take it from someone who works with and sterilizes surgical instruments for a living.
alcohol aint worth shit, but it does have significant usefulness in the cleaning process.
true sterility is very difficult to achieve, and even with autoclaves there are risks of spores and moisture in packs.
our autoclaves run a very specific cycle that threatens the vegetative bacteria, to induce spore formation.
it backs off, allowing them to become vulnerable, and then repeats the process, successively.
i could also tell you stories of surgeons using contaminated instruments that would make the hairs on the back of your neck stand up.
being a phd candidate/doctor doesn’t mean shit to me. i’ve seen firsthand how careless and thoughtless they can be about common sense shit with sterile fields and such.
generally, that’s what scrubs are in there for. and most surgeons are generally pretty on the ball - they have to be. but man, sometimes…
Yeah i just knew basic stuff from when I used to hang around his shop a lot when i was little. I dont know all the specifics but basically my point was what you said. If you clean medical equipment, it HAS to go farther than just alcohol. If you take needles and only clean them with alcohol, you might as well just wipe it down with your shirt and call it a day. I dont know what kind of autoclave my dad has at the shop, since i havent been there in a while and i think the last one had to get replaced, but im not sure if it does some of the stuff you mentioned. I just know he has a small one used only for sterilizing piercing needles, tattoo equipment and some piercing jewelry i believe.
And yeah surgeons being idiots is common knowledge. But not just about sterile fields and such things, just general shit. I didnt find out until later, but the guy who essentially put my left shoulder back together, was an alcoholic and was on painkillers during not only mine, but multiple surgeries. I missed out on the lawsuit against him though. My shoulder still isnt really even 100% 5 years later. But if some can cut somebody open while high as fuck, it doesnt surprise me that some others would go “No dude this scalpel only has a LITTLE BIT of green on it. Its fine man.”
Because EVERY teenager is an irresponsible dumbass am I right.
You can’t write off teenagers just for being teenagers. They’re at the age where they should be expected to be obedient, responsible, and commutative. If some of them can’t then too bad.
Your dad probably has something like a flash pan, plenty good enough for his needs. It’s less thorough than a full autoclave, but it will kill virtually any organism you’re likely to encounter at a tattoo shop.
Obviously in the OR, we have to get real thorough because we see some pretty nasty and hardy microorganisms. We also do implants, and each implant we load up, we throw in a tube of thermophilic (heat loving) bacteria that are notoriously hard to kill in an autoclave (always challenging the system). We put another tube of the same bacteria into an incubator as a control. When the load is finished in the autoclave, we’ll put the bacteria from that load into an incubator to see if it grows.
If even a single organism survived, growth will occur, and it will come up as a positive test and we have to shut down the 'clave and figure out what’s wrong. Obviously we don’t use any of the instruments that were in that load. Haven’t seen that happen yet, thankfully, because it would be a huge ordeal.
There are multiple stages of control and safety, because when you cut someone open and start groping inside their thoracic cavity, you are bypassing all the immune system barriers and delivering contaminants right to critical, vulnerable organs. Especially with an implant like a screw or a plate; thousands die every year from complications related to perioperative, nosocomial infections (ie, they got infected via surgery).
Even with all of this, it’s still extremely difficult to guarantee sterility. We can kill every organism except prions; those won’t even be destroyed by steam, it requires denaturing the prion itself via complete oxidation. Ie, you gotta incinerate that shit. Anything used that might have been on a case with someone having BSE or CJD, gets tossed. anything and everything, no matter how expensive.
One time an ortho surgeon was in there for a case.
The scrub was assembling one of the bone drills and as she pushed a rod through the cannulated hole, little flakes of dried bone and blood sprayed out the other end, contaminating the entire field.
Tension spiked in the room.
The doc shrugged, ‘it’s sterile blood, right?’ and carried on with the procedure. And that’s the sort of thinking a lot of docs have. They aren’t experts in this particular field because they don’t need to be; and that’s fair - but it leads to a lot of heated words now and then between us and the surgeons.
stories like that happen more often than you think.
my HS biology teacher told us about this experiment. some kid found out he was adopted when his blood type didn’t match that of his parents. anyway they stopped allowing it in the late 90s for fear of HIV, at least in california.
