Internal bleeding can sometimes be life-threatening. It is currently one of the leading causes of death worldwide, especially on the battlefield.

To deal with this problem, scientists at Texas A&M University created an injectable bandage made from very common food ingredients and nanoparticles. This amazing bandage can not only stop bleeding within minutes but can also promote the healing of damaged tissue.

Sounds extremely promising. The problems with presently used internal clotting agents such as vitamin K and others, is that 1) they may not work fast enough 2) they can cause unwanted blood clots, a very serious side effect  3) they cause increased viscosity of the blood which can increase blood pressure and reduce the blood supply to stressed organs, and can cause strokes 4) these agents cause reduced blood circulation which can stress the heart.

 

It seems likely that this new clotting agent, likened to a bandage, would have fewer of these unwanted side effects.

 

According to the article, testing has only been done on animals so far, but with such promise it seems likely that human trials and testing will be approved ASAP, especially for critical internal injuries such as from combat, auto and other accidents, etc.
