Opioid-sparing effect of modified intercostal nerve block during single-port thoracoscopic lobectomy: Retraction: A randomised controlled trial.

Background: Peripheral local anaesthetic blockade has an important role in multimodal postoperative analgesia after video-assisted thoracic surgery. Intercostal nerve block has an opioid-sparing effect after thoracoscopic surgery, but there is little information about an intra-operative opioid-sparing effect.

Objective: This prospective randomised trial was designed to evaluate the feasibility of a modified intercostal nerve block and its potential opioid-sparing effect during single-port thoracoscopic lobectomy.
