February 7, 2017 updated by: Gaurav Arora, University of Pittsburgh

Dexmedetomidine Versus Adenosine: Electrophysiologic Effects and Therapeutic Use for Terminating Supraventricular Tachycardia

The purpose of this study is to evaluate the efficacy and safety of dexmedetomidine in the acute termination of Supraventricular Tachycardia (SVT).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

In 2006 the investigator found that dexmedetomidine, an alpha-2 adrenergic agonist with primarily sedative properties, possesses additional anti-arrhythmic properties. So far the investigator has found that dexmedetomidine has the ability to prevent or terminate arrhythmias like atrial ectopic tachycardia (85% success) and junctional ectopic tachycardia (75% success). The most dramatic effect however was observed in the acute termination of reentrant SVT with a success rate of > 96%. More importantly we found that dexmedetomidine terminates SVT without causing any sinus pause or asystole (frequently seen with adenosine) and thus avoiding the feeling of "impending doom". In this study adenosine is being compared head to head with dexmedetomidine in a cross over study, for both safety and efficacy when given for the termination of SVT in the electrophysiology (EP) lab. Additional EP parameters will be measured to elucidate the exact site of dexmedetomidine's mechanism of action.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

5 years to 30 years (ADULT, CHILD)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Drug: Dexmedetomidine
Dexmedetomidine 2 mcg/kg, Intravenous push

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Termination of SVT
Time Frame: Within 3 minutes
Number of participants with SVT Termination within 3 minutes of medication administration
Within 3 minutes

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Sinus Pause >2.5 Sec After Termination of SVT
Time Frame: 1 minute
Evaluation of the number of participants with sinus pause > 2.5 sec, after dexmedetomidine vs. adenosine induced SVT termination
1 minute
Number of Participants With Tachyarrhythmias After Medication Administration
Time Frame: 10 minutes
Number of participants with tachyarrhythmias, including Ventricular (Ventricular Tachycardia & Fibrillation)and supraventricular (Atrial Flutter & Fibrillation) after dexmedetomidine vs. adenosine administration
10 minutes
Number of Participants With Hypotension by Non-invasive Cuff in First 10 Minutes After Medication Administration
Time Frame: 10 minutes
Blood pressure changes after dexmedetomidine vs. adenosine. Blood pressure measured by non-invasive cuff prior to medication administration, and then at 1 min, 3 min, 5 min after medication administration. Number of participants with a significant drop in blood pressure (mmHg) compared to baseline would be counted for hypotension.
