About this study
Official title: Efficacy of Intravenous Sub-Dissociative Ketamine Versus Intravenous Morphine in Children With Acute Pain
Pain is common in children presenting to the emergency department but is frequently undertreated, leading to both short- and long-term consequences. Morphine is the standard treatment for children with moderate to severe acute pain, but its use is associated with serious side effects and caregiver and clinician concerns related to opioid administration. The investigators aim to determine if sub-dissociative ketamine is non-inferior to morphine for treating acute pain and a preferable alternative for treating acute pain in children because of its more favorable side effect profile and potential long-term benefits related to pain-related function, analgesic use/misuse, and mental and behavioral health outcomes.
Read the detailed description
Aim 1: To determine if IV sub-dissociative ketamine is non-inferior to IV morphine for decreasing pain intensity in children presenting to an ED with acute pain. The investigators hypothesize that IV sub-dissociative ketamine is non-inferior to IV morphine for decreasing pain intensity in children with acute abdominal pain or an extremity fracture.
Aim 2: To compare the rate of acute (<2 hours) adverse events, including cardiopulmonary adverse events requiring an intervention, associated with IV sub-dissociative ketamine and IV morphine. The investigators hypothesize that there is a smaller proportion of cardiopulmonary adverse events requiring an intervention associated with IV sub-dissociative ketamine compared to IV morphine.
Aim 3: To determine the relationship between ketamine and long-term sequelae of acute pain. The investigators hypothesize that children who receive ketamine will have better levels of pain-related function during the first week following ED presentation and will have greater odds of experiencing more favorable post-traumatic stress, anxiety and depression outcomes 1-6 months after ED presentation compared to children who received IV morphine.

What is being measured
The primary outcome is the main question the study is designed to answer.
Pain intensity
Self-reported pain intensity measured using the Verbal Numerical Rating Scale (VNRS). Scored from 0 to 10. A higher score indicates a worse outcome.
Measured: Up to 240 minutes after completion of study drug administration or until a terminal event occurs
Cardiopulmonary adverse events requiring an intervention
Cardiopulmonary adverse events (e.g., hypoxia, respiratory depression, hypotension) requiring an intervention (e.g., isotonic fluid bolus; vasopressor; chest compression; naloxone; supplemental oxygen; non-invasive positive pressure ventilation; bag-valve-mask ventilation; tracheal intubation)
Measured: Up to 120 minutes after completion of study drug administration or until a terminal event occurs
Pain-related function
Pain intensity and related functional limitations due to pain, measured using the Parents' Postoperative Pain Measure (PPPM). Scored from 0 to 10. A higher score indicates a worse outcome.
Measured: Days 1, 2,3, and 7 after discharge.
Post-traumatic stress
Stress related to the pain experienced measured using the University of California Los Angeles Post-Traumatic Stress Disorder (UCLA PTSD). Scored from 0 to 80. A higher score indicates a worse outcome.
Measured: Baseline (at time of enrollment) and days 7, 30, 90 and 180 after discharge.
Secondary outcomes (10)
Desire of rescue analgesia
Number of participants who indicated that they desired a rescue analgesic
Measured: Up to 120 minutes after completion of study drug administration or until a terminal event occurs
Desire for same analgesic
Number of participants who would want the same analgesic (i.e., study medication) again in the future.
Measured: At 240 minutes after completion of study drug administration or when a terminal event occurs
Depth of sedation
Depth of sedation measured using the University of Michigan Sedation Scale (UMSS). Scored from 0 to 4. 0 is deepest level of sedation (unarousable), 4 is awake and alert.
Measured: Up to 240 minutes after completion of study drug administration or until a terminal event occurs
Adverse events, non-cardiopulmonary
Adverse events that are non-cardiopulmonary and can include (but are not limited to) opioid-related adverse events or those as measured using the Side Effects Rating Scale of Dissociative Anesthetics (SERSDA).
Measured: Up to 120 minutes after completion of study drug administration or until a terminal event occurs
Analgesic/opioid use after discharge
Name, dose and duration of analgesics and/or opioids used to calculate total days of use during the elapsed time since last assessment
Measured: Days 1, 2, 3, 7, 30, 90, and 180 after discharge
Missed school or work
Days of missed school or work related to the chief complaint.
Measured: Day 7 after discharge
Return visit
Number of return visits related to the chief complaint, which can include (but not limited to) return visits to the emergency department or primary care physician
Measured: Day 7, 30, 90, 180 after discharge
Anxiety
PROMIS Anxiety 8a. Scored from 8 to 40. A higher score indicates a worse outcome.
Measured: Baseline (at time of enrollment) and days 7, 30, 90, and 180 after discharge
Depression
Patient-Reported Outcomes Measurement Information System (PROMIS). Scored from 8 to 40. A higher score indicates a worse outcome.
Measured: Baseline (at time of enrollment) and days 7, 30, 90, and 180 after discharge
Substance use
National Institute on Drug Abuse (NIDA) modified assist tool. Scored from 0 to 360. A higher score indicates a worse outcome.
Measured: Baseline (at time of enrollment) and day 30 after discharge

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Ketamine hydrochloride and Morphine sulphate in people with Abdominal Pain and Isolated Extremity Fracture, run by Columbia University at 8 sites 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 4 inclusion and 19 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: looking for participants now, as of the sponsor's last update on 20 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 8 sites 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 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Daniel S Tsze, MD, MPH (917-375-2647, dst2141@cumc.columbia.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Pain intensity (time frame: Up to 240 minutes after completion of study drug administration or until a terminal event occurs). The study lists 4 primary outcomes in all. 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 20 Oct 2026.
