Scientific job: CLAIMED. This article owns the public clinical movement from burn event → mechanism + extent/depth + airway/systemic severity → emergency stabilisation → fluid/temperature/respiratory support → wound surgery and grafting where needed → infection/nutrition state → scar management → rehabilitation → long-term function. Wound Care retains general tissue-healing ownership; Surgery retains generic operative care; Burn Medicine owns the burn-specific systemic and reconstructive trajectory.

Wait, what? A burn can be much larger than the skin you can see.

Burn injury can affect skin, airway, circulation, temperature control, fluid balance, metabolism, infection risk, movement and long-term function. Electrical burns may cause deeper injury than the surface suggests. Inhalation injury can make the airway and lungs the most urgent problem. Chemical burns can continue damaging tissue until the agent is removed appropriately.

That is why major burn care is not simply wound dressing on a larger scale. It is a coordinated acute-care, surgical and rehabilitation system.

The major-burn tube

Burn event → mechanism → airway/breathing/circulation gate → burn extent + depth + critical anatomical areas → specialised-burn referral decision → resuscitation + temperature + analgesia → wound assessment → excision/grafting where indicated → infection/nutrition/metabolic support → rehabilitation from day one → scar reconstruction → return to function.

1. Mechanism changes the injury state

Thermal burns, scalds, electrical injury, chemical exposure and inhalational injury are not interchangeable. The mechanism can change depth, hidden tissue injury, airway risk, cardiac risk and the urgency of decontamination or specialist assessment.

For eduKateAI, every burn event should preserve mechanism, time, source, exposure duration where known, enclosed-space exposure, electrical voltage context where relevant and whether chemicals or smoke were involved.

2. Burn extent and burn depth are different objects

The percentage of body surface area burned estimates how much of the body is affected, while burn depth describes how deeply tissue has been injured. A smaller deep burn over the hand or face may have major functional consequences even when the total body surface area is limited.

Singapore General Hospital’s Burns Centre uses specialised admission criteria that include burn size, special areas such as face/hands/perineum, inhalational injury, electrical or chemical causes and deep burns requiring surgery.

3. Airway and inhalation injury can outrank the visible burn

Smoke and heat exposure can injure the airway and lungs. Swelling may progress after the initial event. A patient with modest-looking skin injury can therefore still have significant respiratory risk.

Emergency/Critical Care and Respiratory Medicine own general airway/ventilation physiology; Burn Medicine owns how inhalational exposure modifies burn severity, transfer and ongoing treatment.

4. Major burns create a fluid and temperature problem

Large burns disrupt the skin barrier and can produce major fluid shifts and heat loss. Selected patients require formal fluid resuscitation and close monitoring of circulation, urine output and organ function.

For eduKateAI: burn size ≠ fluid prescription by itself. Resuscitation depends on clinical context and repeated physiological receipts rather than a formula detached from the patient.

5. Early surgery can change the wound trajectory

Deep burns may require excision of non-viable tissue and skin grafting. SGH’s Burns Centre has an operating theatre dedicated to primary wound excision and grafting for major burn patients.

Surgery owns the operative event. Burn Medicine owns when excision/grafting fits inside the burn trajectory and how the graft is protected through recovery.

6. Infection risk changes when the skin barrier fails

Burn wounds can become colonised and infected, and severe infection can threaten grafts, limbs or life. But microorganisms detected on a wound do not automatically equal invasive infection.

Infectious Disease and Microbiology own organism and antimicrobial questions. Burn Medicine owns how infection changes the burn wound, graft and systemic recovery state.

7. Major burns are metabolically expensive

Large burns can produce sustained metabolic stress and high nutritional needs. SGH’s burn team includes dedicated nutrition support because tissue repair and recovery require more than wound closure.

Clinical Nutrition owns nutritional assessment and prescription; Burn Medicine owns how burn severity, surgery and wound-healing demands change that requirement.

8. Rehabilitation starts before the wounds are finished healing

Burn scars can shorten, stiffen and restrict joints. Pain, weakness and prolonged immobility can also reduce function. SGH describes burn physiotherapy beginning from the first day of admission and continuing through outpatient rehabilitation, with stretching, mobilisation, gait work and return-to-work reintegration.

This is a powerful movement rule: rehabilitation is not something that waits until the medical problem is over. It runs in parallel with wound healing.

9. Scar management is a long-duration state

Even after wounds close, hypertrophic scarring, contracture, itch, altered sensation, appearance and restricted movement can persist. Some patients require pressure therapy, splinting, therapy or reconstructive surgery.

The human receipt is therefore not “skin closed”. It is skin healed + movement preserved/restored + pain/itch controlled + participation and appearance concerns addressed.

10. Major burns are a health-system stress test

WHO’s burn-care guidance emphasises that mass burn incidents can overwhelm local capacity and require specialist teams, referral systems and surge planning. Burn Medicine therefore links individual care with disaster and health-system preparedness.

For eduKateAI, the receiver may be either one patient or a burn system under surge. The same injury can have very different outcomes depending on whether specialist capacity is reachable.

Characteristic failure modes

• Skin-only error: airway, circulation and systemic effects disappear behind the visible wound.
• Surface-size-only error: depth and special anatomical areas ignored.
• Small surface = minor error: electrical or inhalational injury underestimated.
• Wound-care-only error: resuscitation, nutrition and intensive care omitted.
• Closure = recovery error: scars, contractures and function disappear from outcomes.
• Rehabilitation-late error: mobility work delayed until after wound closure.
• Single-team error: burn surgery, nursing, respiratory, nutrition and rehabilitation fail to converge.

The eduKateAI routing contract

• Canonical public owner: Burn Medicine & Major Burn Care Web.
• Input state: thermal, scald, chemical, electrical or inhalational burn injury.
• Primary job: preserve mechanism, extent/depth, airway/systemic severity, surgical/wound needs and long-term rehabilitation as one trajectory.
• Do not collapse: visible burn ≠ total injury; extent ≠ depth; wound closure ≠ recovery; burn care ≠ dressing care alone.
• Handoffs: Emergency/Critical Care, Plastic/Reconstructive Surgery, Respiratory, Wound Care, Infectious Disease, Clinical Nutrition, Anaesthesia, Rehabilitation and Mental Health.
• Return receipt: airway/physiology stable, wound viable/closed, graft accepted or not, infection controlled, range/function preserved, scar management active, return-to-home/work trajectory established.
