Bleeding internally? Seal it with this DARPA foam

While any soldier dreads the idea of being shot, sustaining an internal abdominal injury from an explosion or other impact can be far worse. Bleeding from wounds that can’t be compressed causes some 85 percent of preventible battlefield deaths.

As part of DARPA’s Wound Stasis program, Arsenal Medical has developed an injectable polymer foam that expands inside the body to stanch internal bleeding.

The concept of foam growing in the body reminds me of that 1980s B-horror film The Stuff, but apparently it’s effective.

Based on testing in pigs, DARPA says the product can control hemorrhaging in an abdominal cavity for at least an hour, a critical window to get the soldier to a medical facility.

“During testing, minimally invasive application of the product reduced blood loss six-fold and increased the rate of survival at three hours post-injury to 72 percent from the eight percent observed in controls,” DARPA said in a release.
