Background: During the last decades, the age of pregnant women significantly increased. The incidence of maternal and labor complications is higher among older women, but conclusive data have not been delivered whether labor epidural analgesia (EA) may affect the duration of labor and delivery outcomes in this population of patients. The aim of this study is to evaluate the effect of EA among women aged over 35 years.
Methods: We retrospectively reviewed medical records of all, singleton, at term deliveries, laboring with EA, between December 2011 and October 2017. Women aged ≥35 years (study group) were compared with women aged <35 years (control group) to evaluate EA effects on the duration of labor and neonatal outcome.
Results: The study enrolled 459 women with EA: 122 women were included in the study group and 337 in the control group. The multiple regression analysis showed that parity was an independent variable for a shorter dilation period (p = .002), second stage length (p = .0001) and for the total labor duration (p = .0001); neonatal weight was significant for a shorter dilation period (p = .005) and for the total labor duration (p = .002); maternal age and cervical dilatation at the beginning of EA did not influence neither the period of the labor stages nor the total labor duration (p > .05).
Conclusions: Results of this study indicate that women aged ≥35 with EA may have labor duration and neonatal short-term outcomes similar to younger women with EA.
