A graft similar to a mesh graft in which a section of skin is removed except for small, regularly spaced areas that remain. The removed portion is used at the new site. The small remaining areas will grow to cover the entire area at the donor site.
The use of small sections of skin harvested from a donor site and transplanted to an injured area of skin to repair a defect, such as a large full-thickness burn. Commonly used grafts include split-thickness, full-thickness, and xenografts. Biosynthetic grafts (collagen and synthetics) also are used to minimize fluid and protein loss from burn injuries, prevent infection, and reduce pain. The skin surface at the receiving site should be clean and raw.
Before surgery, assessments are made of the patient's general health. Confirmation is needed that appropriate laboratory parameters, including hemoglobin and coagulation studies, are acceptable as they may affect the surgical result. The donor and recipient sites are prepared according to protocol. The postsurgical appearance of the wound and dressing and, if applicable, the need to immobilize the part after surgery are explained. Both patient and family receive support and encouragement. The graft is observed at regular intervals postoperatively for swelling or for development of hematoma and signs of purulent drainage. Aseptic technique is followed in applying dressings and compresses to prevent infection. Prophylactic antibiotics are administered as prescribed, and the graft site is immobilized to allow healing. Analgesics are administered as necessary to relieve pain. Before discharge, the patient learns about wound care and the need to keep the graft site clean, well lubricated, and away from sunlight according to the health care provider's instructions. Elastic support garments, reconstructive surgery, physical and occupational therapy, and psychological counseling may be required.

A graft of a part of the epidermis and part of the dermis. Synonym: split-skin graft
