In a burn patient, which sign would most strongly indicate the need for an escharotomy?

• A. Absent distal pulses
• B. Palpable distal pulses
• C. Normal cap refill
• D. Warm extremities

Answer: (A)

In burn patients with circumferential full-thickness eschar, the pressure from the eschar can compress underlying vessels and raise limb compartment pressures, risking ischemia. The clearest sign that urgent relief is needed is the loss of distal arterial inflow, so absent distal pulses strongly indicates a vascular compromise that warrants escharotomy. When distal pulses are palpable, cap refill is typically normal, and the extremities feel warm, these findings suggest perfusion is still preserved, so an escharotomy is not indicated based on those signs. In short, the absence of distal pulses signals the need to relieve the constricting eschar to restore blood flow.
