Catatonia is a complex neuropsychiatric syndrome characterized by motor and behavioral disturbances, which can complicate both psychiatric and medical conditions. Diagnosing catatonia in the Intensive Care Unit (ICU) can be challenging due to symptom overlap with other conditions, such as delirium. Electroconvulsive therapy (ECT) may be considered in certain cases, particularly when standard treatments fail, though its use in ICU settings is rare due to concerns about patient stability and procedural risk. We present the case of a 43-year-old male, admitted for a manic episode, who was transferred to the ICU following a cardiorespiratory arrest and subsequently treated with ECT for malignant catatonia.

Keywords: cardiorespiratory arrest; catatonia; critical illness; electroconvulsive therapy; intensive care unit; malignant catatonia; mania.

卡塔托尼亚是一种复杂的神经精神综合征，其特征是运动和行为障碍，这些症状可能会影响精神病和医学条件的诊断。在重症监护室（ICU）中诊断卡塔托尼亚具有挑战性，因为其症状与其他情况如谵妄有重叠。电抽搐治疗（ECT）可能在某些情况下被考虑使用，特别是当标准治疗方法无效时，尽管由于对患者稳定性和程序风险的担忧，在ICU环境中的应用较为罕见。我们介绍了一名43岁男性患者的案例，该患者因躁狂发作住院，并在接受心脏和呼吸骤停后的ICU治疗过程中接受了电抽搐治疗以应对恶性卡塔托尼亚。
