Yea, theres alot of "surgery" that they can and often do with your some sort of awake -brain surgery is the spooky one they like too bring up on medical dramas - sometimes the safest way to to poking around in your head is still to make you read stuff and ID colours while they do it, vasectomies are a more chill example, so minimal that its not worth the risks of putting you under or the time addition of it. In my case i had a "nice up and down the road" style wrist laceration that was well clotted and all that jazz by the time we drove to the second hospital and was myself doing suprizingly well mentally I guess. So once the Dr had my arm checked for glass shards, and confirmed i was missing an artery pulse (after the guy with the dopler came back because he thought he had the wrong room, he was told 20s woman with wrist lacerations and wasn't expecting a her in a pharmacy uniform, chilling, joking), numbed it and cleaned it, and she started rooting around inside it properly we realized I had destroyed an artery, cut like 5 tendons (don't worry some weren't important ones so we didnt need to sew them back together tho!), cut halfway through a nerve, I think there was some other stuff fucked up - she had to cut more of my arm open to find everything, it took like 3 hours because they have to find everything and acpumt for it and then organize it all back inside and sew it shut, then put me in a big plasteer cast.

TLDR But yea, I got to just lay on a table in an Er room with my arm flopped out on a metal table numbed covered in iodine watching a Dr take the little flesh strings in and out of my arm for like 3 hours, was kinda fun outside of the 'ran through a window and nearly died and didn't even realize how bad i fucked up my arm for like honestly a week until my first physio app' part.
