New developments in epidural anesthesia and analgesia

Several recent advances in epidural anesthesia and analgesia have been reviewed. Perhaps the most exciting area of anticipated future developments relates to the continued development of novel analgesic agents and new epidural delivery systems. There appears to be some movement toward an increased use of intrathecal or peripheral neural blockade techniques for some clinical situations where epidural anesthesia and analgesia have been previously used; however, the ability to provide anesthesia and analgesia to relatively large areas of the body with a single injection or continuous catheter technique without the associated risks of dural puncture and intrathecal catheter placement will continue to assure epidural anesthesia and analgesia techniques a prominent role in anesthesia and pain management.
