Patients and methods. We analysed the results of examining healthy children aged 3 to 17 years and also young people under 25 years of age with the use of nail-fold capillaroscopy (n = 65) and laser Doppler flowmetry(n = 50). Results. According to capillaroscopy, no significant differences in microcirculation parameters in children of varied age have been obtained, but as has been found, diameters of all parts of capillaries and the width of perivascular spaces increased to some extent with children's age. Also, the density of first-line capillaries increased with age in the examined patients. The average microcirculation values obtained by LDF did not show any statistically significant difference between children from the age group 7 to 13 years and children aged 13 to 18 years. Microcirculation parameters are not dependent on a patient's age. The average values of PI may be used as reference parameters for diagnosing microcirculation impairments in children with varied pathologies. Conclusion. The capillaroscopy values and basal microcirculation values that we have obtained may be used in practically healthy children for comparison with such values in children with varied pathologies, which might be helpful in diagnosing various diseases and disorders at early stages and exercising control over treatment with selection of individual pharmacotherapy.
