Abstract
Hypoxic myoclonus, also known as Lance Adams syndrome, is a rare syndrome that results from the serious brain damage caused by cerebral hypoxia that often follows cardiopulmonary resuscitation. This current case report describes two patients with post-hypoxic myoclonus, both of whom received cardiopulmonary resuscitation. The neurological symptoms of these two patients were significantly improved by the administration of clonazepam and sodium valproate sustained-release tablets. The report presents a literature review detailing the pathogenesis, diagnosis and treatment of Lance Adams syndrome. The timely diagnosis and treatment of Lance Adams syndrome can significantly improve the quality of life of patients. Valproic acid, clonazepam and other antiepileptic drugs can be used. Whether levetiracetam is effective for cortical myoclonus requires further clinical study.
