A burn wound that breaks the skin is usually a second-degree burn, and if it is not handled properly after the burn, it can cause the skin to break down. When the skin in the burn area breaks down, the base is exposed and is prone to more ooze and infection. After rinsing the injured area with cold water, it can reduce the surface temperature, reduce further damage, and clean; then after disinfecting with iodophor, which is non-irritating to the true layer of the skin, if the injured area is small, it can be treated externally with moist burn cream, comfrey burn cream, etc. If the area is large, it can be bandaged with iodophor-oil gauze to cover the trauma, and change the medication regularly. Note: Try to keep the broken epidermis when cleaning. To prevent infection, antibiotics such as amoxicillin and levofloxacin should be taken after the injury, and tetanus antitoxin should be injected to prevent tetanus. If the wound is painful, it can be treated with medications such as ibuprofen and diclofenac sodium. After the injury, you should go to the hospital and be treated under the guidance of a professional doctor.
