Skin grafting is used when a wound is too large or complex to bring the edges together with stitches, staples, or adhesive strips. This often happens after major trauma, burn injuries, or the surgical removal of large tumors, where primary closure is not possible, or with chronic ulcers where secondary healing would be slow or functionally impairing. The perioperative nurse should recognize wounds that have formed healthy, red granulation tissue, free of slough and necrosis, as suitable beds for grafting. Equally important is identifying bare bone, cartilage, or exposed tendon without vascularized covering, as these surfaces do not accept grafts unless prepared with granulation tissue or vascularized coverage first.

Contraindications include the presence of wound infection, uncontrolled systemic disease, or poor vascularity of the wound bed. If pus, malodor, or fluctuance is present, grafting should be delayed until infection is cleared. Similarly, ischemic limbs with inadequate perfusion will not support graft take. Nurses must be vigilant in recognizing these conditions during wound assessment and alert the surgical team. Additionally, systemic contraindications such as severe malnutrition, uncontrolled diabetes, or sepsis should be factored into readiness for surgery.

Knowledge of graft types is essential. Split-thickness skin grafts (STSG), which include the epidermis and part of the dermis, are most commonly used for large surface areas such as burns or traumatic wounds because they are reliable and donor sites can heal spontaneously within two to three weeks. Full-thickness grafts (FTSG), which include the entire dermis, provide better texture, pigmentation, and cosmetic outcomes, particularly for the face and hands. However, because the donor site cannot heal on its own, it must be stitched closed after the graft is taken. This limits how much skin can be harvested and makes FTSGs impractical for covering very large wounds. Composite grafts, which combine skin with underlying tissues such as cartilage or fat, are used in small specialized reconstructions like the nose, eyelid, or ear where structure is needed. Beyond autografts (tissue transfers on the same individual), nurses should also recognize the role of allografts (human cadaver skin) and xenografts (animal skin, usually porcine) as temporary biological dressings in extensive burn care; while these are not permanent, they reduce fluid loss and infection risk until an autograft can be performed. In addition, split-thickness grafts may be applied as sheets for cosmetic areas, meshed to expand their coverage for larger wounds, or fenestrated with a scalpel to allow drainage of exudate. Nurses should understand which graft type and preparation method are planned so they can anticipate instrument needs, assemble the correct dressings, and support postoperative monitoring of graft take and donor site healing.

A final factor is whether the patient can safely tolerate the anesthesia or pain control required for grafting, even if only local anesthesia is planned. While surgeons lead this decision, perioperative nurses must recognize that grafting is not appropriate if analgesia or anesthesia is not achievable, or if postoperative support (such as dressing maintenance) cannot be reliably provided. Their role in reinforcing correct indications and identifying contraindications is key to safe outcomes.

Informed consent must be obtained prior to skin grafting, and nurses often play a supporting role in reinforcing the information shared by the surgical team. Patients should be informed that grafting involves removing skin from one part of the body (the donor site) and placing it over the wound (the recipient site). The donor and recipient sites should both be identified for the patient, with explanations of how each will be managed postoperatively. Nurses should be ready to answer patient questions clearly and consistently.

Patients must be told about alternatives, including allowing the wound to heal by secondary intention, use of local flaps (if available), or deferring surgery until the wound improves. Outcomes should be explained realistically: grafts usually take well, but there is a risk of partial or complete graft loss. Possible complications include infection, bleeding, scarring, pigmentation changes, and functional or cosmetic differences at the donor site. Nurses should ensure the patient has had these explained in comprehensible language.

Pain is a frequent concern. Nurses should emphasize that the donor site is often more painful than the grafted area and requires attentive dressing care. The anticipated course of healing—typically two to three weeks for the donor site and inspection of the graft site after about one week—should be explained. Reinforcing the expected duration of immobilization and the importance of not disturbing dressings helps set patient expectations.

Finally, patients should be made aware that scars will form, and in visible donor areas, this may be permanent. The possibility of repeat grafting, should the first attempt fail, must also be discussed. The nurse should confirm that the patient verbalizes understanding before signing consent, ensuring it is both informed and voluntary.

Preparation of materials should follow a logical order on the Mayo stand. First, cutting instruments should be placed: a scalpel handle with No. 15 and No. 10 blades, scissors for fine trimming, and the dermatome or Humby knife with its gauge already set. These must be organized nearest the operator’s dominant hand. Adjacent should be forceps—one toothed for donor site stabilization, one smooth for atraumatic handling of the graft.

