[Ultrasound-guided infraclavicular axillary vein cannulation].

BACKGROUND AND OBJECTIVE: Percutaneous central venous cannulation is a challenging procedure. Traditionally, an external landmark technique has been used to identify puncture site. We wanted to evaluate an ultrasound-guided technique for the axillary vein cannulation, looking specifically at the ease of use, success rate and decreased complications.

METHODS: Sixty consecutive surgical patients scheduled for central venous catheter placement were registered. An ultrasound scanner made for guiding an in plane puncture of axillary vein was used. After locating the vessels, an echo-guided sterile procedure was performed to cannulate the vein.

RESULTS: Cannulation was successful in all patients, and there were no complications during insertion of the catheters. Both axillary veins were cannulated, and the vein was punctured successfully at first attempt in 95% of the patients. The median time from the start of the first puncture (of the skin) until the aspiration of blood was 15 (7- 135) seconds.

CONCLUSION: This ultrasound-guided technique for inserting central venous catheters in axillary vein was easy to apply. This procedure could increase precision and safety in patients undergoing axillary vein cannulation.
