Midline catheters are peripheral venous access devices between 3"-10" in length. Currently the most common length is approximately 8" long. This device provides an alternative to short peripheral IVs for certain treatments. While the exact length of dwell time is unknown, Midlines are routinely used for one to six weeks.
Midline catheters provide a stable, cost-effective, intermediate to long term peripheral venous access that is appropriate for acute, subacute, and home care settings. Midline catheters have also been referred to by various names including; long line, halfway, midline, extended peripheral, & peripherally inserted catheter, or PIC- not to be confused with PICC.
