Surgical Tools to Include RFID 272

    I have a better idea.

    Before closing a patient, doctors would wave a receiver over the body to look for the chips which would indicate that something was left inside.

    The timing would be a little better, don't you think?

    • Why not just implant the receiver wand inside the patient? Then you can wave the scalpels over it. Or something.
      • Why use RFID at all, since it doesn't matter which particular surgical implement was left behind. How about a simple metal detector? It wouldn't catch some things, like sponges, but if they can put an RFID chip on there, why not a (cheaper) stainless steel bb embedded in the sponge?
        • Because of the very logic you impose. Besides, this also allows for:

          1. Inventory before surgery, to be sure that all necessary parts for surgery are present
          2. Inventory after surgery, to be sure that nothing is left in patient, and that all objects are accounted for
          3. Generic inventory tracking of materials.
          4. Alerts when inventory "walks" out of the hospital

      You'd think; however, the doctor needs tools to close you back up. If one of these tools is lost during the process and after the check, we're back to the same problem.

      • Good point!

        Perhaps a check at both points would be in order.

        • The first check would be redundant then, and the process probably already includes a visual check.

          • The first check would not be redundant because it still provides a chance to find an instrument without having to reopen the patient. Of course you have a visual check, but it can miss things--obviously, since instruments are left in patients.

Lots of nooks and crannies small items can slip into, also the whole thing is constantly on the move due to the contractions of the digestive organs, beathing and certainly due to the doctors operating and mocing things around. Add a certain amount of blood and bloody water (you flush surfaces both to keep them from drying out (bad for the tissue) and to keep a clear field of vision. Add several hours of operating time for large operations and there is a clear risk to lose things inside the patient. A professional operating team will take several security measures to keep this from happening (see my other post in this thread), but there still is a considerable riskm even without haste and neglect (yes, I am a MD by training).

        Maybe, but it's done. The last surgery I watched (my wife's C-section) they were extremely meticulous about sponges in versus sponges out. They double-checked the count of the number of packs-of-10 sponges in the room at the start, there was one person who it appeard had the sole duty of counting used sponges and putting them in little plastic strips with 10 sponge-sized pouches per strip. Then someone else double-checked that count. Then before they closed, they counted the number of unopened packs and added the number of plastic strips, and made sure it was the same as the number they started out with. It seemed like a very well-thought-out way of avoiding that exact problem.

        Actually, as far as uses of RFID go, this seems like a fairly good one. The incremental cost of adding RFID to surgical instruments is trivial, you aren't working against a dedicated attacker trying to subvert your system, and although the number of instances of instruments left in patients is fairly low, this system, I would think, would probably cost-justify itself given the cost-per-incident-avoided.

    and it wouldn't be that hard to add a bit of steel to the sponges.

    The same technology they should be using at the MRI machine.

    Is this the new way to force us to read the article...make the headline/summary inaccurate or misleading??

    I guess sponge is a tool in the broadest sense, but they really talk about sponges. I was thinking instruments. Trying to guess how the hospital could imbed anything into stainless steel, hehe.

    Makes more sense as the sponges are the item that needs it most. Needles and blades usually get put on a magnetic card with numbered slots. If you opened 6 there should be 6 used on card/box before you toss it ;)

    Hey

    Let me give you a quick summary of procedure in an operating room, as regards instruments and instrument counts:

    Every surgeon has a card (usually, literally a 3"x5" index card) with preferences and requirements for each particular operation they perform: for an appendectomy they may need a Saxony brand defrobulator and a #10 blade as the specialized items and they like to close the bowel with 2-0 (aka 00) chromic (made from catgut) and they like to close the skin with 3-0 poly and 6-0 purebread (usually used in cataract / ophthalmic procedures, but hey Underdog spoke out to me.) There might be three each of any particular scalpel blade they need and howsoever much of those stitches threaded on the appropriate types of needles: curved, straight, cutting, non-cutting, etc. There will also be the appropriate number of hemostats, deblooduclips, etc, that are necessary for the procedure. For a different procedure, say a vasectomy,... okay, let's say cranial burr hole or craniotomy for decompression of subdural for all the guys wincing out there, they may want a hand-twist drill, plastic clips for holding the scalp edges, good thick chromic for the fascial closure, etc., so a different set of objects.

    There will be a minimum of two nurses assisting with the procedure, a scrub nurse (scrubbed in to the operation, hence the name) and a circulating nurse. The circulator will make sure that the tray with all of the equipment is already there before the operation starts. Even before the surgeon scrubs in, the scrub nurse will also go over the instruments and objects and de a pre-op count: making sure that there is enough of every item and making a note of the number of objects, including sponges which are actually small pieces of cloth uses to sponge up that red stuff that leaks out humans when they're cut. These cloths usually have a radio-opaque fiber sewn into them so that when they're accidentally left in the human body, something is easily apparent on X-ray or C-T; cotton is not so opaque to x-radiation.

    The nurses know that there are int counts[i] of char* objects[i] for each of the different objects. The preop counts array is usually written on the form the circ nurse fills out. Then all of the really good fun stuff
    happens, and as it is almost all done and the surgeon is getting ready to close, the scrub nurse starts a pre-close count: counts that the number of needles handed back by the surgeon plus the number of unused needles adds up to the number that was in the pre-op count (for each variety of pre-threaded needle). They also check that the number of clean unused sponges (whether 1"x1", 2"x2", 0.5"x0.5", etc) added to the number of blooded sponges handed back by the surgeon off of the surgical field also add up to the number expected. All of the other instruments: retractors, hemostats, bolt-cutters (used to cut the titanium bars in the fun ortho cases), machetes (used in amputations...), are also counted to make sure none are missing. (sometimes, even retractors fall into the morbidly obese and are missed.)

    If the pre-op count is not correct, there is a frenzy as the doc looks inside the patient (or, if the closing is happening real fast, the doc says find it find it and the nurses run around checking the little bits on the floor and mopping up with surgical cloths to see if a needle fell onto the floor or onto the surgeons' or nurses' gowns or even if the needle is stuck onto the bottom of the little blue booties the OR personnel are using to cover their hospital footwear.)

    If the count is correct, then the closing is done, and then the scrub nurse does ANOTHER final post-op count and rewrites it all down to make sure nothing was left behind.

    Amazingly, even in cases where stuff was left behind, the written records usually show that the count was correct: someone takes a shortcut and writes a copy of the list and it often isn't until the patient has an infection or a recurrent problems days, weeks, months, years down the r
