An Iliopsoas Plane Block After Total Hip Arthroplasty

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.

Treatment and study plan

iliopsoas plane block group

Procedure

Ultrasound-guided iliopsoas plane block with 0.75% ropivacaine 10 ml and epinephrine 0.05 ml (1:200,000) 10 ml

sham block group

Procedure

Ultrasound-guided iliopsoas plane block with normal saline 10 ml

Primary outcomes

  1. Numeric rating scale pain score at rest

    Time frame: 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 outcomes

  1. Numeric rating scale pain score at movement

    Time frame: 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.

  2. Postoperative opioid consumption

    Time frame: postoperative 24, 48hours

    morphine equivalent dose
