Site-specific complications of central venous catheterization under systematic ultrasound guidance: a target trial emulation revisiting the 3SITES study

Key Points

• Subclavian access in central venous catheterization results in a lower thrombotic risk, enhancing patient safety.
• Reduced infectious risk and no increase in mechanical complications support subclavian access for intensive care units.
• The analysis revisited the findings from the 3SITES study, emphasizing the benefits of ultrasound guidance.
• These findings may influence catheterization practices, highlighting the importance of site selection for improving outcomes.
