Researchers at Penn State College of Medicine are working on a quick-acting foam for treating life threatening injuries. The foam when placed into the injury site, expands and converts into a gel, stopping the flow of blood. Over time the foam is broken down naturally by the body, into sugar, which can easily be metabolized by the patient. This way, the foam does not damage the surrounding tissues or cause further injuries like traditional trauma bandages. The hope is to not only apply this technology to treating wounds on the battlefield, but also for use by first responders.
