These peripheral catheters are inserted in the upper arm with the tip located just below the axilla.
Usually up to maximum of 20cm in size, they are designed for short-term peripheral drug delivery.
They are easy to place, but are contraindicated for patients with a history of venous thrombosis and limited blood flow to body extremities.
Midline catheters are used less commonly because of the increasing use of peripherally-inserted central catheters (PICCs).
