Despite the tremendous advances and successes in the care of combat casualties over the past 15 years of war, noncompressible torso hemorrhage (NCTH) remains the most likely source of potentially preventable death (approx. 25%) on the battlefield. This is also likely true for civilian victims of blunt and penetrating trauma. Various devices and therapeutic interventions have been, and are being, developed in an attempt to reduce morbidity and mortality for patients with NCTH. ⋯ Although each of these modalities offer the potential to staunch uncontrolled hemorrhage until an injured patient is able to reach definitive surgical care, further research and advances must be made to further reduce trauma morbidity and mortality and to identify those technologies and modalities that are best suited to rapid movement to the front lines of combat casualty care as well as to emergency medical personnel dealing with civilian trauma victims. The surgical adjuncts for NCTH discussed may all be considered as potential tools for patient blood management programs. If effective they offer the possibility of reduce hemorrhage and blood product exposure and improved patient outcomes.

The concept of remote damage control resuscitation (RDCR) is still in its infancy and there is significant work to be done to improve outcomes for patients with life-threatening bleeding secondary to injury. The prehospital phase of resuscitation is critical and if shock and coagulopathy can be rapidly minimized before hospital admission this will very likely reduce morbidity and mortality. The optimum transfusion strategy for these patients is still highly debated and the potential implications of the recently published pragmatic, randomize, optimal platelet, and plasma ratios trial (PROPPR) for RDCR have been reviewed. ⋯ Handheld point-of-care devices may be able to support and guide the prehospital and remote use of intravenous hemostatic agents including coagulation factor concentrates along with clinical presentation, assessment, and the extent of bleeding. Combinations may even be more effective for bleeding control. More studies are urgently needed.

Implications from the pragmatic, randomize, optimal platelet and plasma ratios (PROPPR) trial are critical for remote damage control resuscitation (DCR). Utilizing DCR principals in remote settings can combat early mortality from hemorrhage. Identifying the appropriate transfusion strategy is mandatory prior to adopting prehospital hemostatic resuscitation strategies. ⋯ A balanced resuscitation strategy demonstrates an early survival benefit, decreased death from exsanguination at 24 hours and a greater likelihood of achieving hemostasis in critically injured patients receiving a 1:1:1 ratio of plasma:platelets:PRBCs. This finding highlights the need to import DCR principals to remote locations.
