Spinal analgesia during labor with low-dose bupivacaine, sufentanil, and epinephrine. A comparison with epidural analgesia.

Background And Objectives: The purpose of this investigation was to evaluate the effectiveness and side effects of combined spinal-epidural (CSE) injection of a bupiv-acaine-sufentanil-epinephrine mixture during labor as compared with epidural analgesia alone.
