US researchers have developed a spray foam which they claim can be injected into a wounded soldier's abdominal cavity to help stop internal bleeding.
When soldiers are wounded on the battlefield, getting them to advanced-level treatment facilities within the first 60 minutes of injury often makes the difference between life and death.
During this hour, internal bleeding - particularly in the abdominal cavity - is life-threatening because there is little that can be done to stop the bleeding, Discovery News reported.
Researchers from the US Defense Advanced Research Projects Agency (DARPA) who developed the foam hope it can help the wounded survive until they get to treatment facilities.
The polyurethane polymer foam can be injected by a field medic in two liquid phases, a polyol phase and an isocyanate phase. When the liquids mix, they expand to 30 times their original volume.
As it expands, the foam fills the abdominal cavity and conforms to the surface of the injured tissue and organs. The foam then hardens, providing resistance to intra-abdominal blood loss.
DARPA said the foam can even expand through pooled and clotted blood.
During tests, removal of the foam took less than one minute after an incision by a surgeon. Only minimal amounts of the foam remained in the abdominal cavity and no significant amount of tissue stuck to the foam.
No human tests have been conducted yet. However, tests on swine did show that the foam raised survival rates for liver injuries after three hours from eight to 72 per cent and reduced blood loss by six fold.
