Ultrasound-guided trans-incisional quadratus lumborum block versus ultrasound-guided caudal analgesia in pediatric open renal surgery: a randomized trial.


The caudal route is a common approach to providing postoperative analgesia. However, it may have some adverse effects and a limited duration of action. Quadratus lumborum block (QLB) may produce considerable, prolonged postoperative analgesia. Therefore, this study aimed to assess the postoperative analgesic effectiveness of ultrasound-guided caudal block to ultrasound-guided trans-incisional QLB (TiQLB) in pediatric patients undergoing open renal surgery.
