Medication 2
Fentanyl / Midazolam for colonoscopy sedation is pretty common here in the US according to the Dr. who did mine, especially on the West Coast. Propofol, which used to be the drug of choice, is falling into disuse because it requires the presence of an anesthesiologist. Under the FM sedation I was never fully out, I don't think, although in the recovery room (about 90 min) I dozed off. Immediately after the procedure I doubt I could have stood up.
I can't find any reference to the F/M mix being used during a cardiac "stress test". Something about the story doesn't quite add up in my mind, but I'm not a Dr.
