This method (Narcotrend®) allows for adjusting the dosages of anaesthetics to the patients’ age, gender and general physical condition. The Narcotrend (MonitorTechnik, Bad Bramstedt, Germany) is an EEG monitor designed to measure the depth of anaesthesia.

It has been developed at the University Medical School of Hannover, Germany, has been commercially available for over 10 years and has meanwhile received US Food and Drug Administration approval and is included in the NICE guidelines.

The Narcotrend algorithm is based on pattern recognition of the raw electroencephalogram (EEG) and classifies the EEG traces into different stages from A (awake) to F (increasing burst suppression down to electrical silence).

The raw EEG signal can be recorded by standard electrocardiogram electrodes for single- and double-channel registration.

The Narcotrend monitor provides a vast amount of information: the actual Narcotrend stage and index, the trend (‘cerebrogram’), the raw EEG signal and a power spectrum and several derived EEG parameters.
