amplitude-integrated electroencephalography
Also written as: aEEG — Amplitude-integrated Electroencephalography
A simplified continuous brain monitoring technique that displays compressed EEG activity to assess neurological status and seizure activity in newborns.
Full Definition
Amplitude-integrated electroencephalography (aEEG) is a simplified, continuous brain monitoring method used in neonatal intensive care to assess neurological function and detect seizures in critically ill newborns. The technique uses fewer electrodes than conventional EEG and displays brain activity as compressed, color-coded traces that can be interpreted by bedside clinicians. aEEG monitoring is particularly valuable for detecting subclinical seizures, assessing background brain activity patterns, and monitoring recovery from hypoxic-ischemic encephalopathy. The continuous nature of aEEG monitoring allows for real-time assessment of neurological status and can guide treatment decisions, particularly regarding anti-seizure medications and neuroprotective interventions.
Usage
Usage note: Often abbreviated as aEEG; distinguish from conventional EEG in documentation and interpretations.
