In a patient with extensive burns to the left leg, which finding indicates the need for immediate intervention?

• A. Increased pulse.
• B. Strong pedal pulses.
• C. Normal capillary refill.
• D. Decreased pulse and capillary refill.

Answer: (D)

Distal perfusion is the critical issue in a limb with extensive burns. A diminished distal pulse paired with delayed capillary refill shows arterial inflow to the leg is compromised and tissue is not being adequately perfused. This is an urgent warning sign because without prompt relief of the pressure or restoration of flow, the tissue can quickly become necrotic or develop compartment syndrome. Immediate steps focus on relieving constriction and restoring circulation, such as removing tight dressings or eschar and involving surgical teams for possible escharotomy or fasciotomy. By contrast, a strong distal pulse with normal capillary refill indicates preserved perfusion, and a higher heart rate can be related to pain or stress rather than limb ischemia, so those signs do not point to an immediate vascular problem in the limb.
