In the management of burns, the Jackson's zones of injury model describes three concentric zones. The zone which has the potential for recovery with optimal resuscitation is:

A Zone of coagulation
B Zone of hyperaemia
C Zone of stasis ✓
D Zone of necrosis

Correct answer: C. Zone of stasis

Explanation

Jackson's zones of burn injury: (1) Zone of coagulation — central, irreversibly necrotic tissue (immediate cell death due to protein denaturation); (2) Zone of stasis — surrounding the central area, this zone has impaired microvascular perfusion and is at risk of conversion to full-thickness necrosis but CAN be salvaged by optimal resuscitation (adequate fluid replacement, avoiding vasopressors, topical antimicrobials, pressure relief); (3) Zone of hyperaemia — outermost zone, tissue that will recover without intervention due to vasodilatation and inflammatory response. Zone of stasis is the clinical target of burn resuscitation.
