Purpose: Total hip arthroplasty (THA) is often associated with moderate to severe pain. The present study compared the efficacy of circum-psoas block (CPB) with supra-inguinal fascia iliaca block (SIFIB) for postoperative analgesia in patients undergoing THA.Patients and Methods: In this randomized trial, sixty-four patients undergoing THA were allocated randomly to the CPB group or SIFIB group with 40 mL of 0.3% ropivacaine. The primary outcome was dynamic pain score at 6 h postoperatively. Secondary outcomes included dynamic pain scores at 12, 24 and 48 h; static pain scores; sensory and motor block; opioid consumption; time to first opioid request; length of hospital stay; patient satisfaction; and adverse events.Results: CPB patients showed significantly lower dynamic pain scores at 6 (3.11 ± 0.66 vs 4.47 ± 0.74, respectively; P = 0.000), 12 (2.52 ± 0.73 vs 3.53 ± 0.85, respectively; P = 0.000) and 24 h (2.30 ± 0.57 vs 2.87 ± 0.71, respectively; P = 0.001) after surgery, as well as lower static pain scores at 6 and 12h (P = 0.001 and P = 0.033 respectively) than SIFIB patients. Lower opioid consumption was observed in the CPB group at 24 and 48 h (P = 0.000, both) than in the SIFIB group. Patients in the CPB group reported improved quadriceps strength at 6 and 12 h (P = 0.000, both), as well as better muscle strength of hip flexion at 6, 12 and 24 h (P = 0.000, P = 0.000 and P = 0.025 respectively). Compared with SIFIB, CPB was associated with increased sensory block coverage at 6, 12 and 24 h (P = 0.000, P = 0.000, and P =0.022, respectively).Conclusion: CPB has a greater potential to alleviate postoperative pain and improve recovery in THA patients than SIFIB.
