Investigation of a new echogenic needle for use with ultrasound peripheral nerve blocks.
A new 'texturing method' has been developed for nerve block needles in an attempt to improve the ultrasonic image of the needles. Using a synthetic phantom, these textured needles were compared to currently available needles. The textured needle had improved visibility under ultrasound. This type of needle may assist the anaesthetist perform ultrasound-guided regional anaesthesia.
