The vertical obturator nerve block: A randomised controlled double-blind pilot trial.

Although epidural hypertonic saline has been used to treat chronic pain from epidural adhesions, few reports describe its use for acute postoperative pain (supplemental digital content, http://links.lww.com/EJA/A90). The safety of epidural hypertonic saline injections primarily stems from epidural lysis of adhesions, in which a solution containing hypertonic saline is injected to mechanically disrupt epidural scar tissue, and which is considered a well tolerated chronic pain procedure. Nerve irritation is not un-common following these injections, but typically resolves after several minutes to hours. Two non-lysis of adhesions hypertonic saline studies note few other complications.
