About this study

Official title: Prospective Randomized Trial of Liposomal Versus Plain Bupivacaine in Minimally Invasive General Surgery Procedures

Aim: To compare the postoperative outcomes after surgical infiltration with plain bupivacaine compared to liposomal bupivacaine in patients undergoing elective, minimally invasive, general surgery procedures. To the investigators knowledge, there are no head-to-head, prospective, randomized, controlled trials of plain bupivacaine versus liposomal bupivacaine to evaluate postoperative pain and return of function.

Read the detailed description

The investigators current standard has been to use liposomal bupivacaine routinely for surgical infiltration which was a change from the historical practice of infiltration with lidocaine/bupivacaine, plain bupivacaine or no local anesthetic at all. The change was made due to the perceived benefits in analgesia past the 12-24 hours that plain bupivacaine was effective. It is not clear, however, that there are statistically significant benefits in terms of reduced narcotic use and length of hospital stay and improved pain control and return of function post-operatively.

Primary outcomes: The investigators will then measure narcotic use post-operatively as calculated by combining measures of patient-controlled analgesia (PCA) use for first 24 hours added to in-patient oral narcotic use (by referencing the electronic medical record (EMR)) as well as out-patient oral narcotic use as reported by patients. Subjective pain levels and pain interference scale and physical functioning scale will be evaluated pre-operatively and post-operatively with use of the Pain Assessment Screening Tool and Outcomes Registry (PASTOR) developed by the Defense and Veterans Center for Integrative Pain Management (DVCIPM) as a measure of perioperative pain and function.

What participants receive

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

  • liposomal bupivicaineDrug

    Also called Exparel

    1. The intervention that is being tested and who will perform the procedures; Two general surgeons will perform the procedure with either liposomal or plain bupivacaine.
    2. The treatment procedures or regimens; The treatment procedure is direct, surgical site infiltration with either liposomal or plain bupivacaine.
    3. Dosage level and justification; Liposomal Bupivacaine: 266 mg/20 mL liposomal bupivacaine diluted to 30 mL Plain Bupivacaine: 30 mL of 0.5% plain bupivacaine

What is being measured

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

  1. Total post operative narcotic use in morphine equivalents.

    To be measured by combining measures of Patient-Controlled Analgesia pump use for the first 24 hours added to in-patient oral narcotic use (by referencing the electronic medical record (EMR) and out-patient oral narcotic use as reported by patients.

    Measured: Up to fourteen days.

Secondary outcomes (4)
  1. Length of hospital stay post operative procedure.

    Participants post operative procedure length of stay will be determined from the electronic medical record.

    Measured: up to fourteen days.

  2. Pain level pre and post operative procedure.

    Baseline pain level will be gathered pre operative procedure and post operative procedure day one, seven, and fourteen through the 0 to 10 pain scale with 0 being "No Pain", 5 being "Moderate Pain", and 10 being "Worse Possible Pain".

    Measured: Up to fourteen days.

  3. Post operative procedure physical functioning level.

    Data is gathered on POP day one, seven and fourteen through the Physical Functioning Scale (PFS), which is scored from 0 to 100 with a higher scores indicating better physical function.

    Measured: Up to fourteen days.

  4. Number of post operative procedure adverse events.

    Data is gathered from the patient electronic medical record (EMR).

    Measured: Up to fourteen days.

Questions about this trial

What is this clinical trial studying?

A study testing liposomal bupivicaine in people with Pain, Postoperative, run by United States Naval Medical Center, San Diego 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 8 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 3 Jul 2024. 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.

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?

Total post operative narcotic use in morphine equivalents. (time frame: Up to fourteen days.). 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 3 Jul 2024.
