Does Ultrasound Scanning of the Lumbar Spine Improve Patient Satisfaction and the Ease of Insertion Epidurals?

Ultrasound scanning of the back has been shown to increase success when used to guide epidural catheter insertion. However, this technique is not applied widely in clinical practice. Stronger evidence is required to prove that it will improve the clinical experience of labour epidurals. The study hypothesis is that anesthesiologists (both residents and fellows), will have an increased rate of success and ease of insertion of labour epidural catheters, and that there will be increased patient satisfaction, if ultrasound scanning of the lumbar spine is done prior to the procedure.
