About this study

Official title: Effects of Remifentanil on Diastolic and Systolic Function in Patients With Diastolic Dysfunction

In this study ASA 1, 2 individuals with grade 1 or 2 diastolic dysfunction will be recruited to assess the effects of Remifentanil infusion on left ventricular function evaluated with transthoracic echocardiagraphy.

Read the detailed description

Our aim in this study is to evaluate the effects of Remifentanil infusion on left ventricular function evaluated with transthoracic echocardiagraphy on ASA 1, 2 individuals with grade 1 or 2 diastolic dysfunction. Methods: 30 ASA 1-2 individuals with grade 1 or 2 diastolic dysfunction whose left ventricular ejection fraction is above 50% will be recruited. The patients will be selected among the ones who planned to undergo elective surgery either under general or regional anesthesia.

Patients with atrial fibrillation, atrioventricular block, severe heart valve disease, tachyarrhythmia-bradyarrhythmia, left ventricular ejection fraction < 50% and regional contraction anomaly, patients with liver, renal dysfunction, patients with lung disease, acute coronary syndrome, body mass index >30 kg/m2, no oral intake for solid food more than 8 hours will be excluded from the study.

Baseline echocardiographic examination will be performed in the spontaneously breathing subjects right before the surgical procedure and study drug begins. Then remifentanil infusion will be started at a rate to reach target plasma level of 2 ng/mL. A target Controlled Infusion pump will be used to infuse the study drug. Once the target drug concentration is reached, the final echocardiographic examination will be performed.

After recording the baseline heart rate, respiratory rate, noninvasive blood pressure, pulse oximeter, sedation level, the same parameters will be recorded every 5 minutes during the remifentanil infusion period. Once the final echocardiographic evaluation is performed abovementioned parameters will be recorded for the last time.

Statistical analysis: The sample size calculation is made according to an increase or decrease in E/e' (alpha <0,05; beta= 0,8).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Remifentanil 2 MGDrug

    Also called Ultiva 2 mg., Rentanil 2 mg., Opiva 2 mg.

    Once the participants transferred to operating room, electrocardiography, noninvasive blood pressure, pulse oximetry, and respiratory rate will be recorded. An increase or decrease from the baseline value of 30% in mean arterial pressure will be treated with iv boluses of (5 mg) ephedrine or glyceryl trinitrate (25 micg). All the participants will undergo a baseline transthoracic echocardiographic evaluation to assess the systolic and diastolic function of the left ventricle before the infusion of the study drug. Then the patients will be given oxygen by a face mask at a rate of 5-6 L/min, and Remifentanil infusion will be started using a target controlled infusion pump to reach a target plasma concentration of 2 ng/mL. Once the target concentration is reached, second echocardiographic evaluation to assess the systolic and diastolic function will be performed. Potential side effects of Remifentanil will be monitored.

  • Echocardiographic evaluationDiagnostic test

    Transthoracic echocardiographic examination will be performed in the spontaneously breathing patients right before the surgical procedure.

Remifentanil 2 ng/mLExperimentalFollowing baseline echocardiographic evaluation, Remifentanil (ultiva at a concentration of 20 micg/ml) infusion will be started at a rate to reach a target plasma level of 2 ng/mL. A target Controlled Infusion pump will be used to infuse the study drug. Once the target drug concentration is reached (which is expected to reach around 10-15 minutes), the final echocardiographic examination will be performed.

What is being measured

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

  1. A change in diastolic function from the baseline value.

    A change from the baseline diastolic function evaluated with echocardiography which is measured as soon as the patient arrives at the operating room when compared to diastolic function measured after reaching the target (2ng/mL) plasma concentration of remifentanil.

    Measured: Following baseline measurement, the second measurement will be performed as soon as the 2 ng/mL target plasma level of remifentanil is reached. This will probably take 15 to 20 minutes for each patient until the end of the 6 month long study period.]

Secondary outcomes (1)
  1. A change in systolic function from the baseline value.

    A change from the baseline systolic function evaluated with echocardiography which is measured as soon as the patient arrives at the operating room when compared to systolic function measured after reaching the target (2ng/mL) plasma concentration of remifentanil.

    Measured: Following baseline measurement, the second measurement will be performed as soon as the 2 ng/mL target plasma level of remifentanil is reached. This will probably take 10 to 15 minutes for each patient until the end of the 6 month long study period.

Model description
Baseline echocardiographic examination will be performed to evaluate the systolic and diastolic function of the left ventricle in the spontaneously breathing subjects right before anesthesia and study drug infusion begins. Then the same participants will be given remifentanil (ultiva at a concentration of 20 micg/ml) at a rate to reach a target plasma level of 2 ng/mL by means of a target controlled Infusion pump. Once the target drug concentration is reached (which is expected to take around 10-15 minutes), the final echocardiographic examination will be performed to assess systolic and diastolic function again.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Remifentanil 2 MG and Echocardiographic evaluation in people with Diastolic Dysfunction, run by Yeditepe University at 1 site in Turkey (Türkiye).

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 1 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 19 May 2020. 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 Turkey (Türkiye). 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?

Contact Özge Köner, Professor (00905324145859, ozgekoner@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

A change in diastolic function from the baseline value. (time frame: Following baseline measurement, the second measurement will be performed as soon as the 2 ng/mL target plasma level of remifentanil is reached. This will probably take 15 to 20 minutes for each patient until the end of the 6 month long study period.]). 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 NCT04117009, which also lists 2 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 19 May 2020.
