The pathogenesis of sepsis is based on an excessive inflammatory response of the body. Several studies have reported the inhibitory effect of lidocaine on neutrophilic granulocytes.</p> <p><bold><italic>AIM:</italic></bold> This study aimed to analyze the effect of lidocaine on the oxidative activity of phagocytes.</p> <p><bold><italic>MATERIALS AND METHODS: </italic></bold>Blood from 16 healthy donors was used in this study. Leukocyte mass was extracted using spontaneous sedimentation. Half of the leukocyte samples were incubated in buffered physiological saline with lidocaine. The other half of the leukocyte samples were incubated in physiological saline without lidocaine. The generation of ROS was studied using two methods. Method 1 included a nitro blue tetrazolium (NBT) test), which is based on the ability of ROS to reduce NBT to insoluble diformazan. Method 2 was based on the chemiluminescence reaction. A culture of <italic>S. Aureus</italic> was used to induce the production of ROS.</p> <p><bold><italic>RESULTS: </italic></bold>NBT test revealed a decrease in the oxidative activity of leukocytes in the presence of lidocaine by 18% (<italic>p </italic>&lt;0.05). The study of luminol-dependent chemiluminescence of leukocyte suspension in the presence of lidocaine revealed a significant 2-fold decrease in both spontaneous and stimulated respiratory activity of cells.</p> <p><bold><italic>CONCLUSIONS:</italic></bold> After incubation with lidocaine, phagocytes generated ROS to a significantly lower extent. However, their complete blockade was not recorded. This property of lidocaine may be used in clinical practice to treat an excessive inflammatory response in sepsis.</p></abstract><trans-abstract xml:lang="ru"><p><bold><italic>Обоснование.</italic></bold> Избыточная выработка активных форм кислорода лейкоцитами способна вызывать повреждение собственных тканей. Чрезмерная воспалительная реакция организма лежит в основе патогенеза сепсиса. В ряде исследований сообщается об угнетающем влиянии лидокаина на нейтрофильные гранулоциты.</p> <p><bold><italic>Цель.</italic></bold> Целью исследования явилось изучение влияния лидокаина на окислительную активность фагоцитов.</p> <p><bold><italic>Материал и методы.</italic></bold> Для исследования использовалась кровь от 16 здоровых доноров. Лейкоцитарная масса выделялась с помощью спонтанной седиментации. Половина образцов лейкоцитов инкубировалась в забуферированном физиологическом растворе с лидокаином. Другая половина образцов лейкоцитов инкубировалась в физиологическом растворе без лидокаина. Генерация активных форм кислорода изучалась с помощью двух методов.</p> <p>Первый метод включал в себя постановку нитросинего теста (НСТ-тест). В основе данного теста лежит способность активных форм кислорода восстанавливать нитросиний тетразолий в нерастворимый диформазан. Второй метод основывался на реакции хемилюминесценции. Для индукции выработки активных форм кислорода использовалась культура St. Аureus.</p> <p><bold><italic>Результаты.</italic></bold> Нитросиний тест выявил снижение окислительной активности лейкоцитов в присутствии лидокаина на 18% (<italic>p</italic> &lt;0,05). Исследование люминолзависимой хемилюминесценции лейкоцитарной взвеси в присутствии лидокаина выявило достоверное снижение как спонтанной, так и стимулированной респираторной активности клеток в 2 раза.</p> <p><bold><italic>Выводы.</italic></bold> Фагоциты после инкубации с лидокаином достоверно меньше генерировали активные формы кислорода. Однако их полной блокады не зафиксировано. Данное свойство лидокаина возможно найдёт своё клиническое применение для лечения чрезмерной воспалительной реакции при сепсисе.</p></trans-abstract><kwd-group xml:lang="en"><kwd>lidocaine</kwd><kwd>reactive oxygen species</kwd><kwd>leukocytes</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>лидокаин</kwd><kwd>активные формы кислорода</kwd><kwd>лейкоциты</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Ovechkin AM, Becker AA.
