Shrimp Bandages Clot Blood Faster 384

Posted by CowboyNeal from the underwater-allies dept.
dwbryson writes "A new bandage technology uses ground up shrimp shells to instantly clot blood when applied to an open wound. These new bandages were developed and are being produced exclusively for the military (at $100 for a 4x4" square), but the company who makes them is hoping to mass market them to general consumers."

      Those are indirect causes.
    • Oh... I thought it was bullets or bombs.

      Modern bullets are designed to disable, but not kill people. The idea is that it takes fewer support troops to get rid of a dead soldier than it takes to transport and treat an injured soldier. As a result, armies want to maim their opponents, not kill them.
      • Furthermore, relaxing the requirement to atomize the opponent lets the rounds be smaller, translating into more shots per soldier for a combat load.
    • Well, the end result of getting hit with a bullet or a bomb is in fact massive blood loss.

      So yes, bleeding is the largest cause of death. :)

    • I'm not surprised bleeding is a problem, but will a clotting agent stop it?

      I would think once you open up an artery or three, clotting is beside the point.

    There are two uses for bandages: one is primary treatment of minor skin wounds, and the other is stabilizing a major wound until real treatment can be given to it. At $100, this is too pricey for a first-aid kit unless you're in a really high-risk situation for major trauma -- the only place outside of the military which strikes me as obvious is a construction site. Its not the sort of thing you can justify putting in the school room first aid kit. There's no real reason to give them to hospitals, since anyone requiring wound healing urgently enough to go to a hospital likely has other problems and has other, more HMO-approved solutions (like regular bandages, which work just fine at preventing you from bleeding to death when administered properly and not overwhelmed by the trauma).

    The company freely admits that the bandage is composed of a very ubiquitous shrimp-derived compound and vinegar. So why $100 a bandage? Either because:

    1 - Their product is difficult to manufacture
    2 - They give money back to the Wild Shrimp Rights Society

      Since the article is recycled, allow me to recycle my post from the last time this exact same subject was discussed on slashdot.

      Read about some of the reasons why meds are so expensive [yarchive.net].

      Apologies for the length of this quote from the above link, but I think it's worth reading (Steve Harris MD on medical costs and litigation):

      "...You [Steve's correspondent] were complaining about the cost of American medical care not long ago. You are clueless as to the connection here. Drugs cost more here. Medicine costs more here. A lawyer costs more here. An artitect costs more here. Each of these things has reasons. Until you step away from medicine and see the big picture, you'll never figure it out...

      ... And that's not even the worst part. The worst part is what you don't see. The products that are never developed, or developed too late to help people, because everyone is afraid that somebody will get hurt, and sue. In the case of vaccines it got so bad that without DIRECT government intervention to hamstring the civil litigation process, you would not today be able to buy a dose of vaccine in the United States for love or money. The very last couple of makers were getting set to leave the U.S. market and sell only overseas, before the government stepped in and stopped an out of control civil litigation process...

      ...For less obvious things than vaccines and aircraft, FYI, the government does not step in, and the product you don't know about simply ceases to exist. If you need a lung lavage of fluorocarbon to save your life if you have lung damage from a fire or shock, you're not going to get it. 3M, which makes most of these chemicals, quite deliberately got out of the medical market years ago, after the Dow Corning Silicone suit. So you're out of luck. You won't know why, but that won't change a thing. If your heart valve fails, you'll never know that it might not have, if the suture 3M made for that purpose, in a little tiny subdivision of the company, was still available. But it's not, since a giant company like 3M has deep pockets, and they don't need the medical market liability grief. Now, it's YOUR problem."

        Not only is the litigation off-the-deep-end crazy here, but drugs that are necessary but less profitable than things like Viagra sometimes simply disappear off the market.

        Take Eflornithine, the best drug available for treating Sleeping Sickness [wikipedia.org]. Obviously, Sleeping Sickness is not a big problem in the US, where we all have lots of money to buy drugs. It's a problem in Africa, where they don't. So what did Aventis, the manufacturer do? They stopped making it in 1995. It took SIX YEARS for the WHO to manage to talk Aventis into letting someone else manufacture it in 2001.

        To recap: a drug company SAT ON A VITAL DRUG for SIX YEARS because they didn't find it "profitable enough," yet wouldn't let anybody else manufacture it to save lives.

        The other drugs for treating Sleeping Sickness are nearly as bad as the disease. A huge fraction of the people treated with melarsoprol die when it causes reactive encephalopathy (convulsions, coma, etc...) and those that live often have brain damage.

        Of course, the second Aventis discovered (recently) that the drug can be used to remove unwanted facial hair in women (now THERE is a profitable use for a drug!) they cranked right back up into production. Saving lives? Not profitable enough-- we won't make it. Facial hair removal? Crank up the factories!!

        It appears since this fiasco that Aventis has cleaned up their act and is donating $5M a year worth of the drug to Doctors Without Borders-- but how many died unnecessarily?

        And on the litigation front, I know an EM resident who is being sued by the sons of a patient (all three are lawyers). They are upset because the hospital wanted to move the woman, whose condition was stable, out of the ICU and into long-term hospice care. These assholes are why your medical costs are so high.

        Sorry for the rant-- this stuff makes me incredibly angry.

    Interesting stuff, chitosan. It's a family of oligosaccarides, not a single chemical, and until recently was mostly consider a waste product. Leately though, it's apparently become some sort of fad diet aid as well, one of those alleged 'fat blockers' that are probably total BS. It also used as an emulsifier (an additive which keeps different liquid parts of the food from separating), as a livestock feed. In addition to the clotting action, it supposedly has some anti-bacterial and anti-fungal properties, though how much so isn't said.

    While it is mostly derived from seafood shell left from food processing, it can also be extracted from certain fungi, which actually produce it in much larger quantities. This means that it probably will be cheaper in the long run to synthesize it industrially using the fungi rather than harvesting it from shellfish, though unless the market for (or populations of) shrimp and crab suddenly nosedives, they'll probably keep doing that as well (they have to do something with the shells, after all).
