About this study

Official title: Comparison Between Levobupivacaine 0.25% and Levobupivacaine With Dexmedetomidine in Ultrasound Guided Modified Pectoral Nerve Block, a Double Blind Randomised Controlled Trial.

A double blind prospective randomized controlled trial in which the effect of single shot levobupivacaine 0,25% will be compared with the effect of levobupivacaine 0.25% in association with dexmedetomidine when performing an ultrasound guided modified pectoral nerve block , in patients undergoing a mastectomy with axillar procedure.

The difference in effect will be evaluated by monitoring the postoperative morphine consumption in both groups .

The hypothesis is that there is a significant decrease in morphine consumption during the first 24h postoperatively due to association of dexmedetomidine to the local anesthetic compared to the local anesthetic alone when performing a ultrasound guided modified pectoral nerve block. The morphine consumption will be the primary outcome parameter.

Read the detailed description

Women (18+, American Society of Anesthesiologists 1,2,3) undergoing a mastectomy with axillar procedure will be randomised and receive a ultrasound guided modified pectoral nerve block, if participants meet in- and exclusion criteria and provide written informed consent.

Using a two needle approach, ten milliliters of local anesthetic is injected under ultrasound guidance between the major and minor pectoral muscle and twenty milliliters between the minor pectoral and the serratus anterior muscle, on the side to be operated.

Participants receive intravenous Patient Controlled Analgesia with morphine and dehydrobenzperidol (1mg/ml morphine, 50µg dehydrobenzperidol/ml).

Furthermore every participant in the trial will receive ketorolac 0.5mg/kg three times a day and paracetamol four times 1g per day.

When the analgesia using the intravenous Patient Controlled Analgesia regime isn't sufficient, the anesthesiologist will titrate with morphine until pain free using a protocol (a bolus of 2mg morphine IV every ten minutes until pain free).

What is being measured

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

  1. Total postoperative opioid (morphine) consumption

    Milligrams of morphine used by the patient registrated by patient controlled intravenous analgesia delivery device (PCIA) during 24 hours after surgery

    Measured: 24 hours post procedure

Secondary outcomes (3)
  1. Onset of postoperative pain

    Time between end of general anesthesia and a patients first demand of morphine registrated by PCIA.

    Measured: 24 hours post procedure

  2. Number of boluses morphine the patient asked for in the first 24 hours postoperative

    Amount of times the patient pushed the PCIA button even during lockout time period

    Measured: 24 hours post procedure

  3. Number of effectively delivered morphine boluses in the first 24 hours postoperatively

    Amount of times the patient pushed the PCIA button and morphine is delivered.

    Measured: 24 hours post procedure

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Levobupivacaine and Levobupivacaine + Dexmedetomidine in people with Breast Cancer and Mastectomy, Modified Radical, run by University Hospital, Antwerp at 1 site in Belgium.

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 4 inclusion and 11 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: stopped early, as of the sponsor's last update on 20 Sep 2019. 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 Belgium. 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 was stopped early (reason given: The surgical approach has changed.). Results are not available in the source record.

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?

Total postoperative opioid (morphine) consumption (time frame: 24 hours post procedure). 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 20 Sep 2019.
