Scientists Found A New Way To Stop Bleeding Using Sprayable Foam

Scientists have developed a new method to help battle major injuries for first responders and combat soldiers.

The new anti-bleeding material originates from shrimp shells and is later developed into a spraying foam. This new sprayable whipped cream-like foam can significantly stop bleeding for even the most chronic open wounds, RT reported on Wednesday.

The sprayable polymer-based foam can be significantly vital for treating major injuries in street violence and combat zones.

According to an ACS Biomaterials Science & Engineering study, the sprayable foam is based on an Amphiphilic Biopolymer, and should be primarly used when compression is not an option for treating Hemorrhage.

Researchers who conducted the study made the following consideration.

“Hemorrhage (severe blood loss) from traumatic injury is a leading cause of death for soldiers in combat and for young civilians. In some cases, hemorrhage can be stopped by applying compression of a tourniquet or bandage at the injury site. However, the majority of hemorrhages that prove fatal are “non-compressible”, such as those due to an internal injury in the truncal region.”

They followed by stating, “Currently, there is no effective way to treat such injuries. In this initial study, we demonstrate that a sprayable polymer-based foam can be effective at treating bleeding from soft tissue without the need for compression.”

The active material — chitosan (a biopolymer derived from the shells of shrimp and other crustaceans) — is said by researchers to be used to “physically connect blood cells into clusters via hydrophobic interactions,” Business Insider reported.

With an exciting new method to stop bleeding in the works, researchers initiated several tests using the foam. Researchers found success after restricting blood from an injury to the liver of pigs. According to reports, “within a few minutes” of using the foam, bleeding from the pig’s injuries stopped.

Of course, without the use of compression and only the foam, about 90 percent blood loss was prevented.

This new discovery of shrimp shell based foam came at a time where in 2013, most Americans under 45 died from injuries rather than diseases. This makes trauma the leading cause of death.

Furthermore, injuries — which are synonymous with violence — accounts for nearly one in every 10 deaths worldwide each year, according to the U.S. Centers for Disease Control and Prevention.

However, scientists are refusing to hang their hats on this and plan to conduct further research on other methods that may also potentially treat severe blood loss.
