Rinse with cold water immediately. Only after cooling can you carefully take off your close-fitting clothes to avoid tearing and scalding blisters. The purpose of cold water washing is to relieve pain, reduce exudation and swelling, thus avoiding or reducing the formation of blisters. The washing time is about half an hour or more, so as not to feel pain when stopping washing. The general water temperature is around 20℃. Avoid using ice water to avoid frostbite. If you burn your fingers, you can also take a bath with cold water. Cold compress can be used on the face and other parts where you can't wash your face or take a bath. After cold water treatment, dry the wound, then apply some ointment drugs such as blue oil hydrocarbon and green ointment thinly, and then wrap it properly for 1~2 days to prevent blisters. But you can only show your face without clothes. If blisters form, you can use a sterile syringe to suck or cut a small hole to drain water. If the blister is broken, dry it with a sterile cotton ball and keep it dry, so as not to make the water accumulate into blocks. If you burn 1~2 fingers, you can also use a simple method-soak in soy sauce, that is, invade your fingers with a small cup of soy sauce, and the pain can be relieved in about half an hour without blisters. Do not apply purple liquid or mercuric chloride after scald, so as not to affect the observation of wound changes after injury. Large or severe burns should be sent to the hospital immediately after general emergency care at home. Pay attention to the cleanliness and dryness of the wound surface for skin burns, and avoid soaking again after cold water washing. After about 2~3 days, the wound can be dried. There is no need to take medicine at this time. It takes about 10 days to remove the scab and recover. If it doesn't heal at that time, please ask a doctor to see if it is caused by deep burns or infection. Antibiotics are generally not used after scalding. If 1~2 days later, the wound is still red, swollen and painful, then infection is suspected and can be treated under the guidance of a doctor to avoid unnecessary pain. Flushing, soaking, covering and delivering are the five steps of first aid for burns. Flush quickly and massively at the first time, at least for half an hour, to reduce the time that heat stays in the wound. Then, take off your clothes, then soak the affected area with cold water, cover it, and send it to the hospital for emergency treatment. The most important thing in the hospital is to have tetanus, disinfect the wound and apply burn ointment. Patients often ask: Do you want to puncture the blisters? In fact, this aspect also depends on the doctor's clinical judgment, especially in some places where big blisters and joints are easy to break, doctors will use empty needles to pull out blisters. If it is a shallow second-degree wound, it usually heals within two weeks. If there is no infection, there is generally no scar left. The patient goes to the hospital for dressing change once every two days, and it is ok to use antibiotic ointment. Generally, scald ointment has strong permeability and is recommended for deep wounds. During the two or three weeks of recovery, be careful not to let the wound get wet with water. If the affected part is the foot, after seeing the doctor for a week, advise the patient to raise his foot and reduce walking, so that it will be less painful. If the wound hurts, you can use some painkillers or use a little ice to reduce the temperature of the wound to reduce the pain. Can burns leave scars? In fact, the most important thing between burns and scars is the healing time. If it can be cured within two weeks, 70% will not leave scars. If it takes more than three weeks, most of them will still have scars. So the third stage is to face burn scars. There are two main levels of scald scars: the first is color, and the second is lumps and bulges. If there is only color, two or three months after burn, it is recommended that patients wear sunscreen clothes or long sleeves, and do not let sunlight and ultraviolet rays directly irradiate the affected area. Then there are raised scars. If there are raised scars, patients will be advised to use elastic clothes. At present, the most effective method for scalding patients is to use the pressure of elastic clothing for six months to one year, which can minimize the degree of scar. After these three stages of treatment, scars can usually be treated to the best condition. Your current situation is to prevent and treat infections. If you want to wash it, it is generally better to use normal saline.
