How does child boil water scald to have blister to handle

Children who are scalded by boiling water should be soaked in cold water immediately, which can promote vasoconstriction and relieve pain. After washing for 20 minutes, they should be disinfected with iodophor; if the scald blisters are small, they can be treated with scald ointment. For children with large blisters and severe burns, they need to go to the burn surgery department of the hospital for treatment.
