Abstract:
The early administration of tranexamic acid is recognised as significantly reducing mortality in traumatically injured patients with major haemorrhage, typically given via intravenous or intramuscular routes. In the context of mass casualty events, there may exist multiple traumatically injured casualties that would benefit from tranexamic acid, however, it's administration may be delayed through the need to establish intravenous access. Additionally, if the initial assessment of the traumatically injured casualty is undertaken by an individual who cannot administer intravenous or intramuscular medications, time to administration will be further delayed. This concepts paper seeks to discuss the potential for utilising oral tranexamic acid, in the context of mass casualty events, as an alternative administration route.

Introduction to Hemostasis
The three phases of hemostasis involve many clotting factors present in plasma and several substances released by platelets and injured tissue cells. It is a fast, localized,...

Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...

Coagulation
During the coagulation phase, clotting factors, or procoagulants, play a vital role in initiating and progressing the coagulation cascade. This cascade is a series of reactions...
