5. Study Description

Brief Summary
The investigators present a randomised open label phase Ib/IIa trial of nebulised unfractionated heparin to evaluate the effect of nebulised unfractionated heparin on the procoagulant response in ICU patients with SARS-CoV-2 requiring advanced respiratory support. As this is one of the first studies of nebulised heparin in COVID 19 lung disease the investigators will assess safety as a co-primary outcome.
