Comparing erector spinae plane block with serratus anterior plane block for minimally invasive thoracic surgery: a randomised clinical trial.

Background: Minimally invasive thoracic surgery causes significant postoperative pain. Erector spinae plane (ESP) block and serratus anterior plane (SAP) block promise effective thoracic analgesia compared with systemically administered opioids, but have never been compared in terms of terms of quality of recovery and overall morbidity after minimally invasive thoracic surgery.

Methods: Sixty adult patients undergoing minimally invasive thoracic surgery were randomly assigned to receive either single-shot ESP or SAP block before surgery using levobupivacaine 0.
