Summary

Effective control of postoperative pain following pediatric lower urogenital surgery is important for enhancing recovery and reducing opioid requirements. Anterior quadratus lumborum block and retrolaminar block are two ultrasound-guided truncal block techniques used for perioperative analgesia in lower abdominal surgery. However, direct comparisons of their analgesic efficacy in pediatric lower urogenital procedures remain limited.

This prospective, randomized, controlled trial will enroll 76 pediatric patients aged 6 months to 12 years with American Society of Anesthesiologists physical status I-III who are scheduled for elective lower urogenital surgery. Participants will be randomly assigned in a 1:1 ratio to receive either an anterior quadratus lumborum block or a retrolaminar block. Both techniques will be performed under ultrasound guidance in addition to standardized general anesthesia.

The primary outcome will be rescue analgesic requirement during the first 24 postoperative hours. Secondary outcomes will include postoperative pain scores, time to first rescue analgesic administration, intraoperative remifentanil consumption, adverse effects such as nausea and vomiting, and caregiver satisfaction. The study aims to compare the postoperative analgesic efficacy and safety of anterior quadratus lumborum block and retrolaminar block in pediatric patients undergoing lower urogenital surgery.

Conditions

  • Pediatric Regional Anesthesia
  • Retrolaminar Block
  • Pediatric Postoperative Pain

Interventions

PROCEDURE

Anterior Quadratus Lumborum Block

An ultrasound-guided anterior quadratus lumborum block will be performed after induction of general anesthesia. Following identification of the quadratus lumborum and psoas major muscles, 0.25 percent bupivacaine will be injected into the fascial plane between these muscles at a volume of 0.4 milliliters per kilogram.

PROCEDURE

Retrolaminar Block

An ultrasound-guided retrolaminar block will be performed after induction of general anesthesia. After identification of the target vertebral lamina, 0.25 percent bupivacaine will be administered into the retrolaminar plane at a volume of 0.4 milliliters per kilogram.
