On second thoughts, the worst thing that could happen is somebody forgetting to sterilise the needle properly.
It doesnt really matter if he needs more than one attempt to stick in the needle (unlikely seeing as how its a giant honking needle and it just goes in your pelvic bone not trying to find a vein here.....) since you are under general anesthetic and cant feel a thing let alone be conscious.
