the medical center i'm at was part of the trial. in talking to folks who used it, it was great. incidentally, they also tried it with vecuronium with same great results ( though im pretty sure they were breaking the rules by doing this since organon, the makers of sugammadex, also make rocuronium and therefore would prefer sugammadex be used exclusively with roc, boosting sales). though rocuronium has faster onset, from what i understand, vecuronium has lower incidence of alergic reactions.
