I would like to clear up some misinformed staff and lab personal on protocol for lab draws from PICCs/Ports. When a pt has a heparin drip or TPN infusing through a single lumen chest port or PICC, I have heard staff from lab or nurses seem to think the IV has to be turned off for 10-15 min before drawing labs. I realize drawing a peripheral stick is preferred but sometimes this is not a option for a pt. with poor IV access. I don't think staff is aware of the blood flow per minute through the SVC. Could you please address this or provide current articles that I could site to help lab staff and nurses become more familiar with proper protocol.
Thanks so much,
