Evaluating ultrasound for locating epidural catheters in surgery
"Diagnostic Accuracy of Ultrasound Compared to Epidurography for Epidural Catheter Localization in Patients Undergoing Open Abdominal Surgery"
This study tests if using ultrasound to find epidural catheters is as reliable as the traditional method for patients having major abdominal surgeries.

What this trial studies
This clinical trial aims to assess the diagnostic accuracy of ultrasound in locating epidural catheters compared to the traditional method of epidurography. It focuses on patients undergoing major open abdominal surgeries, who typically experience significant postoperative pain. Participants will receive epidural analgesia and have their catheter placements verified using both ultrasound and epidurography. The study seeks to determine if ultrasound can serve as a reliable alternative to epidurography in surgical settings where the latter may not be feasible.
Who should consider this trial
Good fit: Ideal candidates for this study are adults aged 18 years or older scheduled for major open abdominal surgery requiring epidural analgesia.
Not a fit: Patients with contraindications to epidural analgesia or those with cognitive impairments that prevent them from completing necessary assessments may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could provide a more accessible and effective method for ensuring proper epidural catheter placement, leading to improved pain management for patients after surgery.
How similar studies have performed: While the use of ultrasound for catheter localization is gaining interest, this specific comparison with epidurography is relatively novel and has not been extensively tested in prior studies.
