Many burn scar patients are seen every day, most of them are children, and these scar growths obviously affect function and appearance severely. The patients’ expressions are painful, and as a doctor, I feel the same as they do. At the same time, I feel sorry for them, they could have been less miserable, if they had actively taken appropriate first aid measures, especially those who were scalded by hot rice and soup. And among these patients, the most were scalded by hot rice and soup, especially children. The temperature of hot water is only 100 degrees at most, and hot water burns do not leave such obvious scars if treated promptly. Today on the first aid treatment of burns, heat to cause injury requires two conditions one is a higher temperature, but last for a certain period of time, one without the other. If the temperature is very low such as 38 degrees even if a long time will not cause damage; in addition, even if the temperature is very high, if the duration is short enough will not cause damage. And even if the temperature is not very high, if it lasts long enough, it will also cause burns. I remember that there was once a patient who lost feeling in his fingers after electric shock injury, and once he ate a hot steamed bun, and his fingers were burned as a result. Since this patient could eat the bun, the temperature of the bun was not too high, and the reason why it caused a burn was because the heat lasted long enough. So the most important first aid measure after a burn is to cool down quickly and effectively in the shortest possible time. Cooling down can stop further damage on the one hand, and also stop the pain at the same time. The most practical and best cooling substance is cool water. After a burn, you should first soak the burned part in cool water or tap water for continuous flushing, or use a cold towel for wet compresses. If the clothing is soaked with hot liquid, the clothing should be taken off first, because if the clothing is not taken off, the heat of the clothing will continue to heat damage the skin. Many parents worry that taking off clothing will tear off the skin of the blisters, in fact, this worry is unnecessary, for two reasons, one of these blisters have been necrotic even if they remain will not survive; if the blisters are large, the burn doctor will remove these skins in the debridement, which will remove the necrotic tissue under the blisters or dressing. So you should decisively remove the soaked clothing and not worry about tearing off the skin. After the emergency treatment, the next step should be to seek medical attention as soon as possible, and continue to cool down on the way to the doctor, so as to reduce the pain. The most wrong thing to do is to go to the hospital after a burn without any cooling treatment, especially if the clothing is soaked with hot liquid. From the burn to the doctor, even if your home lives across the street from the hospital, the process will take more than 10 minutes, and the heat on the clothing is enough to burn the skin to death. To use an inappropriate analogy, you put the lamb slices in a less hot hot pot for 10 minutes, is not the meat also cooked. Another wrong practice is to apply various ointments and other things on your own, the burn doctor is to determine the depth of the burn through the skin color, so as to determine the treatment plan, these things may affect the color of the skin, interfering with the doctor’s judgment. In short, after the burns, the most important thing is the first time to cool down, until the hospital is already too late.
