Domany Y, Shelton RC, McCullumsmith CB. Ketamine for acute suicidal ideation. An emergency department intervention: A randomized, double-blind, placebo-controlled, proof-of-concept trial. Depress Anxiety. 2020 Mar;37(3):224-233. doi: 10.1002/da.22975. Epub 2019 Nov 16. PMID: 31733088.
Highlights:
- A single dose of IV ketamine produced effective and rapid reductions in suicidal ideation in as little as 90 minutes.
- 88% patients in the ketamine group had achieved remission of suicidal ideation.
- Ketamine is safe and well tolerated.
Results:
Nine subjects were randomized to each group. There were no differences between groups at baseline in any demographic or assessment scales. A reduction in suicidal ideation was noted at 90-180 min (p < .05). Ninety minutes after infusion, 88% of the ketamine group had achieved remission of suicidal ideation compared with 33% in the placebo group (p < .05). No serious adverse events were noted.
Conclusions:
Ketamine was safe and effective for rapid reduction in suicidal ideation in depressed, highly suicidal subjects presenting to the emergency department. Our results support further study of ketamine for acute suicidal ideation.
