DIPB vs. SIFIB for Postoperative Analgesia After Hip Surgery
Comparison of the Effects of Deep Iliacus Plane Block (DIPB) and Suprainguinal Fascia Iliaca Block (SIFIB) on Postoperative Analgesia in Patients Undergoing Hip Surgery: A Randomized Controlled Study

INTERVENTIONAL
Conditions
Summary
This randomized, double-blind clinical trial aims to compare the effectiveness of the Deep Iliacus Plane Block (DIPB) and the Suprainguinal Fascia Iliaca Block (SIFIB) for postoperative pain control in patients undergoing primary total hip arthroplasty. Effective analgesia after hip surgery is essential for early mobilization, reduction of complications, and improved recovery outcomes. Seventy patients scheduled for elective hip arthroplasty under spinal anesthesia will be randomly assigned to receive either DIPB or SIFIB at the end of surgery. Postoperative pain scores, opioid consumption, motor block, and block-related complications will be evaluated over a 48-hour period. The study aims to determine whether DIPB provides superior or comparable analgesia with reduced motor blockade compared to SIFIB, thereby contributing to safer and more comprehensive postoperative pain management in hip surgery patients.
