I don't know. At my current hospital workplace, and the hospital where I receive my care, it's Propofol that's the drug of choice, and I totally prefer it. Rarely have I received the Fentanyl/Versed mix, though it's still used. But there's pushes to get away from benzodiazepines.
Propofol is is metabolized and out of your system in minutes after it's turned off. No hung-over feeling with it, too.
We also use a med called Precedex often, too, though less with conscious sedation and more for short term (24-48 hours) in the ICU.
