About this study

Official title: Safety and Efficacy of Cocktail Periarticular Injection for Pain Management in Simultaneous Bilateral Total Knee Arthroplasty- A Prospective, Randomized Trial

We investigated the safety and efficacy of the bilateral periarticular cocktail injection at a reduced dosage in patients undergoing simultaneous bilateral total knee arthroplasty.

Read the detailed description

It is hypothesized that intraoperative periarticular injection with cocktail analgesics can reduce postoperative parenteral narcotics use and improve patient satisfaction following total knee arthroplasty.

A prospective, randomized trial is conducted to testify the hypothesis above by recruiting patients who go through simultaneous bilateral TKA and observing their postoperative analgesic consumption, visual analog scores and functional recovery. Potential side-effects of the multimodal drugs is also under observation.

Being tested
ropivacaine, fentanyl, adrenaline

What participants receive

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

  • ropivacaine, fentanyl, adrenalineDrug

    Also called Naropin, AstraZeneca

    The patients in the cocktail analgesia group received an injection of 200mg ropivacaine, 100ug fentanyl, and 0.25mg adrenaline into knee collateral ligaments, posterior aspect of the capsule, quadriceps tendon, patellar tendon, fat pad, periosteum, and synovium, along with PCIA morphine postoperatively.

cocktail analgesiaExperimentalThe local infiltration mixture of ropivacaine, fentanyl, adrenaline is used intra-articularly during operation. The patients in the cocktail analgesia group received an injection of 200mg ropivacaine, 100ug fentanyl, and 0.25mg adrenaline into knee collateral ligaments, posterior aspect of the capsule, quadriceps tendon, patellar tendon, fat pad, periosteum, and synovium, along with PCIA morphine postoperatively.
Receives: Drug: ropivacaine, fentanyl, adrenaline
no cocktail injectionNo interventionThe patients in the no cocktail injection group received PCIA morphine postoperatively.

What is being measured

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

  1. To evaluate the Morphine consumption and PCIA duration

    Measured: 12 hours to 3 days after the surgery

Secondary outcomes (2)
  1. To evaluate the visual analog scale (VAS) in each group patients underwent total knee arthroplasty

    Measured: 4 hours to 5 days after the surgery

  2. Function recovery evaluation for patients received surgery

    Measured: 1, 3 and 5 days after the surgery

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing ropivacaine, fentanyl, adrenaline in people with Pain, Postoperative, run by Peking Union Medical College Hospital at 1 site in China.

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 1 inclusion and 4 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 28 Aug 2015. 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 China. 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?

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?

To evaluate the Morphine consumption and PCIA duration (time frame: 12 hours to 3 days after the surgery). 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 28 Aug 2015.
