Acute Respiratory Failure, Anticoagulants, SARS CoV 2 Infection

Brief summary

Coronavirus Disease (COVID-19) is characterized by a hypercoagulable state, sometimes difficult to be managed with heparin. Bivalirudin, a member of the direct thrombin inhibitor drug class, offers potential advantages compared to heparin, including to its ability to exert its effect by directly attaching to and inhibiting freely circulating and fibrin-bound thrombin. Investigators have therefore designed this pilot open-label randomized controlled trial to assess if a off-label infusion of bivalirudin may reduce thrombosis, mortality, Intensive Care Unit (ICU) length of stay and increase ventilator free days of patients admitted in ICU for acute respiratory failure due to COVID-19, as compared to first-line treatment with heparin.

Interventions

DRUGEnoxaparin Sodium

Enoxaparin will be subcutaneously administered at a dosage from 4000 to 8000 twice daily according

DRUGBivalirudin

Bivalirudin will be intravenously administered to obtain an activated prothrombin time (aPTT) of 1.5 fold of the normal values.
