Cardiac gtts???

Specialties MICU

Published

So...I'm a newly transferred MICU RN from a trauma unit. I have a TON of things that I have to learn, computer coorifices and all. I'm trying to also learn some of the major gtts that are used on my new floor. I have a list of the gtts that I want to learn, but am unsure of exactly what/how much I need to know for each.

For example: Levophed

Action: vasopressor - dilates coronary arteries more than twice as much as epi.

Dosage: 8-12 mcg/min initially; then adjust 2-4 mcg/min to maintain desired BP.

Assessment: check BP q2m until BP stabled then check q5m

Precautions: can casue severe tissue necrosis (blanching along vein pathway)

I have a pretty good IV drug book to get information out of, but I want to make sure that I know enough, but not too much (my brain can only hold so much into info at one time!)

Thanks in advance for any assitance! :redpinkhe

Selective beta-adrenergic receptor activation demonstrated that both beta 1- and beta 2-adrenergic receptors elicit dilation of large coronary arteries, and that the vasodilation was direct, i.e., it was not mediated by increases in coronary blood flow.
