Abstract
Electroencephalography (EEG) is recording of the brain’s electrical
activity over a period of time, as recorded from multiple electrodes placed on
the scalp. Electroencephalography (EEG) is one of the oldest, yet most
valuable, diagnostic and prognostic test in neonates. It has been used for
decades to objectively assess the neurological status of critically ill neonates
Amplitude-integrated electroencephalography (aEEG) is a bedside
neurophysiology tool that uses a limited number of channels to record raw
EEG signal that is then filtered, rectified, processed, and displayed on a
semilogarithmic amplitude and time-compressed scaled. Continuous aEEG
monitoring offers a possibility to directly monitor the functional state of the
brain over hours and days.
aEEG is used to evaluate :
The background activity is the dominant pattern of electrical activity
in the aEEG tracing. It is classified by the lower margin amplitude
and upper margin amplitude of the activity band
Seizures are a sudden, repetitive, evolving EEG pattern with a clear
beginning, middle and end with a minimum duration of 10 s.
Sleep-wake cycling refers to cyclic fluctuation in the amplitude and
degree of discontinuity as the neonate enters various stages of sleep
or wakefulness.
This study aimed to identify the role of amplitude integrated
electroencephalography (a-EEG) in neonates with different gestational ages,
diseases, circumstances.
