Patients with extensive deep burns usually experience infections and organ dysfunction. Proactive and effective wound repair is key to treatment. If large wounds remain open, systemic infection and multiple organ dysfunction syndrome can occur, threatening the lives of patients. Current wound repair methods include skin grafts, flap repair, negative-pressure wound therapy, and cellular and/or tissue-based products. For deep, complex burn wounds, a single form of treatment is usually ineffective. This article reports a rare case of burn wound repair. The patient was burned by a charcoal flame on multiple parts of his body after carbon monoxide poisoning. Pneumothorax and acute renal failure occurred after the injury, accompanied by multiple osteonecroses of the trunk and lower limbs. A multidisciplinary team formulated an individualized treatment plan; the diverse treatments included closed chest drainage, continuous renal replacement therapy, infection control, analgesia, wound debridement, negative-pressure wound therapy, cellular and/or tissue-based products, autologous dermal scaffold graft, skin grafts, flap transposition, platelet-rich plasma, and rehabilitation, which ultimately saved the patient's life and led to healing of all the wounds.
