Do I have to flush before withdrawing a blood from a PICC even a 0.9 Nacl + k running
- 0Sep 25, '12 by mspurpleI did not practice nursing for almost 4 yrs, and just started working again as nurse 2 days ago ) it's my first time to draw blood from a picc, just wondering, if there is an IV running through the PICC like 0.9% NaCl + K 40 mmol do I have to flush before withdraw a blood?

1 Stop all infusions going through ALL lumens of the PICC or CVC for at least one FULL minute
2. Scrub the needless connector for 15 seconds with IPA (alcohol)
3. Verify patency of the selected lumen ( On a PICC select largest lumen if that applies as draw will be a bit faster but anything can be used)
4. Discard at least 2 x the priming volume of the line (5- 8 ml is adequate for a PICC). Look at the discard and you can see the first part will appear a bit dilute and you can tell when it gets darker and you have no NS in that section of the syringe
5. withdraw your sample using a syringe (s), A 10 ml syringe works the best and draw slowly and consistently. Do not pull so hard that it vibrates b/c you will hemolyze the cells and then the results cannot be trusted. Do not use a vacutainer on a PICC.
6 Transfer the specimen into specimen tubes using a transfer device.Do not force the blood in.. let it fill on its own. May lab tubes now have a safety feature that does not allow the blood to drip or spray if used incorrectly.
7 Immediately flush the PICC with at least 10-20 ml NS and if locked with heparin flush if your facility is still using it. Improper flushing after a blood draw is a common cause of catheter occlusion
8. Make certain caps are clean and no bloody
9. label blood specimens at the bedside.
- 0Oct 6, '12 by Quit Floating MeQuote from threebrats46The same reason you are not supposed to use a syringe smaller than 10ml. Vacutainers cause a large increase in pressure in the lumen(s). Also, the other day I was looking at the standard orders for PICC line maintenance and it says in bold lettering NO VACUTAINERS.We always use vacutainers on PICCs,what is the reasoning behind the advice of not to?
- 0Oct 6, '12 by MunoRNPlease don't waste 10cc of blood out of a PICC. The waste should be 2 to no more than 3 times the priming volume. A Power lumen on a PICC has a volume of 1.7mls, groshong lumens are about half that, 3 times 1.7 mls is 5.1 mls. It's the patient's blood, not ours, please don't throw it in the trash without a good reason.
