• Common following traumatic injury caused by heat loss at the scene of injury and therapeutic treatments.

• Hypothermic patients (<35 °C) have significantly higher mortality than patients with the same severity of injury who remain NT.

• Coagulation protease activity is significantly affected below 33 °C

• Controlling for injury severity, it is an independent predictor of mortality

Page 17: Transfusion Strategies in a Trauma Patient · Learning Objectives • Enumerate various components of massive transfusion guidelines • List the recent updates in transfusion strategies

Trauma Induced Coagulopathy and Acute Coagulopathy of Trauma-Shock

• Trauma induced coagulopathy is an independent predictor of massive transfusion and death

• Coagulopathy increases mortality, transfusion requirements, multi organ failure, sepsis, and increased length of critical care stays

Acute traumatic coagulopathy (ATC),

• Between 24-56% of critically injured patients are affected

• Pathophysiology is not fully understood, tissue trauma and systemic hypoperfusion appear to be the primary factors

• DCR attempts to minimize iatrogenic resuscitation injury and the effects of traumatic shock through the management principals of – Permissive hypotension – Hemostatic resuscitation – Damage control surgery

Page 21: Transfusion Strategies in a Trauma Patient · Learning Objectives • Enumerate various components of massive transfusion guidelines • List the recent updates in transfusion strategies

Permissive hypotension

• Targets a lower than normal blood pressure to promote thrombus formation until surgical hemostasis can be achieved

• Minimizes initial volume of fluid to reduce systolic blood pressure while decreasing dilutional coagulopathy and hypothermia associated with aggressive fluid resuscitation

Jansen, J.O., et al., Damage control resuscitation for patients with major trauma. BMJ, 2009. 338: p. b1778. Holcomb, J.B., et al., Damage control resuscitation: directly addressing the early coagulopathy of trauma. J Trauma, 2007. 62(2): p. 307-10

Page 22: Transfusion Strategies in a Trauma Patient · Learning Objectives • Enumerate various components of massive transfusion guidelines • List the recent updates in transfusion strategies

Permissive Hypotension

• Rat model suggested that a target MAP of 50–60 mmHg conferred survival benefit in animals with uncontrolled hemorrhagic shock max tolerance limit of 90 min

• Morrison 2011 RCT prelim data

– LMAP- pts received significantly fewer blood products, smaller volumes of fluids intra-operatively, were less likely to develop post-operative coagulopathy and had a significantly lower mortality (p = 0.03)

• Describes a unified transfusion approach to severe hemorrhagic shock

• Begins immediately after the field assessment and is continued through the OR and into ICU

• Minimizes dilutional coagulopathy by replacing lost blood with plasma and platelet containing products

Does DCR work?

Cotton et al. published a large series investigating the efficacy of the 3 components of DCR in the civilian setting • Reduction in crystalloid and overall blood

product administration • Reduction in assoc. inflammatory mediators

of shock. • Associated with a 2.5-fold increased in 30 day

survival Cotton, B.A., et al., Damage control hematology: the impact of a trauma exsanguination protocol on survival and blood product utilization. J Trauma, 2008. 64(5): p. 1177-82; discussion 1182-3

Page 26: Transfusion Strategies in a Trauma Patient · Learning Objectives • Enumerate various components of massive transfusion guidelines • List the recent updates in transfusion strategies

Substantial Bleeding Protocols

(SBP) were developed to preemptively mitigate the lethal triad of acidosis, hypothermia, and coagulopathy through damage control resuscitation principles

Purpose and Creation • A SBP

Addresses the organizational issues necessary to respond to massive blood loss in an immediate and sustained manner. It reduces provider variability, facilitates staff communication and compliance, and simplifies the administration of predefined ratios of blood components.

Nunez, T.C., et al., Creation, implementation, and maturation of a massive transfusion protocol for the exsanguinating trauma patient. J Trauma, 2010. 68(6): p. 1498-505 Cotton, B.A., et al., Damage control hematology: the impact of a trauma exsanguination protocol on survival and blood product utilization. J Trauma, 2008. 64(5): p. 1177-82; discussion 1182-3

Page 28: Transfusion Strategies in a Trauma Patient · Learning Objectives • Enumerate various components of massive transfusion guidelines • List the recent updates in transfusion strategies

Implementation of a SBP protocol

• Requires the multidisciplinary participation of specialist from emergency medicine, surgeons, anesthesiologists, critical care, transfusion medicine, nurses, pathology and blood bank personnel

