Sciatic Nerve Block in Single Nerve Block Technique for Unilateral Foot Surgery - an Alternative to Spinal Anaesthesia

Background: In lower extremity surgeries, central neuraxial block or peripheral regional anesthesia technique can be used, mainly in elderly patients. This study investigates the efficiency of spinal anesthesia and sciatic nerve block techniques in lower extremity surgery. Spinal anesthesia may impair hemodynamic stability; peripheral nerve blocks targeting the sciatic nerve may be a useful alternative
