What this trial studies

This phase one trial investigates the safety and feasibility of administering low-dose intravenous ketamine to patients presenting with suicidal ideation in the emergency department. Participants will receive a single dose of 0.2mg/kg of ketamine and will be monitored for two hours for vital signs and symptoms. The study aims to gather preliminary data on the drug's efficacy in reducing depressive and suicidal symptoms, as well as its impact on the length of hospital stay. Surveys will be conducted at various intervals to assess changes in mental health status.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-65 who are acutely suicidal and require inpatient stabilization.

Not a fit: Patients with a history of psychosis, current mania, or other specified medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a rapid and effective intervention for patients experiencing acute suicidal ideation.

How similar studies have performed: Other studies have shown promising results with ketamine for treatment-resistant depression, suggesting potential for success in this novel application.
