While cloth gauze has been the standard since World War I, a new high-tech gauze may soon be saving lives

Nanoparticles are one of the hottest fields of studies.  These tiny molecules promise to revolutionize everything from medicine, to computing, to power, to water purification.  The diverse uses being discovered are only limited by the difficulties in bringing this incredibly promising technology to market.

Now the scientific community is enthralled by a perhaps unexpected new use of the particles -- high-tech gauze.  By using a special gauze fabric, permeated with Kaolin clay which is rich in aluminosilicate nanoparticles, scientists have discovered they can dramatically improve the chances of inducing clotting yielding results that are nothing short of a medical miracles.

The gauze bandage is easy to apply and greatly improves clotting in hard to apply regions such as the neck or groin.  This makes it ideal for the battlefield.  In recent conflicts, such as the Iraq war, many of the casualties have been due to blood loss.  The new gauze could soon be saving lives. 

Richard McCarron, head of trauma and resuscitative medicine at the Naval Medical Research Center in Maryland stated, "We are currently testing bandages because hemorrhage is a leading cause of death in military trauma patients.  The recent tests with Combat Gauze indicate that it decreased blood loss and improved survival."

Z-Medica, a medical products company located in Connecticut, manufactures the high tech gauze.  Z-Medica CEO Ray Huey says the new gauze has already saved two lives.  Huey describes his company's start, stating, "In 2002, following the September 11 attacks, the military was looking at new technologies to stop bleeding."

The company easily won the Navy's test of high-tech medical products, according to Huey, when Z-Medica debuted its first product, QuikClot, a special powder dumped on wounds to induce clotting.  The powder is currently in use in Afghanistan and Iraq.  However, despite saving lives QuikClot had some nasty side effects.  During the clotting process, the powder heated up enough to cause burns, which many of the soldiers complained of.  While burns were better than dying, Z-Medica went back to work looking for a better solution.

A leading materials researcher Galen Stucky led a team of several graduate students and collaborated with Z-Medica to solve the problem.  Stucky's solution was to instead use a material frequently used in medical testing -- Kaolin Clay.  The clay's nanoparticles trigger clotting.

Graduate student April Sawvel explains, "Kaolin clay has been used since the 1950s as an activating agent for a clotting test that medical doctors routinely perform.  We tested it against the original granular QuikClot and discovered that it worked just as well, but without the large heat release associated with the original QuikClot formulation."

While some nanoparticles are thought to possibly be hazardous, there is little known risk from aluminosilicate nanoparticles, which mankind has been in contact with since its early days.  Further, the nanoparticles are trapped by the clot at the site of the injury, so should have little chance of traveling into the body.

Having found the new material the team found that it was much easier to use it, when it was added to gauze, instead of a powder.  Huey describes, "We immediately started looking at ways to impregnate gauze with this material.  We very quickly prototyped some material. When I say very quickly, I mean within less than two weeks."

Now the company is commercially producing the gauze for Special Forces operators, the Coast Guard, and emergency-room doctors.  In a medical trial, the gauze stopped bleeding of a normally fatal cut to the aorta of a pig's heart (video).  Pigs share common anatomy and physiology in many ways to humans, so this shows the power of the new product.

Hopefully the soldier will come first in deploying this new gauze. Not some politicians agenda.

The article clearly says that it was tested on a politician first. Yeah, apparently their hearts are very anatomically similar to normal human hearts.

But yes, this will save lives, not just in the battlefield, but in day to day road accidents, stabbings, etc.

Lies!
Lies I say!
Everyone knows the main anatomical difference from a politician and the rest of the population is that their hearts have been relocated to their wallets.

Gauze costs money just as any other commodity. I am sure a large sum of $ is involved with a government contract.

Don't get me wrong this sounds like an excellent thing that could truly benefit us all someday but nobody should be so cynical as to think them any different from pharmaceutical companies... Its still business as usual.

Everyone knows the only way to kill a politician is a wooden stake through the heart. The only question is how do you kill a politician who has left his wallet at home?

