In this, our 50th episode, we are in Austin, TX, for the Annual EAST Scientific Meeting where we are joined by Dr. Bryan A. Cotton who shares his expertise and knowledge regarding the use of whole blood (WB) in trauma patients. From the use of whole blood in prior military conflicts to the design and successful implementation of one of the only prospective randomized controlled trials of modified whole blood use in trauma patients, Dr. Cotton provides an incredible overview of the potential benefits of whole blood or as he refers to it - "the dying blood product". Also covered in expert fashion are the role of other hemostatic products and strategies including tranexamic acid, fibrinogen concentrates, and a plasma first resuscitation strategy.
