Advantages
Disadvantages
Subclavian
- It is a large vein with surrounding tissue preventing collapse 1
- There are fixed bony landmarks 1
- It is a comfortable catheter position for the patient 1
- It allows for an easier secure fixation of the catheter 1
- It is a clean site with reduced risk of infection, potentially allowing longer duration of use 1
- Higher incidence of complications particularly pneumothorax 1
- Difficult to compress in the event of arterial puncture 1
- Landmarks are less readily identifiable, particularly in obese patients 1
- More difficult to visualise with ultrasound due to clavicle 1 - more lateral approach required
- Curved route makes misplacement of catheter more likely 1
- Can lead to subclavian stenosis precluding the use of the extremity for renal access 1
