THE STATE OF MICROCIRCULATION AND TYPES OF HEMODYNAMIC DISORDERS IN CHILDREN WITH VEGETATIVE DYSTONY SYNDROME

Abstract

Objective: To study the state of microcirculation and to reveal the peculiarities of hemodynamics in children with dystonia syndrome in different age periods. Methods: 165 children aged 5 to 15 years with a syndrome of vegetative dystonia were examined, among them 79 children with the vagotonic type of the initial vegetative tonus (IVT); 35 – with the sympathetic-tonic type of IVT; 51 – with a mixed type of IVT. The state of the microcirculation was evaluated by the method of laser doppler flowmetry. Results: The most pronounced changes in the parameters of microcirculation were found in children with the vagotonic type of vegetative dystonia. Early violations of hemodynamics, manifested hyperemic type, were detected in 37.6%, and the most severe, stagnant-stasis type – in 49.1% of cases. It is proved that the number of children with congestive-stasis type of microcirculation increased from 7.3% of cases at the youngest age to 27.3% in the older age group. Conclusion: Infringements of microcirculation take place at children irrespective of type IVT. With increasing age of children with the syndrome of vegetative dystonia, the frequency of pathological types of hemodynamics increases.
