Overview
This prospective, randomized, assessor-blinded study is designed to evaluate the postoperative analgesic efficacy of the ultrasound-guided continuous erector spinae plane (ESP) block in patients undergoing thoracotomy. We hypothesize that US-guided ESP block is not inferior to thoracic epidural analgesia in terms of postoperative pain control in these patients.
Description
Adult patients undergoing elective unilateral thoracotomy for lung cancer resection are randomly allocated to receive US-guided ESP block (n=31) or thoracic epidural analgesia (n=31). Both procedures are performed prior to surgery. Each patient was assessed by a blinded investigator on postoperative day (POD) 1,2 and 3. The primary outcome is pain severity evaluated by a numeric rating scale (NRS) at POD1.
