Церебральная тканевая оксиметрия (rSO2) может быть использована для оценки мозгового кровообращения. Ранее были проведены исследования церебральной тканевой оксиметрии при положении Тренделенбурга с углом наклона 30º, однако отсутствуют данные о rSO2 для угла наклона 45о.</p></sec><sec><title>Цель</title><p>Цель. Изучить влияние положения Тренделенбурга с углом наклона 45о в условиях карбоксиперитонеума на rSO2 и показатели гемодинамики.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведено одноцентровое проспективное описательное исследование среди пациентов (n = 30), которым была проведена робот-ассистированная лапароскопическая простатэктомия. Мы измеряли rSO2 слева и справа, центральное венозное давление (ЦВД), среднее артериальное давление (АДср), венозную сатурацию в пробах крови во временных точках: Т1 — после индукции анестезии и начала измерений; Т2 — 5 минут после позиционирования пациента в положение Тренделенбурга с углом наклона 45о; Т3 — 15 минут; Т4 — 30 минут; Т5 — после возвращения в горизонтальное положение. Оценку перфузии головного мозга проводили с помощью церебрального перфузионного давления (ЦПД).</p></sec><sec><title>Результаты</title><p>Результаты. rSO2 справа и слева в точках Т2, Т3 и Т5 значимо превышала показатели Т1. После позиционирования пациента в положение Тренделенбурга отмечено значимое увеличение АДср в точках Т2 и Т3, а также значимое увеличение ЦВД в Т2, Т3 и Т4 в сравнении с T1. ЦПД значимо снизилось по сравнению с T1 в точках Т3, Т4 и Т5, причем значения ЦПД не выходили за границы нормы.</p></sec><sec><title>Выводы</title><p>Выводы. Положение Тренделенбурга с углом наклона в 45º в совокупности с карбоксиперитонеумом сопровождается увеличением rSO2, АД и ЦВД.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Cerebral tissue oximetry (rSO2) can be used to assess cerebral circulation. Cerebral tissue oximetry studies have been performed in the Trendelenburg position (30º), but data for 45 o are not available.</p></sec><sec><title>Objective</title><p>Objective. To study the effect of the Trendelenburg position (45°) under carboxyperitoneum conditions on rSO2 and hemodynamic parameters.</p></sec><sec><title>Design and methods</title><p>Design and methods. A single-center, prospective, descriptive study was conducted among patients (n = 30) who underwent robot-assisted laparoscopic prostatectomy. We measured rSO2 on the left and right, central venous pressure (CVP), mean arterial pressure (MAP), venous saturation at points: T1 — after induction of anesthesia and start of measurements; T2 — 5 minutes after positioning the patient in the Trendelenburg position of 45o; T3 — 15 minutes; T4 — 30 minutes; T5 — after returning to a horizontal position. Cerebral perfusion was assessed using cerebral perfusion pressure (CPP).</p></sec><sec><title>Results</title><p>Results. rSO2 on the right and left at points T2, T3 and T5 significantly exceeded T1. There was a significant increase in BP mean at T2 and T3, as well as a significant increase in CVP at T2, T3 and T4 compared to T1. The CPP significantly decreased compared to T1 at points T3, T4 and T5.</p></sec><sec><title>Conclusions</title><p>Conclusions. The Trendelenburg position with a tilt angle of 45º in combination with carboxyperitoneum is accompanied by an increase in rSO2, blood pressure and CVP.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>карбоксиперитонеум</kwd><kwd>положение Тренделенбурга</kwd><kwd>церебральная тканевая оксиметрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>carboxyperitoneum</kwd><kwd>cerebral tissue oximetry</kwd><kwd>Trendelenburg position</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">Унгуряну Т.Н., Гржибовский А.М.
