Background: Femoral nerve block (FNB) is an option for pain management in patients with femur fractures. Aim: Compare the analgesic effects of femoral nerve block (FNB) with intravenous (IV) fentanyl prior to positioning patients with fractured femur for spinal block. Materials and Methods: It is randomized prospective study was undertaken at for a period of 9 months. Total 50 Subjects participated in study, divided into 2 groups, Group-L(lignocaine) 25 patients received 20 ml of 1% lignocaine around femoral nerve under ultrasound guidance and in plane approach. Group- F(Fentanyl)-25 patients received 1 mic/kg of fentanyl intravenously. Results: All the demographic details are not significant in both the groups. Mean arterial pressure is significantly decreased (p-value<0.05) during positing in group F and there is significantly decreased O2 saturation in patients also.Pain score during positioning is decreased significantly in group- L. Out of 25 patients in Group L, 22 were found satisfactory with this method. Conclusion: Femoral nerve block provides better analgesia, patient satisfaction, less time for anaesthesia and satisfactory positioning.
