EEG/Bispectral Index (BIS) Monitoring - Neuromuscular Blockade



 • Use EEG/BIS monitor to ensure sedation depth is adequate

 • The principle is that EEG monitoring provides an quasi-empiric measure of anesthesia depth, which is used to titrate sedation during NMB. Theoretically this prevents both oversedation & undersedation.

 • Bispectral index is an algorithmic technique to combine multiple EEG parameters, providing a single

numeric output

 • There is no evidence that BIS monitoring reduces awareness of NMB, nor that it simplifies sedations
