French Doctors to Perform Zero-Gravity Surgery 222

STFS writes "NewScientistSpace has a story about a team of French doctors who will attempt the worlds first zero-gravity operation on a human aboard an Airbus A300 dubbed "Zero-G". The patient, according to forbes.com, was chosen because of his experience with 'dramatic gravitational shifts' as an avid bungee-jumper. The operation will serve as a test for performing surgery in space."

    ... I predict some serious mishaps for all involved. The Vomit Comet is a NASA plane which they use to simulate 0G conditions by the simple expedient of taking the plane up really high and then flying it towards the ground, then pulling up and repeating. As I recall the cycle between weightless and "really freaking heavy" takes about 60 seconds, with about half of that time being weightless. Any more and the plane ends up as NASA's 453rd "premature interface of craft and planet". So the surgery would be stopping and starting constantly, and as most surgeries aren't five-minute affairs I can imagine that would be a little irksome.

      I've seen footage of people on the Vomit Comet, and for something that's supposedly weightless, it's amazing how much time they spent on the floor of the plane, or drifting towards it. It wasn't really weightless so much as really-really-light.

        Even in space, it is not actually 'weightless', there is still the gravity that holds the celestial bodies in orbit. While the plane may make it more like .01 G instead of .000001 G, it's not as if it's entirely a different thing from being in space (microgravity is the term).

      Sounds like removal of a "lipoma". (I've had a few of those removed.)

      Think of it as "cancer of the fat" - except benign. You get stiff fatty lumps (maybe one, maybe a scattering, maybe like a bunch of grapes). They're like regular fat with some kind of other tissue in them that makes them hard.

      It's really annoying if it's above a muscle or some other easily hurt tissue: It's like a rock embedded in the fat that is SUPPOSED to be cushioning the tissue, so lying on it bruises the tissue instead.

      They never go malignant so doctors will leave them in unless they're bruising something underneath or causing a disfiguring bump. They're near the surface of the skin so they're easy to cut out - usually by a dermatologist.

      Sounds like the perfect test operation. Not a big deal if they don't get it all, near the surface so you don't have to cut through vital stuff or clamp stuff out of the way to get to it, etc. Easy to tell how well the op went. Much less opportunity for screwups than just about any other surgery.

        A lipoma is benign, however they can undergo malignant transformation - just like any tissue in the body. Generally the small (5 cm and deep to the fascia ( a gristly layer over the muscle) tend to malignantly transform and should be excised.

        Dermatologist generally don't do cancer operations - they take out skin lesions a bit at a time untill they hit healthy tissue. If something is deep to the skin - i.e. a lipoma, it should be removed by a surgeon (general, or orthopaedic) that specialises in oncology. The only real way to determine if they are benign is to examine it pathologically. Generally the benign ones tend to be soft, ,the bad ones tend to be firmer and look funny on MRI.

    As well as the challenge of working in zero gravity, the surgical team will have to halt their work each time the plane pulls out and gravity resumes."


    22 seconds multiplied by 30 is 660 seconds, that is only 11 minutes of surgery for 3 hours. I wonder if that tumor could be removed during this 3 hour session.

      It has been done on animals. I worked with a NASA surgical research group for years and one of the many projects we did was surgical simulation (both computer with haptic feedback and with traditional box simulators) in microgravity. Other groups did surgical procedures on animals in microgravity. We've flown every possible piece of the puzzle, many times. This is the logical next step, and yes it is experimental, but that's what researchers do.

      There are many things that could go wrong, and no doubt they'll tell the pilot to level the plane if that happens. Being in control of the gravity makes it a lot safer than trying it for the first time in an emergency aboard the space station. Sooner or later this has to be done -- I admit when I first heard this story on the news, I was hoping it was my old group doing it.

      Probably constant dabbing with sponges or gauze would be useful in stopping the blood from flying away...but keep in mind...the surface tension of blood will keep it sticky to the site of incision, the instruments, and to their gloves. That is of course assuming they don't cut a high pressure spurting artery...then all bets are off. Point is, I don't think this minor surgery will dig that deep.

      Having spent a lot of time in microgravity, my main concern would be in keeping the area sterile. Dust, hair, and everything else floats around a lot better in microgravity...and keeping particulate matter out of the incision site is going to be a task. It's hard enough to keep the planes clean of the big dirt from your shoes...it doesn't take much to spread microscopic contaminants

      • If you were to blow sterile air (or argon or whatever) onto the area and remove the air through filters -- essentially establish something like a laminar flow fume hood across the site of operation -- you'd help reduce risk of contamination.

      They don't do it on ISS likely because it makes no sense. They do other medical experiments there, less risky and not so newsworthy - but probably more valuable. Like surgery on rats, for example (I remember something like that being announced some time ago.)

      TFA mentions an accident during a low spaceflight. Well, read Baxter's "Titan" for example. But if you are not suicidal enough for that, it might be enough to note that all space crews are trained in medicine; often one crewmember is a doctor, and everyone else is good enough to help.

      Another issue is that you can't compare 30-second drops and 9-minute climbs, with gravity swinging from 0 to 2G, and a quiet, stable zero gravity of a spacecraft. Who can do *anything* well in a Vomit Comet? This stunt has no value.

Peoples' organs weren't actually in the wrong place, they were being displaced by the heavy equipment, until the equipment went away again...

    I can imagine a situation where they do the operation, then land, and find that when the body of the patient settles, the stitches pull out or the organs get twisted around and he has worse problems than he would have had if they'd stayed in a relatively constant gravitational pull.

    Sure, keeping things close to the earth surface might allow for an easy abort in case of some catastrophic failure, but with the trade-off being that you'll have sharp objects in (and near) your body at constantly changing vectors and accelerations, it hardly seems worth the risk.

    While I'm sure they have a fancy plan for blood containment (small incisions and tubes for tool insertion), a slip-up at the wrong time could create some interesting situations (like a stream of small, bloody spheres all over the place). Another issue are the various other fluids to contend with, such as stomach acid, anal leakage and urine. Unless they plan to completely block off every hole on the guy (catheter, stomach pump, intibation tubes, ass plug/vacuum, etc...), this could get messy pretty quick.

    Aside from that, what ever became of ideas like one of those large rotating room to create pseudo-gravity using constant angular velocity?

So assuming this Euro "vomit comet" does 20 second weightless parabolas, there's immediately afterwards 20 seconds of TWO G, or fourty seconds of 1.5 G, or so on.
