EEG Dynamics in Children Before, During and After General Anesthesia
Authors' conclusion
The EEG readouts differ across age groups
Study context
- Population
- Children aged 1 month to 8 years under GA, Charité-Campus Virchow Klinik
- Participants
- 147 frontal EEGs
- Exposure
- Perioperative frontal EEG signatures across four age groups
- Outcome
- Perioperative frontal EEG frequency bands
Methodological detailssingle-centre, Narcotrend Monitor; raw EEG analysed in frequency bands
- Single-centre
- Narcotrend Monitor; raw EEG analysed in frequency bands
Main finding
As reported in the abstract
- Delta activity predominant in all age groups already awake before induction, with step increase at loss of consciousness, more pronounced in older children
- Intraoperatively, alpha and beta activity emerge at age 6 months and are greater in older age groups
- Infants (0-5 months) retain high delta activity intraoperatively
- At return of consciousness, faster frequencies gradually decrease and delta activity again predominates in all age groups
Observational data: associations, not effects.
