The most common question I get from patients in the emergency room is: What should I do immediately after being burned? This is also known as “cold therapy” in academic terms. The effect is twofold: first, it is very effective in relieving pain, and there is almost no more convenient and effective way to relieve pain; second, it can achieve the effect of reducing the depth of skin damage. The effect. After about half an hour, you can go to a hospital where you can get further medical attention. You can also use ice to cool down, but take care to prevent frostbite and do not make too long. Note: For small burns in life, the above methods are reasonable, but for special causes of burns or very serious burns with life-threatening conditions, such as a large area (more than the size of the patient’s own 15 palms for adults and more than the size of his own 5 palms for children), electrical burns, the presence of inhalation injuries, shock, coma, etc., the fastest first aid measures should be used immediately, such as calling an ambulance. For example, call an ambulance, etc., without delay. Some patients use toothpaste, soy sauce, soy sauce, vinegar, wine or alcohol, purple potion, red potion, incense ash topical application, or use all kinds of topical drugs that can be found at hand, etc. First, there is no exact efficacy, second increase the risk of contamination or even infection, and importantly, colored topicals can also seriously affect the doctor’s judgment and treatment of the wound. Therefore, these practices are not advocated. If it is a chemical injury, such as various acids or bases, please perform a flowing rinse with water at the first opportunity, especially for the eyes, and never delay! Rinse the skin well before going to the hospital for further treatment.