• The logistical complexity of such an extensive

collaboration makes the implementation of MT programs inconsistent, even in Level I trauma centers

Cotton, B.A., et al., Damage control hematology: the impact of a trauma exsanguination protocol on survival and blood product utilization. J Trauma, 2008. 64(5): p. 1177-82; discussion 1182-3

Activation

Image: http://ljsilentg.com/wp-content/uploads/2013/02/Start-finish-line.jpeg

• Attending surgeon (at our institution) activates SBP based on available clinical data

• Basic data is sent to Blood Bank including trauma “code” name, est. age, gender and resuscitation location.

• Type and screen is sent from the ED to the BB to convert released components over to type-specific products as soon as possible

Page 30: Transfusion Strategies in a Trauma Patient · Learning Objectives • Enumerate various components of massive transfusion guidelines • List the recent updates in transfusion strategies

Activation of…

• SBP activates the release of a cooler with 6 units of universal donor plasma and 6 units of uncrossmatched PRBC.

• Rapid release of these products is possible by

keeping several units (4–6) of thawed universal donor (AB) plasma on hand at all times.

• Additionally, 1 units of apheresis platelets is released with the cooler

Page 31: Transfusion Strategies in a Trauma Patient · Learning Objectives • Enumerate various components of massive transfusion guidelines • List the recent updates in transfusion strategies

SBP Benefits

• 2005, Cotton et al. evaluated the implementation of a SBP. – Fixed component transfusion protocol reduced the

odds of mortality by 74%. – Decreased 30 day mortality (51% vs. 66%, p = 0.03) – Increased the percentage of unexpected survivors,

and reduced unexpected deaths (22% vs. 5% and 9% vs. 22%, respectively; p< 0.05)

Cotton, B.A., et al., Damage control hematology: the impact of a trauma exsanguination protocol on survival and blood product utilization. J Trauma, 2008. 64(5): p. 1177-82; discussion 1182-3

Page 32: Transfusion Strategies in a Trauma Patient · Learning Objectives • Enumerate various components of massive transfusion guidelines • List the recent updates in transfusion strategies

How is this benefit realized?

O'Keeffe, T., et al., A massive transfusion protocol to decrease blood component use and costs. Arch Surg, 2008. 143(7): p. 686-90;

discussion 690-1.

• SBP’s shorten the initial time for first product delivery and improves efficiency of delivery for future cycles of blood products

Page 33: Transfusion Strategies in a Trauma Patient · Learning Objectives • Enumerate various components of massive transfusion guidelines • List the recent updates in transfusion strategies

• Early transfusion of increased ratios of plasma and platelets – Riskin et al., found survivor benefit (reduction from

45% to 19% morality p = 0.02) with reduced time to first product in SBP patients, with comparable 24 hour ratios of FFP to PRBCs

– SBP reduced time to first documented transfusion for

cross-matched PRBCs, FFP, and platelets by 39%, 33%, and 42%, respectively

O'Keeffe, T., et al., A massive transfusion protocol to decrease blood component use and costs. Arch Surg, 2008. 143(7): p. 686-90; discussion 690-1.

• Stanford University Medical Center protocol reduced time to first documented transfusion for cross-matched PRBCs, FFP, and platelets by 39%, 33%, and 42%, respectively

• Likewise, at Parkland Hospital

in Dallas, a delivery time of less than 10 minutes was achieved for the first cooler and subsequent cycles intervals were reduced from 42 to 18 minutes

Page 35: Transfusion Strategies in a Trauma Patient · Learning Objectives • Enumerate various components of massive transfusion guidelines • List the recent updates in transfusion strategies

• The benefit of MT protocol has been attributed to early transfusion of increased ratios of plasma and platelets

• Evidence suggests that outcomes are closely linked to a

reduced time between components, with ratios at 6 hours being more predictive of improved outcomes than ratios at 24 hours

While the importance of timing in multi-component transfusion is clear, the optimum ratios of components are less defined….

Page 37: Transfusion Strategies in a Trauma Patient · Learning Objectives • Enumerate various components of massive transfusion guidelines • List the recent updates in transfusion strategies

Blood Component Ratios

• WWI beginning of Vietnam, whole blood (WB) preferred product for resuscitation of hemorrhage

• Advances in component separation

1960-70s led to blood centers providing components (RBC, plasma, platelets) and removed whole blood from supply

Cannon WB et al, JAMA 1918 Kauvar DS et al. J Trauma 2006 and Strandenes G et al. Transfusion 2013 Spinella, P.C. and J.B. Holcomb, Resuscitation and transfusion principles for traumatic hemorrhagic shock. Blood Rev, 2009. 23(6): p. 231-40.

