Regional anesthesia and pain medicine
-
In thoracic epidural anesthesia, the "loss of resistance" technique is the standard technique for the identification of the epidural space (EDS), the feedback to the operator is often solely tactile. Our aim was to establish ultrasonography for the prepuncture demonstration of the anatomic structures surrounding the thoracic EDS and to evaluate its precision and imaging quality. ⋯ US showed good correlation with MRI, which is a standard imaging technique for the depiction of the spine. We anticipate that prepuncture ultrasonography may facilitate thoracic epidural anesthesia by needle placement.

Case ReportsForaminal injection of a painful sacral nerve root using an epidural catheter: case report.
Nerve root pain has been treated with steroid injections since the 1970s. We will describe a novel method for nerve root injection using a directed epidural catheter. ⋯ This is a novel approach to treatment of painful nerve roots with a catheter.
