faced with this situation, people often panic, yell, run to the hospital in a panic, or quickly apply soy sauce, alkali or salt to the wound surface. In fact, these practices often affect the treatment of wounds, and sometimes even worsen the condition. Because the heat has burned the skin after the burn, the heat invading the body will continue to penetrate into the deep layer, causing delayed damage to the deep tissue.

So, how to use the on-site facilities where burns or scalds occur to carry out scientific and reasonable early treatment of wounds to reduce the damage caused by burns?

Cold therapy Cold therapy is to rinse the injured limbs under running tap water or soak them in a large basin after the burn. If there is no tap water, the limbs can be immersed in well water or river water. Cold therapy can reduce local temperature, reduce wound pain, prevent continued thermal damage and reduce exudation and edema. The duration of cold therapy is mostly based on the fact that there is no more severe pain after the cold therapy is stopped, which is about 0.5 to 1 hour. The water temperature is generally 15 ~ 20 ℃, and those with conditions can put some ice cubes in the water to reduce the water temperature. Timely cold therapy can neutralize the residual heat invading the body, prevent the further penetration of heat, prevent the wound surface from deepening, and reduce the depth of tissue burns.

Cold therapy can also reduce edema. After burns, the skin capillaries expand rapidly, and the capillary permeability increases. A large amount of plasma-like substances leak out of the blood vessels to form edema or blisters. Cold therapy can cause the capillaries that expand due to high temperature to contract sharply and reduce plasma samples. Exudation of the substance reduces edema. Therefore, the sooner the cold treatment after burns, the better. Don't worry about bacteria in the water, and the burn wounds will be infected if they contact the raw water. Early cold treatment of the wound surface should be carried out without hesitation to minimize the damage. Although it can be effectively treated immediately, it sometimes misses the prime time for wound treatment, causing irreversible damage to the deep part of the wound.

Acid-base burns can cause severe deep burns. Although the acid and alkali can be neutralized, the neutralization reaction can generate heat, but will deepen the depth of the wound. When chemical burns on the head and face, first pay attention to the eyes to see if the cornea is damaged, and immediately rinse the wound with plenty of water.
