Abstract

Etidocaine, 250 mg, intended for the epidural space was accidentally injected intrathecally. The CSF and blood levels of etidocaine are correlated with levels of sensory and motor anesthesia. The effectiveness of removing CSF and replacement with 20 mg aliquots of saline was assessed. Calculation of the volume of distribution is presented. The advisability of a 4 to 6 minute evaluation period after injection of a test dose is discussed. The patient had complete recovery of sensory and motor function.
