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.

METHODS: This was a prospective randomized study. Patients aged over 18 years old who requiring elective central venous catheterization were included. Non-inclusion criteria were thrombosis of the vein or major coagulopathy. All catheterizations were performed by two anaesthesiology residents. Patients were randomized into two groups: ultrasound guidance group (US group) and anatomical landmarks (LM group). The main outcome was the success rate. The secondary outcomes were the first attempt success rate and the incidence of complications.

RESULTS: Seventy patients were included (35 in each group). The success rate was higher in US group compared to LM group without statistical significance (100% vs 85.7%; p=0.054). The first attempt success rate was significantly higher in the US group (82.9% vs. 40%; p <10-3). The incidence of mechanical complications was significantly lower in the US group compared to LM group (5.7% vs. 37.1%; p=0,001).

CONCLUSION: according to our study, US guidance for SCV catheterization seems to be an interesting alternative to anatomical landmarks approaches.
