• Review History of Trauma Resuscitation
• Discuss Coagulopathies in Trauma
• Discuss Integrated Damage Control
• Review Blood Component Preparations
• Discuss Individual Component Transfusion
Guidelines
• Discuss Massive Transfusion Protocols
• Discuss Future Research Areas
• World War I
– Little or no systematic resuscitation after injury
– Blood banking developed
• World War II
– Widespread use of blood and albumin
– Long, slow evacuation
– Significant organ failure – renal, pulmonary
– Late deaths from sepsis
• Korean War
– Forward Surgical Care
– Rapid Care
– Evacuation to Definitive Treatment
– Blood and albumin as in WWII
• Vietnam War
– Rapid evacuation
– Large-volume resuscitation with blood/crystalloid
– Da Nang Lung (ALI/ARDS)
• Civilian Experience
– Trauma Registries and Research
– Empiric high-volume crystalloid resuscitation
– Iatrogenic Coagulopathy after Trauma recognized
– Directed Component Therapy
• Requires Laboratory evidence
• Empiric therapy limited
– Massive Transfusion Protocols
• Military Experience – Iraq and Afghanistan
• Limited Component availability
• Recognition of crystalloid inflammatory response
• Whole blood transfusion
• Walking Blood Bank
– Simple technology
– Screened donor population readily available
• Recognized in patients with significant tissue injury and hypotension
• Distinct from iatrogenic coagulopathy after trauma
– Dilutional coagulopathy
• Present prior to resuscitation in rapidly evacuated severe trauma
• Mortality rate increased 4x
• Modulated through protein C activation
• Damage Control Surgery
– Rapid, limited, forward surgical care
• Control bleeding
• Control spillage
• Control contamination
• Restore perfusion
– Avoid unnecessary interventions
– Allow for resuscitation
– Rapid evacuation
• Hemostatic Resuscitation
– Limited volume
– Permissive hypotension
– Balanced transfusion
• High FFP:PRBC ratio
– Colloid vs. crystalloid
– Attenuate ATC
– Expand resource availability
• Walking blood bank
• Freeze-dried plasma

Risk of transfusionassociated sepsis
• Advantages
– Wider use of limited resources
• 1 donated unit – multiple products
– Longer storage life
– Lower costs in elective use
– More predictable availability
• Disadvantages
– Multiple donor antigen exposure
– Less efficacy in high volumes, Lab costs
• Fresh Frozen Plasma
– Prothrombin Time (PT) > 17 sec
– Clotting Factor Deficiency (<25% of normal)
– Massive Transfusion (1 unit/5units RBCs) or clinically bleeding
– Severe Traumatic Brain Injury
• Cryoprecipitate
– Fibrinogen < 100mg/dL
– Hemophilia A, von Willebrand disease
– Severe Traumatic Brain Injury
• Platelets
– Platelet count < 10,000/uL
– Platelet count 10,000 to 20,000 with bleeding
– Platelet count < 50,000 after severe trauma
– Bleeding Time > 15 mins
– Platelet concentrates (5.5 x 10 10 in 50ml)
– Platelet apheresis (3 x 10 11 in 300ml)
• Packed Red Blood Cells (PRBCs)
– Hemoglobin < 7g/dL
– Acute blood volume loss > 15%
– > 20% decrease in BP, or BP <100mm Hg due to blood loss
– Hemoglobin < 10g/dL with significant cardiac disease or symptoms (chest pain, dyspnea, fatigue, orthostatic hypotension)
– Hemoglobin < 11g/dL in patient at risk for MOF
• Defined as > 10 units PRBCs within 24 hrs
• 25-30% of trauma patients requiring massive transfusion will present with Acute Traumatic
Coagulopathy (ATC)
– Penetrating mechanism
– Positive FAST
– Arrival SBP < 90mm Hg, HR > 120 bpm
– Unstable pelvic fracture
– pH < 7.25, base deficit
• Advantages
– More closely replicate whole blood physiology with components
– Retain shelf-life advantage of components
– 25-30% reduction in PRBCs used
– Predictable workload
• Disadvantages
– Processing time limitations
– Limited applicability

A massive transfusion protocol to decrease blood component use and costs, Arch Surg
143:686-691, 2008.
• Typically start with 2-6 units Type O blood
– Initial “emergency-release”
– Subsequent units type-specific, cross-matched
• FFP processing time
– ER prestaging thawed plasma, shelf-life 4-5 days
• Protocols can enhance effective use of staffing and resources
• Autotransfusion
– Limited applicability due to capture, possible contamination
• Blood salvage
– Intraoperative or postoperative
– Labor intensive, expensive, limited utility
• Autologous donation, Hemodilution not applicable to trauma setting
• Determine optimal therapeutic ratio of
PRBC:FFP
– PROPPR Study - 1:1:1 vs. 1:1:2 PRBC/PLT/FFP
• Further delineate ATC physiology and identify clinically useful modulators
• Delineate impact of high-ratio therapy on sub-
MT trauma population
• Blood component substitutes
• Crystalloid alternatives
