Dilantin/Phenytoin Question

Have you ever given Dilantin IV push? How fast do you give it and what's the usual dose you give? Does the patient need any extra monitoring? Any precautions other than the standard Don't mix with D5 rule?

I ask because I usually give Dilantin as an infusion, not a push. (And way more Cerebyx than Dilantin.) Also, this was not my patient. The dose was 300 mg and came in 100 mg vials, so there were 3 vials.

I'm just curious. If it was my patient, I probably would've called Pharmacy and if I had to push over 100 mg, I'd most likely have asked for an infusion to be made up. (Remembering that I deal with mostly elderly cardiac patients.)

But maybe I'm all wet with that idea, so I'd be happy to learn more about this.
