Anyone out there got any helpful hints or tips to share with me about drawing labs from PICC lines when they are stubborn to give you the blood? Thanks

I have found a couple of things to help, but sometimes it just isn't going to happen...
--try having them reposition the arm...straight out beside them, above the head, etc. Do this while pt is laying down, then try with pt sitting up if needed.
--try having them cough then using different arm positions.
--have pt lay on their side
--last ditch, sometimes 1 cc of heparin put into the lumen and left for 15 minutes or so will help.

I find attempting to draw from anything less then a 4 french can collapse the lumen, and , while there is some blood return, it can still be difficult to get enough for an adequate sample.
My 'tricks' include:
1) inserting at least a #4 if I have the say in the beginning;
2) flushing vigorously with at least 20cc NS before withdrawing the waste;
3) repositioning the arm- rotating it sometimes will free the line from a trapped position between muscles;
4) having the patient take a deep breath and hold it for a few seconds, then withdrawing just as they start to exhale:
5) being sure that the patient/caregiver knows to flush the line properly, using positive pressure when clamping (seems to be frequently missed point with many of the patients I see).
