Brief Summary
Bleeding is the most avoidable cause of death in trauma patients. Up to one-third of severely injured trauma patients are found to be coagulopathic and forty percent of the mortality following severe injury is due to uncontrollable hemorrhage in the setting of coagulopathy. It has been established that early administration of fresh frozen plasma decreases mortality following severe injury, replacing lost coagulation factors, improving the coagulopathy and restoring blood volume. This study will determine if giving plasma to severely injured trauma patients during ambulance transport versus after arrival to the hospital will help reduce hemorrhage, thus decreasing both total blood product administration and mortality.

Outcome Measures
Primary Outcomes (1)
Number of Participants That Died Within 28 Days Post Injury
death within 28 days post injury (death of any cause except for death due to a second, clearly unrelated traumatic injury suffered after discharge)

Composite Outcome of 28-day In-hospital Mortality and Postinjury Multiple Organ Failure (MOF) Incidence
28 days
Admission Coagulopathy
within 30 minutes of Emergency Department (ED) arrival
Number of Participants With Admission Severe Coagulopathy
within 30 minutes of Emergency Department (ED) arrival
Admission Clot Strength
within 30 minutes of ED arrival
Admission Acidosis

Number of Participants With Abnormal Baseline (Field) Coagulation Factor XIII Level
after injury prior to hospital arrival
Admission (First Arrival) Coagulation Factor Levels
after injury prior to hospital arrival
- +19 more other outcomes
Study Arms (2)
Plasma
EXPERIMENTALIf the patient is randomized to experimental arm, 2 units of frozen type AB plasma (FP24) will be thawed in the Plasmatherm Dry Thawing and Warming Device according to the operator manual as approved by the FDA in the ambulance and infusion will commence as soon as the type AB plasma is ready, and will continue during transport to the emergency department (ED). After infusion of 2 units of type AB plasma is completed, subsequent care will proceed per institutional, Advanced Trauma Life Support (ATLS) guided resuscitation with acute packed red blood cells (pRBC) administration determined by the hemodynamic response and additional blood component administration guided by rapid thrombelastography (rTEG) and coagulation panel assessment in conjunction with clinical scenario.
Standard
ACTIVE COMPARATORIf the patient is randomized to the standard arm, the patient will be given intravenous crystalloid fluid (normal saline) as the initial resuscitation fluid with 2 large bore IVs based on the current ATLS guidelines, the standard of care. Subsequent care will proceed per institutional, ATLS guided resuscitation with acute packed red blood cells pRBC administration determined by the hemodynamic response and additional blood component administration guided by rTEG and coagulation panel assessment in conjunction with clinical scenario.
Interventions
The plasma is thawed and administered to subjects in the experimental (plasma) arm.
Normal saline will be give to subjects in the standard arm as the current standard of care for an initial resuscitation fluid
