Arm skin graft: healing, care and warning signs

A surgeon places healthy skin taken from another body area over a prepared wound. Both the graft and the donor site require wound care, and the final colour, texture and sensation may differ from surrounding skin.

Skin grafting can cover a wound left by injury, a burn, infection or removal of abnormal tissue. The wound bed must be healthy enough to nourish the transferred skin. At first, the graft receives nutrients from the surface beneath it; new small blood vessels then connect with it.

A dressing, splint or firm bolster may limit movement and prevent fluid collecting under the graft. The donor site often resembles a graze if a thin layer of skin was taken. A thicker graft leaves a wound that is usually closed with stitches.

Keep dressings dry and in place for the period specified by the surgical team. Elevate the arm if advised, avoid stretching or rubbing the graft, and do not lift with that arm until movement restrictions are lifted. Take prescribed medicines as directed rather than adding creams beneath the dressing.

Attend dressing checks because the team may need to inspect graft attachment, remove a bolster or adjust a splint. Once the skin is closed, ask when moisturiser, scar massage, sun protection and rehabilitation exercises can begin. Gradual movement helps limit stiffness without pulling on fragile tissue.

Contact the surgical team promptly for increasing pain, spreading redness, warmth, swelling, foul odour, pus, fever, bleeding that soaks through the dressing, or a dressing that slips and exposes the graft. Darkening, unusual paleness, blistering or separation of the graft also warrants assessment.

Seek urgent care if the hand becomes cold, blue, very swollen or numb, or if a tight bandage causes severe pain. Sudden breathlessness or chest pain requires emergency help. Do not remove a fixed dressing to inspect the area unless your care team has told you to do so.

Ask what type of graft is planned, where the donor skin will come from, how arm movement will be restricted, and who to contact if the dressing changes. It is also useful to clarify when work, driving, bathing and exercise can resume, and whether hand therapy or scar treatment may be needed.