But on a more serious note, this is pretty awesome.

The businessman will come first. Then the politicians will be going on about how they brought it to the troops and how they're such heroes.

That quickclot is nice but they didn't mention the other nasty danger of it. If you breathed the powder in, it'll react with the moisture in your lungs then heat and clot up. Nasty stuff.

I wasn't impressed until I watched the video of the gauze stopping an aortal hemmorhage. The blood in this area is under tremendous pressure; such bleeding can be incredibly difficult to stop.

You know somewhere there's someone complaining about the rights of the pig.

But I must agree, that was very impressive. But what happens if a carotid or femoral artery is severed? Or is this a one-breakthrough-at-a-time thing?

> "You know somewhere there's someone complaining about the rights of the pig."

There's a special place in hell for animal rights activists who oppose medical experimentation.

As for other arteries such as the carotid...if this can stop aortal bleeding, it can stop anything. The pressure is highest there; nowhere else is it quite as difficult.

I hope those two weren't complaining... but I wouldn't be surprised! Everyone who's done tech support knows that you really can't please some people.... ;)

While Quikclot does work in the way that it's claimed to work. (It stops the bleeding of major wounds) The company is greatly underexaggerating just how "hot" the powder gets. In a controlled environment you would clean up as much fluid (ie. blood) as you can from the area because the agent works when it comes into contact with any kind of liquid.

In a field environment however, you're going to want to just get the bleeding taken care of as quickly as possible so doing a quick mop up is probably the best you're going to get. When the Quikclot is applied with that amount of liquid having second and third degree burns is the standard. I've also heard that the Marines have pulled Quikclot from their kits because of how harmful it can be to the rescuer as well. When they treat their injured and get blood on their hands and use this, it's not uncommon for the rescuers hands to become burned when applying the powder to the wound.

Bottom Line: For life or death situations then go ahead and throw some of the powder on and save my life. If it can be stopped in any other way then don't even think about letting me anywhere near that stuff...and yes, if it hurts i'm going to complain, but doesn't everybody?

A new poll suggests that nano particles will bring about World Peace, end Global Warming, food and shelter for the World's homeless, sustainable renewable energy cheaper than oil and coal, and is the Savior of Mankind. Move over Yeshua, nano particles have replaced you.

Nano particles killed my father, and raped my mother. Nano particles are also the reason that I'm out of job, fat, stupid, lazy, have every phobia related to human interaction, and that the economy is bad.

...just playing devil's advocate. =)

Well, I was looking forward to my own Nano-suit, but now I'm conflicted. I mean, if it's made of clay-impregnated gauze, I suspect I will look just plain silly.

I wonder how long it will take for this to migrate to our children. "Going out to ride bikes, champ? Go put on your helmet and your padded gauze suit."


Great idea come to fruition

Unfortunately, the argument that it is going to be widespread-adopted by the US military is half-baked.

The US military removed the tourniquet from standard issue for a large majority of the beginning of the Wars in Iraq and Afghanistan. This had been standard issue for many many decades. The direct result was many soldiers losing their lives due to bleeding out from wounds of the extremities.
This, combined with the fact that families of soldiers had to buy silly-string (to detect trips), body armour, and communications equipment and send it to their sons because the army didn't have enough does not bode well. Many of the things sent over weren't allowed to be used- such as body armour and communications equipment, because it wasn't standard issue. It's sad to see hypocrisy and bureaucracy leeching its way into warzones and being responsible for deaths.
Modern army my ass- we might be adding a lot more technology, but we're not providing enough to protect that mortal flesh that we should venerate as the backbone of our military.

They complain about military spending and then they complain that the military isn't spending enough. Brilliant.

Great news, but am I the only one that finds the use of the term "nano-particles" becoming a bit, well obscene? What exactly makes these "particles" nano-particles? Are all atoms now going to be called nanoparticles?

Nanoparticles are particles with at least one dimension between 10nm and 100nm.
