Optimizing pharmacotherapy regimens in adult patients receiving extracorporeal membrane oxygenation: A narrative review for clinical pharmacists

Extracorporeal membrane oxygenation (ECMO) is a complex therapy aimed at providing mechanical support for patients with severe, life-threating cardiac and/or respiratory failure. Research has demonstrated variability in pharmacokinetic changes in the critically ill patient population receiving ECMO. There is a need to understand the complexity of these pharmacokinetic changes to provide optimal pharmacotherapeutic regimens thereby maximizing effectiveness and mitigating harm. However, the number of pharmacokinetic studies in patients receiving ECMO remains small, and very few prospective studies have been published addressing optimal analgesic, sedative, or antimicrobial therapy. Anticoagulation is an additional important component of ECMO therapy but the preferred agent as well as dosing and monitoring strategy are unclear. The purpose of this narrative review is to discuss analgesia and sedation, antimicrobial, and anticoagulation management strategies in adult patients receiving ECMO.
