\- DPE technique was performed in the sitting position at the L3/4 or L4/5 interspace via the midline approach using a 17-gauge Touhy needle and a loss of resistance to saline technique, then the dura was punctured with a 25-gauge pencil point Whitacre spinal needles using a needle-through-needle technique, and spontaneous flow of cerebrospinal fluid was confirmed, then the spinal needle was removed and a flexible 19-gauge, spring closed-tip catheter was inserted 5 cm into the epidural space toward the cranial side.
