circumferential burn
Burn injury completely encircling an extremity or body part, potentially compromising circulation.
Full Definition
A burn injury that completely surrounds the circumference of an extremity, digit, neck, or torso, creating a ring of burned tissue. These injuries are particularly dangerous because as the burn wound contracts and swells, it can act like a tourniquet, compromising blood flow and causing compartment syndrome. Circumferential burns of the chest or neck can restrict breathing by limiting chest wall expansion or causing airway compression. Immediate assessment of circulation, sensation, and movement is critical. Treatment often requires escharotomy or fasciotomy to relieve constriction. Deep circumferential burns have a high risk of complications and typically require aggressive surgical intervention and close monitoring.
Usage
