A New Bandage that Will Stop Bleeding Instantly

Thrombin is an enzime that is available in our body. It is also a medication that is used in hospitals, as a coagulant. It stops bleeding instantly.

But till now it was not used for the battle fields, which is a place that it is needed so much due due to it is not practical in transferring to the battle fields.

MIT researchers have reached a new breakthrough that will allow using thrombin in the battle fields and save

a lot of soldiers lives.

The researchers, led by Paula Hammond and funded by MIT’s Institute of Soldier Nanotechnologies and a Denmark-based company, Ferrosan Medical Devices A/S, created a spray coating that includes thrombin, a clotting agent found in blood. Sponges coated with this material can be stored stably and easily carried by soldiers or medical personnel. The sponges could also prove valuable in civilian hospitals, says Hammond, the David H. Koch Professor in Engineering.
Uncontrolled bleeding is the leading cause of trauma death on the battlefield. Traditional methods to halt bleeding, such as tourniquets, are not suitable for the neck and many other parts of the body. In recent years, researchers have tried alternative approaches, all of which have some disadvantages. Fibrin dressings and glues have a short shelf life and can cause an adverse immune response, and zeolite powders are difficult to apply under windy conditions and can cause severe burns. Another option is bandages made of chitosan, a derivative of the primary structural material of shellfish exoskeletons. Those bandages have had some success but can be difficult to mold to fit complex wounds.
