Comparison of Analgesic Efficacy of Suprainguinal Fascia Iliaca and Quadro-iliac Blocks in Hip Fracture Surgery
Sponsor: Hitit University
Summary
This prospective, randomized, double-masked trial compared two ultrasound-guided regional analgesic techniques, suprainguinal fascia iliaca block (SIFI) and quadro-iliac plane block (QIPB), in adults undergoing surgery for hip fracture under spinal anesthesia. The primary outcome was pain at rest and during movement, assessed using a 0-10 numeric rating scale during the first 24 hours after complete resolution of spinal motor block (Bromage score 0). Secondary outcomes included postoperative opioid consumption, rescue analgesic requirements, nausea and vomiting, quality of recovery, time to first assisted standing and other recovery measures, and patient satisfaction. Both groups received the same postoperative multimodal analgesic regimen. Eighty-five participants were randomized, and 70 participants completed follow-up and were included in the reported analysis.

Interventions
Suprainguinal Fascia Iliaca Block
the area between the iliacus muscle and the fascia iliaca will be reached at the level of the anterior superior iliac spine, proximal to the inguinal ligament. Hydrodissection will be performed with 2 mL of saline, followed by the injection of 40 mL of 0.25% bupivacaine.
Quadro-Iliac Plane Block
Ultrasound-guided injection of 40 mL 0.25% bupivacaine (100 mg) into the fascial plane related to the posterior surface of quadratus lumborum at its attachment to the iliac crest, before spinal anesthesia. A linear probe and an 80-mm peripheral block needle were used. Patients were prone or, when pain prevented tolerance of prone positioning, in lateral decubitus.
