Hemostasis in COVID-19: an Adaptive Clinical Trial
June 4, 2021 updated by: Vanderson Geraldo Rocha, University of Sao Paulo General Hospital
Dynamics of Hemostatic Parameters in COVID-19 and Comparison of Intervention Strategies Through Adaptive Clinical Trial
Hypercoagulability has been demonstrated in COVID-19, leading to respiratory distress and increased mortality.
This is an adaptive clinical trial to compare the efficacy and safety of two experimental strategies in patients with COVID-19: ASA or inhaled UFH associated with standard VTE prophylaxis.
