Multiple studies have shown ketamine to be safe and effective agent for acute pain syndromes. RSEs classically result in severe pain that can be difficult to control, despite use of opioids, non-opioid analgesics, and positioning techniques, including splinting and elevation. Furthermore, the ongoing opioid epidemic pushes clinicians to explore non-opioid agents to avoid unnecessary exposure of patients to these high-risk medications. At least one small study has shown ketamine to be safe in rattlesnake envenomated patients.
