Emergency Physician-performed Ultrasound-guided Femoral Nerve Blocks in Patients With Hip Fractures.

Study Overview
=================
Brief Summary
-----------------
In this prospective study, emergency physicians perform ultrasound-guided femoral nerve block for patients with hip fractures. We compare the effectiveness of analgesia and patient satisfaction of ultrasound-guided femoral nerve block with liberal use of the pain medication in the emergency department. The primary outcome is the assessment of time to relief the pain with fewer adverse effects and less rescue pain medication use. The secondary outcome is patient satisfaction with pain management.
