Аннотация
Healthy people (n = 16), patients with autonomic dystonia syndrome (n = 38), and patients with traumatic rupture of the median nerve before and after nerve suture (n = 28) were examined by laser Doppler flowmetry (LDF) with a computer wavelet analysis of blood flow oscillations. Functional states (FSs) of the microcirculatory bed wеre assessed using energetic and information indices of microvascular blood flow oscillations. The variation coefficient and the information regime (multistable or resonance) were used as key characteristics. Oscillatory processes are an integral part of adaptation and the FS formation in the microvascular bed. FSs were classified as adaptive, hyperadaptive, hypoadaptive, and failure of adaptation. Because supporting the optimal function of nutritive microvessels is a leading component of the adaptation process, FSs of nutritive and nonnutritive microvessels may differ. A selective contribution of the autonomic sympathetic regulatory channel was related to maintaining considerable hyperadaptation in the microvascular bed with overstrain or marked overstrain of regulatory systems, as in emotional stress. Hypoadaptive FSs formed when skin blood flow increased, an excess decrease in flow resistance was unnecessary, and especially when regulatory factors were in deficiency, e.g., in neurodystrophic syndrome.
