Randomized Controlled TrialUltrasound Guided Femoral Nerve Block to Provide Analgesia for Positioning Patients with Femur Fracture Before Subarachnoid Block: Comparison with Intravenous Fentanyl.
Background Positioning patients with fractured femur for subarachnoid block is painful. Intravenous analgesics or peripheral nerve block like femoral nerve block or fascia iliaca compartment block are some of the available techniques to reduce pain. We compared the efficacy of femoral nerve block and intravenous fentanyl in providing effective analgesia before positioning for subarachnoid block. ⋯ Level of significance was set at 0.05. Result FNB group had significantly less VAS scores (median) than IVF group :2 vs 3; p=0.037) during positioning for spinal anaesthesia. Procedure time (median) for spinal anaesthesia was also significantly less in FNB than in IVA group (10 vs 12 min; p=0.033) Conclusion Ultrasound guided femoral nerve block was more effective than intravenous fentanyl for reducing pain in patients with proximal femur fracture before spinal anaesthesia.
