What is Midline ?
A midline catheter is a peripheral intravenous device inserted into a vein in the upper arm, with the catheter tip positioned below the axilla and not in a central vein. It is intended for intermediate-duration therapies, typically lasting from 5 to 28 days.

Conclusion
Midline catheters offer a safe, effective option for medium-term intravenous therapy. They bridge the gap between short peripheral IVs and central lines, providing reliable access with fewer risks. When used appropriately, midlines reduce complications and improve patient comfort. Proper patient selection and skilled insertion are key to successful outcomes.
