What is a Midline?
A midline is also an extended dwell catheter that, externally, looks very much like a PICC line. The largest difference between the two devices is that while a PICC ends in the large vein near the heart, a midline terminates in the extremity (arm). Although lengths vary in the PICC line, a midline usually comes premanufactured 20cm (8″) long. These do not require a chest x-ray and are ready for immediate use.
