Abstract
The paper presents an analysis of the literature data concerning the autoregulation of tissue blood flow in free axial flaps. Autoregulation of microcirculation is an extremely important physiological phenomenon that ensures the stability of peripheral blood circulation and adequate metabolism in organs and tissues, regardless of fluctuations in systolic blood pressure in the range of 80-160 mm Hg. The types of sludge and their origin are described. Technologies of elimination of erythrocyte aggregates (sludge) by using dextrans of different molecular weights and pentoxifylline are discussed. Controlling the duration of primary ischemia, maintaining adequate perfusion pressure in the replants of the limbs and in free flaps, as well as reducing the peripheral vascular resistance in them, will make it possible to level the disturbances in the autoregulation of microcirculation in the reperfused tissues, ensuring the stability of capillary pressure.
