Is tissue coring to the epidural space during caudal blockade possible in children?

Abstract

Caudal blockade is performed easily by penetrating sacrococcygeal membrane which covers sacral hiatus. Caudal blockade in children is simple and reliable technique for a wide ranger of surgical operations. It is the most frequent regional anesthetic technique used in children, accounting for almost 50% of all regional techniques. Although the long-term consequences of caudal injection are unknown, some authors suggested that epidermoid tumors might develop by coring the epithelial tissue after subarachnoid or epidural injection. The presence of the mytotic activity of the coring tissues during caudal blockade is another important point.
