Background: Systemic analgesics should be used carefully when treating patients following renal surgery since these patients often have compromised renal function. Therefore, in such individuals, the localized nerve block may be a useful choice. This study's objective was to assess the effectiveness of transmuscular and anterior subcostal QLBs as a secure substitute for thoracic paravertebral blocks guided by ultrasonography for treating immediate postoperative pain in patients having open kidney operations. Methods: This prospective randomized double blinded study was carried out on 54 adult patients who underwent elective open renal surgeries. Patients were randomly classified into three equal groups, all were guided by ultrasonography: Group I: Transmuscular QLB, group II: Anterior Subcostal Quadratus Lumborum (ASQL) Block, and group III: Thoracic Paravertebral (TPV) Block. Results: Regarding the beginning of sensory block, overall intraoperative fentanyl usage, period to first rescue analgesic demand, and overall morphine consumption, there was a substantially significant difference between the three groups (P-value |
