Epidemiology of traumatic deaths: comprehensive population-based assessment World J Surg. 2010;34(1):158-63. Trauma associated coagulopathy: the old theory The lethal triadcircle The bloody vicious Acute coagulopathy of trauma: the new hypothesis Systemic anticoagulation Hyperfibrinolysis Endothelium express thrombomodulin TM complexes with Thrombin Activation of protein C pathway Endothelium releases tPA coagulopathy Hyper fibrinolysis Extrinsic Pathway is inhibited Systemic anticoagulation Fibrinogen depletion J R Army Med Corps. 2007; 153(4): 299-300. ‘Systematic approach to major trauma combining the catastrophic bleeding, airway, breathing and circulation (<C>ABC) paradigm with a series of clinical techniques from point of wounding to definitive treatment in order to minimize blood loss, maximize tissue oxygenation and optimize outcome’. Armamentarium of damage control resuscitation Permissive hypotension Early prevention of hypothermia, acidosis Rapid control of bleeding Hemostatic resuscitation Permissive hypotension Journal of the Intensive Care Society 2009; 10(2): 109-114 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. Rapid control of bleeding J R Army Med Corps. 2009; 155(4): 323-326. Damage control surgery Stage I — Rapid control of bleeding Stage II — Delayed surgical repair Hemostatic resuscitation Massive transfusion protocol Fresh whole blood transfusion Vasopressin Hemostatic resuscitation Optimum ratio of blood product Recombinant factor VIIa Antifibrinolytic POC coagulation assays 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 Shaz BH, Dente CJ, Nicholas J, MacLeod JB, Young AN, Easley K, Ling Q, Harris RS, Hillyer CD. 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.
