The dimensionless Narcotrend (NCT) index (MonitorTechnik, Germany, version 4.0), from 100 (awake) to 0, is a new index based on electroencephalogram pattern recognition. Transferring guidelines for titrating the Bispectral Index (BIS, Aspect Medical Systems, USA, version XP) to the NCT index depends on their comparability. We compared the relationship between BIS and NCT values during propofol anaesthesia. ⋯ We found a sufficient correlation between BIS and NCT index, but deviations from the line of identity in some ranges require attention. Therefore, a simple 1:1 transfer from BIS to NCT values is not adequate. Our results might serve as a blueprint for the rational translation of BIS into NCT values.

Thiopental and isoflurane exhibit neuroprotective effects against cerebral ischaemia. Here, we hypothesized that oxygen-glucose deprivation decreases the ATP-dependent phosphorylation process of Focal Adhesion Kinase (pp125FAK, a functionally important non-receptor tyrosine kinase), and that this phenomenon is attenuated by thiopental and isoflurane. ⋯ Phosphorylated pp125FAK content was markedly decreased in hippocampal slices subjected to oxygen-glucose deprivation. Thiopental and isoflurane significantly attenuated this phenomenon, possibly via PKC activation.
