Depth of anaesthesia monitors – Bispectral Index (BIS), E-Entropy and Narcotrend-Compact M

7.1 The Committee encourages further research as described in section 6.13 but has made no specific research recommendations. This is because, although there is uncertainty about many aspects of depth of anaesthesia monitoring (as described in section 6), the Committee considered that the current evidence base suggests depth of anaesthesia monitoring offers clinical benefits. Given the many complications in undertaking research in this area of anaesthesia, the Committee considered that the current uncertainty in the evidence base does not justify a potentially long delay in the uptake of what is likely to be a beneficial technology to the NHS and, particularly, to patients.
