The foam can reduce blood loss six-fold and boost the rate of survival at three hours post-injury to 72 percent

A new type of foam that is injected into the body could save the lives of countless soldiers wounded on the battlefield.

The U.S. Department of Defense's (DOD) Defense Advanced Research Projects Agency (DARPA) has been working with a medical company that can help soldiers survive internal abdominal injuries and internal hemorrhaging.

The DOD strives to accomplish what is known as the "Golden Hour," which transports a wounded soldier to a medical facility in under an hour. However, for those suffering from internal abdominal injuries and internal hemorrhaging, their chances of surviving an entire hour with a large amount of blood loss are quite slim. 

Currently, there are limited solutions for temporarily taking care of internal hemorrhaging while transporting a soldier to the hospital. Internal wounds cannot be compressed, and tourniquets and hemostatic dressings cannot be used due to the need to see the actual injury.

To address this issue, DARPA started the Wound Stasis System program in 2010. Through the program, it found Arsenal Medical, Inc., which developed the new foam method.

This is how the foam works: two liquid phases are injected into the abdominal cavity. The first liquid phase is a polyol phase, and the second is a isocyanate phase. When these two liquids are combined, they two different reactions take place. The first expands the liquid to about 30 times its original volume where it fits the surfaces of the injured tissue. The second transforms the liquid into solid foam, which becomes a polyurethane polymer. It is capable of resisting intra-abdominal blood loss, and can expand through both pooled and clotted blood.

The foam, which can be quickly and easily removed by doctors once the soldier is taken to the medical facility, can reduce blood loss six-fold and heighten the rate of survival at three hours post-injury to 72 percent. This number was at 8 percent without the foam. The foam showed that it could treat a lethal liver injury for three hours before reaching medical treatment.

“Wound Stasis has been an exciting program because we were able to move unexpectedly from fundamental research to a pre-clinical proof-of-concept based on the strength of our findings,” said Brian Holloway, DARPA program manager. “According to the U.S. Army Institute of Surgical Research, internal hemorrhage is the leading cause of potentially survivable deaths on the battlefield, so the Wound Stasis effort should ultimately translate into an increased rate of survival among warfighters. If testing bears out, the foam technology could affect up to 50 percent of potentially survivable battlefield wounds. We look forward to working with the U.S. Food and Drug Administration on future regulatory submission of this device, and with our partners, the Army Institute of Surgical Research and Special Operations Command, on getting this technology to where it’s desperately needed on the front lines.”

DARPA gave Arsenal Medical, Inc. $15.5 million for Phase II of foam development.

As an American Veteran

Sorry to hear that, no human being deserves to be in a war, even voluntarily as you.

but you do it for the greater good of your country

I'd rather serve my country, my community and my family in ways that don't imply having to kill other human beings.

you are that self entitled and conceited

I'm neither. I just said that because unfortunately there are Americans in a needy situation for whom the tax and grant benefits may be the main reason for enlisting. No one should go to war to get out of poverty.

Talk all you want about how superior your country is, but chances are that we have either saved you in the past or beat you.

Actually, neither, but that's besides the point. What worries me about this sentence is that apparently you think that when a country defeats another one in a war, then the victorious country is somehow "superior" to the defeated one. To me, superiority is never decided in a war.

Anyway, I hope you find less violent ways to serve your country in the future.

Thank our families. It's easy to sacrifice ourselves, it's hard to leave those behind who are used to having our support and love as a daily part of their lives.

Truth be told, they call it serving because even if it seems like we get paid well, when you consider what we do we really give up there is no amount of money that can make it worth it sometimes. We forgo births, graduations, deaths, weddings, nights out, nights in, amazing home cooked meals, celebrations of all types, disasters and family crisis' that we really need to be there for, etc. I don't think anyone who has ever signed a six year enlistment form fully realizes the sacrifices they will make until they are making them.

When we pack up and leave for half a year with little to no notice we have to be sure that our family will be taken care of while we're gone. We aren't there to fix the car, to provide protection, to pick up the kids from school. Spouses and significant others say time and again that the first deployment is a lot harder than they thought it would be.

That's just the sacrifice we make when we board the plane.

Overseas it's another story.

Time passes more slowly for those back home sometimes, as the military can keep us up to our necks with work. We're around people all day, and sometimes it would be great to just have some alone time.

Sometimes we get paid to do nothing all day. It sound easy, but that's just it; We're securing an area, a base, etc and while our minds want to shut off and zone out, we're supposed to be acutely aware of our surroundings. It's tough, and if we fall asleep on the job we can be arrested by our own team.

To make it harder...imagine sweating all day in an uncomfortable uniform (You'll drink so much crappy warm bottled water that you'd do anything for a beer, hence why we end up with so many drinking problems probably), lugging around gear, being bossed around and not being able to respond with a word for fear of reprimand, with a desire for your stomach to "just get right" and stop feeling like you need to use the nasty portable toilet every other minute.

Meanwhile your feet are warm and burning a bit from the fungus that's set in, most of us get it at least a little.

Add to that not being able to sleep real well in a small uncomfortable bed with gunshots/industrial noises/pollution/lights/etc all around.

