The aim is to study the complex stimulation effect including skin autotransplantation and electrical stimulation of the sciatic nerve on microcircular, electrophysiological and morphological changes after deferred neurorrhaphy in rats. Material and methods. The experiment was performed in 50 albino rats divided into control, comparative and experimental groups. In the experimental group, on the background of deferred neurorrhaphy, skin autotransplantation and electrical stimulation of the sciatic nerve had been carried out. In the comparative group only deferred neurorrhaphy was performed. Research methods included laser doppler flowmetry, electroneuromyography and morphological analysis of the operated nerve. Results. Complex stimulation including skin autotransplantation and direct action of electrical pulses on the sciatic nerve after its deferred neurorrhaphy causes restoration of bloodstream in the operated limb, promotes intensification of restoration of nerve fibers. Conclusion. Intensification of sciatic nerve regeneration after deferred neurorrhaphy in rats under the influence of complex stimulation including full-thickness skin graft autotransplantation and direct action of electrical pulses substantiates experimentally appropriateness of clinical testing of the given method for treatment of patients with peripheral nerve injuries.