Page 38: Transfusion Strategies in a Trauma Patient · Learning Objectives • Enumerate various components of massive transfusion guidelines • List the recent updates in transfusion strategies

Blood Component Ratios

• One of the central tenets of hemostatic resuscitation is the delivery of fresh frozen plasma (FFP), platelets and red blood cells (RBC) in a ratio approaching 1:1:1

Page 39: Transfusion Strategies in a Trauma Patient · Learning Objectives • Enumerate various components of massive transfusion guidelines • List the recent updates in transfusion strategies

Dilution and storage loss reduce the effectiveness of component blood product therapy compared with fresh whole blood.

What is the best ratio?

• Murad et al. pooled analysis of four studies and showed that FFP:RBC ratios of greater than 1:3 are associated with a significant reduction in mortality (OR 0.38; 95% CI 0.24–0.60)

• Teixeira et al. and Zink et al. also found increase FFP: PRBC ratios were an independent predictor of survival

• Gunter et al. showed that 30 day mortality was

significantly decreased (41% versus 62%) with higher ratios of FFP and PLT to PRBC

Page 41: Transfusion Strategies in a Trauma Patient · Learning Objectives • Enumerate various components of massive transfusion guidelines • List the recent updates in transfusion strategies

Survivor Bias

• “In trauma resuscitation research, the conundrum of reverse causation is whether treatment caused patients to survive longer or patients received treatment only because they survived long enough.”

• The most important source of bias comes from the impact of survival

because patients who survive are more likely to receive FFP than patients who die, creating an artifactual association of survival with higher P:E ratios.

Page 42: Transfusion Strategies in a Trauma Patient · Learning Objectives • Enumerate various components of massive transfusion guidelines • List the recent updates in transfusion strategies

• Ho et al. examined 26 studies investigating blood product ratios and survivor bias.

– Fifteen of the 26 reviewed studies were determined to

be survivor bias unlikely – 10 of these 15 studies support improved survival

outcome with higher FFP:RBC ratios

Ho, A.M., et al., Prevalence of survivor bias in observational studies on fresh frozen plasma:erythrocyte ratios in trauma requiring massive transfusion. Anesthesiology, 2012. 116(3): p. 716-28.

Page 43: Transfusion Strategies in a Trauma Patient · Learning Objectives • Enumerate various components of massive transfusion guidelines • List the recent updates in transfusion strategies

PROMMTT study

• 10 center observation trial highlighted the variable nature of infusion, the importance of time, and improved outcomes with higher product ratios (n = 905, the analysis group).

• Primary outcome of interest was in-hospital mortality with a primary independent variables single plasma:RBC and platelet:RBC transfusion ratios

Holcomb, J.B., et al., The Prospective, Observational, Multicenter, Major Trauma Transfusion (PROMMTT) Study: Comparative Effectiveness of a Time-Varying Treatment With Competing Risks. Arch Surg, 2012: p. 1-10.

Page 44: Transfusion Strategies in a Trauma Patient · Learning Objectives • Enumerate various components of massive transfusion guidelines • List the recent updates in transfusion strategies

PROMMTT • In the first 6 hours, patients with ratios less than 1:2

were 3 to 4 times more likely to die than patients with ratios of 1:1 or higher.

• In pts receiving at least 3 units protective association between higher transfusion ratios and in-hospital mortality appears strongest within 6 hours and diminishes over time

• Mortality shifts from exsanguination to head injury, respiratory distress, organ failure, and infection after the first 24 hours.

So where are we now?

• Two studies are currently underway to address the questions of time to transfusion and optimal ratio of product delivery.

• A European trial, the Activation of Coagulation and Inflammation in Trauma (ACIT), aims to characterize temporal effects of coagulation and inflammation

• The Pragmatic Randomized Optimal Platelet and Plasma Ratios (PROPPR) study designed to definitely evaluate the benefit of blood product ratios on outcome.

