Home burns are most commonly caused by hot water, hot objects (such as hot pots, hot water bags, hot pans, coal stoves), etc. There are also a few electric arc burns, summer motorcycle exhaust burns, etc. For the above injuries, the earliest treatment is to stop the ongoing process of their injury. It is easy to say, but many patients have a poor prognosis due to pain and panic after the injury, resulting in deepening of the trauma. We often say “cold therapy”, that is, the book said with 5-15 degrees cold water continuous flushing 20 minutes to half an hour. In fact, there is no specific limit to the temperature of cold water, and the time can be adjusted according to the specific situation. The principle of cold therapy is to bring down the elevated skin temperature, so that the heat does not penetrate deeper, and at the same time make the capillaries constrict, reducing the occurrence of blisters, as well as the pain-relieving effect. One of the key is the cooling process, such as cold water on the side, of course, you can rinse and soak, such as next to no cold water, as soon as possible to remove clothing is also very important. Some patients are scalded by hot water foot or lower extremity, insist to return to the room and then take off clothes, shoes and socks, the whole process up to a few minutes. However, these minutes are enough to cause the injury that should not be scarred to stay scarred, should not be implanted injuries implanted skin. Of course, when undressing, especially for pediatric scalding, care should be taken to protect the skin of the scalded area to avoid the blistering skin from falling off and being displaced. The shedding of blister skin can cause severe pain and can deepen the wound. Be cautious when applying your own medicine after cold therapy, and do not move out the set of kitchen ingredients (soy sauce, vinegar, pasta sauce, sugar, salt, alkali, etc.). The color of these things can affect the doctor’s judgment of the injury and increase pain during the cleaning process, while these high osmotic pressure objects can lead to dehydration of the injured cells, thus aggravating the injury. Do not use toothpaste either. Although toothpaste has a cooling sensation, it is difficult to clean and is not as good as cold therapy. Oily drugs can affect heat dissipation under certain circumstances and are detrimental to deep burns requiring scab preservation in exposed areas, so use with caution. Because most people lack experience in the diagnosis and treatment of burns, I suggest that patients should go to a specialist hospital as early as possible to avoid inappropriate treatment and the adverse consequences. Especially for patients with larger burns, the cold treatment time should be reduced and the injury should be covered with a clean cloth (such as a bed sheet) briefly for a timely visit to the hospital. The more serious patients may occur after the injury thirst, can be taken in small amounts of salt drinks without vomiting.
