Post-Hoc Cost-Utility Analysis of Ultrasound-Guided Erector Spinae Plane (ESP) Block Versus Total Intravenous Anesthesia (TIVA) in Posterior Scoliosis Correction Surgery: Evidence From the Egyptian EQ-5D-5L Value Set

Posterior scoliosis correction surgery is associated with sever postoperative pain that necessitate high perioperative opioid doses to alleviate pain . Regional anesthesia techniques such as ultrasound-guided erector spinae plane (ESP) block have emerged as promising strategies for improving postoperative analgesia and reducing opioid consumption. This secondary analysis evaluates the cost-utility of ESP block compared with total intravenous anesthesia (TIVA) alone in patients scheduled for posterior scoliosis correction surgery. The analysis assesses postoperative quality of life using the EQ-5D-5L instrument value sets from Egyptian population alongside healthcare costs within the early postoperative period. The study aims to determine whether ESP block provides improved patient outcomes and represents a cost-effective strategy for perioperative pain management in scoliosis surgery
