Ultrasound guidance versus anatomical landmarks for subclavian vein catheterization: a prospective study.

Background: Several clinical practice guidelines strongly support the use of ultrasound guidance (USG) for internal jugular vein catheterization. The level of evidence concerning the use of USG for subclavian vein (SCV) cannulation remains low.

Aim: To compare the effectiveness and safety of USG and anatomical landmarks approaches for cannulation of SCV.
