Influence of the Shoulder Position on the Catheter Tip Location During Infraclavicular Subclavian Approach

Infraclavicular approach of the subclavian veins is commonly used for central venous access. Aberrant locations of catheter tip are frequently quoted for this approach, but few studies have been performed to document the relationship between the shoulder position and catheter tip location. This prospective study was performed to assess the influence of the shoulder position on the safe and proper placement of infraclavicular subclavian catheters.

Inclusion Criteria:

• adult patients requiring central venous catheterization due to major procedures such as neurosurgery or thoracic surgery.

Exclusion Criteria:

• chest deformities,
• coagulopathy,
• diaphragmatic dysfunction,
• pulmonary malformation,
• history of prior clavicle fracture, or
• infection over the puncture site.
