About this study

Official title: Comparative Population Pharmacodynamic Modeling for Sevoflurane Effects Using Anesthetic Depth Monitoring for Sedation (ADMS) and Bispectral Index System (BIS)

The investigators want to compare the performance of anesthetic depth monitoring for sedation (ADMS) to the bispectral index (BIS) as electroencephalographic measures of sevoflurane effect using two combined sigmoidal Emax models via population pharmacodynamic approach.

Read the detailed description

Intraoperative awareness under general anesthesia is rare, but it may cause serious psychological sequelae. Anesthetic depth monitoring system based on electroencephalography(EEG) or evoked potential are broadly used methods. Bispectral index (BIS) monitor is most popular anesthetic depth monitoring system. Anesthetic depth monitoring for sedation (ADMS) is developed in Korea as an electroencephalographic monitor for measuring the depth of anesthesia. The investigators want to compare the performance of ADMS to the bispectral index (BIS) as electroencephalographic measures of sevoflurane effect using two combined sigmoidal Emax models via population pharmacodynamic approach.

What is being measured

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

  1. Bispectral Index (BIS)

    captured BIS data (0~100) from the BIS system after induction of general anesthesia, sevoflurane concentrations will be progressively increased and then decreased over 70 min.

    Measured: Data capture will be started 45 minutes after induction of general anesthesia for 70 minutes

  2. Anesthetic depth monitoring for sedation (ADMS)

    captured ADMS data (0~100) from the ADMS system after induction of general anesthesia, sevoflurane concentrations will be progressively increased and then decreased over 70 min.

    Measured: Data capture will be started 45 minutes after induction of general anesthesia for 70 minutes

Secondary outcomes (1)
  1. Adverse events

    Observe all adverse events both groups

    Measured: visit patients 24 hours after operation.

Questions about this trial

What is this clinical trial studying?

A study testing BIS and ADMS in people with Anesthesia, run by Chonnam National University Hospital at 1 site in South Korea.

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 1 inclusion and 4 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: status not confirmed, as of the sponsor's last update on 3 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. 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.

Are results available for this study?

Results are not available in the source record.

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

Contact Tae-hee Pyeon, MD (+82-10-2705-9901, skybluevus@naver.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Bispectral Index (BIS) (time frame: Data capture will be started 45 minutes after induction of general anesthesia for 70 minutes). The study lists 2 primary outcomes in all. 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 NCT03069456, which also lists 3 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 3 Mar 2017.
