Epidural pressure changes following caudal blockade: a prospective, observational study.

Purpose Recent case reports raise the question as to whether anesthetic agents injected into the epidural space could lead to a ‘compartment syndrome’ and neurovascular sequelae. Single-shot caudal epidural anesthesia has been established as a safe technique, but changes in pressure in the caudal epidural space have not been described. Our aim was to study pressure changes to provide preliminary information for future studies design.
