Bilateral RSB vs TEA Epidural Analgesia for Postoperative Pain Control After Open Gastrectomy: A Randomized Controlled Trial

Patients indicated for elective open gastrectomy were screened, enrolled, and randomised between October 2021 and September 2023. The patients were randomised to either Group A (intervention-continuous bupivacaine) or Group B (control-NaCl saline). The primary outcome measures were the quantity of an opioid analgesic administered during the initial 72 h post-surgery and the level of postoperative pain as indicated by the visual analogue scale (VAS
