Posthypoxic myoclonus (Lance-Adams' syndrome) is a rare complication of cardiorespiratory arrest. It has a better prognosis than other movement disorders secondary to brain ischaemia. We report a case of posthypoxic myoclonus in a 66-year-old woman after acute myocardial infarction and cardiopulmonary arrest. She had action and intention myoclonus, and these movements were also initiated by acoustic and pain stimuli. The origin of the myoclonus was probably subcortical, and it improved with clonazepam 2 mg t.i.d. We emphasize that early diagnosis is necessary in intensive care units in order to avoid misinterpretation of this syndrome and to start appropriate treatment.
缺氧后肌阵挛（兰斯-亚当斯综合征）是心肺骤停的一种罕见并发症。它的预后比脑缺血继发的其他运动障碍要好。我们报告一例66岁女性在急性心肌梗死和心肺骤停后发生缺氧后肌阵挛的病例。她有动作性和意向性肌阵挛，这些动作也可由听觉和疼痛刺激引发。肌阵挛的起源可能在皮层下，服用氯硝西泮2毫克每日三次后病情有所改善。我们强调，重症监护病房有必要进行早期诊断，以避免对该综合征的误诊并开始适当治疗。