Page 46: Transfusion Strategies in a Trauma Patient · Learning Objectives • Enumerate various components of massive transfusion guidelines • List the recent updates in transfusion strategies

Importance of PROPPR

• Provide valid, clinical trial framework for in-hospital trauma

• Address survival bias, primary critique of prior

retrospective studies • Understand mechanisms of trauma induced coagulation

(TIC) and inflammation – will be 1st to characterize natural history of coagulopathy and inflammation.

PROPPR

• Houston enrolled one patient every 3 days. • In the first 24 hours, following patients in the hospital

for up to 30 days, and getting 30 day vital status, 2000 data points were collected on each patient

• Average # of transfusion during initial resuscitation is 12 units RBCs randomized to 1:1:1 or 1:1:2 with 18-26 units of total blood products transfused during the initial resuscitation.

Page 50: Transfusion Strategies in a Trauma Patient · Learning Objectives • Enumerate various components of massive transfusion guidelines • List the recent updates in transfusion strategies

Tranexamic acid (TXA)

• CRASH-2 study, examined the effect of (TXA) on mortality and transfusion requirements in 20,000 adult patients with traumatic injury and hemorrhagic shock

• Mortality and mortality from bleeding were improved

following TXA administration (RR = 0.91; 95% CI 0.85–0.97) and (RR = 0.85; 95% CI 0.76–0.96), respectively

• Benefit of TXA was observed only when administration

within the first 3 h of injury

• Similar benefit was present in the combat injured.

• Despite being more severely

injured, the TXA group had lower unadjusted mortality than the no-TXA group (17.4% vs 23.9%, respectively; P=.03),

• Independently associated with survival (odds ratio=7.228; 95% CI, 3.016-17.322) and less coagulopathy (P=.003)

rFVIIa

• Two RCTs have shown a reduction in transfused pRBC following rFVIIa administration in blunt trauma although an improvement in mortality was not observed

• Systematic reviews of rFVIIa do not support rFVIIa as standard treatment for traumatic bleeding and should be considered in the management of refractory life-threatening hemorrhage, primarily in blunt trauma, when all conventional measures to control bleeding have failed

Prothrombin Complex Concentrates

• PCC pooled human plasma and contain 4 vitamin K dependent factors II, VII, IX, and X – 3 factor combo without F VII most commonly available

in the US • Effective alternative to FFP and rFVIIa for rapid

reversal of Coumadin therapy • Off label uses include coagulopathy due to

PCC in Trauma

• Animal models have shown an emerging role for PCC in traumatic hemorrhage. – 4-factor PCC reversed PT, improved thrombin generation,

shortened time to hemostasis, and reduced volume of blood loss compared to FFP

– In trauma patients with intracranial hemorrhage and elevated INR who were receiving oral VKAs, the use of a 4-factor PCC protocol resulted in improved times to normalization of INR, reversal of coagulopathy, and decreased time to operative intervention vs. FFP alone

• Advantages low volume vs FFP and avoids the necessity of thawing product, citrate toxicity, TRALI, and ABO group specificity

Fibrinogen concentrate

• Schochl et al. described use of fibrinogen concentrates and decreased the need for pRBC transfusion (29% vs. 3% in FFP control (P< 0.001) and platelet concentrate utilization (91% of vs. 56% in FFP control)

• Multi organ failure was significantly decreased in patients exclusively treated with coagulation factor concentrates

• Benefit of fibrinogen concentrate on mortality have been mixed

Survey results…

• 70% used a 1:1 ratio of pRBC/plasma for the initial resuscitation cycle, with some institutions altering ratios from cycle to cycle.

• Thawed plasma was available in only 60% of the responding hospitals for at least a portion of the first cycle, potentially delaying early administration.

• The routine use of cryoprecipitate and rVIIa as an adjunct therapy occurred in 36% and 15 % of protocols, respectively

Damage control resuscitation principles.

• Early transfusion of red blood cells:plasma:platelets in a 1:1:1 unit ratio

• Use of thawed plasma and fresh whole blood when available

• Appropriate use of coagulation factor products (rFVIIa) and fibrinogen containing products (fibrinogen concentrates, cryoprecipitate)

• Use of fresh RBCs (storage age of <14 days) • When available thromboelastography to direct blood

product and the hemostatic adjunct (anti-fibrinolytics and coagulation factor) administration

Conclusions/Summary

• While prospective randomized data are not currently available to guide many of these current practices, it must be recognized that the preponderance of data suggests that a balanced approach to plasma, platelets and RBCs, implemented early will improve outcome.
