Anatomical Measurements of Pudendal Nerve Block in Children

Condition(s) studied

Investigational drug(s) / intervention(s)

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.

Study 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.

Eligibility

Primary outcome measure(s)

• Horizontal distance from anus to needle insertion point and Depth from skin surface to pudendal nerve — During pudendal nerve block procedure
  The horizontal distance from the anus to the needle insertion point is measured in centimeters for each patient using neurostimulation-guided pudendal nerve block. Measurements are recorded separately for the right and left sides.The depth from the skin surface to the pudendal nerve is measured in centimeters using neurostimulation guidance. Measurements are recorded separately for the right and left sides. The relationship of this distance and the association of nerve depth with patient age, height, and weight will be analyzed.
