Comparison of the Analgesic Efficacy of Transversalis Fascia Plane Block and Posterior Quadratus Lumborum Block in Pediatric Patient Undergoing Orchiopexy: A Prospective Observational Study

It was planned to compare the analgesic efficacy of the transversalis fascia plane block and the posterior quadratus lumborum block in children aged 1 to 7 years undergoing orchiopexy, by evaluating their FLACC scores and the time to first postoperative analgesic requirement.

Treatment and study plan

Primary outcomes

Time to First Analgesic Requirement After Surgery

Time frame: First 24 hours postoperatively

The time elapsed from the end of surgery to the administration of the first rescue analgesic.

Secondary outcomes

FLACC Pain Scores at Specified Time Intervals

Time frame: First 24 hours postoperatively

Pain assessment using the Face, Legs, Activity, Cry, Consolability (FLACC) scale (score range: 0-10; higher scores indicate worse pain) at 30 minutes, 1 hour, 2 hours, 4 hours, 6 hours, 12 hours, and 24 hours postoperatively.
