ABSTRACT
Most of the errors encountered during drug applications of anaesthesia may arise from the selection of the wrong syringe and ampule, confusion of epidural and intravenous line, or incorrect dose administration. In this case report, accidental application of reversal drugs via epidural catheter to a patient who was operated on for ureterovesical stenosis is presented. We aimed to indicate the drug errors in anaesthesia practices and discuss measures to be taken to prevent it.
