"Fetch me one of those thingamajigs
with the red and black marking tape"
It's not too hard to figure out the marking behavior of dogs, cats and bears, but to find the motivation for
I guess this is a convoluted way of saying you cannot tell what something is just by looking at it or using it. It's not all that difficult to learn the nomenclature of surgical instruments and have a general idea of how the instrument is used. A Penfield is a Penfield because that's what it is. The black and red tape is not what gives an instrument it's identity. So the instrument is the instrument, ineffable, a well defined entity completely independent of the strips of colored tape applied on the whim of an administrative wisenheimer. If you are working in the perioperative arena and don't know the identity of your instruments, the only steak you should be holding is a T-bone.
"We mark our instruments so as to organize them into sets for a specific case. Green/black markings mean the instrument is part of the fem-pop bypass tray," said nursing supervisor, Mary Marks-a-Lot
This is wrong headed thinking of the highest order. The surgery determines the type of instrument used not the instrument determining the surgery. The tail is wagging the dog with case specific instrument trays and the circulating nurse will be running like a whippet to the nearest autoclave to flash sterilize the instruments you really need for unexpected circumstances. I often fantasized about instrument marking misfits standing directly in front of the autoclave when I suddenly cracked the door after a flash sterilization cycle. Maybe a blast of scalding steam to their sensory regions would bring them to their senses.
Instruments used in case specific trays are also more subject to wear and tear because they are used in the same manner time after time. For maximum instrument life it's best to use them on a rotating basis with different cases through varying services. Auto mechanics don't have a breaker bar just for working on struts - they use it wherever it's needed. Surgical instruments should be used as needed and not assigned to a case specific use.
Scrub nurses have enough to keep track of; sponges, needles, and instruments. an additional duty of inspecting each instrument for loose or missing tape is stretching the limit. ID tape is just one more unnecessary worry for a harried nurse.
Microorganisms are crafty little devils and I suspect they could use the ID markings as a sort of shield to escape the unpleasant effects of gas or heat sterilization. I always suspected that tape margin where it interfaces with the instrument surface as an area for assorted biomass crud build-up. Instruments just look cleaner without identification tape.
I usually tried to avoid pharmaceutical reps and medical equipment sales people like the plague. The very reserved German fellow that represented VMueller instruments was a source of information and a true expert on the care and feeding of surgical instruments. He summed up my feelings perfectly when he surveyed an instrument tray with ID tapes plastered on his beautiful product, "Dumkopfs!" he hollered followed by some German cuss words He did not have to explain who or what he was referring to while I nodded my head in somber agreement.
