Effects of different timing selections of labor analgesia for primiparae on parturition and neonates

Abstract

Objective: To explore the effects of labor analgesia for primiparae with different stages of cervical dilation on parturition and neonates. Materials and methods: In the past three years, 530 cases of primiparae who had delivered in the Second People's Hospital of Hefei and were eligible for a vaginal trial of parturition were enrolled as the research subjects. Of these, 360 puerperae had labor analgesia, and the remaining 170 were taken as the control group. Those given labor analgesia were divided into three groups based on the different stages of cervical dilation at that time. There were 160 cases in Group I (cervical dilation 0.05). In the three groups with labor analgesia, the usage rate of oxytocin was higher than in the control group, and the differences were statistically significant (P 0.05). The differences in the neonatal Apgar score were not statistically significant among the four groups (P > 0.05). Conclusion: Labor analgesia might prolong the stages of labor but does not affect the neonatal outcomes. It would be optimal to conduct labor analgesia when cervical dilation reaches 3–4 cm.
