Extended monitoring of the sedated patient: bispectral index, Narcotrend and automated responsiveness monitor.
It has been demonstrated that a processed EEG derivative may reflect the patient's level of consciousness during endoscopic sedation. However, to date a clinical benefit of EEG monitoring with respect to relevant safety parameters in routine gastrointestinal endoscopy has not been demonstrated. During long-lasting procedures (e.g. ERCP, ESD) a propofol-sparing effect has been shown, but a benefit regarding patient safety could not be documented. The use of an automated responsiveness monitor may help to achieve and to maintain the level of conscious sedation with propofol, but its precise role in endoscopic sedation is undefined.
