Intravenous analgesia with opioids versus femoral nerve block with 0.2% ropivacaine as preemptive analgesic for fracture femur: A randomized comparative study

Femoral fractures are extremely painful and pain invariably worsens on any movement. Anesthesia for fracture femur surgery is usually provided by spinal block. This study was undertaken to compare the analgesic effects of femoral nerve block (FNB) using nerve stimulator with 0.2% ropivacaine (15 ml) and intravenous (I.V.) fentanyl before patient positioning for fracture femur surgery under spinal anesthesia
