Burn and plastic surgery patients often face an important problem after discharge from the hospital, which is the care of the skin donor area. If the donor area is well cared for, the area will not only be free of scarring, but also shorten the treatment time, while on the other hand, the results will be unsatisfactory. The following is my personal understanding of how to care for the donor area. According to the thickness of the skin, the donor area can be divided into thick skin donor area, medium-thick skin donor area, and full-thick skin donor area; according to the site can be defined as the corresponding parts, such as scalp skin donor area; back skin donor area; abdomen skin donor area, outer thigh skin donor area, etc. Generally speaking, the skin donor area is equivalent to a superficial second-degree burn, and pathologically speaking, it should heal in 5-7 days after surgery. Therefore, the care is to temporarily cover and protect the trauma, keep the local clean and dry, and generally do not affect the local function after the trauma heals. Of course, since the early newly grown skin has poor abrasion resistance, it is best to give appropriate protection (topical dressing protection). As the skin heals with the keratinization of the new epidermis, a certain amount of oily liquid can be given to moisturize it after cleaning. For areas where the skin is too deep due to removal, a certain amount of time needs to be given for dressing changes. For trauma healing days over 21 days without healing, most of them have to grow a scar and need to be treated with anti-scar medication and pressure to prevent the proliferation of the scar.
