Ultrasound guided sciatic nerve block

Abstract

Regional anesthesia is important in modern anesthesia practice and comprises a diverse group of anesthesia procedures including plexus and peripheral nerve blockade. Sciatic nerve blockade is a common regional anesthesia procedure used for lower limb surgery. The origin of the sciatic nerve is the sacral plexus, specifically from the lumbosacral trunk (ventral rami of L4-5) and the ventral rami of sacral nerves S1-S3. The sciatic nerve is the largest and longest nerve in the human body. The roots of the sciatic nerve can be identified in the pelvis (sacral plexus), and the nerve or its branches can be located in the gluteal region, posterior thigh, popliteal fossa and ankle. Therefore, sciat..
