How do you interpret neonatal EEG?

Similar to adult EEG, an orderly approach to visual analysis is necessary to effectively interpret neonatal EEG. The basic organization of the background rhythm should include an inspection of the EEG continuity and discontinuity, symmetry, synchrony, amplitude, reactivity, and morphology and composition of graphoelements.

What are the earliest vestiges of EEG activity during pregnancy?

Electroencephalogr Clin Neurophysiol 1980;49:618–625.) The earliest vestiges of EEG activity are believed to arise after the 8th week of gestation where the EEG tracing appears as a completely discontinuous recording in which brief periods of electric activity (“bursts”) are interrupted by periods of quiescence (“interburst” intervals or IBIs).

How many electrodes are in a neonatal EEG montage?

Neonatal EEG montages. A: Restricted 10–20 system using nine electrodes; B: Full 10–20 system of electrode placement using 17 electrodes. Note the bipolar derivations: anteroposterior right and left, as well as a coronal run including the central midline

How long does it take to record a neonatal EEG?

Neonatal EEG recording should last at least 2 to 3 hours to capture awake and all sleep stages. Neonatal EEG is typically displayed with a longer time interval on the screen (a faster “paper speed” of 15 mm/s) producing a more compressed-appearing recording.

What is an example of neonatal EEG interpretation?

An example is a 4-week-old baby born at 30 weeks GA would have a CA of 34 weeks. Taking into account the CA, a neonate is a newborn infant with age <4 weeks. The definitions of preterm, near-term, and term are also important to become familiar with for neonatal EEG interpretation.

What is the developmental EEG?

The Developmental EEG: Premature, Neonatal, Infant, and Children - Electroencephalography (EEG): An Introductory Text and Atlas of Normal and Abnormal Findings in Adults, Children, and Infants - NCBI Bookshelf The neonatal EEG has some very different clinical considerations for recording and interpretation.

What is the best way to record neonatal EEG?

Polygraphic registrations are the rule while recording neonatal EEG[3]. Simultaneous recording of video is also becoming a standard practice. Video helps in assessing clinical seizures and in recognizing artifacts.

What is a normal background pattern on an EEG?

The normal term EEG is continuous, symmetrical and synchronous in the awake and active sleep states, with occasional sharp waves from a variety of regions of the brain and sleep wake cycling seen. There is no universally accepted grading system to classify abnormal neonatal EEG background patterns.

How long does it take to record EEG?

These are connected by wires to an EEG recording machine. Routine EEG recordings usually take 20 to 40 minutes, although a typical appointment will last about an hour, including some preparation time at the beginning and some time at the end. Other types of EEG recording may take longer. A routine EEG recording lasts for about 20 to 40 minutes.

What is the background of a neonatal EEG?

The background of a neonatal EEG is grossly broken down into awake, quiet sleep, and active sleep states. Awake is marked simply by the presence of the eyes being open, and asleep by the eyes being closed.

What is the duration of multi-channel EEG in neonates in the NICU?

Multi-channel EEG was recorded from 79 term neonates admitted to the NICU at the Helsinki University Hospital. The median recording duration was 74 min (IQR: 64 to 96 min).

How many electrodes do you need for long term EEG?

Most current long-term EEG monitoring uses 2 to 4 recording electrodes, and the international gold standard for neonatal EEG includes only 8–10 recording electrodes. We have collected neonatal EEG routinely with the international 10–20 system to improve the spatial resolution of cerebral events29,30.
