Researchers are evaluating the effects of a lumbar erector spinae plane (ESP) block on managing pain after total hip arthroplasty, a surgery to replace the hip joint. The ESP block, first described in 2016, is a relatively simple technique initially used for chronic thoracic pain. This study compares the pain control achieved by the ESP block with standard multimodal analgesia after hip surgery in adults aged 18 to 85 years. Participants are randomly assigned to one of two groups: the ESP block group or the placebo group. In the ESP block group, after anesthesia induction, an ultrasound-guided lumbar ESP block is performed by injecting 30 ml of local anesthetic near the erector spinae muscle at the L4 spinal level. The placebo group receives standard multimodal analgesia without the ESP block. All patients receive postoperative pain management including intravenous paracetamol, oral paracetamol for 4 weeks, diclofenac tablets for 5 days, and patient-controlled analgesia (PCA) using morphine as needed. Participants are monitored in a continuous care unit for 24 hours post-surgery. Researchers measure morphine consumption during the first 24 hours as the primary outcome. Secondary outcomes include intraoperative opioid use, postoperative pain scores, ability to sit, and side effects related to opioid use. The study aims to assess differences in opioid consumption and pain control between the two groups during the recovery period.
