, Escharotomy is the surgical division of the nonviable eschar, which allows the cutaneous
envelope to become more compliantFull-thickness circumferential and near-
circumferential skin burns result in the formation of a tough, inelastic mass of burnt tissue
(eschar). The eschar, by virtue of this inelasticity, results in the burn-induced compartment
syndrome. This is caused by the accumulation of extracellular and extravascular fluid
c within confined anatomic spaces of the extremities or digits. The excessive fluid causes the
intracompartmental pressures to increase, resulting in collapse of the contained vascular
and lymphatic structures and, hence, loss of tissue viability. The capillary closure pressure
of 30 mm Hg, also measured as the compartment pressure, is accepted as that which
requires intervention to prevent tissue deat .
