About this study

Official title: Randomized Blinded, Placebo Controlled Trial of Intrapoperative Ketamine for Patients Undergoing Total Joint

Prospective randomized double blinded, placebo controlled study that will evaluate the effect of intra-operative ketamine administration on post-operative analgesic requirements and self-reported pain in patients undergoing total hip and total knee arthroplasty who demonstrate high levels of pain catastrophizing.

Read the detailed description

Pain management can be one of the most challenging aspects of care for total joint arthroplasty patients. Poor post-operative pain control can lead to poor patient satisfaction and functional outcomes. Moreover, prolonged post-operative opioid utilization for post-operative pain is associated with substantial adverse sequelae. Identifying patients at high risk for poor post-operative pain control, and implementing strategies to improve pain management in this population is of utmost importance. One patient feature that has been shown to reliably predict poor post-operative pain management is pain catastrophizing. Currently available self-reported metrics such as the pain catastrophizing scale allow for pre-operative identification of patients who exhibit high levels of pain catastrophizing. Furthermore, there currently exist strategies which may effectively improve post-operative pain management in this population. One such strategy is "pre-emptive" analgesia utilizing ketamine administered at the time of surgery. Ketamine is commonly utilized in the treatment of both acute and chronic pain, and is believed to reduce pain intensity through a complex mechanism involving opioid receptors and excitatory neurotransmitters. It has been utilized in a variety of surgical procedures and has consistently been shown to reduce acute post-operative pain and analgesic consumption as long as 6 months after surgery, without a significant incidence of medication related side effects. To date, no study has evaluated the use of ketamine for total joint arthroplasty patients who demonstrate high levels of pain catastrophizing. We aim to study the effect of intra-operative ketamine administration on post-operative analgesic requirements and self-reported pain in patients undergoing total hip and total knee arthroplasty who demonstrate high levels of pain catastrophizing.

What is being measured

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

  1. Total Morphine consumption during the first 48 hours post surgery

    Morphine consumption will be measured in a pain diary for 6- weeks post-surgical procedure. Decreased is morphine consumption will indicate effectiveness of ketamine administration

    Measured: Daily for six weeks

Secondary outcomes (4)
  1. Hip Disability and Osteoarthritis Outcome Score for Joint Replacement (HOOS, JR.)

    six question questionnaire measuring joint specific pain and physical function, scored by summing the raw response (range 0-24) and then converting it to an interval score using the table provided below. The interval score ranges from 0 to 100 where 0 represents total hip disability and 100 represents perfect hip health.

    Measured: Pre-operation, post-operation at 6 weeks, 12 weeks, and 6 months

  2. Knee Disability and Osteoarthritis Outcome Score for Joint Replacement (KOOS, JR.)

    Seven question questionnaire measuring joint specific pain and physical functionscored by summing the raw response (range 0-28) and then converting it to an interval score using the table provided below. The interval score ranges from 0 to 100 where 0 represents total knee disability and 100 represents perfect knee health.

    Measured: Pre-operation, post-operation at 6 weeks, 12 weeks, and 6 months

  3. Patient-Reported Outcomes Measurement Information System (PROMIS-10)

    patient-reported questionnaire in which the response options are presented as 5-point (as well as a single 11-point) rating scales. The results of the questions are used to calculate two summary scores: a Global Physical Health Score and a Global Mental Health score. The higher the score the healthier the subject is compared to the general population.

    Measured: Pre-operation, post-operation at 6 weeks, 12 weeks, and 6 months

  4. Pain Catastrophizing Scale (PCS)

    The PCS is a 13 item scale, with each item rated on a 5-point scale: 0 (Not at all) to 4 (all the time). The PCS is broken into three subscales being magnification, rumination, and helplessness. The higher the score, the more catastrophizing thoughts are present.

    Measured: post-operation at 6 weeks, 12 weeks, and 6 months

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Ketamine in people with Pain, Postoperative and Arthroplasty Complications, run by Dartmouth-Hitchcock Medical Center 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 1 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 27 Sep 2024. 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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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?

Total Morphine consumption during the first 48 hours post surgery (time frame: Daily for six weeks). 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 27 Sep 2024.
