Optimization of the Anesthetic Regimen Using the SmartPilot® System and Influence on Different Outcome Parameters - a Pilot Study.

June 27, 2019 updated by: Claudia Spies

Optimization of the Anesthetic Regimen Using the SmartPilot® System and Influence on Different Outcome Parameters - a Pilot Study. A Single- Center Prospective Randomized Controlled Pilot Study.

This study investigates whether general anesthesia using a Pharmacokinetic/Pharmacodynamic (PK/PD) -model-based index indicating the compound effect of different anesthetics leads to optimized outcome compared to manually controlled clinical anesthesia and computerized Electroencephalogram (EEG).

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

18 years to 90 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

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.
SmartPilot® system
50 patients scheduled for elective surgery (general/abdominal surgery; traumatological/orthopedic surgery, gynecology, urology) in general anesthesia using the SmartPilot® system

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
Postoperative delirium
Time Frame: In the 8-day postoperative sample period
Nursing Delirium Csreening Scale (Nu-DESC), Confusion Assessment Method for the Intensive Care Unit (CAM-ICU), Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-R), International Classification of Diseases (ICD-10)
In the 8-day postoperative sample period
Postoperative cognitive deficit
Time Frame: In the 8-day postoperative sample period
Test Battery: Verbal Learning Test, Stroop Colour Word Test, Letter Digit Substitution Test, Concept Shifting Test
In the 8-day postoperative sample 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
Time Frame
Wake-up time
Time Frame: In the 8-day postoperative sample period
In the 8-day postoperative sample period
Duration of treatment in the recovery room
Time Frame: In the 8-day postoperative sample period
In the 8-day postoperative sample period

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
November 12, 2013

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
