Brief 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.

Outcome Measures

Primary Outcomes (1)

• Postoperative pain intensity

  Postoperative pain assessed using the Numeric Rating Scale (NRS; 0 = no pain, 10 = worst pain imaginable) at rest and during movement following total hip arthroplasty.

  2, 4, 8, 16, 24, and 48 hours postoperatively

Secondary Outcomes (3)

• Opioid consumption

  From the end of surgery to 48 hours postoperatively

• Motor block

  4, 8, 16, 24, and 48 hours postoperatively

• Pain during movement

  2, 4, 8, 16, 24, and 48 hours postoperatively

Study Arms (2)

Suprainguinal Fascia Iliaca Block (SIFIB)

EXPERIMENTAL

Participants randomized to this arm will receive an ultrasound-guided suprainguinal fascia iliaca compartment block at the end of surgery using 0.25% bupivacaine (30-40 mL, weight-adjusted) for postoperative analgesia following primary total hip arthroplasty.

Procedure: Suprainguinal Fascia Iliaca Block

Deep Iliacus Plane Block (DIPB)

EXPERIMENTAL

Participants randomized to this arm will receive an ultrasound-guided deep iliacus plane block at the end of surgery using 0.25% bupivacaine (30-40 mL, weight-adjusted) for postoperative analgesia following primary total hip arthroplasty.

Procedure: Deep Iliacus Plane Block
