Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
To investigate the use of ultrasound and manometry to increase the success rate of thoracic epidural placement. The use of ultrasound for lumbar epidural catheter placement is well established and is thought to assist in identifying an optimal skin entry point, depth to lamina and ligamentum flavum, and needle trajectory. The use of sterile manometry tubing to demonstrate a falling and oscillating fluid column has been described as a confirmatory test in the placement of lumbar epidurals. This study will determine if the efficacy of thoracic epidural placement is improved if placement is performed with the use of either US, or manometry, or both techniques combined, compared with a standard landmark-based placement technique alone.
