Дексмедетомидин (высокоселективный агонист α2-адренорецепторов) используется для аналгоседации при различных вмешательствах. В некоторых работах было отмечено, что нагрузочная доза дексмедетомидина 1,0 мкг/кг/15 минут может приводить к уменьшению диаметра коронарных артерий как у здоровых волонтеров, так и у пациентов с ишемической болезнью сердца. Цель исследования – оценить влияние моно-анестезии дексмедетомидином на диаметр стентируемой артерии (проксимальнее и дистальнее места стеноза) при плановых эндоваскулярных стентированиях коронарных артерий. Материалы и методы. Проведено квазиэкспериментальное исследование «до и после». В исследовании с сентября 2021 г. по январь 2022 г. приняли участие 22 пациента. Проведено сравнение 27 показателей, так как пяти пациентам выполнено одномоментное стентирование двух коронарных артерий. Результаты. Диаметр проксимального отдела стентируемой артерии до нагрузочной дозы дексмедетомидина составлял 2,9 мм [2,5–3,4]; после нагрузочной дозы – 3,0 мм [2,5–3,4] (p = 0,6). Исходный диаметр дистального сегмента коронарной артерии – 2,2 мм [1,7–2,4], тогда как после нагрузочной дозы дексмедетомидина – 2,2 мм [2,0–2,5] (p = 0,001). Обсуждение. Несмотря на ряд ограничений данного исследования (факторы, влияющие на диаметр коронарных артерий, которые не были учтены) с определенной долей оптимизма можно говорить о меньшем влиянии нагрузочной дозы дексмедетомидина 0,5 мкг/кг/10 минут на диаметр просвета коронарных артерий. Заключение. В данном исследовании не было выявлено изменение проксимального сегмента коронарной артерии при применении нагрузочной дозы дексмедетомидина 0,5 мкг/кг/10 минут, но было зарегистрировано увеличение диаметра дистального отдела коронарных артерий при использовании указанной выше нагрузочной дозы дексмедетомидина.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. Dexmedetomidine (a highly selective α2-adrenergic agonist) is used for analgosedation in various interventions. Some studies have noted that a loading dose of dexmedetomidine 1.0 μg/kg/15 minutes can lead to a decrease in the diameter of the coronary arteries in both healthy volunteers and patients with coronary heart disease (CHD). The aim of the study was to evaluate the effect of monoanesthesia with dexmedetomidine on the diameter of the stented artery (proximal and distal to the site of stenosis) during elective endovascular stenting of the coronary arteries. Materials and methods. A quasi-experimental study "before and after" was carried out. The study included 22 patients from September 2021 to January 2022. A comparison of 27 indicators was carried out, since 5 patients underwent simultaneous stenting of 2 coronary arteries. Results. The diameter of the proximal section of the stented artery before the loading dose of dexmedetomidine was 2.9 mm [2.5–3.4]; after loading dose – 3.0 mm [2.5–3.4] (p = 0.6). The initial diameter of the distal segment of the coronary artery was 2.2 mm [1.7–2.4], while after a loading dose of dexmedetomidine it was 2.2 mm [2.0–2.5] (p = 0.001). Discussion. In this study, there was no change in the proximal segment of the coronary artery when using a loading dose of dexmedetomidine 0.5 mcg/kg/10 minutes. Whereas an increase in the diameter of the distal coronary arteries has been reported with the above loading dose of dexmedetomidine. Conclusion. Despite a number of limitations of this study (factors affecting the diameter of the coronary arteries that were not taken into account), with a certain degree of optimism, one can speak of a smaller effect of a loading dose of dexmedetomidine 0.5 μg/kg/10 minutes on the diameter of the lumen of the coronary arteries.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>плановое эндоваскулярное стентирование коронарных артерий</kwd><kwd>дексмедетомидин</kwd><kwd>анестезиологическое обеспечение</kwd><kwd>диаметр коронарных артерий</kwd></kwd-group><kwd-group xml:lang="en"><kwd>elective endovascular stenting of coronary arteries</kwd><kwd>dexmedetomidine</kwd><kwd>anesthetic management</kwd><kwd>diameter of coronary arteries</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">Scott-Warren V.
