No results posted yet for this study

Summary

The aim of this study is to compare the effectiveness of standard epidural and dural puncture epidural analgesia techniques used under NOL guidance.

The primary aim of this study was to evaluate the effect of NOL-guided antinociception on intraoperative total local anesthetic consumption during anesthesia.

The secondary aim is to compare onset time, analgesia duration time, hemodynamic parameters, time to first postoperative analgesic requirement, and postoperative side effects.

Conditions

  • Analgesia

Interventions

PROCEDURE

Dural Puncture Epidural (DPE)

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.

PROCEDURE

Standart Epidural

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.
