A third degree circumferential burn in the arm & forearm region, which of the following is most impoant for monitoring?

When deep second and third degree burn wounds encompass the circumference of an extremity, peripheral circulation to the limb can be compromised. Development of generalized edema beneath a non - yielding eschar impedes venous outflow and affects aerial inflow to the distal beds. This can be recognized by numbness and tingling in the limb and increased pain in digits. Aerial flow can be assessed by determination of Doppler signals in the digital aeries and the palmar and planter arches in affected extremities. Capillary refill can also be assessed.
