Researchers at the University of B.C. have devised a way to deliver blood-clotting drugs on a jet of bubbles deep into a wound even against a heavy flow of blood, a potentially game-changing advance in trauma medicine.

“We were interested in treating hemorrhage, especially in childbirth,” said UBC biochemist Christian Kastrup. “The problem is that it’s really hard to push drugs into a wound against severe blood flow and far enough upstream to reach the source of the bleeding.”

Kastrup, in collaboration with a group of other researchers, biomedical engineers and emergency physicians, developed calcium carbonate micro-particles that bind with a clotting agent and release carbon dioxide gas, which propels the medication in every direction, including to the source of the bleeding.
