I had one in juky w/o sedation (fentanyl only-which was a waste)....now symptoms and elevated blood tests indicate a bad situation. I moved since July and now I can't find anyone who will this colononscopy w/o sedation; one hospital agreed, I did the prep , reported this morning and the GI nurse said "sign this sedation consent" or we won't do you, no matter what you were told. The the doc (a nice lady) convinces me to change, does the pre-exam (clean but dark blood and said that was bad but that I would have to get sedation even though they that I was told it would not be required. I'm afraid that I flipped out at that point, yanked out the IV, the nurse grabbed my wrist, got stuck and I sort of left in a huff...............I know that the sedation is optional; is it more important to do these exams sedated and quickly and make more money than to take 5 minutes longer and don't use drugs that cause me severe problems? And the icing on the cake is that the doc wants me to return to have the test or "sign out AMA whatever that means and the nurse that got stuck with the needle wants me to take a blood test..............I don't think that I'll ever do this again....................
