Ultrasound-guided transgluteal sciatic nerve analgesia for refractory back pain in the ED

Abstract

Sciatic radicular back pain is a painful condition resulting in approximately 2% of emergency department (ED) visits a year. Typically, the ED treatment has been limited to various analgesic regimens with limited success sometimes resulting in hospital admissions for pain control. Regional anesthesia has become increasing popular for lower-limb analgesia, but has not universally permeated the ED setting. The transgluteal sciatic nerve block (TGSNB) is a procedure that can provide effective analgesia for lower extremity pain. Herein, we present the first technical description and clinical response to ultrasound-guided TGSNB performed by emergency physicians for acute pain control of sciatic back pain through a series of cases.
