Blood-clotting bandage to help save lives on the battlefieldPublished On: Sun, Jan 30th, 2011 | Health | By BioNews
Scottish scientists are developing a new chemical bandage that will help save lives on the battlefield by instantly helping to clot blood and staunch wounds.
The authors have discovered a group of polymers – molecules used in the manufacture of plastics – that accelerate the crucial clotting properties of platelets in blood, reports the Scotsman.
The polymers could have significant use in battlefield conditions as they can be sprayed on to bandages and applied directly to an injury to instantly begin the coagulation process, say researchers at Edinburgh University.
The research team was led by Mark Bradley, Professor of High-Throughput Chemical Biology, and Anne Hansen at the university’s Chemical Sciences school.
The problem of treating battlefield wounds remains a major challenge with “bleeding out” – the loss of too much blood to sustain pressure and heartbeat – one of the major causes of death after injury.
The polymers could also have a much wider use in civilian life if incorporated into the sticking plasters commonly used to stop blood flow from cuts and other injuries.
Not only do they speed up the clotting process, they are also believed to prolong how long clots last.
