Ultrasound-guided suprainguinal fascia iliaca block to position the patient for neuraxial anaesthesia in acetabular surgery - a randomized controlled pilot study.

Introduction: Neuraxial anaesthesia is a common choice for most hip and lower limb operations. Pain associated with positioning is often a deterrent, and the vast literature suggests different regional blocks and opioids for these patients. Patients with acetabular fractures may experience increased pain, and thus are more difficult to position for the neuraxial block.
