Objective: To describe and compare the obstetric and perinatal outcomes in patients with or without obstetric analgesia during labor, and to determine whether such analgesia is associated with adverse maternal or perinatal outcomes.
Methodology: Comparative, retrospective, descriptive study, between January and November 2014, that included 502 healthy patients with normal pregnancies, out of which 250 received obstetric analgesia. The groups were compared as to maternal and perinatal outcomes.
Results: Young, single and nulliparous mothers predominated; delivery was vaginal in 86 % of the cases, and by caesarean section in 14 %. Obstetric analgesia was associated with longer duration of the second stage of labor, instrumental delivery and cesarean section due to arrest of dilatation or fetal bradycardia; however, it was not related with higher incidence of postpartum hemorrhage or adverse perinatal outcomes such as meconium-stained amniotic fluid, Apgar under 5 at one minute or under 7 at 5 minutes, the need for neonatal resuscitation or for admission to NICU.
Conclusion: Obstetric analgesia increases the duration of the second stage of labor and can increase the rate of caesarean sections and instrumental delivery, but it is not associated with adverse maternal or perinatal outcomes. Therefore, its use in labor is justified.