Next, placement tools should be arranged: skin hooks, fine non-toothed forceps, and a small skin stapler or sutures with appropriate needles. Dressings should be separated into sterile packs: paraffin gauze, cotton pads, roller bandages, and tie-over bolster materials (such as silk sutures and cotton balls). Each item should be pre-counted and laid out to anticipate graft placement without delay. Irrigation and cleansing equipment should be grouped: sterile saline in syringes or basins, gauze swabs, and suction tubing ready for intraoperative debridement. Hemostasis materials such as bipolar cautery or artery forceps with ligatures should be available for bleeding points at donor or recipient sites. Nurses should confirm all materials are functioning and within sterility standards before incision.

Finally, anesthesia equipment should be checked and placed separately but within immediate reach of the anesthesia team. This includes syringes with local anesthetic, resuscitation equipment, and oxygen supply. The perioperative nurse must confirm all safety checks are complete and instruments are orderly, ensuring a smooth transition from preparation to harvest to placement.

Donor site selection must balance surface area, skin type, and visibility. The thigh is the most common donor site because of its wide, flat surface, ease of access, and concealment under clothing. Other possible sites include the buttocks, upper arm, and back. The perioperative nurse should confirm the surgeon’s planned donor site, then prepare the area by shaving and cleaning it. Familiarity with common donor sites (such as the thigh or buttocks) allows the nurse to anticipate equipment and positioning needs, but final selection is always directed by the surgeon.

In the operating room, once the wound bed is exposed and cleaned, the surgeon measures the recipient site directly using a sterile ruler or sterile drape markings. Because harvested grafts contract after removal, the donor site must be about one and a half times larger than the recipient bed. Nurses must assist in measuring and confirming that the donor site provides adequate tissue without exceeding safe limits of donor surface area, especially in small patients.

Skin type matters for cosmetic outcomes. For facial wounds, donor skin should be thin and close in color, often taken from the upper inner arm. For extremities, the thigh provides strong matches. Nurses should be aware of these considerations so they can prepare the appropriate donor area and anticipate postoperative cosmetic concerns. Accessibility is another critical factor. The donor site should allow good exposure, stabilization, and ease of dressing. Areas over joints or high-mobility zones may complicate dressing application and healing. The perioperative nurse must ensure the patient is positioned to optimize both harvest and subsequent immobilization, avoiding tension on donor site dressings.

In a typical skin grafting procedure, the wound bed is first cleaned and debrided until healthy tissue is visible. The surgeon then harvests a graft from the donor site using a dermatome or knife, and the graft is immediately placed in sterile saline to prevent drying. If a large wound requires more coverage or if drainage needs to be facilitated, the graft may be meshed using a skin mesher or fenestrated manually with a scalpel. Once prepared, the graft is carefully spread over the recipient site with the dermal side down, trimmed to fit, and secured with sutures, staples, or a tie-over bolster dressing. A non-adherent layer and compression dressing are applied to keep the graft immobile and in close contact with the wound bed. During the procedure, the scrub nurse maintains the sterile field and assists with instruments and graft handling, while the circulating nurse supports by bringing additional supplies, recording details, and coordinating care outside the sterile field

During harvest, after two to three strokes of the Humby knife, the nurse should check the thickness and bleeding of the graft. If bleeding is excessive, the gauge may be too deep and needs adjustment. Nurses should anticipate stopping the harvest if bleeding soaks through swabs quickly, notifying the surgeon to reset depth or choose a new site. If the graft appears too thin, it may tear easily during placement. Nurses must handle grafts delicately with smooth forceps and keep them moist in saline-soaked gauze until placement. If tearing occurs, small fragments can still be used to cover smaller areas or meshed to expand coverage.

Anticipating spare saline-soaked swabs and fine instruments reduces the risk of losing usable graft material. When a graft rolls or curls on itself, nurses should gently unfurl it with saline-moistened gauze and avoid stretching with forceps tips. Rolling indicates uneven thickness, often correctable with careful trimming. Nurses must be attentive to maintain orientation, ensuring the dermal side faces the wound bed. Misorientation leads to graft failure. During placement, if fixation is unstable, tie-over bolster dressings or additional sutures may be required. Nurses should prepare extra suture material and cotton balls in advance. If graft adherence is questioned due to bleeding or hematoma, gentle pressure dressings and additional hemostasis are needed. Nurses play a crucial role in identifying these problems intraoperatively.

