What is being measured

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

  1. total dose and bolus administration of opioid

    After induction of anesthesia, peak velocity of carotid artery blood flow is measured by the pulsed wave Doppler signal obtained from the left common carotid artery. Respirophasic variation of the peak velocity is defined as the difference between the maximum and the minimum values of peak velocity divided by the mean of the two values during one respiratory cycle. Fluid responder is defined as a patient whose stroke volume index is increased ≥15% after volume expansion. The receiver operating characteristic curve analysis to discriminiate fludi responder is performed.

    Measured: an expected average of 48 hrs for requirements of total dose and number of bolus administration of PCA

Secondary outcomes (1)
  1. consequent postoperative nausea and vomiting

    After induction of anesthesia, peak velocity of carotid artery blood flow is measured by the pulsed wave Doppler signal obtained from the left common carotid artery. Respirophasic variation of the peak velocity is defined as the difference between the maximum and the minimum values of peak velocity divided by the mean of the two values during one respiratory cycle. Fluid responder is defined as a patient whose stroke volume index is increased ≥15% after volume expansion. The receiver operating characteristic curve analysis to discriminate fluid responder is performed.

    Measured: an expected average of 48 hrs for assessing of the 11-points verbal numerical rating scales

Questions about this trial

What is this clinical trial studying?

A study testing dexmedetomidine and normal saline in people with PONV, 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 1 inclusion and 10 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 7 Feb 2014. 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. Some participants in this study may receive a placebo. 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?

total dose and bolus administration of opioid (time frame: an expected average of 48 hrs for requirements of total dose and number of bolus administration of PCA). 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 NCT01840254, which also lists 1 linked publication.

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 7 Feb 2014.
