«The problem is that
damage from
bullets and bone fragments deep inside a junctional
wound is not always visible from outside the body, and a regular clotting agent may not be able to reach the origin of the bleeding,» said Sydney Rooney, leader of the biomedical engineering student team that sought to solve this problem.
Further, the
wound would have been much more
damaging had the
bullet ricocheted off the inside of her skull or if it had remained lodged in her brain matter where it could «migrate around» and cause additional harm, Black says.
