Study of IV Ketamine for Emergency Department Treatment of Adolescent Suicidal Ideation
Canada20 participantsStarted 2024-01-15
Plain-language summary
Approximately 20% of Canadian adolescents experience thoughts of suicide, or suicidal ideation (SI), and suicide is the second leading cause of death among Canadians aged 15-19 years. The emergency department at CHEO sees approximately four patients per day with SI. Even though this is a medical emergency, there are no fast-acting treatments available.
Ketamine is a medication that is commonly used to safely sedate children who require painful procedures in the emergency department. For nearly ten years, intravenous ketamine has also been shown to rapidly reduce SI in adults. However, ketamine as a treatment for SI has never been studied in adolescents. The primary study objective is to pilot a clinical trial that investigates intravenous ketamine to emergently treat SI in adolescents.
If intravenous ketamine can relieve symptoms of SI for youth, this would have tremendous effects on patients and would dramatically change how physicians treat adolescent mental health emergencies. If ketamine is effective for several weeks, as it is in adults, it will help temporize patients until they receive more long-term psychiatric care. At the system level, it has the potential to reduce emergency visits and lengthy admissions. The investigators feel that the results of this study will be generalizable to pediatric centres across Canada and beyond.

Inclusion criteria
. Responds "yes" to Ask Suicide Screening Question (ASQ) #5 at triage, which asks; "Are you having thoughts of killing yourself right now?"
. Moderate to severe suicidal ideation, defined as score ≥ 3 on the first 5 questions of the Beck Scale for Suicidal Ideation (SSI5)
. Age 12 to 17 years, inclusive
. Medically clear (deemed fit for participation in the trial), as judged by the treating physician. Minimum criteria required to be deemed medically clear are: a) No evidence of serious physical injury requiring urgent intervention b) No evidence of acute ingestion requiring monitoring, blood tests, imaging or ECG or in the context of acute ingestion they have satisfied the requisite number of hours of post-ingestion monitoring with no further need for intervention.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
