NCT04684719

Brief Summary

Open label, multi-center, pre-hospital randomized trial utilizing 10 level-1 trauma centers designed to determine the efficacy and safety of low titer whole blood resuscitation as compared to standard of care resuscitation in patients at risk of hemorrhagic shock and to appropriately characterize the hemostatic competency of whole blood relative to its age.
