About this study

Official title: Intravenous Sub-dissociative Dose Ketamine Injection Versus Infusion for Analgesia in the Emergency Department: A Prospective, Randomized, Double-blind Placebo Controlled Trial

Objective: The purpose of this study is to determine if administering ketamine as an intravenous (IV) infusion over 15 minutes, as compared to an IV push, will decrease adverse drug reactions without attenuating its analgesic effects.

Study design: prospective, randomized, controlled, double-blind trial.

Read the detailed description

Objective: The purpose of this randomized, controlled, double-blind trial is to evaluate if sub-dissociated dose ketamine given as an infusion versus an intravenous (IV) push over 1 minute has fewer and/or less severe adverse drug reactions and provides equivalent analgesia for patients with moderate to severe pain in the emergency department (ED).

Study design: Prospective, randomized, controlled, double-blind trial

Participants: Research assistants will recruit patients ≥18 years old with moderate to severe pain (NRS≥5) and an anticipated stay in the emergency department ≥1 hour. A sample size calculation was performed based on prior data which suggests that 60% of IV push arm and 20 % of infusion arm will have adverse drug reactions. investigators assume an alpha of 0.05 and a power of 0.8, which results in 56 patients needing to be enrolled.

Intervention: After a trained research assistant obtains written informed consent, pharmacists will randomize the participants to the IV push or IV infusion arm of the study. All patients will be placed on a cardiac monitor. All patients will receive and IV push over 1 minute and a 100 mL normal saline minibag over 15 minutes.

In the IV push arm, pharmacists will provide to the nurse ketamine 0.3 mg/kg in a 10 mL syringe and a 100 mL normal saline minibag. The nurse will start the minibag of normal saline and then administer the IV push of ketamine over 1 minute.

In the IV infusion arm, pharmacists will provide to the nurse ketamine 0.3 mg/kg in a 100 mL normal saline minibag and a 10 mL syringe of normal saline. The nurse will start the minibag of normal saline and then administer the IV push over 1 minute.

Data collection: The trained research assistant will collect data on the patients' pain scores, adverse drug reactions (presence, severity, and how bothersome they are), and vital signs.

Statistical analysis: Investigators will perform descriptive statistics, compare the proportion of patients with side effects, compare the severity of the side effects scores, and compare how bothersome the side effects.

What is being measured

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

  1. Side Effects

    The difference in percentage of participants endorsing side effects between each arm of the study over 60 minutes.

    Measured: 0 - 60 minutes

Secondary outcomes (4)
  1. Side Effects

    The difference in percentage of participants endorsing side effects between each arm of the study at 5, 10, 15, 20, 30, 45, and 60 minutes.

    Measured: 5, 10, 15, 20, 30, 45, 60 minutes

  2. Side Effect Severity

    The difference in severity of side effects (0 - 4) experienced by participants in each arm of the study at 5, 10, 15, 20, 30, 45, and 60 minutes. 0 indicates no side effects and 4 most severe side effects.

    Measured: 5, 10, 15, 20, 30, 45, 60 minutes

  3. How Bothersome Are the Side Effects?

    The difference in how bothersome (0, not bothersome, to 4, very bothersome, on the Side Effect Rating Scale for Dissociative Anesthetics "SERSDA") the side effects experienced by participants in each arm of the study are at 5, 10, 15, 20, 30, 45, and 60 minutes.

    "0" (no side effects), "1" (weak), "2" (moderate), "3" ("bothersome") to "4" (very bothersome)

    Measured: 5, 10, 15, 20, 30, 45, 60 minutes

  4. Reduction in Pain on Numeric Rating Scale.

    The difference in pain numeric rating score (NRS 0-10) experienced by participants in each arm of the study at 5, 10, 15, 20, 30, 45, and 60 minutes.

    Pain numeric rating scale from 0 (no pain) to 10 (maximal pain).

    Measured: 5, 10 , 15, 20, 30, 45, 60 minutes

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ketamine IV Infusion and Ketamine IV push in people with Pain, run by Alameda Health System 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 2 inclusion and 7 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 17 Apr 2020. 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. 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?

Yes. Results are posted in the registry (first posted 17 Apr 2020). 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?

Side Effects (time frame: 0 - 60 minutes). 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 NCT02916927, 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 17 Apr 2020.
