USG versus PNS guided combined femoral and sciatic nerve block for lower limb surgery

Abstract

Introduction- Combined femoral nerve block (FNB) and sciatic nerve block (SNB) is a 
popular method for reducing postoperative pain following orthopaedic surgery on the lower 
limbs because it effectively reduces pain. Avoiding the negative effects of central neuraxial 
blockage, FNB delivered via the landmark approach, peripheral nerve stimulation (PNS), or 
ultrasound (USG) produces efficient analgesia. The application of nerve blocks in clinical 
practice has been transformed by USG-guided blocks. In this study, the effectiveness of 
peripheral nerve stimulator (PNS)-guided and ultrasonography (USG) guided combined 
femoral nerve block and sciatic nerve block in knee arthroscopic operations is compared.
