Insert wide bore peripheral or central cannulae
Give pre-warmed crystalloid or colloid as needed, keep patient warm.
Avoid hypotension or urine output <0.5 ml/kg/h
Concealed blood loss is often underestimated
A named senior person must take responsibility for communication and documentation.

CBC, PT, APTT, Thrombin time,
Fibrinogen, DIC profile.
Blood gases and pulse oximetry
Ensure correct sample identification
Repeat tests after blood component infusion
Results may be affected by colloid infusion
May need to give components before results available
Assess degree of urgency
Employ blood salvage to minimize allogeneic blood use
Give red cells
Group O Rh D negative In extreme emergency Until ABO and Rh D groups known
Use blood warmer and/or rapid infusion device if flow rate >50 ml/kg/h in adult
Anticipate platelet count <50 after 2 blood volume replacement.
Maintain PT & APTT < 1.5 · mean control
Give FFP 12 –15 ml/kg guided by tests
Anticipate need for FFP after 1 –1.5 blood volume replacement
Allow for 30 min thawing time
Maintain Fibrinogen > 1.0 g/l
If not corrected by FFP give cryoprecipitate (Two packs of pooled cryoprecipitate for an adult)
Allow for 30 min thawing time
Keep ionised Ca2+ > 1Æ13 mmol/l
Multidisplinary services: Hospital
Transfusion Committee.
Improve awareness and confidence and ensure that the blood transfusion chain works efficiently.
Rapid communication cascade.
Safe and jusdicious use of blood components.
Prevents post massive transfusion coagulopathy.
Aims to reduce use of blood products in the intensive care phase.
With 5-7 unitis PRBC’s Plt count decreases to less than 50 %
With 5 units PRBC PT is increased to more than 1.5 control.
Erythrocytes promote marginalization of platelets so the platelet concentrates along the endothelium and remains almost seven times that of the average blood concentration
Erythrocytes support thrombin generation by activating platelets by liberating ADP.
Oxygenation delivery.
It remains controversial when and in what dose plasma should be transfused to massively bleeding trauma patients.
The optimal ratio of FFP to RBCs remains to be established: FFP:RBC ratio greater than 1:2 is associated with improved survival compared to one lower than 1:2.
Meta-analysis from 2010-2012: Patients undergoing massive transfusion, high FFP to RBC ratios was associated with a significant reduction in the risk of death
(odds ratio (OR) 0.38 (95%CI 0.24-0.60) and multiorgan failure (OR 0.40 (95%CI
0.26-0.60).

Borgman MA. et al. The ratio of blood products transfused affects mortality in patients receiving massive transfusions at a combat support hospital J trauma, 2007. 66:805-813
Platelets are also pivotal for hemostasis: low Plts increases mortality.
The highest survival was established in patients who received both a high
PLT:RBC and a high FFP:RBC ratio.

10 RBC, 4 FFP and 2 apheresis PLT for trauma patients.
211 trauma patients of who 94 received TEP and 117 were historic controls.
The TEP patients received more RBC (16 vs. 11), FFP (8 vs. 4), and PLT (2 vs. 1) intraoperatively than the controls.
The protocol group displayed lower 30-day mortality (51% vs. 66%).
After controlling for age, sex, mechanism of injury, Trauma and
Injury Severity Score (TRISS), and 24-hour blood product usage, a
74% reduction in the odds ratio of mortality was found among patients in the TEP group .

Routine use of fresh whole blood (FWB) for resuscitation of bleeding patients was abandoned in the civilian setting.
In the combat setting, however, FWB has been used.
In a report of US military patients in Iraq and Afghanistan from January 2004 to October 2007, those with hemorrhagic shock, a resuscitation strategy that included
FWB was associated with improved 30-day survival
(95% vs. 82%, p=0.002).

Immediate labs service is important to identify coagulopathy, and guide ongoing transfusion therapy.
Massive hemorrhage could results in serious life threatening complications
Massive bleeding and massive transfusion could lead to severe coagulaopthy which tight a viscous cycle that could cause mortality
While resuscitation your patient keep patient warm with normal calcium level
Identify and correct source of bleeding.
Implementation of a homeostatic control resuscitation strategy to massively bleeding patients seems both reasonable and lifesaving.
