Recursive Partitioning Identifies Greater Than 4 Units of PRBCs Per Hour as an Improved Massive Transfusion Definition

摘要

BackgroundMassive transfusion (MT) is classically defined as >10units of packed RBCs in 24 hours. This fails to capture the most severely injured patients. Extending the prior work of Savage and Rahbar, a rolling hourly rate-based definition of MT may more accurately define critically injured patients requiring early, aggressive resuscitation.
