After a hand burn, it is first necessary to promptly cool the area. This can be done by rinsing with running clear water, or applying cold compresses such as ice packs or ice cubes to the burned area to quickly reduce the temperature and relieve pain.

Then, observe the extent of the burn on the hand. If it is only some redness and swelling, disinfect with iodine and then apply some medicine for treatment. If blisters appear after the burn, which usually indicates a second-degree or more severe burn, sterilized needles can be used to puncture the blisters. After disinfecting with iodine, apply burn ointment or alternate with erythromycin ointment to help promote wound healing. For extensive burns on the hand, self-treatment can easily lead to infection, and in such cases, it is necessary to go to the hospital for dressing, antibacterial, and anti-inflammatory treatment to avoid hand infection and tissue necrosis.
