About this study

Official title: The Comparison of Antiarrhythmic and Myocardial Protective Effect Between Lidocaine, Dexmedetomidine, and Their Combined Infusion in Subjects Undergoing Coronary Artery Bypass Graft

The aim of the present study is to compare the antiarrhythmic and myocardial protective effect between lidocaine, dexmedetomidine, and their combined infusion in subjects undergoing coronary artery bypass graft.

Read the detailed description

Lidocaine has been reported to have an antiarrhythmic and myocardial protective effect. A previous study has reported that low-dose lidocaine infusion can decrease the incidence of ventricular fibrillation and tachycardia during the first 24 hours after coronary artery bypass graft (CABG). A recent study also reported that the lidocaine infusion during CABG could decrease the myocardial injury by measuring the CK-MB and Troponin-I blood level.

Dexmedetomidine is an alpha-2 agonist and reduces the sympathetic tone and neuroendocrine stress response. Dexmedetomidine was reported to have a cardioprotective effect by a previous animal study. However, there was no clinical study evaluating the cardioprotective effect of dexmedetomidine.

Therefore, we are trying to evaluate and compare the antiarrhythmic and myocardial protective effect between lidocaine, dexmedetomidine, and their combined infusion in subjects undergoing coronary artery bypass graft.

Questions about this trial

What is this clinical trial studying?

A study testing Lidocaine infusion and Dexmedetomidine infusion in people with Unstable Angina and Coronary Artery Bypass Graft, run by Samsung Medical Center 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 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 27 Oct 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. 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?

Myocardial injury marker (time frame: postoperative ICU day 1). The study lists 3 primary outcomes in all. 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 27 Oct 2014.
