Anaesthesia Made to Measure

Automatic assessment of the EEG during anaesthesia and sedation

Hypnotic drugs alter the electrical brain activity which can be recorded as electroencephalogram (EEG). An automatic classification of the EEG supports an individually adjusted dosing of anesthetics.

In an interdisciplinary cooperation, a method for the automatic classification of EEGs recorded during anaesthesia or intensive care was developed. This method (Narcotrend^®) allows for adjusting the dosages of anaesthetics to the patients' age, gender and general physical condition. During anaesthesia, this method helps to avoid EEG stages which are associated with an increased risk of awareness. On the other hand, overdosages can be avoided.
