We have it routinely stocked on all anesthesia carts, ER, cath lab, etc - anywhere anesthesia is given. To my knowledge, its never been used for verapamil od which I think is the case this guy is writing up. The bupropion case is questionable, as they pointed out.
We don't keep it in every pyxis - there are always pharmacists out there if anesthesia feels they need it on the floor.
You can push it fast if you need to - its isotonic, preferably a central line but a peripheral will work just as well. You won't find that published in the product info since anesthetic rescue I don't think is a labeled indication yet.