Consider that you're eating the same bland food every week, sometimes the same food twice in one day. If you're lucky, you may get the additional wonderment of eating MRE's morning noon and night. Granted, many people around the world experience boring sustenance in daily life as civilians. We American's have such a cozy lifestyle.

Where was I, ahh yes. Still think it sounds easy? Now eat the same slop for a year. Get shot at, scan the road ahead for IEDs, watch your buddies die in front of you.

Now you realize how little we get paid for the sacrifices we take. One more thing, at least with what I do, I am also expected to advance in my career. Training is constant, and leadership abilities WILL be developed or I won't have the option to re-enlist.

There are sometimes parts of this job that are downright disgusting, tough, uncomfortable, and annoying. In the end it all equals stress. That's what a mere two months of basic training (boot camp) is for. It's a test to see if you have what it takes to simply endure. Those who wash out usually do so by choice. The American military doesn't want anyone in a crappy environment who doesn't want to be there. That's why it's the world's largest all-volunteer force.

Sadly, BMT has gone a bit soft and there are a lot of people slipping through who probably shouldn't, in my opinion.

For anyone who deploys as an enlisted member of the armed services to some craphole on the other side of the world, you have my respect. Bottom of the shot glass up to you my friend.

As another poster said, the military operates in a way where "you don't get a choice." Sure, it's a voluntary force but you really do sort of sign your life away.

"Not feeling well? Get your ass to your post, we have to get this done."

Sometimes we're handling weapons, and most often we are in dangerous/extreme temperatures territories. Bases in Afghanistan are within range of Iranian missles. When diplomatic relations in a region are tense you will hear and feel it from the locals that you are likely to encounter.

It's all just a lot to take home and digest. Even those who don't see combat can suffer from PTSD. It's no joke. Anyone with a won't fully agree with what our (America's) government does 100% of the time, and that includes members of our military. Don't judge our troops, give them the respect they deserve. Nothing is more appalling than to see deceased persons having funerals and graves disrespected by the very civilians they seek to protect. We're trying to make a living and trying to keep America's civilian population safe. For anyone who may not understand how a strong military force does that I would suggest studying history, governments, human evolution and human psyche a bit more.

Some individuals of the military are just kids learning lessons about responsiblity, diversity, etc. and a select few will choose to learn some serious lessons the hard way. Do not let them detract from the millions doing their jobs to the best of their ability. I personally know many outstanding people where I work. As a base we are fighting to stay open amid the budget constraints, but our base history gives us a good fighting chance and I believe we will remain open.

As you celebrate the holidays this season, remember those who are around globe, away from their families, just doing their jobs.

Support our troops.

As hard as I tried to get it without errors...

I respected the military in the past, but times have changed and currently it's mainly being used as hired thugs for the rich. The problems America faces are not ones where it'll get invaded, and it's why there are vets who are calling for the return of troops and a shame only Ron Paul was actively supporting this.

If you want respect beyond that given to a normal person simply for living a crappy life for some false ideals in the protection of the people, then tough, violence isn't the answer to everything.

If you think violence is all the military does, you're wrong. Sure, there are gung-ho kids with guns but for the most part we are peace keepers. Around the world, there are men trying to take power and do whatever they want to the civilian populations. American's live in a bubble of freedom, and don't realize that the rights we have so quickly taken for granted (i.e. women gained rights in America not that long ago, and sadly people are still judged for what they are and not who they are [homosexuals]). In other parts of the world there are people being slaughtered, loved ones raped and beaten, and land being stolen for the sake of greed. Greed is rampant, it's a global problem that isn't going away anytime soon. That said, it's American's that so often stand in the gap and stop such atrocities. Before joining the Air Force at age 29, I was a lot like you.

Today I find myself much more educated about how government works, etc. Why? Because I got out there and got involved. Joining the military isn't about killing people for me, it's about being ready to defend my homeland, helping out my community in natural disasters, volunteerism, taking care of my family, and strengthening myself - physically, mentality, and educationally.

If you want respect beyond an anonymous poster online who doesn't really understand his or her own government, well then maybe you'll have to educate yourself about who our military really consists of. Where I work, it isn't all young dumb kids. There are doctors, lawyers, skilled mechanics, network specialists, electricians, etc.

Do yourself a favor, take a chance and get involved.

Ugh, I need an edit button. Pardon me for not proofreading more.

This should say "Americans live in a bubble of freedom, and often we don't realize that the rights we quickly take for granted don't extend to a large portion of the rest of the world. I was overseas for seven months of the last year and I can tell you that women in some nations in the east live in fear of being beaten, raped, etc.

When you realize what goes on, how can you NOT want to rise up and put a stop to it? Maybe you only care about yourself.

Anyway, I hope you find less violent ways to serve your country in the future.

If there are none willing to serve in the military then a country, any country, would not survive long as they would be invaded and conquered with little resistance. There will always be a place for someone to serve in support roles such as logistics or health care as you would like to serve, but there will always be a need for military service to compliment the non-military service.

It has pretty much been proven over thousands of years that there will be certain of the human race that will have a desire to conquer just as there are ones that have a desire for peace. Be thankful that there are those with the desire for peace who also realize that sometimes force is necessary to keep the conquering element under control.
