Outcomes of an Intraoperative Bispectral Index Monitor

Completed
Conditions
Anesthesia
Interventions
Device: BIS™ Complete 2--Channel Monitor
Registration Number
NCT03052543
Lead Sponsor
Boston Children's Hospital
Brief Summary

This pilot study is being conducted to determine whether the intraoperative presence of a Bispectral Index Monitor (BIS), a non-invasive monitor, affects the perioperative and postoperative indices and outcomes. The BIS monitor is an adhesive sensor that is applied to the forehead to monitor EEG waves. This monitor is not a Standard of Care Monitor, yet in adult and pediatric studies it has been shown to decrease time to emergence, decrease volatile anesthesia requirement, decrease recovery time and in some cases, decrease post-operative morbidity (REFS). The effect on intra-operative and post-operative parameters, when BIS is present but not specifically designated to be used as a monitor to guide anesthesia delivery, has not been specifically examined. This will be the first pediatric study which applies BIS on all patients and randomizes the anesthesiologists to either be or not be privy to seeing the BIS values during intra-operative period.

GroupInterventionDescription
BISvisibleBIS™ Complete 2--Channel MonitorBISvisible group will have the BIS monitor and data available for the anesthesiologist to view. The patient will receive an anesthetic as per the anesthesiologist's particular care plan, unaltered by the study.
BISblindBIS™ Complete 2--Channel MonitorThe BISblind group will have the BIS monitor and data physically hidden from the anesthesiologist. The patient will receive an anesthetic as per the anesthesiologist's particular care plan, unaltered by the study.
