High-Dose Sedation and Analgesia During Extracorporeal Membrane Oxygenation: A Focus on the Adjunctive Use of
Abstract:
Use of ketamine in patients requiring extracorporeal membrane oxygenation (ECMO) has rarely been reported, and the optimal dosing strategy remains unclear. A patient admitted with hypoxic respiratory failure required ECMO in addition to continuous infusion of low-dose ketamine following titration of opioid and sedative medications to high doses. After initiation of ketamine, infusion rates of opioids and/or sedatives were maintained or decreased. Recorded Richmond Agitation-Sedation Scale (RASS) scores were -4 to -5 and documented pain scores were 0. No adverse effects were reported while receiving low-dose ketamine. This case illustrates that use of low-dose ketamine infusion may be a useful adjunctive agent in patients receiving ECMO and high-dose opioid and sedative medications.
