Outcome Measures

Primary Outcomes (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.

    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)

  • A change in systolic function from the baseline value.

    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.

Study Arms (2)

Remifentanil 2 ng/mL

EXPERIMENTAL

Following 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.

Drug: Remifentanil 2 MGDiagnostic Test: Echocardiographic evaluation

Baseline

EXPERIMENTAL

Baseline transthoracic echocardiographic examination will be performed in the spontaneously breathing patients right before the surgical procedure and study drug infusion begins.

Diagnostic Test: Echocardiographic evaluation

Interventions

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.

Also known as: Ultiva 2 mg., Rentanil 2 mg., Opiva 2 mg.

Model Details: 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.
