Abstract

Objective. To evaluate the effect of epidural analgesia (EA) on the duration of labor, the incidence of uterine inertia (UI), the frequency of oxytocin use, and the rate of cesarean section with regard to parity. Subject and methods. One hundred and eighty labors with good maternal and perinatal outcomes in 2012 to 2013 were prospectively analyzed. The investigation enrolled parturients without severe somatic and obstetric/gynecologic diseases, with a full-term singleton pregnancy, cephalic presentation, and spontaneous delivery. Results. In parturients with and without EA, the duration of the first and second stages of labor averaged 524.41±165.26 and 86.84±50.54 minutes and 406.81±167.06 and 59.81±59.31 minutes, respectively (р<0.0001). In primiparas with EA, the duration of the second stage of labor and the frequency of oxytocin use were significantly higher. In secundiparas, the longer average duration of the first and second stages of labor was due to the higher incidence of UI. Conclusion. EA increases the average duration of two stages of labor in the primiparas and the incidence of UI in the secundiparas, which determines the higher frequency of oxytocin use. EA has no effect on the rate of cesarean section and perinatal outcomes in the examined low-risk groups.
