Abnormal motor blockade after epidural analgesia caused by pneumorrhachis and the role of hyperbaric oxygen treatment: a case report.

Previous reports have associated such events with epidural insertion using a loss of resistance (LOR) to air technique. This report describes a case of symptomatic epidural pneumorrhachis following epidural anaesthesia using LOR to saline.
