We have been using this for years in cardiac, chest, ortho and ENT surgery. Any surgery where there is a risk for bleeding or observed bleeding. TXA is an antifibrinolytic for what its worth. It works on the back end of the clotting cascade where fibrin is broken down and stabilizes the blood clot to prevent further bleeding.
I guess the medical value of this study was simply to give a final “thumbs-up” for its continued use with non-cardiac surgery, if it was a common practice, already.
