Effect of hypotensive resuscitation on survival rates
• Rationale
in trauma
patients
• Limitation
1. Penetrating
trauma – increase in survival rate.
2. Blunt trauma – no effect on survival rate.
Early prevention of hypothermia & acidosis
Conclusion: The prevention and timely correction, especially of
the combination acidosis plus hypothermia, is crucial for the
treatment of hemorrhagic coagulopathy.

I - Massive transfusion protocol
I - Massive transfusion protocol
Conclusion: We have demonstrated that an exsanguination
protocol, delivered in an aggressive and predefined manner,
significantly reduces mortality as well as overall blood product
consumption.
I - Massive transfusion protocol
Conclusion: MTP was associated with a reduction in multi-organ
failure and infectious complications, as well as an increase in
ventilator free days. In addition, implementation of MTP was
followed by a dramatic reduction in development of abdominal
compartment syndrome and the incidence of open abdomen.
II - Fresh whole blood transfusion
Conclusion: In patients with trauma with hemorrhagic shock,
resuscitation strategies that include WFWB may improve 30day survival, and may be a result of less anticoagulants and
additives with WFWB use in this population.
III - Optimum ratio of blood products
Conclusion: In the civilian setting, plasma, platelets, and
cryoprecipitate products significantly increased 30-day
survival in trauma patients.
III - Optimum ratio of blood products

Increased number of coagulation products
in relationship to red blood cell products
transfused improves mortality in trauma
patients.
Transfusion. 2010; 50(2): 493-500.
VI - POC coagulation assays:
role of thrombelastography
Conclusion: Thrombelastography was a more accurate indicator of
blood product requirements than PT, PTT, and INR. Thrombelastography enhanced by platelet count and hematocrit can guide
blood transfusion requirements.
V - Role of antifibrinolytic in patients with
hemorrhagic trauma
Lancet 2010; 376: 23–32
Conclusion: Early administration of tranexamic acid to
trauma patients with, or at risk of, significant bleeding
reduces the risk of death from hemorrhage with no
apparent increase in fatal or nonfatal vascular occlusive
events.
VI- Role of recombinant factor VIIa for
refractory traumatic hemorrhage
Conclusion: rFVIIa reduced blood product use but did not
affect mortality compared with placebo. Modern evidencebased trauma lowers mortality, paradoxically making
outcomes studies increasingly difficult.

VII - Role of vasopressin for hemorrhagic
trauma
World J Surg. 2011; 35(2): 430–439
Conclusion: Infusion of low-dose vasopressin could maintain
elevated serum vasopressin concentrations and decreased fluid
requirements after injury, and was associated with a possible early
survival advantage
