About this study

Official title: Target-controlled Infusion of Propofol and Remifentanil During General Anaesthesia Guided by the Index Bispectral: Comparison Between Manual Perfusion and Automated Perfusion

To compare manual administration of propofol and remifentanil and dual closed-loop using bispectral index as the control variable during anesthesia

Read the detailed description

The Bispectral Index (BIS) is an electroencephalogram-derived measure of anesthetic depth. A closed-loop anesthesia system can be built using BIS as the control variable, a proportional-integral-differential control algorithm, and a propofol target-controlled infusion system as the control actuator. Recent studies have shown that such system is able to provide clinically adequate anesthesia. We hypothesized that BIS can also indicate the adequacy of analgesia and therefore built a combined closed-loop anesthesia system using BIS as the control variable, two proportional-integral-differential control algorithms, a propofol and a remifentanil target-controlled infusion systems as the control actuators. In preparation for a large multi-center control trial, we propose a prospective randomized study to evaluate the effectiveness of such a closed-loop anesthesia system. Two groups of patients are compared: one in which propofol and remifentanil are administered by the anesthesiologist using target-controlled infusion systems, and one in which propofol and remifentanil are administered automatically by the combined closed-loop anesthesia system. In both groups, the goal is to maintain BIS between 40 and 60, the recommended range during anesthesia by the manufacturer. We expect the combined closed-loop anesthesia system group to do similar or better.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Global score (calculated parameter which depicts the performance of the system, i.e. its capacity to maintain BIS in the desired range)

Secondary outcomes (6)
  1. consumption of propofol and remifentanil during the induction and the maintenance of the anaesthesia

  2. number of modifications of target of propofol and remifentanil

  3. number of episodes of hemodynamic anomalies having required a treatment

  4. intraoperative volume loading and transfusion

  5. extubation time, explicit memorisation

  6. dysfunctions of each system

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Closed-loop anesthesia system in people with Anesthesia, General, run by Hopital Foch at 6 sites in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Sep 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Global score (calculated parameter which depicts the performance of the system, i.e. its capacity to maintain BIS in the desired range). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00392158, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Sep 2016.
