Comparison of the Postoperative Analgesic Efficacy of Quadro-Iliac Plane Block, Suprainguinal Fascia Iliaca Block, and Standard Analgesia Protocol in Patients Undergoing Hip Fracture Surgery Under Spinal Anesthesia: A Prospective, Randomized, Double-Blind, Controlled Trial
Comparison of the Postoperative Analgesic Efficacy of Quadro-Iliac Plane Block, Suprainguinal Fascia Iliaca Block, and Standard Analgesia Protocol in Patients Undergoing Hip Fracture Surgery Under Spinal Anesthesia: A Prospective, Randomized, Double-Blind, Controlled Trial
Hip fracture surgery is associated with significant postoperative pain and increased opioid requirements. Regional anesthesia techniques may improve analgesia and reduce opioid consumption. This prospective, randomized, double-blind, controlled trial aims to compare the postoperative analgesic efficacy of Quadro-Iliac Plane Block (QIPB), Suprainguinal Fascia Iliaca Block (SIFIB), and standard analgesia in patients undergoing hip fracture surgery under spinal anesthesia. The primary outcome is cumulative tramadol consumption during the first 24 postoperative hours. Secondary outcome measures include postoperative pain intensity, rescue analgesic requirement, incidence of postoperative nausea and vomiting, Quality of Recovery-15 (QoR-15) score, and patient satisfaction score.
Hip fracture surgery is frequently associated with severe postoperative pain, delayed mobilization, and increased opioid consumption. Regional anesthesia techniques have been increasingly used to improve postoperative analgesia and reduce opioid-related adverse effects.
This prospective, randomized, double-blind, controlled, multicenter study aims to compare the postoperative analgesic efficacy of Quadro-Iliac Plane Block (QIPB), Suprainguinal Fascia Iliaca Block (SIFIB), and standard analgesia in patients undergoing hip fracture surgery under spinal anesthesia. Patients will be randomly allocated in a 1:1:1 ratio to one of the three study groups.
All surgical procedures will be performed under spinal anesthesia. Patients assigned to the QIPB group will receive ultrasound-guided quadro-iliac plane block, whereas patients assigned to the SIFIB group will receive ultrasound-guided suprainguinal fascia iliaca block. Patients in the control group will receive standard multimodal analgesia without a regional block.
The primary outcome measure is cumulative tramadol consumption during the first 24 postoperative hours. Secondary outcomes include postoperative pain scores, rescue analgesic requirements, time to first rescue analgesia, postoperative nausea and vomiting, quality of recovery assessed with the Quality of Recovery-15 (QoR-15) questionnaire, patient satisfaction, intraoperative opioid consumption, and block-related complications.
The study is planned to enroll 90 patients across three centers.
