We hypothesize that a TQL block, when compared to fascia iliaca block (FIB), will provide better analgesia and less motor block in the initial 24-h postoperative period.Patients and Methods: Fifty patients undergoing elective hip replacement surgery, ASA I–III, were included in the study. Patients were randomized into two groups. Patients in group A received spinal anesthesia followed by FIB. Patients in group B received spinal anesthesia followed by TQLB. Postoperative pain scores and motor block were assessed at 6 and 24 hours. The primary outcome measure was 24 h total morphine consumption. Secondary outcome measures included pain score (VNS) and motor block (modified Bromage scale) at 6 and 24 h postoperatively.Results: There was no statistical difference in morphine consumption between the two groups (p-value 0.699). There was no difference in pain scores at 6 h (p-value 0.540) or 24 h (p-value 0.383). There was no difference in motor block at 6 h (p-value 0.497) or at 24 h (p-value 0.773).Conclusion: Transmuscular quadratus lumborum block along with spinal anesthesia for patients undergoing elective hip replacement surgery does not reduce opioid consumption or motor weakness when compared to fascia iliaca block. The results and conclusion apply to a dose of 20 mL of 0.25% bupivacaine used in each group.Keywords: pain scores, motor block, opioid consumption |
