The aEEG machine or software then processes the raw EEG tracing to facilitate its interpretation. The raw recording is filtered, removing signal with frequencies below 2 Hz and above 60 Hz. The filter parameters are designed to eliminate artifact, but the high pass 2 Hz filter can also eliminate normal and pathologic features, including low-frequency seizures. Visual and quantitative assessment of the aEEG/EEG background. The aEEG/EEG background scores were significantly lower in infants with poor outcome at 0–12, 12–24, 24–48 and 48–72 h as compared to those with good outcome (p = 0.023, p = 0.036, p ≤ 0.001, and p = 0.003, respectively).

The brain’s electrical activity fluctuates from second to second, but routine EEGs provide only a 20-40 minute sample of this activity. 2015-06-02 2020-06-02 A study in the Journal of Child Neurology comparing the diagnostic yield of aEEG interpreted at the bedside, aEEG interpreted by an expert, and cEEG determined that “bedside amplitude-integrated electroencephalogram (EEG) possesses low sensitivity and specificity for detecting seizures compared with conventional EEG and may be prone to error in seizure classification in neonates.” Amplitude Integrated EEG - Persyst Amplitude Integrated EEG (aEEG) displays amplitude characteristics of the EEG signal.

Use of CCFM EEGDigiTrack CCFM device allows for many hours of monitoring EEG of the left and right cerebral hemisphere, as well as evaluation of its condition during such events as: desaturation, bradycardia, tachycardia, convulsions, sleep, postanesthetic recovery and other.

Evaluation of SEPs in asphyxiated newborns using a 4-electrode

Evans et al, ADC Fetal Neonatal Ed 2010 2-ch aEEG vs 12-ch EEG (44 STEP 5: Evaluate the aEEG pattern for Symmetry (if more than 1 channel is available for comparison) _____ STEP 6: Identify Suspicious Areas and examine EEG closely. Be sure to look for: Evidence of EEG Seizure Activity (spike-wave, repetitive patterns on the EEG) Therefore, in the last decades, amplitude-integrated EEG (aEEG), previously referred to as Cerebral Function Monitor (CFM), has become popular as a simplified method to perform a continuous brain monitoring based on few channels (usually from 1 to 3 channels) (Boylan et al., 2013). The electrocortical background pattern (BG) in the amplitude‐integrated electroencephalogram (aEEG)/EEG has proved to be one of the best early predictors of outcome in term asphyxiated infants (2). However, less is known about the long‐term predictive value of early aEEG/EEG in VPT infants (3 - 6). 2-ch aEEG/EEG vs 1-ch aEEG/EEG (N=34 infants with sz; 18 unilateral injury, 14 bilateral injury, and 2 no injury 2-ch aEEG/EEG: detected 18% more sz + more sz on ipsilateral side in 79% of infants with unilateral injury; and 39% more sz in infants with diffuse brain damage.

Author information: (1)Boston Children's Hospital, Boston, MA, United States. EEG/aEEG findings may differ substantially among infants, even within infants with variants in a single gene. Unusual EEG/aEEG findings, such as downward seizure patterns on aEEG, can be found. 2021-04-09 · When stratified by indication for EEG, hypoxic episode (n=14) or suspected seizures (n=33), similar sensitivity for presence of seizure (80%) was noted by aEEG and sEEG.
