Geir Strandenes' talk at The Bick Sick in Zermatt, 2018.
Geir does a tour de force on blood transfusion, its history, physiology, the evidence base and ongoing developments in prehospital transfusion practice in both civilian and military settings. He specifically adresses how to apply principles of damage control resuscitation to remote locations and the introduction of fresh whole blood prehospitally from the point of injury onward.
Geir represents the THOR network (Trauma Hemostasis and Oxygenation Research network) where you can find more information

“There are three stages of scientific discovery: first
people deny it is true; then they deny it is
important; finally they credit the wrong person.’’

7. GOAL : Improve survival of patients with life
threatening bleeding : focus on the
presurgical phase of care
10. THOR- Trauma Hemostasis & Oxygenation
Research Network
An international multidisciplinary network of
civilian and military providers ranging from
first responders and medics to critical care
physicians and from basic scientists to
clinical trialists.
11. Advocates for:
• FWB or CWB as the optimal prehospital choice for hem. shock
• TXA as an adjunct to whole blood
• Balanced blood components if FWB not feasible

15. Fluid Resuscitation from
Hemorrhagic Shock: 2014
“The historic role of crystalloid and colloid solutions in
trauma resuscitation represents the triumph of hope
and wishful thinking over physiology and experience.”
LTC Andre Cap
J Trauma, 2015
There is an increasing awareness that fluid resuscitation
for casualties in hemorrhagic shock is best
accomplished with fluid that is identical to that lost by
the casualty - whole blood.
16. «The transfusion of whole blood – A suggestion for
its more frequent employment in war surgery»
«But the addition of salt solution to the circulation is
at best only a temporary measure, and merely
makes up for the loss of fluid, which is only one
factor in the condition»
«The broad indications for blood transfusion are
based on the fact that transfused blood is the best
substitute for blood lost (…) In certain haemorrhages
it has definitive haemostatic properties (…)
22. HISTORICAL CHANGE IN APPROACH
• WHOLE BLOOD INTRODUCED AS FLUID OF CHOICE WW1 –
NO RANDOMISED CONTROL TRIAL(RCT)
• PENICILLIN SAVED THOUSANDS OF LIFES DURING WW2 –
NO RCT
• FREEZE DRIED PLASMA INTRODUCED WW2 – 10 MILLION
UNITS USED – NO RCT
• COMPONENTS INTRODUSED – NO RCT
• CRYSTALLOIDS INTRODUCED – NO RCT
• BLOOD REINTRODUCED – NO RCT
23. HISTORICAL CHANGE IN APPROACH
• MURPHY AND GARDNER CHANGED PLATELET TRANSFUSION
STRATEGY BASED ON IN VITRO STUDIES AND IN VIVO
RECOVERY AND SURVIVAL DATA
• COLD STORED PLATELETS HAVE BETTER PRESERVED
MITOCHONDRIAL RESPIRATION AND AGGREGATION
• WE STILL USE RT STORED PLT FOR BLEEDING
• ONE RANDOMISED CONTROLED CLINICAL TRIAL

28. Guidelines
Civilian guidelines
• Use of isotonic crystalloid solutions should be
initiated in the hypotensive bleeding trauma
patient.
• RBC treatment should aim to achieve a target
Hb of 7-9 g/dl
• Initial management of patients with expected
massive haemorrhage should include plasma in a
plasma- RBC ratio of at least 1:2 as needed or
fibrinogen concentrate and RBC according to Hb
level.
• Platelets should be administered to
maintain a platelet count >50 109/l. A
platelet count >100 109/l in patients with ongoing
bleeding and/or TBI may be maintained.
• If a concentrate-based strategy is used, fibrinogen
concentrate or cryoprecipitate should be
administered if significant bleeding is accompanied
by viscoelastic signs of a functional fibrinogen
deficit or a plasma fibrinogen level of less than 1.5-
2.0 g/l.
Military guidelines (TCCC)
1) Whole Blood (Hb 12-13G/DL)
2) Plasma RBC’s Platelets (1 : 1 : 1) (Hb 9,0 gr/dl)
3) Plasma RBC’s (1 : 1)
4) Plasma or RBC’s alone
5) Colloids and crystalloids only if above is not
available
31. + Damage Control
Damage Control:
First, only do the things
essential to keeping the ship
afloat.
Rotondo MF, Schwab CW, et al. J Trauma. 1993;35(3):375-82.
32. + Resuscitation
Emergency treatment to restore:
Circulating volume
Aid oxygen delivery
Replace hemostatic potential
(and a few
other things…)
33. RDCR-WHAT ARE WE AIMING FOR??
• Maintain Oxygen Delivery(D02) above the threshold for delivery
dependent oxygen consumption(V02)
• Maintain/Support hemostasis to reduce the “Blood Leak”
• No shock – no coagulopathy!
• Prevent shock or treat shock??

