Influence of Painless Delivery on the Maternal and Neonatal Outcomes Under the Guidance of New Concept of Labor

Objective: To explore the possible influence of painless delivery on the maternal and neonatal outcomes under the guidance of new concept of labor.

Methods: Primiparas who received painless delivery in our hospital were selected for this retrospective clinical study. They were divided into two groups, the experimental group and the control group. The experimental group received painless delivery with the application of new labor management, while the control group received painless delivery with the application of routine labor management. The maternal and neonatal outcomes (postpartum hemorrhage, postpartum urinary retention, fetal distress and neonatal asphyxia), the duration of first and second stages of labor, the total duration of labor, medical intervention during first stage of labor such as artificial rupture of membranes or the use of oxytocin, visual analog scale (VAS) scores upon complete cervical dilation, delivery method and maternal satisfaction rate were compared between the two groups.

Results: Among the 208 primiparas, 112 cases were enrolled in the control group and 96 cases in the experimental group. There were no significant differences in the incidences of postpartum hemorrhage, postpartum urinary retention, fetal distress and neonatal asphyxia between the two groups (all P>0.05). The duration of first and second stages of labor and the total duration of labor in the control group were shorter than those in the experimental group (all P<0.001). The rates of artificial rupture of membranes and intravenous use of oxytocin in the control group were higher than those in the experimental group (both P<0.05). The VAS scores upon complete cervical dilation in the control group were significantly higher than those in the experimental group (P<0.05). The vaginal delivery and maternal satisfaction rates were significantly lower in the control group than in the experimental group (both P<0.05).

Conclusion: Painless delivery under the guidance of new concept of labor has no significant influence on the maternal and neonatal outcomes. Instead, it can prolong the labor process, provide more delivery time for pregnant women, reduce the intervention measures during delivery, decrease the delivery pain and finally increase the natural delivery rate and their satisfaction with delivery, which is worth wide promotion in clinical practice.
