About this study

Official title: High Thoracic Epidural Anesthesia and Postoperative Analgesia With Ropivacaine or Levobupivacaine for Coronary Surgery: A Prospective Randomized Double-Blind Comparison

In High Thoracic Epidural Anesthesia (HTEA) the use of a local anesthetic (LA) with low cardiac toxicity is crucial as myocardial contractility is often already seriously impaired. The aim of this study is to compare the efficacy, doses and side effects of ropivacaine and levobupivacaine in patients submitted to coronary artery bypass graft with HTEA and general anesthesia. The primary end point is the amount of LA drug required to maintain a VAS < 4 when coughing in the first 24 postoperative hours.

Read the detailed description

The use of high thoracic epidural, combined with general anesthesia (HTEA) in patients undergoing cardiac surgery has become increasing popular in recent years. In fact, this technique is potentially beneficial because of the attenuation of the stress response to surgery, the sympathetic tone reduction and the excellent postoperative analgesia.Patients submitted to coronary artery bypass graft will be randomly allocated to receive high epidural block with ropivacaine (R) or levobupivacaine (L), supplemented with sufentanil, during and after surgery. Postoperatively, the rate of epidural infusion will be modified to maintain a VAS score less than 4 in the thoracic area when coughing. VAS, total amount and rate of epidural drug infusion, MAP, total amount and rate of norepinephrine infusion and motor block will be recorded on arrival in the ICU, on awakening and after 4, 8, 12, 24 hours. Additionally, the onset time of the epidural sensory block, the time of awakening and the time on ventilator will be recorded as well as episodes of postoperative nausea and vomiting (PONV) and pruritus.

Ropivacaine, Levobupivacaine

What participants receive

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

  • RopivacaineDrug

    Also called Naropina

    0.5% epidural bolus injection (0.1 mL kg-1) with sufentanil 2.5 µg mL-1 before general anesthesia induction, followed by 0.2% infusion (0.1 mL kg-1 h-1) with sufentanil 1 µg mL-1 throughout surgery; in ICU, 0.1% epidural infusion with sufentanil 1µg mL-1 at 0.1 mL kg-1 h-1 and the rate is modified following this protocol: on awakening (Ramsay 2) VAS on coughing is evaluated: if it is 4 the infusion rate is not changed, if the VAS is ≥ 4 the rate is increased by 2 mL h-1 after giving a 2 mL bolus and VAS is checked again 30 minutes later, if it is ≤ 4 the infusion rate is decreased by 2 mL h-1.

  • LevobupivacaineDrug

    Also called Chirocaina

    0.5% epidural bolus injection (0.1 mL kg-1) with sufentanil 2.5 µg mL-1 before general anesthesia induction, followed by 0.2% infusion (0.1 mL kg-1 h-1) with sufentanil 1 µg mL-1 throughout surgery; in ICU, 0.1% epidural infusion with sufentanil 1µg mL-1 at 0.1 mL kg-1 h-1 and the rate is modified following this protocol: on awakening (Ramsay 2) VAS on coughing is evaluated: if it is 4 the infusion rate is not changed, if the VAS is ≥ 4 the rate is increased by 2 mL h-1 after giving a 2 mL bolus and VAS is checked again 30 minutes later, if it is ≤ 4 the infusion rate is decreased by 2 mL h-1.

What is being measured

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

  1. The amount of local anesthetic drug (mg) required to maintain a visual analog scale score for pain (VAS) < 4 when coughing.

    Measured: the first 24 postoperative hours

Secondary outcomes (1)
  1. - The onset time of a T1-T6 block after the bolus. - the amount of norepinephrine needed to maintain MAP > 70. - differences in motor block. - side effects.

    Measured: The first 24 postoperative hours

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ropivacaine and Levobupivacaine in people with Coronary Artery Bypass and Epidural Anesthesia, run by Centro Cardiologico Monzino at 1 site in Italy.

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 6 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 2 Nov 2007. 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 Italy. 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?

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 amount of local anesthetic drug (mg) required to maintain a visual analog scale score for pain (VAS) < 4 when coughing. (time frame: the first 24 postoperative hours). 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 NCT00552864, 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 2 Nov 2007.
