What is the primary advantage of using midline catheters?

The primary advantage of using midline catheters lies in their design and intended use, which promotes increased patient comfort. Midline catheters are inserted into the peripheral veins and extend to a location near the shoulder, providing an effective alternative for patients who require an intermediate solution between peripheral and central venous access.

While midline catheters can be more comfortable for patients compared to central catheters, they are not typically designed for long-term use like some central lines, which can remain in place for months. Infections associated with midline catheters do occur, but they are similar to peripheral catheters and not necessarily less likely, particularly since they are still exposed to the vascular system. Their primary purpose is not to provide both peripheral and central access; rather, they serve a specific role as an alternative access point that bridges some of the benefits of both types.

Thus, the emphasis on patient comfort is critical, especially for those requiring repeated vascular access over time, making this aspect the key reason for using midline catheters.
