About this study

Official title: The Effectiveness of Small Doses of Ketamine With Morphine on Decreasing Pain Responses During Open Wound Care

This is a randomized double-blind study to determine if the administration of a small-dose of ketamine (an anesthetic)added to morphine (an opioid) contributes to reducing pain intensity during open wound care procedure (WCP)in patients who have had a traumatic injury and are in an Intensive Care Unit. Patients will be randomized to receive morphine plus saline (a placebo) or morphine plus ketamine before the WCP. The second time the patient is scheduled for WCP (no less than 24 hours), patients will be crossed over to receive the treatment they did not receive the first time. It is hypothesized that patients who receive the combination of morphine and ketamine will have better pain control during the procedure than patients who just receive morphine.

Read the detailed description

An open wound care procedure causes pain and sometimes the use of medication such as morphine alone does not adequately help to alleviate pain during this procedure. This study is being done to learn if the administration of another medication named ketamine by the vein in addition to morphine is more effective in alleviating pain during the wound cleansing procedure than the administration of morphine alone. Patients will be eligible for the study if they are 21 years and older, have an open surgical or traumatic wound with a duration of no more than 10 days, had a wound pain intensity score more than 3 in a scale of 0 to 10 where 0 is no pain and 10 is the worst pain imaginable during a previous wound care procedure, and have an intravenous access.

A total of 50 patients with these same characteristics are expected to take part in this study. Patients who agree to take part in this study will, one day, receive receive an injection via the vein of morphine 0.05 mg per kilogram of their weight (maximum dose of 4 mg) and another of ketamine 0.25 mg per kilogram of their weight prior receiving the wound care procedure and, on the other day, will receive an injection via the vein of morphine 0.1 mg per kilogram of their weight (maximum dose of 8 mg) and another of saline prior receiving the wound care procedure. They will not be able to know if they receive ketamine or saline the first time or second time.

Ketamine is a drug approved by the U.S. Food and Drug Administration (FDA) for anesthesia but not approved to provide analgesia (relieve pain). However, small doses of ketamine are used (out of its indications) in the clinical area to provide analgesia, and its analgesic properties have been studied by many researchers.

Before the wound care procedure subjects will be asked to rate their wound pain intensity at rest at that moment and in the past 24 hours (including "worst" and "average" pain), overall pain intensity at rest at this moment and "worst" and "average" in the past 24 hours using a 0 to 10 scale where 0 is no pain and 10 is the worst pain imaginable. They will be given a list of common words that might describe their pain, and a body outline to indicate where the pain is. In addition, they will be asked to rate their level of sleepiness using a 0 to 10 scale where 0 is not at all sleepy and 10 is extremely sleepy.

After removing the outer dressing, patients will be tested for pain sensitivity around the wound with a thin, short length of plastic (like a little straw), which will be pressed against their skin from the outside of the wound towards the wound and they will be asked to report a distinct change in perception. The first point where a "painful", "sore", or "sharper" feeling occurs will be marked in the skin to measure the distance of this mark to the wound. If no change in perception occurs, stimulation will be stopped 0.5 cm from the wound. This measure is experimental.

Immediately after the wound care procedure the following will be measured: (1) "worst" wound pain intensity experienced during the wound care procedure, (2) description of pain quality during the wound care procedure, (3) level of sleepiness, (4) side effects such as unpleasant sensation will be measured using a 0 to 10 scale, where 0 means no unpleasant sensation at all and 10 means extremely unpleasant sensation, and finally (5) pain sensitivity around the wound using a thin, short length of plastic.

The length of time needed to take part in this study will depend on how long the wound care procedure takes. The time could be approximately 45 minutes to 60 minutes (1 hour) per visit and 90 minutes (1½ hour) to 120 minutes (2 hours) in total for the study because 2 days are needed to complete the study.

What is being measured

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

  1. Pain Intensity

    The degree of pain described by participants on a numeric rating scale of 0 to 10, where 0 = no pain and 10 = worst pain imaginable

    Measured: Immediately after the wound care procedure

Secondary outcomes (1)
  1. Wound Pain Quality

    Short-form McGill Pain Questionnaire. The questionnaire has 15 adjectives to describe the pain. Each is rated on a 4-point scale (i.e., none, mild, moderate, or severe. Total wound pain quality score can range from 0 to 45.

    Measured: Immediately after the procedure

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Morphine plus Ketamine in people with Wound Care and Pain Intensity, run by University of California, San Francisco at 2 sites in 2 countries.

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 4 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 26 Mar 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States, Puerto Rico. 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?

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?

Yes. Results are posted in the registry (first posted 26 Mar 2024). 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?

Pain Intensity (time frame: Immediately after the wound care procedure). 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 NCT00701909, which also lists 1 linked publication.

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 26 Mar 2024.
