AI Article Synopsis
- The study aims to assess the effectiveness of intramuscular (IM) ketamine in controlling violent behavior compared to standard treatments (IM benzodiazepines and antipsychotics) in emergency department patients.
- Approximately 184 patients will participate in a randomized trial, receiving either ketamine or a combination of midazolam and haloperidol, with the primary focus on the time it takes to achieve behavioral control as measured by the Richmond Agitation-Sedation Scale.
- This research is unique as it will be the first randomized controlled trial to directly compare the use of ketamine with conventional medications for managing psychomotor agitation in emergency settings.
Article Abstract
Background: The rapid control of patients presenting to the emergency department (ED) with psychomotor agitation and violent behavior is paramount for the safety of patients and ED staff. The use of intramuscular (IM) ketamine in the pre-hospital and ED settings has demonstrated promising preliminary results to provide rapid and safe behavioral control. A prospective, randomized controlled trial is required to measure the potential superiority of IM ketamine compared to current standard care (IM benzodiazepines plus antipsychotics).
Methods: This will be a parallel, prospective, randomized, controlled trial of 5 mg/kg IM ketamine compared to a combination of 5 mg IM midazolam and 5 mg IM haloperidol. The study will enroll approximately 184 patients, randomized equally to two study arms. There will be one study visit during which study medication will be administered and assessments will be completed. A follow-up safety visit will occur on day 3. The primary objective of this study is to compare IM ketamine to a combination of IM midazolam and haloperidol with regards to the time required for adequate behavioral control, in minutes, in patients presenting to the ED with psychomotor agitation and violent behavior, as measured by the Richmond Agitation-Sedation Scale (RASS).
Discussion: We present a novel study to determine whether ketamine is a rapid and safe option, compared to a combination of midazolam and haloperidol for the sedation of patients presenting to the ED with psychomotor agitation and violent behavior. To our knowledge, this study is the first randomized controlled trial to compare ketamine to current standard care for this indication. We have attempted to address numerous logistical issues with the design of this study including a waiver of consent, ensuring adequate blinding of outcome assessors, patient enrolment, and data monitoring.
