Postoperative Analgesia in Patients Undergoing Percutaneous Nephrolithotomy

Intravenous Lidocaine Infusion Versus Ultrasound Guided Erector Spinae Plane Block for Postoperative Analgesia in Patients Undergoing Percutaneous Nephrolithotomy

Percutaneous nephrolithotomy (PCNL) is a minimally invasive procedure to remove stones from the kidney by a small puncture wound through the skin. Patients receiving lidocaine infusion had lower pain scores, reduced postoperative analgesic requirements and decreased intraoperative anesthetic requirements. Erector spinae plane block (ESPB) seems to be effective when compared with no block or a placebo block.
