Low-Dose Ketamine for Acute Pain

R.E.B.E.L.EM -10 April, 2017 - Post Peer Reviewed By: Rob Bryant
"Background: Ketamine’s role in the ED has expanded in recent years. The clinical reasons for this make it easy to understand why, and include analgesia, amnesia, and anesthesia. Amazingly, ketamine does not only reduce acute pain, but it also decreases persistent chronic and neuropathic pain as well. More importantly, use of low-dose ketamine (0.1 – 0.3 mg/kg IV) has been demonstrated to be opioid sparing. Some of the major issues with IV push low-dose ketamine include its adverse effects, such as feelings of unreality, nausea/vomiting, and dizziness. Many emergency medical providers have anecdotally noticed a decrease in adverse effects when ketamine is given slowly. In the paper we are reviewing today, the authors tried to see if increasing the duration of the ketamine from IV push (3 – 5 min) to a slow infusion (10 – 15 min) could mitigate some of these effects, while maintaining analgesic efficacy...
Author Conclusion: “Low-dose ketamine given as a short infusion is associated with significantly lower rates of feeling of unreality and sedation with no difference in analgesic efficacy in comparison to intravenous push.”
Clinical Take Home Point: Low dose ketamine of 0.3mg/kg, mixed into 100mL of Normal Saline given over slow infusion (15 minutes) has a decreased side effect (i.e hallucinations or dizziness) and equal analgesic profile when compared to IV push (5 minutes) low dose ketamine."
