다국어 초록 (Multilingual Abstract)

Hypoxic myoclonus is usually a sign of unfavourable prognosis in cardiac arrest survivors. No single specific factor was yet consistently predictive of myoclonus or status epilepticus accompanying post-cardiac arrest status. The aim of this study was to investigate characteristics and the predicting factors of myoclonus in patients who recovered from cardiac arrest. A single center, retrospective study was performed from January 2011 to December 2013. Total of 177 patients who were over 18 years of age and who survived longer than 72 hours after cardiac arrest were enrolled. Patients were divided into two groups according to the development of myoclonus. Individual characteristics, information related to cardiac arrest and post-cardiac arrest status, method of evaluation and treatment, and the Cerebral Performance Category (CPC) score were collected. Of all patients, 42 were assigned to the myoclonus group and 135 to the non-myoclonic group. 40 patients (95.2%) of myoclonic group presented with generalized myoclonus. The asphyxia, as a presumed cause of arrest, was statically significant variables of myoclonus development after cardiac arrest (p=0.010). Initial arrest rhythm, laboratory test, therapeutic hypothermia was not associated with the development of myoclonus. Myoclonic group significantly showed tendency to increase rate of poor neurologic outcome (CPC 3 to 5) comparing to non-myoclonic group (p<0.00). The asphyxia as a cause of arrest may be single early predictor for the development of hypoxic myoclonus in the post-cardiac arrest patients.
