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

Comparison of the Analgesic Efficacy of Posterior Quadratus Lumborum Block and Transversalis Fascia Plane Block in Children Undergoing Orchiopexy

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.

Inclusion Criteria:

• Children aged 1 to 7 years with ASA physical status I-II undergoing unilateral orchiopexy surgery.

Exclusion Criteria:

• ASA physical status ≥ III
• History of prematurity (gestational age < 37 weeks) Known coagulation disorders or bleeding tendency
• Infection, inflammation, or skin lesion at the injection site
• Known neurological or neuromuscular diseases
• Presence of significant cardiac or pulmonary disease (e.g., congenital heart disease, active asthma)
• Hepatic or renal dysfunction
• Known allergy or hypersensitivity to local anesthetics (e.g., bupivacaine, lidocaine)
• Developmental delay or cognitive impairment that prevents accurate pain assessment
• Use of additional regional analgesia techniques (e.g., caudal block) during surgery
• Block failure or intraoperative complications requiring exclusion from protocol analysis
• Lack of parental consent for participation in the study
