Abstract

Objectives: To compare the effects of ultrasound guided erector spine plane block (ESPB) with serratus anterior plane block (SAPB) for thoracotomy under general anesthesia. Background: Patients undergoing thoracotomy often experience severe postoperative pain. Inadequate control of this pain increases the risk of postoperative complications and may develop into chronic pain. There is no golden standard for the management of postoperative pain following thoracotomy. Interfascial nerve blocks are proposed as simple and effective techniques. Methods: Thirty adult patients, ASA I-II, 18-60 years old, scheduled for thoracotomy, between April 2021 and June 2022. Patients were randomized into two groups 1:1 ratio (15 patients each). Group A received US guided ESPB and group B received US guided SAPB. In both blocks, the injectate was 20ml bupivacaine 0.25%. Both blocks were performed as a single injection after induction of general anesthesia. Results: The ESPB group showed a significant lower VAS score than SAPB group till 8 hours postoperatively (P
