Evidence-based recommendations on 3 electroencephalography (EEG)‑based depth of anaesthesia monitors for assessing a patient’s response to anaesthetic drugs during surgery. The monitors are Bispectral Index (BIS), E‑Entrophy and Narcotrend‑Compact M.

NICE is aware that the Association of Anaesthetists of Great Britain and Ireland (AAGBI) has updated its recommendations for standards of monitoring during anaesthesia and recovery since the publication of diagnostics guidance 6. The standards include recommendations on the use of depth of anaesthesia monitors and can be found at the AAGBI website.

Is this guidance up to date?

We reviewed the evidence in July 2016. We found nothing new that affects the recommendations in this guidance.

Next review: This guidance will be reviewed if there is new evidence that is likely to affect the recommendations.
