A comparison of the supraclavicular and infraclavicular views for imaging the subclavian vein with ultrasound.

Introduction: Ultrasound guidance for central line placement in the subclavian vein (SCV) is more efficient and safer than landmark-based technique. The supraclavicular (SC) approach is an alternative to the infraclavicular (IC) approach, but the research is sparse. The objective was to determine which approach provides the best view.
