SE significantly worsens neurological prognosis and increases the likelihood of fatal outcomes. In most cases, epileptic seizures and status epilepticus in intensive care unit patients lack clinical manifestations and are detected exclusively through electroencephalography (EEG). In this study, we present a series of clinical observations demonstrating the transformation of SE from clinical to electrographic manifestations during anticonvulsant therapy in children with cyanotic congenital heart defects during the postoperative period. We emphasize the critical importance of EEG in managing SE in pediatric intensive care settings.</p></abstract><trans-abstract xml:lang="ru"><p>Эпилептический статус (ЭС) является тяжёлым осложнением кардиохирургических операций, направленных на коррекцию врождённых пороков сердца цианотического типа у детей. Наличие ЭС значимо ухудшает неврологический прогноз и увеличивает вероятность летального исхода. В большинстве случаев эпилептические приступы и статус у пациентов в отделении реанимации не имеют клинических проявлений и регистрируются исключительно при проведении электроэнцефалограммы. В данной работе мы демонстрируем серию клинических наблюдений трансформации ЭС из клинического в электрографический на фоне противосудорожной терапии у детей с цианотическими врождёнными пороками сердца в постоперационном периоде. Мы акцентируем внимание на важности использовании электроэнцефалографии в купировании ЭС в педиатрической реанимации.</p></trans-abstract><kwd-group xml:lang="en"><kwd>electroencephalography</kwd><kwd>status epilepticus</kwd><kwd>congenital heart defect</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>электроэнцефалография</kwd><kwd>эпилептический статус</kwd><kwd>врождённый порок сердца</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Саперова Е.В., Вахлова И.В.
