TXA combined with whole blood transfusion in trauma patients does not increase the risk of VTE but shock index does.

These data demonstrate that the combination of WB ​+ ​TXA administered to trauma patients has no higher risk of VTE than patients who receive PRBC ​+ ​TXA, a comparison that has not been studied clinically to date. Despite the pro thrombotic state enhanced by TXA and the decreased dilutional coagulopathy seen in WB resuscitation, there was no increased risk of VTE compared to TXA ​+ ​PRBC. There is no evidence that TXA combined with whole blood transfusion is associated with an increased risk of VTE. However, higher pre-hospital SI was associated with an elevated rate of VTE. These clinical features provide insight into patients who may be at an increased risk of developing VTE and may benefit from targeted prevention strategies.
