Обоснование возможности применения мониторинга вариабельности ритма сердца при применении дексмедетомидина у пациентов с повреждением головного мозга различной этиологии.</p><p>Материал и методы исследования. В исследование включили 25 пациентов (мужчин — 14, женщин — 11, средний возраст — 58,2±1,81 лет), в период более 20-ти дней с последствиями: черепномозговой травмы (ЧМТ) (n=9; 36%); острого нарушения мозгового кровообращения (ОНМК) (n=4; 16%); аноксического повреждения головного мозга (n=6; 24%); субарахноидального кровоизлияния (САК) (n=6; 24%). Дексмедетомидин применяли при симпатической гиперактивности, исходя из показателей вариабельности ритма сердца (ВРС). Регистрировали следующие показатели: SI — стресс-индекс Баевского (индекс напряжения регуляторных систем — индекс напряжения) в нормализованных единицах (н. е.); SDNN — среднеквадратичное отклонение R-R кардиоинтервалов в мс; rMSSD — среднеквадратичное отклонение разности двух смежных отсчетов R-R кардиоинтервалов в мс; pNN50% — долю R–R кардиоинтервалов в процентах, отличающихся от предыдущего более чем на 50 мс; TP — общую мощность спектра частот в мсек2. Параметры ВРС регистрировали до инфузии дексмедетомидина (исходно), на 1–3-и; 4–5-е; 9–10-е; 15–20-е сутки применения лекарственного препарата. Симпатическую гиперактивность принимали в пределах значений для SDNN &lt; 13,31 мс; для RMSSD &lt; 5,78 мс; для pNN50% &lt; 0,110%; для SI &gt; 900 н. е. (нормализованных ед.); для TP &lt; 200 мс2; норму параметров ВРС принимали в пределах значений для SDNN [13,31–41,4мс]; для RMSSD [5,78–42,3 мс]; для pNN50% (0,110–8,1%); для SI (80–900 н. е.); для TP (200–2000 мс2).</p></sec><sec><title>Результаты</title><p>Результаты. Стартовая доза дексмедетомидина при симпатической гиперактивности составила у пациентов от 0,12 до 0,24 мкг/кг/час (средняя доза 0,16±0,01; суммарно 200 мкг/сутки). По цифровым данным ВРС эффективная доза дексмедетомидина ЭД50 составила 0,26±0,03 мкг/кг/час (суммарно за сутки 353,8 + 35,1мкг) и была достигнута на 9–10-й день применения дексмедетомидина.</p></sec><sec><title>Заключение</title><p>Заключение. Электрофизиологический нейромониторинг выявления функционального состояния автономной нервной системы повышает эффективность применения дексмедетомидина у пациентов с повреждением головного мозга различной этиологии.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim: to validate the use of heart rate variability monitoring during dexmedetomidine administration in patients with brain injury of various etiologies.</p></sec><sec><title>Material and methods</title><p>Material and methods. The study included 25 patients (14 male, 11 female, mean age 58.2±1.81 years) 20 and more days after traumatic brain injury (TBI) (n=9; 36%), acute stroke (n=4; 16%), anoxic brain injury (n=6; 24%), subarachnoid hemorrhage (SAH) (n=6; 24%). Dexmedetomidine was prescribed because of sympathetic hyperactivity as diagnosed by heart rate variability (HRV). The following indices were measured: SI (stress index, in normalized units [nu]), SDNN (standard deviation of all normal sinus RR intervals over 24 h, in ms), RMSSD (root-mean-square of successive normal sinus RR interval difference, in ms), pNN 50% (the percentage of successive normal sinus RR intervals &gt;50 ms), TP (total power of the frequency spectrum, in ms2). HRV parameters were determined prior to dexmedetomidine infusion (baseline), on days 1–3, 4–5, 9–10, 15–20 of drug administration. Sympathetic hyperactivity was diagnosed by determining following values: SDNN &lt; 13.31 ms, RMSSD &lt; 5.78 ms, pNN 50% &lt; 0.110%, SI &gt; 900 nu, and TP &lt; 200 ms2. Normal reference ranges for HRV parameters were as follows: SDNN (13.31–41.4 ms), RMSSD (5.78–42.3 ms), pNN5 0% (0.110–8.1%), SI (80–900 nu), and TP (200–2000 ms2).</p></sec><sec><title>Results</title><p>Results. The starting dose of dexmedetomidine for sympathetic hyperactivity was 0.12–0.24 µg/kg/hr (mean dose 0.16±0.01; total 200 µg/day). According to digital HRV data, the effective dose ED50 of dexmedetomidine was 0.26±0.03 µg/kg/hour (353.8±35.1 µg total per day) that was achieved on day 9–10 of drug administration.</p></sec><sec><title>Conclusion</title><p>Conclusion. Electrophysiological neuromonitoring of the autonomic nervous system function increases the efficacy of dexmedetomidine administration in patients with brain injury of various etiologies.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>симпатическая гиперактивность</kwd><kwd>автономная нервная система</kwd><kwd>вариабельность ритма сердца</kwd><kwd>дексмедетомидин</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sympathetic hyperactivity</kwd><kwd>autonomic nervous system</kwd><kwd>heart rate variability</kwd><kwd>dexmedetomidine</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">Mahmoud M., Mason K.P.
