Hemorrhage is the leading cause of preventable death on the battlefield.6 Of the 4,596 combat deaths reported in COL Brian Eastridge’s 2012 review Death on the Battlefield, 976 casualties died with injuries that an expert panel classified as potentially survivable, and the vast majority of these deaths—just over 90%—were secondary to uncontrolled hemorrhage. Subsequent interventions focusing on point of injury hemorrhage control and prehospital Tactical Combat Casualty Care were predictably successful, and particularly when paired with rapid evacuation and prehospital blood resuscitation. In fact, data published in studies by Col Stacy Shackelford et al. showed that blood given in the prehospital setting as soon as possible after injury improved both 24 hour and 30-day survival.7 In short, in the setting of active hemorrhage, the combination of point-of-injury hemorrhage control (per Tactical Combat Casualty Care guidelines), rapid evacuation, and pre-hospital blood resuscitation saves lives.
