An Iliopsoas Plane Block After Total Hip Arthroplasty

Not Applicable

Completed

• Conditions: Total Hip Arthroplasty
• Interventions: Procedure: iliopsoas plane block group; Procedure: sham block group

• Registration Number: NCT05212038
• Lead Sponsor: Gangnam Severance Hospital

Brief Summary

Nielsen et al. reported that when iliopsoas plane block was performed on healthy volunteers, the injection solution in Hip MRI was confined to the myofascial compartment, which was known to include all sensory branches of the femoral nerve that control the hip joint. The maximal muscle strength of knee extension did not decrease before and after Iliopsoas plane block in Volunteer. Since there is no clinical study conducted on patients after the volunteer study, the investigators intend to evaluate the analgesic and motor preserving effects of the iliopsoas plane block in a group of patients undergoing total hip arthroplasty.

Primary Outcome Measures

Name	Time	Method
Numeric rating scale pain score at rest	up to 48 hours after the surgery	Pain intensity at rest will be evaluated by an 11-point numeric rating scale (NRS: 0 = no pain, 10 = worst imaginable pain) 1, 6, 24, and 48 hours after the surgery.

Secondary Outcome Measures

Name	Time	Method
Numeric rating scale pain score at movement	up to 48 hours postoperatively	Pain intensity during 45-degree passive flexion of the hip with the ipsilateral knee flexed naturally will be evaluated by an 11-point numeric rating scale (NRS: 0 = no pain, 10 = worst imaginable pain) 1, 6, 24, and 48 hours after the surgery.
Postoperative opioid consumption	postoperative 24, 48hours	morphine equivalent dose
