Trauma Clinical Trial
Official title:
A Multi-centre, Prospective, Randomized Controlled Study to Compare Outcomes of Viscoelastic Haemostatic Assay (VHA)-Guided Resuscitation Versus Conventional Resuscitation Support in Haemorrhaging Trauma Patients
This trial compares the haemostatic effect of viscoelastic haemostatic assay (VHA)-guided transfusion strategy versus non-VHA guided transfusion strategy in haemorrhaging trauma patients. Half of the randomised patients will receive VHA-led management of bleeding, whilst the other half will receive massive transfusion protocol resuscitation using conventional coagulation tests.
Trauma is the most frequent cause of death in persons aged under 40, with half of these
deaths resulting from uncontrolled bleeding. 1 in 4 of all severely injured and shocked
patients develop a clotting abnormality termed Trauma Induced Coagulopathy (TIC) within
minutes of injury, which causes blood to continue being lost from the body faster than it can
be stemmed. Many more injured patients will go on to develop different types of coagulopathy
at different times during the course of their treatment, either as a result of their body's
ongoing response to trauma or as a consequence of their clinical care. Ultimately
coagulopathic patients have increased blood transfusion requirements and suffer more adverse
outcomes (e.g. multi organ failure).
Current management of coagulopathic, haemorrhaging trauma patients comprises the unguided
transfusion of large volumes of red blood cells and clotting product supplements. Without
rapidly available and validated diagnostics, products are delivered empirically to patients
blind to the type and severity of TIC they may have or indeed even if they do not have TIC.
This study will compare outcomes of viscoelastic haemostatic assay (VHA)-guided resuscitation
versus conventional management of critically bleeding trauma patients. The hypothesis is that
goal-directed haemostatic resuscitation of coagulopathic bleeding trauma patients will yield
improved outcomes and reduced blood product demand, compared to empiric massive transfusion
therapy.
