Comparison of Two Electroencephalograms (EEG) Monitors in Patients Undergoing General Anesthesia With Sevoflurane
A study testing qCON monitor in people with General Anesthesia, run by Hopital Foch at 1 site in France.
Trial summary
Quantium Medical Company has an ElectoEcenphalograph-based (EEG-based) algorithm with two outputs: qCON for unconsciousness and qNOX for anti-nociception. qCON, is designed to provide information about the depth of the hypnotic state, similar to that provided by the BIS™. Read more about this study

Questions about this trial
What is this clinical trial studying?
A study testing qCON monitor in people with General Anesthesia, run by Hopital Foch at 1 site 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 5 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: finished, as of the sponsor's last update on 24 Aug 2018. 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 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.
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?
qCON monitoring during maintenance of anesthesia (time frame: up to 10 hours). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 24 Aug 2018; AzTrials last refreshed its copy on 6 Nov 2026.
