We've been doing LISA/MIST for a few years now, but there is still no clear guideline in our hospital concerning premedication. Almost every attending and fellow uses some sort of narcotic, though everybody uses different medication, and some use no premedication at all (most of the time). I'm wondering, does anybody use Propofol for LISA/MIST currently? If so, what is your experience with it? Which dosage do you use?
