True, that. From their perspective, the OS and anesthesiologist who have a preference (and I'm sure most do) will have based that on how well their patients do, and presumably have done various operations with both methods and HAVE therefore based their preference on that comparison. At least one would hope so. I wasnt offered the option of a general and it would never have occurred to me for ask for it, based on how well my husband did with his spinal--we did have to struggle with him to get him awake and to the john to pee after his hernia repair so he could go home, but that was due to them having to slug him with extra sedation during the op, nothing to do with the spinal end of things. Personally, I would never want to be intubated if it could be avoided.
A zillion years ago when I was in nursing school the big drawback to spinals, if I recall correctly, was patients having to lay flat for a very long time to prevent the dreaded "spinal headache." Or perhaps that was just for aspiration of spinal fluid, I dunno. At any rate, when I woke up post op I was semi sitting and my punkin' head felt just fine. Drowsy but certainly not hurting.
