Erector spinae plane block (ESPB) is a novel technique that provides postoperative analgesia and reduces opioid consumption. Our aim is to explore whether ESPB produces analgesia similar to thoracic epidural anaesthesia (TEA) in paediatric patients undergoing Nuss procedure.Study Design and Methods: This randomized, controlled, non-inferiority trial will enrol 300 paediatric patients undergoing Nuss surgery. Participants will be randomly assigned 1:1 to receive ESPB or TEA preoperatively. The primary, joint endpoint is the average numeric rating scale (NRS) score and cumulative sufentanil consumption. The secondary endpoints are pain scores and sufentanil consumption at different time points after surgery, analgesia-related side effects, and other postoperative complications. Data will be analysed by the intention-to-treat principle.Discussion: This study investigates the effect of ESPB on postoperative opioid consumption and pain scores and intend to provide a new strategy of analgesia management for Nuss procedure in paediatric patients.Keywords: postoperative pain, erector spinae plane block, pectus excavatum, Nuss procedure, opiates
