Researchers create self-propelled powder to stop bleeding
 

Traditional methods of halting severe bleeding are not very effective when the blood loss originates inside the body like the uterus, sinus or abdomen.

Researchers developed a simple, gas-generating calcium carbonate micro-particles that can be applied in powder form to stop critical bleeding.

The carbonate forms porous micro particles that can bind with a clotting agent known as tranexamic acid, and transport it through wounds and deep into the damaged tissue.

After studying and modeling the movement of the particles in vitro, the researchers confirmed their results using two animal models. Even in a scenario that mimicked a catastrophic event like a gunshot wound to a femoral artery, the particles proved highly effective in stopping the bleeding.

While much more rigorous testing and development is needed to bring the agent to market, the particles could have a wide range of uses, from sinus operations to treating combat wounds.
