Erector Spinae Plane Block v.s Patient Controlled Analgesia in Correction Surgery for Idiopathic Scoliosis

Scoliosis correction surgery involves extensive surgical wounds, intense intraoperative stimulation, and severe postoperative pain, often necessitating the use of potent opioids. However, there is a critical clinical need for effective pain management strategies that both ensure sufficient analgesia and minimize opioid-related adverse effects. The Erector Spinae Plane Block (ESPB) has shown promise as an effective analgesic technique, but its application in scoliosis correction surgery has not been reported.We hypothesize that ESPB provides superior postoperative analgesia compared to patient-controlled intravenous analgesia (PCA) pumps. Specifically, ESPB is expected to significantly reduce postoperative pain scores, decrease perioperative opioid consumption, and mitigate opioid-related side effects.

This study is a randomized controlled trial involving 40 participants undergoing scoliosis correction surgery, randomized into two groups: the ESPB group and the PCA group. The primary outcome measure is the resting pain score at 2 hours postoperatively, which will be used to evaluate the efficacy of ESPB. Secondary outcomes include perioperative opioid consumption and the incidence of opioid-related adverse effects. The study aims to provide evidence for ESPB as an innovative and effective method for postoperative analgesia in scoliosis correction surgery.
