Trauma-induced coagulopathy (TIC) occurs early after severe injury. TIC is associated with a substantial increase in bleeding rate, transfusion requirements, and a 4-fold higher mortality. Rapid surgical control of blood loss and early aggressive hemostatic therapy are essential steps in improving survival. ⋯ The effect of prehospital fibrinogen concentrate administration on outcome in major trauma patients is the subject of an ongoing prospective investigation. The use of prothrombin complex concentrate is potentially helpful in patients anticoagulated with vitamin K antagonists who experience substantial trauma or traumatic brain injury. Beyond emergency reversal of vitamin K antagonists, safety data on prothrombin complex concentrate use in trauma are lacking.

This review is a synopsis of the decisions that shaped global policy on platelet (PLT) storage temperature and a focused appraisal of the literature on which those discussions were based. We hypothesize that choices were centered on optimization of preventive PLT transfusion strategies, possibly to the detriment of the therapeutic needs of acutely bleeding patients. Refrigerated PLTs are a better hemostatic product, and they are safer in that they are less prone to bacterial contamination. ⋯ Data from two randomized controlled trials bring into question the concept that stable autologous stem cell transplant patients with hypoproliferative thrombocytopenia should continue to receive prophylactic transfusions. At the same time, new findings regarding the efficacy of cold PLTs and their potential role in treating acute bleeding have revived the debate regarding optimal PLT storage temperature. In summary, a "one-size-fits-all" strategy for PLT storage may not be adequate, and a reexamination of whether cold-stored PLTs should be offered as a widely available therapeutic product may be indicated.

2013 RDCR Supplement: Role of Transfused Red Blood Cells for Shock and Coagulopathy within RDCR.
The philosophy of damage control resuscitation (DCR) and remote damage control resuscitation (RDCR) can be summarized by stating that the goal is to prevent death from hemorrhagic shock by "staying out of trouble instead of getting out of trouble." In other words, it is preferred to arrest the progression of shock, rather than also having to reverse this condition after significant tissue damage and organ injury cascades are established. Moreover, to prevent death from exsanguination, a balanced approach to the treatment of both shock and coagulopathy is required. This was military doctrine during World War II, but seemed to be forgotten during the last half of the 20th century. ⋯ Early reversal of shock is essential to prevent exacerbation of coagulopathy and progression of cell death cascades in patients with severe traumatic injuries. Red blood cell storage solutions have evolved to accommodate the needs of non-critically ill patients yet may not be optimal for patients in hemorrhagic shock. Continued focus on the recognition and treatment of shock is essential for continued improvement in outcomes for patients who require damage control resuscitation and RDCR.

The environmental and logistical constraints of the prehospital setting make it a challenging place for the treatment of trauma patients. This is perhaps more pronounced in the management of battlefield casualties before extraction to definitive care. In seeking solutions, interest has been renewed in implementing damage control resuscitation principles in the prehospital setting, a concept termed remote damage control resuscitation. ⋯ Management of trauma-related airway and respiratory compromise is evolving, with scope to improve on currently accepted practices. The purpose of this review is to highlight the challenges of treating patients in the prehospital setting and suggest potential solutions. In doing so, we hope to maintain the enthusiasm from people in the field and highlight areas for prehospital specific research and development, so that improved rates of casualty survival will continue.

Through necessity, military medicine has been the driver of medical innovation throughout history. The battlefield presents challenges, such as the requirement to provide care while under threat, resource limitation, and prolonged evacuation times, which must be overcome to improve casualty survival. Focus must also be placed on identifying the causes, and timing, of death within the battlefield. ⋯ We must also carry on working alongside our civilian colleagues so that the benefits of translational experience are not lost. This review describes several countries current military approaches to prehospital trauma care. These approaches, refined through a decade of experience, merit consideration for integration into civilian prehospital care practice.
