ABSTRACT

Objective To evaluate the effect of labor analgesia on maternal and neonatal outcomes. Methods The medical records of mature puerperas with singleton pregnancy from October 2018 to April 2019 at the General Hospital of Ningxia Medical University were retrospectively reviewed. Puerperas were divided into non-labor analgesia group ( NLA) and labor analgesia group ( LA) according to whether or not puerperas received labor analgesia. Maternal and neonatal outcomes were analyzed. Maternal outcomes in-cluded delivery mode, complications, intrapartum hemorrhage and blood loss at 24 h after birth, duration of the second stage of labor and prolongation, episiotomy and length of hospital stay after birth. Neonatal outcomes included Apgar score at 1, 5 and 10 min after birth, cases of Apgar score＜7 at 5 min after birth, and the proportion and reason of transfer to pediatrics unit. Results A total of 839 puerperas were includ-ed, with 551 cases in NLA group and 288 cases in LA group. Compared with NLA group, the second stage of labor was significantly prolonged ( P＜0. 01) , and no significant change was found in the other maternal or neonatal outcomes in LA group ( P＞0. 05) . Conclusion Labor analgesia can prolong the second stage of labor and exerts no effect on the neonatal outcomes.
