Key result
Epidural anesthesia is linked to a ~54% shorter first stage of labor in primiparous women.
Why the study?
Does epidural anesthesia reduce the duration of labor in parturients having spontaneous singleton vaginal delivery?
Observational (n=1,206)
Does epidural anesthesia reduce the duration of labor in parturients having spontaneous singleton vaginal delivery?
Epidural anesthesia significantly shortens the duration of both the first and second stages of labor in singleton vaginal deliveries.

Epidural use was associated with shorter labor stages; hypothesis-generating and should not change practice without RCTs.
Influence of epidural anesthesia on the duration of labor was studied in 1,206 parturients having spontaneous singleton vaginal delivery. In primiparous women, the mean first stage was 3.52 hr in the epidural group, and 7.68 hr in the control group (p less than 0.001), the mean second stage was 25.78 min in the epidural group, and 43.58 min in the control group (p less than 0.001). In the multiparous women, the mean first stage was 2.06 hr in the epidural group, and 3.85 hr in the control group (p less than 0.001), the mean second stage was 17.06 min in the epidural group, and 25.42 min in the control group (p less than 0.0001). The conclusion is that epidural anesthesia shortens the duration of first and second stages of labor in singleton vaginal delivery.

Lurie et al. (1991) conducted an observational in Labor (n=1,206). Epidural anesthesia vs. Control group was evaluated on Duration of first stage of labor in primiparous women (hours) (p=<0.001). Epidural anesthesia significantly shortened the mean first stage of labor in primiparous women (3.52 vs 7.68 hours, p<0.001) and multiparous women (2.06 vs 3.85 hours, p<0.001).
