Epinephrine and coronary arteries

Published

Specializes in CEN, CCRN.

Hey guys, So im familiar that epi is a potent vasoconstrictor. But does epi also constrict the coronary arteries, or do the coronaries dilate ?

And another question, pt comes in with a glucose of 25 and in Vtach, BP 74/64.. Which do you treat first? rhythem, BG, or BP? in what order?

For the Vtch, did the patient have a pulse? Looks like the patient would need a fluid bolus 20ml/kg and some Dextrose bolus. Were they seizing with a glucose that low, decreased LOC?

What was the outcome?

Treat the rhythm first. That will help correct BP. Glucose immediate second.

This is likely a homework question.

If you google it like I just did, one of the top results is a research article by the AHA that specifically discusses that question. So you tell me!

Do they have a pulse and what is the heart rate? All 3 would get treated nearly simultaneously, if pulseless VT: compressions, start dumping in fluids, and D50, or glucagon if no IV access.

Patients can have a pulse with VT, especially if it is in the low 100s. You have to prime the pump and give it some fuel if you want it to work right.

And I found that AHA article very interesting!

I was in a patient's room with 3 doctors in a tricky situation trying to find a solution the other night and the surgeon, who is very well respected and highly regarded piped in and said "have you tried googling it? I do it all the time when I'm stuck".

The Internet is a plethora of information. Obviously you need to use legitimate sources (such as the AHA source mentioned above) and not just any random website... But don't judge someone for using their resources. The Internet can be your best friend if used appropriately.

PS: Google led us to a solution.
