hi, I don't know if it's the same thing, I got referred by my dentist to hospital. I had to have 11 teeth taken out and I was so stressed about it and worried about the pain, that was the reason for the referral. I was given an injection via a cannula (can't really remember the name of the drug, think it may have been metronidazole), I didn't know it had even been done, then 20 min later it was finished. I don't remember a thing about it, which is good.
I hope it goes okay for you.
