Short (low-dose) ketamine infusion for managing acute pain in the ED: case-report series

Published:September 25, 2014DOI:https://doi.org/10.1016/j.ajem.2014.09.029

      Highlights

      • We report on 14 patients who received low-dose (0.2-0.4 mg/kg) ketamine infusions in the emergency department for acute pain
      • Thirty-three percent of these patients were on chronic opioid medications and 86% had failed opioid medications administered in the emergency department before getting ketamine
      • Of the 14 cases, 11 had significant improvement, with 2 patients reporting mild adverse effects
      • Low-dose ketamine infusion may be safe and effective for patients who have a history of chronic opioid use or who are refractory to opioid pain medications
