Severe thermal burns are serious injuries caused by exposure to heat, flame, hot liquids, or steam. They can damage multiple layers of skin and underlying tissues, often leading to extensive tissue loss, scarring, infection, and impaired function. While immediate emergency care is critical, Hyperbaric Oxygen Therapy (HBOT) can serve as an adjunctive treatment to support tissue healing, reduce complications, and improve outcomes in severe burn cases. HBOT enhances oxygen delivery to injured tissue, helping to accelerate healing, reduce swelling, and minimise the risk of infection and tissue necrosis.
Understanding Severe Thermal Burns
Severe burns often affect deeper layers of the skin (second- and third-degree burns) and may extend to muscles, tendons, or even bone. Common causes include:
- Fires and explosions
- Scalding liquids or steam
- Electrical burns causing thermal tissue damage
- Contact with hot surfaces or molten substances
Severe burns trigger an intense inflammatory response, often leading to tissue oedema, reduced blood flow, and hypoxia (low oxygen levels) in the injured area. This can slow healing, increase the risk of infection, and contribute to scarring or contractures.
How HBOT Supports Burn Recovery
Hyperbaric Oxygen Therapy is used as an adjunctive therapy to improve oxygenation, support tissue repair, and prevent secondary complications. Therapeutic Benefits of HBOT 1. Increases Oxygen Delivery to Injured Tissue HBOT saturates the blood with oxygen, allowing it to reach hypoxic or poorly perfused areas, which is critical for burn healing. 2. Reduces Tissue Swelling Increased atmospheric pressure helps decrease oedema, improving circulation and oxygen delivery to damaged tissue. 3. Enhances Immune Response Oxygen-rich conditions improve white blood cell function, helping to fight infection in burn wounds. 4. Supports Tissue Regeneration HBOT stimulates collagen production, angiogenesis (new blood vessel formation), and repair of damaged skin and underlying tissues.
HBOT in Multidisciplinary Burn Care
HBOT is not a replacement for standard burn care but is used alongside:
- Immediate wound management and debridement
- Skin grafting or flap procedures
- Fluid resuscitation and pain management
- Infection control and antibiotic therapy
- Physical therapy and rehabilitation
Treatment typically involves multiple HBOT sessions, tailored to the depth and severity of the burn, as part of a coordinated care pathway.
HBOT Availability in the UK
In the UK, patients with severe thermal burns may be referred to specialist burn units with access to accredited hyperbaric centres. Treatment is delivered under specialist supervision, following established clinical protocols and safety standards. HBOT may be used pre- or post-surgically to optimise tissue survival and support wound healing.
Clinical Outcomes and Recovery
When used appropriately, HBOT may contribute to:
- Improved tissue survival and healing
- Reduced risk of infection and tissue necrosis
- Faster recovery and reduced hospital stay
- Enhanced graft or flap integration
- Better functional and cosmetic outcomes
Early intervention is key to maximising the benefits of HBOT in severe burn injuries.
FAQs About Severe Burns and HBOT
HBOT is generally reserved for deep, severe burns or wounds at risk of poor healing. Superficial burns rarely require HBOT.
No. HBOT supports healing but does not replace surgical interventions such as debridement or skin grafting.
Treatment usually involves multiple sessions over several days or weeks, depending on wound severity and response.
Yes. When delivered under specialist supervision, HBOT is safe and can support graft and tissue survival.
By promoting faster tissue repair and improving oxygenation, HBOT may help reduce the severity of scarring and support better functional outcomes.
Conclusion
Severe thermal burns are complex injuries that require prompt and comprehensive medical care. Hyperbaric Oxygen Therapy provides valuable adjunctive support by improving oxygen delivery, reducing swelling, fighting infection, and promoting tissue repair. When integrated into a multidisciplinary burn care pathway, HBOT can help enhance healing, protect grafts or flaps, and improve both functional and cosmetic outcomes for patients with serious burn injuries.
