Comparative StudyCatheter failure rates and time course with epidural versus combined spinal-epidural analgesia in labor.
The combined spinal-epidural technique for labor analgesia has several advantages over the traditional epidural technique, including faster onset, greater maternal satisfaction, and decreased need for physician boluses. Proponents of the epidural technique criticize the combined spinal-epidural technique, arguing that the epidural catheter remains untested and thus may not be reliable if needed for surgical intervention. We compared failure rates and time of failure between techniques in our tertiary-care academic practice. ⋯ We were able to demonstrate that catheters placed using a combined spinal-epidural technique were less likely to fail during labor and that the time to detection of a failed catheter was significantly longer in the combined spinal-epidural group. Our findings validate the combined spinal-epidural technique as reliable for labor analgesia and tend to refute the theory of the untested catheter.
