The INS standard that addresses Midlines and blood drawing is #37, Under practice Criterial II, Item H--"Midline catheters should not be used routinely for blood drawing"
Chris Cavanaugh, RN, BSN, CRNI, VA-BC
And this INS standard is based on the fact that there are no studies or reports of any kind about the success or failure of drawing blood samples from a mildine catheter. A midline tip location is still within a peripheral vein where the blood flow and vein diameter is much smaller than the SVC. There could be an additional risk for vein irriation with frequent blood draws, but we simply do not have any studies on this issue at all. Lynn

We do use midline catheters routinely for drawing blood and have not had any issues.
