Comparison of Posterior QLB and QIPB in Pediatric Undescended Testis Surgery.

Официальное название

Comparison of the Effects of Posterior Quadratus Lumborum Block and Quadroiliac Plane Block on Analgesic Consumption in Postoperative Pain Management in Pediatric Patients Undergoing Undescended Testis Surgery

Обзор

This randomized, double-blind study compares the postoperative analgesic efficacy of ultrasound-guided Posterior Quadratus Lumborum Block (QLB) versus Quadroiliac Plane Block (QIPB) in pediatric patients aged 1-7 years undergoing unilateral undescended testis surgery.

Подробное описание

Lower abdominal surgeries, such as undescended testis repair (orchiopexy), are common in pediatric patients and can cause significant postoperative pain. While Posterior Quadratus Lumborum Block (QLB) is a known technique for somatic and visceral analgesia, the Quadroiliac Plane Block (QIPB) is a newer approach targeting the fascial plane posterior to the iliac bone.

In this prospective, randomized, controlled trial, 70 pediatric patients (ASA I-II, aged 1-7 years) will be randomly assigned to receive either a Posterior QLB or a QIPB under general anesthesia. Both blocks will be performed using ultrasound guidance with 0.5 mL/kg of 0.25% bupivacaine.

The study aims to evaluate and compare the analgesic efficacy of these two techniques. Postoperative pain will be assessed using the FLACC scale. Secondary objectives include comparing the time to first rescue analgesic, total analgesic consumption, and incidence of complications.

Вмешательства

• Процедура Ultrasound-guided Posterior Quadratus Lumborum Block.
  Patients will be placed in the lateral decubitus position. Under ultrasound guidance, the probe will be placed at the posterior axillary line. The needle will be advanced to the posterior fascial plane of the quadratus lumborum muscle. A total of 0.5 mL/kg of 0.25% Bupivacaine will be injected.
• Процедура Ultrasound-guided Quadroiliac Plane Block
  Patients will be placed in the lateral decubitus position. Under ultrasound guidance, the probe will be placed at the level of the iliac crest. The needle will be targeted to the plane where the quadratus lumborum muscle attaches to the iliac bone. A total of 0.5 mL/kg of 0.25% Bupivacaine will be injected
