Most publications aimed at analyzing brain bioelectrical activity in post-anoxic conditions focus primarily on disturbances in the acute phase of post-anoxic encephalopathy (PAE). The dynamic changes in bioelectrogenesis mechanisms during subsequent disease progression are described in few publications reporting contradictory results. Motor phenomena recorded during PAE in children can be present simultaneously or alternate, creating difficulties in their interpretation and selection of pharmacotherapy. Therefore, a retrospective pilot study was needed to assess clinical significance of videoelectroencephalographic monitoring (VEEM) and the impact of its results on therapeutic strategy and prognosis for recovery in patients with chronic post-anoxic myoclonus (PAM).</p></sec><sec><title>Objective</title><p>Objective: Тo assess extent of VEEM sufficient to determine the level of myoclonus generation in children with PAE.</p></sec><sec><title>Material and methods</title><p>Material and methods. The retrospective study included 10 children with post-anoxic conditions of different genesis (freshwater drowning, mechanical asphyxia, cardiopulmonary resuscitation during septic shock) who underwent rehabilitation treatment at the Research Institute of Emergency Pediatric Surgery and Trauma – Dr. Roshal’s Clinic in the years 2020–2023. Nine of the examined subjects underwent VEEM according to a standardized protocol; 1 child received VEEM in another medical institution.</p></sec><sec><title>Results</title><p>Results. Chronic PAM was present in 2 children examined. In one case, there was a myoclonus of different levels of generation combined with epileptiform seizures and generalized dystonia, in the other case – myoclonus recorded along with generalized dystonia. In both cases, the use of clonazepam improved PAM clinical manifestations.</p></sec><sec><title>Conclusion</title><p>Conclusion. Patients with history of PAM are required to receive an extended VEEM added with myographic channels for conducting differential diagnostics with motor phenomena, to clarify generation level for chronic postanoxic myoclonus, if any, and select pharmacotherapy strategy.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Актуальность</title><p>Актуальность. Большинство публикаций, посвященных анализу биоэлектрической активности головного мозга при постаноксических состояниях, рассматривают преимущественно нарушения в остром периоде постаноксической энцефалопатии (ПАЭ). Проблему динамических изменений механизмов биоэлектрогенеза при дальнейшем развитии заболевания описывают единичные публикации, а полученные результаты носят противоречивый характер. Моторные феномены, регистрируемые при ПАЭ у детей, могут присутствовать одновременно или сменять друг друга, создавая сложности в их интерпретации и подборе фармакотерапии. С целью определения клинической значимости видеоэлектроэнцефалографического мониторинга (ВЭЭМ) и влияния его результатов на терапевтическую стратегию и прогноз восстановления пациентов с хроническим постаноксическим миоклонусом (ПАМ) возникла необходимость проведения ретроспективного пилотного исследования.</p></sec><sec><title>Цель</title><p>Цель: определить объем ВЭЭМ, достаточный для оценки уровня генерации миоклонуса у детей с ПАЭ.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В ретроспективное исследование вошли 10 детей с постаноксическими состояниями разного генеза (утопление в пресной воде, механическая асфиксия, сердечно-легочная реанимация на фоне септического шока), проходивших реабилитационное лечение на базе ГБУЗ «Научно-исследовательский институт неотложной детской хирургии и травматологии – Клиника доктора Рошаля» в период 2020–2023 гг. У 9 из них проведен ВЭЭМ по стандартизированному протоколу, у 1 ребенка ВЭЭМ выполнялся на базе стороннего лечебно-профилактического учреждения.</p></sec><sec><title>Результаты</title><p>Результаты. Хронический ПАМ присутствовал у 2 детей из группы. В одном случае отмечалось сочетание миоклонуса разного уровня генерации с эпилептиформными и генерализованными дистониями, в другом – миоклонуса с генерализованными дистониями. В обоих наблюдениях применение клоназепама позволило улучшить клинические проявления ПАМ.</p></sec><sec><title>Заключение</title><p>Заключение. У пациентов с ПАЭ в анамнезе необходимо проведение расширенного ВЭЭМ с добавлением миографических каналов для дифференциальной диагностики моторных феноменов, уточнения уровня генерации хронического ПАМ при его наличии и подбора фармакотерапии.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>постаноксическая энцефалопатия</kwd><kwd>постаноксический миоклонус</kwd><kwd>видеоэлектроэнцефалографический мониторинг</kwd></kwd-group><kwd-group xml:lang="en"><kwd>post-anoxic encephalopathy</kwd><kwd>post-anoxic myoclonus</kwd><kwd>video-electroencephalographic monitoring</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">Asghar A., Barnes B., Aburahma A., et al.
