Lining and labs/ hemolyzed specimens

Specialties Emergency

Published

So it was decided by our hospital that it is no longer "acceptable" to draw labs when starting an IV--i.e. they have to be peripherally stuck for blood in addition to the stick for the IV start. The supposed reasoning behind this is that too many blood specimens were hemolyzed when drawn during an IV start, especially compared with the hemolysis rate for phlebotomists drawing on the floor.

So, we were 'provided' with a phlebotomist and it apparently showed or hemolysis rate went down when they drew blood. What I find interesting is that they were doing such a great job that, yet they went from working in the ER from 11a-11p to now just working 11a-7p. In addition, we are the first place from which a phlebotomist is pulled if they are short staffed (so that they cover the whole house). A coworker also make an interesting observation. When the phlebotomist draws blood they send it to the lab in a colored biohazard bag, while the biohazard bag that we have in stock is clear plastic with the biohazard logo on it. The coworker suggested that if the specimen shows up in the colored bag, the lab treats it differently so that it does not come back hemolyzed or the ignore minor hemolysis on these specimens, yet they always report even the smallest amount of hemolysis drawn on samples drawn by ER staff. Not sure if I buy into the conspiracy theory, but it is an interesting thought.

I have been told by several ER docs and residents that this is a foolish policy and that they line/lab (all in one stick) "everywhere." One doc, who happens to run the residency program for the hospital system asked me "who came up with such an inane policy?"

Anyway, just looking for comments from other ER nurses. Anyone else have to deal with something so silly?

After all this, promptly send the samples to the lab, and there should be no problem.

Well, that is assuming the lab processes the received sample right away...and we all know what happens when you assume.

I just get upset when they tell me all my tubes need redrawn. Especially when the poor pt was such a hard poke.

I can usually tell when it came out waaaay to fast or slow, but I have a hard time believing sometimes that every tube was bad. Call me back and tell me a color ;)

In my opinion it depends on who is working in the lab as far as how many times we get the call that the blood is hemolyzed. So lets say they do call and say it is. We go back in stick the patient again, send it to the lab and guess what? It's hemolyzed again. I've gotten where I just keep extra tubes when I start an IV and send them up if they do call, most of the time, they aren't hemolyzed. Depending on where you work and the labs policies you can use pedi tubes which seem to not be as bad to me.

Oh yeah and sometimes I just pop the top off the tube and let the blood just flow into the tube with no suction at all. I do this if I'm in a vein but can't get the catheter to advance but it has great blood return and the vein isn't blowing.

Be careful with this practice as the vacuum on certain colors of tubes is set to allow a certain volume of blood into the tube to mix with the additive in a specific ratio. If that tube is over or under filled your labs will be off and will have to be repeated.

I'm not an ER nurse, but I think I can give some perspective here. Before becoming an RN, I was a lab tech. You know, the one who actually runs the tests. I think every hospital has a communication barrier between lab and nursing, and it can be difficult to understand exactly why it is the way it is.

First, as for not having enough blood to run a test, it most certainly has nothing to do with the lab staff. Certain machines need certain amounts of blood. If the machine rejects the specimen, it can not be "made" to run the test. Depending on the test, the lab tech might be able to run it manually, which takes a LOT longer, and if there wasn't enough for the machine, you're not likely to get very accurate results manually either.

10mls of blood for a culture provides the most accurate results. If the patient is able to give up that much, they should. Just because other cultures have shown positive with less specimen doesn't mean that all cultures will show up with less. If your lab tech is sick to death of fighting with the nursing staff, or the patient is too young to give up all that blood, they can do the test, but again, less accurate.

It would be a pretty twisted lab tech who would treat specimens drawn by nursing any differently than ones the phlebotomist drew. Also, leaving a CBC sit for a few hours will not cause it to hemolyze. CBCs can be done off of blood up to 48 hours old in either a lavender or green tube, depending on the instrument doing it.

I've never met a lab tech who really wants to have a patient restuck. Yes, I worked with some nasty people, but no one who ever tried to punish nurses by tormenting patients. We in the lab didn't want to make those phone calls any more than the units wanted to hear from us. Being on the other side, I can see how it is a frustrating system to everyone involved.

I have to say that I have seen cases where this is not true. There has been times where the blood is a half a micron below the line on a light blue (coag) tube and I have gotten called saying they could not run the test. There was another time I was helping another nurse with a difficult stick....she only got the tube half full, removed the tube from the line and said "that'll do." Well, lab ran it. So, something has to be going on...

Why not just have a policy to do a peripheral stick in the case of a hemolyzed specimen from a line draw? I am sure PG doesn't really measure the increased satisfaction that would provide as most patients do not even know it is an option.

Because waiting a second time for a K level to be run means another 25 minutes in LOS. :eek: Welcome to the silliness of being timed on everything!

That truly sucks. You have my sympathies!

Eh, that's life...but it does get annoying.

Per our department policy, our lab techs/phleebs are supposed to do all lab draws on our patients separate from nurses starting IV sites in order to reduce hemolysis of specimens. I'm kind of ambivalent on this policy as a new nurse probably mostly due to my inexperience. I haven't had a lot of patient complaints and there seems (anecdotally) to be a low rate of re-draws due to poor specimens. The only time this policy is rescinded is in the case of peds and hard sticks. The first time I got an excellent vein in a hard stick pt. the lab tech was right next to me handing me adapters, vacutainers and tubes and telling me what to draw as I'm holding the catheter in trying not to lose the site. I admit I wasn't totally prepared for being asked to draw labs once I finally got a good bleeder. But it all turned out all right in that case with all the tubes/cultures done AND a patent, useable site.
