Кожной микроциркуляции присуща естественная пространственная и временная вариабельность перфузии, обусловленная особенностями строения микроциркуляторного русла и влиянием регуляторных факторов.</p><p>Цель – оценить пространственную гетерогенность и междневную индивидуальную воспроизводимость показателей лазерной допплеровской флоуметрии (ЛДФ) с температурными пробами у здоровых испытуемых.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование был включен 51 здоровый доброволец (ж/м – 35/16; возраст 25 [24; 26] лет). Протокол исследования предусматривал 2 дня измерения с интервалом 3–7 дней. У каждого испытуемого регистрировались основные антропометрические, физиологические параметры и микроциркуляция в коже методом ЛДФ на тыльной и вентральной стороне предплечья в состоянии покоя (Мбазал), при охлаждении (Мохл) и нагревании (Мнагр). Сравнение величин на тыльной и вентральной стороне предплечья, а также оценка динамики кожной перфузии в ходе температурных проб проводились при помощи критерия Вилкоксона для зависимых переменных. Междневную индивидуальную воспроизводимость перфузии кожи определяли с использованием коэффициента внутриклассовой корреляции (ICC) и коэффициента вариации (CV, %). Данные представлены в виде медианы и межквартильного интервала.</p></sec><sec><title>Результаты</title><p>Результаты. В коже тыльной стороны предплечья показатели микроциркуляции Мбазал (7,8 [4,8; 11,1]), Мохл (7,5 [4,8; 10,5]) и Мнагр (7,5 [4,2; 10,9]) статистически значимо (p&lt;0,001) были ниже, чем на вентральной стороне: Мбазал 10,4 [5,9; 13,0], Мохл 9,9 [5,6; 13,3], Мнагр 9,5 [5,2; 12,5]. При оценке динамики кожной перфузии в ходе температурных проб выявлены статистически значимые изменения кожного кровотока, как при охлаждении, так и при нагревании на обеих сторонах предплечья (p&lt;0,01 vs Мбазал). Наилучшая междневная воспроизводимость была у показателей Мохл (CV=8,3 %, ICC=0,56) и Мнагр (CV=19,9 %, ICC=0,563) на тыльной стороне предплечья.</p></sec><sec><title>Заключение</title><p>Заключение. В состоянии покоя и при температурных пробах перфузия кожи, оцененная методом ЛДФ, статистически значимо выше на вентральной стороне предплечья по сравнению с тыльной. Междневная воспроизводимость ЛДФ при тепловой и холодовой пробах выше на коже тыльной стороны предплечья, чем на вентральной.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Skin microcirculation is characterized by natural spatial and temporal variation of perfusion due to the structure of the cutaneous microvasculature and the influence of regulatory factors.</p></sec><sec><title>Objective</title><p>Objective. To evaluate spatial heterogeneity of skin perfusion and inter day individual reproducibility of Laser Doppler flowmetry (LDF) with local thermal tests in healthy volunteers.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included 51 healthy volunteers (female/man – 35/16; age 25 [24; 26] years). The study protocol included 2 days of measurements with an interval of 3–7 days. After measuring basic anthropometric and physiological parameters, all subjects underwent LDF on the dorsal and ventral side of the forearm at rest (Mbaseline), then during cooling (Mcold) and heating (Mheat). Comparison of variables on the dorsal and ventral sides of the forearm, as well as assessment of the dynamics of skin perfusion during thermal tests were carried out using the Wilcoxon matched pairs test. The inter-day individual reproducibility of skin perfusion was measured by using the intraclass correlation coefficient (ICC) and coefficient of variation (CV, %). Data are expressed as median and interquartile range.</p></sec><sec><title>Results</title><p>Results. Mbaseline (7.8 [4.8; 11.1]), Mcold (7.5 [4.8; 10.5]) and Mheat 7.5 [4.2; 10.9] in the skin of the dorsum of the forearm were statistically significantly lower (p&lt;0.001) than on the ventral side: Mbaseline 10.4 [5.9; 13.0], Mcold 9.9 [5.6; 13.3], Mheat 9.5 [5.2; 12.5]. When assessing the dynamics of skin perfusion during the thermal tests, statistically significant changes in skin blood flow were revealed, both during cooling and heating on both sides of the forearm (p&lt;0.01 vs Mbaseline). Mcold (CV=8.3 %, ICC=0.56) and Mheat (CV=19.9 %, ICC=0.563) on the dorsal forearm had the best inter-day reproducibility.</p></sec><sec><title>Conclusion</title><p>Conclusion. Skin perfusion, assessed by LDF is statistically significantly higher on the ventral side of the forearm compared to the dorsum . The inter-day reproducibility of LDF during local heating and cooling tests is higher on the skin of the dorsal side of the forearm than on the ventral side.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>микрогемоциркуляция кожи</kwd><kwd>лазерная допплеровская флоуметрия</kwd><kwd>температурные функциональные тесты</kwd><kwd>пространственная гетерогенность</kwd><kwd>междневная воспроизводимость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>skin microcirculation</kwd><kwd>Laser Doppler flowmetry</kwd><kwd>thermal functional tests</kwd><kwd>spatial heterogeneity</kwd><kwd>inter-day reproducibility</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Крупаткин А.И., Сидоров В.В.