Understand shock,
endotheliopathy, and coagulopathy not
as isolated events, but rather as the
result of changes
taking place within a single dynamic
organ system

the same coin (blood failure)
Blood loss → hypoxia
Hypoxia → fibrinolysis/coagulopathy

64. Norway: Whole Blood from 2013
Whole blood donor program: pre-deployment TTD testing, anti-A/anti-B titers,
universal donor identification.
Transfusion plan: Group A to A, O/low titer to all others.
Frigate has constant store 4 U WB O/low titer stored at 4°C, 14 days (tested,
Gulf of Aden 2013).
Norwegian Navy SOF currently carry GHB with stored WB on each mission.
65. NEW CPG FOR THE NORWEGIAN
ARMED FORCES 01.07.2017
• WHOLE BLOOD GROUP 0 LOW TITER AS THE
PREFERED RESUSCITATION FLUID FOR TRAUMATIC
HEMORRHAGIC SHOCK
• FROM POINT OF INJURY TO ROLE 2
• THE ENTIRE FORCE (NOT SOF ONLY)
69. Need Optimal Resuscitative Product
for Trauma-Induced Blood Failure
Mortality is high
Children - higher
Mortality occurs fast
Prehospital deaths occur commonly
High rate of preventable deaths from
hemorrhage
70. Whole Blood
FDA approved
CE Mark
Stored for up to 35 days
2-6 degrees C
450-500 ml per unit
Low titer group O WB
Optimal product for Trauma Induced
Blood Failure
71. Warm vs Cold Whole Blood
• Warm Fresh Whole Blood
– Collected then immediately transfused
– 8 hrs at room temp
• Cold Whole Blood
– Collected
– Tested
– Stored at 4C for up to 35 days
• Preferable 14-21 days
– Low titer group O preferred over ABO specific
72. Perceived Barriers to
Whole Blood
Must be ABO specific
Cannot leukoreduce without losing platelets
Cold platelets are not “functional”
73. Whole Blood Barriers -Disappeared
Low Titer Group O whole blood now standard product
Low titer definition
Range <200-256 for IgM 1
Platelet sparing filters since 2006
Cold platelets have superior hemostatic function
1 Belin TR, et al. J Trauma. 2017
74. Low titer group O whole blood
change in standards
New AABB standards for 2018
5.15 Selection of Compatible Blood and Blood Components
for Transfusion
5.15.1 Recipients shall receive ABO group-compatible Red Blood Cell
components, ABO group-specific Whole Blood, or low titer group O
Whole Blood (for non group O or for recipients whose ABO group is
unknown).
5.27 Urgent Requirement for Blood and Blood Components
5.27.1.1 If low titer group O Whole Blood is used, the BB/TS shall
define low titer group O Whole Blood and shall have policies,
processes and procedures for:
The use of low titer group O Whole Blood.
The maximum volume/units allowed per event.
Patient monitoring for adverse effects.
75. Resuscitation Paradigm
Early
Whole blood to immediately address TIBF
Soon thereafter
Goal Directed Hemostatic Resuscitation
Address global or specific deficits
Whole blood
Components
Antifibrinolytics
Factor concentrates

78. TO SUM UP – THE WHOLE IS GREATER THAN
THE SUM OF ITS PARTS
Shock and Its Magnitude (oxygen debt) is the main driver of Blood Failure
The Main Thing is to Keep the Main Thing the Main Thing(K.WARD)
• Hb matters in low flow state
• Hb matters for plt adhesion
• Reverse shock as early as possible to reduce shock dose
• Permissive hypotension with syst 80-90 over time might NOT be sufficient as endpoint for shock
reversal.
• Early platelet transfusion to mitigate plt dysfunction/loss/consumption
• Glycocalyx repair with plasma
• Holistic view of shock resuscitation to gain all of the above
