I actually watched this entire debate (about 1.5 hours), and I felt like Dr. Cox did an excellent job explaining things in a way everyone could understand. I also don't remember him saying anything about injections "into" the spinal cord.
The funniest thing to me is the opposition claiming that this is the bill that will "kill rural Oklahoma." Currently there are only 2 hospitals in the entire state letting CRNA's do the procedures that this bill would prohibit, with (I think) a total of 5 individuals actually doing them. Yet somehow, they make it sound as if it's going to prevent folks in rural areas all over the state from getting any sort of medical care whatsoever.
"If you have boots, you better vote against it." Hilarious and sad at the same time...
