About this study

Official title: Comparative Study on Development of Paradoxical Excitement Response During Sedation Using Dexmedetomidine or Propofol in Hazardous Alcohol Drinkers

  1. Adequate sedation with classical sedative agents, propofol
  2. Sedation with propofol may induce paradoxical excitement response in heavy alcohol drinkers
  3. Dexmedetomidine, α2 receptor agonist, may provide adequate sedation in heavy alcohol drinkers
Read the detailed description
  1. Adequate sedation during surgery provide anxiolysis and comfort to patient. Insufficient sedation can't provide comfort to patient during surgery, otherwise excessive sedation can cause variable complications like respiratory depression or delayed awakening.
  2. Dexmedetomidine is a centrally acting α2 receptor agonist that is increasingly being used as a sedative for MAC and intensive care with mechanical ventilated patients because of its analgesic properties, "cooperative sedation," and lack of respiratory depression.
  3. Because of the different site of action between dexmedetomidine and propofol, we assumed that paradoxical excitement responses which appeared in heavy alcohol drinkers in midazolam or propofol-induced sedation might be less observed in dexmedetomidine-induced sedation.

What is being measured

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

  1. Paradoxical excitement response

    Paradoxical excitement responses (verbal/movement) 0, none : no excitement response

    1. mild : increased talkativeness, irrational talking / brief spontaneous movement with position remaining
    2. moderate : restlessness, loss of cooperation, spontaneous movements requiring repositioning with no need of restraint
    3. severe : agitation and spontaneous movements with a need to restrain the patient

    Measured: Every 5 minutes up to 120minutes after drug infusion

Secondary outcomes (2)
  1. OAA/S

    Observer''s Assessment of Alertness/Sedation Scale (OAA/S)

    1. :Does not respond to mild prodding or shaking
    2. :Responds only after mild prodding or shaking
    3. :Responds only after name is spoken loudly and/or repeatedly
    4. :Lethargic response to name spoken in normal tone
    5. :Responds readily to name spoken in normal tone

    Goal to sedation : 3

    Measured: Every 5minutes up to 120minutes after drug infusion

  2. Vital signs

    Check blood pressure, heart rate, oxygen saturation, bispectral index

    Measured: During operation

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 5 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 14 Mar 2019. 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?

Results are not available in the source record.

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

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Paradoxical excitement response (time frame: Every 5 minutes up to 120minutes after drug infusion). 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 NCT02197403, which also lists 4 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 14 Mar 2019.
