Misinterpretation and Limitations of pEEG Monitoring During Multimodal General Anesthesia

The adequate titration of hypnotic agents can be achieved using processed electroencephalogram (pEEG) monitors. pEEG monitors with a spectrogram, such as bilateral bispectral index (BIS), are useful because they can show different signatures that suggest the effect of a given drug on brain activity. Multimodal general anesthesia is based on a combination of hypnotic and antinociceptive agents. We report a case of awareness in a patient monitored...
