About this study

Official title: Randomized Controlled Trial Investigating Use of Liposomal Bupivacaine in Bariatric Surgery

The aim of this study is to perform a randomized controlled trial for patients undergoing bariatric surgery, comparing the need for opiates with and without administration of a transversus abdominis plane (TAP) block using the long acting local anesthetic, liposomal bupivacaine (Exparel®). From this study, the investigators will assess whether use of long acting local anesthetic can reduce the need for opiates in the bariatric population.

Read the detailed description

A prospective randomized controlled trial investigating the use of long acting local anesthetic for transversus abdominis block in patients undergoing bariatric surgery at Montefiore Medical Center. Patients will be randomized to either receive an intraoperative TAP block with LB, an intraoperative TAP block with RB, or no TAP block. All participants will receive standard post-operative analgesia regimen. Pain scores will be recorded by the nursing staff as reported by the patients for 24-36 hours post surgery. Patients will be monitored for secondary post-operative complications up to the 2-week mark following intervention.

Study groupRoleWhat they receive
Liposomal Bupivacaine TAP blockExperimentalPatients will be randomized to receive an intraoperative transverse abdominis peritoneal (TAP) block with liposomal bupivacaine (LB). The solution used to perform the TAP block with LB will comprise of 20mL of liposomal bupivacaine solution, 30mL of 0.25% bupivacaine, and 100mL of normal saline.

What is being measured

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

  1. Fentanyl PCA mcg

    Fentanyl PCA (patient controlled analgesia) total microgram usage.

    Measured: 24 hours post surgery.

  2. Total Fentanyl Usage

    Total fentanyl usage in micrograms, including both PCA and IV push administered medication.

    Measured: During hospitalization, up to 7 days.

Secondary outcomes (6)
  1. Acetaminophen Usage

    Total amount of acetaminophen used for analgesia.

    Measured: During hospitalization, up t 7 days.

  2. NSAID Usage

    Total amount of NSAID (ketorolac) use for analgesia.

    Measured: During hospitalization, up to 7 days.

  3. Pain Score

    Patient reported composite measure pain score, with a total range of 0 to 10, with 0 being the absence of pain, 1 being the least amount of pain and 10 being the highest amount of pain.

    Measured: 24 hours post surgery.

  4. Length of Stay

    Hours of hospitalization post-surgery

    Measured: Assessed every 24 hours post surgery, up to 168 hour post-surgery.

  5. Nausea

    Number of participants with presence or absence of nausea reported and recorded by the nurse.

    Measured: 24 hours post surgery.

  6. Time to Ambulation

    Measured: Assessed every 24 hours post surgery, up to 168 hour post-surgery.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Liposomal Bupivacaine TAP block and Bupivacaine TAP block in people with Bariatric Surgery Analgesia, run by Montefiore Medical Center at 1 site in United States.

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 10 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 4 Nov 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 United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 4 Nov 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Fentanyl PCA mcg (time frame: 24 hours post surgery.). The study lists 2 primary outcomes in all. 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 4 Nov 2019.
