Technical standards for recording and interpretation of neonatal electroencephalogram in clinical practice.

Bottom Line: Neonatal electroencephalogram (EEG), though often perceived as being difficult to record and interpret, is relatively easy to study due to the immature nature of the brain, which expresses only a few well-defined set of patterns.The EEG interpreter needs to be aware of the maturational changes as well as the effect of pathological processes and medication on brain activity.It gives valuable information for the treatment and prognostication in encephalopathic neonates.

ABSTRACT
Neonatal electroencephalogram (EEG), though often perceived as being difficult to record and interpret, is relatively easy to study due to the immature nature of the brain, which expresses only a few well-defined set of patterns. The EEG interpreter needs to be aware of the maturational changes as well as the effect of pathological processes and medication on brain activity. It gives valuable information for the treatment and prognostication in encephalopathic neonates. In this group, serial EEGs or EEG monitoring often gives additional information regarding deterioration/improvement of the brain function or occurrence of seizures.

Burst suppression (BS) pattern in severe birth asphyxia. Severely suppressed background activity (<5 μV) with intermittent bursts of 10–20 μV. As opposed to trace discontinu [Figure 5], no EEG activity is discernible during the discontinuous periods. aEEG trend of 30 minutes shows BS and absent variability. Mean band width of the suppressed periods is <2 μV

Mentions: Abnormalities of voltage seen in encephalopathic neonates, in increasing order of severity are: a) discontinuous EEG [Figure 5], b) continuous low-voltage EEG (voltage < 10 μV throughout the record), c) burst suppression pattern (BS) [Figure 6], and d) an isoelectric EEG or a ‘flat trace’ (voltage consistently < 5 μV).
