The stories they could tell
Apparently what's said in the operating room stays in the operating room.
How else would you account for the fact you never hear doctors and nurses telling stories about the drug-induced goofy stuff patients say both before and after a surgical procedure? I happen to know some of those loopy utterances are pretty hilarious.
Perhaps it's professionalism and ethics that keeps these folks from blabbing. Or maybe they just keep the stories to themselves.
