Colonoscopy & Conscious Sedation

I had a couple of colonoscopies back in the early 1990s when I was having some sort of inflamatory bowel problem. Even with sedation they were EXCRUCIATING! They hurt so bad they could not be completed. The second time I screamed so much, they increased whatever sedation/pain med to the point that I stopped breathing. I know that happened because the pain went away, then started to come back as someone was telling me to breathe.

As a result, I have not had another one although I should probably do so.

I should have asked what medications they were giving me in the IV because I have been told now that my records were destroyed after 7 years. After doing some reading, I suspect I had a "paradoxical reaction" to the seditive.

Anyone remember what were the seditive and pain drugs of choice used back from about 1991 to 1995? If I have to have another procedure, I don't want the same seditive!

In the last couple years I've developed high blood pressure, controlled by tiazac (diltiazem), a calcium channe blocker. Seems that does not go well with fentanyl, so they should not use that on me nowdays anyway.

I would most certainly use anesthesia, my only question is which one would work on me, since what I had in the early 1990s did not work. "Conscious sedation" was conscious alright but not sedating. I remember the whole painful event.

Does propofol put you out completely?
