NICE GUIDELINES RECOMMEND BIS™ MONITORING
"BIS™ monitoring is recommended as an option for all patients receiving total intravenous anesthetic (TIVA). BIS™ technology is also cost effective in this patient population due to the inability to measure end-tidal anesthetic concentration."([FOOTNOTE=National Institute for Health and Clinical Excellence. Depth of anaesthesia monitors (E-Entropy, BIS™ and Narcotrend) (DG6). November 2012. Available at: http://guidance.nice.org.uk/DG6.],[ANCHOR=],[LINK=])
