Epidural Pressures and Spread of Epidural Anesthesia

Abstract

  The author overviewed the reports that covered the relationship between epidural pressure and the spread of epidural anesthesia, and found no evidence that the patency of the intervertebral foraminae was directly related to the epidural pressure after epidural anesthetic injection. Epidural compliance and epidural resistance may have an important role in determining the epidural pressure after epidural anesthetic injection.
