The current practice for pain management utilizes systemic opioid analgesics. The use of opioids is an excellent analgesic choice, but they carry a significant burden for potential adverse effects. It is vital that providers have a variety of approaches to acute pain control. The use of femoral nerve blocks (FNBs) and fascia iliaca compartment blocks (FICB) are an alternative method of pain control in the ED. They have advantages over systemic opiates in that they do not require hemodynamic monitoring, have less adverse effects, and more importantly they in- duce rapid pain control with longer duration than systemic analgesics (Cross & Warkentine, 2016). This manuscript examines a review of literature and identifies the efficacy, patient safety, indica- tions, contraindications, patient satisfaction, and ultrasound-guided FNB and FICB techniques.
