1, cold therapy: After low-temperature burns, patients should be given cold therapy in time, such as washing the wound with cold water, cold compress or cold compress with an ice pack towel, which will help to cool the wound quickly and reduce the residual heat to continue to damage the tissue. However, the cold therapy time should not be too long, generally 20-30 minutes each time to avoid secondary effects.
2. Medical treatment: If there is local blister or epidermal ulceration, the patient needs to go to the burn department for further treatment. If the unbroken blister needs to avoid friction and oppression, it can be absorbed by itself. The liquid in the blister should be pumped out with a sterile syringe under aseptic operation, and the wound should be bandaged with a sterile oily dressing. Patients with epidermal ulceration can be disinfected with hydrogen peroxide or iodophor, and the surrounding skin should be kept clean and dry.
Old people and children are prone to cryogenic burns, so when using hot water bottles and electric blankets to keep warm in winter, pay attention to heat preservation, and don't use them for a long time.