Recipient site dressings should begin with a layer of paraffin gauze, which prevents the graft from adhering to the dressing itself and allows gentle inspection later. Over this, cotton pads or foam are shaped carefully to match the contours of the wound so that even surfaces such as the thigh, or more irregular ones like the scalp or hand, receive uniform pressure. In larger or mobile areas, tie-over bolster dressings are often used: long sutures are left in place around the wound edges, and once the padding is positioned, the suture ends are tied securely over it. This stitches the dressing to the skin in effect, holding the graft in close apposition to the bed while preventing shear forces or fluid collection beneath it. Where bolsters are not required, firm external bandaging can serve the same purpose, provided care is taken to achieve even pressure without compromising circulation. Postoperatively, the recipient dressing is usually left untouched for at least five to seven days, as disturbance too early can dislodge the graft. Nurses play a key role in educating staff and patients to protect the area, monitor for signs of strike-through bleeding, and maintain immobilization until the first inspection.

Donor site dressings require a different approach. Because a split-thickness harvest leaves a raw surface similar to a large superficial abrasion, the aim is to protect it while re-epithelialization occurs from remaining dermal structures. Once hemostasis is secured, a sheet of paraffin gauze is laid directly over the donor site to prevent adherence and painful removal. Absorbent cotton pads or foam dressings are then placed to manage the expected oozing of blood and serous fluid, and these are held in place with a snug bandage that provides enough pressure to prevent bleeding yet avoids constriction. Unlike recipient sites, donor sites are not stitched; their healing depends on the intact dermal remnants. Nurses should anticipate that donor areas are often more painful than grafted wounds, and careful bandaging reduces exposure to air, minimizes discomfort, and promotes faster epithelial regrowth. Outer dressings may need reinforcement if soaked, but the non-adherent layer is best left undisturbed for several days to support uninterrupted healing.

Close observation in the immediate postoperative period is essential, as seepage of blood or serous fluid through the outer dressings may signal inadequate hemostasis or early strike-through. While outer layers can be reinforced if saturation occurs, the deeper non-adherent layer should remain undisturbed, since early interference can easily shear the graft from its bed. Recipient site dressings are usually left in place for five to seven days, with the first inspection typically performed at the end of that interval, when graft adherence can be assessed reliably. Donor sites, by contrast, may require attention sooner, as their raw surface often produces more fluid; here, only the outer absorbent pads should be changed, leaving the paraffin gauze in place to protect fragile new epithelium.

If the graft has taken well, lighter protective dressings are applied until the surface matures. Complete healing and remodeling of the graft typically occur over several weeks, with the skin gradually strengthening and softening, and the donor site regaining an epithelial covering in two to three weeks. By the end of this process, both sites are stable, though color and texture changes may persist for several months, and scar maturation may continue for up to a year.

Nurses play a key role in teaching patients and ward staff to avoid tampering with either site, to report strike-through bleeding promptly, and to recognize that pain is often greatest at the donor area. In difficult anatomical locations such as the scalp, face, or digits, contoured bolster dressings—assembled from cotton balls or foam tied down with pre-placed sutures—may be required to maintain steady pressure across irregular surfaces. Whether simple or specialized, maintaining dressing stability for up to two weeks is critical to optimizing graft survival, minimizing infection, and ensuring patient comfort.

In environments with limited equipment, nurses may substitute instruments with sterile, sharp scalpel blades if dermatomes or Humby knives are unavailable. Gauze sutures can be fashioned from available silk or nylon sutures to secure bolster dressings if pre-formed kits are not present. For hemostasis, sterile gauze pressure and artery forceps may replace cautery units. Knowledge of these substitutions allows grafting to proceed safely despite equipment shortages.

When personnel are limited, one nurse may need to both assist the surgeon with instrument handling and simultaneously prepare dressings. To manage this, nurses should pre-pack donor and recipient dressing sets before the incision. During harvest, a single assistant can stabilize the limb with sterile towels or improvised supports while also handing instruments. Efficiency and foresight become essential skills in ensuring grafting can proceed even with minimal staff.
