Comparison of Standard Epidural and Dural Puncture Epidural Analgesia in Open Gynecological Surgery Techniques

"Using the 18G Tuohy needle in the sitting position, the epidural space will be determined from the L3-L4 or L4-L5 space using the loss-of-resistance method After Dural puncture will be performed using a 25G Whitacre needle from the Tuohy needle to patients in the DPE group and free CSF flow will be observed, but no medication will be applied to the subarachnoid space. Afterwards, epidural catheter will be placed and when the catheter is fixed, a test dose of 3 mL will be administered through the catheter to check for intravascular or subarachnoid catheter placement.~An epidural local anesthetic will be administered throughout the catheter for intraoperative analgesia at 0,1% (bupivacaine+fentanyl+ saline) concentration with the NoL monitor guidance."

"The neuraxial procedure will be performed in the sitting position using the 18G Tuohy needle, in the L3-L4 or L4-L5 range using the loss-of-resistance method.~The epidural catheter will be placed so that it remains 4 to 5 cm in the epidural space. After the catheter is fixed, a test dose of 3 mL will be administered through the catheter to check for intravascular or subarachnoid catheter placement.~An epidural local anesthetic will be administered throughout the catheter for intraoperative analgesia at 0,1% (bupivacaine+fentanyl+ saline) concentration with the NoL monitor guidance."
