Activated Partial Thromboplastin Time and Anti-IIa Monitoring in Argatroban Anticoagulation in COVID-19 Patients on Venovenous Extracorporeal Membrane Oxygenation.

ABSTRACT: Unfractionated heparin has long been considered the standard anticoagulation in ECMO, despite some pitfalls such as heparin resistance, heparin induced thrombocytopenia (HIT), etc Recently, some centres started to increasingly use argatroban for this purpose, typically using activated partial thromboplastin time (aPTT) for its monitoring. Direct monitoring of the efficacy of argatroban using Anti-IIa is not yet an established method, although it might be more appropriate as it targets the same pathway.An observational study was performed in adult veno-venous ECMO patients hospitalized with SARS-CoV-2 infection anticoagulated with argatroban to an aPTT target of 40-60 s and Anti-IIa target of 0.4-0.6 µg/mL. Bleeding and thrombotic complications were monitored.Forty-four VV ECMO patients wer
