Effect of beam steering on the visibility of echogenic and non-echogenic needles: a laboratory study.

Abstract

PURPOSE During peripheral nerve block procedures, needle visibility decreases as the angle of needle insertion relative to skin increases due to loss of reflective signals. The primary aim of our study was to compare the effect of beam steering on the visibility of echogenic and non-echogenic block needles. METHODS PAJUNK non-echogenic and echogenic… (More)
