Clinical Trial Summary

The goal of this study is to evaluate the analgesic efficacy of bilateral erector spinae plane (ESP) blocks after lumbar and lumbo-sacral spine surgery by assessing postoperative pain scores and opiate requirements as the primary outcome measures. We are aiming to investigate how ESP blocks, performed under ultrasound guidance at the T12 vertebral level, contribute to postoperative pain control. This will be determined by measuring numerical rating pain scores repeatedly following surgery and opiate consumption until patient discharge from hospital. These primary outcome measures will be compared between a treatment group of participants, who will receive ESP blocks and a control group who will receive a sham block. Our primary hypothesis is that ESP blocks significantly reduce postoperative pain and opiate requirements
