- Aug 27, '07 by Emmanuel GoldsteinOur policy for blood draws from a PICC was to stop any IVF infusing, flush the lines with 10cc of saline, withdraw a waste, withdraw the sample, then flush with 20cc of saline before starting the fluids again. If TPN was infusing, we flushed with 20cc of saline beforehand. When I left, they were re-writing the policy to delete the step of flushing prior to the waste.

- Nov 4, '10 by blondy2061hSome of our patients get q2h blood draws. I would never get the TPN in if I stopped it for 30 minutes every time I needed to draw blood, and my patients' blood sugars would be a mess. The whole point of stopping, clamping, and drawing a waste is that you're getting their blood, not what's infusing.

Flush with 10 cc NS, waste, draw sample and flush with 20 cc NSLast edit by RaeRN30 on Nov 4, '10 : Reason: Oops
- Feb 18, '11 by annisterStop TPN, flush and clamp lumen
Flush 2nd lumen with 10ml
Flush again with 10ml
Unclamp and resume TPN
- Sep 30, '11 by derbTPN must always run through a dedicated port. The TPN should be stopped for a minute. Flush the other lumen with 10cc of saline and confirm blood flow with your flush syringe and actually draw your 10cc waste back in that same syringe. Draw your sample and flush well with 20cc of saline.
- Sep 30, '11 by SweetheartRNI would basically do what annister did.
1) Stop and cap TPN or pause and clamp tubing.
2) Clean both ports. Flush both ports with 10 cc syringe
3) On port that wasn't being used for TPN withdraw waste (10 cc).
4) Draw labs.
5) Flush with 10 cc syringe or 20cc (there is no protocol for which on my floor)
6) Restart TPN.
- Sep 30, '11 by DugledeeI use to think we stopped TPN for 30 minutes until I read hospital policy on this a week ago. I understand all hospital policies are different. Ours states to stop TPN for 5 minutes. Flush all ports with 10 ml NS. Draw 10ml waste. Draw blood with empty 10 ml syringe and transfer device. We then flush every port with 2- 10 cc NS syringes in a pulsating motion. We always leave 1 ml of NS in the last flush for a total of 19 cc's per port. I had a patient going into fluid overload last week on TPN,Lipids,and NS. I called the doc to get orders. Our policy states to never stop TPN abruptly and if you do so then to hang d10 at the same rate as the TPN and monitor for hypoglycemia. Not sure if that is the same everywhere. I just wonder how long TPN can be stopped before d10 needs to be hung.
