“…BIS is equal to 100 when the patient is fully awake and 0 when an isoelectric electroencephalogram is observed. It has been reported that BIS is useful to evaluate the sedation depth during digestive endoscopy or treatment [10] .…”

AIM:To assess the usefulness of bispectral index (BIS) monitoring in order to carry out endoscopic submucosal dissection (ESD) safely and with patients' satisfaction. METHODS:Three hundred sixty-six patients with an early-stage neoplasm of the digestive tract were enrolled. The BIS monitor (A-1050: Aspect medical systems/NIHON KOHDEN, Tokyo, Japan) was used. The appropriate sedative condition was set at 55 to 75 BIS levels (BIS value) during the endoscopic procedures. RESULTS:Among 366 cases, 13 were accompanied by adverse events during and/or after ESD. All episodes occurred in cases with BIS value between 56 and 65. Hypotension was observed in four cases, and bradycardia in six. Respiratory distress was observed in two cases with chronic pulmonary obstructive disease. All patients with adverse events were able to leave the hospital without extension of the hospitalization.CONCLUSION: BIS monitoring is useful to safely perform ESD. A BIS value of 70 to 75 is suitable for ESD.

“…The BIS scale varies from 0 to 100 (0 no cortical activity or coma; 40-60 unconscious; 70-90 varying levels of conscious sedation; 100 fully awake). Unfortunately, there is patient to patient variability in the score, which limits it use in the endoscopy suite [3]. An exciting development for future monitoring may be automated responsiveness monitoring (ARM) [4].…”

“…For obtaining general anesthesia routinely, BIS levels between 40 and 60 were necessary. In a preliminary study of 50 patients who underwent several endoscopic procedures under sedation with diazepam and meperidine, a significant temporal correlation of the BIS level and the clinical assessment of patient consciousness was described [3]. Another pilot study described bispectral monitoring as part of a closed monitoring cycle for the continuous infusion of propofol in 16 patients sedated for colonoscopy [4].…”

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.
