Brief summary

Caudal epidural block has been a widely used regional anesthesia method, especially in pediatric surgery, to provide intraoperative and postoperative analgesia. Studies on non-invasive methods used for intracranial pressure measurement have shown that optic nerve sheath diameter is related to intracranial pressure. Optic nerve sheath diameter measurement has high diagnostic accuracy for detecting increased intracranial pressure in children. The aim of the study is to investigate the effect of the caudal block on optic nerve sheath diameter in pediatric patients.
