You can talk to your surgeon and anesthesiologist about your request. I have heard of people waking up in the middle of hip surgery (though the spinal was still in effect, so they felt nothing). My brother woke up in the middle of knee replacement surgery. He said he was freaked by seeing the surgeon's hammer coming at his leg. He turned it into a humorous story. Haven't heard of many people requesting this.
So it sounds like you want a spinal ... and no sedation? ... As someone who woke up during surgery once said, it'll sound like an autobody shop in there. Saws, hammering, all of that. You want to be awake for that? You won't feel anything, but most people don't want to hear what's going on.
Talk to your surgeon about this.
