A small amount of epidermal necrolysis in a surgical incision can be observed for healing, and if there is oozing from the incision, the wound can be cleaned and disinfected regularly, and the necrolysis can be removed if necessary. A small amount of epidermal necrolysis in the surgical incision is normal in most cases, mostly seen in larger incisions such as radical mastectomy, or larger trauma wounds. In general, necrotic epidermis can be observed for healing, and in most cases the necrotic epidermis can be removed on its own. For longer surgical incisions or traumatic wounds with necrotic epidermis, if combined with local oozing, in order to maintain the cleanliness of the wound, you can regularly clean and disinfect the wound with topical iodine povidone, and use topical epidermal growth factor gel to promote the healing of the wound. In the later stage, according to the epidermal necrosis situation, the necrotic epidermis can be removed if necessary.
