[Changes in components of the vascular tone and microcirculation indices in frostbites of lower extremities].
The state of the microcirculation bed was assessed by the method of laser Doppler flowmetry in 40 patients with frostbites of lower extremities of the II-IV stages. In the proximal zone segments there was less inflow of blood to the arterial bed, increased neurogenic and myogenic components of vascular tone, decreased nutritive and, in a less degree, shunt blood flow. In aggravation of the injury severity the changes in question become more pronounced.
