Programmed intermittent boluses vs continuous epidural infusion in labor using an adrenaline containing solution: A randomized trial.

For labor epidural analgesia infusions, to optimize the analgesic effect, additional programmed intermittent boluses can be used as an alternative to patient-controlled boluses only. In this clinical trial, no differences in drug consumption or analgesic effect was observed when comparing these two different epidural bolus controls programs.
