Ultrasound Guidance Improves the Success of Sciatic Nerve Block at the Popliteal Fossa

Abstract

Ultrasound guidance enhances the quality of popliteal sciatic nerve block compared with single injection, nerve stimulator-guided block using either a tibial or peroneal endpoint. Ultrasound guidance resulted in higher success, faster onset, and progression of sensorimotor block, without an increase in block procedure time, or complications.
