Safer epidural and spinal connectors

Inadvertent cross-connection of epidural local anaesthetic delivery systems with intravenous lines can cause significant morbidity and even death. Inadvertent intrathecal injection of toxic intravenous drugs has already led to many deaths. If epidural and spinal systems had the standard Luer lock connection reversed the problem would be prevented. The practical implications of this idea are explored. Patient safety would be enhanced if this system were adopted.
