USG or clinical judgment or both?

Abstract

Regional anesthesia, including central neuraxial block, peripheral nerve block and interventional pain
injection is traditionally done with the help of the landmarks and clinical judgment. Today, injections are
done with the help of ultrasound (USG). In this paper, two methods are compared and the value of both
methods is evaluated. The superiority of USG is obvious, but these two techniques are truly along the
same way and complement each other.
