Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
In this study the patients will receive an epidural catheter in the same way as standard of care. The catheter will be inserted to 20cm and then electrically stimulated to document where it is placed by looking at the muscles effected. The catheter is then pulled back in 5cm increments and stimulated until the standard distance is achieved. For example, if loss of resistance happened at 5cm, the catheter would be inserted to 20cm, stimulated, pulled back to 15cm and stimulated, and finally to 10cm and stimulated.
Electrical stimulation of epidural catheters for confirmation of placement is a published and accepted technique. In this study, the investigators will perform electrical stimulation at incremental points during catheter pull back with documentation of where stimulation was seen.
