Abstract
The dural puncture epidural technique is a modification of the combined spinal
epidural technique, where a dural perforation is created from a spinal needle but
intrathecal medication administration is withheld, followed by placement of a
catheter into the epidural space. (3)
The dural puncture creates a conduit for translocation of medications from the
epidural to subarachnoid spaces, a process that is believed to be responsible for the
unique characteristics that are observed with the DPE technique. DPE has been
shown to improve sacral block onset and spread of anesthesia, allows verification
of epidural space proximity, improved hemodynamic stability, assessment of
epidural catheter function, and reduced unblocked segments compared with
epidural
