Can a smarter epidural pump reduce leg weakness during labor?

This trial tests a new epidural pump method for women in labor. The method, called variable volume automated mandatory boluses, delivers pain medication in a way that may spread the drug more evenly, potentially reducing leg weakness while still controlling pain. The study includes healthy first-time mothers at term with a single baby, who request an epidural. Researchers will compare this new method to standard care, looking at how often motor block occurs and whether it affects the need for assisted delivery.
