Central Venous Access Guidelines

Site Selection and Anatomical Considerations

The American College of Radiology recommends that the right internal jugular vein is superior to the left IJV for central venous access due to its straighter path to the superior vena cava, resulting in easier catheter positioning and fewer mechanical complications 1, 2
The right internal jugular vein requires shorter catheter length (15 cm) compared to left-sided approaches 1
Left IJV placement is associated with poor blood flow rates, higher rates of stenosis and thrombosis, and may jeopardize venous return from the left arm 2, 1

The American Society of Anesthesiologists recommends using real-time ultrasound guidance for all IJV catheterizations unless emergency circumstances prevent it 3, 4

The subclavian vein has the lowest infection risk, followed by internal jugular, with femoral having the highest risk 5
Internal jugular route carries intermediate infection risk compared to other central venous access sites 5

For short-term access (days to weeks), non-tunneled polyurethane catheters (20-30 cm) are appropriate for hospitalized patients requiring continuous use 6, 7
For medium-term access (up to 3 months), PICCs, Hohn catheters, or tunneled catheters are suitable 6, 8
For long-term access (>3 months), tunneled catheters (Hickman, Broviac, Groshong) or totally implantable ports are required 6, 7

For hemodialysis patients, the right IJV is strongly preferred for tunneled dialysis catheters 2, 1
Avoid subclavian vein unless no other option exists, as it causes central venous stenosis and precludes future arteriovenous fistula creation in the ipsilateral arm 2, 4, 1

Patient positioning should be performed with the patient in Trendelenburg position when clinically appropriate and feasible 3
Select the smallest catheter diameter appropriate for the clinical situation 3
Ideally, catheter diameter should be one-third or less of the vein diameter as checked by ultrasound 6, 8

Aseptic technique for catheter maintenance should include cleaning catheter access ports with appropriate antiseptic before each access 3
Implement proper dressing changes and regular assessment protocols 5

The American College of Radiology recommends the subclavian vein as the preferred alternative for most indications when the internal jugular vein is not accessible, followed by the contralateral internal jugular vein, with femoral access reserved for emergency situations or when upper body veins are contraindicated 9, 10
The American College of Radiology suggests using the contralateral internal jugular vein if one side is unavailable 11, 9
The Centers for Disease Control and Prevention recommends subclavian over jugular or femoral sites for nontunneled catheters in adults to reduce catheter-related bloodstream infections 10
The American Journal of Kidney Diseases advises avoiding subclavian veins in hemodialysis patients unless no other option exists, as stenosis permanently compromises the ipsilateral arm for future arteriovenous fistula creation 10, 12

The American College of Radiology recommends the basilic vein as the preferred peripheral access vein due to its size and lower thrombosis risk 9, 10
The American College of Radiology notes that the cephalic vein has a higher thrombosis risk due to its smaller size and susceptibility to kinking 9, 10
The American College of Radiology warns that the brachial vein carries a greater risk of arterial and nerve injury 9, 10

The American College of Radiology advises that the femoral vein should be avoided unless there is a contraindication to other sites, due to its high infection risk and association with deep vein thrombosis 9, 10, 11

The American College of Radiology and the American Journal of Kidney Diseases recommend never using subclavian veins in hemodialysis patients due to the risk of permanent stenosis 10, 12
The American Journal of Kidney Diseases suggests considering femoral access for temporary dialysis catheters rather than risking subclavian stenosis 12
