Use of intramuscular ketamine by paramedics in the management of severely agitated patients.

Abstract

OBJECTIVE: Administration of a sedative agent is required for safe transport of prehospital patients with severe agitation to EDs. Ambulance services in Australasia use ketamine, droperidol or midazolam as first line agent but the optimal agent is uncertain. In Victoria, intramuscular (IM) ketamine is used. The present study aimed to examine the prehospital characteristics and ED outcomes of patients with severe agitation after IM ketamine administration. METHODS: A retrospective review was conducted for patients who received IM ketamine for severe agitation over a 2-year period. Data were sourced from Ambulance Victoria and linked to hospital data. The primary outcome was time to sedation. ..
