About this study

Official title: Laparoscopic Assisted Plane Block (LAPB) Trial: Bupivacaine Versus Liposomal Bupivacaine Versus Standard Local Anesthesia for Post-operative Analgesia

This study attempts to demonstrate improvement in analgesia in a more diverse laparoscopic surgery group with the use of laparoscopic assisted transversus abdominis plane blocks. The investigators will compare bupivacaine (treatment arm 1) versus liposomal bupivacaine (treatment arm 2) versus port site injection of local anesthesia with injection of saline placebo (control). The hypothesis is that liposomal bupivacaine will result in improved analgesia when compared to bupivacaine LAPB and control. The investigators further hypothesize that bupivacaine LAPB will be more effective than the control.

Read the detailed description

Patients will either be pre-screened prior to their pre-operative appointment for eligibility, or screening will occur on the day of surgery. Informed Consent will be obtained from amenable, eligible patients prior to their operation by a member of the research team. A study number will be assigned, and the patient will be randomized to a treatment group. The patients will not be aware to which treatment group they have been randomized.

After consent is obtained and randomization has been completed, the operating room registered nurse will calculate maximum dose of allowable bupivacaine per patient based on body weight. Anesthesia will provide the intravenous lidocaine bolus on induction to all patients without a contraindication to the medication. The port placement will occur using a needle to raise skin/preperitoneal wheal*. Up to 20cc of 1% lidocaine/epinephrine will be divided among all ports and stab incisions. At end of case, no further skin or port-specific preperitoneal anesthetic will be injected unless a skin incision was extended.

For patients randomized to port site injection (Control): 60 cc of sterile, preservative-free, injectable saline will be given as a placebo per the protocol in item 6.

For patients randomized to bupivacaine plain LAPB (Treatment Arm 1): The maximum weight-based dose of plain bupivacaine will be diluted with sterile, injectable, preservative-free saline to a total of 60cc with a maximum of 250mg bupivacaine (regardless of weight) and loaded into a 30cc syringe with a 22g spinal needle (one 30cc syringe used for each side).

For patients randomized to liposomal bupivacaine LAPB (Treatment Arm 2): The maximum dose for adult patients is 266mg (20mL) of liposomal bupivacaine. This will be diluted with 40cc of preservative-free normal saline for injection, per manufacturer recommendations. The solution will then be loaded into a 30cc syringe with a 22g spinal needle and injected in the same fashion as the bupivacaine plain LAPB.

Data collection will include total doses of IV and skin and block anesthetic used, patient weight, number and size of ports, if fascial closure of port site was conducted, and post-operative narcotic medication used up to 48 hours with timing and doses marked, and use of any pain adjuncts (nonsteroidal anti-inflammatory drugs [NSAIDs], acetaminophen, gabapentin, tricyclic antidepressants [TCA], pregabalin, clonidine, etc.) although doses of these medications are not to be recorded.

Provision of home narcotic prescription will be based on a standardized protocol developed by Dartmouth. Based on the past 24 hours of pain medication usage, patients will receive either 15 or 30 tablets of hydrocodone/acetaminophen 5/325mg (or liquid equivalent for bariatric patients). Use of narcotic medications at home will be evaluated at 1 week post-procedure by a member of the research team through a phone survey.

What is being measured

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

  1. Narcotic Usage

    post-operative narcotic usage expressed in morphine equivalents

    Measured: 24 hours

Secondary outcomes (4)
  1. Narcotic Usage

    post-operative narcotic usage expressed in morphine equivalents

    Measured: 7 days

  2. Pain Scores

    Visual Analog Score for pain (1-10)

    Measured: 24 hours

  3. Post-Operative Nausea

    Post-operative nausea will be quantified through chart review by recording the amount of anti-emetic medication administered in the 24 hour period the patient is admitted post-operatively. This will allow objective quantification of nausea in the immediate post-operative period for analysis.

    Measured: 24 hours

  4. Post-operative emesis

    Emesis is recorded as part of the standard intake/output medical charting, and the number of episodes of emesis will be quantified from chart review. This will be analyzed between groups to determine if the intervention has an impact on the number of episodes of post-operative emesis.

    Measured: 24 hours

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Bupivacaine, Exparel 266 milligram Per 20 ML Injection and Saline in people with Opioid Use, run by Santa Barbara Cottage Hospital 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: stopped early, as of the sponsor's last update on 1 Jul 2021. 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. Some participants in this study may receive a placebo. 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: There were not enough attendings/residents working on the study throughout the COVID-19 pandemic in order to enroll the number of patients required to meet statistical significance.). 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?

Narcotic Usage (time frame: 24 hours). 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 1 Jul 2021.
