Objective: To evaluate the feasibility of using amplitude-integrated electroencephalogram (aEEG) to identify epileptic seizures by physicians and nurses in pediatric intensive care unit (PICU) independently. Method: Six testees (two PICU physicians versus one EEG physician and two PICU nurses versus one EEG technician) accepted a short-term training, then interpreted aEEG in a single blinded way. These aEEG recordings with synchronous VEEG monitoring were done from January 2013 to May 2015 in PICU. The testees should recognize and mark both the seizure type and the seizure duration from the two-channel recorder (C3/C4) of aEEG (short-term seizure or status epilepticus (SE))...

AIM: Limited two-channel electroencephalography (EEG) and amplitude-integrated EEG (aEEG) monitorings are being increasingly used; however, these measurements have not been compared with polysomnographic monitoring, the gold standard for determining infant sleep states. We aimed to determine the accuracy of two-channel EEG and aEEG recordings in defining sleep states and wakefulness in term infants compared to polysomnographic monitoring. METHODS: Sleep was assessed in eight healthy term born infants (mean: 34 ± 3 days), using simultaneous polysomnography (Compumedics S-Series) and a two-channel EEG monitor (Brainz BRM2)...

Therapeutic hypothermia (TH) is now considered a standard in tertiary NICUs. Amplitude-integrated electroencephalography (aEEG) is an important adjunct to this therapy and is gaining acceptance for use on the neonatal population. It can be easily incorporated into practice with appropriate education and training. Current publications are lacking regarding nursing care of neonatal patients undergoing th with the use of aEEG. This article presents a broad educational program as well as novel teaching tool for neonatal nurses caring for this population...

BACKGROUND: The early prediction of neurological outcomes in postcardiac arrest patients treated with therapeutic hypothermia (TH) remains challenging. Amplitude-integrated electroencephalography (aEEG) is a type of quantitative EEG. A particular cutoff time from the return of spontaneous circulation (ROSC) to the recovery of a normal aEEG trace for predicting a good neurological outcome has not yet been established. The purpose of the present study was to examine the relation between neurological outcomes and the continuous normal voltage (CNV) recovery time in adult comatose survivors of cardiac arrest treated with TH and identify the recovery time cutoff for predicting a good neurological outcome...

The development and optimization of protocols using simultaneous video recording alongside long-term electroencephalography (EEG), such as ambulatory EEG (AEEG), expanded the range of available techniques for the investigation of paroxysmal clinical events. In particular, video-AEEG has received increasing attention over the last few years because of its potential to further improve diagnostic utility in the differential diagnosis between epileptic and nonepileptic seizures. We retrospectively evaluated 88 video-AEEG studies in order to assess the diagnostic utility of video-AEEG in 87 patients consecutively referred to a neurophysiology department...
