Abstract

© The Author(s) 2019. Introduction: New antibiotics with bactericidal activity against multi-drug-resistant bacteria are increasingly used in the intensive care units. Here, we aimed to evaluate the influence of the extracorporeal membrane oxygenation on plasma levels of ceftolozane. Case report: A 34-year-old female was admitted to the intensive care unit after bilateral lung transplantation, complicated by primary graft dysfunction and cardiogenic shock needing venoarterial extracorporeal membrane oxygenation. Ceftolozane/tazobactam was started. Plasma ceftolozane levels were monitored on the first and third days of antibiotic treatment. A non-compartment pharmacokinetic analysis was performed and the extraction rate through the oxygenator was calculated. Discussion: The extracorporeal circuit of extracorporeal membrane oxygenation may alter the pharmacokinetics of antibiotics, to varying degrees due to drug sequestration and increased distribution volume. In this case, the extracorporeal membrane oxygenation circuit had little impact on the ceftolozane plasma concentration. Conclusion: Plasma levels of ceftolozane are stable in the extracorporeal membrane oxygenation circuit, suggesting that adjustment of standard doses of ceftolozane in patients with extracorporeal membrane oxygenation support may not be needed.
