Analgesic Efficacy of Continuous S-ESP vs Continuous FICB After Hip Arthroplasty

The primary objective of this prospective, randomized, double-blind controlled trial is to compare the postoperative analgesic efficacy of continuous Sacral Erector Spinae Plane (S-ESP) block versus continuous Fascia Iliaca Compartment Block (FICB) in adult patients undergoing elective hip replacement surgery. The investigators hypothesize that the continuous S-ESP block will provide non-inferior or superior pain relief compared to continuous FICB, while potentially reducing the incidence of motor block and facilitating earlier postoperative mobilization. Participants will be randomly assigned to receive either an S-ESP or FICB catheter for continuous local anesthetic infusion over 48 hours postoperatively. Postoperative pain scores, opioid consumption, and functional recovery will be systematically evaluated.
