These types of cannulas are usually inserted into the deep venous system, most commonly in the upper limbs, usually under ultrasound navigation.

Depending on the placement of the end of the catheter, either in one of the peripheral veins or in the cavo-atrial junction (where the superior vena cava meets the right atrium), we differentiate between Midline Catheter and PICC (Peripherally Inserted Central Catheter). Preferred veins for cannulation in the upper limbs are the basilic vein, the cephalic vein or the brachial vein. General indications are the long-term use of antibiotics, parenteral nutrition, fluids, electrolytes and chemotherapy.

•   relatively low frequency of bacterial infections (dependent on proper nursing care)
•   complications related to the insertion of CVC are avoided
•   suitable for outpatients
•   safe in high-risk patients (coagulopathy, anticoagulation therapy, tracheostomy)

•   practically demanding, requires ultrasound experience
