Answer

Generalized myoclonus in comatose survivors after CPR implies a poor prognosis despite improvement of the critical care of patients. [37] This transient, self-limited phenomenon reflects dysfunction of lethally damaged neurons. Propofol often controls myoclonus but does not change the underlying condition. Clinical, pathologic, and electroencephalographic (EEG) findings indicate that these patients die of severe hypoxic-ischemic damage. Abnormal EEG patterns, especially burst suppression EEG (BS-EEG) and alpha-coma EEG, are seen in these patients. The EEG abnormalities include BS-EEG, generalized epileptiform discharges, alpha-coma EEG. [38]
