Early and Empirical High-Dose Cryoprecipitate for Hemorrhage After Traumatic Injury: The CRYOSTAT-2 Randomized Clinical Trial.
Summary
The purpose of this trial is to compare standard of care (SOC) massive transfusion protocol to SOC massive transfusion protocol plus early use of cryoprecipitate (within 90 minutes of emergency department arrival).
