A systematic review on pharmacokinetic changes in critically ill patients: role of extracorporeal membrane oxygenation.
Year: 2011
Type: review
Study design: Systematic Review
Abstract: OBJECTIVE: Several factors including disease condition and different procedures could alter pharmacokinetic profile of drugs in critically ill patients. For optimizing patient's outcome, changing in dosing regimen is necessary. Extracorporeal Membrane Oxygenation (ECMO) is one of the procedures which could change pharmacokinetic parameters.The aim of this review was to evaluate the effect of ECMO support on pharmacokinetic parameters and subsequently pharmacotherapy. METHOD: A systematic review was conducted by reviewing all papers found by searching following key words; extracorporeal membrane oxygenation, ECMO, pharmacokinetic and pharmacotherapy in bibliography database. RESULTS: Different drug classes have been studied; mostly antibiotics. Almost all of the studies have been performed in neonates (as a case series). ECMO support is associated with altered pharmacokinetic parameters that may result in acute changes in plasma concentrations with potentially unpredictable pharmacological effect. Altreation in volume of distribution, protein binding, renal or hepatic clearance and sequestration of drugs by ECMO circuit may result in higher or lower doses requirement during ECMO. As yet, definite dosing guideline is not available. ECMO is extensively used recently for therapy and as a procedure affects pharmacokinetics profile along with other factors in critically ill patients. For optimizing the pharmacodynamic response and outcome of patients, drug regimen should be individualized through therapeutic drug monitoring whenever possible.
