Trial Outcomes & Findings for Loss of Resistance, w/wo Stimulation, For Epidural Placement (NCT NCT03087604)

NCT ID: NCT03087604

Last Updated: 2020-06-17

Results Overview

will be determined by the detection of a loss of sensation to cold (ice) in at least two contiguous dermatomal levels, 15 minutes after administration of a test dose of lidocaine through the epidural catheter. If a loss of cold sensation is found, then the epidural placement will be classified as successful. If no loss of cold sensation is found, then the epidural placement will be classified as unsuccessful.

Measure
Traditional Technique Group
In the traditional loss of resistance technique group, the epidural catheter will be placed after achieving loss of resistance to air. After placement of the catheter a standard test dose of 3+2 ml of 1.5% lidocaine with 1:200,000 epinephrine will be administered.Solution for Thoracic epidural block. Thoracic epidural block: Thoracic epidural block with epidural placed with a loss of resistance technique alone. Solution For Thoracic epidural block: Dose of 3+2 ml of 1.5% lidocaine with 1:200,000 epinephrine
Electric Stimulation Group
In the electrical stimulation group, following the location of the epidural space with a loss of resistance technique (using air), nerve stimulation will be utilized to elicit a myotomal contraction of the abdominal or thoracic wall. After placement of the catheter a standard test dose of 3+2 ml of 1.5% lidocaine with 1:200,000 epinephrine will be administered.Solution for Thoracic epidural block.Thoracic epidural block with Electrical Nerve stimulation Thoracic epidural block: Thoracic epidural block with epidural placed with a loss of resistance technique alone.
