Fig 1 Narcotrend-classification and BIS during maintenance of anaesthesia. Data are given as a percentage of the EEG levels calculated as grand means of 20 s intervals from 3 min after skin incision until 5 min before skin closure. The target level was defined as Narcotrend stages D2–E0. British Journal of Anaesthesia 2007 99, 686-693DOI: (10.1093/bja/aem231) Copyright © 2007 British Journal of Anaesthesia Terms and Conditions
Fig 2 Histograms showing the mean Narcotrend classification during the time of intubation, of skin incision, and during maintenance of anaesthesia in each patient with (a) and without Narcotrend-assisted anaesthesia (b). The target level was defined as Narcotrend stages D2–E0. Narcotrend means are calculated from averaging EEG data recorded every 20 s.
