The findings of her metaanalysis lend more weight to the notion that so-called mobile epidurals, which use low doses of analgesia to preserve motor function, reduce the odds of a woman requiring an instrumental delivery. Still, low-dose epidurals don't make much of a dent in cesarean section rates, Dr. Angle said in a poster presentation at the annual meeting of the Society for Obstetric Anesthesia and Perinatology.

All trials compared the modes of delivery from low- and high-dose epidural using bupivacaine only.
