Coming Technology: Stop Abdominal Bleeding With Foam
Foam is used for everything. Firefighting. Impact resistance. Law enforcement. Now a company working with DARPA has developed a foam to slow intra-abdominal bleeding until the patient can get to a definitive care hospital. This concept has been used successfully in pigs and slows uncontrolled liver hemorrhage, increasing survival from 7% to 72%.
It is hoped that the foam can be used in the battlefield, and is simple enough to be administered by a combat medic. A small plastic trochar is introduced into the abdominal cavity and two liquids are injected, like epoxy. They react and fill the abdomen with foam, which slows active bleeding.
Like so many military innovations, this may ultimately work its way down to urban EMS units for use in penetrating trauma. Keep an eye on this interesting technology.
