Reversal of prilocaine epidural anesthesia using epidural saline or ringer's lactate washout.

Background And Objectives: Several investigators have described the phenomena of epidural saline washout using bolus injections. This study was designed to determine whether epidural block could be reversed more effectively by infusion of crystalloid solutions via the epidural catheter.

Methods: One hundred male patients scheduled for outpatient surgery were enrolled in this study.
