Epinephrine and coronary arteries

Published

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?

Sheesh, I feel bad for your patients lol well I know its a peripheral vasopressor but I'm asking about the caronaries .

Yes, the article is specifically about the coronaries. Don't feel bad for my patients though, the babies don't usually ask me about that stuff.

It took less than 30 seconds for me to find a written answer to your question just using Google. Why can't you do the same?

So why are we arguing about a pulse when they have a measurable blood pressure? No pulse means no blood pressure. Still book answer is treat the fatal arrhythmia. Real world do it all at once.

Yeah epi, increases HR/BP and contraction. But dilate the coronaries for more o2 delivery. Thank you

You feel bad for Julius Seizure's patients, yet you're perseverating on AN?

I didn't read the article so maybe my answer will be different. Ultimately, I think you're asking the wrong question. It should be "what does epinephrine do to coronary artery flow", be cause whatever it does to the vessel itself (dilate, constrict) it doesn't matter. What matters is the amount of blood moving through them.

So...the answer to the question that you did not ask is: epinephrine increases coronary artery flow. Beyond that, nothing else matters.
