What do you do if your pt has a picc line or central line and you need to get AM labs from the line but they are on high doses of levophed or any other vasopressor? Are you supposed to put all IV fluids on hold while you draw labs so they dont dilute the lab sample.. what if your pt is very sensitive to the vasopressor and drops their pressure right away? But what if you leave the pressors on will it mess up the lab results? Please help..I need advice.

Leave your pressors running. Draw the blood from a different lumen.

yup..never turn off the pressors, even for a minute..ive seen too many BPs bottom out, quickly! If you have a lumen with nothing going to it, use that one..flush well, draw the labs then flush and clamp. If all your lumens are in use, look to see what is going into what..if they just have fluids going into one, its ok to turn those fluids off a minute to get your labs. If each lumen has a different pressor going to it, look to see if those pressors are compatible at the Y site and run them all into one lumen if compatible..that frees up a lumen.

If your patient is on high dose pressors you should have an A-line to draw labs off of period. Titrating high dose pressors without an A-line is just plain dangerous. I've titrated one low dose pressor off of a cuff before, but nothing that I felt was a high dose or anyone on more than one gtt.

And if you can't get an order for that (which has happened to me before, unfortunately), lab needs to draw directly from a vein. If you have anything running in any of the lumens, it will affect your lab results.

Exactly what i was thinking if the blood pressure is that labile on multiple drips an arterial line is essential. Don't stop the pressors.

It will indeed affect that lab results, if you can't turn all of the things running off, you need a peripheral stick or an A-line.

God no, don't interrupt your inotropes! If you've ever had an IV pump fail, you will have seen the impressive speed with which BP can plummet when inotropes are interrupted.

As per other posters, get labs from art line, different lumen, or from a peripheral stick.

Or just draw it yourself. I've found it much easier and faster. Drawing blood is easy.

However, it's just plain dangerous to not have an Aline here. I've never had a Dr say no to placing an Aline for a pt on pressors.

YOU MUST HAVE AN A-LINE! Any MD who does not say yes needs to be slapped, then call his upper to ask for an a-line. YOU MUST BE A PATIENT ADVOCATE! When the Dr. says no to an a-line when pressors are being run that is when you step up as the patient advocate and say "You are giving me an a-line!" If he can't get it on the R radius, then he needs to try the L radius, if that doesn't work, go to the R pedal, then the L pedal. Bottom line it needs to get done. Don't take no for an answer here. Now I say this because it sounds like you had multiple pressors running. And remember, anytime you access a central line/PICC, you have to stop everything running and pull up some waste. Look up your hospital's protocol on this. And always flush after getting your sample. And turn everything back on. And I'm with the others, don't turn off pressors.

Pedal? People place Alines in the feet? Did you mean femoral?

And if the doc isn't comfortable placing the a-line, in our facility, respiratory can do it with an order, and if all else fails, call anesthesia!
