When I severely dislocated my shoulder the hospital sedated me with ketamine and propofal. They'd already given me the max dosage of morphine and fentanyl to get me to be able to barely sit up for an X-ray.

So I'd say it's used in humans for anesthetic too.

And guys, I'd the doc says after your first dislocation you should have the surgery to prevent it from happening again, you should listen to them so you don't spend a night in excruciating pain three months later.

For what it's worth, when I came too I felt like I was black out drunk, not a good experience for a previous alcoholic
