Comparison between Ultrasound Guided Erector Spinae Plane Block and Quadratus Lumborum Block for Postoperative Pain Management in Patient Undergoing Open Nephrectomy

Abstract

Background: Nephrectomy is conducted to manage renal malignancies and for purpose of living donor kidney transplantation. This study aims to compare analgesic effectiveness of ESPB versus QLB type III in open nephrectomy surgeries. Methods: This randomized, double-blind trial was carried out on a cohort of 75 cases underwent open nephrectomy surgeries. patients were distributed into three evenly matched groups: Group I: received only general anesthesia (GA), group II: received ESPB and group III: received QLB type III. Results: Time of first rescue analgesia and recovery time were notably delayed in ESPB group and QLB group than controls (P
