A midline catheter is a type of vascular access device designed for placement into a peripheral vein, usually in the arm. It is different from a central venous catheter (CVC) as it does not reach as far into the venous system. The tip of a midline catheter is typically positioned in a deep peripheral vein, often the axillary vein.
Here are key features and aspects of midline catheters:
Placement: It is inserted into a peripheral vein, offering an alternative to central venous catheters like PICCs.
Length of Dwell: Midline catheters have a longer dwell time compared to short peripheral catheters, often up to 6 weeks.
Purpose: They are used for intravenous therapies that require longer access duration but do not necessitate the use of a central line.
Advantages: Midlines provide advantages over traditional cannulas, offering a compromise between peripheral and central venous access.
It’s crucial to note that while midline catheters offer benefits, they also come with considerations regarding appropriate use and potential complications. Healthcare professionals evaluate patient needs and medical requirements to determine the most suitable vascular access device.
