Efficacy of ultra sound guided popliteal sciatic nerve block and distal sciatic bifurcation nerve block in providing anaesthesia for below knee surgeries.

This study aims to compare the efficacy of two ultrasound-guided techniques for sciatic nerve block in below-knee surgeries: the popliteal sciatic nerve block and the distal sciatic bifurcation nerve block. Conducted as a randomized controlled trial, the research involves adult patients scheduled for elective below-knee procedures. Participants are randomly assigned to receive either the popliteal block or the bifurcation block, with the primary outcome being the time required to achieve complete sensory and motor blockade. Secondary outcomes include the duration of analgesia, pain scores, motor function, complications, and patient satisfaction. The study seeks to determine which technique offers a faster onset and more effective anesthesia, thereby potentially improving surgical efficiency and patient comfort.
