About this study

Official title: The Effect of the Combined Use of Naloxone and Tramacet on Postoperative Analgesia in Elderly Patients Having Joint Replacement Surgery: a Randomized Controlled Study.

Patients over 70 years of age, scheduled for joint replacement surgery will be randomized to tramacet/ naloxone plus morphine PCA or to morphine PCA to assess quality of analgesia in the postoperative period.

The primary objective is to determine opioid use during combined use of oral tramacet and naloxone infusion perioperatively in elderly patients (70 yrs and older) having elective knee/ hip arthroplasty under spinal anesthesia.

Secondary objectives are to determine the incidence VAS scores ≥4 and adverse effects such as nausea, vomiting, sedation, respiratory depression, pruritus, confusion, and time of independent mobilization.

Hypothesis: Perioperative naloxone infusion and tramacet provides adequate analgesia in elderly patients undergoing total knee/hip arthroplasty and is associated with 80% reduction in opioid use and reduced opioid-induced side effects.

Being tested
tramacet, naloxone, tramacet, Acetaminophen

What participants receive

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

  • tramacet, naloxoneDrug

    Also called tramadol/acetaminophen

    Group A: oral tramacet 2 tablets preoperatively, then 2 tablets every 6 hours for 5 days then 1-2 tablets of tramacet prn to a maximum of 8 tablets per day. A naloxone infusion will started preop at 0.25ug/kg/hr and will continue during patient's stay in hospital (an equivalent of 400ug over 24 hours in a 70 kg man). Infusion discontinued 1 hour before patient discharge. All the patients in groups A and B will be provided Morphine PCA for the duration of their hospital stay. Use of morphine PCA will be noted.Oral celebrex 200mg will be given to all the patient twice a day for five days as per our standard practice. All patients will receive peri-articular infiltration with local anesthetic solution intraoperatively by the surgeon as per our standard practice.

  • tramacetDrug

    Also called tramadol/acetaminophen

    Group B: oral tramacet 2 tablets preop,then 2 tablets every 6 hours for five days(or until discharge. Patient VAS after discontinuation of morphine PCA may dictate addition of oral narcotic oxycodone after discharge). Group also receives saline infusion at 4-6mls/hour during hospital stay.All patients in groups A and B will have Morphine PCA during hospital stay. Use of morphine PCA will be noted. Oral celebrex 200mg will be given to all the patient twice a day for five days as per our standard practice. All patients will receive peri-articular infiltration with local anesthetic solution intraopby the surgeon as per our standard practice.

  • AcetaminophenDrug

    Also called Tylenol

    Group C will receive oral Acetaminophen tablets 1 gm preoperatively and subsequently 6 hourly plus an infusion of saline (placebo) at a rate of 4-6mls / hour for the duration of their stay. Oral celebrex 200mg will be given to all the patient twice a day for five days as per our standard practice. All patients will receive peri-articular infiltration with local anesthetic solution intraoperatively by the surgeon as per our standard practice. The Visual Analogue Scale, the Ramsay Sedation Score and the Mini Mental State Exam will be used to assess the patients for pain, sedation and confusion every 6 hours while in hospital.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing tramacet, naloxone, tramacet and Acetaminophen in people with Hip Arthroplasty and Knee Arthroplasty, run by London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's at 1 site in Canada.

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 5 inclusion and 6 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 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 Canada. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Morphine use / day (time frame: per day). 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 2017.
