What is the Fischer 123 technique?

5. Fischer 1-2-3 technique. The Fischer 1-2-3 technique, which is also called the indirect technique, requires the identification of several anatomical landmarks, including the internal and external oblique ridge, and coronoid notch. In this technique, the anesthetic is injected using three different needle positions.

How does intravenous regional anesthesia work?

A Bier block essentially consists of injecting local anesthetic solutions into the venous system of an upper or lower extremity that has been exsanguinated by compression or gravity and that has been isolated by means of a tourniquet from the central circulation.
