Scalding is a first degree injury. Scalding only damages the surface layer of the skin, with slight redness and swelling, no blisters and obvious pain. You should immediately take off your clothes and socks, soak the wound in cold water for half an hour, and then wipe the wound with sesame oil and vegetable oil. Second-degree injuries and scalds are dermal injuries, local swelling and pain, and blisters of different sizes. For larger blisters, the edge of the blister can be broken with disinfectant needle to release water, and then wrapped with hot paste with moderate tightness. Third-degree injury, scald under the skin, fat, muscle and bone damage, gray or reddish brown. At this time, the wound should be bandaged with a clean cloth and sent to the hospital in time. Never apply purple liquid medicine or ointment to the wound, which will affect the observation and treatment of the disease. Patients with severe injuries and burns may go into shock or stop breathing and heartbeat during transfer, so artificial respiration or chest massage should be performed immediately. When the wounded are thirsty, a small amount of hot tea or light salt water can be used, and it is forbidden to drink a lot of boiled water in a short time, which will lead to brain edema of the wounded. The principle of fire, water, fire and scald treatment is to remove the heat source first, leave the scene quickly, and adopt various fire extinguishing methods, such as soaking in water, spraying water, rolling on the spot, immediately taking off wet clothes or cutting them open, spraying water, and soaking limbs in cold water until the pain disappears. You can also cover the wound with a wet towel or sheet and spray cold water on it. Don't burst the bubble. Fire and water burns can be divided into first-degree burns (erythema, skin redness with burning sensation), second-degree burns (blisters and blisters in the affected area) and third-degree burns (necrosis and skin peeling). For a small area of mild burns, they can be treated at home. After cleaning the wound, Jing Wanhong and Bao Mei Run Burn Ointment can be applied externally. For large-area burns, it is advisable to send them to the hospital as soon as possible. The treatment of scald is the most important. First, shave the hair around the injured area and cut off the long nails. Wash the healthy skin around the wound with soapy water and clean water, and then scrub and disinfect it with 0. 1% bromogeramine solution or 75% alcohol. Rinse the wound with isotonic saline to remove foreign bodies and dirt. Protect the blisters from being damaged. For large blisters, use an empty needle to extract the blood bubble fluid, or cut it at a low position to release the bubble fluid. If the blister is broken or seriously polluted, cut off the blister, gently roll it with gauze, cover it with a layer of liquid paraffin gauze or a thin layer of vaseline gauze, add multiple layers of degreasing gauze and cotton pad, and press and wrap it evenly. Burns can also be treated by bandaging therapy and exposure therapy. Burns are often complicated with infection, so antibiotics should be added and tetanus antitoxin can be injected. References:
