Effect of early ultrasound-guided femoral nerve block on preoperative opioid consumption in emergency patients with hip fracture: a randomized trial.

Background And Importance: Ultrasound-guided femoral nerve block (FNB) could be used as part of a multimodal preoperative pain management for patients with hip fracture. Evidence of the effects of its early implementation in the emergency room as an immediate alternative to intravenous morphine titration is sparse.

Objective: To investigate the effect of an early ultrasound-guided FNB performed by emergency physicians on preoperative opioid consumption, compared to standard pain management.
