Probably a vacutainer adaptor.

Subject: Re: Vancomycin lab draws
This article should help. I am not aware of anything
since this was published:
1.
Frey, A., Drawing blood from vascular access devices: Evidence-based
practice. Journal of Infusion Nursing, 2003. 26(5): p. 285-295.
I am not sure I understand what you are saying about
the blood drawing with a blunt cannula. How can they puncture the rubber
stopper on the top of a vacuum tube with a blunt cannula? I was not aware that
this was possible because the stopper is not pre-slit to accept the cannula.
There are devices designed specifically for the purpose of transferring blood
from a syringe to a vacuum tube without a needle. Are they not using one of
these devices? Lynn

Hi everyone,
I have a couple of questions for the
group. I work for a LTC pharmacy and a couple of issues associated with lab
draws came up at an in-service lately.
·
When drawing vancomycin trough levels through a PICC
line, are there concerns about the accuracy of the vanco trough if it is
drawn through the same lumen as it is infused through? If you are drawing
through the same lumen, what is the discard? 10 ml?

Also one of our homes is using syringes with a blunt
cannula to draw and transfer blood to the lab tubes. The cannula twists
off (luer connector) for the draw and they re-attach it and access the tube
with the blunt cannula. The blood will transfer without pressing on the
plunger. It seems to work okay in that it is "needleless"
without splashes. Am I missing something?

Thank you all in advance
