I am rather new to allnurses.com, but I may be able to shed some light here I hope. I have had this kind of sedation recently at my oral surgeon. To be honest, I have had 3 times with him. If I am not mistaken, a CRNA is the one who in charge of the administration of whatever they gave me to knock me out. But I do know of one visit where my oral surgeon administered the drugs himself. Each time, they had me positioned where I could not see my IV, or anyone was injecting anything into it. What makes me say the doctor himself administered it once is because he was nice enough to tell me just before he started the anesthesia, and after the administration he said something to the effect of "now, lets let that cook for a moment". I know that is an odd thing for a doctor to say, but I had asked them to take things slowly with me because of some bad experiences I had when I was younger.
Is there anyway to know which drugs they used on me without asking them? I dont want to sound silly asking them what drugs they use. I dont know if this information would help, but in my opinion it took about 20 to 30 seconds for the anesthesia to take effect. I know the time may be off because those drugs alter one's perception. The anesthesia took effect gradually, but not bad at all. At first i just felt very much relaxed, then I noticed my eyes started to want to roll back in my head. Finally, I remember my vision going blurry, and then out I went.
One reason I had a bad experience when I was younger I believe is because the anesthesia (general anesthesia for eye operations) took effect extremely quickly and I could not breathe before being completely asleep. That is why, I asked my oral surgeon to take his time. I also told him of my fears and bad experiences too. I think he made a note of it of in my file because since then all the nurses have been extraodinarily kind and careing. That in and of itself has been a tremendous help. I will be going back to my oral surgeon again to get some more work done in preparation for a denture. I have bad teeth as a result of bad genes and bad childhood habits.
Sorry for the long winded post, but I really hope my information helps, and I can get some insight from everyone here.
