![]() ![]() However, good initial management, including dressings, can still prevent the burn from getting larger and deeper while the patient awaits review or transfer. ![]() If the zone of coagulation is large, it is likely that the patient will require specialist treatment and surgery. Reproduced with permission from Wound Healing Institute Australia. Jackson’s burn wound model. This model helps to explain the dynamic nature of burn injuries, and how an assessment of the burn at the time of injury can be different in terms of size and depth to an assessment of the same injury 48 hours later. Good first aid and wound management can significantly reduce the need for skin grafting, 1 simply by giving this middle zone the chance to recover, rather than deepen and become part of the zone of coagulation. The middle zone of the burn is called the zone of stasis, which is the target of good burns care, such as effective first aid and dressings. This is a reactive zone of inflammation in response to the injury, which can occur with non-burn injuries such as trauma, and will return to normal within hours of the injury. The outer zone of the burn is called the zone of hyperaemia. This area is dead and nothing any clinician can do will bring it back to life. The inner zone of a burn is the zone of coagulation. When considering burns dressings, it is useful to remember the theory of Jackson’s burn wound model (Figure 1). ![]()
