About this study

Obstructive sleep apnea is a common disease, associated with cardiovascular disease, cerebrovascular disease, and many other medical conditions. Therefore the precise diagnosis and treatment are important. With drug-induced sleep endoscopy (DISE), the three-dimensional evaluation of upper airway and airway obstruction could be possible. The problem of the DISE is that there is the difference between a sedative-induced sleep and normal sleep. Moreover there were no standard sedation protocol of DISE. Propofol has short half-life, about 3 minutes, so the patients could recover quickly from it. In recent years, using target controlled infusion(TCI) of propofol, the effective effect-site concentration for DISE could be reached easily with hemodynamic stability and minimal toxic effect. In a previous pilot study, the endoscopy for the diagnosis of sleep apnea could be done successfully with propofol TCI. However there were some desaturation events, although the EEG showed that the patient was not in deep sleep enough. Therefore we thought that not only further study of propofol for DISE but also the study of other drugs for DISE will be needed to overcome this limitation. Dexmedetomidine, the selective α2-adrenoreceptor agonist, has analgesic effect and almost no respiratory depression, therefore it could be a good alternative drug for DISE. The purpose of this study is designing the appropriate sedation protocol for DISE using propofol or dexmedetomidine, and enabling the safer and more accurate DISE.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PropofolDrug

    Propofol TCI: effect-site concentration(Ce): Ce was titrated to 1.0 μg/ml and increased by 0.2 μg/ml every five minutes

  • propofol-remifentanilDrug

    Propofol TCI: effect-site concentration(Ce): Ce was titrated to 1.0 μg/ml and increased by 0.2 μg/ml every five minutes Remifentanil TCI: effect-site concentration(Ce): Ce was titrated to 1.5 μg/ml

  • Dexmedetomidine-remifentanilDrug

    Dexmedetomidine infusion: After the loading dose (1 mcg/kg for 10 minutes), the continuous infusion was done (0.2 mcg/kg/hr) and the infusion rate was increased by 0.2 mcg/kg/hr every five minutes (maximum infusion rate: 1.4 mcg/kg/hr) Remifentanil TCI: effect-site concentration(Ce): Ce was titrated to 1.5 μg/ml

What is being measured

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

  1. Desaturation rate

    SpO2 < 90% (checked by pulse oximetry)

    Measured: Baseline / 5 min after remifentanil TCI start / 5 min after propofol TCI start or 10 min after dexmedetomidine loading start / every 5 min until surgeon can do endoscopy successfully / immediately after endoscopy

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Propofol, propofol-remifentanil and Dexmedetomidine-remifentanil in people with Obstructive Sleep Apnea, run by Yonsei University 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 3 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 17 Aug 2016. 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.

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?

Desaturation rate (time frame: Baseline / 5 min after remifentanil TCI start / 5 min after propofol TCI start or 10 min after dexmedetomidine loading start / every 5 min until surgeon can do endoscopy successfully / immediately after endoscopy). 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 17 Aug 2016.
