Outcomes of an Intraoperative Bispectral Index Monitor

October 13, 2020 updated by: Keira Mason, Boston Children's Hospital

A Pilot Study to Determine the Outcomes of an Intraoperative Bispectral Index Monitor

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
BISblind
The 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.
Device: BIS™ Complete 2--Channel Monitor
monitor depth of anesthesia
BISvisible
BISvisible 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.
Device: BIS™ Complete 2--Channel Monitor
monitor depth of anesthesia

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
BIS values
Time Frame: intraoperative period
Compare the BIS values in the BISblind and BISvisible groups
intraoperative period

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Amount of intravenous anesthetic medications administered
Time Frame: intraoperative period
Compare the amount of intravenous anesthetic medications administered between the BISblind and BISvisible groups
intraoperative period
