Ultrasound-Guided Transmuscular Quadratus Lumborum Block Provides Effective Postoperative Analgesia for High Ligation of Spermatic Vein

Abstract

Postoperative pain management after varicocele surgery poses a challenge for pediatric patients. The quadratus lumborum block (QLB) is a novel regional analgesia technique that entails injecting a local anesthetic around the quadratus lumborum muscle using ultrasound guidance. In this study, we present the utilization of a single transmuscular QLB in two children as an effective postoperative analgesic method for laparoscopic extraperitoneal high ligation of the spermatic vein (LEHLSV).
