[Neuromonitoring in children - how deep does my patient sleep?]

The electroencephalogram (EEG) of wakefulness, sleep, and anaesthesia changes during childhood. Especially marked are the changes during the first year of life. In the second half of the first year, in most children EEG stages can be classified visually and automatically during anaesthesia which are similar to those observed in older children. In the first months of life, the EEG of anaesthesia is less differentiated, but it is still useful in patient monitoring during anaesthesia.
