After arm scald, if the scald area is not large, it is mainly to strengthen wound treatment. You can disinfect the wound with iodophor, release the blister, release the blister with a sterile syringe needle, or drain under the blister to keep the blister as much as possible, which can protect the wound. Then use silver zinc cream or antibacterial ointment such as Baiduobang and sulfadiazine silver ointment to dress and change the medicine. Change the dressing once every two days, and pay attention to raising the limbs and not sagging. Don't eat spicy food in your diet. After scald: 1. Wash the wound with cold water first, and then soak it in cold water for half an hour. Generally speaking, the earlier the soaking time, the lower the water temperature (not less than 5℃ to avoid frostbite), and the better the effect. But if the wound has been soaked, it should not be soaked to prevent infection. Two: Gently apply light salt water to the burn to diminish inflammation. Three: Put soy sauce or honey, egg white and ginger juice on the injured part, all of which are effective. Four: Cut some raw pears, or stick potatoes on the scalded parts, or apply fertilizer covers to relieve the pain. Five: After scalding children, boil thick juice with black beans and apply it to the affected area, which has certain effect. Six: Immediately after scalding hands and feet, pour alcohol into a basin or bucket and immerse the injured part in alcohol. If there is no alcohol, you can use white wine to relieve pain, eliminate redness and prevent foaming. If the wound is not in the easy-to-soak part, soak a piece of cotton wool in white wine, take it out and apply it to the wound. You can pour wine on the cotton wool at any time to prevent it from drying out. Good results can be obtained in a few hours. Seven: After the skin is scalded by oil or boiled water, it can be directly applied to the injured surface with wind oil essence, flower oil or vegetable oil (such as sesame oil). If the skin is not broken, it will usually stop the pain in 5 minutes.
