Midline catheters and central venous catheters (CVCs) are both medical devices used for intravenous access, but they have distinct differences in their design and application.
Understanding these differences is crucial for healthcare professionals to make informed decisions regarding catheter selection and patient care.
A midline catheter is typically inserted in the upper arm or upper chest, with the tip terminating in the axillary, brachial, or basilic veins.
Midline catheters are longer than peripheral catheters but shorter than central venous catheters. They range from 8 to 20 centimeters in length.
The tip of a midline catheter lies in the peripheral vasculature, usually below the axillary vein.
A midline catheter kit is primarily utilized for patients requiring intermediate-term intravenous access, usually for a duration of 1 to 4 weeks. They are suitable for infusing medications, antibiotics, and certain non-vesicant solutions.
Midline catheters generally pose fewer complications than central venous catheters. They have a lower risk of bloodstream infections and deep vein thrombosis, but care should still be taken to maintain proper aseptic techniques during midline catheter insertion and care.
Midline catheters are designed for intermediate-term use, ranging from a few days to several weeks. They are not suitable for prolonged therapy.

A central venous catheter is usually inserted in larger veins such as the internal jugular, subclavian, or femoral veins, with the tip positioned in the superior vena cava or right atrium.
Central venous catheters are longer and can extend beyond 20 centimeters, allowing for placement in larger central veins.
A central venous catheter tip position is in the central circulation, enabling the administration of medications and fluids directly into the superior vena cava or right atrium.
A central venous catheter kit is indicated for patients needing long-term intravenous therapy, including chemotherapy, total parenteral nutrition (TPN), frequent blood sampling, or hemodialysis.
Central venous catheters have a higher risk of complications, including infections, pneumothorax, arterial puncture, thrombosis, and catheter-related bloodstream infections. Central venous catheter placement requires skilled healthcare providers and vigilant monitoring.
Central venous catheters are intended for long-term access and can remain in place for weeks to months, depending on the patient's needs.
In summary, midline catheters and central venous catheters have distinct characteristics and applications. Understanding the differences between a midline catheter and a central venous catheter is crucial for healthcare professionals when deciding which type of catheter to use for a specific patient.
Midline catheters are shorter, inserted in peripheral veins, and utilized for intermediate-term therapy. Central venous catheters are longer, placed in larger central veins, and employed. Healthcare professionals must carefully consider the specific needs of each patient when selecting the appropriate catheter type to ensure safe and effective intravenous therapy.
