Aiguilles échogènes : intérêt et performance ?

Ultrasound-guided regional blocks required a good ultrasound imaging of needles. The quality of ultrasound imaging is impaired when the needle is not perpendicular to the ultrasound beam. New needles engineered to be more easily visible within the ultrasound beam by increasing the ultrasound-reflecting surface, are now available. These needles provide better ultrasound image especially during deep blocks performance.
