How would you determine timing for excision and grafting in burn wounds?

• A. Delaying all grafts until complete spontaneous healing is achieved.
• B. Early excision and grafting are indicated for full-thickness or deep partial-thickness burns unlikely to heal promptly, to reduce infection and hospital stay.
• C. Grafting is never indicated in burns unless infection occurs.
• D. Excision should be delayed until necrotic tissue is clinically evident.

Answer: (B)

In burn care, the timing of excision and grafting hinges on how deep the burn is and whether it is likely to heal on its own. For full-thickness or deep partial-thickness burns that are unlikely to close promptly, performing early excision to remove non-viable tissue and then grafting provides the quickest path to durable wound closure. This approach reduces bacterial burden, lowers the risk of infection, limits fluid loss, and dampens the systemic inflammatory response, all of which shorten hospital stays and improve functional outcomes. Timely closure also helps prevent extensive scarring and contractures that can occur with delayed healing.

Typically, when the patient is hemodynamically stabilized, and the burn depth makes spontaneous healing unlikely, surgeons target early intervention—often within the first 24 to 72 hours—subject to the patient’s condition and resource availability. Waiting for spontaneous healing in deep burns is not advisable because prolonged open wounds raise infection risk and delay recovery. Excision is not delayed until necrotic tissue is evident, since necrosis can serve as a nidus for infection and hinder healing. Grafting is not reserved only for infections; it is a proactive step to restore the skin barrier when closure is unlikely without intervention.
