Summary

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.

Conditions

  • Postoperative Pain
  • Cryptorchidism

Interventions

PROCEDURE

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.

PROCEDURE

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
