About this study

Official title: Transversus Abdominis Plane Blocks in Patients Scheduled for an Abdominoplasty. A Prospective, Randomized, Double Blind, Comparison Between the Posterior Approach and Placebo.

Comparing morphine consumption and recovery with two different TAP block techniques after abdominoplasty.

Read the detailed description

TAP blocks have the potential to become an important part of multi-modal analgesia after abdominal surgery (1,2). Originally Dr J McDonnell described a blind double pop technique, trough the triangle of Petit, with up to 48 hours of analgesia (3,4). Dr P Hebbard described an ultrasound based technique with a subcostal (for supra-umbilical analgesia) and an axillary mid-line injection (for sub-umbilical analgesia) in the TAP, with reported analgesia for up to 8 hours (5,6). Recently Dr J McDonnell presented data showing para vertebral spread (up to L5) of the (high dose, low concentration) local anaesthetic explaining the prolonged analgesic effect (7,8). In 2007 Dr Blanco described an ultrasound guided technique for the posterior infiltration as performed by McDonnell (9). Our limited observational comparison between both block techniques confirms this difference. We decided to compare both techniques (the ultrasound guided single shot subcostal injection, the aTAP-group (Hebbard is from Australia) and the ultrasound guided posterior injection, the iTAP-group (McDonnell is from Ireland). We will use the same volume and concentration of local anesthetic and we will asses their analgesic efficacy and improvement in quality of recovery.

A Phase 4 study testing Ropivacaine 0.25%, 0.5 ml/kg in people with Post Operative Pain, run by Clinique Saint-Jean, Bruxelles 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 3 inclusion and 3 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 27 Apr 2011. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Arnaud G Bosteels, MD (02 221 97 62 ext. 0032, Abosteels@clstjean.be), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Morphine consumption (time frame: 48 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 NCT01278264, which also lists 9 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 27 Apr 2011.
