About this study

To find out the effect site concentration of remifentanil for preventing QTc interval prolongation during intubation under propofol-remifentanil anesthesia in elderly patients

Read the detailed description

The increase of Corrected QT (QTc) interval is associated with age. It is known that most inhalation anesthetics or intravenous anesthetics can influence the QTc. In addition, tracheal intubation during induction can stimulates sympathetic activity, which, as a results, prolong the QTc interval. Therefore, the aim of study is to find out the effect site concentration of remifentanil for preventing QTc interval prolongation during intubation under propofol-remifentanil anesthesia in elderly patients.

Questions about this trial

What is this clinical trial studying?

A study testing remifentanil in people with General Surgery With Endotracheal Intubation, run by Severance 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 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 18 Jun 2013. 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?

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?

The effect site concentration for preventing QTc interval prolongation (time frame: 2 min). 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 18 Jun 2013.
