About this study

Official title: A Double Blind, Randomized Clinical Trial Comparing Postoperative Narcotic Usage in Patients Receiving Periarticular Liposomal Bupivicaine vs. Those Patients Receiving Standard Periarticular Joint Injections

This study seeks to determine whether a new sustained-release local anesthetic solution (Exparel - Liposomal Bupivacaine) injected into the soft tissues around the joint after surgery will decrease opioid consumption and adverse events in opioid-tolerant patients presenting for total knee arthroplasty. The research hypothesis is that the Exparel (study) group will use less opioid in the first 48 hours post-operatively than the control group.

Read the detailed description

Opioids have been prescribed with increasing frequency for non-acute, non-cancer pain in the last 15 years. Because of this, opioid tolerance in the general population has grown markedly, and opioid tolerant patients can be especially difficult to manage in the perioperative period. In general, they require much higher doses of opioids to obtain similar levels of pain-control compared to opioid-naïve patients and are susceptible to respiratory depression and other adverse events. This study seeks to determine whether a new sustained-release local anesthetic solution (Exparel - Liposomal Bupivacaine) injected into the soft tissues around the joint after surgery will decrease opioid consumption and adverse events in opioid-tolerant patients presenting for total knee arthroplasty.

What participants receive

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

  • (Bupivacaine Liposome Injectable Suspension)Drug

    Also called EXPAREL®

    Instead of injecting the standard joint injection for a case of total knee arthroplasty, Exparel-lipsomal bupivacaine will be administered at the end of the surgery.

  • Standard PreparationDrug

    Also called Standard Periarticular Joint Injection

    A standard joint injection of 100ml (Clonidine 80 mcg, Epinephrine 0.5mg, Ketorolac 30mg, Ropivacaine 246.25mg, and Sodium Chloride 0.9% 48.45 ml) will be injected into the soft tissues around the joint after surgery.

What is being measured

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

  1. 48 Hour Post-surgical Opioid Use

    A comparison of group means between the control group and study group with regards to 48 hour opioid use.

    Measured: 48 hours

Secondary outcomes (4)
  1. Recovery Room Opioid Use

    Post anesthesia care unit (recovery room) opioid use in total mg morphine IV equivalent in comparison of standard knee injection post-operatively.

    Measured: Up to 48 hours

  2. Average Daily Opioid Use During Admission

    Opioid use will be monitored daily from the time of admission in comparison of standard knee injection post-operatively.

    Measured: Up to 48 hours

  3. Average Daily Patient Pain Score

    Examining the average daily patient pain score in comparison of standard knee injection post-operatively. The measure is the Visual-Analog-Scale (VAS) for subjective pain reporting. The minimum 0 (no pain) and the maximum is 10 (worst pain imagineable). There is only one measure in the scale (i.e. there are no subscales). Lower scores on the VAS scale equate to less pain and are therefore desirable.

    Measured: Up to 48 hours

  4. Post-operative Complications

    Examining the post-operative complication in comparison of standard knee injection post-operatively.

    Measured: Up to 1 month

A Phase 4 study testing (Bupivacaine Liposome Injectable Suspension) and Standard Preparation in people with Arthroplasty, Replacement, Knee, run by University of California, Irvine 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 10 inclusion and 7 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 7 Jul 2017. 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 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?

Yes. Results are posted in the registry (first posted 7 Jul 2017). 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?

48 Hour Post-surgical Opioid Use (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 NCT02682498, which also lists 14 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 7 Jul 2017.
