Why is it important?

Midline catheters have both positive and negative implications for clinical practice. They can be used for extended periods of intravenous therapy without requiring repeated cannulations but are not without risk. Midline catheters have been associated with mechanical and chemical phlebitis along with intravascular thrombosis. As such they are not suitable across the entire adult acute population. Midline catheters reduce the number of repeated cannulations which reduces patient discomfort, increases patient satisfaction and also contributes to organisational efficiency.
