Summary

Needle tip visualization, although fundamental to the safety and efficacy of ultrasound-guided regional anesthesia (UGRA), can be extremely challenging. This problem is most marked at steep insertion angles. Studies in patients with UGRA demonstrate that echogenic needle designs have the potential to offer improved visibility and accuracy.

Our study pursues another approach. We use (for differentiation) echogenic nerve block needles with ANV®, a new SonoSite software-upgrade (Advanced Needle Visualization Technology®). We will compare UGRA with ANV® against standard UGRA without using this SonoSite software-upgrade. Patients undergoing femoral, supraclavicular or other nerve blocks as part of their routine anesthetic management are included.

This work represents the first randomized controlled double blinded clinical trial of ANV® in patients undergoing UGRA. We hypothesize, that we can decrease the time without needle visualization (Loss of needle time in percentage of procedure time) during in-line regional anaesthesia. Furthermore we will record quality of visibility, duration of procedure and insertion angle of the needle.
