Ketamine for Pain in the Emergency Department
A Phase 4 study testing Ketamine Injectable Product in people with Acute Pain, run by Hackensack Meridian Health at 1 site in United States.
Trial summary
This study will prospectively compare the mean Numerical Rating Scale (NRS) pain score reduction amongst three recommended dosing strategies of intravenous ketamine (0.1 mg/kg, 0.2 mg/kg, and 0.3mg/kg) for acute pain in the emergency department (ED).This study will also examine the frequency of adverse events… Read more about this study

About this study
Official title: Comparison of Ketamine 0.1 mg/kg, 0.2 mg/kg, and 0.3 mg/kg Intravenous Doses for Acute Pain in the Emergency Department: A Prospective, Randomized, Double-blind, Active-controlled, Clinical Trial
This study will prospectively compare the mean Numerical Rating Scale (NRS) pain score reduction amongst three recommended dosing strategies of intravenous ketamine (0.1 mg/kg, 0.2 mg/kg, and 0.3mg/kg) for acute pain in the emergency department (ED).This study will also examine the frequency of adverse events secondary to ketamine including fatigue, dizziness, nausea, headache, feeling of unreality, changes in hearing or vision, mood changes, generalized discomfort, and hallucinations, changes in vital signs. Subgroups for exploratory analysis based on the need for rescue analgesia within two hours of ketamine administration, adequate pain relief, previous opioid tolerance, and age (adults < 65 years old and > 65 years old).
Read the detailed description
A literature review was performed that searched for randomized clinical trials involving ketamine IV boluses for acute pain in the Emergency Department. Studies involving continuous infusions or intranasal routes of ketamine administration were not included. Thirteen randomized clinical trials were identified meeting this criteria. None of these trials directly compared ketamine doses within the 0.1-0.3 mg/kg range for pain score reduction and adverse events. Many of these trials concluded with the recommendation that further studies were needed to evaluate the optimal dosing of ketamine for acute pain and determine which populations are most ideal for its use. This study will be the first to evaluate ketamine for acute pain in the emergency department at standard of care doses (0.1 mg/kg, 0.2 mg/kg, and 0.3 mg/kg IV) to determine which dose correlates with the most efficacy and safety.
This study will include the following procedures:
- Patient consent, screening, and enrollment will be performed by the treating resident or attending who will remain blinded
- Patient will be assigned a subject number
- Treating resident or attending will notify the ED pharmacist that a patient has been enrolled in the trial
- ED pharmacist will notify the IV room and place the study drug order
- Either the ED pharmacist or a pharmacy supervisor will randomize the subject based on the predetermined randomization list
- Study drug will be prepared as 0.1 mg/kg, 0.2 mg/kg, or 0.3 mg/kg IV dose in a 100 mL solution of dextrose 5% or sodium chloride 0.9%
- ED pharmacist will promptly deliver the study drug to the ED
- Baseline vital signs will be assessed prior to starting the study drug infusion
- Study drug will be administered via IV infusion over 20 minutes
- Treating resident or attending will reassess the patient at 15 minutes from the end of infusion, at 30 minutes from the end of infusion, and then every 30 minutes for up to 120 minutes or until discharge, whichever is sooner

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Ketamine Injectable ProductDrug
Three different doses of ketamine will be administered.
| Study group | Role | What they receive |
|---|---|---|

Evaluated for side effects for 2 hours following completion of ketamine infusion. Receives: Drug: Ketamine Injectable Product |
| Arm 1: 0.2 mg/kg ketamine | Active comparator | 0.2 mg/kg in a 100 mL solution of dextrose 5% or sodium chloride 0.9% will be give after patient consent and enrollment in the study, vitals are followed (heart rate, systolic blood pressure and respiratory rate) for 2 hours following completion of ketamine infusion.

What is being measured
The primary outcome is the main question the study is designed to answer.
Pain Score
Pain score using Numerical Rating Scale (NRS) post ketamine infusion. The Numerical Rating Scale (NRS) ranges from 0-to-10 with 0 being no pain and lower numbers representing less pain, so in this case lower numbers will represent better outcomes.
Pain scores were reported at baseline and then at 15 min/30 min/60 min/90 min and 120 minutes post-infusion.
Measured: Within 2 hours post infusion completion
Secondary outcomes (1)
Adverse Events
Frequency of adverse events secondary to ketamine including fatigue, dizziness, nausea, headache, feeling of unreality, changes in hearing or vision, mood changes, generalized discomfort, and hallucinations, changes in vital signs.
Adverse events were reported at baseline and then at 15 min/30 min/60 min/90 min and 120 minutes post-infusion.
Measured: Within 2 hours post infusion completion

Pain Score
Time frame: Within 2 hours post infusion completion
Pain score using Numerical Rating Scale (NRS) post ketamine infusion. The Numerical Rating Scale (NRS) ranges from 0-to-10 with 0 being no pain and lower numbers representing less pain, so in this case lower numbers will represent better outcomes. Pain scores were reported at baseline and then at 15 min/30 min/60 min/90 min and 120 minutes post-infusion.

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 7 Jun 2023). 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 Score (time frame: Within 2 hours post infusion completion). 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 NCT03896230, which also lists 25 linked publications.
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 7 Jun 2023.
