Condition analysis: Low-temperature burn refers to the scald caused by a low-heat object above body temperature, although the basic temperature is not high. Burns are divided into first degree burns, second degree burns and third degree burns, and the treatment methods are also different. The corresponding treatment for low-temperature burn is: 1, first degree scald. The first degree scald is only on the cortical surface, with slight redness, no blisters and obvious pain. You should take off your clothes and socks immediately, soak the wound in cold water for half an hour, and then apply rape flowers to the wound. 2. Second degree burns. Second-degree scald is dermal injury, local swelling and pain, and blisters of different sizes. The big blister can be drained by disinfection needle, and then wrapped with scald cream, with appropriate tightness. 3. Third degree burns. Third-degree scald is the damage of subcutaneous fat and muscle, which is gray or reddish brown. At this time, the wound should be wrapped with clean cloth and sent to hospital for treatment. You should keep calm after a low-temperature burn. Rinse with cold water for more than 20-30 minutes until the local pain basically disappears. You can take off your clothes after washing, and don't tear blisters when you take them off, so as not to aggravate skin infection. The temperature of cold water is about 20℃, so ice water can't be used, because ice water is easy to cause secondary trauma.
