If a large blister forms after a burn, do not pick the blister out by yourself. If you need to pick it out, please go to an outpatient clinic and pierce it with a sterilized syringe needle to avoid infection. Try to keep the herpes skin after the blister is pierced and avoid removing it, because the herpes skin of the blister has a protective effect on the wound. After the wound is rinsed with cold water and routinely disinfected with iodophor, you can apply scald ointment, such as compound polymyxin B, recombinant bovine alkaline growth factor topical gel, moist burn cream, etc., which have good therapeutic effect on the scald. Use clean gauze to bandage the wound, pay attention to the method when bandaging, do not bandage too tightly, so as not to affect blood circulation, such as burns on the extremities, bandage treatment after the final elevation of the affected limbs to reduce edema. If the wound is distributed in the face and perineum, it is not suitable to bandage the area using exposure therapy, pay attention to the protection of the scalded wound, try to avoid pressure, so as not to deepen the pressure on the wound.
