Abstract

General anesthesia (GA) is the preferred anesthetic modality for open renal surgeries to ensure a patent airway while the patient is in the lateral decubitus position. However, these surgeries are usually accompanied by severe postoperative pain with increased requirements for multimodal pain management strategies. Regional blocks provide better postoperative pain control with less systemic opioid consumption. The aim of this study was to describe the ultrasound (US)-guided transincisional quadratus lumborum block (TiQLB) as a new approach, and to compare the addition of dexmedetomidine to bupivacaine versus bupivacaine alone for TiQLB in combination with GA regarding postoperative analgesia and adverse effects in open renal surgery. A prospective, randomized, double-blind, controlled trial. Ain Shams University Hospitals. Eighty patients who were scheduled for an elective open renal surgery, aged 20 to 65 years, of either gender, and American Society of Anesthesiologists physical status I to II were enrolled in the study. They were randomly allocated into 2 equal groups: group dexmedetomidine-bupivacaine (DB) (n = 40) in which patients received combined GA plus TiQLB with 30 mL bupivacaine 0.25% plus 1 mu g/kg dexmedetomidine,...Continue Reading
