Delayed healing of skin donor sites may be costly and life threatening, especially in patients with large body-surface area burns. A donor site dressing should maximize the ability of the wound to heal without increasing the risk of local infection, systemic infection, or both. Specifically, the possibility of a secondary infection may either slow the healing process or ultimately convert the donor site to a full-thickness wound. A number of materials, ranging from gauze to biological agents, have been investigated for use as donor site dressings. The use of hydrocolloids for donor sites has been studied extensively, and, compared with conventional dressings, improved healing rates are reported. Our recent study using a hydrocolloid dressing confirmed earlier research showing fewer infections and more rapid donor site healing.
皮肤供区延迟愈合可能代价高昂且危及生命，尤其是对于大面积烧伤患者。供区敷料应在不增加局部感染、全身感染或两者风险的情况下，最大限度地提高伤口愈合能力。具体而言，二次感染的可能性可能会减缓愈合过程，或最终使供区转变为全层伤口。从纱布到生物制剂等多种材料已被研究用作供区敷料。水胶体用于供区的应用已得到广泛研究，与传统敷料相比，据报道愈合率有所提高。我们最近使用水胶体敷料的研究证实了早期研究结果，即感染更少且供区愈合更快。
