What this Trial Is About
Researchers are evaluating two different ultrasound-guided nerve block techniques to manage pain in patients undergoing total hip arthroplasty (THA), a common surgery for hip fractures and osteoarthritis. The study compares the anterior iliopsoas muscle space block and the supra-iliac anterior quadratus lumborum block as pre-emptive analgesia during general anesthesia. Effective pain control is crucial to improve recovery, reduce hospital stay, and support early mobilization after surgery. Participants will be randomly assigned to one of three groups: a control group receiving general anesthesia alone, a group receiving the anterior iliopsoas muscle space block with 30 ml of bupivacaine 0.25% before general anesthesia, or a group receiving the supra-iliac anterior quadratus lumborum block with the same anesthetic dosage before general anesthesia. These blocks target nerves around the hip joint to reduce postoperative pain. During the study, researchers will assess pain using the Visual Analogue Scale at multiple times up to 24 hours after surgery and measure the total rescue analgesia used in the first 24 hours. Patients will be monitored closely for outcomes related to pain relief and recovery. The study is sponsored by Zagazig University and aims to identify the most effective regional anesthesia technique for THA patients aged 50 to 80 years.
