Surgical Tech here. OR scenes are pretty comical. Order of, or even complete absence of head cover / mask in relation to hand scrub. Touching shit that isn't on the sterile field. Using the wrong instruments. Leaving during an inappropriate part of the case.

The intro of the Dr Strange movie comes to mind - iirc they have masks initially, but they just disappear mid-operation, then he fishes a bullet out of the brain with a pituitary rongeur, everybody oohs and aahs and then he just leaves lol. He must have a really good tech if he expects them to close the dura, repair the skull, and close the scalp, not to mention cutting/drilling through all that shit to get initial access in the first place.

...and it's hailed as one of the better OR scenes, lol.
