title: Effect of epidural analgesia on labor and delivery: a retrospective study.
abstract: Two groups of women have been retrospectively compared: 155 women who received analgesia and 1355 women who delivered without analgesia. The duration of the first stage, second stage, and total duration of labor was longer in epidural group, however epidural analgesia was not demonstrated as an independent risk factor for a prolonged labor. The variable most influencing the total duration of labor and the duration of the first stage was nulliparity; the variables most influencing the duration of the second stage were the older age, a reduced body mass index, a high newborn weight and nulliparity.
