Comparing Ultrasound-Guided Transgluteal Nerve Block to Standard Care

Purpose

The goal of this clinical trial is to compare transgluteal sciatic nerve block to standard of care to treat sciatic back pain in adult patients who present to the emergency department. The main question it aims to answer is: Is a transgluteal sciatic nerve block better than standard of care in improving pain in ER patients with sciatic back pain? If there is a comparison group: Researchers will compare patients who receive transgluteal sciatic nerve blocks to patients who receive standard of care to see if pain scores improve in ER patients with sciatic back pain. Participants will be randomized into the transgluteal sciatic nerve block group or the control group (standard of care). Participants will be asked to answer questions about their pain and will be asked to walk a timed short distance.

Transgluteal sciatic nerve block
Patients will receive an ultrasound-guided transgluteal sciatic nerve block with 10-20 mL of 0.2% ropivacaine injected around the affected sciatic nerve at the level of the greater trochanter.
