The Surviving Blood Loss (SBL) program is developing novel strategies to radically extend the time injured warfighters can survive critical blood loss on the battlefield before initiation of fluid and blood resuscitation. Achieving this goal will allow increased time—as much as hours or days—for evacuation, triage, and initiation of supportive therapies.
Uncontrolled blood loss is the leading cause of death for warfighters on the battlefield, according to the U.S. Army Institute of Surgical Research. The vast majority of such fatalities are from wounds that are not accessible by combat medics for traditional treatments, like direct compression. For example, in the case of internal injuries to the abdominal cavity, medics can neither visualize the damage nor access it to provide treatment. As a result, rapid and uncontrolled blood loss often leads to death before transport from the battlefield to a surgical setting can occur.
