Conventional multi-channel CEEG and aEEG monitoring. a, b aEEG monitoring demonstrated repetitively abrupt rises in the minimum and maximum amplitude on the activity band although the patient was treated with intravenous midazolam and pentobarbital. c, d aEEG showed the seizures were controlled after the maintenance dose (3 mg/kg/h) of propofol was given, while a few hours later, SE reappeared and then the maintenance dose of propofol was increased to 5 mg/kg/h. e As dosage of propofol was reduced gradually, continuous aEEG showed SE again. f On the 7th day of KD, aEEG showed that seizures were controlled again and the background of aEEG returned to the normal pattern with sleep–wake cycling
