Anatomical Measurements of Pudendal Nerve Block in Children
Sponsor: Istanbul University - Cerrahpasa
Summary
This prospective observational study aims to investigate the relationship between anatomical parameters-specifically the distance from the anus to the needle insertion point and the depth required to reach the pudendal nerve-during neurostimulation-guided pudendal nerve block and patients' age, height, and weight in children undergoing penile surgery.
Official title: Investigation of the Distance of the Needle Entry Point From the Anus and the Depth to Reach the Pudendal Nerve in Pudendal Nerve Block Application in Children

Interventions
Neurostimulation-Guided Pudendal Nerve Block
Bilateral pudendal nerve block is performed under general anesthesia with neurostimulation guidance. Anatomical measurements, including distance from anus to needle insertion point and nerve depth, are recorded for each patient. Bupivacaine 0.25% is used at 0.25 ml/kg per side, with a maximum total dose of 2 mg/kg.
