Anti-factor Xa vs aPTT for heparin monitoring in extracorporeal membrane oxygenation.
Am J Health Syst Pharm

Article Synopsis
- - The study aimed to assess how anti-factor Xa (anti-Xa) and activated partial thromboplastin time (aPTT) correlate with heparin dosing in adult patients receiving ECMO treatment for at least 24 hours.
- - Researchers found a weak correlation between anti-Xa and aPTT measures based on data from 27 patients, with some hemorrhagic events linked to high aPTT levels but not to anti-Xa levels.
- - The conclusion highlighted that while hemorrhagic events were more frequent than thrombotic ones, no clear relationship was established between these events and the coagulation measures in patients, including those with COVID-19. Further research is needed for ECMO patients without COVID-19.*
