Trial summary

The purpose of this study is to quantify the total blood serum levels of bupivacaine in OrthoPAT® collected blood 2 hours and 5 hours postoperatively. Hypothesis: Filtered blood from the OrthoPAT® autotransfusion system contains low or undetectable levels of bupivacaine hydrochloride (HCL). Read more about this study

About this study

The purpose of this study is to quantify the total blood serum levels of bupivacaine in OrthoPAT® collected blood 2 hours and 5 hours postoperatively.

Hypothesis: Filtered blood from the OrthoPAT® autotransfusion system contains low or undetectable levels of bupivacaine hydrochloride (HCL). Reinfusion of collected blood from the OrthoPAT® device when used in conjunction with periarticular bupivicaine injections will not pose a bupivocaine toxicity risk to patients undergoing a total joint arthroplasty.

Read the detailed description

Total joint arthroplasty (TJA) is a commonly performed surgical procedure that can result in considerable postoperative pain which can limit social and functional recovery and a return to quality of life. Traditionally, pain control following TJA has been conducted with parenteral and oral narcotics. Recently, a number of studies have demonstrated the efficacy of multimodal analgesia following a variety of surgical procedures.1-2 These multimodal regimens vary and consist of any number of medications including narcotics, non-steroidal anti-inflammatories, anti-epileptics, and peripheral nerve blocks among others. These multimodal regimens have been associated with a reduction in the use of opioid analgesics, leading to fewer opioid-associated adverse events.3-5 One of the newest modalities introduced on the market is liposomal bupivacaine, trade name Exparel. The advertised advantage of liposomal bupivacaine compared with bupivacaine HCL is a longer duration of analgesia owing to gradual release from the liposomes. Liposomal bupivacaine is employed in a periarticular injection at the conclusion of TJAs to aid in post-operative pain control.

Patients receive a periarticular injection of liposomal bupivacaine intra-operatively during TJA. At the conclusion of the procedure, a specialized intra-articular drain (OrthoPAT®) is placed. The OrthoPAT® perioperative autotransfusion system collects the patient's blood in the immediate postoperative period and then allows for it to be transfused to the patient while on the floor.

A potential risk, although low, is the concern for bupivicaine toxicity. Toxicity from bupivicaine is associated with central nervous system issues (seizures) and cardiac toxicity. Toxicity is dose dependent and recommended levels should not exceed 400mg/24 hr period. With autotransfusion, there is a theoretical concern that blood, potentially with increased levels of bupivicaine, could be reinfused into the vascular system and create toxicity.

What participants receive

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

  • periarticular bupivicaine and liposomal bupivicaineDrug

    Also called Exparel

    Participants will receive Exparel (liposomal bupivacaine). Exparel is a FDA approved product. Exparel is an extended-release formulation of bupivacaine consisting of microscopic lipid-based particles that diffuse over an extended period. The result is pain relief that can last up to 96 hours after surgery. Extended-release liposomal bupivacaine-based analgesics were shown to provide extended pain relief and decrease opioid (pain medication) use. At the conclusion of the total joint arthroplasty procedure, Exparel is administered via injection into the joint (periarticular bupivicaine and liposomal bupivicaine).

What is being measured

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

  1. Change in Blood Serum Levels of Bupivocaine From Baseline

    Bupivocaine levels measured in the blood that is collected in a surgical drain post surgery. Blood samples will be tested for change in serum bupivicaine levels from baseline.

    Measured: Change from baseline at 2 and 5 hours post-dose

Questions about this trial

What is this clinical trial studying?

An observational study of Knee Pain Arthritis, run by OrthoCarolina Research Institute, Inc. at 4 sites 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 2 inclusion and 5 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 30 Nov 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites 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?

Yes. Results are posted in the registry (first posted 30 Nov 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?

Change in Blood Serum Levels of Bupivocaine From Baseline (time frame: Change from baseline at 2 and 5 hours post-dose). 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 30 Nov 2017.
