Thoracic epidural and paravertebral blocks are gold standard analgesic techniques but they are associated with complications. Erector spinae plane (ESP) block is safer with comparable pain relief. ESP block is an established technique for postoperative pain relief. Its intraoperative use as an adjuvant to general anaesthesia (GA) is not yet known. The aim of this study was to assess the efficacy of ESP as an adjuvant to GA during laparoscopic surgery.
