Acute Burn Excision / Skin Grafting | Early healing and rehabilitation

A fresh graft first adheres by fibrin formation, and blood supply begins within about 48 hours, so complete contact and immobilization matter. Stitches or staples hold edges; a bolster with cotton balls can provide roughly 30 mm Hg pressure. Vacuum-assisted closure may improve take in some settings, but it is technically difficult on a burned hand and larger series are still lacking. Full-thickness grafts are generally not used in acute burns because they need an ideal bed and dressing. Sheet grafts need early checks because hematoma or seroma beneath them can prevent adherence, while nonadherent dressings and bolsters reduce shear.

Graft take needs a healthy, well-blood-supplied bed and direct contact. Shear can move the graft; hematoma or seroma can lift it; infection or inadequate debridement can destroy fibrin; excess tension can cause ischemia; improper dressings or not following instructions can disrupt healing. Exposed tendon, bone or cartilage may not support a graft, while fat, peritenon, perichondrium or periosteum may support only thin split-thickness grafts. Diabetes, smoking, prior radiotherapy or chemotherapy and poor nutrition can also influence take. Streptococcus pyogenes, Pseudomonas aeruginosa and MRSA can destroy fibrin and prevent adherence. Graft failure can also result from insufficient wound bed or graft vascularity. Proper clinical and patient selection, meticulous execution, and close follow-up are essential to ensuring a successful graft.

The donor site is a fresh wound created to harvest skin, so it can hurt more than the grafted recipient area. Extra pain relief may be needed, especially for donor-site pain. Donor sites generally heal in 10–14 days and can be reharvested if needed; healing may take 1–2 weeks depending on age and size, and thinner grafts heal faster with less scarring. Dressing changes 3–5 days after grafting may include suture or staple removal, which patients often describe as very painful. Donor-site infection is among the most painful and prolonged complications. Donor sites are dressed to protect them and encourage moist healing.

After acute burn excision and grafting, the graft must adhere and gain blood supply before shear or pressure risks loss. Ambulation and out-of-bed activity should not begin until viability is established; leg or foot grafts may begin ambulation around postoperative day 5 if able. Exercises then progress from passive to active range of motion and strengthening as tolerated. Therapists need graft placement, movement restrictions and weight-bearing precautions; elastic compression and limited initial distances help protect the graft. Full-thickness grafts can help counter contracture over joints. Early mobilization is encouraged once the team confirms graft take, with precautions to avoid shear, pressure and excessive distance.

Grafts placed over joints, hands, feet, neck or axilla are especially vulnerable to movement, shear and contraction. Splinting can immobilize and protect the graft, reduce contracture risk and help maintain position during early healing. It may be planned before surgery, applied in the operating room, and revised during dressing changes. The exact splint, position and duration depend on burn site, graft stability and therapy input, not a single routine. Airplane splints may be used after axillary releases, while hand, elbow or neck splints may be tailored to the area. Therapists and occupational therapy can help customize support, and pressure garments may follow once grafts are stable. This support is individualized.

Large burns trigger hypermetabolism proportional to burn size up to 60% TBSA, plateauing by the end of the first week; most burns over 30% TBSA need intensive nutrition until healing. Calories may be estimated with the Curreri formula, 25 kcal per kg plus 40 kcal per percent TBSA, with a goal of 30–40 kcal per kg daily; protein is 2.5–3 g per kg daily, or 3–4 g in children. Feeding starts early, often by nasogastric tube, with stomach feeds held six hours before surgery; post-pyloric feeds can continue perioperatively. Weekly prealbumin and nutrition labs guide adjustments, and a registered dietitian should be involved early.

These signs usually point to more invasive infection and are not sensitive or specific enough alone, so laboratory tests are usually needed. The gold standard is histology showing organism invasion into the dermis, while cultures help identify organisms. Burn wound impetigo may appear as small multifocal superficial abscesses with little systemic response, though fever and raised white cells may occur, and it can destroy previously adherent grafts; cultures commonly show Staphylococcus aureus. Invasive signs include conversion of partial-thickness injury to full-thickness necrosis, hemorrhagic discoloration of subeschar tissue, green pigment in subcutaneous fat, or swelling and violaceous discoloration at the burn margin.

Post-burn itching often starts early, peaks around six months, and declines after the first year. It occurs in healed and grafted skin, but is more intense where hypertrophic scarring forms; grafted areas may itch less initially because the wound bed is insensate. Scratching can reopen wounds and may increase infection risk, while the itch-scratch cycle can reinforce symptoms. General guidance favours skin care, sleep hygiene, safe coping and individualised assessment rather than habitual scratching. Nurses may assess pruritus, sleep, distress and scratching, and provide skin-care, sleep-hygiene and safe coping education. Combining adjuncts with medicines may maximise symptomatic relief. Evidence-based reviews note promising pharmacological and non-pharmacological treatments, though research remains limited.

During rehabilitation, wound care is generally fairly simple, with minimal or no dressings, but healed skin remains fragile and can break down with little provocation. Caregivers should understand the need to moisturise with water-based creams to keep skin supple and reduce itch. Outpatient burn clinic visits allow wound evaluation and assessment of physical and psychological recovery. Ongoing rehabilitation through physiotherapy and occupational therapy, including range-of-motion exercises, ambulation, stretching and splinting, is adjusted as recovery progresses. Early rehabilitation can help prevent or reduce contractures. Caregivers should also watch for skin breakdown and report concerns promptly during follow-up. These are general principles; individual plans depend on burn size, depth, graft status and overall condition.
